Replacable debrider blade module with latching mechanism

A blade assembly comprising:

• a. a tip including two or more tubes, wherein the two or more tubes include at least:
• iii. an outer tube and
• iv. an inner tube;
• and
• b. a mechanical enclosure including:
• v. a locking spline having a longitudinal axis;
• and
• vi. a slide lock that is movable between a locked position and an unlocked position within the mechanical enclosure;
• wherein the slide lock moves between the locked position and the unlocked position along a longitudinal axis of the locking spline, and the slide lock in the locked position extends over the locking spline forming a locked state so that rotational movement of the locking spline, around the longitudinal axis of the locking spline, is prevented;
• and
• wherein the outer tube is coupled to the locking spline so that rotational movement of the outer tube, around the longitudinal axis of the locking spline, is prevented during the locked state;
• wherein a biasing member is located between the slide lock and the locking spline so that the biasing member assists in moving the slide lock off of the locking spline forming an unlocked state when the locking spline is in the unlocked position.
