Replacable debrider blade module with latching mechanism
A blade assembly comprising: a tip including two or more tubes, wherein the two or more tubes include at least: an outer tube and an inner tube; and a mechanical enclosure including: a locking spline having a longitudinal axis; and a slide lock; wherein the slide lock slides along the longitudinal axis of the locking spline and 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.
1. 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.
2. The blade assembly of claim 1 , wherein at least one of the two or more tubes extend through the slide lock, and wherein the outer tube includes slots.
3. The blade assembly of claim 1 , wherein the locking spline includes one or more ribs, and wherein the slide lock includes one or more teeth, and wherein the one or more ribs are tapered at one end.
4. The blade assembly of claim 3 , wherein the one or more teeth correspond with the one or more ribs of the locking spline so that when the slide lock slides over the locking spline in the locked state the one or more ribs and the one or more teeth form a fixed connection and prevent rotation of the outer tube, the locking spline, or both.
5. The blade assembly of claim 2 , wherein the locking spline includes tabs that correspond to the slots in the outer tube so that the outer tube and the locking spline form a fixed connection.
