Abstract
The utility model discloses a patella screw tap. A tap body is composed of a tap tip, a tap neck and a tap handle, wherein the tap tip, the tap neck and the tap handle are disposed at a front end, a middle part and a rear end of the tap body respectively; and round holes are disposed in the center of the tap tip. The patella screw tap is simple and convenient to operate; and by using the patella screw tap, surgical sutures are pretty and surgical cost is low, thus making the tap suitable for popularization and application in orthopaedic surgical operations.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of patella screw tap.
Background technology
When usually doing the Patella fracture operation, adopt traditional " AO " fixation (tension band wiring fixation with steel wire method) to perform the operation, such operation, operation is complicated, and the operation wound face is large, is unsuitable for the early stage function of joint exercise of postoperative, and postoperative stays sequela easily.After deliberation, the inventor has created a kind of operating theater instruments, can be without planter cast, and the patient has reduced misery.
Summary of the invention
Not enough for overcoming above-mentioned prior art, the utility model discloses a kind of patella screw tap, opening operation is young, and operating time is short, and wound is little, and postoperative can carry out function exercise in early days.
The technical scheme that this utility model adopts is a kind of patella screw tap, and consisting of, the front end of cone is the cone point to cone by cone point, cone neck, cone, and middle is the cone neck, and the rear end is bored sharp center circular hole is set for the cone handle.
The cone point of described patella screw tap is platypelloid type, bores sharp center two circular holes one in front and one in back are set.
The cone neck diameter of described patella screw tap is 4mm.
The cone of described patella screw tap is 1/3rd of cone point, cone neck length degree sum to length.
The cone of described patella screw tap is being wooden or steel.
Circular hole of the present utility model can also can both reach the effect of wearing steel wire for other modification shape, finishes fracture binding operation.
Operation process is: cut skin, be close to the patella upper limb with this utility model and pass the quadriceps femoris tendon, this utility model circular hole penetrates 2 steel wires and retracts, then, be close to the patella lower edge and above-mentioned penetrate equidirectional passes with this utility model, wherein one homonymy one end of aforementioned 2 steel wires is penetrated the utility model circular hole, one end of the not homonymy of another root is walked around quadriceps femoris top and is penetrated another circular hole of utility model, retract with this utility model, 2 steel wires are fastened respectively separately, form ring and prick and " 8 " tension force banding pattern.This mode of operation, easy, wound face is little, does not need planter cast after the operation, exercise can reach 7 days and go down on one's knees 90 degree according to systemic-function, and patient's walking in 14 days is left hospital, and the sufferer misery obviously alleviates, and operating time shortens greatly.
The beneficial effects of the utility model are to have shortened operating time, have reduced the operation wound face, and it is painful to have alleviated sufferer, and without planter cast, functional rehabilitation is good and fast.This utility model is easy and simple to handle, operation stitching is attractive in appearance, the operation is with low cost, and suitable bone surgery is applied.
