A method for repairing a bone of a patient may include superimposing a first virtual boundary on a virtual bone and superimposing a second virtual boundary on the virtual bone. The method may further include robotically modifying the bone of the patient with a planar tool along a first working boundary to create a first surface. The first working boundary may correspond to the first virtual boundary. The method may further include robotically modifying the bone of the patient with a rotary tool along a second working boundary to create a second surface. The second working boundary may correspond to the second virtual boundary.

A system includes a robotic manipulator comprising an arm and an end effector coupled to the arm and being moveable by the arm for interacting with a target site in a manual mode and an autonomous mode of operation. A navigation system is configured to track a position of the end effector and the target site. One or more controllers are configured to define a first virtual boundary relative to the target site, prevent the end effector from penetrating the first virtual boundary in the manual mode, and allow the end effector to penetrate the first virtual boundary in the autonomous mode.

A treatment tool includes an long member; a treatment portion rotatable about a longitudinal axis of the long member; a twisting wire one end of which is connected to the treatment portion, the other end extending toward a proximal end side of the long member; an operating portion, at the proximal end side, that includes a body fixed to the long member, and an operating member configured to rotate around and move along the axis; and a mechanism configured to couple the operating member with the wire and convert a rotation of the operating member into traction of the wire. The body includes a portion configured to come into contact with the operating member to prevent the rotation in a case where the operating member is urged in a direction toward a distal end side of the long member together with the mechanism by a restoring force of the wire.

A tool assembly for use with a closure actuator that is configured to move a first axial closure distance upon actuation thereof. A surgical end effector is operably coupled to a shaft assembly. A firing member assembly operably interfaces with an articulation member. A closure system operably interfaces with the closure actuator such that when the closure actuator is axially advanced through the first axial closure distance, the closure system disengages the firing member assembly and the articulation member and also moves a closure member axially through a second axial closure distance that is less than the first axial closure distance to apply closure motions to the end effector.

A tool includes a transmission mechanism, a shaft rotatable relative to the transmission mechanism, and a stop mechanism associated with the shaft, the stop mechanism being transitionable between a first state and a second state. In the first state, the shaft is free to rotate in a first direction and in a second direction opposite to the first direction. In the second state, the shaft is constrained from rotating in one of the first direction or the second direction by a defined first endpoint of a range of rotational motion of the shaft. Devices and methods relate to rotation stop mechanisms.

A method to guide in preparation of a bone relies on an instrument having a shaft with a working end and a stop member. The shaft is free to translate along an axis. Surgical planning data is registered to the bone to determine intra-operative coordinates of the desired axis and depth. The instrument holder is positioned by the bone so the stop member contacts the instrument holder to prevent translating beyond the desired depth. Alternatively, an arm is manipulated to align the instrument with the desired axis. The working end rests on the bone to define a linear separation to the desired depth. By proximally translating the instrument holder to contact the stop member and distally translating the instrument holder along the shaft, the stop member physically stops translating beyond the desired depth. A surgical system for performing the methods is provided; a reamer or impactor are also disclosed.

The present disclosure is directed to augmented reality navigation systems and methods of their use that, inter alia, address the need for systems and methods of robotic surgical system navigation with reduced distraction to surgeons. Augmented reality navigation systems disclosed herein enable a surgeon to maintain focus on a surgical site and/or surgical tool being used in a surgical procedure while obtaining a wide range of navigational information relevant to the procedure. Navigational information can appear in the augmented reality navigation system as being presented on virtual displays that sit in a natural field of view of a surgeon during a procedure. Navigational information can also appear to be overlaid over a patient's anatomy. Augmented reality navigation systems comprise a head mounted display comprising an at least partially transparent display screen, at least one detector connected to the head mounted display for identifying real-world features, and a computer subsystem.

A surgical tool is disclosed. The surgical tool has a tool mounting portion having a tool mounting housing, a tool mounting plate, and a coupler to couple a shaft assembly having an articulation section to the tool mounting portion. An articulation mechanism is located within the tool mounting portion and is configured to receive a proximal end of the shaft assembly to articulate the articulation section of the shaft assembly. The articulation mechanism has a cam mechanism operative to articulate the articulation section of the shaft assembly. An interface mechanically and electrically couples the tool mounting portion to a manipulator.

A unitary base for a torque limiting device is disclosed. The base accepting a plurality of swappable torque limiting fixtures (STLF), whereby a single unitary disposable plastic base may be utilized to form a variety of different specific torque limiting devices and a method to construct and configure such a device.

A surgical instrument assembly comprising an end effector, a shaft assembly, a closure drive system, and a firing drive system is disclosed. The surgical instrument assembly further comprises a dual lock configured to engage a closure member and a firing member to prevent the firing member from being advanced distally from a proximal firing stroke position before the closure member is in a distal closure stroke position. The dual lock is further configured to prevent the closure member from being retracted from the distal closure stroke position before the firing member is returned to the proximal firing stroke position after the firing stroke.
