The utility model has the advantages of simple structure and convenient operation. The utility model can stretch and fix a thyroid operation site which is fully exposed.

Description

The thyroid operation self-retractor

This utility model relates to a kind of operating theater instruments, especially a kind of thyroid operation drag hook apparatus.

Hospital does thyroid operation and needs three people at present, operation technique person and assistant and drag hook people, and always with pulling drag hook, the drag hook people did not have the standing place, often need stand on patient's head during the drag hook people need perform the operation, and influenced anaesthetist's work, and the pull-up hook comes inconvenient.

The purpose of this utility model is to design a kind of personnel's drag hook that do not need, and the fixedly thyroid operation position that can stretch automatically fully appears operative site, saves personnel's thyroid operation self-retractor.

The purpose of this utility model is achieved through the following technical solutions: a kind of thyroid operation self-retractor, include drag hook, its special character is, " U " type elasticity that also includes two ends buckle head expands and colludes, the bloated maximum of colluding two arms of " U " type elasticity dilates width and is determined by distance between the hook that is fixed on the bloated fixing head both sides of colluding of elasticity, be fixed with the axis of guide on the fixing head, the axis of guide is parallel with fixing head, be installed with the fastening saddle that can move along its axis on the axis of guide, be installed with movably " L " type drag hook on the saddle post of fastening saddle with center chute and top hook, drag hook can move and rotate along the saddle post, and drag hook can be fixed on the fastening saddle by the locking mother.The two ends gib head that colludes that earlier elasticity expanded during use places the neck line to cut two ends, otch is drawn back up and down appear, and then drag hook is placed thyroid lateral border, with the throat muscle group laterally, go up outward, outer inferior any direction draws back, and thyroid is fully appeared.

" L " type drag hook can be improved to Type, two ends are respectively equipped with the different hook of length, and the two ends hook is used in different transposings according to the thyroid depth.

The hook top of drag hook and the elasticity gib head top collude of expanding all tilts to draw direction, so that stable when stretching, does not slide.

The thyroid self-retractor of this utility model design is simple in structure, and the user makes, and the fixedly thyroid operation position that just can stretch of need not choosing fully appears operative site, also applicable different depth thyroid, and also can making stretches stablizes, and does not slide.

Accompanying drawing and drawing explanation:

Fig. 1: this utility model most preferred embodiment front view;

The A-A cutaway view of Fig. 2: Fig. 1;

Fig. 3: the side view of drag hook 1 in the most preferred embodiment.

Among the figure: 1 drag hook, 2 elasticity expand and collude, 3 gib heads, and 4 arms, 5 fixing heads, 6 hooks, 7 lockings are female, 8 axis of guides, 9 fastening saddles, 10 saddle posts, 11 chutes, 12 hooks.

Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying this utility model.

With reference to figure 1, Fig. 2, Fig. 3.The fixing head 5 that two ends are provided with hook 6 is fixed on " U " type elasticity by rivet and expands and collude 2 top, the elasticity that is stuck in two hooks 6 expands and to collude on 2 two arms 4, the width that dilates of two arms 4 is limited by the spacing of two hooks 6, the axis of guide 8 is horizontally fixed on the fixing head 5 by the fixed leg at two ends, being through fastening saddle 9 on the axis of guide 8 can drive drag hook 1 and move axially along the axis of guide, drag hook 1 center that two ends are respectively equipped with the different hook of length 12 has chute 11, be tightened on the saddle post of fastening saddle 9 by locking female 7, the hook top of drag hook 1 and elasticity expand and collude 2 gib head top and all tilt to draw direction.All parts of this utility model are all made by rustless steel, and fineness, rust-preventing characteristic are good.
