Embodiment approach

[0086] Figure 11 A preferred exemplary embodiment of such a tool mount 20 according to the invention is shown, the components of which are described in detail below and with respect to its cooperation with the tool 1 described at the outset.

[0087] First of all, the tool mount or tool lock 20 of the invention and according to a preferred exemplary embodiment of the invention comprises a radially inner tool receiving tube (hereinafter referred to as lead shaft) 22 which Comprising: a longitudinally slotted (beak-shaped) distal torque transfer portion and locking portion 24 at its distal end; in its slotted torque transfer zone 24a (see Figure 6 ), said portion 24 has an outer diameter adapted to the large-diameter tool shaft portion 6a and, in its adjoining locking zone 24b, an inner diameter adapted to the small-diameter tool shaft portion 6b. In this arrangement, the longitudinal slot 26 forms a slot width into which the tool shaft 1 can be inserted into the region of th...

Abstract

A surgical torque-transferring instrument includes a preferably universal handpiece to which a handpiece shaft having an internal torsion rod or an internal tool shaft can be connected. The torsion rod can be connected to a torque transmission train or drive within the handpiece via a plug-type coupling which includes a male and female coupling piece which can be axially plugged into each other. The cross-sectional shape of the two coupling pieces approximately corresponds to a four-leaved cloverleaf.

Description

technical field [0001] The present invention relates to a surgical instrument for providing torque and a driven tool which is rotatably supported in an instrument handpiece or in a handpiece shaft connected to the instrument handpiece and which transmits the torque as high as possible to all Describe the driven tool. Background technique [0002] In advanced (minimally invasive) surgery, various instruments are used for fragment removal or material removal machining of e.g. Machining, the instrument includes an ergonomically shaped handpiece and optional replaceable tools (such as milling cutters, rotary knives, polishing heads, etc.) rotatably supported in the handpiece at a distance end so that it can be driven. Depending on the intended use and expected rotational speed, the tool drive is a hydraulic, pneumatic or electric drive that communicates with the The tools are operatively connected. The drive means can be integrated into the handpiece or realized as an extern...
