Multifunctional resetting and fixing guide pliers

Abstract

The invention discloses a pair of multifunctional resetting and fixing guide pliers, comprising an upper pliers arm, a lower pliers arm, a lower pliers head, an upper pliers head and handles, wherein the upper pliers arm and the lower pliers arm are articulated with the lower pliers head and the upper pliers head; the handles are respectively arranged on the upper pliers arm and the lower pliers arm; an upper guide device and a lower guide device are respectively arranged on the upper pliers head and the lower pliers head; and the upper guide device and the lower guide device are arranged in one-to-one correspondence. According to the invention, the guide devices are arranged on the pliers heads of the guide pliers so as to achieve the aim of positioning; as the guide devices are arranged in one-to-one correspondence, in a drilling process, the upper and lower guide devices can be directly aligned, so that fixation needles can be accurately drilled for fixing and resetting; hole diameters of the guide holes can be in different specifications so as to adapt to fixation needles in different thicknesses; and the upper pliers head and the lower pliers head are fastened to form a ring structure, and the inner diameter of the ring structure can be in different specifications so as to adapt to clamping of bones in different parts.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a multifunctional repositioning and fixing guide forceps with simple structure and convenient operation. Background technique [0002] After reduction of small fracture fragments or oblique fractures of tubular bones, when the fracture fragments are small, the reduction forceps often occupy the fixed drilling position and cannot be drilled. The reduction forceps must be loosened again to prolong the operation time. In addition, most medical staff use Kirschner wires are used as internal fixation or as guide wires for surgery. However, when performing this operation, it is difficult for the medical staff to ensure the accuracy of the needle insertion and withdrawal, and it is easy for the Kirschner wire to deviate from the intended target, which leads to the failure of the operation. Now medical personnel use a drilling directional device to assist in implan...

AI Technical Summary

Problems solved by technology

[0002] After the reduction of small fracture fragments or oblique fractures of tubular bones, when the fracture fragments are small, the reduction forceps often occupy the fixed drilling position and cannot be drilled. The reduction forceps must be loosened again to prolong the operation time. In addition, most medical staff use Kirschner wires as internal fixation or as guide wires for surgery

However, when performing this operation, it is difficult for the medical staff to ensure the accuracy of the needle insertion and withdrawal, and it is easy for the Kirschner wire to deviate from the intended target, resulting in the failure of the operation

Now medical personnel use a drilling directional device to assist in implanting Kirschner wires. The directional device includes a horizontal directional rod and a vertical directional rod that are slidably connected together. There is a support rod whose end is adapted to the needle insertion base, but its disadvantages are 1. When different types of Kirschner wires need to be implanted, different types of needle insertion bases are required, so it is extremely inconvenient to use; 2. The support rod and The distance between the horizontal orientation rods is not adjustable, so it cannot be applied to different parts of the Kirschner wire implantation
