Abstract

The utility model relates to a clamp type tetragonal retractor for medical use, which is characterized in that a pull opening part is composed of a forward hook, a rear drag hook, a left division hook, and a right division hook which are hinged together by a hinged shaft. Meanwhile, the four hooks are vertically provided with hook poles. When a left clamp handle and a right clamp handle are divided, the four hooks and the vertical hook poles arranged on the four hooks meet through the function of a transmission connecting rod part. Then, the utility model is put into an operative incision, and the left and the right clamp handles are closed. Thus, the operative incision is pulled and opened by the four hooks and the back and forth, and the left and right of the hook poles thereof. The purpose of favorable exposure of the field of view of operations is achieved.

Description

Jaw type four directions retractor

This utility model relates to a kind of medical apparatus and instruments, the perform an operation jaw type four directions retractor of usefulness of particularly a kind of doctor.

At present, the surgeon of medical departments such as hospital particularly does appendectomy when performing an operation, do the Maxwell otch usually, we know, the Maxwell otch needs obliquus internus abdominis m., transversus abdominis m. is staggered cuts, and two flesh hooks of minimum use just can be exempted from strong the expansion and be opened otch, also need assistant and drag hook in addition, can not reach good art open country appears like this, and occupations of land side such as the other assistant's drag hook of operating-table, use is inconvenient, wastes time and energy.Medical department presses for a kind of art open country and appears good operation pull device or apparatus for this reason.

This utility model improves at the problem that prior art exists, design a kind of simple in structure, the side of occupation of land, processing easily, cost is low, and is easy to use, has the jaw type four directions retractor that good art open country appears.

This utility model is achieved by following manner: a kind of jaw type four directions retractor, comprise pincers retracting partly and the kinematic link part part and front end thereof, it is characterized in that: the said part that retracts pushes away hook before hinged by hinge, back drag hook, part hook on the left side and part hook on the right side and constitute, wherein, before push away hook first half for semicircle and vertical hook post is set in its end, before push away hook latter half of for straight-bar and chute is set thereon, back drag hook is a straight-bar, its end and straight-bar surface are respectively equipped with vertical hook post and chute, but above-mentioned said hinge pro-pushes away the relative slip of the interior do of chute of hook and back drag hook, a left side, part the hook first half on the right side and be the quadrant arc and vertical hook post, a left side are set respectively in their end, part the latter half of of hook on the right side for clamping part and being called a left side, right pincers handle.Said kinematic link partly is to be made of a pair of symmetrically arranged front rod up and down and a pair of symmetrically arranged back link up and down, wherein, the front end of a pair of front rod can be hinged with the rear end that before pushes away hook by hinge, and this hinge can be done relative slip in the chute of back drag hook, and the front end of the rear end of this a pair of front rod and a pair of back link respectively by hinge and left and right pincers in the middle of the place hinged, the end of a pair of back link terminal hinged by hinge and back drag hook simultaneously.Here owing to before push away hook, back drag hook, part hook on the left side and the hook post that parts on the right side on the hook is vertically disposed; and pincers are part that left and right pincers handle is when closing; pushing away hook before can promoting by a pair of front rod moves forward; the road is crossed a pair of back link and is pulled back the back drag hook and move backward; simultaneously; clamp arching trajectory slip with left and right for left and right minute hook of one will be distinguished downwards, the top is oblique; until opening; form the state that the upper and lower, left and right four direction retracts; when divided pincers the time, then opposite with said process.

This utility model is compared with prior art, has simple in structurely, easy to use, has characteristics such as good art open country appears, and this technology has and do not take up an area of the side simultaneously, processing easily, characteristics such as cost is low, and is easy to utilize.

Fig. 1 is the overall construction drawing of this utility model when the pincers handle closes.

Fig. 2 is that this utility model is clamping the overall construction drawing after opening.

Among the figure: push away hook, 2 back drag hooks, 3 before 1 and part hook, 4 hinges, 5 hinges, 6 front rods, 7 back links, 8 hinges, 9 right pincers on the right side, 10 left side pincers handles, 11 hinges, 12 chutes, 13 are parted on the left side hook, 14 hook posts, 15 chutes.

Most preferred embodiment of the present utility model is shown in Fig. 1-2.A kind of jaw type four directions retractor, comprise pincers retracting partly and the kinematic link part part and front end thereof, it is characterized in that: the said part that retracts pushes away hook 1 before hinged by hinge 4, back drag hook 2, part hook 13 on the left side and part hook 3 on the right side and constitute, wherein, before push away hook 1 first half for semicircle and vertical hook post 14 is set in its end, before push away hook 1 latter half of for straight-bar and chute 12 is set thereon, back drag hook 2 is a straight-bar, its end and straight-bar surface are respectively equipped with vertical hook post 14 and chute 15, but above-mentioned said hinge 4 pro-push away the relative slip of chute 15 interior dos of hook 1 and back drag hook 2, a left side, part hook 13 on the right side, 3 first halfs are the quadrant arc and in their end vertical hook post 14, a left side are set respectively, part the latter half of of hook on the right side for clamping part and being called a left side, right pincers are 9,10.Said kinematic link partly is to be made of a pair of symmetrically arranged front rod 6 up and down and a pair of symmetrically arranged back link 7 up and down, wherein, the front end of a pair of front rod 6 can be hinged with the rear end that before pushes away hook 1 by hinge 5, and this hinge 5 can be done relative slip in the chute 15 of back drag hook 2, and the front end of the rear end of this a pair of front rod 6 and a pair of back link 7 is hinged place in the middle of 9,10 by hinge 11 and left and right pincers respectively, simultaneously the end of a pair of back link 7 by hinge 8 with after drag hook 2 terminal hinged.Here owing to before push away hook 1; back drag hook 2; the hook post 14 that parts hook 13 on the left side and part on the right side on the hook 3 is vertically disposed; and pincers are promptly left part; right pincers are 9; 10 when closing; pushing away hook 1 before can promoting by a pair of front rod 6 moves forward; pulling back back drag hook 2 by a pair of back link 7 moves backward; simultaneously; with a left side; right pincers are 10; 9 is the left side of one; part hook 13 on the right side; 3 will distinguish downwards; the oblique arching trajectory in top slides; until opening; in the formation; down; a left side; the state that right four direction retracts; when separately left; right pincers are 10; 9 o'clock, then opposite with said process.

Present technique in use can be used the formaldehyde fumigation sterilization, autoclaving and boiling sterilization.Draw back left and right pincers 10,9 o'clock, before push away hook 1, back drag hook 2, part hook 13 on the left side, the hook end that parts hook 3 on the right side injects in the otch after closing up together, when the left and right pincers of closure 10,9 the time, above-mentioned four hooks 1,2,13,3 retract operative incision forwards, backwards, this moment, scalable hinge 4 (this hinge 4 is threaded rotatable fixing) can be fixed.After finishing using, lubricate with aqueous paraffin wax cleaning, dry back.When present technique is specifically made, can be made into large, medium and small all size, to satisfy instructions for use.
