Abstract
The invention discloses a carpal three-foot fusion apparatus positioning and drilling auxiliary device, which comprises a drill bushing seat (1), drill bushings (2), an extension rod (3) and a handle (4), wherein three drill bushings (2) are uniformly arranged on the drill bushing seat (1); and a non-slip thorn (21) is arranged at the front end of each drill bushing (2). By adopting a hollowed structure, the device is convenient in positioning and drilling observation. As a fusion apparatus matched tool with the same fixed feet, the device can meet the requirements for accurate positioning and drilling of mounting holes of a fusion apparatus without measurement. Accurate installation of the carpal fusion apparatus is ensured, surrounding tissues are prevented from being injured, and restoration, fixation and function recovery of patients' fracture are benefited; and the device is a very practical medical instrument for orthopedic therapy.
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 of fixation procedure that merges for fracturing, especially fracture of the carpal bone merges in fixation procedure, carry out the reduction of the fracture for fusion device is installed, Three-corner arthrodesis concentrator for carpal bones fixing and auxiliary bore hole is located 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 to be combined into by the bone piece of polylith different structure, is complex structure.Once come to harm, it resets fixing more than the reduction of the fracture difficulty at other positions.The reset of prior art generally adopts Kirschner wire, fixation steel plate etc. to reset and fixes fracture of the carpal bone position, 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, when boring, easily injure surrounding soft tissue, the impact of the factors such as the 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 fusion stationary positioned device a kind of and that fusion device 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 one simple in structure, easy and simple to handle, contribute to the reduction of the fracture, registration, boring coordinates Three-corner arthrodesis concentrator for carpal bones location and drilling aid accurately with fusion device.
Object of the present invention realizes like this, comprises drill bushing seat, drill bushing and extension rod, and described drill bushing seat connects extension rod, uniform on described drill bushing seat three drill bushings 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 fusion device 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 ensured 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.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, but never in any form the present invention is limited, and any conversion of doing based on training centre of the present invention, all falls into protection domain of the present invention.
As shown in Fig. 1 ~ 3, the present invention includes drill bushing seat 1, drill bushing 2 and extension rod 3, described drill bushing seat 1 connects extension rod 3, uniform on described drill bushing seat 1 three drill bushings 2 is set, and drill bushing 2 front ends are provided with anti-skidding thorn 21.
Described drill bushing seat 1 rear end arranges extension rod 3, described extension rod 3 front ends axially and its main part be 10 ~ 30 ° of angles.To adjust the angle between handle 4 and drill bushing seat 1 working face.To adapt to the operation requirements in fixing and boring procedure.
Described drill bushing seat 1 is " △ " shape structure of hollow out, and each bight arranges respectively drill bushing 2, and its centre arranges observation port 11, and the observation in process easy to use contributes to accurate location.Described drill bushing seat 1 adopts tight fit structure with drill bushing 2, can take over-surplus fit structure or adopt rearward end welding manner all can realize the present invention's object.
Described drill bushing 2 longitudinally arranges leading of through-hole structure and holes 22.
Described anti-skidding thorn 21 is " V " structure, and angular aperture is 45 ~ 75 °, and optimal way is 50 ~ 60 °.
Described anti-skidding thorn 21 is the zigzag structure along drill bushing 2 front end circumference uniform distributions.
Described drill bushing 2 length are 10 ~ 30 mm, and optimal way is 12 ~ 16 mm.
Neighbor distance between described drill bushing 2 is 8 ~ 25mm, and optimal way is 10 ~ 18mm.
Described extension rod 3 is threaded connection mode and is connected with drill bushing seat 1, and extension rod 3 rear ends arrange handle 4.Extension rod 3 can also be connected by clamping or fixed form with drill bushing seat 1, does not affect the realization of the object of the invention.
