Abstract: A hand held myringotomy instrument comprises an otoscope and an attached laser beam generator section. The laser beam generator section comprises a portion for moving the laser beam generator of the section along the laser beam axis, in order to adjust the position of the focus of the laser beam nearer, or father from the instrument. Preferably, the moving portion includes an inner sleeve carrying the generator and an outer sleeve respectively inside and outside of a tube connected to the otoscope. A pair of elements diametrically opposed attached to the inner tube project through longitudinal slots diametrically opposed in the tube and are externally threaded to mesh with internal threads on the outer sleeve. The slots restrict the motion of the elements to axial motion. Collars restrict the motion of the outer sleeve to rotational motion. Thus, rotation of the outer sleeve causes longitudinal motion of the elements which moves the laser beam lens system carried by the inner sleeve axially along the laser beam axis as desired.

Abstract: An endoscopic laser instrument is adapted to treat selected areas of body tissue, such as the treatment and evaporation of tumors occurring on the inner of a bladder. The instrument comprises an outer tubular sheath having an optical fiber extending therethrough to emit a laser beam onto an adjustable mirror that reflects the laser beam exiting the fiber to selected areas of the bladder without changing the character of divergence of the beam once it has emerged from the fiber. A standard endoscope viewing optic is mounted in the sheath to permit a surgeon to visually inspect the bladder through a wide visual field. A gas, such as carbon dioxide, is continuously circulated through the instrument and into the bladder for inflation and purging purposes.

Abstract: Laser irradiating apparatus equipped with a vertical shaft fixed on a power supply box, a first arm which slides up and down along the shaft and rotates around the shaft and a second arm which is pivoted at the first arm tip portion, and with a laser head installed on the second arm. In this apparatus, an articulated arm light guide is fixed on the upper side of the laser head tip portion. Variation of positions of the first and second arms provides a wide range for operation and much compactness of the apparatus when storing. In addition, the laser head is soundly installed on the second arm upper surface, which is useful to prevent any optical deviation.

Abstract: A laser device particularly suitable for use in surgery includes a housing and a laser beam oscillation device elastically mounted within the housing. The laser beam oscillation device includes an elongated support stand which extends substantially vertically within the housing and through an opening in the top of the housing, and a laser beam resonator such as a CO.sub.2 laser is mounted on the support stand to provide a laser beam having an optical axis. A laser beam transmitting arrangement is connected to the support stand coaxially with the optical axis of the laser beam. As a result of this construction, the laser device occupies significantly less floor area within an operating room, and can easily be moved about while maintaining optical alignment at all times.

Abstract: A wavebeam guide transmitting the laser emission to a selected region of a patient comprises only two mirrors; an input mirror and a output mirror, which mirrors are mounted in units of the device connected by a telescopic shaft. The input mirror is mounted so that it can rotate about an axis coinciding with the axis of the laser beam falling thereupon and about an axis perpendicular thereto. The output mirror can also rotate about the axis of the laser beam falling thereon and about the perpendicular axis. Both mirrors can also rotate together in relation to the axes of rotation of the input mirror and the distance between the mirrors can be changed by means of the telescopic shaft. An aiming grip is provided to carry a focusing lens mounted so that it can rotate about the axis of the laser beam reflected by the output mirror.

Abstract: A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue.
