Detailed ways

The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to Figures 1 to 4, the self-locking resetting forceps in this embodiment include the first forceps body 200 and the second forceps body 300 intersected by the cheek screw 100 and the first forceps body 200 and the second forceps body. The self-locking mechanism 400 between the two pliers 300, the self-locking mechanism 400 includes a rack 410, a spring leaf 420 and a locking block 430, the rack 410 and the spring leaf 420 are arc-shaped structures, and the inner wall of the rack 410 protrudes There are teeth, one end of the rack 410 is hinged to the first pliers body 200, one end of the spring leaf 420 is fixed to the first pliers body 200 by a screw, and the end of the spring leaf 420 facing away from the screw is provided with a bending part 421, and the bending part 421 is provided with a bending part 421. There is a chute, and the rack 410 is slidably arranged in the chute, and one end of the locking block 430 is pinned to the second pliers body 300, and a locking groove 431 is provided in the locking block 430, and the rack 410 can slide or lock on the Locking groove 431 .

In this technical solution, the self-locking resetting forceps described in the present invention are easy to operate, and the medical staff can complete the self-locking action with one hand, which shortens the operation time and relieves the pain of the patient. Under the action of the elastic force of the plate, the self-locking reset forceps are in a free state. Hold the first forceps body and the second forceps body to align the two ends of the fracture, push the locking block with your thumb, and the locking block is locked with the rack. The locking reduction forceps are in a locked state, and the fracture end is reset. After the plate and screw are fixed, the locking block is released, and the self-locking reduction forceps is removed.

Further, the first pliers body 200 includes a first pliers handle 210 , a first hinge part 220 and a first pliers tip 230 , and the second pliers body 300 includes a second pliers handle 310 , a second hinge part 320 and a second pliers tip 330 , the first hinged part 220 and the second hinged part 320 are hinged by the cheek screw 100, the inner wall of the first pliers handle 210 is provided with a first cavity 240, and one end of the rack 410 is pinned in the first cavity, and the second pliers The inner wall of the handle 310 is recessed with a second cavity 340 , and one end of the locking block 430 is pinned in the second cavity.

In this technical solution, it is ensured that the self-locking mechanism is located between the first pliers body and the second pliers body as a whole, so as to avoid affecting the comfort of medical staff after protruding from the first pliers body and the second pliers body

Furthermore, the bending portion 421 is in an arc shape, and the end of the rack 410 close to the pin connection is provided with a round pin 411 , and the round pin 411 is attached to the inner wall of the bending portion 421 .

In this technical solution, when the rack rotates around its pin joint end, a force is applied to the spring piece through the round pin, so that when the locking block is opened, under the action of the spring force of the spring piece, a force is applied to the rack, so that the self-locking Type reset clamp is in free state.

Further, the length of the round pin 411 is greater than the width of the slide slot.

In this technical solution, it is avoided that the round pin 411 passes through the sliding groove, thereby losing the force of the spring leaf on the rack.

Further, a long waist hole 432 is provided at the bottom of the locking block 430 , and the locking block 430 is pinned into the second cavity through the long waist hole 432 .

Further, a locking portion 433 corresponding to the teeth protrudes from the top of the locking groove 431 .

In the above technical solution, the locking block 430 is pinned into the second cavity through the long waist hole 432. During the rotation of the locking block, the locking part resists or disengages between the teeth to complete the self-locking Self-locking or releasing of type reset clamp

Further, the outer walls of the first pliers handle 210 and the second pliers handle 310 are concavely provided with anti-slip lines.

In this technical solution, the friction force between the hand of the medical staff and the self-locking resetting forceps is increased, which is convenient for taking and using.

Further, the end of the first forceps tip 230 is connected with a first forceps piece 231 , the end of the second forceps tip 330 is connected with a second forceps piece 331 , and the first forceps piece is opposite to the second forceps piece in an encircling arrangement.

In this technical solution, the first forceps piece and the second forceps piece are respectively fixed to the ends of the first forceps tip and the second forceps tip by welding.

Further, the end of the first forceps 231 is processed with a first point, and the end of the second forceps 331 is processed with a second point.

In this technical solution, the first pointed part and the second pointed part can directly or indirectly reset the broken bone, and the damage to the periosteum is slight.

To sum up, the self-locking resetting forceps of the present invention are easy to operate, and the medical staff can complete the self-locking action with one hand, which shortens the operation time and relieves the pain of the patient.
