Abstract: Systems and subsystems for cutting and stapling tissue are disclosed. More specifically, the present disclosure relates to systems, devices, and subsystems for attachments for robotic surgeries. The surgical instrument is a robotic attachment including a roll subsystem. The roll subsystem comprises a rotatable shaft having a longitudinal axis, a roll input puck engageable with a roll robotic output, a worm gear coupled to and rotatable by the roll input puck, and a worm follower coupled to the rotatable shaft. Rotation of the roll input puck causes the worm gear to rotate the worm follower and thereby roll the rotatable shaft about its longitudinal axis.

Abstract: Systems and subsystems for cutting and stapling tissue are disclosed. More specifically, the present disclosure relates to systems, devices, and subsystems for attachments for robotic surgeries. The surgical instrument includes a transection subsystem comprising a rotatable shaft having a lumen, a firing rod extending at least partially through the lumen, a firing rack coupled to a proximal end of the firing rod, the firing rod being rotationally independent of the firing rack, and a firing gear engaged with the firing rack. Rotation of the firing gear moves the firing rack and the firing rod axially.

Abstract: A cutaneous catheter anchoring device and method to prevent occlusion of an indwelling peripheral intravenous catheter and to do so in a way that does not require immobilization of, or significant reduction in the range of motion of, the joint of the particular extremity. The device and method accomplish this by immobilizing multiple areas of the skin's surface relative to the indwelling catheter. The device is in close proximity to the indwelling catheter and maintains a smooth, rather than bent or creased, skin surface above the catheter thus preventing creasing or kinking of the catheter itself during times when the patient bends the extremity.
