Description
Technical field
This utility model relates to orthopaedic medical treatment apparatus, a kind of three jaws bone holding forceps.
Background technology
During bone surgery, it is often necessary to use three-jaw bone holding forceps and the fracture site that long bone is key is captured, resets and fixes temporarily.Common two, three-jaw bone holding forceps front end pawl is all fixed from activity, three-jaw bone holding forceps are also only applicable to long bone shaft fracture reset and grip, as some privileged sites such as intertrochanteric fracture, then cannot grip, thus cause the problems such as complicated, incomplete, the poor stability of reduction by traction operation.
Utility model content
The purpose of this utility model is to provide a kind of three jaws bone holding forceps, has solved existing common three-jaw bone holding forceps and has been unsuitable for the problem gripped of privileged sites such as intertrochanteric fracture.
The purpose of this utility model is achieved in that
A kind of three jaws bone holding forceps, include slide body, the first movable claw, the second movable claw, adjusting screw rod, clamp jaw and lock-screw；
Described slide body is respectively equipped with the first chute and the second chute；It is provided with the first bending in the upper end of described slide body, and is provided with regulation screw in described first bending；It is respectively provided with a locking screw holes in the both sides, lower end of described slide body；
Described first movable claw and described second movable claw are installed on two described locking screw holes by aerofoil profile bolt respectively；
Described clamp jaw is made up of fastening part and clamping part, and the upper end of described fastening part is provided with the second bending, is provided with spacing hole in described second bending, and the lower end of described fastening part connects clamping part；The upper end, side of described fastening part is installed at described second chute by a stop screw, and the lower end, side of described fastening part is installed at described first chute by described lock-screw；
Described adjusting screw rod is rotatably connected in the regulation screw on described slide body, and its lower end is plugged in the spacing hole on described clamp jaw.
Described three jaws bone holding forceps, are provided with the first Kirschner wire pilot hole on described adjusting screw rod, are provided with the second Kirschner wire pilot hole on described clamp jaw, and described first Kirschner wire pilot hole and described second Kirschner wire pilot hole are coaxially disposed and equal diameters.
The first two gripper jaw of the present utility model is movable (the i.e. first movable claw and the second movable claw), its angle can be adjusted as required, to meet bone type requirement, be particularly suitable for the situation of intertrochanteric fracture, it is to avoid the traditional reduction by traction operation of intertrochanteric fracture is complicated, not exclusively, the problem such as poor stability.Further, this utility model is additionally provided with Kirschner wire pilot hole, conveniently needs to beat fracture Kirschner wire, the operation such as is fixed.

In figure: 1, slide body, 2, clamp jaw, the 3, first movable claw, 4, the second movable claw, 5, lock-screw, the 6, first chute, 7, adjusting screw rod, the 8, first Kirschner wire pilot hole, the 9, second chute, 10, aerofoil profile bolt, 11, stop screw, 12, regulation screw, 13, spacing hole, 14, fastening part, 15, clamping part, 16, the first bending, the 17, second bending, the 18, second Kirschner wire pilot hole.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, these bone holding forceps are made up of slide body the 1, first movable claw the 3, second movable claw 4, adjusting screw rod 7, clamp jaw 2 and lock-screw 5 etc..
Slide body 1 is respectively equipped with the first chute 6 and the second chute 9；It is provided with the first bending 16 in the upper end of slide body 1, and in the first bending 16, is provided with regulation screw 12；It is respectively provided with a locking screw holes in the both sides, lower end of slide body 1.
First movable claw 3 and the second movable claw 4 are installed on two locking screw holes of both sides, slide body 1 lower end by aerofoil profile bolt 10 respectively.
Clamp jaw 2 is made up of fastening part 14 and clamping part 15, and the upper end of fastening part 14 is provided with the second bending 17, is provided with spacing hole 13 in the second bending 17, and the lower end of fastening part 14 connects clamping part 15；Meanwhile, the upper side of fastening part 14 is installed at the second chute 9 by a stop screw 11, and the lower end side of fastening part 14 is installed at the first chute 6 by lock-screw 5.
Adjusting screw rod 7 is rotatably connected in the regulation screw 12 on slide body 1, and its lower end is plugged in the spacing hole 13 on clamp jaw 2.
Additionally, and being respectively equipped with the first Kirschner wire pilot hole 8 and the second Kirschner wire pilot hole 18 on clamp jaw 2 on the central axis of adjusting screw rod 7, the second Kirschner wire pilot hole 18 on clamp jaw 2 is coaxially disposed and equal diameters with the first Kirschner wire pilot hole 8 on adjusting screw rod 7.
These bone holding forceps are in use, first by wing bolt 10, lock-screw 5 unscrews, then turn adjusting screw rod 7, adjust position and first movable claw 3 of clamp jaw 2, the angle of the second movable claw 4, make bone holding forceps can enter fracture area smoothly, and make it match with fracture region skeleton, first locking wing bolt 10, fix the first movable claw 3 and angle of the second movable claw 4, then turn adjusting screw rod 7 and lock-screw 5 make clamp jaw 2 clamp fracture region skeleton, with ensure reset after fracture region fix without departing from, if needing to beat Kirschner wire skeleton is fixed, then can squeeze into Kirschner wire by the first Kirschner wire pilot hole 8 and the second Kirschner wire pilot hole 18.
