An end effector is removably connected to a robot arm under sterile conditions with an arm mount module configured to be permanently connected to the robot arm, and an arm drape module configured to be removably connected to the arm mount module by a first locking mechanism. A third module, which is a passive end effector, may be configured to be removably connected to the arm drape module by a second locking mechanism. In some embodiments, a sterile hand drape module is configured to be removably connected to the arm drape module by the second locking mechanism; and a hand mount module is configured to be removably connected to the hand drape module by a third locking mechanism, and to be permanently connected to the end effector or the hand mount module is the end effector itself.
The systems for connecting an end effector to a robot arm provide a signal or energy transmission pathway between the robot arm and the end effector. The transmitted energy can be electrical or mechanical.

A tool changer device for a robotic arm comprising a robot adapter (1) particularly adapted to be connected to a robotic arm (5) and to a tool (6). The robot adapter (1) comprises a pneumatic cylinder (117) inside which a piston (116) is slidably arranged for activating a coupling and uncoupling mechanism (120) of the robotic arm (5) to the tool (6). On one of the walls of the robot adapter (1) at least four through conduits (24, 25, 26, 27) are arranged, one end of which opens into the pneumatic cylinder (117) and another end of which opens outside of the pneumatic cylinder (117). The device further comprises a first differential pressure sensor (18) connected to at least two of the through conduits (24, 25), and a second differential pressure sensor (19) connected to another two of the through conduits (26, 27).

Generally, a sterile adapter for use in robotic surgery may include a frame configured to be interposed between a tool driver and a surgical tool, a plate assembly coupled to the frame, and at least one rotatable coupler supported by the plate assembly and configured to communicate torque from an output drive of the tool driver to an input drive of the surgical tool.

Techniques are described for testing whether an end effector, or component thereof, is correctly or incorrectly installed to a manipulation system. In an example, a manipulation system can include a manipulator arm configured to receive an end effector having a first moveable jaw, a transducer configured to provide first effort information of the end effector as the end effector moves, and a processor configured to provide a command signal to effect a first test move of the first moveable jaw, and to provide an installation status of the of the end effector using the first effort information of the first test move.

Generally, a system for use in a robotic surgical system may be used to determine an attachment state between a tool driver, sterile adapter, and surgical tool of the system. The system may include sensors used to generate attachment data corresponding to the attachment state. The attachment state may be used to control operation of the tool driver and surgical tool. In some variations, one or more of the attachment states may be visually output to an operator using one or more of the tool driver, sterile adapter, and surgical tool. In some variations, the tool driver and surgical tool may include electronic communication devices configured to be in close proximity when the surgical tool is attached to the sterile adapter and tool driver.

A robot comprises a mobile base, a robotic arm operatively coupled to the mobile base, and at least one interface configured to enable selective coupling to at least one accessory. The at least one interface comprises an electrical interface configured to transmit power and/or data between the robot and the at least one accessory, and a mechanical interface configured to enable physical coupling between the robot and the at least one accessory.

A quick change end effector system for use with a robot includes: a quick change end effector configured for application to a task to be completed by a robot, the quick change end effector further comprising an end effector magnet; and a robotic manipulator configured to lock to the end effector, the robotic manipulator further configured to use the end effector to complete the task, the robotic manipulator comprising a manipulator magnet, the manipulator magnet being configured to magnetically attract the end effector magnet, thereby locking the manipulator in a mechanically strong connection to the quick change end effector, wherein upon disengagement of the magnetic attraction locking the manipulator to the quick change end effector, the quick change end effector can be quickly removed from the manipulator.

A tool changer set out having a master unit and a tool unit. The master unit comprises a safety controller with two separate processing circuitries, a coupler and at least two coupling sensors. The tool unit comprises at least one tool unit sensor, the at least one tool unit sensor provides two output signals sent to the safety controller. The at least two coupling sensors individually detect if the tool unit is coupled to the master unit and the output signals are sent to the safety controller. The two separate processing circuitries are arranged to receive a request to decouple the tool unit, determine whether the tool unit is coupled to the master unit and whether the tool unit is in the tool stand, send the result of the determinations to other processing circuitry, receive a result of determinations and send a decouple signal.
