Description

In vitro therapy

The present invention relates to an extracorporeal therapeutic apparatus, and more particularly to an apparatus for extracorporeal shock wave therapy (ESWT).

Shockwaves can be created in a very short time by a variety of methods, creating strong pressure waves that can be used to stimulate damaged tissues to produce therapeutic effects.

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

The concentrated type collects the shock wave at a spot through the dust collecting plate, and the radial type is a pneumatic type in which shock waves are generated by compressing the air using a pendulum or the like. The concentrated type generates a strong shock wave by collecting a shock wave to a point and applies a stimulus, and the radial type spreads radially from the shock wave generation site. Therefore, the strength of the shock wave gradually decreases as the distance increases.

The concentrated type can be divided into electrohydraulic, electromagnetic, and piezoelectric according to the method of generating the shock wave. Among them, the electro magnetic type is most stable and can produce a constant shock wave, so it is widely used in researches and has a good clinical effect.

The electric hydraulic method is a method of collecting the wave generated by the electric spark from the dust collecting plate and collecting it at one point. Electromagnetism is a method of collecting shock waves generated by a magnetic field and collecting them at one point. The piezoelectric equation is a method of collecting shock waves generated from a small-sized input device and collecting them at a single point.

Since the focal length is fixed for each device in the concentrated type, it is inconvenient to adjust the thickness of the pad according to the depth of the lesion. In addition, due to the nature of the shock wave, the patient may feel pain and discomfort due to sharp and strong stimulation.

Since the radial type compresses air by pendulum to make shock waves, the strength of the shock wave is lower than that of the concentrated type, so the shock wave can not be transmitted to the deep lesion. The intensive therapeutic effect appears mainly at the cellular level and the radial type at the tissue level.

The present disclosure intends to provide a technical feature relating to an apparatus for treating and treating an affected part of a patient by irradiating a shock wave using an extracorporeal treatment device.

According to an exemplary embodiment of the present disclosure, a diaphragm of a concave shape for generating a shock wave by a vibration caused by an electromagnetic field and irradiating the shock wave to a focus region; A concave shaped electromagnetic field generating unit disposed adjacent to a rear surface of the diaphragm to generate an electromagnetic field to vibrate the diaphragm; And a housing for fixing the diaphragm and the electromagnetic field generating unit. An extracorporeal therapeutic device can be provided.

More particularly, the present invention relates to an extracorporeal shock wave therapy (ESWT) system capable of generating stable shock wave energy having a constant wavelength, and more particularly, to an extracorporeal therapeutic apparatus capable of effectively delivering shock wave energy to a affected area, ). &Lt; / RTI >

At first, the shock wave treatment method was used for lithotripsy because the effect of shock wave was considered to be caused by simple mechanical stimulation. Over time, however, several studies have reported increased expression of cytokines at the cellular level, stem cell infusion, and antibacterial effects, and their use is expanding in various areas.

Generally, the extracorporeal shock wave treatment method repeatedly transmits the shock wave to the body by contacting the extracorporeal treatment unit to the treatment area where the pain is felt such as degenerative lesion of the musculoskeletal system, rupture of the ligament, and lime formation around the joint, It is a therapy that promotes the healing of lesion tissue by inducing damage and inducing the generation of new blood vessels and increasing blood flow supply.

Currently, extracorporeal shock wave therapy devices used worldwide are divided into electro hydraulic, electromagnetic, and piezoelectric according to the energy output method.

Electrohydraulic is classified as a high-energy type, in which energy is obtained by discharging an electrode in a water-filled container. An electromagnetic type is a method of obtaining energy through a coil like an audio speaker. The piezoelectric element type is a method of obtaining energy by vibrating the piezoelectric element by electrically stimulating the piezoelectric elements. Piezoelectric and electromagnetics are known to have relatively low pain experienced by the patient during low energy procedures.

Electrohydraulic shock absorbers generally have a hemispherical reflector, and the reflector is provided with an electrode for actually generating a wavelength. A power supply for supplying electricity is connected to the electrode. According to this configuration, both ends of the electrode disposed in the water cause a spark discharge when a voltage is applied. When a spark discharge occurs, a pressure wave is generated in the water and a spherical wave source is formed. Such a power source spreads in a spherical shape, and a part thereof is reflected on a reflector or concentrated in a direct focus region to generate a shock wave. The generated shock wave can be used for treatment or surgery by irradiating the focus area with the treatment device directed to the affected part desired by the patient.

Another type of electromagnetic wave extracorporeal shock wave therapy device is generally formed of a circular strong ceramic and consists of a circular support having an electric coil, an insulating foil, a metal membrane, a focusing lens, and the like. The electric coil is connected to the power supplying device. According to such a configuration, when a current of about 10 to 20 kA is applied by a power supply device, an electromagnetic force, that is, a repulsive force, is generated between the electric coil and the metal membrane by Lenz's law, causing the metal membrane to vibrate. The vibration of the metal membrane generates shock waves according to the shape of the metal membrane in the surrounding fluid. The generated shock wave can be focused on the focus area by the focusing lens and used for treatment and treatment.

In another way, the piezoelectric sub-shock wave therapy device generally consists of a spherical focusing plate and a pulsed power supply. A large number of piezoelectric elements are attached to the curved surface of the focusing plate. When a momentary power is supplied to a plurality of piezoelectric elements through a pulse power supply, a short pulse pressure wave is generated in each piezoelectric element. have.

However, the conventional extracorporeal shock wave therapy apparatus has the following problems. First, in the case of electrohydraulic type, the generation of sparks used as the shock wave source in the extracorporeal shock wave therapy apparatus is inherently unstable, and the characteristics of the shock wave are changed by 50% or more even in the same setting range. Even in the case of the electromagnetic external shock wave therapy device and the piezoelectric shock external wave shock wave treatment device, stability and reliability may be a problem in that shock waves generated are varied in the range of about 5%, and uniform shock waves can not be provided.

In addition, the use of the electrohydraulic external shock wave therapy device is limited due to a spark that can be used as an impact source in a very narrow pulse power energy range. Electromagnetic wave extracorporeal shock wave therapy equipment can be greatly changed according to the characteristics and fixing method of the metal membrane. In the piezoelectric shock wave wave therapy device, pulse power source energy varies greatly, but there is a problem that saturation phenomenon and piezoelectric element are damaged at high output.

In addition, the electrohydraulic external shock wave therapy device has a disadvantage of requiring additional equipment such as an ear plug at the time of the operation because it generates noise of about 100 decibels or more. In the piezoelectric shock wave external shock wave therapy device, There is a problem that the output of the shock wave generation is low and must be made large.

Furthermore, when an electric hydrostatic shock wave generator generates about 2,000 shock waves, the electrode is worn and must be replaced. Electromagnetic exter- nal shock wave therapy devices can damage or rupture the metal membrane when shock waves are generated tens of thousands of times. The piezoelectric shock absorber has a problem that the piezoelectric element is damaged or ruptured due to high energy pulse power.

A conventional electromagnetic extracorporeal shock wave therapy device has a structure in which a cylindrical membrane for generating an electromagnetic field is formed at an inner central portion and is oscillated by an electromagnetic field generated by pulse power to generate a shock wave. The generated shock wave is reflected on a parabolic reflector surrounding the cylindrical membrane and focused on the focus area or is converged while passing through the focus lens, so that the affected part is used for treatment or surgery. According to the conventional method, there is a problem that the shock wave is reflected or attenuated gradually as it passes through various media, resulting in a decrease in efficiency. Therefore, the conventional electromagnetic shock wave therapy apparatus is an extremely low efficiency system, and the energy to be converted into the shock wave is extremely low as compared with the energy supplied. Also, it was less reliable because the focus area was not correct due to multiple refractions. Recently, a cylindrical shock wave therapy apparatus having a taper shape has been studied, but it has not been largely deviated from the conventional method.

The present invention is an extracorporeal device 2000 for providing an effective shock wave treatment method while solving the problems of the conventional ESWT. The extracorporeal treatment apparatus 2000 of the present invention may include a connecting portion 1100 for supplying signals, power, refrigerant, etc. between the impactor 1000 and the external machine 1200, and between the impactor 1000 and the external machine 1200 have. Specifically, the external shock absorber 1000 may include a vibration plate 210 and an electromagnetic field generating unit 220. The diaphragm 210 and the electromagnetic field generating part 220 may be formed in a concave shape similar to each other or may be arranged to be superposed. Such a technical feature can simplify the structure of the extracorporeal treatment device 2000, thereby facilitating the manufacture and improving the energy efficiency.

However, this configuration may be partially changed depending on the method of use and manufacturing method, and some components may be replaced or omitted with other components. For example, the external machine 1200 may be included in the impactor 1000, in which case the connector 1100 may be omitted.

The extracorporeal treatment apparatus 2000 includes a vibrating plate 210, an electromagnetic field generating unit 220, a housing 230, a cooling unit 240, a gel pad 250, a power source unit 310, (320) and a control unit (330). However, the present invention is not limited thereto.

In an embodiment of the present invention, the extracorporeal treatment apparatus 2000 may include a diaphragm 210 having a concave shape for generating a shock wave by the vibration caused by the electromagnetic field and irradiating the shock wave to the focus region. The extracorporeal treatment device 2000 may include an electromagnetic field generating unit 220 disposed adjacent to the rear surface of the diaphragm 210 to generate an electromagnetic field to vibrate the diaphragm.

In one embodiment of the present invention, diaphragm 210 may be a thin concave plate. The diaphragm 210 may be made of an elastic material such as resin, paper, metal, or the like. The diaphragm 210 may be made of a metal that is resistant to heat and can sustain an impact applied continuously. The diaphragm 210 may be formed in a hemispherical shape so that the rim of the diaphragm may be fixed so as to be held in contact with the housing 230. Although not shown, in order to prevent the vibration of the diaphragm 210 from being transmitted to the housing 230 when the diaphragm 210 is supported by the housing 230, A member can be used for fixing. In another embodiment of the present invention, the diaphragm 210 may include a hole in its inner central portion, and any support (e.g., post) may pass through the hole to secure the diaphragm to the housing 230 Lt; / RTI >

The concave shape of the diaphragm 210 may be in the form of a parabola, such as an antenna. Unlike the conventional electro-magnetic external shock wave therapy device that uses a reflection plate or a lens to focus a shock wave generated in a diaphragm, the diaphragm of the present invention is capable of focusing a shock wave directly generated at a geometrically fixed point have. Therefore, the shock wave can be reduced or deformed by being passed through various media.

In one embodiment of the present invention, the electromagnetic field generating portion 220 may be disposed adjacent to the rear surface of the diaphragm 210. Also, the electromagnetic field generating unit 220 may be formed in a concave shape similar to the diaphragm 210. The concave shape of the electromagnetic field generating portion 22 may be specifically a parabolic shape such as an antenna. The electromagnetic field generating unit 220 may be disposed in a state of wrapping around the diaphragm 210. The arrangement in which the electromagnetic field generating unit 220 and the diaphragm are disposed adjacent to each other in a similar manner may convert electric energy into kinetic energy It is possible to reduce the energy damping in the process. In addition, since the diaphragm 210 and the electromagnetic field generating unit 220 are similar in shape, energy to be scattered or refracted can be reduced as much as possible to enhance energy efficiency.

In one embodiment of the present invention, the electromagnetic field generator 220 may include at least one electromagnet. The electromagnet may specifically include an electric coil, an insulator, and electrodes capable of being supplied with electric power from the power source unit 310. Also, the electromagnet may be waterproofed to prevent a failure due to the refrigerant flowing into the electromagnetic field generator 220.

In an embodiment of the present invention, the electromagnetic field generating unit 220 may be supplied with power from the power source unit 310 to allow an impulse current to flow through the electric coil. The electromagnetic field generated by the electric coil can vibrate the diaphragm 210 adjacent to the electromagnetic field generating portion 220 finely. This vibration becomes a shock wave source that emits in accordance with the concave shape of the diaphragm 210, so that the generated shock wave is concentrated in a geometrically constant area (i.e., a focus area) by the concave shape of the diaphragm. The shock waves thus focused can be irradiated to the affected part of the patient and used for treatment or treatment.

In one embodiment of the present invention, the diaphragm 210 is manufactured in a concave shape to simultaneously serve as a lens and a diaphragm. This configuration can have the effect of preventing energy from attenuating as it passes through various media. Also, the diaphragm 210 having a concave shape is easy to manufacture, and the unit cost can be reduced, which is economically advantageous. Also, according to the embodiment of the present invention, the extracorporeal treatment device 2000 of the present invention has an advantage of being able to generate shock waves using a relatively low voltage because of high energy efficiency, and thus, there is no consumable item and can always be reused.

In one embodiment of the present invention, the electromagnetic field generating portion 220 may include one electromagnet of a concave shape adjacent to the back surface of the diaphragm. In another embodiment of the present invention, the electromagnetic field generating portion 220 may include a plurality of electromagnets disposed in a predetermined pattern adjacent to the back surface of the diaphragm. Where the predetermined pattern may be radial. However, the present invention is not limited thereto.

In detail, the electromagnetic field generating part 220 may include one electromagnet of a concave shape, and one electromagnet may be formed in a concave shape similar to a diaphragm. When the in vitro treatment device 2000 employs the electromagnetic field generating part 220 including one electromagnet, the structure of the extracorporeal treatment device may be simplified, which may be advantageous in disposing the electric wires and fixing the electromagnetic field generating part 220. In another embodiment, the electromagnetic field generating portion 220 may include a plurality of electromagnets arranged in a predetermined pattern. When the extracorporeal therapeutic apparatus 2000 employs the electromagnetic field generating unit 220 including a plurality of electromagnets, the intensity of the shock wave can be increased or the focus area can be finely set by using several electromagnets. Even when a plurality of electromagnets are used, the predetermined pattern may be radial so that the diaphragm, which is a technical feature of the present invention, can simultaneously perform the roles of the lens and the diaphragm.

In an embodiment of the present invention, the extracorporeal treatment apparatus 2000 may include a diaphragm 210 and a housing 230 for fixing the electromagnetic field generating unit 220.

The pole portion 232 has a bolt shape and penetrates the center of the electromagnetic field generating portion 220 and the cooling portion 240 to fix the electromagnetic field generating portion 220 and the cooling portion 240 inside the housing 230 . In addition, the column portion 232 can be provided with a passageway through which the refrigerant, electric power, electric signals, and the like are transmitted. However, the shape of the housing 230 can be modified to any extent according to various embodiments.

The housing 110 may be formed with a predetermined accommodation space for accommodating components constituting the impactor 1000. In addition, the accommodation space may also include a movement space that enables the operation of the components. For example, the pillars 232 may form a space therein to allow refrigerant or a power supply line to pass therethrough. The column portion 232 may provide a space through which the injection portion 243 and the discharge portion 242 for circulating the refrigerant can be connected to the refrigerant supply pipe and the refrigerant recovery pipe, respectively.

An elastic member may be attached to one side of the housing 230. Such elastic members may include, but are not limited to, polyvinyl acetate, polyurethane, rubber and / or silicone. For example, the grip portion included in the body portion 233 of the housing 230 may further include a silicon member or the like. In this way, the extracorporeal device 2000 can improve the grip feeling during use and prevent slippage in the user's hand.

According to a further embodiment of the present invention, the outer surface of the housing 230 may be made of the same material as the inner surface of the housing 230. Or the outer surface of the housing 230 may be made of a member different from the inner surface of the housing 230. For example, the material constituting the inner surface of the housing 230 is an elastic member, and a resilient synthetic resin such as polyvinyl acetate, polyurethane, rubber, or silicone may be selected. Further, the material constituting the outer surface of the housing 230 may be made of a hardenable member such as a plastic material or a plastic member.

Accordingly, a power supply line for supplying power to the electromagnetic field generating unit from the power supply unit 310 and a refrigerant supply pipe may be wired together inside the housing 230.

The electromagnetic field generator 220 and the diaphragm 230 located on the front surface of the body part 233 need not be cooled without cooling the entire housing 230 including the body part when the refrigerant surrounds the electromagnetic field generating part 220.
