Detailed ways

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

A kind of Kirschner wire handle as shown in Figure 1 to 2, comprises handle 1, and the center of handle 1 is provided with circular hole 2; The opposite side of the clamping rod 9 is provided with a clamping rod 9, the clamping rod 9 is hinged to the handle 1 at one end away from the round hole 2, and the lower side of the hinged end of the clamping rod 9 is fixedly connected to the opening and closing operating rod 11; when the opening and closing operating rod 11 is opened upwards, The Kirschner wire is inserted into the round hole 2, and then the opening and closing operating rod 11 is closed downward, and the end face of the arc-shaped baffle plate 3 and the clamping rod 9 tightly clamps the needle rod 4 of the Kirschner wire to limit the sliding of the Kirschner wire.

The arc-shaped baffle 3 is fixedly installed on the lower end surface of the handle 1, and the arc-shaped baffle 3 is used to limit the movement of the Kirschner wire.

The handle 1 is provided with a hinged seat 10 on the side of the clamping rod 9 away from the round hole 2, the hinged seat 10 is hinged to the clamping rod 9 through the hinged shaft 8, and the hinged shaft 8 is made of stainless steel, firm and smooth.

The clamping rod 9 is vertically connected with the opening and closing operation rod 11, and is in an "L" shape. By pushing the opening and closing operation rod 11 up and down, the clamping rod 9 can be opened and closed, and then the Kirschner wire can be clamped and released.

The outer side of the opening and closing operating rod 11 is nested and connected with a rubber sleeve 12 , and the rubber sleeve 12 can increase the operating comfort of the opening and closing operating rod 11 .

When working: firstly, the handle and the Kirschner wire will be fully sterilized; open the opening and closing operating lever 11 downwards, then pass the Kirschner wire through the round hole 2 of the handle 1, then turn upwards to close the opening and closing operating lever 11, and finally The ends of the arc-shaped baffle 3 and the clamping rod 9 tightly clamp the needle rod 4 of the Kirschner wire to fix the Kirschner wire. At this point, the handle can be hammered to place the K-wire into the bone. For soft bones such as vertebral bodies, the Kirschner wire can be inserted into the bone only by holding the handle with the hand. When the fracture is healed, this handle can be installed to facilitate the removal of the Kirschner wire.
