摘要:
A positioning system for an applicator includes a glove for being used for a diagnosis of the affected part, a mark body provided on the glove, an applicator for being inserted into a living body, and an energy emitter provided on the applicator for supplying energy to the living body. The positioning system further includes a sensor provided on the applicator which is capable of detecting the distance to the mark body, a control apparatus for discriminating an optimum position of the applicator based on the distance between the sensor and the mark body while the mark body is disposed in the proximity of the affected part based on a diagnosis performed using the glove, and a display apparatus for displaying a result of the discrimination by the control apparatus.
摘要:
A temperature measuring unit of a temperature sensor has electrodes disposed on the upper and lower surfaces of a temperature measuring element, thin-film substrates disposed on the upper and lower surfaces of the electrodes, and laser beam shield plates disposed on the upper and lower surfaces of the thin-film substrates. One of the electrodes is bonded to the temperature measuring element by a conductive adhesive, and the other electrode is not bonded to the temperature measuring element by a conductive adhesive. When the temperature sensor is bonded to a hollow cylinder of an insert, the temperature measuring unit is curved along the surface of the hollow cylinder, tending to develop tensile stresses in the other electrode. At this time, the other electrode is positionally displaced depending on the developed tensile stresses, allowing the temperature sensor to be adjusted in length. Consequently, the temperature sensor is prevented from being broken or damaged.

A thermal treatment apparatus comprises a control unit 251a that stops issuing a signal for laser beam activation transmitted over the foot switch signal cable 291 when the temperature obtained by the mirror temperature sensor 111 that detects the temperature of the laser emission part 122 provided at the laser irradiation unit 1 exceeds a predetermined value. This stops the output of the laser beam from the laser generator 3. Alternatively, the control unit can adjust the output value of the laser beam generated by the laser beam generator 3 by transmitting a signal via the communication cable 293 to change it in accordance with the detection signal of the mirror temperature sensor 111.
摘要:
In a thermal therapy apparatus for treating a vital tissue by irradiating the tissue with a laser beam, a display unit displays a figure indicating the shape of a diseased part to be heated on the basis of information concerning the diseased part. Heating regions are arranged in the displayed figure indicating the diseased part shape by using identifiers corresponding to individual heating conditions. In accordance with size/position information of these heating regions arranged, heating conditions such as the laser intensity laser irradiation time and laser irradiation angle are set. Laser beam irradiation is performed by controlling the irradiation in accordance with the set heating conditions. The information pertaining to the diseased part can also be input on the basis of an ultrasonic signal from an ultrasonic probe separated from or installed in the laser irradiation portion.
摘要:
An energy irradiation apparatus for medical treatment of tissues through irradiation of energy including a long main unit, an emitting part, a power transmission member, a drive mechanism, a first engaging member, and a second engaging is disclosed. The emitting part is disposed moveably inside a distal end of the main unit for emitting energy transmitted to a distal side from a proximal side. The power transmission member is disposed moveable inside the main unit. The emitting part is mounted to a distal end of the power transmission member. The drive mechanism reciprocates the power transmission member in a longitudinal direction of the main unit. The first engaging member is provided inside the power transmission member for receiving a drive force from the drive mechanism. The second engaging member is provided in the drive mechanism for engaging removably with the first engaging member.
摘要:
To provide a medical energy irradiation apparatus which permits easy and accurate establishment of a site of tissues of a living body targeted for irradiation with energy, when doctors use the medical energy irradiation apparatus to perform a cure for a prostatic hyperplasia or the like. The doctors insert an applicator 110 of the medical energy irradiation apparatus to an urinary bladder 161 and fix an endoscope 135 near to an entrance of an urethra. In this arrangement, when observing with the endoscope (135), a seminal colliculas 144 observed through a side-observation window 130 is observed toward a lower part of an observed image (schematic diagram) displayed on a display unit, and a positioning marker 140 in an interior of the applicator is observed toward an upper part of an observed image. The doctors can accurately determine a position to be irradiated with laser light from positions of the seminal colliculas 144 and the positioning marker 140 observed, and a direction of irradiation with laser light from a position of a direction marker 142, respectively.

To provide a medical energy irradiation apparatus which, having a simple and inexpensively manufacturable structure, enables a doctor using it in the heat curing of prostatic hypertrophy or the like to accurately and stably irradiate a prescribed site deep in a living body with a laser beam and, even if its observation window is smeared, to observe tissues of a living body. An inserting portion of the medical energy irradiation apparatus to be inserted into a living body according to the invention has an emitting portion for emitting a laser beam toward tissues of the living body; an observation window, provided near the tip of the inserting portion in its inserting direction, for observing the tissues of the living body; and a hollow pipe for supporting a supporting member, which supports the emitting portion, shiftably in the lengthwise directions of the inserting portion and feeding detergent to the observation window. Therefore, when the observation window is smeared, detergent can be fed to the observation window to remove the smear of the observation window.

To provide efficient table partitioning, a database is described for distributively locating a plurality of sub-tables resulting from partitioning of a table in a database. This includes an acquiring section that monitors access occurrences to each of the sub-tables to acquire a history of access occurrences. Also a deciding section decides a table storage area in which a sub-table is to be located, based on the history of access occurrences to each of the sub-tables.
