Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a quantitative bending tool for Kirschner wires. Background Art

[0002] In orthopedic surgery, Kirschner wires are often used as steel wires for fixing broken bones. Generally, Kirschner wires are about 20 centimeters long and have a diameter of 0.5 to 3 mm. They have several different specifications and are used to fix short fractures or avulsion fractures with low stress. They are also often used to fix temporary fracture fragments in orthopedic surgery. At present, ordinary pliers are generally used to force Kirschner wires to be bent in clinical practice. When using pliers to force bending, one plier is generally used to fix the Kirschner wire, and then another plier is used to bend the Kirschner wire. During the operation, two people are often required to cooperate to bend the pliers, which is time-consuming and laborious.

[0003] In order to facilitate the bending of Kirschner wires, we propose a Kirschner wire quantitative bending tool. Utility Model Content
