Description

Technical Field

[0001] This invention relates to the field of shockwave equipment technology, and more specifically, to a shockwave therapy device. Background Technology

[0002] A shockwave therapy device is a generator used to produce shockwaves. The generator contains a reciprocating bullet that strikes a treatment head at a specific frequency, generating high-energy shockwave energy, which is then focused and applied to specific parts of the body. In the medical field, shockwave generators are commonly used to treat some bone and soft tissue diseases.

[0003] Currently, shockwave therapy devices mainly use a gas filling and defilling method to power the bullet, while some use built-in electromagnets to drive the bullet's reciprocating motion. In these methods, the air in the barrel continuously exchanges with the outside air while the bullet moves. Because the bullet reciprocates at high speed in the barrel, the air in the barrel is prone to heating up. At the same time, the air in the barrel is constantly exchanging with the outside air, and the exchanged air easily carries water vapor or other impurities. As a result, after the barrel stops being used, liquefied water accumulates in the barrel due to the drop in temperature. The liquefied water and other impurities in the barrel affect the movement and service life of the bullet. In particular, the cost of treating the exchanged air in the barrel is relatively high. To solve this technical problem, a shockwave therapy device is proposed. Summary of the Invention

[0016] Beneficial effects: This application connects the internal channel and the external channel of the barrel by setting a gap at the end of the barrel. When the bullet reciprocates in the barrel, the air in the barrel is also driven to circulate back and forth. This prevents the air in the internal and external channels of the barrel from contacting the external air of the long shaft sleeve, thus preventing external air from carrying impurities that may affect the movement of the bullet. Furthermore, both the internal and external air of the barrel are dry, preventing the air inside the barrel from liquefying due to cooling after the bullet has been working in the barrel for a period of time. This prevents the impact force and service life of the bullet from being affected in subsequent use, and also reduces the noise of the bullet's movement. When the bullet reciprocates inside the barrel for a long time, the air in the channels inside and outside the barrel shaft will heat up, which in turn will increase the air pressure in the channels inside and outside the barrel shaft. By setting an expansion chamber and expansion element between the long shaft sleeve and the barrel, the air in the channels inside and outside the barrel shaft will not increase due to temperature rise, thus preventing the barrel or long shaft sleeve from deforming and not affecting the reciprocating motion of the bullet in the barrel.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0031] Reference Figures 1-10 According to one embodiment of the present invention, a shockwave therapy device includes a long shaft sleeve 1, a control component installed at one end of the long shaft sleeve 1, a treatment head installed at the other end of the long shaft sleeve 1, a gun barrel 5 installed inside the long shaft sleeve 1, and a bullet body 8 reciprocating inside the gun barrel 5. At least one electromagnet passes through the end of the gun barrel 5, wherein the electromagnet is used to drive the bullet body 8 to reciprocate, and the electromagnet is located at the end or middle of the gun barrel 5.

[0032] Both ends of the barrel 5 are provided with gaps for ventilation, and the outer side of the barrel 5 is provided with a channel for ventilation. By providing gaps at the ends of the barrel 5, the internal channel of the barrel 5 and the channel on the outer side of the shaft are connected, thereby balancing the air pressure inside the barrel 5 when the bullet reciprocates inside the barrel 5.

[0033] An expansion chamber 103 with a compensation function is also provided between the barrel 5 and the long shaft sleeve 1. The outlet of the expansion chamber 103 is provided with an expansion member 11 that balances the air pressure through structural deformation. The expansion member 11 is one of an elastic airbag, a diaphragm, or an air cushion. In this embodiment, an elastic member 9 is also installed inside the expansion chamber 103. One end of the elastic member 9 is fixed to the bottom end of the expansion chamber 103, and the other end of the elastic member 9 is fixed to the expansion member 11. In this embodiment, the elastic member 9 is preferably a spring. By setting the elastic member, the expansion member 11 moves towards the treatment head, and the initial position of the bullet body 8 is located at one end of the barrel 5 where the control device is installed.

[0034] The control device is used to control the working parameters and working state of the electromagnet, and at the same time provide initial power to the bullet body 8.

[0035] In this embodiment, when the bullet body 8 reciprocates inside the barrel 5, the air in the inner and outer channels of the barrel 5 does not come into contact with the external air of the long shaft sleeve 1. Both ends of the barrel 5 are provided with gaps for ventilation, and the outer channel of the barrel 5 is provided with a ventilation channel. By providing gaps at the ends of the barrel 5, the internal channel and the outer channel of the barrel 5 are connected. When the bullet body 8 reciprocates inside the barrel 5, the air pressure in the inner and outer channels of the barrel 5 remains in a balanced state. The air inside and outside the barrel 5 is dry air to prevent the air inside the barrel 5 from liquefying due to cooling after the bullet body 8 has been working in the barrel 5 for a period of time. This prevents the impact force and service life of the bullet body 8 from being affected in subsequent use, and also reduces the noise of the bullet body 8. When the bullet 8 reciprocates inside the barrel 5 for an extended period, the air inside and outside the barrel 5 heats up, leading to an increase in air pressure in the channels inside and outside the barrel 5. By setting an expansion cavity 103 and an expansion member 11 between the long sleeve 1 and the barrel 5, the air pressure in the channels inside and outside the barrel 5 is prevented from increasing due to temperature rise, thus preventing deformation of the barrel 5 or the long sleeve 1 and ensuring the reciprocating motion of the bullet 8 within the barrel 5. The expansion cavity 103 has a compensation function, meaning that it can achieve internal air pressure balance by supplementing air from the outside or by structural deformation. Specifically, an elastic sealing sleeve 14 is provided on the outer curved surface of the long sleeve 1, ensuring the sealing of the expansion cavity 103 while maintaining the structural strength of the barrel 5 and the long sleeve 1. The deformation resistance of the expansion member 11 is less than that of the elastic sealing sleeve 14. The expansion chamber 103 is equipped with an elastic element 9, which allows the expansion element 11 to balance the air pressure inside and outside the barrel 5 and also to stop the moving bullet 8 from moving to its initial position. The expansion element 11 and the long shaft sleeve 1 are detachably connected, making the expansion element 11 easy to replace. The expansion element 11 in this embodiment has high sealing performance. Example 2

[0036] Reference Figures 1-10 The difference between this embodiment and Embodiment 1 is that the treatment head includes a second outer bushing 3 and an impact head 4 installed inside the second outer bushing 3, as well as a second inner bushing 13 fixed to one end of the second outer bushing 3.

[0037] The other end of the second inner bushing 13 is installed at the end of the long bushing 1, wherein the second inner bushing 13 and the long bushing 1 are detachably connected. By installing the second inner bushing 13 between the long bushing 1 and the second outer bushing 3, the end of the second outer bushing 3 abuts against the long bushing 1. In this embodiment, the detachable second inner bushing 13 makes the expansion member 11 easy to maintain, and at the same time fixes the end of the barrel 5.

[0038] The second outer bushing 3 and the second inner bushing 13 are detachably connected. In this embodiment, it is preferred that the end of the second inner bushing 13 and the interior of the second outer bushing 3 are connected by threads, but it is not limited to the end of the second inner bushing 13 and the interior of the second outer bushing 3 being connected only by threads. The second inner bushing 13 and the second outer bushing 3 are snapped together or abutted against each other. When the second inner bushing 13 and the second outer bushing 3 abut against each other, the second outer bushing 3 is fixed on the curved surface of the long bushing 1.

[0039] One end of the impact head 4 is placed in the second inner bushing 13, wherein the impact head 4 and the bullet body 8 collide with each other to generate a shock wave;

[0040] The second inner bushing 13 is further provided with an annular retaining plate 134. The annular retaining plate 134 has a second through hole 130 in the middle for fixing one end of the barrel 5, and the gap at one end of the barrel 5 is set between the impact head 4 and the barrel 5. The barrel 5 has a fourth channel 50 inside. In this embodiment, it is preferred that the second through hole 130 is provided with a stepped second protrusion 1301, wherein the number of the second protrusion 1301 is at least two, and the second protrusion 1301 and the annular retaining plate 134 are integrally connected, so that the radial end face of the second protrusion 1301 abuts against the end of the barrel 5, and the outer curved surface of the barrel 5 also abuts against the inner wall of the second protrusion 1301, thereby limiting one end of the barrel 5. By setting the second protrusion 1301, a gap is formed between the end of the barrel 5 and the impact head 4, thereby allowing the second through hole 130 to connect the inner and outer channels of the barrel 5.

[0041] When there are two second protrusions 1301, the second protrusions 1301 are symmetrically distributed, and the two second protrusions 1301 face each other in a straight or arc-shaped manner; when there are more than two second protrusions 1301, the second protrusions 1301 are distributed in a circumferential array, and the faces of the second protrusions 1301 facing the center of the circle are straight or arc-shaped; in this embodiment, the diameter of the second through hole 130 is larger than the outer diameter of the gun barrel 5, so that the second through hole 130 and the fourth channel 50 are interconnected.

[0042] The electromagnet has a ring structure and includes a first electromagnet 71 that passes through one end of the gun barrel 5.

[0043] The first electromagnet 71 is fixed inside the second inner bushing 13, and the outer curved surface of the first electromagnet 71 abuts against the inner wall of the second inner bushing 13. One end of the first electromagnet 71 also abuts against the annular plate 134.

[0044] The inner diameter of the first electromagnet 71 is larger than the outer diameter of the gun barrel 5, so that a fifth channel 710 is formed between the first electromagnet 71 and the gun barrel 5, and the fourth channel 50 is connected to the fifth channel 710 through the second through hole 130; in this embodiment, it is preferred that the outer diameter of the second through hole 130 is not larger than the outer diameter of the fifth channel 710.

[0045] The end of the second inner bushing 13 is also fitted with a third inner bushing 131, wherein the third inner bushing 131 is used to abut against the end of the first electromagnet 71, so that the first electromagnet 71 is fixed in the second inner bushing 13.

[0046] The inner diameter of the third inner bushing 131 is larger than the outer diameter of the barrel 5, so that a third channel 1310 is formed between the third inner bushing 131 and the barrel 5.

[0047] The third channel 1310 and the fifth channel 710 are interconnected; in this embodiment, it is preferred that the outer diameter of the fifth channel 710 is not greater than the outer diameter of the third channel 1310.

[0048] A first channel 101 and a second channel 102 are also provided between the gun barrel 5 and the long shaft sleeve 1, wherein the radial dimension of the second channel 102 is larger than the radial dimension of the first channel 101.

[0049] The third channel 1310, the second channel 102, and the first channel 101 are sequentially connected. In this embodiment, the outer diameter of the third channel 1310 is not greater than the outer diameter of the second channel 102, so that the air flows sequentially from the fourth channel 50 to the second through hole 130, the fifth channel 710, the third channel 1310, and the second channel 102. When the air in the fourth channel 50 heats up and expands, the expansion member 11 reduces the impact of the air heating on the movement of the bullet body 8 by compressing the space of the expansion cavity 103.

[0050] In this embodiment, the radial dimension of the expansion cavity 103 is larger than the radial dimension of the first channel 101, thereby increasing the force-bearing area of ​​the expansion member 11.

[0051] The end of the long shaft sleeve 1 is also equipped with a first inner shaft sleeve 12, wherein the first inner shaft sleeve 12 and the long shaft sleeve 1 are detachably connected.

[0052] The first inner bushing 12 is provided with a first through hole 120 in the middle. The first through hole 120 is used to fix the other end of the gun barrel 5 and to make the gap of the other end of the gun barrel 5 between the impact head 4 and the gun barrel 5. In this embodiment, it is preferred that the first through hole 120 is provided with a stepped first protrusion 1201, and the number of the first protrusion 1201 is at least 2. The first protrusion 1201 and the first inner bushing 12 are integrally connected, so that the radial end face of the first protrusion 1201 abuts against the end of the gun barrel 5, and the outer curved surface of the gun barrel 5 abuts against the inner wall of the first protrusion 1201.

[0053] The diameter of the first through hole 120 is larger than the outer diameter of the barrel 5, so that the fourth channel 50 is connected to the first channel 101 through the first through hole 120; in this embodiment, the barrel 5 is fixed in the middle of the long sleeve 1 by installing the first inner bushing 12 and the second inner bushing 13 at both ends of the barrel 5 respectively.

[0054] The outer diameter of the first through hole 120 is not greater than the outer diameter of the first channel 101; in this embodiment, the first channel 101, the second channel 102, the third channel 1310, the fourth channel 50, and the fifth channel 710 are all part of a channel, that is, the channel includes the first channel 101, the second channel 102, the third channel 1310, the fourth channel 50, and the fifth channel 710;

[0055] The opening of the expansion cavity 103 faces the first inner bushing 12, and the second channel 102 is located between the expansion cavity 103 and the first inner bushing 12.

[0056] The opening of the expansion cavity 103 is an arc-shaped structure or an annular structure, and the number of expansion cavities 103 is at least one.

[0057] In this embodiment, by setting gaps at both ends of the barrel 5 for ventilation, the air in the fourth channel 50 is interconnected with the first channel 101, the second channel 102, the third channel 1310, and the fifth channel 710 outside the barrel 5. As a result, the bullet body 8 does not need to be replenished with external air to reciprocate inside the fourth channel 50. The bullet body 8 is continuously driven to reciprocate by the first electromagnet 71, but the initial drive of the bullet body 8 is driven by the control component. In this embodiment, the second channel 102 has the largest diameter, which facilitates the maintenance of the expansion component 11 in the expansion chamber and also allows the air pressure in the channel outside the barrel 5 to quickly balance the temperature. Example 3

[0058] Reference Figures 1-10 The difference between this embodiment and embodiment three is that the electromagnet also includes a second electromagnet 72. The second electromagnet 72 is installed inside the long shaft sleeve 1, and one end of the second electromagnet 72 abuts against the radial end face of the long shaft sleeve 1, wherein the outer curved surface of the second electromagnet 72 also abuts against the inner wall of the long shaft sleeve 1.

[0059] The other end of the second electromagnet 72 abuts against the first inner bushing 12;

[0060] The inner diameter of the second electromagnet 72 is larger than the outer diameter of the gun barrel 5, so that a sixth channel 720 is formed between the second electromagnet 72 and the gun barrel 5, and the fourth channel 50 is connected to the sixth channel 720 through the first through hole 120; in this embodiment, the outer diameter of the sixth channel 720 is not larger than the outer diameter of the first channel 101.

[0061] The sixth channel 720 and the first channel 101 are interconnected. In this embodiment, the channel also includes the sixth channel 720.

[0062] In this embodiment, gaps for ventilation are provided at both ends of the barrel 5 to connect the air in the fourth channel with the first channel 101, second channel 102, third channel 1310, fifth channel 710, and sixth channel 720 on the outside of the barrel 5. This allows the air inside the fourth channel 50 to circulate back and forth as the bullet 8 reciprocates. The addition of a second electromagnet 72 increases the length of the long shaft sleeve 1, ensuring the impact strength of the bullet 8 during reciprocating motion. Electromagnets are installed at both ends of the barrel 5. When the first electromagnet 71 provides velocity to the bullet 8, the second electromagnet 72 can apply external force to further increase or decrease the speed of the bullet 8, thus controlling the impact strength. The inner diameters of both the first and second electromagnets 71 and 72 are larger than the outer diameter of the barrel 5, ensuring that the reciprocating motion of the bullet 8 does not affect the airflow inside and outside the barrel 5. Example 4

[0063] Reference Figures 1-10 The difference between this embodiment and embodiment two is that a second sealing ring 62 is installed on the end of the second inner bushing 13, wherein the end of the impact head 4 passes through the second sealing ring 62, and one end of the impact head 4 is inserted into the second inner bushing 13; the second sealing ring 62 in this embodiment is used to improve the sealing between the impact head 4 and the second inner bushing 13.

[0064] The impact head 4 has a conical protrusion on its curved surface, and the conical protrusion abuts against the first sealing ring 61. The first sealing ring 61 has a conical cross-section along the central axis.

[0065] The first sealing ring 61 is fixed in the second outer bushing 3 by embedding.
