Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in figure 1, the anti-skid minimally invasive multipoint reduction forceps comprise forceps bodies 1, wherein the two forceps bodies 1 are mutually crossed and are rotationally connected together through a rotating shaft, the front end of each forceps body 1 is provided with an arc-shaped embracing forceps opening 2, the rear end of each forceps body 1 is provided with a finger buckle 3, wherein,
the arc encircles 2 of keeping silent includes two kinds: firstly, the tail end of the arc-shaped embracing jaw 2 comprises a single-jaw tooth tip part 21; the tail end of the arc-shaped embracing jaw 2 comprises a forked clamp tooth tip part 22, and the forked clamp tooth tip part 22 is formed by forking a plurality of clamp tooth tip parts;
the single forceps tooth tip 21 and the forked forceps tooth tip 22 are respectively arranged on the two crossed forceps bodies 1.
As shown in fig. 4, the forked forceps tooth tip 22 is formed by bifurcating two forceps tooth tips and is used for clamping a bone, and a connecting line between the two forceps tooth tips on the forked forceps tooth tip 22 and the single forceps tooth tip 21 is in the shape of an isosceles triangle, with the two forceps tooth tips as two bases and the single forceps tooth tip 21 as a top; when clamping a bone, the forked clamp tooth tip part 22 encircles one side of the bone to form two fulcrums, the single clamp tooth tip part 21 encircles the other side of the bone to form one fulcrum, three fulcrums which are not on one line are formed in total, sliding is prevented, and clamping is accurate and firm.
As shown in fig. 5, the forked forceps tooth tip 22 is formed by three forceps tooth tips which are forked and used for clamping the bone plate, wherein the forceps tooth tip in the middle of the forked forceps tooth tip 22 is shorter than the forceps tooth tips at both sides to form a short forceps tooth tip and two long forceps tooth tips, and the connecting line of the short forceps tooth tip and the two long forceps tooth tips is in an isosceles triangle shape, the two long forceps tooth tips are used as two bases, and the short forceps tooth tip is used as a top; taking the bone plate as an example: as shown in fig. 6, two long forceps tooth tips of the forked forceps tooth tips 22 extend into the screw holes 9 of the bone plate 8, the short forceps tooth tips abut against the plate surface of the bone plate 8 to form three fulcrums, and then the three fulcrums are combined with the opposite single forceps tooth tips 21 to form four fulcrums with different lines in total, so that the clamping is firmer; as shown in fig. 7, two long forceps tooth tips of the forked forceps tooth tips 22 abut against the plate surface of the bone plate 8 to form two fulcrums, and then the opposite single forceps tooth tips 21 are combined to form three fulcrums with different lines in total, so that the clamping is firmer, and the short forceps tooth tips are suspended;
further, in a specific application of the embodiment, a small incision is cut at a fracture section, the bone plate 8 is close to the periosteum from the subcutaneous side and is parallel to the skeleton, the reduction forceps are respectively used for clamping the near end and the far end of the fracture from the skin, the tip part 21 of the single forceps tooth is used for fixing the skeleton, the tip part 22 of the forked forceps tooth is used for fixing the bone plate 8, the fracture end is pulled close to the bone plate 8 for reduction and fixation, and drilling and screw fixation are carried out after the position is good after a C-shaped arm X-ray fluoroscopy machine; in the above process, there are two cases:
the first situation is as follows: as shown in fig. 8, when the long forceps tooth tips at both sides of the bifurcated forceps tooth tip 22 of the reduction forceps are located at the screw holes 9 of the bone plate 8, since the long forceps tooth tips at both sides are longer than the middle short forceps tooth tip, the long forceps tooth tips can extend into the screw holes 9, so that the bone plate 8 is effectively prevented from rotating and shifting, and at this time, the middle short forceps tooth tip is located on the solid plate surface between the screw holes 9 at both sides, so that the bone plate 8 can be effectively clamped;
case two: as shown in fig. 9, when the long forceps teeth tips at both sides of the forked forceps teeth tip 22 of the reduction forceps are located on the solid plate surface of the bone fracture plate 8, at this time, the long forceps teeth tips at both sides of the forked forceps teeth tip 22 and the single forceps teeth tip 21 of the clamped bone end form an isosceles triangle stress surface, the fractured bone end is pulled close to the bone fracture plate 8 for reduction and fixation, and fixation is firm and not easy to loosen and slip, because the short forceps teeth tips in the middle of the forked forceps teeth tip 22 are shorter than the long forceps teeth tips at both sides, the middle short forceps teeth tips can be prevented from contacting the solid plate surface of the bone fracture plate 8 first, and formation of single teeth fixation is avoided.
The connecting line of two long forceps tooth tips in the forked forceps tooth tips 22 and the single forceps tooth tip 21 is in an isosceles triangle shape, the two long forceps tooth tips are used as two bottoms, and the single forceps tooth tip 21 is used as a top.
A clamp body buckle rack 4 is arranged on the clamp body 1 at the upper end of the finger buckle 3, the connection mode of the clamp body buckle rack 4 and the clamp body 1 comprises a fixed mode and a hinged mode, wherein,
fixed: as shown in fig. 3, one end of the clamp body fastening rack 4 is welded with the clamp body 1 or integrated into a whole to form a fixed clamp body fastening rack 41;
the articulated type: as shown in fig. 2, one end of the clamp body fastening rack 4 is rotatably disposed on the clamp body 1 through the rotating shaft 5, a limiting elastic sheet 6 is disposed above the clamp body fastening rack 4 for limiting the rotating height of the clamp body fastening rack 4, and the limiting elastic sheet 6 is fixedly connected to the clamp body 1 to form a hinged clamp body fastening rack 42;
the fixed clamp body buckling rack 41 and the hinged clamp body buckling rack 42 are respectively arranged on two crossed clamp bodies 1, the fixed clamp body buckling rack 41 and the hinged clamp body buckling rack 42 keep superposition along with the movement of the clamp bodies 1, and clamp body buckling teeth are respectively arranged on the contact surfaces of the fixed clamp body buckling rack 41 and the hinged clamp body buckling rack 42.
The fixed clamp body buckle rack 41 and the hinged clamp body buckle rack 42 are equal-diameter concentric arc sections.
The pliers body 1 is provided with a reinforcing section 7, and the rotating shaft 5 is arranged in the reinforcing section 7.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
