Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a pulse balloon with capacitance and application thereof. Background Art

[0002] Aortic calcification, also known as aortic sclerosis, is the accumulation of calcium deposits on the aortic valve in the heart. Aortic calcification can have serious consequences for your health.

[0003] At present, aortic calcification is mainly treated clinically by puncturing or shattering the calcified area. For example, in the technical solution with patent number CN104582597A, multiple pulsed high-voltage electric cathodes and cathodes are distributed on the inner tube of the balloon. The pulses when the cathode and cathode discharge will drive the vibration of the electrolyte, thereby causing the inner wall of the balloon to physically vibrate. The generated physical vibration will counteract the calcified area of ​​the blood vessel to achieve the purpose of puncturing or shattering the calcified area. In the technical solution with patent number CN 109223100 A, the balloon is filled with electrolyte liquid, and the shock wave transmitter is used to discharge again, thereby driving the electrolyte liquid to vibrate, and the electrolyte liquid vibration causes the vibration of the balloon wall to achieve the purpose of shattering the calcified area. In the technical solution with patent number CN 111184553 A, the electrolyte in the balloon is also driven by shock waves to shatter the calcified area. In the technical solution with patent number CN 104519809 A, shock waves are also used to drive the electrolyte in the balloon to shatter the calcified area.

[0004] However, the shock wave balloon disclosed in the above patent generates high voltage electricity at the cathode and anode during the discharge process, and the wall thickness of the balloon is generally very thin. When the high voltage electricity is transmitted through the electrolyte, part of the high voltage electricity will break through the thin wall, and part of the high voltage electricity will appear on the outermost side of the balloon, and the high voltage electricity will act on the patient's blood vessels, thereby disturbing the heart rate, causing secondary damage to the patient, and affecting the patient's physical health.

[0044] Example

[0045] The present invention is described in detail below by way of examples. It is necessary to point out here that the following examples are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Some non-essential improvements and adjustments made by professionals and technicians in this field based on the content of the present invention above still belong to the scope of protection of the present invention.

[0046] Example 1

[0047] like Figure 1 As shown, this embodiment provides a pulse balloon with capacitor, the pulse balloon with capacitor includes a balloon 1 with a cavity inside, an inner tube 2 running through the middle of the balloon 1, a pressure divider arranged in the cavity of the balloon 1, and two high-voltage pulse power supplies installed in the cavity of the balloon 1 and located in the circumferential direction of the outer wall of the inner tube 2, the high-voltage pulse power supplies are respectively a first high-voltage pulse power supply 5 and a second high-voltage pulse power supply 6, both ends of the balloon extend outward to form an interface tube 9, both ends of the inner tube 2 extend outward and pass through the interface tube 9, and both ends of the balloon 1 are sloped at the interface tube 9, the angle of the slope is 130°, and the smoothness of the balloon in the blood vessel can be improved by the sloped setting. The pulse balloon with capacitor charges electrolyte into the cavity of the balloon through the interface tube. The voltage divider device is a capacitor bonded to the inner wall of the balloon 1 with polytetrafluoroethylene adhesive, the upper electrode 11 of the capacitor is connected to the upper side of the inner wall of the balloon 1, and the lower electrode 4 of the capacitor is connected to the lower side of the inner wall of the balloon 1. The upper electrode 11 and the lower electrode 4 are both carbon nanotube array electrodes 3. The carbon nanotube array electrode 3 of the upper electrode 11 corresponds to the carbon nanotube array electrode of the lower electrode 4 to form a capacitor, and the spacing between the carbon nanotube array electrodes is 5 nanometers.

[0048] like Figure 2 The first high-voltage pulse power supply 5 and the second high-voltage pulse power supply 6 shown in the figure both include two power supply units connected in series, and the power supply unit includes an anode layer 7, an insulating layer 10 connected to the anode layer 7, and a cathode layer 8 connected to the insulating layer 10. Before the balloon works, electrolyte is first charged into the balloon 1 until the balloon 1 is filled with electrolyte. When the cathode layer 7 and the anode layer 8 in the power supply unit release pulsed high voltage electricity, pulses will be generated. The pulses propagate through the electrolyte to drive the balloon 1 to vibrate and penetrate the calcified area of ​​the blood vessel. When discharging, most of the electrical energy is converted into mechanical energy to penetrate the calcified area of ​​the blood vessel, and the residual high voltage electricity is absorbed by the voltage divider, which avoids the conduction of high voltage electricity on the balloon surface and limits the excess high voltage electricity at the pulse source. The pulse balloon with capacitor is used in the treatment of aortic calcification.
