Fixing fixture for processing K-wire

Abstract

A K-wire needs to process a crumb dividing slot to remove bone crumbs, which helps to lower the temperature. At present, most of clamps holding the K-wire cannot process the crumb dividing slot, and in response to the main problem, the fixing fixture for processing the K-wire mainly comprises an indexing plate, a rocker, a rotary indexer, a nut support seat, a nut, a spring collet, a left adjustment screw, a right adjustment screw, a pitch dial, a left bracket, a right bracket, a pitch bottom plate and a bottom plate; a horizontal rotary table mainly includes a base, a dial, a motor and a motor nut; according to the working principle of the fixing fixture for processing the K-wire, the horizontal rotation of the K-wire is controlled by the horizontal rotary table, and the vertical pitch movement and the rotation around the axis of the K-wire are controlled by the tiltable rotary table in order to achieve the purpose of grinding a bevel at the end of the K-wire and processing the various shapes of the crumb dividing slots at the tip.

Description

technical field [0001] The invention belongs to the technical field of medical tool processing, and in particular relates to a fixed fixture for Kirschner wire processing. Background technique [0002] During the bone drilling process with the Kirschner wire, powdery bone debris will be produced, which is difficult to discharge and may easily cause an increase in the drilling temperature. At present, most of the Kirschner wires used do not have chip dividing grooves, and the high temperature generated during the drilling process will damage the bone cells. Aiming at this main problem, the present invention designs a new type of fixed fixture for Kirschner wire processing, which is used to grind the bevel at the end of the Kirschner wire and process various shapes of chip dividing grooves at the tip, so as to realize timely discharge of bone chips , The purpose of reducing the bone drilling temperature. Contents of the invention [0003] The invention designs a fixed fixt...
