Abstract
The utility model relates to a bone grafting device, in particular to a distraction reduction bone grafting device for bone fracture, comprising a pliers-shaped main body formed by two handles which are hinged with each other through a pin shaft, a working end which is connected with the main body, and an adjusting screw rod is arranged between the two handles, one end of the adjusting screw rod is hinged with one of the handles, and the adjusting screw rod arranged between the two handles is provided with a reset spring, the side of the adjusting screw rod which stretches out of the other handle is provided with a nut, and the back end part of the handle is provided with an anti-skid elbow, and the axes of the working end and the axes of the main body form 90 DEG included angle, the connecting end of the working end and the main body and the end part of the main body form a funnel structure, and the outer surface of the working end part is provided with anti-skid teeth. The pliers-shaped main body is holded by the whole hand, and after the working end is inserted into a bone fracture end, the bone fracture end can be easily distracted, the anti-skid teeth at both sides of the working end and the adjusting screw rod distract the bone fracture end and keep stable, and working end and the main body form 90 DEG included angle, therefore, a bone block can be grafted into the bone fracture end through the funnel body of the working end.
Description
Technical field:
This utility model relates to a kind of bone grafting device, and the spy is a kind of fracture distraction reduction bone grafting device.
Background technology:
The fracture back is because the traction action of muscle makes the fracture end cripetura overlapping, or intercalation, needs during operative treatment fracture is retracted, and resets then or bone grafting.Dilator at present commonly used is straight type, appears insufficient, is not easy to the bone grafting operation, and back handle can only hold two fingers, and effort when strutting is not suitable for for more sturdy fracture.
Summary of the invention:
The deficiency that goal of the invention of the present utility model is to overcome background technology provides a kind of and can fully appear fracture end, and be convenient to fracture end and strut, reset and the bone grafting operation, and the fracture distraction reduction bone grafting device of rapid operation.
This utility model has the following technical scheme of employing:
A kind of fracture distraction reduction bone grafting device, comprise that two handles are the main body of tong-like structure by the hinged formation of bearing pin, the working end that is connected with main body, be provided with adjusting screw(rod) between described two handles, one end of this adjusting screw(rod) is with wherein one handle is hinged, place on the adjusting screw(rod) between two handles back-moving spring is housed, the side that this adjusting screw(rod) stretches out another handle is equipped with nut, described handle rear end portion is provided with anti-skidding elbow, be 90 ° of angles between the axis of its axis of described working end and main body, this working end is from being funnel-shaped structure with the link of main body to the end of its body, and the outer surface of this end, working end is provided with anti-slop serrations.
This utility model of employing technique scheme compared with prior art, its advantage is: the main body of holding its tong-like with full handgrip, behind its working end insertion fracture end, can strut fracture end more easily, be convenient to reset, be provided with adjusting screw(rod) between the anti-slop serrations of both sides, working end and two handles and fracture end can be strutted and keep stable, working end and main part are 90 ° of angles, can more easily the bone piece be implanted fracture end by the funnel-form of working end.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
The specific embodiment:
Below in conjunction with drawings and Examples in detail this utility model is described in detail:
