Through the adjustment mechanism, the positions of each impact head can be adjusted respectively. By changing the number of impact heads in the working state, the impact area and form can be adjusted. Thus, unlike the extracorporeal shock wave therapy handle used in the traditional biomedical engineering industry, it is not necessary to disassemble the original impact head and then install a new impact head to change the impact area and form, thereby greatly improving the convenience and versatility of the equipment.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] Embodiment 1: As Figures 1 to 9As shown in the figure, Embodiment 1 of the present invention provides an extracorporeal shock wave therapy handle, which mainly includes a tube body 1, a control handle 3 and a shock component 6. Among them, a gas control valve is installed in the control handle 3, and the gas control valve can adopt equipment in the prior art. The gas control valve usually has an air inlet end, an air outlet end and a control button. The air inlet end is connected with a delivery pipe 4, and the delivery pipe 4 is connected with the high-pressure gas discharge end of the extracorporeal shock wave therapy instrument. In this way, the extracorporeal shock wave therapy instrument can deliver high-pressure gas to the handle, and the high-pressure gas is discharged from the air outlet end after passing through the gas control valve. The tube body 1 is fixedly connected to the control handle 3. An air tube 2 is installed in the tube body 1, and a bullet body 5 is installed in the air tube 2. There is a gap between the bullet body 5 and the inner wall of the air tube 2, and the bullet body 5 has the freedom to slide in the air tube 2. One end of the air tube 2 is communicated with the air outlet end. Therefore, when the high-pressure gas is delivered into the air tube 2, the high-pressure gas can push the bullet body 5 to move in the air tube 2. An impact component 6 is fixed at the end of the tube body 1 far away from the control handle 3. Under the action of the high-pressure gas, the bullet body 5 impacts the impact component 6, causing the impact component 6 to generate a mechanical impact, and shock wave therapy can be performed on the patient.

[0029] As Figure 2 and Figure 8 shown in the figure, the impact component 6 includes a housing 61, an elastic body 63 and an impact body 62. Among them, the housing 61 specifically includes a connecting cylinder 611 and a cylinder cover 612. One end of the connecting cylinder 611 is threadedly connected to the tube body 1, and the other end of the connecting cylinder 611 is threadedly connected to the cylinder cover 612. The impact body 62 is located in the inner cavity formed by the cooperation of the connecting cylinder 611 and the cylinder cover 612. As Figure 2 shown in the figure, a retaining ring 6111 is fixed on the inner wall of the connecting cylinder 611 near the housing 61, and a positioning groove 6112 with a size adapted to the air tube 2 is opened on the retaining ring 6111. When the connecting cylinder 611 is threadedly installed on the tube body 1, the end of the air tube 2 is inserted into the positioning groove 6112 to limit the movement of the air tube 2. An impact port 6122 is opened on the cylinder cover 612, and at the same time, an inner cylinder 6121 is fixed on the inner side of the cylinder cover 612. The elastic body 63 is in a cylindrical shape as a whole, and the elastic body 63 is stuffed into the gap between the inner cylinder 6121 and the inner wall of the cylinder cover 612. The elastic body 63 abuts against the impact body 62 and presses the impact body 62 towards the retaining ring 6111.

[0030] After the above settings, when the bullet body 5 moves at high speed in the trachea 2, the bullet body 5 will partially pass through the retaining ring 6111 and impact the impact body 62, which enables the impact body 62 to compress the elastic body 63 and extend the end of the impact port 6122, generating an impact on the patient's body surface. A sealing ring is provided between the impact body 62 and the inner wall of the connecting cylinder 611, and an air outlet is provided beside the positioning groove 6112, and an exhaust hole is provided on the pipe body 1. After the gas in the trachea 2 is discharged from the trachea 2, it is blocked by the sealing ring and will not be discharged from the impact port 6122, but enters the gap between the pipe body 1 and the trachea 2 from the air outlet and finally is discharged from the exhaust hole. The elastic body 63 can play a buffering role on the one hand and push the impact body 62 to reset on the other hand. After the bullet body 5 impacts the impact body 62, it rebounds towards the other end of the trachea 2. When the extracorporeal shock wave therapy instrument delivers pulsed high-pressure gas into the trachea 2, the bullet body 5 reciprocates in the trachea 2 and repeatedly impacts the impact body 62, causing the impact body 62 to generate pulsed impacts to treat the patient.

[0031] As Figure 8 shown, the impact body 62 designed in the present invention includes a struck cylinder 621, an inner impact head 622 and three outer impact heads. The three outer impact heads are respectively a first outer impact head 623, a second outer impact head 624 and a third outer impact head 625. One end of the struck cylinder 621 close to the retaining ring 6111 is closed, and the other end is open. One end of the inner impact head 622 is threadedly installed in the struck cylinder 621, and the other end extends out of the impact port 6122. The outer impact heads are all cylindrical. The first outer impact head 623 is sleeved on the inner impact head 622, the second outer impact head 624 is sleeved on the first outer impact head 623, and the third outer impact head 625 is sleeved on the second outer impact head 624, forming a nested relationship in sequence.

[0032] An adjustment mechanism for adjusting the axial position of the outer impact head on the inner impact head 622 is also designed on the impact body 62. Each outer impact head has two position states. In the storage state, the whole outer impact head is located inside the housing 61 and is in the storage position; in the working state, the end of the outer impact head far from the retaining ring 6111 extends out of the impact port 6122 and is flush with the end of the inner impact head 622 extending out of the impact port 6122 under the action of the adjustment mechanism, and at this time the outer impact head is in the working position.

[0033] Each outer impact head can be adjusted individually, which endows the present invention with various impact forms. First, when all the outer impact heads are in the retracted position, only the inner impact head 622 extends out of the impact port 6122. When the bullet body 5 impacts the impact cylinder 621, the inner impact head 622 can perform shock wave treatment on the patient's body surface. When the first outer impact head 623 is in the working position, the area on the patient's body surface that can generate impacts is the overlapping area of the inner impact head 622 and the first outer impact head 623. When the second outer impact head 624 or the third outer impact head 625 is also in the working position, the actual impact area further increases. Therefore, the present invention can change the impact area by adjusting the number of outer impact heads extending out of the impact port 6122, realizing a gradual transition from a focused impact to a divergent impact. In contrast, traditional extracorporeal shock wave therapy handles need to remove the original impact head and replace it with a new one of a different size to change the impact area. Therefore, the extracorporeal shock wave therapy handle designed by the present invention has the function of quickly changing the impact area.

[0034] The present invention can also make the inner impact head 622 and the second outer impact head 624 or the third outer impact head 625 in the working state, while making the first outer impact head 623 in the retracted state, so that the impact body 62 has a columnar focused impact point and an annular divergent impact area, thereby producing a composite impact effect to a certain extent and synchronously treating lesions at different levels. Specifically, how to set the working form of the impact heads is selected by the therapist according to the actual situation.

[0035] Embodiment 2: Based on Embodiment 1, the present invention proposes Embodiment 2. In this embodiment, the adjustment mechanism designed by the present invention includes three adjustment components 7, which are respectively used to adjust the axial positions of the three outer impact heads relative to the inner impact head 622. As Figure 3 shown, each adjustment component 7 includes a first through groove 71 opened on the side wall of the connecting cylinder 611, a second through groove 72 opened on the side wall of the impact cylinder 621, and an adjustment rod 73. The first through groove 71 is opposite to the second through groove 72, and the size of the first through groove 71 is larger than that of the second through groove 72. The inner impact head 622 is provided with a receiving groove 74 and a working groove 75, and the adjustment rod 73 passes through the first through groove 71, the second through groove 72 and the side wall of the outer impact head.

[0036] When the end of the adjustment rod 73 is inserted into the receiving groove 74, the outer impact head corresponding to this adjustment rod 73 is in the retracted state, and its end does not extend out of the impact port 6122. When the adjustment rod 73 is pulled out of the receiving groove 74 and drags the outer impact head to move axially along the inner impact head 622 until the adjustment rod 73 is inserted into the working groove 75, the end of the outer impact head extends out of the impact port 6122 and is flush with the end of the inner impact head 622 extending out of the impact port 6122. At this time, this outer impact head is also in the working state.

[0037] With the above arrangement, the outer impact head can be moved on the inner impact head 622 using the adjusting rod 73, and the working state of the outer impact head can be changed by changing the plug-in relationship between the adjusting rod 73 and the receiving groove 74 or the working groove 75, thereby realizing the adjustment of the impact form.

[0038] In order to avoid interference with other external impact heads when adjusting the external impact heads, each external impact head is provided with a make way slot 76 for making way for the adjustment rods 73 on other external impact heads, so that when one of the adjustment rods 73 is adjusted individually, it will not be blocked by other external impact heads.

[0039] Embodiment three: like Figure 5 As shown, on the basis of the first and second embodiments, the present invention is to facilitate the operation of the adjustment rod 73. The present invention designs an elastic limiting mechanism on the adjustment rod 73. The elastic limiting mechanism includes a step 731 fixed on the adjustment rod 73 and a gasket 732 sleeved on the adjustment rod 73, and a spring 733 is sleeved on the adjustment rod 73 between the gasket 732 and the step 731. Among them, the step 731 is between the outer wall of the outer impact head and the inner wall of the impact tube 621, and the gasket 732 is between the step 731 and the inner wall of the impact tube 621. In this way, under the action of the spring 733, one end of the spring 733 will push the gasket 732, so that the gasket 732 is against the inner wall of the impact tube 621, and the other end will push the step 731, so that the adjustment rod 73 moves toward the inner impact head 622 as a whole, so that the end of the adjustment rod 73 can maintain the state of being inserted in the storage groove 74 or inserted in the working groove 75.

[0040] When the position of the outer impact head needs to be adjusted, it is only necessary to pull the adjusting rod 73 so that the step 731 on the adjusting rod 73 compresses the spring 733, thereby pulling the end of the adjusting rod 73 out of the receiving groove 74 or the working groove 75, and then move the adjusting rod 73 along the axial direction of the inner impact head 622 so that the adjusting rod 73 drives the outer impact head to move until the end of the adjusting rod 73 is inserted into the working groove 75 or the receiving groove 74 to complete the position adjustment.

[0041] In order to prevent the outer impact head from rotating on the inner impact head 622, thereby causing the adjustment rod 73 to be unable to accurately cooperate with the storage groove 74 or the working groove 75, a guide mechanism is designed between the inner impact head 622 and the first outer impact head 623, that is, a guide key bar is provided on the side wall of the inner impact head 622, and a guide groove that slides with the guide key bar is provided on the inner wall of the first outer impact head 623. The second outer impact head 624 and the first outer impact head 623 use a similar guide mechanism to limit the rotation of the second outer impact head 624, and similarly, a guide mechanism is also provided between the third outer impact head 625 and the second outer impact head 624.

[0042] Embodiment 4: likeFigure 10 As shown, the present invention provides an extracorporeal shock wave therapy apparatus, which uses the extracorporeal shock wave therapy handle designed in the above embodiment to perform extracorporeal shock wave therapy on patients.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
