ONKOCET Ltd. has exhibited the devices from its portfolio on the MEDTEC UK exhibition in Birmingham, April 2011 through our partner Medical & Partners.
For achievement the effect of partial drying and formulated above tasks there is no need for using entire temperature potential of air-plasma flow (HPF). Sufficient to ensure in the place of the contact of plasma jet with the cloth temperature in the range from 1000°C to 2000°C. The flow charts of the sparing coagulation are shown in the figure.
The sparing coagulation can be carried out as by coagulator (Fig. a), so by stimulator-coagulator (Fig. b). With the use of a coagulator the distance from the outlet to the region of coagulation must be not less than 25 mm. Visually this approximately corresponds to the end of the luminous part of the plasma torch of coagulator. The decrease of distance from the outlet to the region of coagulation will lead to the excess of the temperature limit into 2000°C.
The thermo-physical processes, proceeding during the sparing coagulation, are in many respects similar to the processes, proceeding during the traditional coagulation, but in this case low temperature potential flow does not make possible to be formed for the complete region of thermal changes. Process is limited to the formation of the small zone of spongy necrosis (SLN), zone of compact necrosis (CLN) and zone of paranecrosis. As a result this action the elastic film of lusterless nuance with a thickness not of more than 200 mkm is formed on the surface of cloth, which also is the purpose of the sparing coagulation.
With conducting of the sparing coagulation by stimulator-coagulator the distance from the outlet of manipulator to the cloth is minimal (Fig. b), since the temperature of the escaping flow does not exceed 1000°C.
This way, if it is necessary to realize the sparing coagulations on large surface it is possible to use a coagulator, and if it is necessary to coagulate the bounded spaces - stimulator-coagulator.
