Abstract
A medical device such as a surgical forceps is usable with at least two different jaw forces. The device can include a longitudinal shaft, having a proximal portion and a distal portion. An end effector can be attached to and can extend from the distal portion. A compressible member can be aligned with the longitudinal shaft. The compressible member can be configured for applying a variable maximum bias force for communication to the end effector. An end-user-positionable seat can be located against a first end of the compressible member. The seat can be actuatable by the end-user for varying the variable maximum bias force.
Claims20
A medical device comprising:
- a longitudinal shaft, having a proximal portion and a distal portion, with an end effector attached to and extending from the distal portion;
- a compressible member, aligned with the longitudinal shaft, the compressible member configured for applying a variable maximum bias force for communication to the end effector;
- and
- an end-user-positionable seat, located against a first end of the compressible member, the seat actuatable by an end-user for varying the variable maximum bias force.
A medical device comprising:
- a longitudinal shaft, having a proximal portion and a distal portion, with an end effector attached to and extending from the distal portion;
- a handpiece, operably connected to the end effector, the handpiece attached to and extending from the proximal portion of the longitudinal shaft;
- and
- a variable motion transfer assembly actuatable for adjusting force effected by the end effector.
A computer-implemented method comprising:
- receiving user input to apply a first force to a target with a forceps with the forceps in a first mode of operation;
- and
- switching the forceps from the first mode of operation to a second mode of operation at a user-specified maximum force level established by a user moving a user-positionable seat to compress a compressible member within the forceps such that the forceps are actuatable for applying a second force greater than the first force.
