Problems solved by technology

[0004] However, manually clamping the Kirschner wires often cannot accurately grasp the clamping force of the Kirschner wires. Too tight or over-feeding clamping forces will affect the surgical effect of bone tissue surgery, and manual clamping Tight Kirschner wires also cannot guarantee a constant clamping force while drilling
Since the Kirschner wire rotates at high speed when drilling, any instantaneous change in clamping force will exert an instantaneous lateral moment on the high-speed rotating Kirschner wire, and this lateral moment, even if it is small, will affect the high-speed rotating Kirschner wire. Negative impact of needles, even lead to breakage of Kirschner wires
In addition, it is also challenging to realize the automatic clamping of the Kirschner wire in the small internal space of the Kirschner wire holding device

Abstract

The present invention discloses a Kirschner wire clamping device. The Kirschner wire clamping device comprises an outer shell, and a motor, a gear set and a clamping head mechanism arranged in the outer shell, the gear set is connected with a driving shaft of the motor, and the clamping head mechanism comprises a first sleeve, a second sleeve and a nut; the first sleeve is connected with the gearset and also provided with a front end and a rear end; the second sleeve is sleeved in the first sleeve and matched with a conical surface of the first sleeve, besides, the second sleeve is provided with a first end and a second end, Kirschner wire penetrates through the second sleeve and extends through the first end of the second sleeve and out of the front end of the first sleeve, and the second end of the second sleeve extends out of the rear end of the first sleeve; and the nut is arranged at the rear end of the first sleeve and detachable from the first sleeve, and besides, the second end of the second sleeve is screwed into the nut. A Kirschner wire drilling device is provided with the Kirschner wire clamping device and a pushing device, and the pushing device is connected with theKirschner wire clamping device to apply pushing force to the Kirschner wire clamping device.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a Kirschner wire clamping device and a Kirschner wire drilling device with the Kirschner wire clamping device. Background technique [0002] In bone tissue surgery, it is often necessary to use Kirschner for positioning and other operations on bone tissue. Kirschner wires are small in diameter and long in length, generally no more than 4mm in diameter, and more than 200mm in length, so the Kirschner wires need to be clamped on the electric drilling device through a special clamping device. When drilling, the Kirschner wire extends out of the front end of the clamping device for a certain length. After drilling into a certain depth, loosen the clamping device so that more lengths of the Kirschner wire extend out of the front end of the clamping device, and then re-clamp the Kirschner wire , and then drill a certain depth, and so on, until the Kirschner wire drills to ...
