Resumen:
Una empresa rusa está desarrollando un instrumento quirúrgico de la próxima generación que consiste en un sistema de dos láseres. Sus parámetros técnicos permiten realizar operaciones quirúrgicas sin sangre en tejidos blandos, huesos y cartílagos, sin señales de daño térmico. El aspecto innovador es el impacto simultáneo de la energía de radiación de dos láseres en los biotejidos, lo que permite la incisión eficaz sin sangre o la evaporación de tejido patológico sin daño térmico. La empresa busca fabricantes de equipos médicos avanzados con el fin de establecer acuerdos de cooperación técnica y joint venture.

Tittle:
Laser system for less traumatic surgery
Summary:
Small Russian innovative company is developing the surgical instrument of next generation that is two-wave laser system, which technical parameters make possible to perform bloodless surgical operations on soft, bone and cartilage without signs of their thermal damage.
The company is looking for partners for technical cooperation and joint venture agreements.

Description:
Intraoperative bleeding is one of the most dangerous complications in surgical practice, sometimes it leads to death in a short time. In order to achieve intraoperative hemostasis electrosurgical instruments, ultrasonic, plasma and laser scalpels are used now in surgery. Despite apparent diversity of tools, there is one principle of bleeding stop which is thermal coagulation of biofabrics. Thermal coagulation of biofabrics is the process of denaturation of the protein molecules, deferred or immediate tissue necrosis. The use of lasers in surgery is based on the effect of the absorption of laser energy directly by water, or indirectly through chromophores of biofabrics. Laser radiation of near-infrared spectrum (0.9 - 2.1 µm) is poorly absorbed by water and fabric chromophores, as a result is the deep thermal damage to biofabric. CO2 laser radiation mid-IR spectrum (10.6 µm) is absorbed by water well but the laser cannot operate in a pulsed mode, which does not allow realizing high peak power per pulse, so necessary for the surgery.
Small Russian innovative company is developing the next generation of surgical instrument. It is two-wave laser system, which technical parameters make possible to perform bloodless surgical operations on soft, bone and cartilage without signs of their thermal damage. The developed laser system consists of two lasers: 1) diode-pumped Er: YAG laser provides pulse duration of 1 ms and a peak power up to 50 kW, the wavelength of 2940 nm has a maximum in the absorption spectrum of water, the incision or removal of tissue is based on the physical effect of the cold thermal ablation without damaging it. 2) Laser diode module of 405 ± 10 nm provides a pulse duration of 100 ns and a peak power up to 20 kW, the wavelength range of 405 ± 10 nm in the absorption spectrum of water is in the "spectral window" selectively and intensively as possible is absorbed by oxyhemoglobin, affecting the blood vessels prevents bleeding (selective photothermolysis).
The main purpose of the laser system is rendering of high-tech medical care: high-precision surgical operations on the brain, heart, parenchymatous organs (including transplantation), as well as bone and cartilage.
Company is looking for the industrial manufacturing enterprises producing equipment for high-tech medicine interested in technical cooperation and strategic partnership.
Advantages and Innovations:
Innovative aspect consists in simultaneous impact of radiation energy of two lasers on biofabrics. This allows getting efficient bloodless incision or evaporation of pathological tissue without thermal damage.
Advantages:
- High level of surgical safety;
- Incision of soft, bone and cartilage tissue up to 5 microns;
- Radiation energy does not cause thermal damage to tissue;
- Bleeding is completely absent during the operation;
- No risk of HIV infection, hepatitis and other diseases;
- Operating time shortens in half;
- Postoperative period is without complications and pain;
- Rehabilitation period is reduced three times;
- There is no scar tissue on the incision;
- Low cost for this class of laser system.
