Atcus Series LASER
Devices for Medicine

ATC-Semiconductor Devices presents recently developed ATCUS series laser devices. Each device consists of the optical block, electronic control block, optical instrument and foot pedal.
Optical block is the optical-mechanical unit consisting of a few laser diodes with focusing objectives, optical socket, Peltier-element with thermistor.
Electronic control block controls the operation modes of the optical block. Electronic control block includes a few control channels (for each laser diode).

Control channel consists of three functional parts:

• Temperature stabilizer based on the Peltier-element;

• Control over the laser diode current;

• Protection for the laser diode.

Optical instrument delivers optical radiation.
Foot pedal allows remote switching the laser on and off.

The basic advantages

• Mobility

• Opportunity of influence on deeply located tissues;

• High accuracy and selectivity of influence;

• Absence of water and air external cooling;

• Simplicity of service and use, readiness to work practically right after turning on;

• Source of radiation is semiconductor laser diodes having high reliability and the large resource;

• Each laser diode mounted on separate Peltier element;

• Warranty service of 12 months.

Laser technologies can play a main role in treatment of the oncological diseases of various localisation. The most effective are the photodynamic therapy (FDT), the selective laser hypårthermia (SLH), and also a combination of these methods.

For realisation of these methods laser devices " Atcus-2 " (FDT with use of the newest domestic photosensibilizer of the second generation - Fotoditazin), " Atcus -15" (SLH) and " Atcus -10" (combination of FDT and SLH) are created. The photosensibilizer Fotoditazin prodused by firm Veta-Grand.

In some cases, when the traditional methods of treatment are not applicable due to certain reasons, the laser treatment could be the only way.

Clinical testing of the semiconductor laser device "Atcus-15" were held in the St.-Petersburg Scientific research institute for oncology named after N.N. Petrov of the Ministry of Health of the Russian Federation. Basing on their results the patents of the Russian Federation (¹ 2122452, ¹ 2134603) for treatment of neoplasms with the selective laser hypårthermia method were received.

Since 1998 the medical laser devices of "Atcus" series are intensively used in leading medical centres of Russia for development of the treatment methods for various diseases:

• State scientific centre for laser medicine of the Ministry of Health of the Russian Federation (Moscow), (organs of a belly cavity, urinogenital system and anarektaly zones);

• St.-Petersburg State Medical Academy named after I.I.Mechnikov (endoscopic surgery);

• Medical Radiological Research Centre of the Russian Academy of Medical Sciences, (Obninsk) (oncology);

• St.-Petersburg Scientific research institute for oncology named after N.N. Petrov (oncology);

• St.-Petersburg Medical University named after Academician I.P.Pavlov (otolaryngology).

Main advantages of Atcus-15 are high accuracy and precise control during the operation, smaller post-operative edema, considerable decrease of bleeding and pain, simplicity of service and usage of the laser, and finally, its low price, which increases economic efficiency of the laser cabinet. External air- or water-cooling is not required for operation of the laser.
