Abstract
A robotic surgical instrument includes a housing, a support plate disposed within the housing, and a shaft having a proximal end portion coupled to the support plate within the housing, a proximal segment, a distal segment, and an articulating portion interconnecting the proximal and distal segments. An end effector assembly is coupled to the distal segment of the shaft. A plurality of actuation components extends through the support plate and at least a portion of the shaft to operably couple to at least one of the end effector assembly, the articulating portion, or the distal segment to enable selective actuation of the end effector assembly. A seal configuration establishes seals against an interior annular surface of the shaft, about each actuation component of the plurality of actuation components, and within the proximal end portion of the shaft to inhibit fluid communication from the shaft into the housing.
