Abstract
A surgical bone milling tool, in particular for the arthrodesis of a, preferably the first, metatarsophalangeal joint, with a rotatable milling cutter holder and at least one milling cutter for the production of a concave or convex milling contour in the bone, which is able to be fixed detachably on the milling cutter holder by a fixing element. Provision is made that the fixing element comprises a detent having a spring element provided for the detachable engagement of the milling cutter on the milling cutter holder.
Claims19
A surgical bone milling tool for the arthrodesis of a metatarsophalangeal joint comprising:
- a rotatable milling cutter holder, the milling cutter holder operable to rotate relative to a bone of the metatarsophalangeal joint during a bone milling procedure;
- and
- at least one milling cutter for the production of a concave or convex milling contour in a bone;
- wherein the milling cutter is removably fixed on the milling cutter holder by a fixing element that provides for detachable engagement of the milling cutter on the milling cutter holder, the fixing element comprising a spring element that extends peripherally around and engages at least a portion of an outer surface of the milling cutter holder, and wherein in an attached state the milling cutter and the milling cutter holder are rotationally fixedly coupled together, such that the milling cutter is incapable of rotating relative to the milling cutter holder, to allow simultaneous rotation of the milling cutter with the milling cutter holder.

- a rotatable milling cutter holder, the milling cutter holder operable to rotate relative to a bone of the metatarsophalangeal joint during a bone milling procedure;
- and
- at least one milling cutter for the production of a concave or convex milling contour in a bone;
- wherein the milling cutter is removably fixed on the milling cutter holder by a fixing element that provides for detachable engagement of the milling cutter on the milling cutter holder, the fixing element comprising a spring element, and wherein in an attached state the milling cutter and the milling cutter holder are rotationally fixedly coupled together to allow simultaneous rotation of the milling cutter with the milling cutter holder;
- and
- wherein the spring element extends peripherally around and engages at least a portion of an outer surface of the milling cutter holder.
