Description

Technical Field

[0001] The present application belongs to the field of periacetabular osteotomy surgery, and in particular, relates to a detachable osteotome for navigation or robotic periacetabular osteotomy. Background Art

[0002] Periacetabular osteotomy is a surgical method for treating hip diseases, especially for diseases such as hip dysplasia and hip osteoarthritis. Traditional surgical methods rely on the doctor's experience and feel, which greatly limits the accuracy and repeatability of the surgery. Because the periacetabular osteotomy is located deep in the area and is surrounded by nerves and blood vessels, surgical exposure is difficult and the exposure range is limited. In addition, due to the diversity of hip lesions, this surgery is one of the most complex orthopedic surgeries and is the crown jewel of orthopedic surgery.

[0003] In traditional periacetabular osteotomy, the bone knife is integrated. If you want to replace the square bone knife, curved bone knife and double-shoulder bone knife, you need to replace the whole bone knife. Moreover, the positioning of the bone knife can only be targeted at a specific surface.

[0004] Therefore, how to achieve precise positioning during periacetabular osteotomy surgery and improve the accuracy and safety of the surgery without having to replace the bone cutter as a whole is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention
