Patent ID: 10835320

Abstract:
A surgical system comprises an instrument and a teleoperated instrument operation system. The instrument comprises a drive member having an end effector coupled to the distal end and a ratchet assembly coupled to the proximal end. The ratchet assembly includes a pin, a gear, and a spring- loaded button. A lever is coupled to and configured to pivot relative to the ratchet assembly to engage the spring-loaded button to disengage the pin from the gear. The lever in a first position places the ratchet assembly in a gripping position in which the end effector grips a surgical accessory. The lever in a second position places the ratchet assembly in a release position in which the end effector releases the surgical accessory. The lever is movable while compressing the spring-loaded button. The teleoperated instrument operation system comprises a capture mechanism configured to move the lever between the first and second positions.
