Description of reference numerals: 1. a fixing leg; 11. connecting the rotary groove; 12. fixing the jack; 13. a transfer groove; 14. a toothed surface; 2. a reset pin; 21. a hinged column; 22. a fork claw; 23. fixing the through hole; 3. a handle part.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the reduction forceps for the posterior cruciate ligament insertion avulsion fracture comprises a fixing foot 1 and a reduction foot 2 which are hinged and connected. The handle parts 3 used for rotation control are arranged at one ends of the fixed foot 1 and the reset foot 2, and are arranged in arc shapes, so that the reset pliers are suitable for being manually held, and the use comfort of the reset pliers is further improved. In addition, the purpose of driving the fixed leg 1 and the reset leg 2 which are connected in a hinged way to rotate can be achieved by controlling the rotation of the handle part 3. It should be mentioned that, on the fixing foot 1, a fixing member for fixing with the fractured end of the leg main body of the patient is provided, a resetting piece which is used for leading the torn bone block connected with the ligament to be abutted against the side surface of the resetting foot 2 close to one side of the fixing foot 1 after the ligament passes through is arranged on the resetting foot 2, further, when the operation of tearing off the bone block for reduction is carried out, the fixing foot 1 is fixed at the fracture end of the leg body of the patient by the fixing piece, the reduction foot 2 is opened, the ligament passes through the reduction piece to enable the torn off bone block to be abutted against one side of the reduction piece facing the fixing piece, the reduction foot 2 hinged with the fixing foot 1 is rotated, so that the reduction foot 2 moves towards the fixing foot 1 to achieve the purposes of moving the bone block and reducing the torn bone block, and the bone block is prevented from being cracked due to the clamping of the bone block, the phenomenon of secondary injury to a patient occurs, and the effective resetting difficulty and the operation risk of the torn bone block are obviously reduced.
It should be noted that the restoring member includes prongs 22 and a fixation aperture 23 through the restoring leg 2. The fork claw 22 is provided with a triangular clamping groove for the ligament to pass through and a fixing through hole 23 for the hollow nail guide needle to pass through to temporarily fix the reset bone block after the fork claw 22 resets the bone block. After the ligament passes the draw-in groove that is three horn shapes, tear and take off the bone piece and reset one side butt of piece orientation mounting, and then play the effect of supplying multiple different thickness ligaments to pass through the draw-in groove that is three horn shapes, make the tear of different shape sizes take off the bone piece homoenergetic effectively by the restriction in the one side that resets towards the mounting, thereby carry out effectual reseing to the bone piece that tears to take off, avoid the bone piece to burst and influence the effective treatment to the patient, and after the bone piece resets, make hollow nail guide pin pass and be located the fixed perforation 23 on the foot 2 that resets, thereby carry out effectual preliminary fixed to the bone piece, reduce and cut the position, reach the purpose of avoiding the vascular nerve damage. In order to further improve the effective limit of the fork claw 22 to the bone block, the fork claw 22 is further arranged to be arc-shaped and bent inwards, so that the bone block torn off by the inward bent fork claw 22 is effectively limited on one side of the resetting piece facing the fixing piece, and the bone block is prevented from being separated from the lower end of the fork claw 22 and the resetting foot 2, and the effective resetting of the bone block is prevented from being influenced. In order to further promote hollow nail guide pin insertion range and insert the angle, and then set up fixed perforation into the slot-like, and then the fixed perforation of slot-like supplies hollow nail guide pin to insert and takes off the bone piece to tearing of patient and fix, reaches the purpose that promotes the temporary fixation effect of guide pin to the bone piece.
As shown in fig. 1, the fixing member includes a fixing insertion hole 12 penetrating the fixing leg 1. Fixed needle will fix foot 1 and patient's shank main part fracture end department after passing fixed jack 12 and fix, and then when fixed foot 1, make fixed needle pass fixed jack 12 after fixed with patient's shank main part fracture end department fixed, the bone block that rethread rotation reset foot 2 will tear and take off resets, is convenient for operate this pincers that reset in a flexible way in effective space to carry out effectual treatment to the patient, show the security that promotes the operation. The lower extreme of fixed foot is provided with dentate face 14, and dentate face 14 sets up to the dogtooth that has, and then through dentate face 14 and patient's shank butt, and then further play the frictional force that increases between fixed foot and the patient, avoid fixed foot to rock on patient's leg and influence the effective restoration of foot to patient's bone piece that resets.
It should be mentioned that the fixing foot 1 is provided with an adapter slot 13 for the reset foot 2 to pass through and connecting slots 11 on both sides of the adapter slot 13. The reset foot 2 is provided with a hinge column 21 inserted into the connecting rotary groove 11, and when the reset foot 2 rotates relative to the fixed foot 1, the reset foot 2 rotates relative to the fixed foot 1 by taking the hinge column 21 as an axis. And the foot 2 that resets is after passing the switching groove 13 on fixed foot 1, makes the foot 2 that resets and fixed foot 1 form stable connection structure, thereby the articulated post 21 on the foot 2 that resets inserts the rotational stability that the foot 2 that resets is thereby further promoted in the switching groove 13 internal rotation, thereby will reach the purpose that further promotes the accuracy that resets when the bone piece that tears the patient through the foot 2 that resets and take off resets, show the practicality that promotes this pincers that reset in the operation of fracture is torn to the cruciate ligament stop at back.
The above is only the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiments, but all the cases belong to the technical solution of the present invention under the thought all belong to the protection scope of the present invention. It should be noted that modifications and decorations, which would occur to those skilled in the art without departing from the principle of the present invention, should also be considered as the protection scope of the present invention.
