FIELD: medical equipment. ^ SUBSTANCE: the apparatus has a controlled power source and an inductor enveloping the working cavity. The inductor consists of a magnetic circuit made of rings wound of ships of electrical-sheet steel, and a winding. The winding is laid along the magnetic circuit. Holes are made in the magnetic circuit rings in radial directions, studs are fastened in the holes with the aid of nuts through insulating bushes. The studs are fastened in the framework for changing the clearance between the magnetic circuit rings and the framework. In thickness the rings represent a core of sheet steel, they are tightened by nuts in the points of passage of the studs. The longitudinal components of the framework are made of several sections interconnected by insulating inserts. ^ EFFECT: simplified construction, enhanced adaptability to manufacture, reduced loss of power and reduced noise at operation of the apparatus. ^ 3 dwg |
