Abstract

A half-needle assisted replacer for femoral shaft fracture is characterized in that a steel plate (2) is arranged at the near end of a half-needle assisted replacer sliding plate (1), and a sliding rod (3) is arranged at the far end; a plate round hole (4) is formed in the steel plate at the near end, a lifting rod (5) penetrates through the plate round hole from a fixing sleeve (6), and an anti-sliding hole (7) is formed in the side edge of the plate round hole locked by a lock screw (8); a rod round hole (9) is formed in the head end of the lifting rod, threads (10) are formed in the tail end, and the lifting rod is fixed through a lifting nut (11); a round disk (12) is arranged at the head end of the fixing sleeve, and fixing slots (13) are formed in the round disk; the sliding rod is sleeved with a sliding fixture block (14), and a fixture anti-sliding hole (16) is formed in the side edge of the sliding fixture block and locked by a clamping screw (17); the sliding fixture block is connected with an opening frame (22), a spur gear (15), a circular gear (23) and a fine adjustment rod (18) are arranged in the opening frame, a frame round hole (19) is formed in the head end of the fine adjustment rod, and a frame anti-sliding hole (20) is formed in the side edge of the frame round hole locked by a locking screw (21); a rolling handle (24) is arranged outside an axis of the circular gear.

Description

technical field [0001] The invention is a half-needle auxiliary resetter for femoral shaft fractures used in clinical orthopedics, referred to as: half-needle auxiliary resetter, which belongs to medical equipment. It is an auxiliary device for closed reduction of intramedullary nails for human femoral shaft fractures. The application of the device is not only beneficial to reducing the surgical trauma, but also beneficial to reducing the operation time. It is a repositioning device that assists the femoral fracture traction table, and it is beneficial to the closed internal fixation of the intramedullary nail. Background technique [0002] The treatment of femoral shaft fractures is developing and changing. From the invention of the intramedullary nail by German physician Gerhard Kuntscher during World War II to the later period of World War II, the survival rate and prognosis of patients with femoral shaft fractures have been improving year by year. With intramedullary ...
