[0002] The arc-shaped compression forceps is a medical device specially designed for orthopedic surgery, which is mainly used to apply pressure and fix the fracture site to promote the healing of the fracture.

[0003] During fracture treatment, anesthesia is used to ensure painlessness, the skin and muscles are cut to expose the fracture site, and the injured part is temporarily reduced and fixed using fracture compression forceps. Then, internal fixation implants such as bone plates are used for fixation, and cortical bone screws are implanted to achieve the compression reduction effect.

[0004] However, when reducing the trauma site, the fracture arc pressure forceps usually cannot fix the bone plate at the same time.
