Abstract

The utility model discloses a localizer for removing the plate-screw fixation. At one end of the bar-type handle of the localizer is a hollow cylinder and at the other end is a groove that has a strip hole and that corresponds to the inside recess of the work surface. Both ends of the handle have bending parts relative to the center which are parallel to each other. The cylinder and groove are arranged on the bending part. The utility model solves the problem of removing the internal plate-screw fixation for the second time after the fracture healing. If the problem is foreseen in the second removal of the plate-screw fixation, then after the plate and screw on the bone have become visible, in the light of the plate width, the hole arrangement and the height of the visible part of the screw tail, placing the hollow cylinder over the screw tail or directing the groove ed toward the screw tail to hold the plate, and then drilling and grinding the screw tail with the drill until it becomes flat. In this way, the plate can be removed.

Description

Get the steel plate screw localizer

Technical field

This utility model relates to a kind of medical apparatus and instruments, and especially a kind of orthopaedics is used gets the steel plate screw localizer.

Background technology

Clinically, after the union of fracture, when secondary is got the internal fixation steel plate screw, in the art long run into because of the internal fixation time of a specified duration excessively, growth of spur and fracture end are constantly moulding, occur screw twist motionless, can not get, or skid in screw head of a nail groove because of misoperation causes screwdriver, operation is fallen into a dilemma, have to use aids such as brill, cutter, hammer temporarily, both prolong operating time, increased the patient suffering again.

Summary of the invention

The technical problems to be solved in the utility model is to get the reality that the internal fixation steel plate screw is difficult to take out at secondary clinically, and a kind of steel plate screw localizer of getting is provided, to shorten operating time, minimizing person's misery.

For solving the problems of the technologies described above, the utlity model has the strip handle, an end of handle is provided with the cylinder with cylindrical hollow inner chamber, and the relative other end is provided with the groove with respect to the work surface indent, is provided with strip hole in this groove.

The both ends of described handle have bending part with respect to the handle stage casing, two bending part opposing parallel, and described cylinder and groove are on the relative bending part.

After adopting said structure, when running into secondary and get the internal fixation steel plate screw and be difficult to take out, after the steel plate on the skeleton, screw appear, according to steel plate width, arrange in the nail hole and the screw afterbody appears height, the cylinder that will have a cylindrical hollow inner chamber is enclosed within the screw afterbody or concave part is aimed at the screw afterbody block steel plate, with bit drills mill screw afterbody, until its afterbody is polished, steel plate can take out, it is simple to operate, and can shorten operating time, minimizing person's misery.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

The structural representation that Fig. 2 overlooks for Fig. 1.

The specific embodiment

With reference to accompanying drawing, this is got the steel plate screw localizer and has strip handle 1, and an end of handle 1 is provided with the cylinder 3 with cylindrical hollow inner chamber 4, and the relative other end is provided with the groove 2 with respect to the work surface indent, is provided with strip hole 5 in this groove 2.The both ends of handle 1 have bending part with respect to the handle stage casing, two bending part opposing parallel, and described cylinder 3 and groove 2 are on the relative bending part, and the stage casing is a hand grip portion.This localizer has two kinds of user modes, the screw afterbody of using when fixation steel plate exposes the steel plate plane, and when can not getting with screwdriver, the cylinder 3 that will have cylindrical hollow inner chamber 4 is enclosed within the screw afterbody, bore mill screw afterbody with special drill bit by cylindrical hollow inner chamber 4, until its afterbody is polished, steel plate can take out; And the screw afterbody of using when fixation steel plate does not expose the steel plate plane, and when can not getting with screwdriver, concave part is aimed at the screw afterbody and blocked steel plate, bores mill screw afterbodys with drill bit by strip hole 5, and until its afterbody is polished, steel plate can take out.After this apparatus had thoroughly solved union of fracture, secondary was got the difficult problem that the internal fixation steel plate screw is difficult to take out.

Claims (2)

1, a kind of steel plate screw localizer of getting, it is characterized in that it has strip handle (1), one end of handle (1) is provided with the cylinder (3) with cylindrical hollow inner chamber (4), and the relative other end is provided with respect to the groove of work surface indent (2), is provided with strip hole (5) in this groove (2).

2, the steel plate screw localizer of getting according to claim 1 is characterized in that the both ends of described handle (1) have bending part with respect to the handle stage casing, two bending part opposing parallel, and described cylinder (3) and groove (2) are on the relative bending part.
