Abstract

The utility model discloses a thyroid operation pull hook fixer. The fixer comprises a pull hook and also comprises a U-shaped elastic expanding hook with hook heads at two ends, and the maximum dilation width of two arms of the U-shaped elastic expanding hook is determined by the distance between bent hooks at both sides of a fixed plate fixed on the elastic expanding hook. A guiding shaft is fixed on the fixed plate and is parallel to the fixed plate, and a buckling saddle which can move along the axial direction is penetrated on the guiding shaft. An L-shaped pull hook which can move and has a center sliding groove and a hook at the top end is penetrated on a saddle post of the buckling saddle, and the pull hook can move and rotate along the saddle post and can be fixed on the buckling saddle through a locking nut. Because a structure is used, the pull hook fixer has the advantages of simple structure and convenient use, and the operative position of thyroid can be stretched and fixed with no need of persons to sufficiently expose operative visual field.

Description

The thyroid operation retractor holder

Technical field

This utility model relates to a kind of thyroid operation apparatus, belongs to the surgery medical surgical instrument.

Background technology

At present, when implementing thyroid operation, the exposure of the operation of operation and art open country often needs three, four-player, comprises patient's operation, and each drag hook of leaning to one side a side of a plurality of assistant, and patient's skin of neck and muscle are drawn back, and is convenient to that art is wild to be exposed.This method not only wastes time and energy, and the art open country appears weak effect, hinders operation technique.

Summary of the invention

The purpose of this utility model is to realize like this, this thyroid operation retractor holder includes drag hook, " 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.Earlier place the neck line to cut two ends the two ends gib head of flexible expansion hook during use, otch drawn back up and down appear, then pull 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 " Z " type, and 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.

Because adopt said structure, this retractor holder is simple in structure, and is easy to use, the fixedly thyroid operation position that can stretch of need not choosing fully appears the art open country.
