A treatment instrument output data analysis section includes a probe ID extraction section, an output waveform extraction section, a data analysis section and an analysis result output section. The analysis result output section of the treatment instrument output data analysis section can display on a centralized display panel a synthetic image made by synthesizing a frame image stored in an image storage section of an endoscopic camera apparatus and an analysis result analyzed by the data analysis section.

Operation system and method of notifying system operation information of same

According to the present invention, a heat generating element to be current-carried is provided at a grasp portion on the tip side of a treatment portion, the patient's body tissue grasped between a pair of grasp portions is coagulated by heat of the heat generating element, and a metal scissors blade for cutting the patient's body tissue is provided on the rear side of the grasp portion in the treatment portion.

Medical treatment instrument

The thermal treatment apparatus is equipped with a laser generator for supplying laser beams, a laser irradiation unit for applying the supplied laser beams to tissues, and a control unit for totally controlling various parts of the system. The laser irradiation unit is equipped with a movable laser emission part for emitting laser beams to tissues, a motor for reciprocating a laser emission part, and a guide lumen for supporting an endoscope in such a way as to enable it to move in the direction of the laser emission part. The control unit controls the motor that drives the laser emission part to make reciprocation motion in such a way that the laser emission part stops at a position where it does not interfere with the moving passage of the endoscope.

Thermal treatment apparatus

A thermal treatment apparatus comprises a control unit that stops issuing a signal for laser beam activation transmitted over the foot switch signal cable when the temperature obtained by the mirror temperature sensor that detects the temperature of the laser emission part provided at the laser irradiation unit exceeds a predetermined value. This stops the output of the laser beam from the laser generator Alternatively, the control unit can adjust the output value of the laser beam generated by the laser beam generator by transmitting a signal via the communication cable to change it in accordance with the detection signal of the mirror temperature sensor

A heat using therapeutic device includes an applicator provided with an insertion section, a balloon enclosing a high frequency warming electrode attached to the insertion section of the applicator; medicine ejecting holes arranged on the balloon; and a medicine passage for connecting the medicine ejecting holes to a medicine mouth piece attached to a rear end of the applicator.

Heat using therapeutic device

In a probe, two scintillators are arranged in tandem, the front end surfaces of two optical fibers transmitting the light emitted by the scintillators are connected to the rear of the scintillators and two photoelectric converters converting the light to pulse signals are connected to the rear of the optical fibers. A gate delay generator produces a gate signal from one pulse signal. A delay amplifier delays the other pulse signal. An M.C.A. will count up in case the pulse signal output by the delay amplifier is obtained during the gate signal.

Scintillation probe and intra-tube cavity insertable radioactive ray

A radioactive ray detecting endoscope comprises an elongated insertable part having an observing window in the tip part, an imaging apparatus converting an image of an observed part obtained through the observing window to an electric signal and a radioactive ray detecting apparatus detecting radioactive rays from inside the visual field of the imaging apparatus. The imaging apparatus has, for example, a solid state imaging device imaging an optical image of an object. Also, a collimator regulating the radioactive ray detecting direction is provided, for example, around the radioactive ray detecting apparatus.

Radioactive ray detecting endoscope

The radioactive ray detecting therapeutic apparatus of the present invention has an insertable part to be inserted toward an affected part. A therapeutic apparatus for treating the affected part, and a radioactive ray detecting apparatus for detecting radioactive rays discharged out of the affected part and providing signals by which to direct the therapeutic apparatus to the affected part, are provided in the tip part of the insertable part.

Radioactive ray detecting therapeutic apparatus

A radioactive ray detecting endoscope comprises an elongated insertable part, an ultrasonic imaging apparatus provided in the tip part of the insertable part for transmitting ultrasonic waves toward an observed part, for receiving echoes from the observed part by these ultrasonic waves, and for outputting a signal for forming an ultrasonic image and a radioactive ray detecting apparatus arrangeable in the tip part of the insertable part for detecting radioactive rays. Preferably, the observing direction of the ultrasonic imaging apparatus and the detecting direction of the radioactive ray detecting apparatus substantially coincide with each other.

This invention relates to new and useful 2,6-dimethyl-4-(pyrazolo[1,5-a]pyridin-3-yl)-1,4-dihydropyridine-3,5-dicar boxylate derivatives of the following formula: ##STR1## and pharmaceutically acceptable salts thereof, having potent promoting activity of some antitumor agents against various kinds of tumor cells including multiple drug resistant tumor cells.
