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 force transmission mechanism for a surgical instrument includes a worm drive, a lever arm, and an actuation element. The lever arm may include a follower member at a first end of the lever arm. The follower member engages the worm drive and is configured to be driven by the worm drive. The actuation element is connected the lever arm. The actuation element is configured to transmit force to actuate an end effector of the surgical instrument. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm.

Abstract: A surgical instrument may comprise a chassis, a shaft coupled to the chassis at the proximal end of the shaft, an end effector coupled to the shaft at the distal end of the shaft, a force transmission mechanism coupled to the chassis, and an actuation element connected between a lever arm of the force transmission mechanism and the end effector. The force transmission mechanism includes a worm drive, and the lever arm comprising a first end and a follower member at the first end of the lever arm, wherein the follower member is engaged with the worm drive and is configured to be driven by the worm drive. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm, and the lever arm slides along a generally linear direction relative to the chassis to impart the translational movement to the actuation element.

Abstract: A cannula seal is presented. The cannula seal includes a cross-slit seal that can include a side wall that includes folded sidewalls; slits that are formed by the folded sidewalls when the cross-slit seal is in a closed position; and a concave end surface at the slits. The cross-slit seal can include energizing ribs formed to close the seal. The instrument guide includes a pyramidal shaped seal that seals against doors when no instrument is inserted and seals against an instrument when the instrument is inserted.

Abstract: An actuation mechanism for a medical instrument includes a pinion and a face gear that move a push-pull element. The pinion has a mounting that permits rotation of the pinion by an external control system such as a robot. The face gear meshes with the pinion. The push-pull element may have a proximal end coupled to the face gear and a distal end coupled to a tool at a distal end of an instrument shaft. A manipulator coupled for manual rotation of the actuation mechanism may include a slip clutch to prevent manual application of excessive force to the actuation mechanism.
