Description

Quick steel plate homing fracture forceps

Technical Field

The utility model relates to the field of medical appliances, in particular to a pair of rapid steel plate homing fracture forceps.

Background

In fracture surgery, reduction of fracture is the first step of treatment and the most important step in the whole treatment, how to fix the restored fractured bone under stable condition often needs to be operated by fracture reduction forceps, but various reduction forceps used by people all the time and all documents including patents which are not converted into products exist that the reduction forceps fix steel plates and shield the fracture part or shield the operation space. Although some instruments can avoid shielding to a certain extent, the phenomenon that bones slip to the root part exists during pressurization, and the significance of using the reduction forceps is lost. Some bone holding forceps have designed arcuation tong jaw to solve and have skidded, still do not vacate and place the steel sheet space on the skeleton, and from the whole straight pincers body design of handle to claw, can't solve at the fixed in-process that resets, the hand of holding the pincers that reset certainly shelters from the problem of the other hand of operation electric drill, prior art is to hold contralateral bone piece with traditional pincers that reset and resets, simultaneously is wearing the steel wire with the steel wire director, tie up the steel wire, operation wound space is big, the steel wire bundle can't arrive the bone piece center. When a traditional steel plate is placed, the bone holding forceps need to be loosened, and multiple times of dislocation can be caused to spliced broken bones.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that needs to solve is overcome above-mentioned prior art not enough, provides one kind and can make the fracture after reseing keep carrying out the steel sheet internal fixation under the stable condition, conveniently with the steel wire around on the garrulous bone piece, the quick steel sheet playback fracture pincers that swiftly put into the steel sheet simultaneously.

In order to realize the purpose, the utility model provides a technical scheme is:

the utility model provides a quick steel sheet playback fracture pincers, including pincers piece A and pincers piece B, pincers piece A and pincers piece B (6) are through the crisscross articulated pin, use the pin as the border, pincers piece A front end constitutes binding clip A rear end and constitutes pincers handle A, pincers piece B front end constitutes binding clip B rear end and constitutes pincers handle B, binding clip A and binding clip B relative bending and constitute the keeping silent of centre gripping disconnected bone, the arc wall has been seted up along binding clip A's crooked direction on binding clip A and the relative cambered surface of binding clip B, it is provided with a plurality of screws rather than threaded connection to prolong its crooked direction equipartition on binding clip B.

Specifically, the number of the screws is at least three.

Specifically, the screw is a large-pitch screw.

Specifically, the cambered surface of the binding clip A opposite to the binding clip B is provided with anti-skid lines.

Specifically, the end face, facing the binding clip A, of the screw is provided with anti-skidding threads.

Specifically, the clamp handle A is hinged with a screw rod, the screw rod penetrates through a long slotted hole in the clamp handle B, and the screw rod is in threaded connection with a nut for extruding the clamp handle B.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, simple structure, convenient operation, the pincers that reset hold the offside bone piece back that resets, and the steel wire passes from the pincers arc wall that resets, can make things convenient for the steel wire to directly tie up the bone piece around the bone piece, when placing the steel sheet, lets out the mounted position of steel sheet through the screw that becomes flexible binding clip B mid portion to be convenient for place the steel sheet, guarantee when placing the steel sheet, binding clip A has the clamping action to the broken bone that the concatenation is good all the time with binding clip B, broken bone many times dislocation when preventing to place the steel sheet.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural view of the pliers head a of the present invention after being thrown away.

Part names in the drawings are as follows:

1. the pliers comprise pliers handles B and 2, pliers handles A and 3, pins 4, pliers heads A and 5, pliers heads B and 6, pliers sheets B and 7, an arc-shaped groove 8, a screw rod 9, a long groove hole 10, a nut 11, a screw 12 and pliers sheets A.

Detailed Description

As shown in fig. 1-2, a quick steel plate homing fracture forceps comprises a forceps sheet a12 and a forceps sheet B6, the forceps sheet a12 and the forceps sheet B6 are hinged in a staggered manner by a pin 3, the pin 3 is used as a boundary, the front end of the forceps sheet a12 forms the rear end of a forceps head A4 to form a forceps handle a2, the front end of the forceps sheet B6 forms the rear end of a forceps head B5 to form a forceps handle B1, the arc surface of the forceps head A4 opposite to the forceps head B5 is provided with anti-slip threads, the forceps handle a2 is hinged with a screw rod 8, the screw rod 8 passes through a long groove hole 9 on the forceps handle B1, the screw rod 8 is in threaded connection with a nut 10 for extruding the forceps handle B1, the forceps head A4 and the forceps head B5 are bent oppositely to form a screw for clamping a broken bone, the arc surface of the forceps head A4 opposite to the forceps head B5 is provided with an arc-shaped groove 7 along the bending direction of the forceps head A4, the bending direction of the forceps head B5 is provided with a plurality of screws uniformly distributed along the bending direction, and at, the end face of the screw 11 facing the forceps head A4 is provided with anti-slip threads.

When in use, after the doctor cuts skin to separate muscle and expose the broken bone, the doctor properly peels off the bone surface where the steel plate is placed, the two broken ends do not need to peel off and destroy periosteum circularly in a long distance, the blood clot at the broken ends of the fracture is thoroughly cleared, the fracture is restored by means of two rapid steel plate homing fracture forceps, the head A4 and the head B5 of the rapid steel plate homing fracture forceps clamp the broken bone, the handle A2 and the handle B1 are tightened, the nut 10 is screwed, the two rapid steel plate homing fracture forceps are used for respectively clamping the broken ends of the fracture relatively close to each other, so that the broken ends of the bone are butted together, the fracture reduction condition is observed by a C-arm X-ray machine, after the fracture alignment is good, the screw 11 in the middle of the head B5 is loosened to keep away from the broken bone, at the moment, the screws 11 at the two ends of the head B5 clamp the broken bone all the time, so as to ensure that the broken bone after the reduction can keep, the screw 11 in the middle of the binding clip B5 is far away from the broken bone to leave the space for installing the steel plate, at the moment, the steel plate passes through the screw 11 in the middle of the binding clip B5 to be far away from the space left by the broken bone, and then the steel plate is fixed on the broken bone, the whole operation can be completed under the state that the steel plate is rapidly restored to the fixation of the fracture clamp, the clamping position does not need to be changed midway, the operation procedure is simplified, the operation time is shortened,

when the fragments of the fracture on the opposite side are reset and bound, one end of a steel wire or a fretsaw is used for penetrating into the arc-shaped groove 7, the steel wire or the fretsaw can penetrate through the fragments of the fracture along the arc-shaped groove 7 due to certain rigidity of the steel wire or the fretsaw, after one end of the steel wire or the fretsaw penetrates out of the arc-shaped groove 7, one end of the steel wire or the fretsaw is pulled out by using the clamp, and the fragments of the fracture on the opposite side can be directly bound by the.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
