ABSTRACT:
A handpiece for use with laser surgical contact scalpels having a housing or handle portion with a laser enabling button thereon whereby a surgeon may expeditiously cycle the laser between its on and off conditions. The handpiece further including a mechanism for facilitating the longitudinal and rotational adjustment of the surgical scalpel with respect to the handle whereby optical fiber torque may be relieved and whereby the surgical tip may be oriented properly with respect to the laser actuation button. The adjustment mechanism includes torsional and longitudinal travel limits to protect button interconnect wires and means for locking the mechanism thereby to fix the relative positions of the scalpel and handle. The laser enabling button and associated circuitry including a low voltage self-contained power source and, further, optical isolation from the laser source whereby the laser may be cycled by the surgeon through use of the handpiece button without danger of electrical shock to the patient.
