A method for removing an implant attached to a bone during revision joint replacement surgery includes a library of implant models. A series of surface points are collected on the implant with a digitizer. A best match is computed between the collected surface points and an implant model in the library of implant models to register the position of the implant model to the implant. A location is computed of a material-implant interface based on the geometry of the implant model and the registered position of the implant model. Material is removed at the material-implant interface to separate the implant from the bone. A computer-assisted surgical system is provided for performing the method.

Systems and methods for stapling tissue, a vessel, duct, etc., during a surgical procedure are provided. The surgical stapling systems generally include a circular stapling tool with a shaft extending therefrom that has an end effector at a distal end thereof. The end effector can have a staple deck and an anvil. The circular stapling tool can be configured to drive at least two circular rows of staples through tissue engaged between the staple deck and the anvil to thereby staple the tissue, and the tool can be configured to drive a knife through tissue engaged between the staple deck and the anvil to thereby cut the tissue. The surgical stapling system can also include a control system that is configured to communicate with the circular stapling tool.

A shaft for a dental screwdriver configured to be inserted into a bore cavity of a dental prosthetic. The shaft has a drive tip for driving a dental screw used to fix the dental prosthetic to the dental implant when the shaft is inserted into the bore cavity of the dental prosthetic. The drive tip is made of a shape memory smart alloy. The shaft also has an axial shaft portion made of a shape memory smart alloy with different material characteristics than the shape memory smart alloy of the drive tip. The axial shaft portion is configured to elastically bend from an original shape to a bent shape along the axial shaft portion without imparting a bending action and torqueing forces along the drive tip when the dental screwdriver is inserted into the bore cavity of the dental prosthetic.

The surgical stapling system can also include a control system that is configured to communicate with the circular stapling tool.

Systems and methods for stapling tissue during surgery are provided. In one exemplary embodiment, a surgical stapling system is provided that includes a staple shaft assembly having a staple advancing and forming assembly and a shaft with a plurality of staples, a drive system operably coupled to the staple shaft assembly and operably coupled to at least one motor, and a control system. The drive system can have a plurality of stages of operation that drive the staple advancing and forming assembly to form a staple around tissue. The control system can be configured to actuate the at least one motor to drive the drive system and thereby control movement of the staple advancing and forming assembly and to modify a force applied to the drive system by the at least one motor during at least one stage of operation based on at least one predetermined threshold.

A computer-implemented method for collecting data within a facility is disclosed. The method includes receiving, by a computer system, perioperative data from a plurality of surgical devices located within the facility, the perioperative data associated with a plurality of surgical procedures performed in the facility; determining, by the computer system, procedural context data associated with the plurality of surgical procedures based at least in part on the perioperative data; aggregating, by the computer system, the perioperative data according to the procedural context data; and determining, by the computer system, trends associated with the surgical procedures performed in the facility according to the perioperative data and the procedural context data.

Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

A surgical hub is disclosed. The surgical hub includes a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to receive first image data from a first image sensor, the first image data represents a first field of view, receive second image data from a second image sensor, wherein the second image data represents a second field of view, and display, on a display coupled to the processor, a first image rendered from the first image data corresponding to the first field of view and a second image rendered from the second image data corresponding to the second field of view.

Various robotic surgical systems are disclosed.
