Description

Technical Field

[0001] The utility model particularly relates to an orthopedic drill bit with optimized surgical field of view. Background Art

[0002] An orthopedic drill bit is a medical device specifically used in orthopedic surgery. It is typically a slender, rotating tool with a cutting edge on the head, used to drill holes in bones. In fracture fixation surgery, an orthopedic drill bit is needed to drill holes of appropriate size in the bone for the insertion of screws, Kirschner wires, and other fixation devices. For some bone defect repair surgeries after bone tumor resection, an orthopedic drill bit may be needed to drill holes in autologous bone or allogeneic bone to facilitate vascular ingrowth and bone fusion. Common orthopedic drill bits are divided into manual bone drills, electric bone drills, and pneumatic bone drills according to their power source.

[0003] Traditional orthopedic drills lack built-in lighting. This makes it difficult for surgeons to clearly see the exact location of the hole and its relationship to surrounding tissue structures during deep-tissue orthopedic surgeries, such as posterior tibial plateau condyle fractures. The deep surgical site, obscured by surrounding tissue and limited by natural light, creates a dim visual field. Using a conventional drill in these situations, it's difficult for the surgeon to clearly see the hole's location and its relationship to surrounding tissue structures.

[0004] Therefore, it is necessary to invent an orthopedic drill with optimized surgical field of view to solve the above problems. Utility Model Content
