Description

  TECHNICAL FIELD The present invention relates to a wound-breaking prevention auxiliary tool for preventing wound-opening (further opening of a wound), and in particular, a treatment that can easily perform a treatment for excessive exudate, pus, necrotic tissue, and the like. The present invention relates to a treatment-compatible wound-opening prevention auxiliary tool including a corresponding excisable portion.

A wound created when a part of the body is scratched is called a wound. The wound is a wound when it is bruised with a blunt instrument, etc. It can be roughly divided into “scratches” that refer to closed flaws without cuts. Conventionally, for wounds that are open to the wound, if the wound floor is shallow, the wound is prevented from being opened and closed by means of closing and fixing the wound with adhesive bandages or bandages, etc. Has closed the wound by means of suturing with a suture or the like to prevent the wound from opening and closing.
Furthermore, as a means of suturing with sutures, etc., a thicker suture is selected from a plurality of sutures of appropriate thickness in order to prevent the wound from opening and closing due to the suture being cut by an external force or the like. The means used is universal.

However, the use of a thick suture is not preferable because the stitches of the suture are easily noticeable. In addition, the thicker the suture, the stronger the tissue surrounding the wound is pulled and the stronger the suture is, the worse the circulation of blood, etc. to the surrounding tissue of the sutured wound, and necrosis gradually occurs in the surrounding tissue of the sutured wound. Occurs.
Furthermore, suturing by open surgery or the like is performed by pulling the tissue around the wound. Therefore, the suture and the tissue surrounding the wound wound are attracted. If an external force is applied in this state, if the suture is thin, the suture is cut, and if the suture is thick, the tissue around the sutured wound is torn. That is, even if a suture having an appropriate thickness is selected and used, it is difficult to prevent the wound from opening and closing.

In some cases, a suturing device has been proposed to relieve pain of a patient by preventing the wound from opening at the time of suturing after incision surgery, and preventing compression, necrosis, etc. of the sutured skin by the suture thread. (For example, refer to Patent Document 1).
In Patent Document 1, in order to prevent stress from acting intensively on the affected tissue with a thin suture thread, an applicator having a large contact area to the affected area is prepared, and an elasticity imparting shape for applying tension to the thread is provided. In addition, a wound separation preventing applicator provided with a guide slit and a thread fixing slit for facilitating winding of a thread has been proposed.

As described above, in the conventional wound break-opening prevention tool including the above, it is indispensable to learn in advance a technique for mounting the wound separation-opening prevention tool during suturing such as incision surgery. In addition, when it becomes necessary to remove the brace during the follow-up of the affected area, treatment, disinfection of the brace, etc., it is necessary to acquire techniques corresponding to these in advance. Also, if the patch is removed, the function of preventing stress from acting intensively on the affected tissue that has been obtained by attaching the patch until now will be lost.
Furthermore, if the suture is cut or removed with the attachment and detachment of the brace, the force that has been prevented by the sutures that prevents the wound from opening and closing is lost. It can be easily predicted that separation will easily occur. For this reason, it is not easy to attach a patch to a wound other than a wound that does not require removal of the patch until the affected tissue is completely healed.

In addition, there are few books and papers that scientifically refer to the treatment of wound dissection, and not only cures but also prevention methods have not been established. In particular, for wound dehiscence caused by necrosis of the tissue surrounding the sutured wound due to poor circulation of blood, etc., the effect cannot be expected even if it is sutured again, and all of the suture thread is removed to remove the necrotic tissue. However, it may be necessary to switch to conservative treatment by covering with a wound dressing and expecting natural healing, and it is not uncommon for patients to be hospitalized or hospitalized for a long time.
In the case of re-treatment such as follow-up of the affected area, treatment and disinfection of the patch, and necrosis of the surrounding tissue of the sutured wound, it is necessary to remove and reattach the patch. The auxiliary tool for preventing wound separation is not easy to remove.

Incorporated as a function in the wound opening prevention tool, when the wound floor is shallow, the tissue surrounding the wound is loosened, lightly wrinkled, and the wound received by the wound surrounding tissue is released (hereinafter referred to as the wound). In the case where the wound floor is deep, loosen the tissue surrounding the sutured wound and lightly wrinkle it after suturing with a suture thread. , Continuously reduce the physiological tension in the wound opening / closing direction received by the tissue surrounding the sutured wound and the tension acting on the suture accompanying the physiological tension, and the wound separation and suture by cutting the suture after stitching Circulation of blood, etc. in tissues surrounding wounds sutured by It is possible to prevent SoHanareHiraki by necrosis or the like of sutured wounds surrounding tissues caused by.

  Further, it is possible to select and use a thinner suture from a plurality of sutures having appropriate thicknesses, thereby making the traces of stitches inconspicuous. Furthermore, depending on the state of the wound, it is possible to eliminate the need for suturing. In addition, it can be expected that wounds that are generally difficult to suture, such as heel wounds and bite wounds, can be prevented from opening and closing. Furthermore, regardless of whether the wound is sutured or not sutured, the wound and its surrounding tissue can be kept quiet, and natural healing can be accelerated.

  Furthermore, the wound separation / opening prevention part is provided with a part that can be arbitrarily resected for performing a treatment on the wound and its surrounding tissues (hereinafter referred to as a treatment-removable part), so that it can For wounds with good hygiene and early healing, it is easy to observe the wound and its surrounding tissues while wearing an auxiliary tool for preventing wound separation, resulting in excessive exudate and pus. If it is, the appropriate treatment or the like can be performed by appropriately excising the treatment-removable portion while maintaining the wound separation preventing function of the wound separation preventing assisting device.

  Furthermore, by providing a site (hereinafter referred to as “treatment opening”) that is open in accordance with an application such as treatment of the wound and its surrounding tissue in the treatment-removable portion provided in the wound separation prevention portion, For wounds with poor hygiene conditions such as bite wounds that are prone to infection and wounds that require multiple treatments, leave the wound and auxiliary tissue attached to the wound and surrounding tissues. Treatment with excessive exudate, pus, necrotic tissue, and the like can be performed while observing and maintaining the function of preventing dehiscence and opening of the auxiliary tool for preventing dehiscence and observing. In addition, the effect can be expected for an incision for insertion of a laparoscope or the like associated with intra-abdominal observation or surgery.

Furthermore, by providing a shrinkage prevention unit having a function of preserving a force (hereinafter referred to as a wound closing force) in a direction (hereinafter referred to as a wound closing direction) that opposes the wound opening and closing direction provided in the wound separation and prevention unit. Since the closing force can be maintained in a conserved state, the mounting becomes remarkably easy.
After the wound separation prevention part is closely attached to the wound and the surrounding tissue, and fixed and attached by the holding part, the wound closure force provided by the preserved wound separation prevention part is exhibited, and the wound separation prevention part is closed. It can be efficiently shrunk in the direction and function as an auxiliary tool for preventing wound separation.
It should be noted that the treatment-corresponding wound separation / opening prevention aid of the present invention can be used effectively regardless of whether the wound is in a sutured state or not.

It is a schematic plan view which shows the state at the time of mounting | wearing of the treatment corresponding type wound-opening prevention auxiliary tool shown in FIG. It is a schematic plan view which shows the shrinkage | contraction prevention part of the treatment corresponding type wound separation prevention auxiliary tool shown in FIG.

  The present inventor has found that in the process of earnest research, the cause of wound separation is closely related to the physical force accompanying the physiological action of the living body. For example, muscles are constantly subjected to physiological tensions due to the elasticity of the fascia, the underlying muscle fibers, and the skin, and the elasticity of the skin and the underlying muscle tissue. It is necessary to pull the muscles and skin to be sutured with sutures, the operator's fingers or instruments, etc. when sewing muscles and skin. This is because the muscles and skin that have been subjected to continuous physiological tension in the direction of wound separation and opening.

For this reason, in order to prevent the wound separation after the suture, it is important to continuously reduce the tissue tension around the suture wound and the physiological tension in the wound opening direction received by the suture thread. In addition, in order to accelerate the natural healing after suturing, it is necessary to keep the tissue surrounding the sutured wound at rest, but the tissue surrounding the sutured wound is continuously subjected to physiological tension in the direction of wound separation. It is difficult to keep rest.
However, the conventional assisting tool for preventing wound separation does not take into consideration the physiological tension in the wound opening direction received by the tissue around the wound wound and the suture thread.

  Here, toward the sutured wound, the tissue around the wound wound from the closing direction is loosened, lightly wrinkled, and the physiological tension in the wound opening direction received by the tissue surrounding the sutured wound and its physiological The continuous reduction of the tension acting on the suture due to the tension is an effective means for preventing the debridement by the suture cutting after the suture and the necrosis of the peripheral tissue of the wound sutured by the suture, etc. Become.

  Therefore, the present inventor has a wound separation prevention function having a function of continuously reducing the physiological tension in the wound opening / closing direction received by the tissue surrounding the sutured wound and the tension acting on the suture thread accompanying the physiological tension. In order to obtain an auxiliary device, select a material with elasticity that can be used for medical purposes, and then select a material with elasticity that surpasses physiological tension to construct an auxiliary device for preventing wound separation. did.

Therefore, by using materials with different contraction distances in each part of the auxiliary tool for preventing wound separation, the action caused by the difference in contraction distance in each part (when stretched with a constant force when wearing, the part with a long contraction distance is If you consider the friction between the material and the tissue around the wound, and the suture tissue around the wound, it will stretch further than the region with the shortest contraction distance (that is, the region with the longest contraction distance will shrink the most). A means for continuously reducing the physiological tension applied to the wound can be incorporated into the auxiliary device for preventing and separating the wound, and acts on the physiological tension in the direction of the wound and the suture along with the physiological tension. It was found that the tension can be continuously reduced and the wound separation can be prevented.
In the above, the contraction distance refers to a test piece cut out from a material used as a material for the auxiliary device for preventing wound separation, and a predetermined force is applied to measure the length of the stretch. It is the length obtained by subtracting the value of the contracted state as zero.

  Furthermore, by providing a treatment-compatible resectable portion in the wound-opening prevention portion that covers and installs the wound and its surrounding tissue, and a treatment-compatible resectable portion that includes a treatment opening portion, the wound-opening prevention auxiliary tool is not detached, It is possible to perform treatments on the wound and surrounding tissues while maintaining the wound separation prevention function of the auxiliary device for preventing wound separation, and consider the hygiene of the wound and the treatment on the wound that is supposed to be healed. In addition, the present inventors have obtained the knowledge that a treatment-corresponding wound-opening prevention assisting device that can select a wound-opening prevention assisting device suitable for a wound can be provided, and the present invention has been completed.

The treatment-corresponding wound-opening prevention assisting device of the present invention includes a wound-breaking prevention portion that has a wound-closing force that covers the wound and its surrounding tissue and contracts in the wound-closing direction, and the wound-breaking prevention portion is wound around the wound. And a holding part that is held in close contact with the tissue. It can be equipped with a function that is longer than the contraction distance in the direction of wound opening and tearing when attached, and the wound opening and closing part has the wound and opening prevention part in close contact with the wound and the surrounding tissue, and fixed and attached by the holding part. The basic principle is that the wound and the surrounding tissue are contracted in the closing direction by the closing force.
In addition, by providing the anti-shrinkage part in the wound separation prevention part, the wound closure force of the wound separation prevention part can be preserved, and the wound separation prevention part is brought into close contact with the wound and its surrounding tissues and fixed by the holding part. After the attachment, the wound-breaking force of the wound separation / prevention part which has been preserved can be exhibited, and the wound separation / breakage prevention part can be efficiently contracted in the wound-closing direction.

The contraction distance associated with wearing here refers to the stretched state caused by physiological movements of the body (changes in chest circumference and abdominal circumference due to breathing, etc.) that occur after wearing each part of the auxiliary device for preventing wound separation that can occur even at rest. It is the length obtained by subtracting the numerical value of the contracted state by making these loads zero.
In addition, the state in which the contraction distance in the direction of separation and opening accompanying the attachment of the wound separation prevention part is equal to or greater than the contraction distance in the direction of separation and opening of the holding part means that the contraction in the direction of separation and opening accompanying the attachment of the wound separation and prevention part The distance is a state that is at least equal to or longer than the contraction distance in the wound-opening direction accompanying the mounting of the holding part.

In addition, in order to enlarge the difference with the shrinkage distance accompanying mounting | wearing of a wound separation prevention part, it is desirable for a holding | maintenance part to be provided with a non-stretching function in a wound separation opening direction. However, the tissue around the sutured wound is loosened, lightly wrinkled, and the physiological tension in the direction of the wound opening and tear received by the tissue surrounding the sutured wound and the tension acting on the suture associated with the physiological tension are sustained. The holding portion may be provided with a function of expanding and contracting in the direction of opening and closing as long as it has a function of preventing the opening and closing of the wound.
In addition, as described above, the treatment-compatible wound-breaking-prevention assisting device of the present invention is mounted without detaching the wound-breaking-preventing assisting tool by providing the treatment-releasing resectable portion in the wound-breaking-preventing portion. As it is, treatment of the wound and surrounding tissues is possible.
In addition, you may provide the obstruction | occlusion part which has a function which obstruct | occludes the site | part which the treatment corresponding excisable part opened, or the treatment opening part, and this makes easy hygiene management, protection, etc. of a wound and its surrounding tissue.

In addition, the holding portions 2a to 2l may have any number or length of strings depending on the use, may have elasticity, may not be string-like, and use buttons, fasteners, or the like for holding. Alternatively, a medical pressure-sensitive adhesive may be applied to the surface that is in close contact with the skin. About connection part 3a, 3b, although the both ends of the wound-opening prevention part 1 were turned back and made it double, it is not necessary to provide a clear connection part. Moreover, although the connection parts 3a and 3b were made into the cylinder shape, the U-shaped metal material was inserted, and it was set as the structure provided with the shrinkage | contraction prevention part 4a, the shrinkage prevention part 4a has the closing force with which a wound separation prevention part is provided. As long as it has a function of preserving, there is no restriction on the material, shape, part, etc. according to the application.

Furthermore, in the above example, the shape of the treatment-removable portion 6 is rectangular, and a transparent vinyl sheet is used for the purpose of observation. However, the treatment-removable portion is preferably transparent, but depends on the shape, material, etc. It may be translucent or opaque as long as it has a function that makes it possible to treat the wound and surrounding tissue as needed without being limited, without removing the auxiliary tool for preventing wound separation and removal. In addition, a treatment opening may be provided in the lower layer of the treatment-removable portion, and further, the lower layer of the treatment-removable portion corresponds to a dressing material, excessive leachate, pus, etc. for preparing a wet environment in advance. A treatment material or the like may be provided.
In addition, a part or all of the wound separation prevention part and the holding part may have a multi-layer structure as necessary, and are not limited by the shape or material, but as a result, the direction of the wound separation accompanying the attachment of the wound separation prevention part It suffices to have a function in which the contraction distance is equal to or greater than the contraction distance in the direction of opening and closing associated with the mounting of the holding portion.
Furthermore, although the wound separation prevention part 1, holding | maintenance part 2a-2l, connection part 3a, 3b, and the treatment corresponding excisable part 6 were mutually sewn, you may use the manufacturing method without a seam or a seam in part or all.

  In addition to the above-mentioned materials, examples of the material that constitutes the treatment-compatible wound-opening prevention auxiliary tool of the present invention include chemical fibers such as nylon and natural fibers such as silk and hemp. What is provided with the softness | flexibility, heat retention, durability, etc. which were suitable for each of the prevention part 1, holding | maintenance part 2a-2l, connection part 3a, 3b, and the treatment corresponding excisable part 6 is preferable. These are examples and not limiting. Furthermore, depending on applications, materials such as plastic and metal may be used, and other new materials may be used as long as they are suitable for medical use.

  Further, the holding part has a function of holding the wound-breaking prevention part in close contact with the wound and its surrounding tissue, and the contraction distance in the wound-opening direction due to the wearing of the wound-breaking prevention part is the width of the wound-opening with the holding part. If it has the function which becomes more than the contraction distance of a direction, according to a use, the material, a shape, a part, etc. will not be restricted. For example, only the pressure-sensitive adhesive suitable for medical use may be used as a holding part and provided in a part or all of the lower layer of the wound separation prevention part. It is desirable to be equal to the contraction distance in the wound opening / closing direction accompanying the attachment of the separation preventing part, and depending on the shape of the wound opening / closing part or holding part, the contraction distance in the wound opening / closing direction accompanying the mounting of the holding part and the wound opening / closing preventing part There may be little difference with the contraction distance in the direction of wound opening and closing associated with the wearing of.

Furthermore, there is no need to make a clear distinction between the wound separation preventing portion 1 and the treatment-compatible resectable portion 6, and they may be made of the same material as long as both functions are provided. Moreover, when the material which reacts with humidity, a drug, or the component in air, etc. is used for the dehiscence prevention part 1, the shrinkage prevention part is a function which prevents these reactions. If the package or the like has a function of preventing these reactions, the package or the like is regarded as a shrinkage prevention unit.
When a shape memory alloy that responds to body temperature and exhibits the function of the wound separation prevention part 1 is used as the material of the wound separation prevention part 1, the shrinkage prevention part having a function of preserving the contraction of the wound separation prevention part is It can be considered that it is provided in the prevention part 1, and in such a case, it is not necessary to provide a clear shrinkage prevention part. As a result, it is not necessary to provide a clear shrinkage prevention part as long as it has a function of preserving the shrinkage of the wound separation prevention part even with other materials. Furthermore, a material such as a liquid or a gel that hardens after being attached to a part or all of the auxiliary device for preventing dehiscence may be used, and as a result, the function of each part of the auxiliary tool for preventing dehiscence according to the present invention is achieved. It only has to have.

  In the above, the example in which the auxiliary tool for preventing wound separation is mounted on the wound wound on the outer side of the forearm has been described, but the wound can be mounted regardless of whether the wound is in the sutured state or not. In addition, it can be attached to each part of the body regardless of the outer part of the forearm, and can have a shape suitable for each part. In the present invention, the close attachment to the tissue is not limited to the case where it is in direct contact with the tissue surface, and the function of the resectable portion corresponding to the treatment is secured without detaching the auxiliary tool for preventing wound separation. In such a state, the case where the wound is intimately contacted through a wound covering the wound and the surrounding tissue such as a dressing material or a treatment gauze for preparing a moist environment is also included. The same effect can be obtained even when a medical adhesive or stapler (stapler) is used without using a suture. It can be used regardless of whether the wound is sutured or not.

  The treatment-supporting wound-breaking prevention aid of the present invention is extremely effective in preventing wound-opening caused by physiological tension, and does not remove the wound-breaking prevention aid. It can be used to treat wounds and surrounding tissues while maintaining the separation prevention function, and can be used regardless of whether the wound is sutured or not sutured. is there.
