A laser probe including an optical fiber for guiding a laser beam, a holder fixed at an end portion of the optical fiber, and a reflection tip detachably attached to the holder and having a reflection surface for reflecting the laser beam emitted from the optical fiber.

Laser probe

A fluorescent endoscope apparatus having: an endoscope that irradiates a subject portion to be observed with light transmitted through a light transmission device to obtain an object image of the subject portion to be observed; a normal observation light generating device for emitting normal light for performing normal light endoscope observation; a fluorescent observation light generating device for emitting excitation light for performing fluorescent light observation; an introduced-light switching device for selectively introducing, to the light transmission device of the endoscope, normal light emitted by the normal observation light generating device or excitation light emitted by the fluorescent observation light generating device; and an image sensing device for capturing a normal light image of the subject portion to be observed that can be obtained by irradiating the subject portion to be observed with normal light or excitation light or a fluorescent image that can be obtained due to irradiation with excitation light, the image sensing device being included or connected to the endoscope.

Fluorescent endoscope apparatus

An apparatus for holding a medical instrument, such as an endoscope, in place without exerting an undue force on an insertion hole in an abdominal cavity of a subject even when the arm of a scope-holding section is unlocked, includes a four-link parallelogram mechanism. The four-link parallelogram mechanism includes a support arm for supporting a treating tool, an arm section parallel to the support arm and upper and lower arm sections connected to the upper and lower end sides of the support arm and arm section in a parallel relation. A support mechanism supports the arm sections of the four-link parallelogram mechanism to allow the arm sections to be moved in left/right and up/down directions, while being rotated, so that a straight line connecting an intersecting point P of a center line of the treating instrument inserted into an insertion hole in an abdominal wall of a subject and the center of the insertion hole to spherical bearings of the arm is set parallel to the upper and lower arm sections.

Apparatus for holding a medical instrument in place

A laser beam irradiation apparatus comprising a laser generating device, a laser beam irradiation probe for applying a laser beam from the laser generating device to a region of an object of irradiation, an ultrasonic transmitter/receiver for emitting ultrasonic waves toward the region to which the laser beam is applied by the probe, receiving reflected waves from the irradiated region, and converting the reflected waves into an electrical signal, a measuring device for measuring the temperature of the irradiated region in accordance with the electrical signal from the ultrasonic transmitter/receiver, and an output adjuster for adjusting the output of the laser generating device in accordance with a temperature signal from the measuring device.
