Abstract

The utility model discloses a pair of combined type bone holding forceps. The pair of combined type bone holding forceps comprises forceps handles, forceps arms, forceps heads on the forceps handles, 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, wherein the two forceps handles are straight rods, arc-shaped rods or S-shaped rods. The pair of combined type bone holding forceps is characterized in that an upper forceps arm and a lower forceps arm of the bone holding forceps are provided with completely-identical connectors capable of being connected with different types of replaceable forceps heads. Multiple alternative types are set for the pair of combined type bone holding forceps and can be selected according to the size and the shape of a bone and the catagmatic type, the positions of an upper forceps head and a lower forceps head can be exchanged, and the pair of combined type bone holding forceps is convenient to use and high in resetting efficiency. The forceps heads can be movable forceps heads and can be selected and adjusted according to the shaped of the bone so as to increase the contact area between the bone and the forceps heads and to enable clamping to be firm. A certain space for placing an internal fixation material is reserved between the clamping faces of the two forceps heads, and the problem that existing instruments are complicated in operation and lack of safety is solved. The clamping faces of the bone holding forceps are provided with meshy texture so that the clamped bone does not easily slip off.

Description

A kind of combination type bone holding forceps
Technical field
This utility model belongs to medical instruments field, specifically a kind of combination type 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 existing bone holding forceps apparatus similar with other, 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, easily cause 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 easily makes the horizontal slippage of bone holding forceps.4. existing bone holding forceps apparatus kind similar with other is more, but pattern and specification mostly compare fixed single, are difficult to tackle the dissimilar reduction of the fracture.
The utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and a kind of combination type bone holding forceps are provided, and these bone holding forceps have multiple alternative types binding clip, can select according to size shape and the type of fracture of bone, arbitrarily combination.
The technical scheme that realizes this utility model purpose is:
A kind of combination type bone holding forceps, comprise scalable screw rod and tong arm 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, two clamp handles are straight shape bar, bow or S type bar, unlike the prior art be: tong arm and lower tong arm have identical interface on the bone holding forceps, can connect dissimilar replaceable binding clip.
Described replaceable binding clip has oscillating type, spiketooth type, three fork-shaped universal types or arc type, and every kind of binding clip can be 1 or 2-3 of laterally being arranged in parallel.
The upper grip head of described combination type bone holding forceps and the clamping face of lower pliers head are provided with reticular texture, can arrange or not arrange pointed tooth.
Advantage of the present utility model:
1, the replaceable binding clip of these bone holding forceps is provided with multiple alternative types, can select according to size shape and the type of fracture of bone.Upper and lower binding clip capable of interchanging positions, all kinds binding clip can arbitrarily make up according to practical situation, and is easy to use, and the efficient that resets is high.
2, in the replaceable binding clip of these bone holding forceps, oscillating type and three fork-shaped universal types are movable binding clip, can select and regulate binding clip to increase contact surface with bone so that clamping is more firm according to the shape of bone during the clamping bone.
3, can arrange or not be provided with outstanding pointed tooth on the upper and lower binding clip of combination type bone holding forceps.Be reserved with the space of certain placement internal fixation material between two binding clip clamping faces, internal fixation material can be positioned over the correct position between two binding clip clamping faces as the case may be, has solved the loaded down with trivial details and full problem of feeling unwell of existing instrumentation.
4, these bone holding forceps clamping face all is provided with reticular texture, is difficult for occuring slippage during the clamping bone.
