A surgical hub for use with a surgical system in a surgical procedure performed in an operating room is disclosed. The surgical hub comprises a control circuit configured to generate a first image of a surgical site from a real-time imaging source, receive a second image of the surgical site from a non-real-time image source, align the first image and the second image, generate a representation of the surgical site based on the first image and the second image as aligned, display the representation on a display screen, receive a first user selection to overlay hidden structures on the representation, receive a second user selection to manipulate the representation, and adjust the representation based on the second user selection.

A method for generating and updating a three-dimensional representation of a surgical site based on imaging data from an imaging system is disclosed. The method comprises the steps of generating a first image of the surgical site based on structured electromagnetic radiation emitted from the imaging system, receiving a second image of the surgical site, aligning the first image and the second image, generating a three-dimensional representation of the surgical site based on the first image and the second image as aligned, displaying the three-dimensional representation on a display screen, receiving a user selection to manipulate the three-dimensional representation, and updating the three-dimensional representation as displayed on the display screen from a first state to a second state according to the received user selection.

Aspects of the present disclosure are presented for systems and methods for identifying characteristics of a return pad in a monopolar electrosurgical system using contact quality monitoring (CQM) and near field communication (NFC) signals. In some aspects, resistance or impedance materials are sensed that may help identify what kind of return pad is being used, including what is the structure of the pad. In some aspects, NFC signals are used to identify characteristics of the return pad. In some aspects, the grounding or return pad may include two separate materials that form an interconnecting or interwoven mesh and both act as non-active electrodes when both contact the patient. A non-zero impedance may separate conductive lines connecting the two separate materials that may be analyzed to obtain a defining signature about that is linked to structural characteristics about the return pad.

A surgical tool includes a drive housing removably coupled to a tool driver of a robotic surgical system, a shaft extending from the drive housing, an end effector arranged at an end of the shaft, and a computer system. The computer system is programmed to send a command signal to a motor of the tool driver to drive rotation of a drive shaft mounted within the drive housing, monitor torque and rotational motion of the motor with a torque sensor and a rotary encoder, respectively, in communication with the computer system, measure an unexpected change in the torque or the rotational motion of the motor with the torque sensor or the rotary encoder when the surgical tool is manually bailed out by manually rotating the drive shaft and backdriving the motor, report the unexpected change as a bailout signal, and disable the surgical tool once the bailout signal is received.

A surgical robotic system has a tool drive coupled to a distal end of a robotic arm that has a plurality of actuators. The tool drive has a docking interface to receive a trocar. The system also includes one or more sensors that are operable to visually sense a surface feature of the trocar. One or more processors determine a position and orientation of the trocar, based on the visually sensed surface feature. In response, the processor controls the actuators to orient the docking interface to the determined orientation of the trocar and to guide the robotic arm toward the determined position of the trocar. Other aspects are also described and claimed.

An endoluminal punch system including a sheath and dilator. The endoluminal punch may include energy delivery system capable of being transmitted from the proximal end to the distal end of the endoluminal punch to assist with tissue crossing and incisions. The dilator may include selectively deployable cutting mechanism to create incisions in tissue that are larger than their basic external diameter. The system may also be configured to reduce the risk of generating plastic emboli during insertion of the endoluminal punch.

A system including an instrument having a working tool configured to penetrate a tissue; a sensor configured to generate in real-time one or more torque signals related to torque of the working tool; a controller in operative communication with the sensor and configured to receive the one or more torque signals. The controller processes the torque signals into one or more processed signals representative of torque, energy, power or a combination thereof. The system also includes a display providing to the user in real-time the one or more processed signals. Related devices, systems, methods, and articles are provided.

A surgical robotic component comprising an articulated terminal portion, the terminal portion comprising: a distal segment having an attachment connected thereto, an intermediate segment, and a basal segment whereby the terminal portion is attached to the remainder of the surgical robotic component. The terminal portion further comprises a first articulation between the distal segment and the intermediate segment, the first articulation permitting relative rotation of the distal segment and the intermediate segment about a first axis, and a second articulation between the intermediate segment and the basal segment, the second articulation permitting relative rotation of the intermediate segment and the basal segment about a second axis. The intermediate segment comprises: a third articulation permitting relative rotation of the distal segment and the basal segment about third and fourth axes, a first torque sensor configured to sense torque about the third axis, and a second torque sensor configured to sense torque about the fourth axis. The first, second and third articulations are arranged such that in at least one configuration of the third articulation the first and second axes are parallel and the third and fourth axes are transverse to the first axis.

A system for determining the torsion of a screw is provided. The system generally comprises a first washer, second washer, spring, radio frequency identification (RFID) tag, and interrogation device. A screw is inserted through the system and provides the compression force necessary to bring the first washer and second washer separated by the spring in contact with one another, thus creating a complete circuit from the first circuit portion and second circuit portion of the signal transmitter. The interrogation device is used to send and receive information to and from the signal transmitter. An encasing may be used to encapsulate the first washer, second washer, spring, and signal transmitter in a way such that they are protected from the environment.

An example method for detecting stability of a medical implant is provided. The method includes (a) applying a force to the medical implant with a probe, (b) based on the applied force, determining a response signal associated with a vibration of the medical implant, (c) comparing the determined response signal with a computer model of the medical implant, and (d) based on the comparison, determining an angular stiffness coefficient of the medical implant, wherein the angular stiffness coefficient indicates a stability of the medical implant.
