Method and apparatus for mounting a sheath onto the distal end of a surgical shaft instrument
First Claim
1. An apparatus for mounting a sheath onto a distal end of a surgical shaft instrument, the apparatus comprising:
- a base body;
at least two spreading elements each having a proximal end and a distal end for fastening a sheath on the base body, the proximal ends of the at least two spreading elements being mounted to the base body such that the at least two spreading elements extend from the proximal ends into the base body, the at least two spreading elements being actuatable to radially widen at least a proximal end of the sheath; and
an insertion opening formed in the base body between the proximal ends of the at least two spreading elements, the insertion opening providing an entry point to receive a distal end of a surgical shaft instrument and direct the distal end of the surgical shaft instrument into the widened proximal end of the sheath;
the spreading elements being configured for transferring the sheath from the base body onto the distal end of the surgical shaft instrument.

Abstract
A method for mounting a sheath onto the distal end of a surgical shaft instrument, in particular the tool tip of a dilation instrument. The method makes handling easy and allows the sheath to be fastened on the instrument in a rapid manner sparing of material, characterized by these steps: a) fastening the sheath on an apparatus for mounting a sheath onto the distal end of a surgical shaft instrument; b) radially widening at least the proximal end of the sheath and inserting the distal end of the surgical shaft instrument into the widened sheath c) transferring the sheath from the apparatus to the distal end of the surgical shaft instrument; and d) removing the distal end of the surgical shaft instrument from the apparatus. The invention also relates to an apparatus to perform this method.
