Description

(54) DEVICE FOR IMPACT ON REPARATIVE BONE TISSUE REGENERATION

The generators of 7 square pulses and through it to the input of the synchronizer 1. In addition, the outputs of all generators 2,4,5 and 7 through the adder 8 are connected to the output stage 9.

The device works as follows.

After connecting the device, the synchronizer starts working, while there is no signal at the output for a certain time, and after the time has elapsed, the synchronizer generates a short pulse that starts the generator of 2 sinusoidal oscillations. The damped sinusoidal signal from the generator 2 is fed through the adder 8 to the output stage 9 of the device. As soon as the signal amplitude reaches a level close to O, the discriminator 3 amplitude starts the generator 4 of a rectangular pulse, which sequentially generates one positive and one negative pulse (these signals also go through the second input of the adder 8 to the output stage 9). At the end of the negative half-wave, a generator of 5 sinusoidal oscillations is started, and the signal from which is postponed through the third input of the adder 8 to the output stage 9 is damped. 1 d; one positive and one negative impulse, which are received for whose chg.-: -; /; 1 and input of the sender 8.
