Provided are systems and methods for tactile sensing of a target tissue region of a patient in need thereof.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A method is provided for operating a powered surgical stapler having a motor unit, a controller, and a stapling assembly having a plurality of movable members that are actuatable longitudinally by the motor unit to clamp, staple, and cut tissue. The controller determines that a movable member of the stapling assembly is in a first predetermined position, and then executes an actuation algorithm to activate the motor unit to actuate the movable member longitudinally from the first predetermined position toward a second predetermined position. The controller observes an actual longitudinal displacement of the movable member between the first and second predetermined positions. The controller compares the actual longitudinal displacement to an expected longitudinal displacement and determines that the actual longitudinal displacement differs from the expected longitudinal displacement by a difference value. The controller then adjusts the actuation algorithm based on the difference value.

The invention relates to a surgical instrument comprising a handle portion or mounting portion and a functional portion and/or tip, wherein a display device is provided on the instrument and includes or enables displays which serve to assist in image-guided and/or navigation-assisted surgery. It also relates to a method for navigating a surgical instrument, wherein its position is determined and tracked by means of a medical tracking system and the position data is processed within the framework of medical navigation by means of a medical navigation system, wherein displays for navigation assistance and/or for assisting in image-guided surgery are provided on the instrument or on an element which is positionally assigned to the instrument or fastened to the instrument.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to obtain one or more parameters of a non-robotic device in a surgical space, the non-robotic device engaged by a computer-assisted surgical system; generate, based on at least the one or more parameters of the non-robotic device, guidance content for use by the computer-assisted surgical system to facilitate guided teleoperation of the non-robotic device; and provide the guidance content to the computer-assisted surgical system.

A position and tracking system for radio-based localization in an operating room, includes a receiver, a mobile cart, a processor, and a memory coupled to the processor. The mobile cart includes a robotic arm and a transmitter in operable communication with the receiver. The memory has instructions stored thereon which, when executed by the processor, cause the system to receive, from the transmitter, a signal including a position of the mobile carts in a 3D space based on the signal communicated by the transmitter and determine a spatial pose of the mobile carts based on the received signal.

Devices and methods are described for a minimally invasive procedure offering immediate relief of brain compression and prevention of subdural hematoma re-accumulation. For example, this disclosure describes devices and methods for embolization of bleeding branch vessels of the middle meningeal artery and subdural hematoma drainage in a single endovascular intervention using multimodal catheter-based technology.

A surgical instrument is disclosed. The surgical instrument comprises an end effector comprising an ultrasonic blade and a clamp arm. The clamp arm is movable relative to the ultrasonic blade to transition the end effector between an open configuration and a closed configuration to clamp tissue between the ultrasonic blade and the clamp arm. The surgical instrument further comprises an ultrasonic transducer configured to generate an ultrasonic energy output and a waveguide configured to transmit the ultrasonic energy output to the ultrasonic blade. The surgical instrument further comprises a control circuit, configured to detect an immersion of the end effector in a liquid and compensate for heat flux lost due to the immersion of the end effector in the liquid.

A method of verifying torque measurements of a reaction torque transducer of an instrument drive unit includes a controller receiving a verification signal, generating an acceptable range of torques, receiving a torque signal, comparing the torque signal to the acceptable range of torques, and stopping a motor if the torque applied by the motor is outside of the acceptable range of torques. The verification signal is indicative of the current drawn by the motor and the torque signal is indicative of torque applied by the motor.
