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.

[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.

[Reinforcement of the operating elements of medical instruments].

Reinforcement processes were analysed to assess the possibility of their use for the medical apparatus production. It was shown that one of the ways to make medical instruments more durable is the reinforcement of their operating surfaces with wear-proof, corrosion-resistant and hard materials by means of soldering, sputtering and fuse on.

[Study and calculation of friction losses in microturbines and burs for dentistry].

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.

[Study and design of microturbines for medical practice].

The methodology of designing performance for medical microturbines is described. The method has been verified when designing the net moment and power of a turbine tip HTC-300-02 and a micromotor MMp-20. The comparison of theoretical and experimental data has shown the discordance to be less than 5%.

[Characteristics of microturbines for dentistry].

In order to design high efficient pneumatic actuators for stomatology the experimental studies of microturbines operating in air turbine handpieces have been performed. Specially developed experimental set and torque meter-tachometer have been used for the purpose. As a result, the main parameters of commonly known stomatologic pneumatic instruments are specified, and the ways of their modifications are determined as well.
