1. A surgical system, comprising:
- a tool driver configured to releasably and replaceably engage with a surgical tool having an elongate shaft with an end effector at a distal end of the elongate shaft, the tool driver including a plurality of motors and a plurality drive disks each configured to be simultaneously driven by at least one of the motors and thereby cause a single motion of the end effector, wherein the single motion includes any one of closing jaws of the end effector, translating a cutting element along the end effector, and rotating the end effector relative to the elongate shaft.

Abstract
Various exemplary methods, systems, and devices for causing end effector motion with a robotic surgical system are provided. In general, a surgical tool can be configured to releasably and removably couple to a robotic surgical system. The robotic surgical system can include two motors configured to provide torque to the surgical tool to drive one single function of the surgical tool. In at least some embodiments, at least one of the two motors configured to cooperate with another motor to drive the single function of the surgical tool can be configured to drive a second function of the surgical tool.

7. A surgical system, comprising:
-
a surgical tool including an elongate shaft, an end effector at a distal end of the elongate shaft, and a plurality of actuation shafts operatively coupled to the end effector and extending along the elongate shaft, each of the actuation shafts being configured to operate a function of the end effector such that the end effector has a plurality of functions; and a tool driver configured to releasably and replaceably operatively engage the surgical tool, the tool driver including a plurality of motors and a plurality of drive disks, two of the drive disks being configured to be simultaneously driven by respective ones of the motors and thereby actuate one of the actuation shafts and cause one of the functions of the end effector. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A surgical method, comprising:
-
actuating a plurality of motors of a tool driver of a robotic surgical system and thereby simultaneously drive more than one of a plurality of drive disks of the tool driver, the driving of the more than one of the plurality of drive disks causing performance of a single function of an end effector of a surgical tool, the surgical tool including a proximal housing releasably and replaceably coupled to the tool driver, and the surgical tool including an elongate shaft extending distally from the proximal housing and having the end effector at a distal end thereof, wherein the single function of the end effector includes any one of closing jaws of the end effector, translating a cutting element along the end effector, rotating the end effector relative to the elongate shaft, and rotating the elongate shaft and the end effector relative to the proximal housing. - View Dependent Claims (16)
