Abstract
The utility model relates to a reticulation metal plate to restore the skull damage. The metal connections between nodes are in form of arc, a screw hole is arranged on each node, during the operation, 3D shaping of the reticulation metal plate can be easily carried out in accordance with the curve of the skull of the patient, at the same time, the reticulation metal plate can be easily cut in accordance with the injury area of the patient.
Description
Technical field
This utility model relates to a kind of net-shaped metal plate that is used to repair head injury.
Technical background
In the neurocranial surgery operation, often need to use a kind of expanded metal that injured even the damaged skull of part are repaired.At present used expanded metal pass adopts circle, rhombus, rectangle and square etc. usually, and the arrangement in its hole also majority is rhombus or rectangle.The expanded metal of above-mentioned form in use has a common defective, difficulty relatively when promptly carrying out three-D plastic according to patient's cranium type in the operation, especially required curved surface camber bent when big or the area of required covering when big expanded metal often present rough fold and influence repairing effect, the reason of its terms of mechanics is that the pass of rule adds that the arrangement of rule causes expanded metal to cause in that the bending stiffness that is subjected to all directions under the situation of moment of flexure is inconsistent.
Summary of the invention
The purpose of this utility model provides a kind of net-shaped metal plate that skull is repaired that is used for, and this net-shaped metal plate all directions bending stiffness no significant difference can carry out three-D plastic very easily.
The technical scheme that realizes above-mentioned purpose is, the metal connecting portion between each node of net-shaped metal plate described in the utility model is curved, and its curved metal connecting portion and each two internodal straight line connecting line do not coincide, and is multidirectional radial arrangement.This net-shaped metal plate all directions bending stiffness no significant difference, each curved metal connecting portion be subjected to will taking place when external force produces distortion on the three-dimensional bending, reverse and warpage.Experiment showed, that to adopt the net-shaped metal plate of curved metal connecting portion non-directional when carrying out three-D plastic, operate easy and conveniently, can carry out suitable choice according to the size of damaged area and cut out, can meet the needs of skull prosthesis preferably.
Description of drawings
Fig. 1 is used to repair the net-shaped metal plate sketch map of skull for this utility model,
Fig. 2 is this utility model embodiment sketch map,
Fig. 3 is another embodiment sketch map of this utility model,
Fig. 4 is the another embodiment sketch map of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, net-shaped metal plate of the present utility model (1) is to be made by the metal material that is suitable for implant into body, for example rustless steel, titanium or titanium alloy etc., the thickness of metallic plate (1) is usually between 0.1mm～5mm, the intersection point of each mesh is node (2), coupling part between each node is arc connecting portion (3), is provided with screw hole (4) for conveniently being fixed on part or all of node place in the practicality, and the thin straight line among the figure is that theory is subjected to the line of force (5) between node.
As shown in Figure 1, its basic characteristics of net-shaped metal plate of the present utility model (1) are to be connected by arc connecting portion (3) between each node (2), be subjected to the time spent of doing of moulding external force when net-shaped metal plate (1), each node (2) will produce space displacement under external force, because the theory between each arc connecting portion (3) and node (2) is not coincided by the line of force (5), therefore arc connecting portion (3) will produce bending, reverse the deformation with various ways such as warpage, and this deformation does not have tangible directivity; The deformation of the multiple class of arc connecting portion (3) makes the space length between two nodes (2) can not be subjected to other joint constraint in addition, therefore net-shaped metal plate (1) can be comparatively easily become required curve form and can not produce the fold that is difficult to eliminate by moulding, as Fig. 2, Fig. 3, Fig. 4, shown in, locate to be provided with at the node (2) of net-shaped metal plate (1) according to the needs of operation and be exclusively used in the screw hole (4) that passes hold-down screw, this not only can guarantee the fastening effective of screw, the stress concentration of also having been avoided node (2) to locate simultaneously.
Claims (3)
1. net-shaped metal plate that is used to repair head injury, its basic feature is this net-shaped metal plate (1) by offering some holes with given shape on the plate-shape metal material of body implant requirement and form meeting, metal joint between some adjacent holes forms node (2), and the thickness of this net-shaped metal plate (1) is usually between 0.1mm～5mm.
2. the net-shaped metal plate that is used to repair head injury as claimed in claim 1, its basic feature are that the connecting portion between each adjacent node (2) is curved, and each node (2) has at least an arc connecting portion (3) to be connected with adjacent node.
3. the net-shaped metal plate that is used to repair head injury as claimed in claim 1, its basic feature are to locate to be provided with screw hole (4) at part or all of node (2) to be screwed in order to making as required.
