1. A device, comprising:
- a handle housing having a distal end and a proximal end, an inner surface of the handle housing defining a first portion of a waveguide conduit;
a waveguide lock housing having a distal end and a proximal end, the distal end of the waveguide lock housing operably secured to the proximal end of the handle housing;
a collet positioned at least partially within the waveguide lock housing;
a push button positioned at least partially within the waveguide lock housing and connected to the collet, inner surfaces of the push button and the collet defining a second portion of the waveguide conduit; and
a spring positioned within the waveguide lock housing that biases the push button and the collet in a proximal direction relative to the distal end of the waveguide lock housing.

Abstract
An optical radiation delivery structure including a waveguide conduit having a surgical access portion and a handle portion. The handle portion includes a gripping portion and a waveguide lock, which is configured to have only a locked state and an unlocked state. In some embodiments, the handle portion includes a gripping portion and a counterbalance region, such that a center of mass of the waveguide conduit is disposed towards a proximal end of the waveguide conduit.

12. 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. - View Dependent Claims (13, 14)

15. 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. - View Dependent Claims (16, 17, 18, 19)
