Description

A kind of orthopedic reduction forceps with the function of stabilizing steel plates

technical field

The utility model relates to an orthopedic reset forceps with the function of stabilizing steel plates, which belongs to the technical field of medical instruments.

Background technique

Orthopedic reduction forceps are used in orthopedic surgery, especially in fracture surgery, to expose the broken end of the fracture, clean up the tissue between the broken ends, and use the reduction forceps to reset. After the alignment is good, the reduction forceps are fixed, and then Kirschner wires, steel plates, Intramedullary nails or other internal fixation devices are used for fixation, but traditional fracture reduction forceps often cause certain obstacles to the placement of the steel plate when the fracture is reduced and fixed.

Contents of the invention

The purpose of the utility model is to provide an orthopedic reset forceps with the function of stabilizing the steel plate to solve the technical problem that the reset forceps in the prior art hinder the placement of the steel plates.

The technical solution adopted by the utility model is: a kind of orthopedic reset forceps with the function of stabilizing the steel plate, including two forceps bodies hinged together by pin shafts in the middle, the front end of the forceps body is the jaw, and the rear end of the forceps body is the forceps arm. Two arc-shaped fixing rods are respectively provided at the ends of the jaws, and the arc-shaped fixing rods are bent inwardly, and a straight-type fixing rod is arranged inside the pin shaft, and the straight-type fixing rod is threaded inside the pin shaft, One end of the straight fixed rod is located between the two jaws, and the other end is located between the two arms.

Preferably, the front ends of the arc-shaped fixing rod and the straight fixing rod are both provided with a ball head, and the top of the ball head is provided with a pointed end.

Preferably, a safety insurance is provided between the two pliers arms.

The beneficial effects of the utility model are: the utility model changes the prior art pliers head into an arc-shaped fixing rod, which provides convenience for the medical staff to place the steel plate, and the four arc-shaped fixing rods can fix the bone injury without affecting the fractured part , and does not affect the placement of the steel plate, the straight fixed rod is fixed in the pin shaft through threads and the up and down position of the straight fixed rod can be controlled by rotation, which provides convenience for placing the steel plate, placing the steel plate on the straight fixed rod and bone In between, the steel plate is fixed closely to the bone by rotating the straight fixing rod, which can effectively reduce the operation time and operation difficulty, and also reduce the patient’s discomfort caused by the long-term operation.

Furthermore, the ball head can prevent the tip of the arc-shaped and straight-shaped fixation rod from being inserted into the bone too deeply, and can also increase the friction coefficient between the forceps body and the bone, which can fix the wound more stably, and can be applied to larger In small orthopedic surgery, the scope of application is more flexible.

Furthermore, the medical staff need to push the safety cover to pinch the two forceps arms, which avoids misoperation during the operation, ensures that the medical staff can operate more accurately, and ensures the patient's surgical safety.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the orthopedic reduction forceps with the function of stabilizing the steel plate in this embodiment includes two forceps bodies hinged together by pin shafts in the middle, the front end of the forceps body is the jaw 6, and the rear end of the forceps body is the forceps arm 4, The ends of each pliers mouth 6 are respectively provided with two arc-shaped fixed rods 2, the arc-shaped fixed rods 2 are bent inwardly, and a straight fixed rod 3 is arranged inside the pin shaft, and the straight fixed rod 3 is threaded through Installed inside the pin shaft, one end of the straight fixed rod 3 is located between the two pliers mouths 6 , and the other end is located between the two pliers arms 4 . The front ends of the arc-shaped fixed rod 2 and the straight fixed rod 3 are all provided with a ball head 1, and the top of the ball head is provided with a tip. A safety fuse 5 is provided between the two tong arms.

The use process of this embodiment is as follows: during the operation of orthopedic reduction, first place the orthopedic reduction forceps on the area that needs to be operated on, and fix the arc-shaped fixing rods on both sides of the wound respectively. After pushing the safety insurance, knead the two Clamp arm, insert the steel plate between the straight fixation rod and the bone at this time, rotate the straight fixation rod after confirming the position, the straight fixation rod pushes the steel plate to the bone until it fits closely, and the medical staff can perform the next step of fixation operate.

In this embodiment, the pliers head of the prior art is changed to an arc-shaped fixing rod, which provides convenience for the medical staff to place the steel plate. The four arc-shaped fixing rods can fix the bone injury without affecting the fracture site, and do not affect the placement of the steel plate. The straight fixation rod is fixed in the pin shaft by thread and the up and down position of the straight fixation rod can be controlled by rotation, which provides convenience for placing the steel plate, the steel plate is placed between the straight fixation rod and the bone, and fixed by rotating the straight The rod tightly fixes the steel plate on the bone, which can effectively reduce the operation time and operation difficulty, and can also reduce the patient's discomfort caused by the long-term operation. The ball head can prevent the tip of the arc-shaped and straight-shaped fixation rod from being inserted into the bone too deeply, and can also increase the friction coefficient between the forceps body and the bone, which can fix the wound more stably, and can be applied to minor orthopedic operations , making the scope of application more flexible. The medical staff need to push the safety cover to pinch the two forceps arms, which avoids misoperation during the operation, ensures that the medical staff can operate more accurately, and guarantees the patient's surgical safety.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those of ordinary skill in the art should understand that the above-mentioned embodiments do not limit the protection scope of the present utility model in any form, and all technical solutions obtained by means of equivalent replacement all fall within the protection scope of the present utility model.
