Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect of the tools used in the prior art for resetting the femoral head. When the force is applied, the femoral head will directly abut against the posterior edge of the acetabulum and it is difficult to cross over, resulting in difficulty in resetting. Thereby providing a pull-back hip joint reduction device

Embodiment

[0047] This embodiment provides a pull-back hip joint reduction device, such as Figure 1-2 As shown, it includes: main bracket 1, chute track 2 and drawer, among which:

[0048]The main stand 1 includes a main stand body 11 , a first handle 12 disposed at one end of the main stand body 11 , and a second handle 13 disposed at the other end of the main stand body 11 . The main bracket main body 11 is used to connect other components, and the first hand-held part 12 and the second hand-held part 13 are convenient to be held by the same doctor, or two or more doctors, to lift the main bracket 1; One of the hand-held parts is supported at a certain position, and the main support 1 is assisted to be lifted by utilizing the principle of leverage.

[0049] The chute rails 2 are arranged in pairs under the main support 1, fixedly connected with the middle part of the main support 1, and used for supporting plate 3 to slide inside.

[0050] The drawing part includes a supporting boar...

Abstract

The invention provides a rear pull type hip joint reduction device which comprises a main support with a certain length; the chute rails are arranged below the main support in pairs and are fixedly connected with the middle part of the main support; the drawing part comprises a supporting plate and a drawing structure; the supporting plate is installed in the sliding groove track in a drawable mode. The drawing structure is used for pushing and pulling the supporting plate. Compared with a cylindrical repositor in the prior art, the backward-pulling type hip joint repositor changes the force application direction, the existing cylindrical repositor can only be pushed forwards along the axial direction, so that the femoral head is propped against the rear edge of the acetabulum and is difficult to span, but the repositor firstly lifts the femoral head until the femoral head is higher than the acetabulum, and then the femoral head is pushed forwards along the axial direction. According to the technical scheme, the supporting plate is pulled out through the pulling structure, the femoral head falls into the acetabulum, compared with the prior art, operation is easier, the reduction efficiency is higher, the workload of medical staff is relieved, and pain of a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pull-back hip joint reduction device. Background technique [0002] Hip replacement is currently the most effective method for the clinical treatment of severe joint disease, femoral neck fractures in the elderly, and some intertrochanteric fractures. With the aging of the population and the increasing number of bone and joint diseases, hip replacement can reconstruct the function of diseased joints and significantly improve the working ability and quality of life of patients. Now it has been widely used as a mature treatment method at home and abroad. [0003] The hip joint includes the femoral head and the acetabulum. Total hip replacement is to replace both the femoral head and the acetabulum, and then install the replaced femoral head into the replaced acetabulum, that is, reset. In normal human anatomy, the acetabulum and femoral neck itself have a certain degree ...
