Description

Multi-variable focal extracorporeal shock wave therapy

The present invention relates to an extracorporeal shock wave therapy device.

In general, a shock wave creates a waveform with a strong pressure for a very short time in various ways, and uses this to stimulate the damaged tissue to induce a therapeutic effect.

In addition, a shock wave is defined as a pressure wave generated by the high-speed oscillation phenomenon of an explosive electric spark that causes a strong pressure change in an elastic material such as gas, liquid or solid. It is a sound wave with strong mechanical force and pressure. and ultrasound are clearly distinguished.

In addition, the shock wave is transmitted at the speed of the ultrasonic wave and has a characteristic of retaining strong energy continuously during the transmission process.

Extracorporeal Shock Wave Therapy (ESWT) is largely divided into focus type and radial type depending on the principle of occurrence.

The centralized type collects shock waves at one point through a dust collecting plate, and the radial type generates shock waves by compressing air using a pendulum, etc., also called a pneumatic type. In the concentrated type, a strong shock wave can be generated because the shock wave is collected and stimulated at one point.

The concentrated type may be classified into an electrohydraulic type, an electromagnetic type, and a piezoelectric type according to a method of generating a shock wave. Among them, the electromagnetic method is the most stable and can generate a constant shock wave, so it is widely used in research and is known to have good clinical effects.

The electro-hydraulic type is a method in which the wave generated by generating an electric spark is reflected from the dust collecting plate and collected at one point. Electromagnetic treatment is a method of treatment by collecting shock waves generated by a magnetic field at one point. And, the piezoelectric type is a method of collecting shock waves generated from a small-sized electric element at one point and treating it.

In particular, the piezoelectric shock wave therapy device, which is a piezoelectric type among concentrated types, stimulates the body part by using the secondary piezoelectric effect (reverse piezoelectric effect) of the piezoelectric effect element to stimulate the body part, thereby reducing the pain occurring in the body part. It is a medical device that can relieve chronic pain in the musculoskeletal system while stimulating the patient's own self-healing.

In the conventional concentrated method, since the focal length is fixed for each device, it is inconvenient to adjust the thickness of the pad according to the depth of the lesion.
