Description
Technical Field
The present invention relates to a shock wave therapeutic apparatus, which is an extracorporeal shock wave therapeutic apparatus in which a shock bullet moving in a cylinder generates strong shock waves by adding compressed air to an initial portion, and an air storage device is provided outside the cylinder to maintain a certain pressure to generate stable shock waves.
Background
In general, in vitro shock wave therapy is a therapy for treating an affected part, which is affected by pain such as degenerative diseases of musculoskeletal system, torn ligaments, and grey matter formed around joints, by repeatedly transmitting shock waves to the body to cause temporary fine lesions at the affected part, thereby inducing neovascularization, increasing blood supply, and promoting the healing of affected tissues.
The above-mentioned conventional shock wave treatment apparatuses can be roughly classified into two types, one is a shock wave generated by applying an increased voltage, and the other is a shock wave generated by compressing air.
However, the first method has a disadvantage that the voltage used is 25000V and the parts used in the circuit are expensive parts imported, and therefore, the manufacturing cost is high.
However, the apparatus using the compressed air method is heavy and bulky, and the compressor is very noisy in operation in order to generate the compressed air, and an air pressure adjusting device and a switch are required in order to adjust the impact energy, which increases the manufacturing cost.
A shock wave generator that uniformly distributes a range of action in an easier and more economical manner than the above-described method has been registered in korean laid-open license No. 2010-0005766.
The prior art documents have a merit that a shock wave generated by the impact with the transmission part is transmitted to the affected part through the shock wave discharge surface after the impact part makes a linear motion, thereby simply treating soft tissue or hard tissue. However, when the hitting portion is driven in the cylinder, a part of energy loss occurs due to friction. Thus, the shock wave energy is reduced, and there is no auxiliary method for adjusting the pressure when the striking part flows in the cylinder, so that there is a disadvantage that it is difficult to generate stable shock waves.

Detailed Description
The following is a detailed description with reference to the drawings with reasonable examples of implementation added. Corresponding reference numerals are attached to the constituent elements of the drawings, and the same elements are denoted by the same reference numerals as much as possible. The construction and operation of the article of manufacture as illustrated in the figures or described in connection with the article of manufacture will be more fully described in the examples. The technical idea of the present invention and the core constitution and action thereof are not limited to the above.
FIG. 1 is an exploded perspective view of an extracorporeal shock wave treatment apparatus. FIG. 2 is a cross-sectional view of an extracorporeal shock wave treatment apparatus.
The extracorporeal shock wave treatment apparatus uses the shock energy generated when compressed air collides, and has a pistol shape (not shown).
The inner part of the shell is provided with the components of the shock wave therapeutic apparatus. As shown in fig. 1 and 2, the pneumatic impact hammer is composed of a solenoid valve 10 for controlling the ejection of compressed air, an actuator 20 having an air nozzle 22 communicating with the solenoid valve 10, an air pipe 70 having a cylinder 30 for moving the compressed air ejected from the solenoid valve 10, an impact bullet 40 linearly moving in the cylinder 30, a muffler 50 on the outer surface of the cylinder 30, and an impact transmitter 60 for transmitting an impact wave generated by a direct impact force generated when the impact bullet 40 linearly moves.
The front end of the air pipe (70) is provided with a shell (80) for fixing the impact transmitter (60). The housing (80) is screwed down in the form of a screw, and the sleeve can be manually released.
A plurality of coils are wound ON the solenoid valve (10), and the opening and closing of the solenoid valve (10) are controlled according to the ON/OFF of the power supply to control the ejection of compressed air. A driving body (not shown) is connected to the solenoid valve (10), and a hydraulic pump, an air pressure pump, an electronic pump, or the like can be used as the driving body.
The actuator (20) has a passage (21) for passing compressed air discharged from the solenoid valve (10). As shown in fig. 2, this passage is right-angled and inside a gun-shaped housing (not shown).
The actuator (20) is also provided with an air nozzle (22) connected to the solenoid valve (10) (20).
The inside of the cylinder (30) through which the compressed air passes is provided with an impact bullet (40) made of metal material and moving linearly. The invention is characterized by a structure for reducing the friction force between the impact warhead (40) and the air cylinder (30).
In order to reduce the friction force between the impact bullet (40) and the cylinder (30), the outer surface of the upper impact bullet (40) is a concave-convex surface (42).
The concave-convex surface (42) may be a spiral shape or a continuous ring-shaped structure. The concave-convex surface (42) can reduce the contact area with the inner surface of the cylinder (30) and reduce the friction force. Energy loss due to friction between the impact warhead (40) and the cylinder (30) can be reduced, and thus the reduction of the shock wave energy can be prevented.
The impact bullet (40) may be made of a material other than metal, and is characterized by a bevel (44) and a rear end groove (46).
The rear end of the cylinder (30) is provided with a magnet (24) designed for pulling the impact warhead (40) by magnetic force. The magnet (24) is mounted on the rear end portion of the cylinder (30), thereby forming an annular hole through which compressed air can pass.
A buffer member (26) is provided between the magnet (24) and the cylinder (30) to buffer noise and impact force generated by contact between the impact bullet (40) and the magnet (24).
The cushioning member (26) is characterized in that a hole for passing compressed air is formed in the cushioning member and an inclined groove (26 a) is formed in the surface of the cushioning member corresponding to the impact bullet (40).
The rear end of the impact bullet (40) is provided with a groove (46) which can be better manufactured by impact. A space (32) capable of accommodating air is formed between the buffer member (26) and the groove (46) of the impact bullet (40).
Since the space (32) for containing air is provided at the rear end of the impact bullet (40), the impact wave is generated in the external shock wave treatment apparatus, and the effect of relaxing the impact of the impact bullet (40) is maximized when the impact bullet (40) moves backward due to the reaction force. When the compressed air is discharged, the air stored in the rear end of the bullet (40) is impacted, and a stable effect is provided for the movement of the impacting bullet (40).
The cushioning member (26) is made of silicone.
The extracorporeal shock wave treatment apparatus includes a fixing member (90) for catching the shock warhead (40) returned to its original position by a reaction force after the generation of the shock wave. The fixing member (90) is mounted in the form of a ball plunger and is fitted to the inner surface of the cylinder (30).
In order to make the fixing member 90 catch the impact bullet 40 more easily, it is preferable that the front end of the impact bullet 40 is provided with a slope 44.
The impact bullet (40) is cylindrical in shape, and the inclined groove (44) can be formed by cutting off the outer surface of the leading end of the angular impact bullet (40) as shown in fig. 2.
Therefore, the inclined surface (44) is more easily caught by the fixing member (90) when the impact bullet (40) returns backward.
The position of the fixing member (90) can be set in a position where the concave-convex surface (42) of the impact bullet (40) can be easily caught. That is, the fixing member 90 may be caught by the concave-convex surface 42, instead of the fixing member 90 having to be caught by the inclined surface 44.
The impact bullet (40) can be fixed at the initial position by the fixing member (90).
After the product of the invention with the structure generates shock waves, the impact warhead (40) moves backwards due to the reaction force and compressed air outside the air cylinder (30), the electromagnetic valve (10) is automatically opened when the internal pressure reaches a certain value, and meanwhile, the compressed air at the back leaks. Then, the impact bullet (40) is fixed by the fixing member (90) and the magnet (24) fixed at the initial position.
A muffler (50) having a plurality of air slots (52) (54) is mounted to the outer surface of the cylinder (30). The muffler (50) is in contact with the outer surface of the cylinder (30) and fixes the cylinder (30), and has a cylindrical shape.
The air tanks (52, 54) are spaces for storing air, and between the muffler (50) and the air pipe (70), the outer surface of the muffler (50) is also formed.
The air grooves (52) (54) can increase the continuity of operation of the impact bullet (40) when it moves linearly in the cylinder (30) and can reduce noise.
The therapeutic apparatus of the present invention is of the type in which the impact transmitter (60) is applied to the body surface for treatment. An impedance adaptation medium may be formed between the shock transmitter (60) and the skin surface to improve the transmission of shock waves to biological tissue. For example, GEL for ultrasound.
The impact transmitter (60) is attached to the affected part and then a driving body (not shown) is operated, and compressed air is ejected from the solenoid valve (10) to move the impact bullet (40) inside the cylinder (30). The impact warhead (40) moving forward collides with the rear surface of the impact transmitter (60) to transmit the impact wave to the inside of the biological tissue of the skin.
The invention is to make a concave-convex surface (42) on the impact bullet (40), when the impact bullet (40) moves in the cylinder (30), the contact surface can be minimized, and the energy loss can be prevented.
Then, the attack force generated by the impact of the impact bullet (40) and the compressed air outside move backward. When a certain internal pressure is reached, the solenoid valve (10) is opened and compressed air is ejected to the outside, and then the impact bullet (40) is fixed at an initial position by the magnetic force of the magnet (24) and the fixing member (90).
A muffler (50) having air grooves (52, 54) is attached to the outer surface of a cylinder (30). Therefore, when the linear motion of the impact warhead (40) maintains a certain pressure, a stable shock wave can be generated.
