Abstract
The utility model discloses a pair of swing head type bone holding forceps. The pair of swing head type bone holding forceps comprises forceps handles, forceps arms, forceps heads, an X-shaped forceps body formed by cross-connecting the forceps handles, the forceps arms and the forceps heads, a movable main joint on the forceps body and adjustable screws on the forceps handles. The pair of swing head type bone holding forceps is characterized in that an upper forceps head and a lower forceps head are asymmetric, the lower forceps head is arc-shaped, a swing forceps head is connected onto an upper lower forceps arm, the clamping faces of the swing head type bone holding forceps are provided with meshy texture, and the bone holding forceps can be provided with sharp teeth or be not provided with the sharp teeth. The pair of swing head type bone holding forceps has the advantages that the two forceps heads of the bone holding forceps are asymmetric, the forceps arms can be adjusted according to the shape of a bone in clamping so as to increase the contact faces between the bone and the forceps arms and to enable the clamping to be firm. Two protruded sharp teeth can be arranged on the forceps heads and can enable the clamped bone fracture end to be firm. A space for placing an internal fixation material is reserved between the clamping faces of the two forceps heads, the sharp teeth can penetrate through screw holes of the internal fixation material to place the internal fixation material on the bone surface, the internal fixation material can also be placed at the other appropriate positions between the clamping faces of the two forceps heads according to specific situations, and the problem that existing instruments are complicated in operation and lack of safety is solved. The clamping faces are provided with the meshy texture so that the clamped bone does not easily displace.
Description
Technical field
This utility model belongs to medical instruments field, specifically a kind of pendulum
HeadThe formula bone holding forceps.
Background technology
Fracture is one of modal disease of orthopaedics.At present, in the fracture internal fixation operation of cutting and resetting, reset through the apparatus clampings such as bone holding forceps commonly used two broken ends of fractured bone of fracturing, then be fixed with internal fixation material.But because size shape and the classification of fracture of bone are different, there are many problems in the similar apparatus with other of existing bone holding forceps, is difficult to satisfy the needs of operation.Wherein main defective has: 1. the profile of bone is general and irregular, it is the fixing arcuation jaw of full symmetric that part bone holder tool adopts clamping place, limited with the contact surface of bone, this type of apparatus is the often slippage owing to clamping bone shakiness in clinical operation, cause fracture end stab peripheral vessels nerve and soft tissue, cause easily serious malpractice.2. jaw is not reserved the space of placing internal fixation material, particularly also needs bone holding forceps are unclamped during implant plate, and again clamping behind implant plate easily causes the fracture malreduction.3. the bone holding forceps band design parallel with long bone with the normal employing in bone contact position makes the horizontal slippage of bone holding forceps easily.
The utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and a kind of pendulum is provided
HeadThe formula bone holding forceps.
The technical scheme that realizes this utility model purpose is:
A kind of pendulum
HeadThe formula bone holding forceps, comprise the scalable screw rod on the mobilizable main joint and clamp handle on the X-type caliper, caliper of clamp handle, tong arm, binding clip and crosslinked composition thereof, unlike the prior art be: two binding clips of bone holding forceps are asymmetric, lower pliers head is arc, be connected with on the upper tong arm and can swing binding clip, the clamping face of bone holding forceps is provided with reticular texture, arranges or do not arrange pointed tooth.
Described to swing binding clip curved, and its center is arranged on the axle of a bindiny mechanism, can swing binding clip and can swing certain amplitude around axle, can swing binding clip and be connected on the tong arm.
Described lower pliers head is 1 or the 2-3 that laterally is arranged in parallel, forms curved groove shape.
The described binding clip that swings is 1 or the 2-3 that laterally is arranged in parallel.
Advantage of the present utility model:
1, these bone holding forceps two binding clips are asymmetric: lower pliers head is arc, and upper tong arm is connected with and can swings binding clip, can be according to the shape adjustment binding clip of bone to increase contact surface with bone so that clamping is more firm during the clamping bone.
2, can swing two or several outstanding pointed tooths can be set on the binding clip.Be reserved with the space of placing internal fixation material between two binding clips between clamping face, internal fixation material can pass its screw hole by pointed tooth and be positioned over surface of bone, also can be positioned over as the case may be other correct positions between two binding clip clamping faces, solve the loaded down with trivial details and full problem of feeling unwell of existing instrumentation.
3, oscillating type bone holding forceps clamping face all is provided with reticular texture, is difficult for during the clamping bone being shifted.
