Abstract

A posterolateral approach bone lever for hip replacement comprises a handle (1). One side of the front end of the handle (1) is provided with a lower arm (2), the other side of the front end of the handle (1) is provided with a rear arm (3), and an arc opening (4) with radian matched with the lower rear radian of an acetabulum is formed between the lower arm (2) and the rear arm (3). By the aid of the posterolateral approach bone lever, the acetabulum and lower and rear portions of the acetabulum can be exposed sufficiently, the defect of difficulty in sufficiently exposing the acetabulum and the lower and rear portions of the acetabulum through a past retractor is overcome, and simultaneously the problem of operation with a plurality of retractors is solved. In addition, when clinically applying the posterolateral approach bone lever, a doctor can operate the bone lever with only one hand, the other hand of the doctor is freed, the bone lever is operated conveniently, an incision can be narrowed relatively, the hip replacement belongs to minimal incision surgeries, the amount of bleeding is small, the pain of a patient is relieved, and a postoperative scar is also narrowed.

Description

The posterolateral approach bone sled that is used for hip replacement

Technical field

This utility model relates to medical instruments field, specifically, relates to a kind of posterolateral approach bone sled that is used for hip replacement.

Background technology

Replacement of Hip Joint has been widely used in clinical, treatment hip joint injury at present, removes pain, rebuilds function of joint.This operation is also more and more universal.How to carry out in the Replacement of Hip Joint and operate, the exposure in the art is very important, especially the exposure of acetabular bone.In posterolateral approach, after neck of femur cuts bone, pull near end of thighbone preceding and expose the mortar front side with bone sled, down, rear side exposes and need two drag hooks usually, often can not well the outward turning muscle group be retracted, it is insufficient to expose acetabular bone, has prolonged operating time.

Summary of the invention

The purpose of this utility model provide a kind of easy to operate, and can dwindle the posterolateral approach bone sled that is used for hip replacement of otch relatively.

The technical scheme that realizes above-mentioned purpose is: a kind of posterolateral approach bone sled that is used for hip replacement; Comprise handle; Front end one side of handle has following side arm, and opposite side has posterolateral arm, and forms down the arc opening that the following back radian with acetabular bone is complementary between side arm and the posterolateral arm.

After adopting technique scheme; Wherein arm sled is below acetabular bone (closed pore); Arc opening with the handle front end props up rear arc place under the acetabular bone again, and bone sled remainder can retract the outward turning muscle group, can fully expose acetabular bone and below thereof and rear part; Solve the difficult defective that fully exposes acetabular bone and below and rear part of drag hook in the past, solved the problem of Duola's hook operation simultaneously.In addition, this invents Clinical application, and the doctor is as long as with a hand operated bone sled, liberated the another hands; Easy to operate, otch also can relatively dwindle, and belongs to small incision surgery; Amount of bleeding is few, has alleviated patient's misery, and the cicatrix of postoperative has also dwindled.

Fig. 3 is the perspective view of this utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment this utility model is done further detailed explanation.

Shown in Fig. 1 ~ 3; A kind of posterolateral approach bone sled that is used for hip replacement comprises handle 1, and front end one side of handle 1 has following side arm 2; Opposite side has posterolateral arm 3, and forms down the arc opening 4 that the following radian afterwards with acetabular bone is complementary between side arm 2 and the posterolateral arm 3.

The operation principle of this utility model is following: will wherein descend side arm 2 sleds below acetabular bone (closed pore); Arc opening 4 with handle 1 front end props up rear arc place under the acetabular bone again; Bone sled remainder can retract the outward turning muscle group; Can fully expose acetabular bone and below thereof and rear part, solve the difficult defective that fully exposes acetabular bone and below and rear part of drag hook in the past, solve the problem of Duola's hook operation simultaneously.In addition, this invents Clinical application, and the doctor needs only the handle 1 with a hand operated bone sled, has liberated the another hands; Easy to operate, otch also can relatively dwindle, and belongs to small incision surgery; Amount of bleeding is few, has alleviated patient's misery, and the cicatrix of postoperative has also dwindled.

Claims

1. a posterolateral approach bone that is used for hip replacement is prized; Comprise handle (1); It is characterized in that: front end one side of handle (1) has following side arm (2); Opposite side has posterolateral arm (3), and forms down the arc opening (4) that the following radian afterwards with acetabular bone is complementary between side arm (2) and the posterolateral arm (3).
