Abstract: A medical instrument includes an instrument shaft with exit holes near a distal end of the shaft, a tool coupled to the distal end of the shaft, and a backend. The backend may include a mechanism that manipulates a drive element that extends through the shaft and couples to the tool, a fluid inlet, and a fluid channel assembly providing fluid communication between the fluid inlet and the proximal end of the shaft. Cleaning fluid is directed into the fluid inlet, through the fluid channel assembly, and into the shaft. A chassis or other structural piece of the backend may form part of the fluid channel assembly.

Abstract: A medical instrument includes a backend and a pair of release elements. The backend includes a docking feature shaped to engage a docking structure such as a docking port of a surgical robot or a sterile adaptor for a surgical robot. Each release element is coupled to the backend and may include an activation feature on one side of the backend and a push tab extending from either an opposite side or the same side of the backend. Movement of the activation features moves the push tabs from being aligned with the docking feature to pushing on the docking structure, permitting the medical instrument to be disengaged from the docking structure. Optionally, a coupling of the release elements limits a movement of the activation features.
