Description

Pressurizing and propping device

Technical field

The utility model relates to reduction of the fracture technical field of tools, are specifically related to a kind of pressurizing and propping device.

Background technique

After fracture, the both ends of fracture can misplace under the traction of Surrounding muscles, in fracture operation, be added Press operation and operation is strutted, the position for adjusting fracture resets the both ends of fracture to dock, be then fixed.Typically now use The reset that following two method is fractured:

(1) hand-reset.The method needs Medex or nurse manually to adjust the position of fracture during surgery, makes The both ends of fracture, which are docked, to be resetted.Position lesser for bones such as finger, toes, crawl is difficult, inconvenient；For arm, The more sturdy position such as leg, since fracture Surrounding muscles strength is larger, such method is very easy to doctor or nurse Fatigue needs multiple doctor's cooperatings when necessary, so that operating space is more crowded, is easy mutually block, collide with.

(2) tool auxiliary pressurized struts.The method, after first adjusting the angle of fracture, then at the both ends of fracture point Other fixation Kel's needle, during this, the Kirschner wire at both ends of fracturing must facilitate the fixing sleeve of insertion pressurizing and propping tool in parallel In, finally pressurizing and propping tool is fixed on Kirschner wire again, is exerted a force by both ends of the Kirschner wire to fracture, carries out pressurized operation It is operated with strutting.Existing pressurizing and propping tool is to be connect by fixing sleeve with Kirschner wire mostly, it is desirable that the angle at both ends of fracturing After adjusting, the Kirschner wire at both ends of fracturing can must be penetrated just in fixing sleeve in parallel to be operated.In actual use, although First the angle of fracture is adjusted, but when installing Kirschner wire in fracture, fracture can inevitably be moved, and lead to both ends angle weight of fracturing After newly adjusting, the Kirschner wire at both ends of fracturing can't be accurately parallel, this will lead to using existing pressurizing and propping tool into Row pressurized operation and after strutting operation, the docking at both ends of fracturing has slight dislocation, and docking is resulted even in when serious and is failed.
