A surgical instrument is disclosed comprising an end effector, a frame, an articulation system configured rotate the end effector relative to the frame, and a firing system configured to perform a firing stroke within the end effector. The firing system is selectively engageable with the articulation system to rotate the end effector. In such instances, the firing system cannot perform the firing stroke until the firing system has been operably decoupled from the articulation system.

An approach is provided for image guided procedures. The approach includes acquiring image data of at least one object of a subject, in which the acquired image data is registered to one or more coordinate systems. The approach includes receiving the acquired image data. The approach includes displaying, on one or more smartglasses, one or more superimposed images over a portion of the subject. The one or more superimposed images may be related to the acquired image data. The approach includes aligning the one or more superimposed images to correspond with a position of the at least one object.

A composite image generation system comprises: a position information detection device that detects position information about a predetermined spot in a real space; and a processing device that generates a composite image in which a separately acquired superimposed image is overlaid onto a desired region in a camera image of the real space captured by a movably placed video camera, based on the detected position information. In the processing device, after performing an initial setting that sets a global coordinate system that serves as a reference when generating the composite image, the initial setting being performed while each optical marker is in a stationary state, position information about a peripheral marker used during the initial setting is reset according to a recognition state of the peripheral marker provided at a predetermined spot presumed to be disposed in the stationary state and a detection state from an acceleration sensor.

An electronic system for a surgical instrument is disclosed. The electronic system comprises a main power supply circuit configured to supply electrical power to a primary circuit. A supplementary power supply circuit configured to supply electrical power to a secondary circuit. A short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. The supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit. The supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.

Provided are robotic systems and methods for navigation of luminal network that can improve strain-based shape sensing. In one aspect, the system can compare strain-based shape data to shape data determined based on robotic data (e.g., kinematic model data, torque measurements, mechanical model data, command data, etc.) and adjust the strain-based shape data as necessary. Any portion of the strain-based shape data can be adjusted, weighted differently, or discarded based on the comparison. For example, data from trustworthy sources may indicate that the shape of an instrument exhibits or should exhibit one or more characteristics. If the system determines that any portion of the strain-based shape data is not in agreement with such characteristics, the system may adjust the portion of the strain-based shape data such that the adjusted strain-based shape data is in agreement with the characteristics of the instrument.

A method of operating a surgical instrument is disclosed. The surgical instrument includes an electronic system comprising an electric motor coupled to the end effector; a motor controller coupled to the motor; a parameter threshold detection module configured to monitor multiple parameter thresholds; a sensing module configured to sense tissue compression; a processor coupled to the parameter threshold detection module and the motor controller; and a memory coupled to the processor. The memory stores executable instructions that when executed by the processor cause the processor to monitor multiple levels of action thresholds and monitor speed of the motor and increment a drive unit of the motor, sense tissue compression, and provide rate and control feedback to the user of the surgical instrument.

A method of controlling an instrument involves measuring strain of one or more optical fibers associated with an elongate shaft of an instrument, determining a first shape estimation of the elongate shaft based on the measured strain, determining, based on the measured strain, a strain-indicated characteristic of the elongate shaft with respect to a mechanical condition of the elongate shaft, determining an expected range of the mechanical condition of the elongate shaft, determining that the strain-indicated characteristic is outside of the expected range of the mechanical condition, and in response to the determination that the strain-indicated characteristic is outside of the expected range, determining a second shape estimation of the elongate shaft, the second shape estimation being based to a lesser degree on the measured strain compared to the first shape estimation.

Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined. using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, of external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

A tracking system and a tracking method using the same are disclosed. The tracking system includes a marker, a camera unit, a first inertial measuring unit, a second inertial measuring unit and a tracking processing unit. The marker is fixed on the measurement object, and the camera unit outputs a marker image by photographing the marker. The first inertial measuring unit is fixed on the camera unit, and measures and outputs first inertia comprising first accelerated velocity and first angular velocity. The second inertial measuring unit is fixed to one of the measurement object and the marker, and measures and outputs second inertia comprising second accelerated velocity and second angular velocity. The tracking processing unit primarily extracts the position and the posture of the measurement object using the marker image, and secondarily extracts the position and the posture of the measurement object using the first and second inertias.

Provided is a neuroprotection apparatus including a scalp temperature measurement acquisition device for acquiring scalp temperature measurements at a plurality of locations on a patient's scalp during an induced hypothermia and a neuroprotection processor for processing the scalp temperature measurements for determining real time patient temperature information for display on a human head image on a display device during the induced hypothermia.
