A cartridge for use with a surgical instrument includes a curved body and a deck defined by the curved body and configured to clamp tissue against an anvil. A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot is formed in the deck and is configured to slidably receive a cutting member therethrough. The deck includes a sloped deck portion that slopes away from the arcuate slot in a direction transverse to a length of the arcuate slot. The sloped deck portion is configured to provide varied compression of tissue across a width of the deck.

A cartridge for use with a surgical instrument includes a curved body and a deck configured to clamp tissue against an anvil. A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot formed in the deck is configured to slidably receive a cutting member therethrough. An opening formed in the deck adjacent to an end of the arcuate slot is configured to slidably receive a pin therethrough. The cartridge further includes a raised surface offset from the deck and extending circumferentially about at least a portion of the opening. The raised surface is configured to clamp tissue against the anvil to thereby fix the tissue relative to the opening.

A surgical instrument includes a body assembly, a shaft assembly that releasably attaches to the body assembly, and an end effector at a distal end of the shaft assembly. The body assembly includes a first support structure, a first electrical contact supported by the first support structure, and a first sealing surface. The shaft assembly includes a second support structure, a second electrical contact supported by the second support structure, and a second sealing surface. When the shaft assembly attaches to the body assembly, the first and second electrical contacts electrically couple to establish an electrical connection therebetween, and the first and second sealing surfaces sealingly engage to block fluid from reaching the electrical connection. At least one of the first or second sealing surfaces is movable relative to the respective support structure to facilitate the sealing engagement.

Surgical instrument with compressible electrical connector

A surgical instrument includes a body assembly, a shaft assembly that releasably attaches to the body assembly, and an end effector at a distal end of the shaft assembly. The body assembly includes a first electrical contact and a first sealing portion. The shaft assembly includes a second electrical contact and a second sealing portion. The first and second electrical contacts are configured to electrically couple together to establish an electrical connection therebetween when the shaft assembly is attached to the body assembly. The first and second sealing portions are configured to sealingly engage one another when the shaft assembly is attached to the body assembly to establish a liquid-tight seal that surrounds the electrical connection.

Seal for surgical instrument

A powered surgical instrument includes a shaft assembly and a handle assembly. The shaft assembly includes a first electrical connector and a flexible element positioned adjacent to the first electrical connector. The handle assembly includes a second electrical connector. The handle assembly is configured to attach to the shaft assembly. The second electrical connector is configured to electrically connect with the first electrical connector when the handle assembly is attached to the shaft assembly. The flexible element is configured to create a liquid-resistant seal against the handle assembly and adjacent to the electrical connection of the first and second electrical connectors when the shaft assembly and the handle assembly are attached.
