[Evaluation of the healing of skin wounds inflicted by steel scalpels with various degrees of sharpness].
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.

[Outlook for growth in the manufacture of instruments used in oral medicine].
Introduction of newer dental instruments is foreseen owing to the perfection of manufacturing methods, equipment and rigging.
[Lubricant-free piston compressors for mechanized medical instruments].
Piston compressor without lubrication with air blow to packing rings by plunger, disposed in subpiston space, is recommended as the basic scheme of construction of a power supply unit for medical pneumatic tooling. The construction reduces a leak of the compressive medium, increasing the efficiency of a compressor and seal reliability.
[Principles of constructing miniature rotation-plate pneumatic motors].
Tiny rotation-plate pneumomotors be made with a rotor lengthened to 3-5 diametres of a rotor with simultaneous gaz supply through 2-3 channels. It is recommended to use the kinetic energy of air current and a piston system of pneumomotor start.
[Pneumatic motors and nozzles used in traumatology and surgery].
New original constructions of pneumatic motors and nozzles (with guaranteed start up of a pneumomotor with a nozzle) are described. They ensure non-traumatic treatment of osseous tissues and exclude the breakage of a cutting instrument in work.
[Basic principles of the design of motion converters in instruments for the mechanized treatment of bone tissues].
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.
