Patent
Method for passively decoupling torque applied by a remote actuator into an independently rotating member
TL;DR: In this article, a rotary mechanism is coupled with a rotatable main shaft via a transmission and a rotational coupling so that the main shaft is passively subjected to a counteracting torque opposite in direction to the actuation torque transmitted to the rotary mechanisms.
Patent
Surgical instrument with single drive input for two end effector mechanisms
TL;DR: In this article, a surgical assembly is described in which consists of an end effector, a base supporting the end-effector, an input link movable relative to the base through a range of motion between a first configuration and a second configuration, and an actuation mechanism.
Patent
Grip force control in a robotic surgical instrument
TL;DR: In this article, a surgical assembly includes an end effector including a jaw operable to grip a patient tissue and a spring assembly, which is preloaded to inhibit relative movement between the input link and the output link.
Patent
Surgical Instrument with Shiftable Transmission
TL;DR: In this paper, a surgical tool with an elongated shaft having a proximal end and distal end is described, where an effector body includes a plurality of motor interfaces for driving the plurality of effector mechanisms.

TL;DR: In this paper, a system and method of variable velocity control of a surgical instrument in a computer-assisted medical device is described, which includes an end effector located at a distal end of the instrument, an actuator, and one or more drive mechanisms for coupling force or torque from the actuator to the end-effector.
