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.
Claims17
A medical device drive system comprising:
- 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 being coupled to a movable element, wherein;
- the rotational input is configured to rotate in a first direction to cause the coupling member to engage with the engagement feature of the first gear and to rotate the coupling member, the first gear, and the second gear to move the movable element;
- and
- the rotational input is configured to rotate in a second direction without causing the coupling member to be engaged with the engagement feature and without moving the movable element.
A medical device drive system comprising:
- a first gear;
- a second gear coupled to a drive train that is configured to retract an instrument, the second gear coupled to the first gear;
- a manual input that is selectively engageable with the first gear,
- wherein the manual input is configured to rotate in only one direction to cause the manual input to engage with the first gear to rotate the first gear and the second gear to retract the instrument.
