    摘要： A surgical device includes an adapter assembly including a tubular housing having a proximal end portion configured to couple to a handle assembly, and a load sensing assembly disposed with the tubular housing. The load sensing assembly is configured to measure a load exerted on the tubular housing and includes: a sensor body including a pocket defined therein; a load sensor circuit disposed within the pocket and coupled to the sensor body; a signal processing circuit disposed within the pocket and electrically coupled to the load sensor circuit; a cover defining a cavity and disposed over the pocket and enclosing the load sensor circuit and the signal processing circuit therein, the cover being coupled to the sensor body thereby forming a first hermetic seal therebetween; and a thermal management material disposed within the cavity and in contact with the load sensor circuit and the signal processing circuit.

    摘要： A stapling device includes a handle assembly, an adaptor assembly extending from the handle assembly, and a reload assembly supported on a distal end portion of the adaptor assembly. The reload assembly includes a shell housing, a staple cartridge, a first seal, a staple actuator, and a knife carrier. The first seal is disposed within a cavity of the shell housing and defines a staple actuator opening and a knife carrier opening. The staple actuator includes a proximal leg extending proximally therefrom and through the staple actuator opening of the first seal to provide a fluid seal therebetween. The knife carrier includes a proximal body portion extending proximally therefrom and through the knife carrier opening of the first seal to provide a fluid seal therebetween.

    摘要： A stapling device includes a handle assembly and an adaptor assembly extending from the handle assembly and including a sealed trocar assembly. The trocar assembly includes a trocar housing defining a lumen, an annular seal having an inner annular surface defining an inner opening, and a trocar disposed within the lumen of the trocar housing, through the inner opening of the annular seal, and movable through the lumen of the trocar and the inner opening of the annular seal, and a seal retainer operably coupled to the trocar housing and the annular seal. The trocar includes an elongate body portion having a distal end and a trocar member extending distally from the distal end of the elongate body portion.

    摘要： A surgical stapling apparatus includes an end effector and an electronics assembly, the end effector having an anvil assembly and a cartridge assembly. The anvil and cartridge assemblies are positionable between an open position and a closed position to selectively grasp tissue therebetween. The electronics assembly is supported in the end effector and configured to determine a condition of the grasped tissue based on an amount of current in an electrical circuit defined by the anvil and cartridge assemblies.
