Abstract
The utility model relates to a pressured screw three-wing nail, which belongs to fixing devices of fixing thighbone fracture. The utility model is mainly composed of a three-wing casing nail 3 and a screw nail body 4, wherein, the three-wing nail 3 is connected to the rear end of the screw nail body 4, and is fixed by a nut and a stainless steel gasket. The utility model overcomes the problems of easy rotation and slide existing in the prior art when three-wing nails and screw nails fix thighbone fractures, and reduces the pain of patients caused by fixation devices after fracture fixation.
Description
The utility model relates to a kind of holder for the treatment of Fracture of femur.
At present, the staple that is used for the treatment of Fracture of femur mainly contains two kinds, the one, the pressurization spiral nail, its mode is by the drill bit screw thread that is located at the spiral nail front end that the slight crack butt joint of Fracture of femur is fixed, the 2nd, three wing nail, because though the pressurization spiral nail makes the slight crack of fracture tightly involutory, the anglec of rotation was bigger when but femur was movable, though there is the spiral nail resected femur still can be along hand of spiral activity, therefore contour structures is shaped as the femur rotation problem that prismatoidal three wing nail has replaced spiral nail, but has but exposed the problem that makes the femur opposite joint slippage sternly not occur.
The purpose of this utility model is exactly a kind of new fixer when fixing and treat Fracture of femur in conjunction with the advantage design of three wing nail and spiral nail.
Formation of the present utility model is with three wing nail and spiral nail strikes up partnership and one is used to extract three wing nail extractor.At spiral nail folding nail body head end still is the drill bit screw thread, end is four prismatic spiral shell buttons, terminal nail body lacks cylindric for circle, three wing nail is a tubular cylinder shape, its internal diameter is to lack cylindrical with the terminal belled circle of spiral nail body, have one to protrude sword at its tail end, structure of the present utility model is described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
The 1 rustless steel nut that is provided in a side of the tail end of spiral nail body in the drawings, the 2nd, the missile wing packing ring, the 3rd, three wings cover nail, the 4th, spiral nail body, the front end of spiral nail body are the drill bit screw thread, the rear end is cylindric and a side lacks for circle, what tail end was connected with the nail body is square spiral shell button 5, and spiral nail body core is empty tubular core, and the circle that three wings cover nail 3 is socketed in spiral nail body rear end lacks on the post, the external diameter circumference of three wings cover nail is provided with three trianglees and protrudes sword, and its tail end is provided with a convex edge.
This utility model is at first directly screwed the spiral nail body the square spiral shell button 5 that is located at tail end and is made the Fracture of femur crack involutory fixing in use, then three wings cover nail be inserted on the spiral nail contract to the marrow in, fracture fixation is promptly finished in packing ring, nut fastening.
It is material that this utility model adopts rustless steel, has overcome the problem that three wing nail and spiral nail exist when treatment and resected femur bone, makes patient alleviate misery.
Claims (1)
1, a kind of pressurization spiral three wing nail, be by three wings cover nail 3, spiral nail body 4, spring washer 2 and nut 1 constitute, it is characterized in that: three wings cover nail 3 is the rear ends that are socketed in spiral nail body 4, the rear end of spiral nail body 4 is cylindric and one side lacks face for circle, and what tail end and nail bulk phase connect is a square spiral shell button 5.
