Description

A kind of calcaneus positor

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to calcaneus in a kind of trauma operation and resets and fixed apparatus.

Background technology

Fracture of calcaneus is one of classification of fracture common in wounded patient, and serious fracture of calcaneus can be because of the malunion of traumatic arthritis and calcaneus, causes intractable pain and the dysfunction of foot, has a strong impact on patient's walking and quality of life.

The method for the treatment of fracture of calcaneus can be divided into conservative and operative treatment, can select different therapeutic modalities for dissimilar fracture of calcaneus.Avulsion fracture of calcaneus and take conservative treatment more common without the corpora calcanei fracture of displacement.Operative treatment is often taked in corpora calcanei complete fracture companion displacement, common modus operandi is using steinman pin as lever, insert the reduction of the fracture in heel from sufficient rear percutaneous, the method need to be by steinman pin through calcaneus, even need through subtalar joint, the postoperative reset that needs indwelling to maintain fracture in body, and need exposure portion needle body in external simultaneously, in order to taking out steinman pin after healing.There is the better reduction of the fracture and fixed effect in this tradition fixing means reset calcaneus, is one of classical calcaneus reset mode.

But reset and fixing mode have caused the cartilage surface of subtalar joint to destroy, and increase the risk of traumatic arthritis, still need steinman pin indwelling a period of time after fixing, the pin site infection causing is thus much.

At present except steinman pin fixed form, the day by day extensive use of steel plate screw systematic treating fracture of calcaneus, but mainly fixing for after the reduction of the fracture of each series steel plate system still lacks and is directed to specially calcaneus fracture diaplasis and fixing apparatus.

Utility model content

The purpose of this utility model is to provide special calcaneus in a kind of fracture of calcaneus operation to reset and fixed apparatus.

This utility model is in order to improve the reset rate of fracture of calcaneus in art and to improve the efficiency of operation, for operative treatment fracture of calcaneus, design a kind of calcaneus positor, for patient provides multiple conventional effectively size Selection, improve calcaneus reset efficiency, so that the width of effective reset calcaneus and height, at utmost improve patient's function in Rhizoma Atractylodis Macrocephalae, effectively improve fracture of calcaneus cure rate.

The technical solution of the utility model is as follows:

In order to realize foregoing invention object, this utility model provides a kind of calcaneus positor, comprises caliper, associating axle and pincers leading section, and described caliper is made up of handgrip, clamp handle and draw-in groove; Described pincers leading section is " scallop " type on coronalplane, is binding clip foremost; Described binding clip has undaform tooth.

Described binding clip has undaform tooth, and its contact area is larger.

Described clamp handle is annular.

Described draw-in groove, preferably, is made up of arc-shaped slot plate and draw-in groove, the overlapped interlocking of the flank of tooth in the flank of tooth and draw-in groove on arc-shaped slot plate.

A kind of calcaneus positor that this utility model provides, can be designed to one group of calcaneus positor that possesses multiple diameter and width, comprises small-sized, medium-sized, large-scale; It is advantageous that can be with its various shape the calcaneus anatomic differences to adapt to cause due to individual variations such as patient age, sex, builds in clinical operation, practical and efficient.

This utility model provides a kind of calcaneus positor, preferably, has 3 kinds of sizes:

Small-sized calcaneus positor length is 4cm, and width is 3cm;

Medium-sized calcaneus positor length is 6cm, and width is 4cm;

Large-scale calcaneus positor length is 8cm, and width is 5cm.

Above-mentioned length, refers to the major axis longest diameter of calcaneus positor binding clip;

Above-mentioned width, refers to the minor axis longest diameter of calcaneus positor binding clip.

Because serial calcaneus positor of the present utility model has sizes, allow patient have more choice, more can save the most of reseting fracture of patient and temporary fixed time.

In art, use: the calcaneus positor of selecting to be applicable to patient's build, in the situation that cutting exposure or closed reduction, use calcaneus positor to clamp calcaneus rear sclerite, to back lower place traction sclerite, reach the object of the reduction of the fracture, use the mode such as Kirschner wire or screw simultaneously, the sclerite having resetted is fixed, under fluoroscopy during operation, measure calcaneus Bei Shi angle, after seeing that the reduction of the fracture is fixing, unclamp calcaneus positor.

Calcaneus positor tool of the present utility model has the following advantages:

(1) calcaneus positor of the present utility model has good dissection radian, in completing the reduction of the fracture, realizes the temporary fixed calcaneus having resetted in art.

(2) model is various, has sizes, can greatly reduce fracture of calcaneus operative reduction complexity, improves operation efficiency.

(3) on the basis of this series, can derive more Multiple Shape, size, the calcaneus positor of thickness and other kind reduction of the fracture apparatuses, promoted conformability.
