Abstract
A handle of a medical device may comprise an actuator; a lock movable relative to the actuator and having a feature movable relative to the actuator; and a rack having plurality of teeth separated from one another by a plurality of gaps. The lock may be configured to move the feature from (a) a first configuration, in which the feature is disposed in the gap, between two of the plurality of teeth, such that the two teeth inhibit the actuator from rotating; to (b) a second configuration, in which the feature is disposed outside of the gap, such that the actuator is rotatable. In the second configuration, the teeth may be disposed between the feature and the actuator.
Claims21
1-20. (canceled)
A handle of a medical device, the handle comprising:
- a handle housing having a stationary rack gear including a plurality of teeth separated from one another by a plurality of gaps;
- and
- a locking mechanism having a button and a peg;
- wherein the locking mechanism is configured to move the peg radially relative to the stationary rack gear from (a) a first configuration, in which the peg is disposed in a first gap of the plurality of gaps, the first gap being between two teeth of the plurality of teeth, such that the two teeth inhibit the locking mechanism from rotating;
- to (b) a second configuration, in which the peg is disposed entirely radially inward of the two teeth of the plurality of teeth, such that the locking mechanism is rotatable relative to the rack gear, wherein, in the second configuration, the two teeth are disposed radially between the peg and the button.
A handle of a medical device, the handle comprising:
- a handle body having a stationary rack gear disposed thereon, wherein the stationary rack gear includes a plurality of teeth;
- and
- a locking mechanism comprised of a button, a peg, and a body, wherein the body is comprised of a plurality of segments arranged to conform to a surface of the handle body,
- wherein the stationary rack gear is disposed between the peg and the button, and wherein the button is configured to move the peg radially relative to the stationary rack gear.
A method of operating a medical device, the method comprising:
- with an actuator in a first position, depressing a button of a locking mechanism of the actuator radially inward, thereby moving a peg radially inward relative to (1) a body of the locking mechanism and (2) a plurality of teeth disposed on a surface of handle;
- while depressing the button, rotating the actuator to a second position;
- and
- with the actuator in the second position, releasing the button, thereby moving the peg radially outward relative to (a) the body of the locking mechanism and (b) the plurality of teeth so that the plurality of teeth inhibit rotation of the peg.
