A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws. A control handle provided on the proximal end of the elongated shaft includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element. A force-limiting mechanism provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time.

A system to control the interaction between a user-interface of a teleoperated surgical system and an input device of the teleoperated surgical system, the system comprising a first master controller communicatively coupled to the teleoperated surgical system, a feedback control communicatively coupled to the first master controller, and a display device communicatively coupled to the teleoperated surgical system and configured to display the user interface. The feedback control is configured to restrict the movement of the first master controller based on a state of the user interface changing from a previous state.

A robotic surgical system with user engagement monitoring includes a robot assembly, a surgeon console, and a tracking device. The robot assembly includes a robotic arm coupled to a surgical instrument. The surgeon console includes a display device and a handle communicatively coupled to at least one of the robot assembly, the robotic arm, or the surgical instrument. The tracking device includes an image capture device configured to capture an image of a user position reference point. At least one of the surgeon console or the tracking device is configured to compute a position of the user position reference point based on the image; determine whether a user is engaged with the surgeon console based on the computed position; and, in response to a determination that the user is disengaged from the surgeon console, cause the robotic surgical system to operate in a safe mode.

An insertion device includes an upper casing, a lower casing and an insertion module. When the lower casing is coupled to the upper casing, an abutment portion of the lower casing limits movement of a casing engaging structure of the upper casing, such that the upper casing cannot move downwardly so as to prevent unintentional insertion operation of the insertion device.

A system for treating tissue includes a clip assembly having a pair of clip arms. Proximal ends of the clip arms engage a distal portion of a central member slidably received within a channel of a capsule to be moved between an open configuration and a closed configuration. The central member includes the distal portion and a proximal portion connected to one another via a releasable connection which releases when subject to a force exceeding a predetermined threshold level. The system also includes an applicator releasably coupled to the clip assembly. The applicator includes an outer sleeve through which a control member extends. A distal end of the control member engages a cavity of the proximal portion to move the central member relative to the capsule. A lumen of the outer sleeve is sized and shaped to slidably receive the capsule therein.

A surgical instrument for use with a robotic system is disclosed. The surgical instrument comprises a mounting portion, an elongate shaft, an articulation joint, an end effector, and a firing member. The end effector comprises an anvil and an elongate channel configured to receive a cartridge including staples. The anvil comprises a proximal end connected to the elongate channel, an outer surface, an under surface facing the elongate channel, a plurality of forming pockets defined in the undersurface, and a distal end extending below the under surface. The firing member is translatable from a starting position to an ending position to eject the staples from the cartridge during a firing stroke in response to an output motion from the robotic system. The firing member is viewable by a clinician through an opening at a proximal end of the end effector when the firing member is in the starting position.

A medical safety control apparatus that includes processing circuitry that obtains a surgical instrument-biological tissue distance, determine whether the surgical instrument-biological tissue distance is greater than a predetermined first restricted distance, in response to determining that the surgical instrument-biological tissue distance is not greater than the predetermined first restricted distance, issues an instruction for stopping a motion of an arm of a support arm apparatus that supports the surgical instrument, in response to determining that the surgical instrument-biological tissue distance is greater than the predetermined first restricted distance, determines whether the surgical instrument-biological tissue distance is greater than a predetermined second restricted distance, and in response to determining that the surgical instrument-biological tissue distance is not greater than the predetermined second restricted distance, issues a first instruction for restricting a motion speed of the arm.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, ultra-MIS techniques.

An apparatus includes a handle assembly having a body, a shaft assembly having an outer tubular member extending distally from the body, an end effector, an anvil, and a trocar latch assembly. The end effector includes a staple deck fixed relative to the outer tubular member, a staple driver that can actuate relative to the staple deck between an unfired position and a fired position, and a trocar that can actuate relative to the staple deck and the staple driver, the anvil can couple with trocar to move relative to the staple deck to define a gap distance. The trocar latch assembly includes a locking body that can actuate between an unlocked configuration and a locked configuration in response to the staple driver actuating between the unfired position and the fired position. The locking body can selective fix the trocar relative to the staple deck in the locked position.

A surgical clip applier comprising a rotatable clip cartridge is disclosed. The surgical clip applier comprises a lockout that at least locks out the crimping drive of the surgical clip applier when the rotatable clip cartridge is empty.
