Problems solved by technology

[0002] When reducing and internally fixing phalanx fractures in children, they often use electric drills for internal fixation with Kirschner wires as in internal fixation for adult phalanx fractures. However, due to the characteristics of small and soft bones in children and the fast speed of electric drills, it is difficult to control the force , it is easy to cause the displacement of the fracture block, or even the splitting of the fracture block, resulting in the failure of the operation, and the electric drill is faster and has high energy.

Abstract

The invention discloses a hand twisting Kirschner wire for the phalanges of children, and belongs to low-energy injury. The hand twisting Kirschner wire comprises a Kirschner wire, a conical head and a handle. The handle is in the shape of circular cake; one end of the Kirschner wire is fixedly connected with the handle, the axis of the Kirschner wire coincides with the axis of the handle, and the head is arranged at the other end of the Kirschner wire; scales are arranged on the Kirschner wire. Owing to the mode, the hand twisting Kirschner wire has the advantages that the hand twisting Kirschner wire is applicable to fracture fixation on the phalanges of the children, and insertion force, the insertion directions and the insertion depths are easy to control.

Description

technical field [0001] The invention relates to the field of internal fixation materials for children's phalanx fractures, in particular to a hand-twisted children's phalanx Kirschner wire. Background technique [0002] When reducing and internally fixing phalanx fractures in children, they often use electric drills for internal fixation with Kirschner wires as in internal fixation for adult phalanx fractures. However, due to the characteristics of small and soft bones in children and the fast speed of electric drills, it is difficult to control the force , It is easy to cause the displacement of the fracture block, or even the splitting of the fracture block, leading to the failure of the operation, and the electric drill speed is high, and the energy is high. For example, when the Kirschner wire needle reaches the epiphysis, it is easy to damage the epiphysis, which may cause bone development deformity. Contents of the invention [0003] The main technical problem to be ...
