Abstract

The utility model relates to a soft tissue and drill head protector for orthopedics. The utility model is characterized in that the utility model comprises an elastic clamp; the front part of a clamping protecting plate at one side of the clamp is fixedly provided with a drill head guiding pipe. When the utility model is used, a steel plate at a bone end is clamped by the elastic clamp, a drill head is inserted in the guiding pipe to work, the drill head can not be broken, and the utility model can prevent soft tissues from being damaged.

Description

Orthopaedics is with soft tissue and bit protector

This utility model relates to the special implement technical field that is used for synthetism.

The current keeping device that in the fracture fixation drilling operation, do not adopt substantially; thereby because lack of skill or careless manipulation cause drill bit to fracture or the phenomenon that injures offside soft tissue and drill bit winding tissue deeply of holing happens occasionally; promptly influence therapeutic effect, increased unnecessary misery to patient again.

The purpose of this utility model is will provide a kind of can protect drill bit not fractureed in the fracture fixation drilling operation and can avoid organizing injury-free keeping device.

The technical solution of the utility model is to include an elasticity folder, and the front portion that presss from both sides backplate in a wherein side of elasticity folder has installing hole, is installed with the drill bit guide pipe on this hole.

The utility model has the advantages that: clamp the epiphysis steel plate during use, the pore that will lead aligns with the steel nail hole, and drill bit inserts and gets final product relieved boring, easy to operate saving time in the guide pipe; The elasticity folder mainly is to injure vital tissue in the time of can avoiding drill bit to penetrate offside cortex except that steel plate is had the fixation; Owing to have the drill bit guide pipe, the drill bit that fractures in the time of can preventing to operate can prevent that again drill bit from twining tissue.Thereby this utility model promptly can increase work efficiency, and can avoid the unnecessary misery of patient again, improves therapeutic effect.

Accompanying drawing shows embodiment of the present utility model, wherein:

Fig. 1 is the perspective view of its user mode;

Fig. 2 is a longitudinal section wherein.

In the embodiment that accompanying drawing provides, the utlity model has one by hinged two folder backplates and be contained in the elasticity folder 1 that the spring 6 on the jointed shaft constitutes, the front portion of wherein a slice folder backplate of elasticity folder 1 has an installing hole, drill bit guide pipe 3 is housed on the installing hole, have external screw thread on the guide pipe 3, its lower end has boss 7, and groove is upwards arranged on the folder backplate of corresponding position, boss 7 position, and the back tightening nut 2 that is installed on the guide pipe 3 is fixed on the folder backplate.1 liang of folder of elasticity folder backplate front portion has the arc-shaped bend that adapts with skeleton 5 shapes, and drill bit 4 inserts work in the guide pipe 3 during use.
