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. ## Claims ### Claim 1 1) A blade assembly comprising: a. a tip including two or more tubes, wherein the two or more tubes include at least: i. an outer tube and ii. an inner tube; and b. a mechanical enclosure including: i. a locking spline having a longitudinal axis; and ii. 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. ### Claim 2 (depends on 1) 2) The blade assembly of claim 1, wherein the slide lock includes an actuation connection that connects the slide lock to a lock lever. ### Claim 3 (depends on 1) 3) The blade assembly of claim 1, wherein the mechanical enclosure includes a control enclosure and a connection enclosure that at least partially cover the slide lock. ### Claim 4 (depends on 3) 4) The blade assembly of claim 3, wherein the lock lever extends through the connection enclosure so that the lock lever is exposed for actuation by a user. ### Claim 5 (depends on 1) 5) The blade assembly of claim 1, 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. ### Claim 6 (depends on 1) 6) 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. ### Claim 7 (depends on 1) 7) 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. ### Claim 8 (depends on 7) 8) The blade assembly of claim 7, wherein the slide lock includes one or more teeth that correspond with the one or more ribs of the locking spline so that when the slide lock slides over the locking spline in a 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. ### Claim 9 (depends on 6) 9) The blade assembly of claim 6, 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. ### Claim 10 (depends on 1) 10) The blade assembly of claim 1, wherein the slide lock is housed in an collet, and the collet extends into a handpiece and assists in connecting the blade assembly to the handpiece. ### Claim 11 (depends on 10) 11) The blade assembly of claim 10, wherein the collet is fixed to the handpiece so that the collet is free of rotational movement, lateral movement, longitudinal movement, or a combination thereof. ### Claim 12 (depends on 1) 12) The blade assembly of claim 1, wherein the at least two tubes of the tip are three tubes, and the outer tube is a rigid sheath that forms a bend so that an intermediate tube and an inner tube located within the outer tube are bent at an angle. ### Claim 13 13) A blade assembly comprising: a. a tip including three or more tubes, wherein the three or more tubes include at least: i. an outer tube; ii. an inner tube; and iii. an intermediate tube located at least partially between the inner tube and the outer tube; and b. a mechanical enclosure including: i. a nosecone having a nosepiece gear; and ii. a collet having one or more pinion gears that are in communication with the nosepiece gear; wherein the intermediate tube is connected to an outer hub that extends though the collet, the outer hub including a toothed portion that is in communication with the one or more pinion gears so that rotation of the nosecone causes rotation of the intermediate tube. ### Claim 14 (depends on 13) 14) The blade assembly of any of claim 13, wherein the one or more pinion gears are two pinion gears so that the intermediate tube rotates in the same direction as the nosecone. ### Claim 15 (depends on 13) 15) The blade assembly of claim 13, wherein the intermediate tube includes a window that exposes at least a portion of the inner tube, and wherein the inner tube rotates independently of the intermediate tube, the outer tube, or both. ### Claim 16 (depends on 13) 16) The blade assembly of claim 13, wherein the nosecone and the nosepiece gear are two pieces or the nosepiece gear is integrally formed in the nosecone. ### Claim 17 17) A blade assembly comprising: a. a tip including two or more tubes, wherein the two or more tubes include at least: i. an outer tube; ii. an inner tube; and b. a mechanical enclosure including: nosecone having a rotational axis; wherein the outer tube is connected to the nosecone so that rotation of the nosecone causes rotation of the outer tube. ### Claim 18 (depends on 17) 18) The blade assembly of claim 17, wherein the outer tube includes a window that exposes at least a portion of the inner tube, and wherein the outer tube can be rotated independently of the inner tube and vice versa. ### Claim 19 (depends on 17) 19) The blade assembly of claim 17, wherein the two or more tubes include: a. the outer tube; b. an intermediate tube located at least partially within the outer tube; and c. the inner tube located at least partially within the intermediate tube. ### Claim 20 (depends on 17) 20) The blade assembly of claim 17, wherein the outer tube is a rigid bend producing sheath that bends at least a portion of the intermediate tube and the inner tube.
