Abstract
The utility model relates to a compression and protective rib reconstruction type metal bone plate, which is provided with a body and clamping jaws. The body and the clamping jaws are made of pure titanium. Four evenly spaced holes arranged on the body are all screw locking holes, and a compression screw is mounted in each screw locking hole. The top face of each compression screw is lower than the top face of the body or level to that of the body. The upper portion of each screw locking hole is semispherical, and the top of each compression screw can be embedded into the semispherical upper portion of the corresponding screw locking hole, or the upper portion of each screw locking hole is conical while the top of each compression screw can be embedded into the conical upper portion of the corresponding screw locking hole. No needle guide hole for temporary fixation is needed on the compression and protective rib reconstruction type metal bone plate, and thereby the step of temporary fixation is omitted, the metal bone plate is not easy to slip or shift, and foreign body sensation of a human body about an implant is reduced.
Description
Technical field
This utility model relates to a kind of medical implant, especially a kind of pressurization and protectiveness rib reconstruction type metal bone fracture plate.
Background technology
Blade plate is the implant of fixedly orthopaedics commonly used in the medical treatment, existing fracture bone plate, the operated by rotary motion guide pinhole is used for interim location on the mainboard, but does not have the corresponding measure that can fix and pin, only depends on holding claw to embrace rib usually and realizes that the butt joint of rib fixes.This traditional docking mode deficient in stability is easy to take place slippage and displacement, thereby causes operative failure, increases patient's misery.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of pressurization and protectiveness rib reconstruction type metal bone fracture plate are provided, make the butt joint of rib firm, reduce patient's foreign body sensation simultaneously.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of pressurization and protectiveness rib reconstruction type metal bone fracture plate; have main body and holding claw; have at least 2 holes on the described main body; the hole that has on the main body all is the screw lock hole, in the screw lock hole forcing screw is installed.
Further, have 4 evenly spaced holes on the described main body, 4 holes that have on the main body all are the screw lock hole.
Further, the top of described screw lock hole is hemispherical, and the bottom of described screw lock hole is a cylindricality, and described forcing screw top is for embedding the half sphere shape on screw lock hole top.
Further, the top of described screw lock hole is taper, and the bottom of described screw lock hole is a cylindricality, and described forcing screw top is for embedding the bullet on screw lock hole top.
Further, the taper position of described screw lock hole has screw thread, and the bullet at described forcing screw top has respective threads.
Further, it is equal with the main body end face that the end face of described forcing screw is lower than the end face of the end face of main body or forcing screw.
Further, described main body and holding claw are made by pure titanium.
The beneficial effects of the utility model are: the hole that has on the main body of the present utility model all is the screw lock hole, does not need to be used for temporary fixed guide pinhole, has saved temporary fixed step.Forcing screw is positioned at the screw lock hole, screws in the skeleton part of butt joint, makes firm being fixed on the skeleton of blade plate, is difficult for slippage, displacement.Screw lock hole top is hemispherical or taper, and the top of forcing screw is better embedded, and forcing screw is not protruded in body surfaces, reduces the foreign body sensation of human body to implant.Main body of the present utility model and holding claw adopt pure titanium to make, and plasticity is good, does not contain iron ion, breast CT, MRI are checked do not have influence, histocompatibility is good, as does not have the taking-up of needn't performing the operation once more of special discomfort.

The specific embodiment
In conjunction with the accompanying drawings this utility model is further described now.The sketch map that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with this utility model.
As shown in Figure 1, a kind of pressurization and protectiveness rib reconstruction type metal bone fracture plate have main body 1 and holding claw, and main body 1 and holding claw are made by pure titanium.Have 4 evenly spaced holes on the main body 1,4 holes that have on the main body all are screw lock hole 2, and forcing screw 3 is installed in the screw lock hole 2.It is equal with main body 1 end face that the end face of forcing screw 3 is lower than the end face of the end face of main body 1 or forcing screw 3.
Shown in Figure 4 as Fig. 2 Fig. 3, embodiment one: the top of screw lock hole 2 is hemispherical, and the bottom of screw lock hole 2 is a cylindricality, and forcing screw 3 tops are for embedding the half sphere shape on screw lock hole 2 tops.
Shown in Figure 6 as Fig. 5, embodiment two, and the top of screw lock hole 2 is taper, and the bottom of screw lock hole 2 is a cylindricality, and forcing screw 3 tops are for embedding the bullet on screw lock hole 2 tops.The taper position of screw lock hole 2 has screw thread, and the bullet at forcing screw 3 tops has respective threads.
The hole that has on the main body 1 of the present utility model all is a screw lock hole 2, does not need to be used for temporary fixed guide pinhole, has saved temporary fixed step.Forcing screw 3 is positioned at screw lock hole 2, screws in the skeleton part of butt joint, makes firm being fixed on the skeleton of blade plate, is difficult for slippage, displacement.Screw lock hole 2 tops are hemispherical or taper, and the top of forcing screw 3 is better embedded, and forcing screw 3 is not protruded in body surfaces, reduce the foreign body sensation of human body to implant.
Main body 1 of the present utility model and holding claw adopt pure titanium to make, and plasticity is good, does not contain iron ion, breast CT, MRI are checked do not have influence, histocompatibility is good, as does not have the taking-up of needn't performing the operation once more of special discomfort.
This utility model is applicable to the single-shot or the fracture of multiple ribs of obvious dislocation, also can be used for out the butt joint of the disconnected rib posterior rib of breast.Use concrete operation method of the present utility model to be: to cut periosteum, fracture para-position, steel plate is fixing and forcing screw is fixed, can repeatedly rebuild, sew up periosteum according to clinical.This utility model need not operation and takes out.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the description, must determine its technical scope according to the claim scope.
