Abstract

The utility model discloses a chamber is thyroid gland drag hook for mirror, which comprises a body, hook rod has been inserted to body inner chamber one end, and the body other end has a drag hook head through the pivot is articulated, connect through the connecting rod between hook rod and the drag hook head, hook rod middle part is equipped with the shell fragment, and the hook rod top is equipped with the handle, the body side corresponds the shell fragment position and is equipped with the extrusion piece, the body top is equipped with the recess that matches with the drag hook head, this thyroid gland drag hook passes through hook rod and the connecting rod can make drag hook head free rotation, in the time will performing the operation can the drag hook head draw put the recess into in, avoid the drag hook head outside the fish tail human, release the drag hook head when the drag hook to the assigned position, and the drag hook head skids for the S type prevents the drag hook head, the better performs the operation, and the drag hook top prevents for smooth curved surface that the fish tail is human, the shell fragment can carry out limiting displacement to the drag hook head, the turning apparatus is simple in structure, high durability and convenient use.

Description

A kind of endoscopic thyroid retractor

Technical field

This utility model relates to field of mechanical technique, is specially a kind of endoscopic thyroid retractor.

Background technology

In human thyroglobulin resection operation, after being separated between thyroid with tissue, must be pulled upwardly lesions position, can excision be carried out, need high accuracy and high-level specific purpose tool, in the prior art, retractor head surface is shiny surface, easy landing, operation trouble, and retractor head expansion increases outside and the contact area of human skin easily scratches human body, can not meet desirable surgical effect.

Utility model content

The purpose of this utility model is to provide a kind of endoscopic thyroid retractor, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme: a kind of endoscopic thyroid retractor, comprise body, described chamber body one end is inserted with drag hook bar, and the body other end is hinged with retractor head by rotating shaft, the shape of described retractor head is S type, connected by connecting rod between the end of described drag hook bar and retractor head, shell fragment is provided with in the middle part of described drag hook bar, described body leaves the groove for engaging shell fragment, and respective slot position is provided with crushing block on body, described drag hook masthead portion is provided with hands handle, described bodies top is provided with the groove mated with retractor head.

Preferably, described bodies top shape is smooth surface type.

Preferably, described handle surfaces cover has anti-slip rubber.

Preferably, described crushing block has elasticity.

Compared with prior art, the beneficial effects of the utility model are: this goitre retractor can make retractor head freely rotate by drag hook bar and connecting rod, can retractor head pulling enter in groove when performing the operation, retractor head is avoided to scratch human body outside, when drag hook releases retractor head again to assigned address, and retractor head is S type prevents retractor head from skidding, increasing friction force, better perform the operation, and drag hook top is smooth surface prevent scratch human body, shell fragment can carry out position-limiting action to retractor head, and this utility model structure is simple, easy to use.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation;

Fig. 2 is that retractor head is positioned at body figure.

In figure: 1 body, 2 drag hook bars, 3 retractor heads, 4 handles, 5 shell fragments, 6 crushing blocks, 7 connecting rods, 8 rotating shafts, 9 grooves.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.

Refer to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of endoscopic thyroid retractor, comprise body 1, body 1 top shape is smooth surface type, described body 1 inner chamber one end is inserted with drag hook bar 2, and body 1 other end is hinged with retractor head 3 by rotating shaft 8, the shape of retractor head 3 is S type, connected by connecting rod 7 between described drag hook bar 2 and retractor head 3, shell fragment 5 is provided with in the middle part of described drag hook bar 2, and drag hook bar 2 top is provided with handle 4, handle 4 surface cover has anti-slip rubber, corresponding shell fragment 5 position, described body 1 side is provided with crushing block 6, crushing block 6 has elasticity, described body 1 top is provided with the groove 9 mated with retractor head 3, this goitre retractor is coordinated by drag hook bar 2 and connecting rod 7 can make retractor head 3 freely rotate, can retractor head 3 pulling enter in groove 9 when performing the operation, retractor head 3 is avoided to scratch human body outside, when drag hook is releasing retractor head 3 to assigned address, the opening and closing angle of retractor head 3 is 90 degree to the maximum, and retractor head 3 prevents retractor head 3 from skidding for S type, increasing friction force, better carry out hands art, and drag hook top is smooth surface prevent scratch human body, shell fragment 5 can be fixed effect to retractor head 3, this utility model structure is simple, easy to use.

Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
