Abstract
Surgical tool for use in guided surgery having a distal end portion having a functional element, a shank on the opposite end of the tool, and a substantially circular cylindrical guide portion. The guide portion is located between the functional element and the shank and has at least one visual marker. The at least one marker has at least one recess which is finite in the circumferential direction such that, at the axial location of the recess a section of guide portion having outer radius r is maintained.
Claims19
Surgical tool for use in guided surgery with a longitudinal axis comprising:
- a functional element at a distal end of the tool,
- a shank on the opposite end of the tool, and
- a cylindrical guide portion having an outer radius r which defines a guide surface for cooperation with a guide element, the guide portion being located on the longitudinal axis between the functional element and the shank and having a plurality of markers lying in different axial planes,
- each marker comprising a plurality of recesses located in the same axial plane and having the same distance to the distal end of the tool, forming a set, said recesses being finite in the circumferential direction and separated from each other by sections of the guide surface such that, at the axial location of the marker, sections of the guide surface are maintained,
- wherein the plurality of recesses in each marker are positioned in such a way that at least one recess is visible from any viewing angle about the longitudinal axis.
Kit comprising a surgical tool and a guide element, the surgical tool comprising
- a longitudinal axis,
- a functional element at a distal end of the tool,
- a shank on the opposite end of the tool, and
- a cylindrical guide portion having an outer radius r which defines a guide surface for cooperation with the guide element, the guide portion being located on the longitudinal axis between the functional element and the shank and having at least one marker,
- the at least one marker comprising a plurality of recesses, said plurality of recesses being finite in the circumferential direction such that, at the axial location of the recess, a section of the guide surface is maintained,
- wherein the plurality of recesses in each marker are positioned in such a way that at least one recess is visible from any viewing angle about the longitudinal axis.
