Abstract

The invention relates to an iliac nail, which comprises a nail body extending in the axial direction; the two ends, in the axial direction, of the nail body are the front end and the rear end respectively, the front end of the nail body is a threaded section with external threads, and the rear end of the nail body is provided with a nail cap integrally formed with the nail body; a connecting section between the threaded section and the nail cap is a polished rod section with a smooth outer wall, the end part of the front end of the nail body is of a blunt structure without a cutting edge, an external thread on the threaded section is spirally arranged along the outer peripheral wall of the front end of the nail body towards the rear end, and the starting position of the external thread is positioned on the blunt structure of the front end of the nail body. According to the invention, the percutaneous hollow screw solves the problem that an existing percutaneous hollow screw is prone to causing vascular nerve injury in an operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an iliac nail. Background technique [0002] Pelvic fractures caused by high-energy injury mechanisms (traffic injuries, falls from heights, etc.) are often accompanied by multiple organ dysfunction, with high mortality and disability rates. The routine treatment process for pelvic fractures includes: ① First aid resuscitation to save lives; ② Control of bleeding; ③ Treatment of associated injuries; ④ Fracture reduction, temporary stabilization and final reduction. However, when the patient's vital signs are stable and surgical treatment of pelvic fracture is required, the conventional treatment is open reduction and internal fixation, which often requires different degrees of excessive surgical exposure in order to obtain the ideal internal fixation effect. This will inevitably bring huge iatrogenic injuries to patients, including intraoperative well-known nerve and blood vessel ...
