Abstract: A laser apparatus for medical treatment use in which a laser beam is irradiated on a portion of a human body to be treated comprises a laser beam generation unit for generating a laser beam of giant pulse, a laser beam guide member having one end through which the laser beam from the laser beam generation unit is guided, and a hand piece attached to another end of the laser beam guide member and irradiating the laser beam to the portion to be treated. A beam converging point is formed within a laser beam propagating path formed in at least one of the light guiding means and the hand piece and a stay of air is prevented from a predetermined region in the laser beam propagating path including at least the beam converging point at which the air stays. The predetermined region is positioned within the hand piece or the laser beam guide member. The air stay is prevented by means of producing a vacuum state, gas seal state or air flow state in the predetermined region.

Abstract: A method and apparatus for laser-assisted hair transplantation preferably utilizes a CW mode CO.sub.2 laser, which may already have been installed in a surgeon's office, and a flashscanner to scan the laser over the area of holes to be drilled, thereby minimizing thermal necrosis on the recipient walls or slits. Optionally, a computer controls the laser/flashscanner assembly to redirect the beam from hole to hole, so as to rapidly drill a plurality of uniformly spaced holes. Advantageously, the time duration of the laser procedure is not limited, but depends instead on the CW laser power level parameters and the focal length selected for the procedure, thereby affording the surgeon significant flexibility in choosing appropriate treatment parameters.

Abstract: A hair transplant procedure is described which includes preparing a plurality of hair plugs from a donor site on the scalp. A corresponding number of incisions are drilled into the hairless recipient site using a pulsed laser beam. Preferably, the beam is generated from a high power, RF excited, carbon dioxide, slab waveguide laser. The pulse characteristics of the laser are chosen to ablate the tissue to the desired depth while minimizing bleeding. The plugs are inserted into the incision and hair growth in the recipient region is promoted.

Abstract: A laser surgical instrument is disclosed comprising a laser element mounted in a first hollow tubular member with a tapered open tip for insertion into a surgical site and having an opening at one for connection by a hollow tubing to a source of a purge gas for keeping the laser focusing lens free from smoke. A second tubular member fits on the first tubular member and extends substantially to the first tubular element tapered end. The second tubular member has a side opening for connection to a source of vacuum. A sleeve is slidably mounted on the second tubular member and is movable between a retracted position exposing the tip of the first tubular member and an extended position extending into the surgical site to provide a hood for withdrawal of smoke. The movement of the sleeve between retracted and extended positions provides for selected application of vacuum to the surgical site.

Abstract: The present invention is a gas insufflation apparatus which is used with an arthroscopic attachment having a gas inlet. A cylinder contains gas at a high pressure. A single stage regulator is fluidly coupled to the cylinder in order to regulate the inlet pressure of the gas. The gas insufflation apparatus includes a filter, an inlet relief valve and an inlet pressure gauge. The filter is fluidly coupled to the single stage regulator. The inlet relief valve insures that the inlet pressure of the gas does not exceed a predetermined pressure. The inlet pressure gauge reads the inlet pressure. The gas insufflation apparatus also includes a control valve and a flow meter. The control valve turns the flow of the gas through the gas insufflation apparatus on and off. The flow meter measures the flow of the gas through the gas insufflation apparatus. The gas insufflation apparatus further includes a first regulator and a second regulator. The first regulator insufflates the gas directly into the knee joint at a first preselected pressure in order to distend the knee joint during arthroscopic surgery. The second regulator insufflates the gas directly into the arthroscopic attachment through the gas inlet at a second preselected pressure which is slightly higher than the first preselected pressure in order to distend the knee joint and provide positive gas flow through the arthroscopic attachment during arthroscopic surgery by the laser system.
