[0035] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0036] Please refer to Figures 1 to 4 As shown in the embodiments of this utility model,

[0037] A portable miniaturized shockwave balloon catheter includes a shockwave balloon catheter body 1 and a shockwave therapy host 2;

[0038] The shockwave balloon catheter body 1 includes a sheath 101, a balloon 102 is provided at one end of the sheath 101, a metal wire 103 is provided inside the sheath 101, an electrode pair 104 is electrically connected at one end of the metal wire 103, an anti-dislodgement mechanism 4 is located inside the balloon 102, and an injection port 105 is provided at the end of the sheath 101 away from the balloon 102.

[0039] One end of the metal wire 103 is electrically connected to the power supply interface of the shock wave therapy host 2 via a conductive plug.

[0040] By adopting the above technical solution, the shockwave balloon catheter body 1 is inserted into the patient's lesion, and then filling fluid is injected into the balloon 102 through the injection port 105, causing the balloon 102 to collide. Then, the switch of the shockwave therapy host 2 is turned on, at which time the electrode pair 104 is energized, and high-voltage pulses are emitted to bombard the lesion to achieve the therapeutic purpose.

[0041] In this embodiment, the power supply structure of the shockwave therapy host 2 is provided with an anti-disconnection mechanism 4 to prevent the conductive plug from separating from the power supply interface;

[0042] The anti-detachment mechanism 4 includes an angle iron 401 and an anti-detachment plate 402. The angle iron 401 is fixed to one side of the shockwave therapy host 2. In this embodiment, the angle iron 401 is fixed to one side of the shockwave therapy host 2 by screws. The anti-detachment plate 402 is connected to the angle iron 401 by a height adjustment component. The anti-detachment plate 402 is located on the side of the power supply interface of the shockwave therapy host 2. The bottom of the anti-detachment plate 402 is provided with a wire groove 403 for the wire of the conductive plug to pass through. The height adjustment component includes a pull rod 404. The bottom of the pull rod 404 is fixedly connected to the top of the anti-detachment plate 402. The upper end of the pull rod 404 slides through the angle iron 401 and is fixedly connected to a limit block 405. In order to facilitate lifting the limit block 405, a handle 406 is fixedly connected to the top of the limit block 405.

[0043] By adopting the above technical solution, when using the device, first pull up the limiting block 405 so that the anti-detachment plate 402 moves above the power supply interface of the shockwave therapy host 2. Then, insert the conductive plug of the shockwave balloon catheter body 1 into the power supply interface of the shockwave therapy host 2. At this time, release the limiting block 405, and the anti-detachment plate 402 will automatically fall down under the action of gravity to limit the conductive plug of the shockwave balloon catheter body 1.

[0044] In this embodiment, a guide rod 407 is fixedly connected to the upper end of the anti-detachment plate 402. The upper end of the guide rod 407 slides through the angle iron 401. This arrangement prevents the anti-detachment plate 402 from rotating due to external vibration.

[0045] In this embodiment, a spring 408 is sleeved on the guide rod 407. The bottom of the spring 408 presses on the anti-detachment plate 402, and the top of the spring 408 abuts against the bottom of the angle iron 401. The spring 408 can compress the anti-detachment plate 402 to a certain extent to prevent the anti-detachment plate 402 from moving upward easily.

[0046] In this embodiment, an inverted L-shaped block 3 is detachably installed on the top of the shockwave therapy host 2. In this embodiment, a mounting plate 303 is fixedly connected to the bottom of the inverted L-shaped block 3, and the mounting plate 303 is fixed to the top of the shockwave therapy host 2 by screws; this setting reduces the modification cost.

[0047] The top of the inverted L-shaped block 3 is provided with a handle 302. The handle 302 makes it easy for medical staff to lift and carry the shockwave therapy host 2, making the shockwave therapy host 2 easy to carry.

[0048] The upper end of the inverted L-shaped block 3 is provided with a locking component for fixing the shockwave therapy host 2. In this embodiment, the locking component includes a mounting slot 301, which is located at the bottom of the upper end of the inverted L-shaped block 3. The inverted L-shaped block 3 can be hung on the operating table frame through the mounting slot 301. A handle bolt 304 for fixing the inverted L-shaped block 3 to the operating table frame is threaded on one side of the inverted L-shaped block 3. With the above configuration, when it is necessary to fix the shockwave therapy host 2, the inverted L-shaped block 3 is hung on the operating table frame through the mounting slot 301, and then the handle bolt 304 is tightened so that one end of the handle bolt 304 abuts against one side of the operating table frame, thereby firmly fixing the inverted L-shaped block 3 to the operating table frame, thus achieving quick locking of the shockwave therapy host 2.

[0049] To ensure the stability of the shockwave therapy host 2, the inner wall of the mounting slot 301 is provided with anti-slip texture.
