The delivery system includes a handpiece adapted for rotatable coupling to a delivery arm coupled to the laser energy source such that the handpiece is rotatable about its longitudinal axis with respect to the delivery arm. A distal delivery system is coupled to the handpiece and delivers laser energy to the surgical site when the laser energy source is actuated. The handpiece includes a handpiece body adapted for rotatable coupling to the delivery arm and a handpiece head coupled to both the handpiece body and the distal delivery system. The handpiece head can be rotatably coupled to the handpiece body. In one embodiment, the handpiece head is angularly oriented at a fixed angle with respect to the handpiece body. In an alternative embodiment, the handpiece head is pivotally coupled to the body such that the handpiece head may be adjusted to various angles with respect to the handpiece body, such pivotal coupling preferably being accomplished by a ball and socket joint. A removable fiber extension is positioned within the handpiece and transmits laser energy from a fiber in the delivery arm to the distal delivery system. The distal delivery system includes an interchangeable delivery tip through which the laser energy is delivered to the surgical site. The tip can be a solid or hollow fiber of various sizes and shapes. ## Claims ### Claim 1 A medical laser delivery system usable in conjunction with a laser energy source and a delivery arm coupled to the laser energy source to transmit laser energy, comprising: a handpiece adapted for rotatable coupling to the delivery arm, the handpiece including transmission means for transmitting the laser energy received from the delivery arm, the handpiece being rotatable about its longitudinal axis;
