Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fracture treatment device. Background Technology

[0002] The origins of fracture treatment devices can be traced back to ancient medicine. Early doctors used simple tools such as bandages and splints to fix fracture sites, reduce movement, and promote healing. Over time, especially after entering the 19th century, advances in surgical medicine spurred the development of more complex fracture treatment techniques and equipment. Modern fracture treatment devices are mainly divided into two categories: external fixators and internal fixators. External fixators maintain bone stability by fixing a metal frame to the outside of the bone and are often used for patients with severe fractures or multiple fractures. This device can help align bones without invading the body, effectively reducing the risk of infection.

[0003] However, existing fracture treatment devices have the following drawbacks:

[0004] (1) At present, the device does not have a good overall fixation effect when fixing the patient's bones, which can easily affect subsequent normal operations.

[0005] (2) Currently, when facing different patients' bones, the device has limited functionality and it is difficult to change the distance between the fixation blocks, thus reducing the overall effectiveness. Utility Model Content

[0015] (III) Beneficial Effects
