Surgical instrument with an apparatus for limiting the transfer of a force
First Claim
1. Surgical instrument comprisinga movable actuation element;
- at least one working part moved by said actuation element,an apparatus for limiting a transfer of a force transferred via said actuation element to said at least one working part, said apparatus having at least one wedge surface associated to said actuation element, said wedge surface rising perpendicular to its movement when moving said actuation element;
a housing which can be spread apart by said wedge surface by movement thereof, thereby deforming said housing to a spread housing; and
an elastically spreadable ring circumferentially surrounding said housing in its spreading section, said elastically spreadable ring being spread by said housing when it is spread apart by said wedge surface, and said ring can close said spread housing when said wedge surface is moved out of its spreading engagement with said housing.

Abstract
An surgical instrument comprises a movable actuation element, at least one working part moved by said actuation element, an apparatus for limiting a transfer of a force transferred via said actuation element to said at least one working part. Said apparatus has at least one wedge surface associated to said actuation element, said wedge surface rising perpendicular to its movement when moving said actuation element. A housing is provided which can be spread apart by said wedge surface by movement thereof, and an elastically spreadable ring circumferentially surrounds said housing in its spreading section, said elastically spreadable ring can close said spread housing when said wedge surface is moved out of its spreading engagement with said housing.

24. Surgical instrument comprising:
-
a shaft extending along an axis; a movable actuation element axially displaceable along said shaft; at least one working part moved by said actuation element; an apparatus for limiting a transfer of a force transferred via said actuation element to said at least one working part, said apparatus having at least one wedge surface associated to said actuation element and extending in an axial direction, said wedge surface rising perpendicular to its movement when moving said actuation element; a housing which can be spread apart by said wedge surface by movement thereof, and an elastically spreadable ring circumferentially surrounding said housing in its spreading section, said elastically spreadable ring can close said housing when said wedge surface is moved out of its spreading engagement with said housing.
