[0005] How to accurately insert the acetabular cup into the acetabular bone tissue of the human pelvis is an important topic for medical personnel. Generally speaking, the medical personnel will hold a rod-shaped acetabular cup implanter. The acetabular cup is set in a thread-locking manner. During the operation, the medical personnel insert the acetabular cup implanter into the patient's pelvic acetabular bone tissue for installation, and the acetabular cup reaches the installation position in the body. and rotate the acetabular cup implanter to unload the acetabular cup, however, the existing acetabular cup implanter is not only complex in structure, but also not ergonomic and difficult to operate when installing the acetabular cup, resulting in In order to solve the troubles of medical staff, there is a need for improvement

The invention discloses an acetabular cup implanter, comprising an acetabular cup, a shell and a transmission mechanism, wherein the transmission mechanism comprises at least one transmission rod and an operating rod; the operating rod performs angular displacement around a pivot and comprises a forwarding position and a draw-back position; when the operating rod is located at the forwarding position, the transmission rod moves forward, a user can rotate the operating rod to enable the acetabular cup to rotate; when the operating rod is located at the draw-back position, the transmission rod moves backward to allow the acetabular cup to lean against one end of an extension part to fix the acetabular cup. With the adoption of the above-mentioned structure, the implanter can facilitate operating personnel to mount the acetabular cup to a proper location in the human pelvis acetabular bone tissue; and the operating rod can be rotated and operated to unload the acetabular cup to a mounting location. The acetabular cup implanter is simple in structure and easy to operate, and accords with ergonomics.
Description
technical field [0001] The invention relates to an acetabular cup implanter, in particular to an acetabular cup implanter which is simple in structure and conforms to ergonomics and is easy to operate. Background technique [0002] The hip joint is the junction of the acetabulum and the femoral head, and the hip joint, cartilage, synovial membrane, and fibrous capsule help to form a flexible spherical joint. Its structure is like a ball embedded in a groove, so The structure makes the hip joint have high stability to support the weight of the human body. [0003] People need to use the hip joint as a support point to support various activities of the human body. Therefore, if the hip joint is functionally impaired due to factors such as high degree of degeneration, rheumatoid disease, trauma or disease, such as: degenerative hip arthritis, rheumatoid hip Hip diseases such as arthritis, traumatic hip arthritis, and congenital hip dysplasia are bound to greatly affect people'...
