Problems solved by technology

[0005]Therefore, the technical problem to be solved by the present invention is to overcome the tools used to reset the femoral head in the prior art. When the force is applied, the femoral head will directly touch the It is difficult to cross the posterior edge of the acetabulum, resulting in difficult technical defects in reduction, so as to provide a lifting hip reduction device

Embodiment

[0058] This embodiment provides a lifting type hip joint reduction device, such as Figure 1-3 As shown, it includes: a main bracket 1, a supporting plate 2 and a lifting member 3. in:

[0059] The main stand 1 includes a main stand body 15 , a first handle 16 disposed at one end of the main stand body 15 , and a second handle 17 disposed at the other end of the main stand body 15 . The main frame main body 15 is used to connect other parts, and the first hand-held part 16 and the second hand-held part 17 are convenient to be held by the same doctor, or two or more doctors, to lift the main frame 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.

[0060] The supporting plate 2 is arranged under the main frame 1 and connected to the middle of the main frame 1, and has a first overturning state suitable for inserting under the femoral head and a second overturning state suit...

Abstract

The invention provides a lifting type hip joint reduction device which comprises a main support with a certain length; the supporting plate is arranged below the main support, is connected with the middle part of the main support, is suitable for being inserted below the femoral head, and has two different overturning states; and the lifting part is used for lifting the supporting plate to be switched between the two overturning states. Compared with a cylindrical repositor in the prior art, the lifting type hip joint repositor changes the force application direction, an existing cylindrical repositor can only be pushed forwards in the axial direction, consequently, the femoral head abuts against the rear edge of the acetabulum and is difficult to span, the femoral head is lifted to be higher than the acetabulum, then the lifting structure is lifted, and the hip joint repositor can be used for repositing the hip joint. According to the technical scheme, the turning state of the supporting plate is converted, the contact region between the femoral head and the supporting plate is gradually reduced along with conversion of the state of the supporting plate till the femoral head falls into the acetabulum, and compared with the technical scheme, the operation is easier, the reduction efficiency is higher, and the workload of medical staff is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lifting type 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 degr...
