EXCHANGEABLE WORKING CHANNEL
First Claim
1. A removable working channel of a surgical instrument, the surgical instrument having a proximal portion, a distal portion, and a working channel sheath configured to receive the removable working channel, the removable working channel comprising:
- 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 working channel sheath of the surgical instrument; and
a first locking member at the proximal region of the shaft, the first locking member configured to releasably couple to the proximal portion of the surgical instrument.

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.

16. A surgical instrument configured to receive a removable working channel, the surgical instrument comprising:
-
a proximal portion and a distal portion; an instrument channel extending through the proximal and distal portions, the instrument channel comprising; a proximal region and a distal region; and an inner surface defining a lumen extending through the instrument channel; a working channel sheath attached to the inner surface of the instrument channel and configured to interface with the removable working channel; and a first coupling member at the proximal portion of the surgical instrument, the first coupling member configured to releasably couple to a proximal region of the removable working channel. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A tool configured to adjust an attachment between a removable working channel and a surgical instrument, the removable working channel having proximal and distal regions, the surgical instrument having proximal and distal portions, the tool comprising:
-
an actuator configured to engage and actuate at least one of (i) one or more locking members at the proximal region of the removable working channel and (ii) one or more coupling members at the proximal portion of the surgical instrument, wherein, in use, the engagement and actuation of the at least one of (i) one or more locking members and (ii) one or more coupling members by the actuator facilitates at least one of locking and unlocking the attachment between the removable working channel and the surgical instrument.

24. A method for sanitizing one or more removable working channels of a surgical instrument, the method comprising:
-
removing a first removable working channel from the surgical instrument; analyzing an integrity of the first removable working channel; cleaning and reinstalling the first removable working channel in an instrument channel of the surgical instrument in response to the integrity of the first removable working channel being uncompromised; and replacing the first removable working channel with a second removable working channel in the instrument channel in response to the integrity of the first removable working channel being compromised. - View Dependent Claims (25, 26, 27, 28, 29, 30)
