Abstract

The invention discloses a minimally invasive surgery guider for wrist navicular fractures. A horizontal adjusting plate is arranged at the upper end of a support. Two ends of the rear side of the horizontal adjusting plate are fixedly connected with the upper end of the support through fastening bolts. Two front ends of the horizontal adjusting plate are connected with the upper end of the supportmovably through vertical adjusting bolts. Two adjusting grooves are formed in the front side and the rear side of the horizontal adjusting plate symmetrically. Horizontal angle adjusting bolts are arranged in the adjusting grooves, and sleeve fixed angle rods. A support rod is arranged on one side of each fixed angle rod. A slider is arranged in the middle of each support rod. The minimally invasive surgery guider has the advantages of simple structure, reasonable design, positioning accuracy, good position of implants, avoidance of repeated fluoroscopy, effectively-reduced surgery time, andimproved working efficiency.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive surgical guide for scaphoid fractures. Background technique [0002] The scaphoid is the most radial part of the proximal row of carpal bones. Due to its unique anatomical shape and biomechanical characteristics, it has the highest incidence of fracture among all carpal bones. The irregular shape of the scaphoid also makes the fracture line easy to be blocked in ordinary X-ray films, resulting in missed diagnosis. In addition, its unique blood supply system makes the necrosis rate of the proximal fragments and fracture unevenness after proximal fractures. The healing rate is high, so until now the research and discussion around the scaphoid fracture is still a hot spot in the field of hand surgery. [0003] At present, when performing minimally invasive surgery for scaphoid fractures, repeated X-ray fluoroscopy is generally required, the radiation do...
