Abstract
The invention discloses an auxiliary device for the positioning and drilling of a scaphoid fixator, comprising a drilling sleeve seat (1), drilling sleeves (2), an extension rod (3) and a handle (4), wherein the drilling sleeve seat (1) is connected with the extension rod (3); a pair of drilling sleeves (2) are arranged on the drilling sleeve seat (1) by means of uniform distribution; and anti-slide stabs (21) are arranged at the front end of the drilling sleeves (2). The auxiliary device disclosed by the invention adopts a hollow structure, convenient for positioning and observing the drilling. As the matching tool with a scaphoid fixator, the auxiliary device disclosed by the invention can meet the needs of accurate positioning and drilling for the nail path of the fixator without a measurement, and avoids injuries on surrounding ligaments and soft tissues during path drilling. The scaphoid fracture fixator is ensured to be accurately installed in place, thus contributing to the restoration, fixation, and function recovery of scaphoid fracture; and the auxiliary device is very practical medical equipment for orthopedic operations.
Description
Technical field
The invention belongs to technical field of medical instruments, further belong to orthopedic instrument technical field, be specifically related to a kind ofly for fracture of scaphoid bone of wrist fixation procedure, especially in fracture of the carpal bone fixation procedure, is nut bone holder location and drilling aid.
Background technology
Fracture is the human body frequent situation that sustains an injury, and the reduction of the fracture is fixedly the most frequently used medical means.Wrist is mankind's functional parts the most flexibly, and carpal bone is that the bone piece by polylith different structure is combined into, and is complex structure.Once come to harm, its reset fixing than the reduction of the fracture difficulty at other positions will many.The reset of prior art generally adopts fixedly fracture of the carpal bone position of the resets such as Kirschner wire, fixation steel plate, because these apparatuses are fixing, intercarpal joints position is not had to pressurization, postoperative the outer fixing of long period that need, exerts a certain influence to patient's functional rehabilitation, can recover slow.And steel plate screw is fixing need to punch on less carpal bone, complicated operation, increases operation wound, affects function of joint, and postoperatively may occur the complication such as pain and infection, totally unfavorable to carpal recovery.For this reason, the inventor 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 object 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 impact of the factors such as multi-dimensional nature that bone piece coordinates, the accurate location that causes realizing with traditional apparatus fixing hole after the reduction of the fracture is still very difficult with boring, has affected the result of use of carpal bone fusion device.Therefore, developing stationary positioned device a kind of and that holder is supporting and be very important, is the best way that overcomes prior art defect.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, easy and simple to handle, contribute to the reduction of the fracture, registration, boring coordinates nut bone holder accurately to locate and drilling aid with fusion device.
Object of the present invention realizes like this, comprises drill bushing seat, drill bushing, extension rod and handle, and described drill bushing seat connects extension rod, uniform on described drill bushing seat a pair of drill bushing is set, and drill bushing front end is provided with anti-skidding thorn.
The present invention adopts engraved structure, has both been convenient to location, is convenient to again observe boring.The present invention is as the holder kit that possesses identical fixing feet, without measuring the needs that can meet accurate location and drill through the installing hole of fusion device.Having guaranteed that carpal bone fusion device is accurately in place, be conducive to the reset of patient's fracture, fixing and functional rehabilitation, is a kind of very practical orthopaedics therapy medical apparatus and instruments.
