The substrate includes a proximal surface and a distal surface, with the plurality of sensing elements coupled to the distal surface of the substrate. The seal includes a base wall and a flange extending proximally from the base wall. The flange is positioned against the distal surface of the substrate to define a cavity between the base wall of the seal and the distal surface of the substrate within which the plurality of sensing elements are disposed. The cover plate is positioned over the seal and fixed to the substrate. The cover plate applies a closure force on the seal to inhibit the ingress of fluids into the cavity.

Abstract: A trocar coupling assembly includes a housing disposable in a tubular shaft of a surgical stapler. The housing has opposed openings defining a passage through the housing that is capable of receiving a trocar assembly therein. A release button is accessible through the tubular shaft for transitioning the trocar coupling assembly between a locked configuration and an unlocked configuration.

Abstract: A surgical device includes an actuator assembly including a handle, an adapter assembly extending distally from the adapter assembly, and a tool assembly supported on a distal portion of the adapter assembly. The adapter assembly includes a rotation assembly that rotatably supports the adapter assembly in relation to the actuator assembly and a wire harness that allows the actuator assembly to communicate with the tool assembly. The rotation assembly includes a stop assembly for limiting a degree of rotation of the adapter assembly in relation to the actuator assembly to prevent separation of the wire harness from communication with the actuator assembly and/or the tool assembly. The stop assembly includes a stop plate and a stop pin that are spaced from the wire harness to minimize the likelihood of damage to the wire harness during rotation of the adapter assembly in relation to the actuator assembly.

Abstract: A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes a trocar mechanism that includes a trocar member that is at least one of rotatable or articulable relative to a housing of the trocar assembly.
