Abstract

The utility model discloses a movable orthopedic positioning retractor, comprising a beam, a first retractor fixing element, a second retractor fixing element, a first retractor, a second retractor, a first retractor extension element, a second retractor extension element, a plurality of positioning holes, and a positioning nail, wherein the first and second retractor fixing elements are arranged on the beam; the first retractor extension element is connected with the first retractor and the first retractor fixing element; the second retractor extension element is connected with the second retractor and the second retractor fixing element; the positioning holes are formed on the beam; the positioning nail is correspondingly arranged on the second retractor fixing element; the first retractor fixing element is fixedly arranged on one side of the beam; and the second retractor fixing element can slide on the beam. The movable orthopedic positioning retractor has a simple structure and a low cost, and is convenient to use, the problem of separation between skeletons and external tissues in an orthopedic operation is effectively solved, and the participation of human resources is reduced.

Description

A kind of orthopaedics activity orientation drag hook

Technical field

This utility model relates to a kind of medical apparatus, especially a kind of orthopaedics activity orientation drag hook.

Background technology

Usually, when carrying out bone surgery, to carry out separating of skeleton and outside organization.Traditional mode adopts the drag hook of hook-type to expand separation, and this just needs the outside constant pulling force that keeps.In the manual operation process, often be difficult to guarantee this point.

Adopt external pull, not only need more manpower to participate in, simultaneously, as long as external pull changes, it causes the separated space of skeleton and tissue also can change thereupon, has increased certain degree of difficulty for the medical personnel that implement operation, has also increased the time of finishing operation.

Therefore, need a kind of new orthopaedics to use the activity orientation drag hook with the isolating problem of skeleton and outside organization in the better solution bone surgery.

Summary of the invention

In view of this, this utility model is devoted to better to solve the isolating problem of skeleton and outside organization in the bone surgery, has proposed a kind of orthopaedics activity orientation drag hook.

The technical solution adopted in the utility model is:

A kind of orthopaedics comprises crossbeam, is arranged on the first drag hook fixture and the second drag hook fixture, first drag hook on the crossbeam and is connected first drag hook with the activity orientation drag hook and the first drag hook extension, second drag hook of the first drag hook fixture and be connected second drag hook and the second drag hook extension of the second drag hook fixture and be arranged on a plurality of locating holes on the crossbeam and correspondence position is provided with on the second drag hook fixture locating pin;

Wherein, the described first drag hook fixture is fixedly installed on an end of crossbeam, and the described second drag hook fixture can be in the enterprising line slip of crossbeam.

Above-mentioned first drag hook and second drag hook are the arc drag hook.

The arc opening of above-mentioned first drag hook and second drag hook is outside opening.

The spacing distance of above-mentioned locating hole is that 1cm is to 2cm.

Above-mentioned first drag hook and second drag hook are the elastic force drag hook.

The beneficial effects of the utility model are:

This utility model is simple in structure, and cost is lower, but efficiently solves the isolating problem of skeleton and outside organization in the bone surgery, and is easy to use simultaneously, reduces outside manpower and participates in.

Description of drawings

Below with reference to accompanying drawings specific embodiments of the present utility model is described in detail, wherein:

Fig. 1 is a structure drawing of device of the present utility model;

Wherein, 1-crossbeam, the 2-first drag hook fixture, the 3-second drag hook fixture, 4-locating hole, 5-locating pin, the 6-first drag hook extension, 7-first drag hook, the 8-second drag hook extension, 9-second drag hook.

The specific embodiment

In order to solve the isolating problem of skeleton and outside organization in the bone surgery, this utility model provides a kind of orthopaedics activity orientation drag hook.Next specify this orthopaedics activity orientation drag hook.

Fig. 1 illustrates structure drawing of device of the present utility model.

This orthopaedics comprises crossbeam 1, is arranged on the first drag hook fixture 2 and the second drag hook fixture 3, first drag hook 7 on the crossbeam 1 and is connected first drag hook 7 with the activity orientation drag hook and the first drag hook extension 6, second drag hook 9 of the first drag hook fixture 2 and be connected second drag hook 9 and the second drag hook extension 8 of the second drag hook fixture 3 and be arranged on a plurality of locating holes 4 on the crossbeam 1 and correspondence position is provided with on the second drag hook fixture 3 locating pin 5.

Wherein, the described first drag hook fixture 2 is fixedly installed on an end of crossbeam 1, and the described second drag hook fixture 2 can be in crossbeam 1 enterprising line slip.

Above-mentioned first drag hook 7 and second drag hook 9 are the arc drag hook.

The arc opening of above-mentioned first drag hook 7 and second drag hook 9 is outside opening.Outwards opening meets mechanics principle, can better separate sclerotin and outside organization.

The spacing distance of above-mentioned locating hole 4 is that 1cm is to 2cm.The 1cm that experiment showed, by limited number of time is its optimum.

Above-mentioned first drag hook 7 and second drag hook 9 are the elastic force drag hook.The elastic force drag hook is contacting between drag hook and the outside organization fully, guarantees the stressed all even excessive tearing outside organization that avoids.The elastic force drag hook can be has certain elastic plastics drag hook, simultaneously has certain rigidity again, and the other forms of drag hook that satisfies aforementioned requirement is also in the scope of this utility model protection.

More than specific descriptions of the present utility model are intended to illustrate the implementation of specific embodiments can not be interpreted as it is to restriction of the present utility model.Those of ordinary skills can make various variants on the basis of the embodiment that describes in detail under instruction of the present utility model, these variants all should be included within the design of the present utility model.This utility model scope required for protection is only limited by described claims.
