Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridge for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch for maintaining the locking member in the disabled position. The switch may be further configured to operate as a reload detection mechanism for determining the type of reload present in the surgical stapling instrument.

Abstract: A needle driver device includes an arc-shaped track and an arc-shaped needle configured to be received in the arc-shaped track. The arc-shaped needle is moveable along a curved path including the arc-shaped track. The needle driver device further includes a rotary drive mechanism and a needle driver link. The needle driver link has a distal end portion configured to removably engage the arc-shaped needle and a proximal end portion coupled to the rotary drive mechanism. The needle driver device also includes a guide member coupled to the needle driver link and defining a pivot location of the needle driver link between the distal end portion and the proximal end portion of the needle driver link. The needle driver link is rotatable about the pivot location, and the guide member is moveable in response to movement of the needle driver link.

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: Stapler cartridges and surgical apparatus that include a stapler cartridge can include a knife that retracts into the stapler cartridge after cutting stapled tissue to prevent an operator being cut by the knife during replacement of the used stapler cartridge with a new stapler cartridge. A stapler cartridge includes a staple pushing shuttle, a knife member slidably coupled with the staple pushing shuttle, and a cartridge body. The staple pushing shuttle is slidably coupled to the cartridge body. The cartridge body includes a guide track engaged by the knife member and configured so that a cutting blade of the knife member protrudes from the cartridge body during a first portion of a distal movement of the staple pushing shuttle and the cutting blade is retracted into the cartridge body during a second portion of the distal movement of the staple pushing shuttle.

Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position. The instrument may further include a stapler cartridge including an annular pin configured to be engaged by a drive member at a an axial position to create a detectable resistance for reload detection by a control unit to identify the type of stapler cartridge present in the surgical stapling instrument.

Abstract: A method of using a medical instrument can include applying a distally-directed or proximally-directed load via a drive member to an end effector coupled to an elongated shaft via a wrist assembly so as to actuate the end effector; and reacting the distally-directed or proximally-directed load to an inner link of the wrist assembly that is pivotally coupled to a first outer link and a second outer link. The wrist assembly can be actuatable via drive cables and reacting the load maintains the first outer link interfaced with the second outer link in the absence of tension in the drive cables.
