CN201431502Y - Double-end steel needle - Google Patents

Abstract

The utility model discloses a double-end steel needle, comprising a sharp point. On the basis of traditional steel needles, the needle end is changed into the sharp point, thus changing the needle into a double-end steel needle; when in operation, the steel needle does not need to be pulled out and turned, and another sharp point is directly used to drill through fracture end at another side, thushaving convenient operation and avoiding unstable fixation caused by pulling out the steel needle repeatedly.

Description

The double end draw point

Technical field

This utility model relates to the orthopaedics fixed apparatus, directly relates to the double end draw point.

Background technology

At present, traditional orthopaedics draw point only one be sharp point, in actual operation, at first drive in the wrong direction to bore saturating side of fracture end from fracture site with sharp sharp one, then draw point is extracted, turn draw point, allow the draw point afterbody get out along boring good bone road, after the reduction of the fracture draw point again direct motion bore the opposite side fracture end, operate loaded down with trivial details like this, draw point is easily loosening, influences fixed effect.

Summary of the invention

The purpose of this utility model will provide a kind of double end draw point exactly, and it is loaded down with trivial details that it can overcome existing operation effectively, the problem that draw point is easily loosening.

The purpose of this utility model is achieved in that on the basis of traditional draw point, make backshank into sharp point, make it become the sharp sharp draw point of double end, when undergoing surgery, just there is no need again draw point to be extracted and turned draw point, and directly use the saturating opposite side fracture end of another sharp pointed drill, and easy and simple to handle, avoided the invar pin to extract the fixedly shakiness that causes back and forth.

Description of drawings

Accompanying drawing is a structure principle chart of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

Accompanying drawing shows structure of the present utility model, have sharp sharp 1, on the basis of traditional draw point, backshank is made into sharp sharp 1, make it become the double end draw point, when undergoing surgery, just there is no need again draw point to be extracted and turned draw point, and directly with the saturating opposite side fracture end of another sharp sharp 1 brill, easy and simple to handle, avoided the invar pin to extract the fixedly shakiness that causes back and forth.

Claims (1)

1. A kind of double end draw point is characterized in that: have sharp point (1), make traditional draw point backshank into sharp point (1), make it become the double end draw point.
