Abstract
A system includes a manipulator arm and a cannula mount arm. The manipulator arm includes a link and a locking assembly coupled to the link. The cannula mount arm includes a latch. The cannula mount arm is configured to be extended from the link to an extended position. The locking assembly is configured to engage with the latch when the cannula mount arm is extended from the link to the extended position so as to lock the cannula mount arm in the extended position. Activation of an electrical component coupled to the locking assembly is inhibited when a cannula is docked to the cannula mount arm.
Claims20
A system comprising:
- a manipulator arm comprising a first link and a latch link coupled to the first link and configured to engage with a latch;
- and
- a cannula mount arm comprising the latch;
- wherein:
- the cannula mount arm is configured to be manually extended from the first link to an extended position, wherein extending the cannula mount arm stores potential energy in a spring;
- the latch link is configured to engage with the latch when the cannula mount arm is extended from the first link to the extended position so as to lock the cannula mount arm in the extended position;
- and
- disengagement of the latch link from the latch results in the cannula mount arm being retracted into the first link using the potential energy stored in the spring.
A cannula mount system comprising:
- a cannula dock configured to receive a cannula;
- a cannula mount arm;
- and
- a latch;
- wherein:
- the cannula mount arm is configured to be manually extended from a first link of a manipulator arm to an extended position, wherein extending the cannula mount arm stores potential energy in a spring;
- the latch is configured to engage with a latch link of the manipulator arm when the cannula mount arm is extended from the first link to the extended position so as to lock the cannula mount arm in the extended position;
- and
- disengagement of the latch link from the latch results in the cannula mount arm being retracted into the first link using the potential energy stored in the spring.
