  • Publication number: 20260144544
    Abstract: An apparatus includes a first and second elongate member that can releasably couple together to in order to cooperate to clamp and staple tissue, a latch member that can latch the first and second elongate member to clamp tissue, a firing assembly that can sever and staple clamped tissue, and a clamp force measuring assembly. The clamp force measuring assembly can measure a parameter associated with a clamping force imparted on the first and second stapling surfaces while clamping tissue, and process and communicate the measured parameter to be compared with a predetermined limit associated with successful staple formation.

  • Publication number: 20260069270
    Abstract: An apparatus including a first jaw to selectively receive a staple cartridge and define a longitudinal jaw axis. The apparatus further includes a second jaw. The first and second jaws being able to cooperate to clamp and staple tissue. The apparatus further including a knife to actuate relative to the first jaw and the second jaw along the longitudinal jaw axis while the staple cartridge is housed within the first jaw to thereby cut and staple tissue clamped by the first and second jaws. The knife defines a longitudinal knife axis that extends along the longitudinal jaw axis. The apparatus further includes a lock rotatable relative to the knife about the longitudinal knife axis between an unlocked configuration and a locked configuration. The lock being able to inhibit distal actuation of the knife in the locked configuration and permit distal actuation of the knife in the unlocked configuration.

  • Patent number: 12390220
    Abstract: A stapling assembly for a surgical instrument includes a body extending along a longitudinal axis and having an upper deck, a plurality of pockets extending through the upper deck for receiving respective staples and arranged in at least two longitudinal rows, a plurality of staple drivers, and a staple driver actuator. The stapling assembly also includes a plurality of pocket extenders extending upwardly from the upper deck. Each pocket extender has a respective top surface. The stapling assembly further includes at least one upwardly-facing surface configured to contact an adhesive of an adjunct for securing the adjunct to the stapling assembly. The at least one upwardly-facing surface is disposed at least partially between at least a portion of the upper deck and the top surfaces of the plurality of pocket extenders, and spans laterally at least partially across at least two longitudinal rows of the plurality of pockets.

  • Patent number: 12324583
    Abstract: A surgical stapler kit includes a surgical stapler having a body, a shaft, and an end effector. The kit includes a first staple cartridge having a first cartridge body and a first sled, and a second staple cartridge having a second cartridge body and a second sled. When the first staple cartridge is at least partially seated within a cartridge jaw with the first sled in a proximal undisplaced position, a knife drives the first sled distally to deploy staples from the first cartridge body. When the second staple cartridge is at least partially seated within the cartridge jaw with the second sled in a proximal undisplaced position, the knife advances distally into a lockout position before causing any staples to be deployed from the second cartridge body.

  • Patent number: 5720402
    Abstract: A cap and container combination wherein the cap fits about the container in at least two closure positions. Two circumferential bands are provided around the skirt of the cap and there is an internal thread which engages an external thread about the container neck. In the first position, one band of the cap engages a circumferential slot about the container. The internal thread seals with the top of the container. The first band is removed and the container opened by removing the cap. In the second position, the second band engages the slot and the threads engage each other. In the second position, the second band is located about the container. It remains in position when and after the cap is removed. Tampering of the container and cap can be visually detected with this configuration. A bead about the container is formed of a reduced cross-section in portions circumferentially around the cap. This facilitates assembly and disassembly of cap and container.
