Abstract A microsurgical laser device for guiding a laser beam to a desired target. The device includes a laser head that is vertically oriented and which is supported by a base that contains the required electronics for the system. This laser head can be tilted in all directions so as to position the device for use. The laser head is coupled to an articulated delivery system that allows for the delivery system, including a colposcope or an operating microscope, to be raised, lowered, tilted, rotated, and focused onto the target. The articulated connection from the laser head to the colposcope or operating microscope makes use of a minimum number of mirrors to redirect the laser beam at 90 degree angles along a direction perpendicular to the axis of the incident path. Each mirror is mounted on precision mounts that obviate the need for adjustments. In one embodiment of the device the articulated system makes use of three mirrors to redirect the beam and one lens to provide a fixed laser spot size at the target. In another embodiment of the device, four mirrors are used and two lenses are employed in order to provide a variable laser spot size at the target.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A self-contained surgical laser system for delivering laser energy to selected target sites to vaporize tissue such as in gynecological applications which comprises: (a) a generally vertical column housing a CO 2 laser for emitting a first laser beam, a second laser of the type emitting a laser beam visible to the unaided human eye and means for optically aligning said laser beams; (b) a stable movable base member pivotally anchoring said column, said base member including means for permitting said column to be universally pivoted relative to an axis intersecting said base member; (c) a hollow telescopic support member supported by said column and positioned for transmitting said laser beams therethrough; (d) means connected to said telescopic member for tilting said column relative to the location of the desired target site; and (e) viewing means supported by said telescopic support member for aiming, microscopically viewing and delivering said laser beams from said support member to a desired target site without moving either said vertical column or said base member.
Claim 2
Dependent Claim
