Abstract

The invention discloses an external fixation bracket for minimally invasive percutaneous fixation of a carpal navicular bone, which relates to the field of medical devices and includes a connecting frame, two limb fixing frames, two fixing frame position adjustment mechanisms, an aiming sleeve and an aiming sleeve fixing The two limb fixing frames are arranged at intervals and correspond to the position adjustment mechanisms of the two fixing frames; the limb fixing frame includes a screw rod, two sliding rods, two sliding blocks and two fixed bone calipers. The two sliding rods are arranged in parallel and spaced apart. The two ends of the screw rod are respectively provided with threads in opposite directions. The fixed bone calipers are connected with the two sliding blocks in one-to-one correspondence, and one end of the screw rod is rotatably connected with the position adjusting mechanism of the fixing frame. The external fixation bracket for the minimally invasive percutaneous fixation of the carpal navicular bone of the present invention has the advantages of convenient operation, high operation efficiency, high accuracy and high safety.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an external fixation bracket for minimally invasive percutaneous fixation of the scaphoid. Background technique [0002] Percutaneous internal fixation technology effectively avoids the disadvantages of open reduction and internal fixation such as large wound, periosteal soft tissue injury, and prone to nonunion. However, in the actual application process, due to the lack of experience of the surgeon, the inability to understand the anatomical structure of the fracture site, and the 2D intraoperative fluoroscopy cannot fully reflect the anatomical characteristics of the fracture area, resulting in prolonged operation time, unstable internal fixation, and internal fixation. Risks such as entry and exit. Contents of the invention [0003] Therefore, the present invention provides a minimally invasive external fixation bracket for percutaneous fixation of the scaphoid to solve the ...
