A system and method for providing visual assistance to a practitioner during a medical suturing procedure. Real time images of the suture site are captured and displayed on an image display. The images are analyzed in real time to detect the suture needle, suture penetration sites, relevant tissue, adjacent tissue edges or other features of interest in the visual images. Based on the orientation of, or relationship between, the detected features of interest, overlays are generated and displayed on the image display to inform the user about the suturing task that is underway, such as the anticipated needle path, the suture spacing, or the separation between sutures and adjacent tissue edges.

A system and method for displaying tissue information on a display screen includes a camera capturing an image of an anatomical working site including a surgical instrument, and a display displaying the image. A tissue information detection device determines information about the health, pathology etc. of tissue in contact with a surgical instrument, or about an interaction between the surgical instrument and the tissue. The system renders overlays depicting the tissue information with the image on the display.

A user interface for a surgical robotic system includes a plurality of handles, each removably attachable to a user interface assembly by a quick release connector. The selection of handles can include handles of varying size, degree of complexity, handles adapted for laparoscopic motion, handles adapted for true cartesian motion or handles customized to surgeon anthropometric data, etc.

In a system and method conveying suture force information in surgery, real times images of a surgical site are captured and displayed on a display. A suture is engaged using at least one surgical instrument, which in some cases is a robotic surgical instrument. The system determines a tension in the suture using force data obtained from force sensors associated with the instrument or a robotic manipulator used to manipulate the instrument, or using computer vision techniques applied to the captured images. An overlay is generated and displayed on the display depicting the determined tension.

A system and method allow creation of surgical annotations during surgery. A digital image of a treatment site in a region of patient anatomy is captured using a camera and is displayed on an image display. The system displays an overlay marking an anatomic region of interest in the displayed image. During the course of the surgery, panning of the image results in the anatomic region of interest being outside the displayed field of view. In response to user input, the displayed image is subsequently panned such that the anatomic region of interest and the displayed overlay return to the displayed field of view.

A system for determining relative positions of subsystems of a robot-assisted surgical system includes a subsystem component including a plurality of manipulator arms and a surgeon console. Each subsystem component includes at least one of an optical tracker and a light emitter. Image data from the optical trackers is analyzed to determine the relative positions of the subsystems.

A system for measuring distances within a surgical site includes a camera positionable to capture 3D image data corresponding to a treatment site. Using the image data, the system determines the relative 3D positions of identified measurement points at the treatment site captured in the images, and it estimates or determines the distance between the measurement points. Output is generated communicating the measured distances to the user. The measurement taken follows the 3D topography of the tissue positioned between the measurement points.

A surgical system includes a drive unit on a support. The drive unit includes motors or other actuators and a plurality of output elements arranged such that operation of each drive unit linearly translates a corresponding one of the output elements. A surgical device has actuation elements extending through an elongate shaft to a distal articulation section, and an input subsystem carried at the proximal end of the shaft. Linear translatable input elements or pistons of the input subsystem are each associated with a corresponding one of the actuation elements. The input and output elements are positioned such that operation of an actuator linearly translates an output element, causing linear translation of a corresponding input element and engagement of an actuation element. A sterile drape is positionable between the input elements and the output elements.

A system and method for augmenting an endoscopic display during a medical procedure including capturing a real-time image of a working space within a body cavity during a medical procedure. A feature of interest in the image is identified to the system using eye tracking input, and a graphical tag is displayed on the image marking the feature.
