TOMSK, Nov 21 – RIA Tomsk. Radiophysics of Tomsk State University (TSU) created a working model of an ultrasonic surgical instrument for tissue adhesion and were approved by the industrial partner; prototype is planned to be created by 2020, after which the first domestic device will arrive in the markets of Russia, the press service of the university reported on Wednesday.
Earlier it was reported that TSU scientists are planning to develop ultrasonic signal control algorithms for surgical instruments, with the help of which, in particular, it is possible to “glue” the vessels faster and safer, to remove blood clots and eye cataracts. Such devices are currently manufactured only abroad, but they consume too much energy and overheat in the hands of the surgeon.
"A working model of an ultrasonic surgical instrument for coagulation (adhesions) of tissues was developed by radiophysics of TSU. The industrial partner of the project JSC "NIKOR SPA" approved the model. The next step will be the creation of a prototype, which will be ready by 2020 and launched on the market of Russia and neighboring countries", – is said in the statement.
According to the press service, the surgical instrument for tissue adhesion is created on the basis of an ultrasonic wave guide - an artificial guide channel with sound reflecting walls in which the wave propagates. The resonance of its oscillations is calculated in such a way that the connections experience a minimum load, do not overheat, and the instrument itself can work longer.
It is added that during operation of the waveguide, the amplitude of oscillations increases, thanks to what the tool can affect materials and cause different effects. The device, in addition to medical, there are options for technological application – mixing of various substances, for example, oils with water, cutting of rubber and welding of plastics.With reference to the project manager, the professor of TSU Dmitry Sukhanov, it is noted that, at present, radiophysics are practicing on a model different modes of operation, checking numerical models and conducting experiments. Work on creation of a prototype of an ultrasonic surgical instrument is on schedule. The international presentation of the project will take place in November 2018.
