Abstract
A surgical instrument system is disclosed comprising a plurality of outputs driven by an input. The input is selectively engaged with the outputs by a shifting system.
Claims22
A surgical instrument, comprising:
- a handle comprising a first electric motor and a second electric motor;
- a shaft assembly attached to said handle, wherein said shaft assembly comprises:
- a rotatable input shaft operably coupled to said first electric motor;
- a rotatable shifting shaft operably coupled to said second electric motor;
- a first rotatable drive shaft;
- and
- a second rotatable drive shaft;
- and
- an end effector extending from said shaft assembly, wherein said end effector is configured to perform a first end effector function in response to the rotation of said first rotatable drive shaft, wherein said end effector is configured to perform a second end effector function in response to the rotation of said second rotatable drive shaft, wherein said rotatable shifting shaft is rotatable between a first position and a second position, wherein said rotatable input shaft is operably coupled to said first rotatable drive shaft when said rotatable shifting shaft is in said first position, and wherein said rotatable input shaft is operably coupled to said second rotatable drive shaft when said rotatable shifting shaft is in said second position.
6 more elements
A surgical assembly, comprising:
- a housing comprising a first electric motor and a second electric motor;
- a shaft assembly attached to said housing, wherein said shaft assembly comprises:
- a rotatable input shaft operably coupled to said first electric motor;
- a rotatable shifting shaft operably coupled to said second electric motor;
- a first rotatable drive shaft;
- and
- a second rotatable drive shaft;
- and
- an end effector extending from said shaft assembly, wherein said end effector is configured to perform a first end effector function in response to the rotation of said first rotatable drive shaft, wherein said end effector is configured to perform a second end effector function in response to the rotation of said second rotatable drive shaft, wherein said rotatable shifting shaft is rotatable between a first position and a second position, wherein said rotatable input shaft is operably coupled to said first rotatable drive shaft when said rotatable shifting shaft is in said first position, and wherein said rotatable input shaft is operably coupled to said second rotatable drive shaft when said rotatable shifting shaft is in said second position.
6 more elements
A surgical instrument, comprising:
- a handle comprising a first electric motor and a second electric motor;
- a shaft assembly operably attached to said handle, wherein said shaft assembly comprises:
- a rotatable input shaft operably coupled to said first electric motor;
- a rotatable shifting shaft operably coupled to said second electric motor;
- a first rotatable drive shaft;
- and
- a second rotatable drive shaft;
- and
- an end effector extending from said shaft assembly, wherein said end effector is configured to perform a first end effector function in response to the rotation of said first rotatable drive shaft, wherein said end effector is configured to perform a second end effector function in response to the rotation of said second rotatable drive shaft, wherein said rotatable shifting shaft is rotatable between a first engaged orientation and a second engaged orientation, wherein said rotatable input shaft is operably coupled to said first rotatable drive shaft when said rotatable shifting shaft is in said first engaged orientation, wherein said rotatable input shaft is operably coupled to said second rotatable drive shaft when said rotatable shifting shaft is in said second engaged orientation, wherein said rotatable input shaft is not operably engaged with said first engaged rotatable drive shaft when said rotatable shifting shaft is not in said first orientation, and wherein said rotatable input shaft is not operably engaged with said second rotatable drive shaft when said rotatable shifting shaft is not in said second engaged orientation.
