Publication number: 20210093311Abstract: 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.Type: ApplicationFiled: October 6, 2020Publication date: April 1, 2021Applicant: TransEnterix Surgical, Inc.Inventors: Matthew Robert Penny, James A.

Publication number: 20200297433Abstract: 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 and an overlay is displayed on the image marking the feature. Computer vision is used to detect in real time changes in the image that are indicative of the feature of interest being at least partially obscured. In response to such detected changes, a quality of the overlay is altered, e.g. to make it more bright or opaque, based on the change in visibility of the feature of interest in the image.Type: ApplicationFiled: June 25, 2018Publication date: September 24, 2020Applicant: TransEnterix Surgical, Inc.Inventors: David J.

Patent number: 8919348Abstract: A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes a rigid tube carried by a mount. Cannulas having instrument channels and steerable distal ends extend distally from the rigid tube. During a procedure using the system, the mount is supported by an operating room fixture, and instruments are advanced through the steerable instrument channels. Manipulation of the instrument handles engages actuators positioned on the mount, which steer the distal ends of the cannulas through the action of pull cables. The distal ends of the instruments may thus be steered within the body by the distal ends of the steerable cannulas.Type: GrantFiled: January 17, 2011Date of Patent: December 30, 2014Assignee: Transenterix Surgical, Inc.Inventors: Michael S.
