One example method for detecting phases of a surgical procedure via video processing includes accessing a video of the surgical procedure and dividing the video into one or more blocks, each of the blocks containing one or more video frames. For each of the blocks, the method includes applying a prediction model on the video frames of the respective block to obtain a phase prediction for each of the video frames. The prediction model is configured to predict, for an input video frame, one of the plurality of phases of the surgical procedure. The method further includes generating an aggregated phase prediction for the respective block by aggregating the phase predictions of the video frames, and modifying the video of the surgical procedure to include an indication of a predicted phase of the respective block based on the aggregated phase prediction.

A teleoperated system comprises a display, a master input device, and a control system. The control system is configured to determine an orientation of an end effector reference frame relative to a field of view reference frame, determine an orientation of a master input device reference frame relative to a display reference frame, establish an alignment relationship between the master input device reference frame and the display reference frame, and command, based on the alignment relationship, a change in a pose of the end effector in response to a change in a pose of the master input device. The alignment relationship is independent of a position relationship between the master input device reference frame and the display reference frame. In one aspect, the teleoperated system is a telemedical system such as a telesurgical system.

A method for disengagement detection of a surgical instrument of a surgical robotic system, the method comprising: determining whether a user's head is unstable prior to disengagement of a teleoperation mode; determining whether a pressure release has occurred relative to at least one of a first user input device or a second user input device for controlling a surgical instrument of the surgical robotic system during the teleoperation mode; and in response to determining the user's head is unstable or determining the pressure release has occurred, determining whether a distance change between the first user input device and the second user input device indicates the user is performing an unintended action prior to disengagement of the teleoperation mode.

A surgical navigation system includes a first tracking unit, a second tracking unit and a processing unit. The first tracking unit captures a first infrared image of a position identification unit that includes a reference target fixed on a patient and an instrument target disposed on a surgical instrument. The second tracking unit captures a second infrared image of the position identification unit. The processing unit performs image recognition on the first and second infrared images with respect to the position identification unit, and uses, based on a result of the image recognition, a pathological image and one of the first and second infrared images to generate an augmented reality image. When both the first and second images have both the reference target and the instrument target, one of the first image and the second image with a higher accuracy is used to generate the augmented reality image.

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 operating characteristics of an instrument located in a surgical space; obtain one or more anatomical characteristics associated with the surgical space; and direct a computer-assisted surgical system to automatically perform, based on the based on the one or more operating characteristics of the device and the one or more anatomical characteristics associated with the surgical space, an operation with the instrument located in the surgical space.

A sending-side image converting apparatus sends a transmission image to a network. An image processing server performs image processing on the transmission image and sends the image generated by the image processing to the network. A receiving-side image converting apparatus outputs display images converted from the transmission image and the image generated by the image processing, to a display apparatus. Further, a controlled delay time based on a difference between a delay time in a first transmission path without via the image processing server and a delay time in a second transmission path via the image processing server is obtained on the basis of a characteristic of the display apparatus, and a timing at which the images are output to the display apparatus is controlled. The present technology is applicable to, for example, a medical-use image transmission system.

An endoscope, cannula, and obturator. The endoscope has a handle and an insertion shaft. The insertion shaft has a solid state camera. The handle contains a circuit board with circuitry for control of and receipt of signals from the camera. The handle and its components are formed of biocompatible materials. The handle is formed of inner and outer shells concentric with each other, rotation of the shells relative to each other controlled via one or more resilient components frictionally engaged between the respective shells. The handle has no metal fasteners, no adhesives, and no detachable parts small enough to travel though fluid passages of the insertion shaft, except those encapsulated by overmolding or melt-fusing to prevent dislodgement. The cannula has a connector and locking feature designed to engage with mating connectors and locking features of the obturator and the endoscope, both successively.

A system and method for navigation of a luminal network including receiving a computed tomography (CT) image data set, generating a three-dimensional (3D) model, displaying the 3D model in a user-interface on a display operatively connected to the computing device, and receiving an indication of a location of a tumor in the CT image data set. The system and method further including displaying the location of the tumor in the 3D model, receiving an indication of a margin around the tumor to achieve a desired therapy, generating a pathway to the tumor for navigation of a catheter, receiving a location of a sensor associated with a navigation catheter and registering the CT image data set with a luminal network of a patient, displaying the location of the sensor within the 3D model that substantially corresponds to the location of the sensor within the luminal network of the patient.

Methods and systems for displaying an overlay superimposed with an intraoperative image of surgical field in a medical ophthalmic procedure, such that the overlay appears at a desired depth within the image are provided. Methods and system for displaying an overlay superimposed with a stereoscopic intraoperative image pair of a surgical field in a medical ophthalmic procedure are provided.

In one embodiment, a medical image processing apparatus includes: processing circuitry configured to extract 3D blood vessel data of an object from 3D image data of the object, detect a tip position of a medical device moving in a blood vessel in real time from a fluoroscopic image of the object inputted during an operation, and calculate at least one of a recommended route and a recommended direction of the medical device from the 3D blood vessel data, a rough route of the medical device, and the tip position of the medical device; and a terminal device configured to display a 3D blood vessel image of the object generated from the 3D blood vessel data and to designate the rough route of the medical device on the 3D blood vessel image.
