Abstract: A cannula may include a cannula bowl having an opening to receive an instrument configured to be advanced through the cannula, and a cannula tube extending distally from the cannula bowl. The cannula tube may have a proximal end opening, a distal end opening disposed at an opposite end of the cannula from the proximal end opening, and lateral wall defining a passage extending from the proximal end opening to the distal end opening. The lateral wall can have outer dimensions defining a waisted portion with smaller outer dimensions than a region disposed proximally or distally to the waisted portion along a length of the cannula tube.

Abstract: Gas-tight seal assemblies for use during minimally invasive surgery include various aspects. A wiper seal includes a sealing portion and a surrounding flex portion. Upper and lower faces of the sealing portions are angled with reference to an inserted instrument, the upper face's angle being more acute with reference to the instrument's shaft than the lower face's angle. The flex portion is corrugated, support ribs are in one or more corrugation grooves, and the support ribs allow the groove to easily collapse but resist the groove widening. The support ribs also prevent the sealing portion from inverting. An instrument insertion guide is positioned over the sealing portion and moves laterally with the sealing portion. A latch piece removably secures the seal assembly to a cannula. An anti-inversion piece prevents the wiper seal from inverting when an instrument is withdrawn. An assembly may include various combinations of the seal assembly, a cannula, a surgical instrument, an obturator, an endoscope, and a teleoperated medical device. The seal assembly may rotate within a cannula. The seal assembly may be used during manual or teleoperated surgery.

Abstract: A surgical instrument includes a shaft, an end effector, and a wrist coupling the end effector to the shaft. The wrist has a central channel extending along a length of the wrist. An insert guide member is positioned in the central channel. The insert guide member has an exterior lateral wall extending between a first end and a second end of the insert guide member and an interior lateral wall extending between the first end and the second end. A passage extends from the first end of the insert guide member to the second end of the insert guide member. The passage can include a first portion extending through the insert guide member between an interior lateral wall of the insert guide member and the exterior lateral wall of the insert guide member, and a second portion intersecting the exterior lateral wall of the insert guide member.

Abstract: A medical device can include a housing, a first seal structure, and a seal expander. The first seal structure can have a proximal end and a distal end, and a side wall surrounding and defining an interior chamber. A seal wall can be connected to the side wall and include an expandable opening. A seal expander can be coupled to the housing, and can be at least partially in the interior chamber of the first seal structure. The seal expander can include an expandable neck portion and a seal interface portion, the seal interface portion being near an intersection of the side wall and the seal wall.

Abstract: A cannula may include a bowl portion comprising a first opening and a second opening, and an insertion tube extending from the bowl portion. The insertion tube defines a passage extending from the second opening and terminating in a distal end opening. The passage is configured to receive an instrument to be advanced through the cannula. The insertion tube has a transparent portion extending proximally from the distal end opening, and a strengthened portion extending proximally from the transparent portion.

Abstract: An electrosurgical end effector for a surgical tool to perform teleoperated surgical operations. The electrosurgical end effector comprises a first end effector jaw; a second end effector jaw coupled to the first end effector jaw; and a coupling pin configured to rotatingly couple the first end effector jaw to the second end effector jaw so as to cooperatively rotate open and close about an axis of rotation. The electrosurgical end effector further comprises an actuation mechanism coupled to an end of the first end effector jaw to rotate the first end effector jaw about the coupling pin; an otomy feature coupled to the second end effector jaw; and a first electrical conductor to electrically couple the otomy feature to a generator. In one embodiment, the otomy feature is electrically activated by contact with a cam portion of the first end effector jaw, when opened beyond a predetermined jaw angle.

Abstract: A seal for sealing against a surgical instrument shaft includes a plurality of seal layers and a plurality of overlapping seal openings formed in the seal layers. The plurality of seal openings together can create an effective seal opening that is smaller than any of the individual overlapping seal openings. The effective seal opening is sized and shaped to seal against an instrument shaft when an instrument shaft is inserted through the effective seal opening.
