Description

Electromagnetic Extracorporeal Shock Wave Therapy Using Disc-Type Coils

The present invention relates to an electromagnetic type extracorporeal shock wave therapy device using a disk-type coil, and more particularly, by applying an impulse current to the disk-type coil to form an instantaneous magnetic field and to generate a shock wave from the disk by the magnetic field, It relates to an electromagnetic-type extracorporeal shock wave therapy device using a disk-type coil that performs lithotripsy.

The shock wave generator may be largely divided into a piezoelectric type, an electrohydraulic type, and an electromagnetic type.

In this case, the electromagnetic shock wave generator is a device that generates a shock wave by using an electromagnetic effect. By forming a magnetic field in a coil and inducing the metal plate, the vibration of the metal plate forms a shock wave.

Since the conventional electromagnetic shock wave generator has a low energy concentration because the shock wave is basically dispersed in forming a shock wave, a technical solution for efficiently concentrating the shock wave is required.

In addition, in the conventional electromagnetic shock wave generating device, the shock wave generating unit is used in a state spaced apart from the patient's skin in delivering the shock wave to the patient, which causes a problem in which energy is reduced, so that the shock wave is in direct contact with the patient. There is a need for a technical solution that can transmit shock waves with high energy density.

In addition, since the conventional electromagnetic shock wave generating apparatus heats the coil when the shock wave is formed, a technical solution is needed to efficiently cool the coil and efficiently transmit the shock wave.

Here, both ends of the magnetic coil 1 are electrically connected to the connection terminal 1a in a state in which a copper wire is wound in a coil shape of a coil circular plate. Here, the current applied to the magnetic coil 1 is an impulse current, which instantaneously forms a magnetic field.

The insulating coupling part 2 is coupled to the magnetic coil 1 in the form of a circular plate coil to insulate the magnetic coil 1 and fix the magnetic coil 1 in the form of a plate. In this case, the insulating coupling part 2 may be formed of an insulating material such as epoxy or glass. Here, in the case where the magnetic coil 1 is not insulated by the insulating coupling part 2, a short-circuit by the contact of the disk pad part 3 or the contact of the liquid medium 5 causes the coil to melt instantaneously. will occur

In this case, the acoustic lens unit 6 may be formed to include a convex lens unit 6a and an outer cover 6b.

The convex lens part 6a is formed in a convex lens shape and is arranged so that the focal axis of the convex lens coincides with the origin of the disk pad part 3 . In this case, the convex lens unit 6a serves to integrate the shock wave. In addition, the convex lens unit 6a is operated with the external surface in contact with the patient's skin S1, and the integrated shock wave is output by penetrating the patient's skin S1 in a state where energy is concentrated, thereby performing a lithotripsy function. will do Since the convex lens unit 6a is operated in a state in contact with the patient's skin while accumulating the shock wave, it is possible to transmit the shock wave to the patient with high energy density.

The outer cover 6b is integrally formed with the convex lens unit 6a, and extends outside the convex lens unit 6a to surround the liquid medium unit 5 and the disk pad unit 3 . Here, the outer cover (6b) is formed integrally with the convex lens part (6a), so that the liquid medium part (5) is accommodated so as not to leak to the outside.

The coupling ring 7 is formed in a ring shape and is coupled to the outer surface of the outer cover 6b of the acoustic lens unit 6 . The coupling ring 7 may be fitted with the outer cover 6b by pressing or pressing in order to be strongly coupled to the outer surface of the outer cover 6b of the acoustic lens unit 6 .

When explaining the operation of the electromagnetic extracorporeal shock wave therapy device using the disk-type coil as described above, first, when an impulse current is instantaneously passed through the magnetic coil 1, the magnetic coil 1 generates an impulse magnetic field. , an eddy current is generated on the surface of the disk pad part 3 by the impulse magnetic field to generate a Lorentz force, and the disk pad part 3 where the Lorentz force is generated is momentarily strongly vibrated.

At this time, the temporarily vibrated disk pad unit 3 forms a shock wave in both directions, and then the liquid medium unit 5 transmits the shock wave generated from the disk pad unit 3 to the convex lens unit 6a. Next, as shown in FIG. 8, the convex lens unit 6a diffracts the plane wave type shock wave generated from the disk pad unit 3 so that the shock wave based on the focus of the convex lens unit 6a is integrated. Then, the shock wave focused on the convex lens unit 6a is converted into a rectangular shock wave S2 toward the skin S1 and penetrates, and the rectangular shock wave S2 is a shock wave of higher energy density than the conventional electromagnetic shock wave. It performs the crushing function.

In particular, in the electromagnetic type extracorporeal shock wave therapy device using the disk-type coil of the present invention, when the disk pad portion 3 generates a shock wave by the magnetic coil 1, the disk pad portion 3 by the shock wave reflector 4 It is possible to efficiently concentrate the energy of the shock wave because it reflects the shock wave in one direction among the shock waves generated on both sides of the

In addition, the electromagnetic extracorporeal shock wave therapy device using the disk-shaped coil of the present invention integrates the shock wave transmitted through the liquid medium part 5 in the convex lens part 6a of the acoustic lens part 6, while the acoustic lens part 6 ) of the convex lens unit 6a concentrates the energy in a state in which it is in integrated contact with the patient's skin, so that the energy of the shock wave can be more efficiently integrated.
