Abstract

Provided is a jaws fixing device with a nail puncturing through comprising jaws[1] and a handle[2]. The handle[2] is provided with a handle fixing bolt. A steel wire fixing mechanism is arranged correspondingly on the two jaws. The sleeve[7]on the steel wire fixing mechanism is installed with a location screw[6]. The sleeve[7]is installed with a steel wire[8]. The tips of the steel wires on the two jaws oppose to each other face to face. The utility model with a reasonable design conducts fixation through the cooperation between the steel wire and the jaws to fully perform the fixation function of clamp and press. Therefore, the utility model with nice stability and fine location effect can prevent displacement of the fracture part and is favorable for patients to recover. The utility model with a simple structure is convenient to use and is a practical orthopaedics medical instrument.

Description

Drift bolt formula clamp holder

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of drift bolt formula clamp holder that is used for fixing the oblique or spiral fracture of extremity tubular bone.

Background technology

Oblique or the spiral fracture of extremity tubular bone very clinically more sees that belong to unstable fracture, fixing means generally has three kinds, and first method is that the fracture behind the operative reduction is fixed with Gypsum Fibrosum or clamping plate, but insecure, fracture is shifted easily; Second method is the open reduction internal fixation, and the method can make the accurate para-position of fracture, fixation, but damage is big, need carry out the operation second time after the union of fracture and take out inside-fixture, increases patient's misery and financial burden; The third method is to adopt exterior fixation bracket to fix, this kind method complicated operation hindering limb many places perforation nailing, does not have direct reinforcement effect to fracture end, but by the outer pressure pad of skin indirectly to the fracture end pressurization, therefore fixing insecure to oblique or spiral fracture.

Bonesetting hospital in Luoyang pays the clamp holder of the auspicious design of light, though on the oblique or spiral fracture that is used for the extremity tubular bone fixing, improve to some extent, and it is simple in structure, to use easy to operately, clamping is strong, can make the good para-position of fracture end acquisition.But because the skin of extremity tubular bone is cortical bone, harder, the tubular bone periphery is relatively slicker and more sly, and the tip of this clamp holder can't be pressed in the cortical bone when clamping, and causing often has looseningly, fixing not firm during treating, and fracture end can be shifted again.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved drift bolt formula clamp holder is provided, and improves clamping stability and locating effect, prevents the fracture end displacement, helps patients ' recovery.

The purpose of this utility model can realize by following technical measures: this holder has clamp, handle, before its pin joint is clamp, the back is a handle, handle is equipped with the handle gim peg, be the bolt and nut structure, screw rod cooperates with nut does the handle location, be arranged with the draw point fixed mechanism at two clamps, the draw point fixed mechanism preferably is located on the clamp two-port, the draw point fixed mechanism is a casing location device, and set screw is housed on the sleeve pipe, and draw point is housed in the sleeve pipe, draw point is by the set screw fixed position, and the draw point tip on two clamps aligns mutually.

During use, two pieces of draw points are separately fixed on the draw point fixed mechanism of two clamps, about 0.5cm is inwardly exposed at the draw point tip, fracture end is carried out conventional manual reduction, make the fracture end para-position, choose needle point and thrust a little, exert pressure then needle point is thrust to bony surface, unclamp one piece of draw point set screw afterwards, this draw point is penetrated a side seam cortex, fix this piece draw point again with bone drill.With another piece draw point being penetrated in the opposite side cortical bone with quadrat method.Firmly clamping makes fracture end obtain to stablize, and tightens the handle gim peg, removes the handle extension arm, finishes as conventional treatment.

This utility model is reasonable in design, utilizes draw point and clamp to cooperate and fixes, and gives full play to clamping pressurization fixation, clamping stability and good positioning effect prevent the fracture end displacement, help patients ' recovery, and simple in structure, easy to use, be practical orthopedic medical device.

Description of drawings

Fig. 1 is a structure chart of the present utility model.

The specific embodiment

With reference to Fig. 1, there is clamp [1] on this holder pin joint both sides, handle [2], there is the handle extension arm [5] of loose joint formula handle [2] rear end, handle [2] is equipped with the handle gim peg, be the bolt and nut structure, screw rod [3] one ends be hinged on one side handle [2] lining to, the other end passes another side handle [2] perforate and cooperates with nut [4], adjusting nut [4] is done the handle location, and there is bayonet socket handle [2] rear end, and the handle extension arm has bayonet lock on [5], bayonet socket and bayonet lock cooperatively interact to connect and add long handle, symmetry is equipped with the draw point fixed mechanism on two clamps [1] port, and two set screws [6] are housed on the sleeve pipe of draw point fixed mechanism [7], and draw point [8] is housed in the sleeve pipe [7], draw point [8] adopts Kirschner wire, by set screw [6] fixed position, and can use bone drill to puncture, draw point [8] tip on two clamps [1] aligns mutually.

Claims

1, a kind of drift bolt formula clamp holder, clamp [1], handle [2] are arranged, handle [2] is equipped with the handle gim peg, it is characterized in that two clamps [1] are arranged with the draw point fixed mechanism, set screw [6] is housed on the sleeve pipe of draw point fixed mechanism [7], draw point [8] is housed in the sleeve pipe [7], and the draw point tip on two clamps aligns mutually.
