Abstract
A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.
Claims20
A surgical instrument, comprising:
- a surgical tool;
- a gear operably coupled to the surgical tool;
- a manual input member;
- and
- a coupling member positioned between the manual input member and the gear;
- wherein on a condition that the coupling member is in a first position, the manual input member is operably coupled to drive rotation of the gear;
- and
- wherein on a condition that the coupling member is in a second position, the manual input member is operably decoupled from the gear.
A surgical instrument, comprising:
- a surgical tool;
- a gear operably coupled to the surgical tool;
- a manual input member;
- and
- a coupling member positioned between the manual input member and the gear;
- wherein the coupling member moves longitudinally between a first position and a second position in response to a rotation of the manual input member;
- wherein the first position is distal to the second position;
- wherein on a condition that the coupling member is in the first position, the manual input member is operably coupled to drive rotation of the gear;
- and
- wherein on a condition that the coupling member is in the second position, the manual input member is operably decoupled from the gear.
