Prevalence of gunshot wounds in modern world is associated with criminalization of society, terrorist threats, increase of a number of local military conflicts and civil unrest. Search and devel-opment of methods for reducing blood loss, accelerating the healing of postoperative wounds and scars resorption is an important goal of modern surgery, the solution of which is facilitated by the use of ultrasound. The use of ultrasonic surgery in military medicine and the use of piezoelectric elements as the source of ultrasound are perspective.
Primary surgical treatment of wounds is the main method of preventing the development of se-vere infectious complications of gunshot wounds. When using an ultrasonic surgical instrument, an urgent task is to disinfect it before and after the operation. The purpose of this work consists in the development of disinfection method for destruction of pathogen of infection on the cutting part of ultrasonic surgical instrument. In the paper a diagram is worked out and the design of tension transformer is conducted for ultraviolet emitters, the dock-station is constructed for a mobile ultrasonic surgical instrument for its loading and the process of desinfection. The model of ultrasonic surgical instrument and disinfection method for destruction of pathogen of infection on the cutting part of ultrasonic surgical instruments are developed. The worked out surgical instrument is mobile and autonomous, that is provided by the use of Li-ion accumulators, reliable and has considerable tenure of employment of active elements from piezoceramics, comfortable in exploitation and simple in a management due to the use of ergonomic handle.
