An apparatus comprising:
- a hub including a hub channel;
- a flexible conduit coupled to the hub;
- and
- a blade coupled to the conduit;
- wherein:
- (a)(i) the hub channel is coupled to a first portion of the conduit;
- and (a)(ii) the first portion of the conduit is hollow;
- wherein:
- (b)(i) in a first configuration the conduit and the hub couple to each other in a non-loop orientation;
- (b)(ii) in a second configuration the conduit and the hub couple to each other in a loop orientation, the loop orientation including a loop having a circumference;
- (b)(iii) in a third configuration the conduit and the hub couple to each other in an additional loop orientation, the additional loop orientation including an additional loop having an additional circumference;
- (b)(iv) the additional circumference is smaller than the circumference;
- wherein:
- (c)(i) the first portion of the conduit includes a first aperture, the first aperture to fluidly couple an external irrigation source to the conduit via the hub channel;
- (c)(ii) a second portion of the conduit includes at least one second aperture in a sidewall of the conduit;
- (c)(iii) the conduit includes a lumen that couples the first aperture to the at least one second aperture;
- (c)(iv) a third portion of the conduit is coupled to the blade;
- and (c)(v) the second portion of the conduit is between the first and third portions of the conduit;
- wherein:
- (d)(i) in the first configuration the first portion of the conduit couples to the hub and the third portion of the conduit does not directly contact the hub;
- (d)(ii) in both of the second and third configurations the third portion of the conduit directly contacts the hub;
- (d)(iii) the first, second, and third portions of the conduit collectively include the lumen;
- (d)(iv) the lumen is open in the first portion of the conduit;
- (d)(v) in each of the first, second, and third configurations the lumen is open in the third portion of the conduit;
- and (d)(vi) in a fourth configuration the hub seals the lumen and the lumen is closed in the third portion of the conduit.
