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.
Claims18
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 coupled to a movable element;
- the system having a first system state and a second system state, wherein 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, and 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,
- wherein the coupling member is slidably coupled to the rotational input, the coupling member sliding away from the rotational input as the rotational input is turned in a first direction.
A medical device drive system comprising:
- a first gear;
- a second gear coupled to a drive train that configured to retract an instrument, the second gear coupled to the first gear;
- a coupling member;
- and
- a manual input that is selectively engageable with the first gear by the coupling member,
- wherein in a first state the manual input is not engaged with the first gear, actuation of the manual input does not turn the first gear and does not retract the instrument, and actuation of the manual input advances the coupling member toward the first gear until the coupling member engages the first gear, and in a second state the manual input is engaged with the first gear, and actuation of the manual input turns the first gear and the second gear to retract the instrument.
A medical device drive system comprising:
- a means for driving a manual input against a coupling member;
- a means for engaging the coupling member with a first gear;
- a means for retracting an instrument, the means for retracting the instrument coupled to the first gear:
- and
- means for locking the coupling member with the first gear,
- wherein in a first state the coupling member is not engaged with the first gear and actuating the manual input moves the coupling member toward the first gear but does not drive the first gear, and in a second state the coupling member is engaged with the first gear and actuating the manual input drives the first gear and retracts the instrument.
