A system and method for performing an automated medical procedure is provided. The method may include positioning an effector unit over a patient, acquiring medical imagery of the patient, analyzing the medical imagery using at least one processor to determine a location, and positioning a subunit of the effector unit to perform the automated medical procedure at the location. The automated medical procedure may be performed using at least one of a plurality of subunits of the effector unit. The automated medical procedure may be a body fluid aspiration procedure and one of the plurality of subunits of the effector unit may include a fluid aspirating cannula. Multiple subunits may be sequentially used to perform the procedure.

A surgical instrument includes a housing including an actuator disposed thereon and an elongated shaft extending therefrom. The elongated shaft includes an end effector assembly including a pair of opposing jaw members including a knife channel defined therein. An articulation section is disposed between the housing and the end effector assembly and is configured to articulate the end effector assembly upon actuation of the actuator, the articulating section and a proximal end of the knife channel defining a first distance therebetween. A knife assembly includes a knife having a length, the proximal end including an engagement feature disposed thereon. A knife drive rod is configured to engage the engagement feature to secure the knife drive rod to the knife such that the distal end of the knife extends beyond the engagement feature and wherein the knife length is less than the length of the first distance.
