Abstract
The utility model discloses a kind of hip joint self-retractor structure, include the spring steel of an overall U-shaped, be connected to two drag hooks near position, both ends on spring steel by screw symmetry; Described drag hook includes the neck of hook portion of an obtuse angle shape and is integrally connected to the hook body segment of end, one end, neck of hook portion; Described neck of hook portion forms connecting hole away from the support arm of hook body segment, and described screw is connected with the screw on spring steel through after connecting hole, and the position described spring steel offering screw forms the recess holding neck of hook portion; The support arm that described neck of hook portion is connected with hook body segment is connected with pipe joint, on drag hook from pipe joint to the hollow pipe structure of the part of hook body segment bottom for being connected.This drag hook only needs an assistant just can operate, and described connecting hole is convenient to adjust distance between two drag hooks according to practical situation, to adjust the size of surgical field of view, and can be blotted in time only in the blood and slime in operation process, the broken end of bone etc. in time.
Description
Technical field
This utility model belongs to bone surgery apparatus field, is specifically related to the structure of hip joint drag hook.
Background technology
Carry out artificial total hip arthroplasty at present clinically when exposure hip joint, generally use Huffman drag hook clinically at present, auxiliary with S drag hook, Huffman drag hook coordinates the feature of S drag hook to be need the doctor's number participating in operation more.General needs 1 operating doctor and 3 assistants could complete operation smoothly.So invent a kind of drag hook for artificial full hip-joint replacement operation particular design, both conveniently can appear surgical field of view, and also can reduce assistant's number, be the hope of joint surgery doctor.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, a kind of hip joint drag hook of new structure is provided, is beneficial to appear surgical field of view, reduce assistant and participate in number, facilitate joint surgery doctor to manipulate, be beneficial to the carrying out of hip replacement surgery.
For realizing the object of this utility model, being achieved by the following technical solutions: a kind of hip joint self-retractor structure, includes the spring steel of an overall U-shaped, being connected to two drag hooks near position, both ends on spring steel by screw symmetry; Described drag hook includes the neck of hook portion of an obtuse angle shape and is integrally connected to a hook body segment of end, one end, neck of hook portion; Described neck of hook portion is away from the support arm of hook body segment forming 2-5 connecting hole, and described screw is connected with the screw on spring steel through after connecting hole, and the position described spring steel offering screw forms the recess in an accommodation neck of hook portion; The support arm that described neck of hook portion is connected with hook body segment is connected with a pipe joint, on drag hook from pipe joint to the hollow pipe structure of the part of hook body segment bottom for being connected.
Preferably: two described pipe joints are connected with suction catheter, and the suction catheter other end is connected with negative pressure source.
Preferably: described hook body segment is the arc shape of arc diameter 15cm.
Compared with prior art, the beneficial effects of the utility model are: this drag hook only needs an assistant just can operate, described connecting hole is convenient to adjust distance between two drag hooks according to practical situation, to adjust the size of surgical field of view, on described drag hook from pipe joint to the hollow pipe structure of the part of hook body segment bottom for being connected, and suction catheter is connected on pipe joint, can in time the blood and slime in operation process, the broken end of bone etc. be blotted in time only like this.
