[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1:

[0051] like Figures 1 to 9 As shown, Embodiment 1 of the present invention provides an extracorporeal shock wave therapy handle, mainly comprising a tube body 1, a control handle 3, and an impact assembly 6. The control handle 3 is equipped with a gas control valve, which can be a device from the prior art. The gas control valve typically has an inlet end, an outlet end, and a control button. The inlet end is connected to a delivery pipe 4, which is connected to the high-pressure gas outlet end of the extracorporeal shock wave therapy device. This allows the extracorporeal shock wave therapy device to deliver high-pressure gas to the handle. The high-pressure gas passes through the gas control valve and exits from the outlet end. The tube body 1 is fixedly connected to the control handle 3. An air tube 2 is installed inside the tube body 1, and a projectile 5 is installed inside the air tube 2. A gap is left between the projectile 5 and the inner wall of the air tube 2, allowing the projectile 5 to slide freely within the air tube 2. One end of the air tube 2 is connected to the outlet end; therefore, when high-pressure gas is delivered to the air tube 2, the high-pressure gas can push the projectile 5 to move within the air tube 2. The impact assembly 6 is fixed to the end of the tube body 1 away from the control handle 3. Under the action of high-pressure gas, the bullet body 5 impacts the impact component 6, causing the impact component 6 to generate mechanical impact, which can provide shock wave therapy to the patient.

[0052] like Figure 2 and Figure 8As shown, the impact assembly 6 comprises a cover 61, an elastic body 63 and an impact body 62. The cover 61 specifically comprises a connecting cylinder 611 and a cylinder cover 612. One end of the connecting cylinder 611 is threadedly connected with the pipe body 1, and the other end of the connecting cylinder 611 is threadedly connected with 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 shown Figure 2 As shown, the connecting cylinder 611 is fixed with a check ring 6111 on the inner wall of one end of the cover 61, and the check ring 6111 is provided with a positioning groove 6112 with a size matched with the gas pipe 2. When the connecting cylinder 611 is threadedly installed on the pipe body 1, the end of the gas pipe 2 is inserted into the positioning groove 6112, thereby limiting the movement of the gas pipe 2. The cylinder cover 612 is provided with an impact port 6122, and the inner side of the cylinder cover 612 is fixed with an inner cylinder 6121. The elastic body 63 is in a tubular shape, and is inserted 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 extrudes the impact body 62 towards the check ring 6111.

[0053] Through the above arrangement, when the bullet body 5 moves at high speed in the gas pipe 2, the bullet body 5 will partially pass through the check 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 to impact the body surface of the patient. A sealing ring is arranged between the impact body 62 and the inner wall of the connecting cylinder 611, and a gas outlet is arranged beside the positioning groove 6112. An exhaust hole is arranged on the pipe body 1. After the gas in the gas pipe 2 is discharged from the gas pipe 2, it is blocked by the sealing ring and cannot be discharged from the impact port 6122, but enters the gap between the pipe body 1 and the gas pipe 2 from the gas outlet, and is finally discharged from the exhaust hole. The elastic body 63 can play a buffering role on the one hand and can 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 gas pipe 2. When the extracorporeal shock wave therapy instrument delivers pulsed high-pressure gas into the gas pipe 2, the bullet body 5 reciprocally moves in the gas pipe 2 and repeatedly impacts the impact body 62, so that the impact body 62 generates pulsed impact to treat the patient.

[0054] As shown, Figure 8 The impact body 62 designed by the present application comprises a hit cylinder 621, an inner impact head 622 and three outer impact heads. The three outer impact heads are a first outer impact head 623, a second outer impact head 624 and a third outer impact head 625. The hit cylinder 621 is closed at one end close to the check ring 6111 and is open at the other end. One end of the inner impact head 622 is threadedly installed in the hit cylinder 621, and the other end extends out of the impact port 6122. The outer impact heads are all in a tubular shape. 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.

[0055] The impact body 62 is further provided with an adjusting mechanism for adjusting the axial position of the outer impact head relative to the inner impact head 622. Each outer impact head has two position states. In the storage state, the outer impact head is located in the housing 61 and is in the storage position. In the working state, the outer impact head extends out of the impact port 6122 under the action of the adjusting mechanism and is flush with the end of the inner impact head 622 extending out of the impact port 6122, and at this time, the outer impact head is in the working position.

[0056] Each outer impact head can be adjusted individually, which makes the present application have multiple impact forms. First, when all the outer impact heads are in the storage position, only the inner impact head 622 extends out of the impact port 6122, and when the bullet body 5 impacts the impact cylinder 621, the inner impact head 622 can perform shock wave treatment on the body surface of the patient. When the first outer impact head 623 is in the working position, the area of the patient's body surface that is impacted is the superimposed 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 is further increased. Therefore, the present application can change the impact area by adjusting the number of outer impact heads extending out of the impact port 6122, and realize the gradual transition from focused impact to divergent impact. The conventional extracorporeal shock wave treatment handle needs to be disassembled and replaced with a new impact head of different size to change the impact area. Therefore, the extracorporeal shock wave treatment handle designed in the present application has the function of quickly changing the impact area.

[0057] The present application can also make the inner impact head 622 and the second outer impact head 624 or the third outer impact head 625 be in the working state, and the first outer impact head 623 be in the storage state, so that the impact body 62 has a columnar focused impact point and a ring-shaped divergent impact area, thereby producing a composite impact effect to a certain extent and synchronously processing different levels of lesions. The specific working form of the impact head is selected by the therapist according to the actual situation.

[0058] Embodiment two

[0059] On the basis of embodiment one, the present application proposes embodiment two. In this embodiment two, the adjusting mechanism designed in the present application includes three adjusting assemblies 7 for adjusting the axial position of the three outer impact heads relative to the inner impact head 622. Figure 3 As shown in the figure, each adjusting assembly 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 adjusting 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 storage groove 74 and a working groove 75, and the adjusting rod 73 passes through the first through groove 71, the second through groove 72 and the side wall of the outer impact head.

[0060] When the end of the adjusting rod 73 is inserted into the receiving slot 74, the outer impact head corresponding to the adjusting rod 73 is in a receiving state, and its end does not protrude from the impact port 6122; when the adjusting rod 73 is pulled out of the receiving slot 74 and drags the outer impact head along the axial direction of the inner impact head 622 until the adjusting rod 73 is inserted into the working slot 75, the end of the outer impact head protrudes from the impact port 6122 and is flush with the end of the inner impact head 622 that protrudes from the impact port 6122, at which time the outer impact head is also in a working state.

[0061] With the above settings, the outer impact head can be moved on the inner impact head 622 by adjusting the rod 73, and the working state of the outer impact head can be changed by changing the connection between the adjusting rod 73 and the receiving groove 74 or the working groove 75, thereby adjusting the impact mode.

[0062] In order to avoid interference with other external impact heads when adjusting the external impact head, each external impact head is provided with a clearance groove 76 to make way for the adjustment rod 73 of other external impact heads. In this way, when adjusting one of the adjustment rods 73 individually, it will not be blocked by other external impact heads.

[0063] Example 3:

[0064] like Figure 5 As shown, based on Embodiments 1 and 2, this invention, to facilitate the operation of the adjusting rod 73, incorporates an elastic limiting mechanism on the adjusting rod 73. The elastic limiting mechanism includes a step 731 fixed to the adjusting rod 73 and a washer 732 sleeved on the adjusting rod 73. A spring 733 is sleeved on the adjusting rod 73 between the washer 732 and the step 731. The step 731 is located between the outer wall of the outer impact head and the inner wall of the impact cylinder 621, while the washer 732 is located between the step 731 and the inner wall of the impact cylinder 621. Thus, under the action of the spring 733, one end of the spring 733 pushes the washer 732, causing it to press against the inner wall of the impact cylinder 621, while the other end pushes the step 731, causing the adjusting rod 73 to move inward toward the impact head 622. This allows the end of the adjusting rod 73 to remain inserted in the receiving slot 74 or the working slot 75.

[0065] When the position of the outer impact head needs to be adjusted, simply pull the adjusting rod 73 to compress the spring 733 on the step 731 of the adjusting rod 73, thereby pulling the end of the adjusting rod 73 out of the receiving groove 74 or the working groove 75. Then, move the adjusting rod 73 along the axial direction of the inner impact head 622 to move the outer impact head until the end of the adjusting rod 73 is inserted into the working groove 75 or the receiving groove 74, thus completing the position adjustment.

[0066] In order to avoid the outer impact head rotating on the inner impact head 622, thus causing the adjusting rod 73 unable to accurately match the receiving groove 74 or the working groove 75, a guiding mechanism is designed between the inner impact head 622 and the first outer impact head 623, that is, a guiding key strip is arranged on the side wall of the inner impact head 622, and a guiding groove which is in sliding cooperation with the guiding key strip is arranged on the inner wall of the first outer impact head 623. The second outer impact head 624 and the first outer impact head 623 adopt similar guiding mechanism to limit the rotation of the second outer impact head 624, and the third outer impact head 625 and the second outer impact head 624 also have a guiding mechanism arranged therebetween.

[0067] Embodiment four:

[0068] As shown in Figure 10 the present application provides an extracorporeal shock wave therapy instrument which adopts the extracorporeal shock wave therapy handle designed in the above embodiments to perform extracorporeal shock wave therapy on patients.

[0069] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
