Description
Technical field
This utility model belongs to technical field of medical instruments, further belong to the orthopedic instrument technical field, be specifically related to a kind of for fracture fusion fixation procedure, especially fracture of the carpal bone merges in the fixation procedure, carry out the reduction of the fracture for fusion device is installed, carpal bone four foot fusion devices fixing and auxiliary bore hole are located and drilling aid.
Background technology
Fracture is the human body frequent situation that sustains an injury, and the reduction of the fracture fixedly is the most frequently used medical means.Wrist is flexibly functional part of human beings, and carpal bone is that the bone agllutination by the polylith different structure closes and forms, and is complex structure.In case come to harm, it resets fixing more than the reduction of the fracture difficulty at other positions.The general fixedly fracture of the carpal bone positions that reset such as Kirschner wire, fixation steel plate of adopting that reset of prior art, because these apparatuses are fixing the intercarpal joints position there is not pressurization, postoperative needs the outer fixing of long period, exerts a certain influence for patient's functional rehabilitation, namely can recover slow.And steel plate screw is fixing need to punch at less carpal bone, and complicated operation increases operation wound, affects function of joint, and the complication such as pain and infection may appear in postoperative, and is totally unfavorable to carpal recovery.For this reason, this utility model people once developed multiple carpal bone fusion device and had obtained national patent, and the application of this technology substitutes traditional fixation steel plate, had reached purpose and therapeutic effect that the good reduction of the fracture is merged.But, this fusion device needs location and boring before installation, because carpal bone bone piece is little, easily injure surrounding soft tissue during boring, the impact of the factors such as multi-dimensional nature that the bone piece cooperates, cause realizing that with traditional apparatus the accurate location of fixing hole is still very difficult with boring after the reduction of the fracture, affected the result of use of carpal bone fusion device.Therefore, developing fusion stationary positioned device a kind of and that fusion device is supporting and be very important, is the best way that overcomes the prior art defective.
The utility model content
It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, and helps the reduction of the fracture, registration, and boring cooperates accurately carpal bone four foot fusion devices location and drilling aid with fusion device.
The purpose of this utility model realizes like this, comprises drill bushing seat, drill bushing and extension rod, and described drill bushing seat connects extension rod, uniform on the described drill bushing seat two pairs of drill bushings is set, and the drill bushing front end is provided with anti-skidding thorn.
This utility model adopts engraved structure, both has been convenient to the location, is convenient to again observe boring.This utility model need not to measure the needs that can satisfy accurate location and drill through the installing hole of fusion device as the fusion device kit that possesses identical fixing feet.Having guaranteed that carpal bone fusion device accurately is in place, avoided the damage of surrounding soft tissue, be conducive to resetting, fixing and functional rehabilitation of patient's fracture, is a kind of very practical orthopaedics therapy medical apparatus and instruments.
