Embodiment Construction

[0041] A kind of Kirschner wire surgical forceps, such as Figure 1-11It includes two cheek rotating parts that rotate relatively, the cheek rotating part I101 and the cheek rotating part II102, the cheek rotating part I101 and the cheek rotating part II102 protrude from one end to the clamp head I201 and the clamp head II202 respectively, and the clamp head I201 It forms the opening and closing jaw 260 together with the pliers head II 202; the cheek rotating part Ⅰ 101 and the cheek rotating part Ⅱ 102 respectively protrude the handle Ⅰ 301 and the handle Ⅱ 302 to the other end. Head Ⅰ 210 and clamping head Ⅱ 220, the pressing part is included in the figure, and the pressing part is deleted, which is the clamping pliers. Since the clamping pliers clamping head directly protrudes from the rotating part of the cheek, the two clamping surfaces of the horizontal groove clamping surface The closer the head is to the axis of rotation, the easier it is to clamp;

Abstract

The invention relates to a pair of kirschner wire operating forceps, which comprise two cheek rotating parts which rotate relatively, each cheek rotating part extends to one end to form a forceps head, and the two forceps heads form an opening and closing forceps mouth; and each cheek rotating part extends towards the other end to form a handle. The forceps are characterized in that the forceps head can be two clamping heads which are provided with transverse groove clamping surfaces which are matched with each other. The forceps is simple in structure and solves the problems of clamping, bending and cutting of orthopedic kirschner wires.

Description

technical field [0001] The invention belongs to orthopedic surgical instruments, in particular to surgical forceps for clamping, bending and cutting orthopedic Kirschner wires. Background technique [0002] Kirschner wire is a commonly used internal fixation material in orthopedics. It is a slender cylindrical structure with a tip. Its specification is generally fixed at about 20 centimeters, and there are several specifications with a diameter of 0.5-3.5 millimeters. It is used to fix small fractures or avulsion fractures and other fractures with low stress. It is also often used in the fixation of temporary fracture blocks in orthopedic surgery. Although Kirschner wires provide a lot of convenience for fracture reduction and fixation, there are also many complications, mainly including two aspects: the sharp tail protrusions of the Kirschner wires irritate the surrounding soft tissue and the displacement of the Kirschner wires causes loosening. [0003] In order to solve ...
