Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic splint instruments, in particular to an orthopedic splint installation and fastening device. Background Art

[0002] Orthopedic splints are usually plate-like pieces made of wood, bamboo, cardboard or plastic. The splints are fixed to the limbs where the fractures have been reduced by bandages to facilitate the healing of the fracture ends under relatively static conditions. At the same time, they are combined with gradual functional exercises to promote fracture healing and restore limb function. Since the current splints rely on bandages for binding and tightening, their stability is poor. Especially for splints on fingers, Velcro is also used for tightening. Not only will the splints have loose clearance after tightening, but also due to the easy disassembly feature, the bandages or Velcro will loosen, resulting in the problem of splint clamping failure. Therefore, those skilled in the art hereby propose a solution for an orthopedic splint installation and fastening device. Utility Model Content
