  • Patent number: 10631867
    Abstract: A surgical instrument includes an anvil selectively coupleable to a stapling head assembly and a trigger operable to fire staples into tissue compressed between the anvil and the stapling head assembly. In some versions, a lockout member may engage a securing feature to prevent actuation of the anvil relative to the stapling head assembly. For instance, a tab may engage a slot on an actuator, a screen door lock may provide frictional resistance or engage teeth on the actuator, a door may actuate into engagement with one or more recesses, geared teeth may mesh with teeth on the actuator, the lockout member may include a ratcheting assembly to engage actuator, and/or a push button may actuate into a recess while disengaging the lockout member. Alternatively, in some versions, the trigger actuation assembly may be disengaged prior to firing. An anvil position indicator may restrict engagement of the trigger actuation assembly.

  • Publication number: 20190151130
    Abstract: An apparatus comprises a sleeve, a seal, and an anchor assembly. The sleeve is flexible and non-permeable and is configured to fit in a duodenum. The seal is positioned at the proximal end of the sleeve and is configured to seal the proximal end of the sleeve against the stomach mucosa, the pylorus, or the duodenum mucosa. The anchor assembly comprises a pair of atraumatic anchor ends and a resilient member positioned between the anchor ends. At least a portion of the resilient member extends along at least a portion of the length of the sleeve. The resilient member is configured to bias the anchor ends generally toward each other, to thereby substantially anchor the sleeve in the duodenum. The sleeve is configured to prevent chyme from contacting the mucosa of the duodenum; and to prevent enzymes excreted in the duodenum from mixing with chyme in the duodenum.

  • Patent number: 10245030
    Abstract: A surgical instrument comprising an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective articulation relative to the elongate shaft assembly about an articulation axis that is transverse to the shaft axis. An articulation cable is coupled to the surgical end effector at a point of attachment and is journaled on a proximal pulley that is supported on the elongate shaft assembly. The proximal pulley defines a proximal pulley axis that is located a tension distance from the point of attachment. An articulation driver is coupled to the articulation cable for selectively causing the articulation cable to rotate about the proximal pulley in first and second articulation directions. An adjustable tensioning assembly interfaces with the proximal pulley to selectively adjust the tensioning distance.

  • Patent number: 10226246
    Abstract: A surgical instrument includes a handle assembly having a trigger operable to fire a staple driver to staple tissue. The instrument includes a pointed rod to which an anvil may be coupled. An anvil detection feature is included to determine when the anvil is coupled to the rod. In some versions, the anvil detection feature comprises a translatable rod that inhibits a lockout feature from disengaging. In other versions, an anvil sensing tube is disposed about the pointed rod and interferes with actuation of the trigger in a first position. A recess in the tube permits trigger to actuate when the anvil sensing tube is in the second position. Alternatively, a resilient tab is coupled to the pointed rod and resists actuation of the staple driver. A trigger lockout assembly may include a spring-loaded button that “pops” out when a push rod is actuated, thereby freeing a pivotable lockout feature.
