Description
Technical field
The present invention relates to reduction of the fracture technical field of tools, is specifically related to a kind of pressurizing and propping device.
Background technology
After fracture, the both ends of fracture can misplace under the traction of Surrounding muscles, it is necessary to be added in fracture operation
Press operation and operation is strutted, adjust the position of fracture and reset the both ends of fracture and dock, be then fixed.Typically now use
The reset that following two methods are fractured：
（1）Hand-reset.The method makes fracture, it is necessary to the position of the adjustment fracture of Medex or nurse in operation manually
Both ends docking reset.For the less position of the bones such as finger, toe, crawl is difficult, operation inconvenience；For arm, leg
Deng more sturdy position, because fracture Surrounding muscles strength is larger, such a method causes doctor or nurse is very easy to fatigue,
Multiple doctor's cooperatings are needed if necessary so that operating space is more crowded, easily mutually blocks, collides with.
（2）Instrument auxiliary pressurized struts.The method, first by the angle adjustment of fracture it is good after, then at both ends of fracture point
Other fixation Kel's needle, during this, the Kirschner wire at both ends of fracturing must be parallel to facilitate the fixed cover of insertion pressurizing and propping instrument
In, finally pressurizing and propping instrument is fixed on Kirschner wire again, the both ends of fracture are exerted a force by Kirschner wire, carry out pressurized operation
Operated with strutting.Existing pressurizing and propping instrument is to be connected by fixed cover with Kirschner wire mostly, it is desirable to the angle at both ends of fracturing
After adjusting, the Kirschner wire at both ends of fracturing, which parallel can just must be penetrated in fixed cover, to be operated.In actual use, although
It is first that the angle adjustment of fracture is good, but when installing Kirschner wire in fracture, fracture can move unavoidably, cause both ends angle weight of fracturing
After newly adjusting, the Kirschner wire at both ends of fracturing can't be accurately parallel, and this can cause to enter using existing pressurizing and propping instrument
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.
The content of the invention
