1. A tip apparatus for a reusable laser surgical device, the tip apparatus comprising: a) a disposable tip housing with a first end having a longitudinal axis and adapted to releasably fit on the distal end of the surgical device;b) an optical fiber for delivery of light energy axially positioned within the tip housing and extending beyond the tip housing;c) means for releasably locking the tip housing first end to the surgical device; andd) a laser housing assembly that receives the first end of the tip housing, wherein the laser housing assembly includes a channel that is sized to receive the tip housing first end along the longitudinal axis, and a conductive wire sensor having two ends positioned transverse to the tip housing longitudinal axis, whereby the conductive wire sensor contacts the tip housing first end when it is properly positioned within the channel, and wherein contact between the conductive wire sensor and the tip housing first end closes an electrical circuit. 2. The tip apparatus of claim 1, wherein the conductive wire sensor is housed within the laser housing assembly by insulated tubing. 3. The tip apparatus of claim 1, wherein the wire sensor comprises gold plated steel. 4. The tip apparatus of claim 1, wherein the laser housing assembly includes an emitter element and a detector element positioned on either side of the channel, whereby the emitter and detector elements can detect whether the tip housing first end is positioned in the channel. 5. The tip apparatus of claim 1, wherein the means for releasably locking the first end to the surgical device comprises at least one member of the group consisting of means for magnetic coupling, means for mechanical coupling, means for electro-mechanical coupling, and means for electro-magnetic coupling. 6. The tip apparatus of claim 1, wherein the tip housing is made of at least one member of the group consisting of polyimide, polycarbon, stainless steel, steel, iron, plastic, and aluminum. 7. The tip apparatus of claim 1 packaged as a sterile assembly.
