Description

Technical field: [0001] The invention relates to an electric cutter for osteotomy, which is mainly used for orthopedic (bone spur) surgical treatment in human joints. Background technique: [0002] The joints of the human body are distributed in various moving parts of the human body. Joint diseases often occur in the joints of the human body, which can cause bone spurs for a long time, especially for athletes and the elderly. During the treatment process, the joint bone spurs need to be removed. current technology: [0003] 1. Using open surgery and using knives to resect joint bone spurs requires high surgical techniques and troublesome operations, which cannot meet the ideal surgical effect; [0004] 2. Using arthroscope and needle knife to perform joint bone spur resection requires high surgical technique, long operation time and troublesome operation, which cannot satisfy the ideal surgical effect; [0005] 3. Using rongeurs to remove bone spurs requires a single type...
