Abstract

The utility model discloses a retractor for surgical operation. The retractor comprises a retractor body and a retractor arm, wherein the retractor arm includes a spring arm with a hook at one end, wherein the retractor body includes at least two retractor pawls; and the other end of the retractor arm is hinged with the retractor body through a gimbal. The retractor can not only retract the incision tissue to prevent the strain injury, but also obviate manual retraction, thereby reducing the work load of the medical staff.

Description

The surgical operation drag hook

Technical field

This utility model relates to the medical instruments technical field, relates in particular to a kind of surgical operation drag hook.

Background technology

When doing surgical operation, need be with surgery tractor tractive operative incision tissue so that undergo surgery operation, at present, the employed surgery tractor of hospital is more single, be fixed with a drag hook pawl below a handle exactly, when operation incision tissue is carried out tractive, the drag hook width is limited, can't on a large scale surgical field of view be exposed, and when tractive, owing to be artificial tractive, so inequality of just may exerting oneself, cause the rigid of tissue to pull, and artificial tractive also can be tired easily, makes troubles to operation technique.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of surgical operation drag hook is provided, and this drag hook not only can tractive operative incision tissue, and avoid operation incision tissue caused and pull, but also artificial tractive, minimizing medical personnel's workload.

For solving the problems of the technologies described above, the technical solution of the utility model is: the surgical operation drag hook, comprise drag hook body and drag hook arm, described drag hook arm comprises that a spring arm and an end are provided with hook, and the other end of described drag hook arm is hinged by universal joint and described drag hook body.

As a kind of improvement, described drag hook body comprises at least two drag hook pawls.

After having adopted technique scheme, effect of the present utility model is: because the surgical operation drag hook, comprise drag hook body and drag hook arm, described drag hook arm comprises that a spring arm and an end are provided with hook, described drag hook body comprises at least two drag hook pawls, the other end of described drag hook arm is hinged by universal joint and described drag hook body, therefore when carrying out surgical operation, the drag hook pawl is caught on the operative incision tissue, pulling drag hook arm, because the drag hook arm comprises a spring arm, and the drag hook arm is hinged by universal joint and drag hook body, therefore, the drag hook arm just can extend, and rotates the drag hook arm, and the drag hook pawl does not rotate, thereby just can very easily hook be hung on the fixture, so just save the artificial tractive of medical personnel, reduced medical personnel's workload, simultaneously, spring arm has also played the effect of pulling force buffering, has also avoided operation incision tissue is caused rigid pulling when surgical field of view is exposed fully.

Again because described drag hook body comprises at least two drag hook pawls, therefore the drag hook body just has enough width pulling operative incision tissues when surgical incision is long, thereby it is more thorough that surgical field of view is exposed, and operative incision is organized stressed balanced more in the time of also.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Accompanying drawing is the structural representation of this utility model embodiment;

In the accompanying drawing: 1. drag hook body; 11. drag hook pawl; 2. drag hook arm; 21. spring arm; 22. hook; 23. universal joint.

The specific embodiment

A kind of surgical operation drag hook, as shown in drawings, comprise drag hook body 1 and drag hook arm 2, described drag hook arm 2 comprises a spring arm 21, one end of described drag hook arm 2 is provided with hook 22, the other end is hinged by universal joint 23 and described drag hook body 1, and described drag hook body 1 comprises three drag hook pawls 11.

Operation principle of the present utility model is: when carrying out surgical operation, drag hook pawl 11 is caught on the operative incision tissue, pulling drag hook arm 2, because drag hook arm 2 comprises a spring arm 21, and drag hook arm 2 is hinged by universal joint 23 and drag hook body 1, therefore, drag hook arm 2 just can extend, rotate drag hook arm 2, drag hook pawl 11 does not rotate, thereby just can very easily hook 22 be hung on the fixture, so just save the artificial tractive of medical personnel, reduced medical personnel's workload, simultaneously, spring arm 21 has also played the effect of pulling force buffering, when being exposed fully, surgical field of view also avoided operation incision tissue is caused rigid pulling, three drag hook pawls 11 just have enough width pulling operative incision tissues when surgical incision is long, thereby it is more thorough that surgical field of view is exposed, and operative incision is organized stressed balanced more in the time of also.

Claims
