In the treatment of human joints, it is found that joint diseases often occur in joint joints, and bone spurs may occur for a long time, especially for athletes and the elderly. During the treatment process, the bone spurs at joint joints need to be removed. Open surgery for joint bone spur removal requires high surgical technique, troublesome operation, and slow recovery of the patient's wound. Arthroscopy and acupuncture are also used to remove joint bone spurs. Similarly, the surgical technique requires a long time and cannot achieve satisfactory surgical results. , so the rongeur is a surgical instrument used for biting off necrotic rotten bones and correcting bones in orthopedic surgery.

After investigation, it was found that there are various problems in the rongeurs on the market. First, the forceps head cannot be replaced, and it needs to be in constant contact with the hard bone fragments during the operation, which will inevitably cause wear and tear, resulting in the failure to clamp the broken bones. Second, , Replaceable spring support piece, after a long time of use, the spring piece loses its elasticity and cannot achieve the purpose of automatically clamping the broken bones. Third, there is no anti-skid treatment, which will make the fingers loose after long-term use, causing them to slip off. Fourth, the connection between the rotating arm and the transmission is complicated, the production process is cumbersome, and the moving parts of the transmission rod are not strong enough and fall off easily.
