[Optimization of methods and improvement of technical means in combination with the nonspecific reparative regeneration stimulator ximedone in dermatoplasty surgery]. / Optimizatsiia metodov i sovershenstvovanie tekhnicheskikh sredstv v sochetanii s nespetsificheskim stimuliatorom reparativnoi regeneratsii ksimedon v kozhno-plasticheskoi khirurgii.

Treatment of extensive tissue defects should be complex, whose basis is an early free skin plastic repair with obligatory addition of agents that enhance the reparative capacities of tissues. For this, the authors propose a number of original appliances (forceps, variants of dermoperforators, bandage, etc.) and drugs, such as ximedon (tablets, 5-10% aqueous solution, lanolin-vaseline-based ointment, talc-based powder), whose clinical trials in 300 patients have shown their high therapeutical effect. The time of preparation of the wound surface for dermatoplastic interventions became shorter and the frequency of poor outcomes of operations reduced.

[Evaluation of the healing of skin wounds inflicted by steel scalpels with various degrees of sharpness]. / Otsenka zazhivleniia kozhnykh ran, nanesennykh sta'lnymi ska'lpeliami s razlichnoi zatochkoi.

Experiments on 200 animals and clinical use of 300 scalpels differing in the width of the cutting edge showed that operative lineal skin incisions made with a sharp instrument (a ruby knife, razor, scalpel with a 0.8 microns cutting edge) heal better and quicker than those inflicted with a blunt scalpel of serial production with a cutting edge 12.5 microns wide. Such blunting of scapels occurs after two operations and traditional methods of sterilization of the instruments. Mechanical damage of the instruments during cleansing and washing is most important in the clinic.

[Basic principles of the design of motion converters in instruments for the mechanized treatment of bone tissues]. / Osnovnye printsipy konstruirovaniia preobrazovatelei dvizheniia v instrumentakh dlia mekhanizirovannoi obrabotki kostnykh tkanei.

The main tendency in designing mechanized medical instruments is developing systems with automatic fine adjustment and self-regulation. The automated gear adjustment, self-regulating mouthpieces and cutting tools create a flexible automated system with optimal cutting regime. The instruments do not overheat bone tissues which helps to avoid unnecessary traumatization.

The method to compute friction loss in medical microturbines and tips at the stage of their development is proposed. It is verified when designing friction loss of the following devices: a turbine tip HTC-300-02, a pneumatic micromotor MMP-20, and micromotor tips (NVP-30M) and (NP-30M). The method may be useful in estimated designs of friction loss.
