Patent ID: 8702740

Claim:
A medical punch with a hollow shaft, a tool point that is positioned on the distal end of the hollow shaft and comprises a rigid cutting part and a displaceable cutting part that can slide with respect to the rigid cutting part, and with a handle positioned on the proximal end of the hollow shaft, such that the displaceable cutting part and the handle are operatively connected with one another by a push/pull device that is displaceably mounted in the hollow shaft and an anti-tilt mechanism is positioned on the tool point to stabilize the cutting parts in their axially parallel alignment to one another, characterized in that the rigid cutting part comprises a sleeve-shaped proximal portion that encloses the displaceable cutting part and a distal punch portion that is configured as a single unit with the sleeve-shaped proximal portion, and in that the tool point comprises a sleeve-shaped enclosure that is slidable directly onto the sleeve-shaped proximal portion of the rigid cutting part for connecting the rigid cutting part and the displaceable cutting part to form a single assembly unit and wherein the single assembly unit is detachably connected with the hollow shaft by a coupling mechanism configured on the sleeve-shaped proximal portion, wherein the coupling mechanism is configured as a bayonet connection and wherein the anti-tilt mechanism is configured as the sleeve-shaped enclosure.
