    Abstract: The present disclosure provides a surgical instrument, such as a tissue sealing instrument, having a staple cartridge with a staple pusher and a staple; and a drive member configured to translate distally through the instrument. The drive member includes a lateral projection configured to engage the staple pusher and drive the staple into tissue. The lateral projection of the drive member has a height substantially less than the height of the staple cartridge, thereby requiring less clearance as it translates through the staple cartridge. In addition, the lateral projection has a smaller footprint than conventional drive members resulting in a more compact distal tip on the staple cartridge, which allows for a more compact and maneuverable surgical instrument.

    Abstract: Sealing assemblies and methods are disclosed for sealing a surgical instrument having an internal drive shaft subject to lateral displacement. A sealing assembly includes a rigid portion shaped to interface with an instrument shaft of the surgical instrument. A laterally oriented slot is open at a radially perimeter location and configured to receive an o-ring seal via the perimeter location. Apertures are disposed on opposing sides of the slot and open to the slot. The apertures are configured to receive the drive shaft there through and are larger than the drive shaft to accommodate lateral displacement of the drive shaft. The slot includes opposing internal sides spaced to interface with opposed axial surfaces of the o-ring seal. The seal inhibits axial transmission of an insufflated gas and/or bodily fluids while accommodating lateral displacement of the drive shaft.

    Abstract: End effectors with redundant closing mechanisms, and related tools and methods are disclosed. The disclosed end effectors may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises an elongate shaft having a proximal end and a distal end, a tool body disposed at the distal end of the shaft, a jaw movable relative to the tool body between a clamped configuration and an open configuration, a first actuation mechanism coupled with the jaw and operable to vary the position of the jaw relative to the tool body between the clamped configuration and the open configuration, and a second actuation mechanism coupled with the jaw. The second actuation mechanism has a first configuration where the jaw is held in the clamped configuration and a second configuration where the position of the jaw relative to the tool body is unconstrained by the second actuation mechanism.

    Abstract: Surgical devices, systems, and related methods provide automated assessment of the status of a surgical instrument. A surgical device is configured to staple tissue via a replaceable stapler cartridge. The surgical device includes a pusher member configured to articulate the stapler cartridge to deploy staples. The surgical device includes an actuation mechanism that articulates the pusher member and a control unit configured to control operation of the actuation mechanism to attempt move the pusher member from a first position to a second position subject to an output limit for the actuation mechanism and determine an attribute of the stapler cartridge based on an amount of movement of the pusher member achieved. The determined attribute can indicate a type of the stapler cartridge selected from different stapler cartridges, whether the stapler cartridge has already been fired, or that no stapler cartridge is mounted to the surgical device.

    Abstract: Surgical tools having a two degree-of-freedom wrist, wrist articulation by linked tension members, mechanisms for transmitting torque through an angle, and minimally invasive surgical tools incorporating these features are disclosed. An elongate intermediate wrist member is pivotally coupled with a distal end of an instrument shaft so as to rotate about a first axis transverse to the shaft, and an end effector body is pivotally coupled with the intermediate member so as to rotate about a second axis that is transverse to the first axis. Linked tension members interact with attachment features to articulate the wrist. A torque-transmitting mechanism includes a coupling member, coupling pins, a drive shaft, and a driven shaft. The drive shaft is coupled with the driven shaft so as to control the relative orientations of the drive shaft, the coupling member, and the driven shaft.

    Abstract: A surgical instrument includes an elongated shaft and an end effector coupled to the shaft. The end effector includes a first member, a knife member, and a second member. The first member is movable towards a distal end of the end effector. The knife member is pivotally coupled to the first member. The second member is movable towards the distal end of the end effector. The knife member is configured to be in a cutting position during a translation of the first and second members towards the distal end of the end effector. The knife member is rotatable relative to the first member to stow the knife member into a non-cutting position after the translation of the first and second members towards the distal end of the end effector.

    Abstract: A cartridge of a surgical instrument includes a housing, a drive member, and a knife member. The knife member is driven distally by the drive member and is configured to cut when moved distally. During an initial distal movement of the drive member, the knife member is coupled with the housing to restrain the knife member from moving distally. Subsequent to the initial distal movement of the drive member, the drive member drives the knife member toward the distal end.
