Abstract
The systems, methods, and apparatus disclosed herein are directed to an exchangeable working channel for a surgical instrument comprising a proximal portion, a distal portion, and an instrument channel configured to receive the exchangeable working channel. The exchangeable working channel may comprise a shaft comprising a proximal region and a distal region; an inner surface defining a lumen extending through the shaft; and an outer surface configured to interface with the instrument channel of the surgical instrument. The exchangeable working channel may further comprise one or more locking members configured to releasably couple to the proximal portion or the distal portion of the surgical instrument. The exchangeable working channel may increase a service life of the surgical instrument as a worn working channel can be exchanged with a new one.
