Description

Automatic plate dentation drag hook

This utility model design orthopaedics medical apparatus and instruments, particularly a kind of automatic plate dentation drag hook.

In the spinal surgical procedure, in order to appear the art open country, often need in the prior art both sides paraspinal muscle to be retracted with common dentation drag hook, but in the process of retracting, because drag hook tension force is bigger, thus part muscular tissue promptly extrude by between cog because present dentation drag hook and muscle contact surface is less, often cause part muscular tissue to be dampened, and the muscular tissue extruded of between cog take up room and make appearing of operating field be subjected to certain restriction.

The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, to organize not damaged, operating field to expose good automatic plate dentation drag hook and provide a kind of to retracting.

The purpose of this utility model is achieved in that it comprises scissor drag hook main body, and jump ring is equipped with in two handgrip positions of this main body, and cutter shape hook plate is equipped with by rotating shaft in the cutter hub position of this main body, and this hook plate bottom is provided with briar tooth.

This utility model proves through clinical practice, have simple in structure, easy to operate, organize not damaged, operating field to expose advantages such as good to retracting, be the desirable apparatus of spinal operation.

The explanation of accompanying drawing drawing:

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

Below in conjunction with drawings and Examples in detail this utility model is described in detail.

Its drag hook main body 1 shape of this utility model is scissor, and jump ring 5 is equipped with in two handgrip positions of this main body 1, and cutter shape hook plate 3 is equipped with by rotating shaft 2 in the cutter hub position of this main body 1, and these hook plate 3 bottoms are provided with briar tooth 4.

Cutter shape hook plate of the present utility model 3 is big with the contact area of muscle, and the muscular tissue pressurized is even, can guarantee that muscular tissue do not have skin ulcer and retracted, and the briar tooth 4 that its bottom is provided with can the fine fixing muscular tissue that is retracted, and prevents that it from skidding off.
