Abstract: An apparatus can include a member a member to extend between a first structural member and a second structural member. The apparatus can include at least one connection point integrated with the member. The at least one connection point can be configured to facilitate a fluid coupling between a cooling line and a cooling component. The apparatus can include at least one end portion of the member. The at least one end portion can be configured to interface with a seat of at least one of the first structural member and the second structural member.

Abstract: The apparatus can include a member and an end portion. The end portion can be disposed at an end of the member. The end portion can include a first opening and a second opening. The first opening can be configured to expose a portion of a first busbar. The second opening can be configured to expose a portion of a second busbar. The first busbar can be configured to couple with the second busbar.

Abstract: A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a second rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include an articulation mechanism including a ball screw to selectively articulate the jaw assembly relative to an elongate shaft. The handle assembly can include a mechanism to lock out selection of the staple firing mode and actuation of the articulation mechanism if a reload shaft is not securely coupled to the handle assembly.

Abstract: Surface preparation for sliding surfaces can enhance wear performance for surgical instruments such as surgical staplers which include reusable mechanisms that are used multiple times with single use reload cartridges. To reduce the potential for galling wear in a metal-to-metal sliding engagement, a combination of surface hardening, surface finish, and surface coatings can be applied to metallic components of a surgical instrument. Surface hardening techniques can allow further manufacturing operations such as welding without compromising the strength of the underlying metal substrate. With stainless steel metal substrates, as surface or case hardening techniques can reduce corrosion resistance, a surface coating can be applied to inhibit surface oxidation as well as provide a barrier to metal-to-metal contact. A further lubricious coating layer such as a bone wax coating layer can enhance galling resistance.
