Description
Technical field
The invention belongs to technical field of medical instruments, further belong to the orthopedic instrument technical field, be specifically related in a kind of the fracture of scaphoid bone of wrist fixation procedure that is used for, especially the fracture of the carpal bone fixation procedure, be nut bone holder location and boring auxiliary device.
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 mankind's functional parts the most flexibly, and carpal bone is that the bone bonded by the polylith different structure forms, and is complex structure.In case come to harm, it resets fixing desirable 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 external fixation of long period, exerts a certain influence for patient's functional rehabilitation, promptly can recover slow.And steel plate screw is fixing need on less carpal bone, punch, and complicated operation increases operation wound, influences function of joint, and complication such as pain and infection possibly appear in postoperative, and is totally unfavorable to carpal recovery.For this reason, the inventor once developed multiple carpal bone fusion device and had obtained national patent, and this The Application of 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, and the influence of the factors such as multi-dimensional nature that the bone piece cooperates; Cause the accurate location and the very difficulty of holing still, influenced the result of use of carpal bone fusion device with fixing hole after traditional apparatus realization reduction of the fracture.Therefore, developing a kind of and the supporting stationary positioned device of holder and be very important, is the best way that overcomes the prior art defective.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, easy and simple to handle, help the reduction of the fracture, the location accurately, boring cooperates the nut bone holder location and the auxiliary device of holing accurately with fusion device.
The object of the invention is realized like this, comprises drill bushing seat, drill bushing, extension rod and handle, and described drill bushing seat connects extension rod, is uniformly distributed with on the described drill bushing seat a pair of drill bushing is set, and the drill bushing front end is provided with anti-skidding thorn.
The present invention adopts engraved structure, both has been convenient to the location, is convenient to observe boring again.The present invention need not to measure the needs that can satisfy accurate location and drill through the installing hole of fusion device as the holder kit that possesses the same fixed foot.Having guaranteed that the carpal bone fusion device accurately is in place, helped resetting, fixing and functional rehabilitation of patient's fracture, is a kind of very practical orthopaedics therapy medical apparatus and instruments.
