The invention provides a position indicator and a positioning processing method. The position indicator comprises a fixed part, a mobile part, a link mechanism, a detection part and a processing part.The fixed part is used for being arranged at the predetermined position; the mobile part is movably arranged; one end of the link mechanism is movably connected with the fixed part, and the other endof the link mechanism is movably connected with the mobile part; the detection part can detect the relative positions of the fixed part and the link mechanism and the relative positions of the mobilepart and the link mechanism; the processing part is electrically connected with the detection part and used for receiving detection information of the detection part, calculating position informationof the mobile part relative to the fixed part and judging whether or not the mobile part reaches the target position. According to the technical scheme, the position of the acetabulum can be accurately positioned, the position indicator is applied to auxiliary operation in the hip joint surgery, the situation is avoided that a doctor operates the position indicator by depending on experience, theposition indicator can adapt to the difference of different patients, the surgery efficiency and quality are improved, overhauling is avoided, the pain and economic burden of the patients are reduced, and the cost of medical institutions is reduced.
Description
Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a positioning instrument and a positioning processing method. Background technique [0002] Hip joint implants are important artificial implants that replace damaged human hip joints by using metal or non-metal substitutes with good biocompatibility and mechanical properties in surgical implants. With the gradual improvement of living standards, people have higher and higher expectations for medical effects. In recent years, the amount of hip replacement surgery has gradually increased. [0003] With the gradual increase in the amount of surgery, many complex hip replacements, hip joint resections caused by bone tumors, and complex acetabular revision surgeries have gradually increased. How to accurately locate the position and direction of the acetabulum in hip surgery is an important factor affecting the success or failure of the operation, the postoperative effect an...
