Abstract

The invention discloses a hip-protecting percutaneous minimally invasive precise positioning bone taking, pressure reducing and bone grafting device, relates to the technical field of medical instruments. The device can precisely regulate and control the angle of each patient according to the anteversion angle and collodiaphyseal angle parameter of each patient, realize precise positioning of a femoral head necrosis area and precisely assist in marrow core drilling to fully reduce the pressure of the necrosis area. Under percutaneous, closed and minimally invasive surgeries, drilling hole channel bones can be reused, the graft can be completely delivered, the operation time is shortened, and the operation wound is reduced. The hip-protecting percutaneous minimally invasive precise positioning bone taking, pressure reducing and bone grafting device comprises a positioning guide component and a bone taking and grafting component. A positioning needle penetrates through the positioning guide component and is inserted into the bone substance. The positioning guide component is used for adjusting the angle and position of the positioning needle. The bone taking and grafting component can be arranged on the positioning needle in a sleeving mode. The bone taking and grafting component is used for taking out a femoral head necrosis focus and healthy sclerotin in the head and neck and implanting a filling material.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hip-preserving percutaneous minimally invasive and precise positioning bone harvesting device for decompression and bone grafting. Background technique [0002] Necrosis of the femoral head is a common and refractory disease in clinical practice. If it is not treated properly, it can lead to collapse of the femoral head and damage to the function of the hip joint. Therefore, it is of great significance to perform hip-preserving treatment before the collapse of the femoral head (early necrosis of the femoral head). At present, the method of decompression by drilling the medullary core of the femoral head is the main method, which can not only reduce the high pressure in the femoral head through drilling, but also improve the venous return. . At the same time, artificial bone, allogeneic bone, autologous bone, mesenchymal stem cells, and biomaterials can be implanted in ...
