A surgical instrument holder includes a carriage, a housing, and a drive assembly. The carriage is configured for engagement to a surgical robotic arm and for supporting an instrument drive unit. The housing extends from the carriage and defines a channel. The drive assembly includes a pulley, a belt, and an annular member. The pulley is rotatably disposed within the housing and in operable engagement with a motor of the carriage such that actuation of the motor rotates the pulley. The belt is rotatably disposed within the housing and in operable engagement with the pulley such that rotation of the pulley effects rotation of the belt. The annular member is disposed within the channel of the housing and configured for non-rotatable receipt of an instrument drive unit. The annular member is in operable engagement with the belt such that rotation of the belt effects rotation of the annular member.

A wound retractor includes a sleeve with proximal and distal ends, an inner ring inside the sleeve between the proximal and distal ends, and an outer ring outside the sleeve between the proximal and distal ends. The inner ring includes a tapered outer surface that increases in diameter from a proximal end of the inner ring toward a distal end of the inner ring. The outer ring includes a tapered inner surface that increases in diameter from a proximal end of the outer ring toward a distal end of the outer ring. A portion of the sleeve is captured between the tapered outer surface and the tapered inner surface.

A surgical instrument including an end effector, a shaft assembly defining a longitudinal axis extending proximally from the end effector, a first drive operatively connected to a first portion of at least one of the end effector or the shaft assembly, and an activating mechanism operatively connected to the first drive. The first drive longitudinally translates relative to the longitudinal axis from a first drive position toward a second drive position to respectively actuate the first portion from a first portion position toward a second portion. The activating mechanism selectively direct translation of the first drive from the first drive position toward the second drive position by rotating from a first rotational body position toward a second rotational body position or translating from a first translational body position toward a second translational body position.

A surgical system includes a manipulator, a surgical tool and a control system. The manipulator includes a manipulator mounting base, a pitch mechanism, a roll mechanism and a redundant rotation mechanism. The surgical tool is supported by the manipulator and has a tool shaft axis. The pitch mechanism rotates the surgical tool around a pitch axis. The roll mechanism rotates the surgical tool around a roll axis transverse to the pitch axis. The redundant rotation mechanism rotates the surgical tool around a redundant rotation axis. Each of the tool shaft axis, the pitch axis and the roll axis intersect at a remote center. The control system is configured to electronically communicate with and control operation of the manipulator to articulate the surgical tool during surgery.

Disclosed is a console for operating an actuating mechanism, relating to the technical filed of automatic control, and being for use in resolving the technical problem of shift of a controller under the influence of gravity. The console for operating an actuating mechanism includes a controller and a support base. The controller is constrained in both the longitudinal direction and the vertical direction, so that connection between the controller and the support base is tight and reliable, and no displacement would occur in any of three directions (i.e., the longitudinal direction, the horizontal direction, and the vertical direction). Thus, the phenomenon that position information given by the controller is inaccurate due to shift of the controller under the influence of the gravity after long-term usage can be avoided, thereby removing the factors affecting success of surgery, and ensuring the success rate of the surgery.

Described herein is an apparatus for guiding an elongated flexible instrument, the apparatus comprising a variable-length support assembly adapted to maintain a length of the elongated flexible instrument in a fixed configuration relative to the variable-length support assembly as the variable-length support assembly is moved along a longitudinal axis. The variable-length support assembly includes a plurality of linkages connected in series along the longitudinal axis, and the variable-length support assembly has a compact configuration and an expanded configuration.

A medical manipulator system according to the present invention is provided with: a manipulator; a manipulator channel; a route that extends along the manipulator channel; a shape sensor that detects shape information of the manipulator channel; a shape-sensor driving portion that causes the shape sensor to be driven; a manipulator driving portion that causes the manipulator to be driven; a positional-information calculating portion that calculates positional information of the shape sensor on the basis of a driven amount of the shape-sensor driving portion; a shape estimating portion that estimates a bent shape of the manipulator on the basis of the shape information of the manipulator channel and the positional information; a control-parameter calculating portion that calculates a control parameter of the manipulator from the bent-shape information; and a manipulator controller that controls the manipulator on the basis of the control parameter.

A robotic system is configured to automatically trigger a robotic action based on an identified phase of a medical procedure. The robotic system includes a video capture device; a robotic manipulator; one or more sensors; an input device; and control circuitry. The control circuitry is configured to: determine a first status of the robotic manipulator based on sensor data from the one or more sensors; identify a first input from the input device for initiating a first action of the robotic manipulator; perform a first analysis of a video of a patient site captured by the video capture device; identify a first phase of the medical procedure based at least in part on the first status of the robotic manipulator, the first input, and the first analysis of the video; and trigger a first automatic robotic action of the robotic manipulator based on the identified first phase.

A surgical robotic system that includes a surgical table that is configured to hold a patient and a magnetic latch. The magnetic latch has a ferromagnetic plate, a permanent magnet that produces a first magnetic field and that attracts the ferromagnetic plate to thereby couple a robotic arm to the surgical table, and a cancelling coil, which when energized, produces a second magnetic field that opposes the first magnetic field to thereby uncouple the robotic arm from the surgical table.

A medical device includes a medical instrument guide. The medical instrument guide includes a guide body, The guide body includes a foam and a bore through the foam. The foam includes a plurality of open cells that hold a biocompatible lubricant. And, the bore is sized to receive a medical instrument shaft and is defined at least in part by a surface exposing the plurality of open cells holding the biocompatible lubricant to the medical instrument shaft.
