Abstract
A medical device includes an end effector at a distal end of the medical device, an actuator coupled to a proximal end of the end effector, a pivot arm pivotally coupled to the end effector distal of the proximal end of the end effector, where actuation of the actuator pivots the end effector relative to the pivot arm, and a lock on the end effector and the pivot arm, where the lock has a first state permitting the end effector to pivot relative to the pivot arm and a second state restricting the end effector from pivoting relative to the pivot arm.
Claims14
A medical device, comprising:
- an end effector at a distal end of the medical device;
- an actuator coupled to a proximal end of the end effector;
- a pivot arm pivotally coupled to the end effector distal of the proximal end of the end effector, wherein the pivot arm includes:
- a first opening at a proximal end of the pivot arm;
- a second opening in a sidewall of the pivot arm;
- and
- a lumen extending from the first opening to the second opening;
- wherein the actuator is configured to extend through each of the first opening, the lumen, and the second opening, and wherein actuation of the actuator pivots the end effector relative to the pivot arm;
- and
- a lock on the end effector and the pivot arm, wherein the lock has a first state permitting the end effector to pivot relative to the pivot arm and a second state restricting the end effector from pivoting relative to the pivot arm.
