RU194086U1 - DEVICE FOR CLOSING THE REGIONS OF THE RAS - Google Patents

Abstract

The utility model relates to medical equipment and is designed to bring the edges of wounds closer for temporary closure of incisions and open wounds during surgical operations. The device consists of miniature pneumatic clamps that clamp tissue by pressing between the clip-clip and the base. Compression is carried out by shifting the clip-clamps when applying compressed air to the pneumatic clamp cylinder. The compression force is controlled by changing the pressure of the supplied air. Air is supplied to the pneumatic clamp via pipes from the pneumatic distributor and mini-compressor. The air supply process is controlled by the controller. While the wound is closed, cyclic release and clamping of the pneumatic clamps is performed alternately, in order to avoid prolonged clamping of tissues. Such cyclic work is carried out using a control microcontroller that controls the operation of the device according to the cycle set by the medical staff.

Description

The device relates to medical equipment and is designed to bring the edges of the wounds to temporarily close the incisions and open wounds during surgical operations.

A device for rapprochement of wounds No. 2257861 is known, which is structurally closest to this device.

The device contains a gear rack with pressure plates, a ratchet mechanism with a handle and fixing movable branches, which are installed in the same plane as the pressure plates and are equipped with spikes with a tread-drain.

The disadvantage of this device is that when piercing tissues with spikes, they are injured, resulting in a high probability of infection of the wound.

The device (Fig. 1) consists of pneumatic clamps (clamping mechanism) with hooks, clasps, pneumotubes and a control unit.

The control unit (Fig. 1) includes a filter 1, a compressor 2, a controller 3 and a pneumatic distributor 4.

Pneumatic clamp (Fig. 2) consists of a base 5, clip-brackets 6, extendable rod 7, pneumatic cylinder 8.

In FIG. 3 pneumatic clamps are shown in the position when the edges of the wounds are tightened.

In FIG. 4 shows the position of the pneumatic clamps when the edges of the wounds are apart.

A general view of one pneumatic clamp in the expanded state is shown in FIG. 5.

In FIG. 6 shows the connection of two opposed pneumatic clamps.

The operation of the device can be divided into three stages:

1) Pneumatic clamps are superimposed on the edges of the wound incision in a row and strictly opposite each other. Their number is determined by the size of the wound and should be paired.

Tissues at the edges of the wound should be between the clip-clamp and the base of the pneumatic clamp.

Compression is carried out by shifting the clip-clamps when applying compressed air to the pneumatic clamp cylinder.

The air supply is carried out as follows: air is drawn in from the atmosphere, passes through the filter and enters the compressor, from where it is pumped into the pneumatic distributor and, then, is supplied through the pipes to the pneumatic clamp.

The compression force is controlled by changing the pressure of the supplied air. The air supply process is controlled by the Controller.

2) Pneumatic clamps, located opposite each other, come together manually and they are engaged with each other using hooks that can be rotated around its axis. Thus, temporary closure of the wound after surgical treatment is carried out.

3) While the wound is closed, cyclic release and clamping of the pneumatic clamps is performed alternately, in order to avoid prolonged clamping of tissues, i.e. if even numbers are clamped, then odd numbers are released and vice versa.

Such cyclic operation is ensured by means of a control microcontroller, which controls the operation of the device according to a cycle set by the medical staff.

The main controlled parameters of the device are the pressure of the supplied air and the time of alternating (cyclic) clamping of the pneumatic clamps.

The technical task is to eliminate tissue trauma and expand the functionality of the device.

The technical result is achieved by the fact that the task of rapprochement / dilution of the edges of the wounds is performed by pneumatic clamps and the compression force is controlled by changing the pressure of the supplied air.

Claims (1)

A device for converging the edges of the wounds, characterized in that it consists of a base, a controller, pneumatic clamps containing a pneumatic cylinder, and clip-brackets, while the pneumatic clamps clamp the tissue by pressing them between the clip-clamp and the base, made with the possibility of shifting the clip-bracket during feeding compressed air to the pneumatic clamp cylinder and adjust the compression force by changing the pressure of the supplied air, while the controller serves to control the air supply process.
