  • Publication number: 20240006048
    Abstract: A method of reclaiming portions of a surgical kit having a surgical instrument includes disassembling the surgical instrument and determining a disposal methodology of the surgical kit. Furthermore, reclaiming further includes verifying reuse capacity of a portion of the surgical instrument and determining a waste stream for the portion of the surgical instrument. The method also includes disassembling the portion of the surgical instrument from a remainder of the surgical instrument at a predetermined region of the surgical instrument to thereby reclaim the portion of the surgical instrument according to the waste stream.

  • Publication number: 20240000474
    Abstract: A surgical instrument includes a shaft assembly, an end effector, an energy drive system, a circuit assembly, and a body assembly. Body assembly has a first shroud portion removably affixed to a second shroud portion by a shroud coupling in a connected state. The shroud coupling detaches the first shroud portion from the second shroud portion in a disconnected state. The first and second shroud portions in the connected state encloses and inhibits access to at least a portion of at least one of the circuit assembly or the energy drive system. The first and second shroud portions in the disconnected state allow access to the at least the portion of at least one of the circuit assembly or the energy drive system for removal of the at least the portion of at least one of the circuit assembly or the energy drive system.

  • Patent number: 11786243
    Abstract: A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component. The 3D-printed component can include a plastic body and one or more metal substrates with interlocking features embedded in the plastic body. The surgical stapling assembly can include a firing member having a flexible portion configured to flex more readily that adjacent portions of the firing member.
