Waveguide locks and counterbalances for waveguide conduits

A method, comprising:

• selecting a laser radiation delivery device including a surgical access portion, a handle portion and a waveguide conduit that extends through the surgical access portion and the handle portion, the handle portion having a gripping portion and a waveguide lock, wherein the waveguide lock is operable in a locked state and an unlocked state;
• pressing a spring-biased push button positioned at a proximal end of the handle portion in a distal direction to place the waveguide lock in the unlocked state;
• inserting a waveguide into the waveguide conduit while the waveguide lock is in the unlocked state;
• and
• releasing the push button to place the waveguide lock in the locked state in which the waveguide lock fixedly holds the waveguide in a selected axial position relative to the waveguide conduit.

A method, comprising:

• positioning a collet at least partially within a waveguide lock housing having a distal end and a proximal end, a portion of the collet extending through the distal end of the waveguide lock housing;
• positioning a spring within the waveguide lock housing between the distal end and the proximal end of the waveguide lock housing;
• positioning a push button at least partially within the waveguide lock housing, the spring being between the push button and the distal end of the waveguide lock housing;
• physically coupling the push button to the collet, the spring biases the push button and the collet in a proximal direction relative to the distal end of the waveguide lock housing;
• and
• physically coupling the distal end of the waveguide lock housing to a proximal end of a handle housing,
• wherein an inner surface of the handle housing defines a first portion of a waveguide conduit, and inner surfaces of the push button and the collet define a second portion of the waveguide conduit.
