Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, to an adjustable electrode device for an intravascular shockwave therapy device. Background Technology

[0002] Vascular stenosis rarely resolves on its own and requires treatment to prevent further narrowing or to relieve the stenosis. If calcification occurs in blood vessels, they become more fragile than normal, increasing the risk of rupture. If calcification and significant narrowing occur in the cardiovascular and cerebrovascular systems, it can potentially impact lifespan.

[0003] In treating vascular lesions, existing treatment methods deliver a shockwave balloon to the lesion, causing the electrode assembly inside the balloon to generate shockwaves, thereby breaking up the calcifications in the lesion area. However, the position of the electrode assembly inside the balloon is usually fixed. To increase the impact range of the electrode assembly inside the balloon, multiple sets of equally spaced electrode assemblies are usually placed inside the balloon. However, due to the limited space inside the balloon catheter, multiple sets of electrode assemblies are connected to leads, and a certain number of leads need to pass through the catheter, which can easily lead to lead misalignment. To address this, we propose an adjustable electrode device for intravascular shockwave therapy. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this application provides an adjustable electrode device for an intravascular shockwave therapy device, which can solve the problem that the electrode assembly inside the balloon cannot be moved.

[0005] The technical solution adopted by this application embodiment to solve its technical problem is: an adjustable electrode device for an intravascular shockwave therapy device, including a thiopancreatography (THB) tube, a catheter sleeved on the THB tube, a first electrode assembly installed on the THB tube, and a second electrode assembly slidably sleeved on the THB tube, the first electrode assembly and the second electrode assembly being wired together and connected by a spring wire, a balloon being provided on the catheter, and the first electrode assembly and the second electrode assembly being connected to the shockwave therapy device.

[0006] In one specific implementation, there is a gap between the catheter and the thiopancreatography tube, and one end of the second electrode assembly is connected to a traction wire, which passes through the gap.

[0007] In one specific implementation, the first electrode assembly includes a first inner electrode, which is fixedly sleeved on the sodium hypochlorite tube. A first insulating sleeve is sleeved on the first inner electrode, and a first outer electrode is sleeved on the first insulating sleeve. One end of the first inner electrode is connected to a first wire.

[0008] In one specific implementation, a first energy outlet is provided on the first external electrode, and a second energy outlet is provided on the first insulating sleeve, with the first energy outlet and the second energy outlet being configured correspondingly.

[0009] In one specific implementation, the second electrode assembly includes a second inner electrode slidably sleeved on the sodium hypochlorite tube, a second insulating sleeve sleeved on the second inner electrode, a second outer electrode sleeved on the second insulating sleeve, and a second wire connected to one end of the second inner electrode.

[0010] In one specific implementation, a third energy outlet is provided on the second external electrode, and a fourth energy outlet is provided on the second insulating sleeve, with the third energy outlet and the fourth energy outlet being configured correspondingly.

[0011] In one specific implementation, the first external electrode and the second external electrode are connected by the same third wire, and one end of the second external electrode is connected to a fourth wire. The first wire, the second wire, and the fourth wire pass through a gap and are connected to the shock wave therapy device.

[0012] In one specific implementation, the spring wire is slidably sleeved on the sodium hypochlorite tube, and its two ends are fixedly connected to the first insulating sleeve and the second insulating sleeve, respectively.

[0013] The advantages of this embodiment are: by sleeved a catheter on the thiospherical tube, and simultaneously fixedly sleeved a first electrode assembly on the thiospherical tube, and slidably sleeved a second electrode assembly, a spring is connected between the first electrode assembly and the second electrode assembly. In addition, one end of the second electrode assembly is connected to a traction wire, which passes through the catheter. Thus, by pulling the traction wire, the second electrode assembly can be moved on the catheter, thereby achieving the purpose of fine-tuning the position of the second electrode assembly, and further achieving the adjustment of the shock wave impact range, which is helpful for the treatment of intravascular calcification lesions. By setting the spring wire, the second electrode assembly can be automatically reset when the traction wire is not pulled. Attached Figure Description

Detailed Implementation

[0020] The technical solution in this application embodiment is to solve the problem that the electrode assembly inside the balloon 60 cannot move. The general idea is as follows:

[0021] Example:

[0022] Please see Figure 1-5 An adjustable electrode device for intravascular shockwave therapy includes a thiopancreatography (ThioP) tube 10, a catheter 20 sleeved on the thioP 10, a first electrode assembly 30 mounted on the thioP 10, and a second electrode assembly 40 slidably sleeved on the thioP 10. The first electrode assembly 30 and the second electrode assembly 40 are electrically connected and connected by a spring wire 50. A balloon 60 is disposed on the catheter 20. The first electrode assembly 30 and the second electrode assembly 40 are connected to the shockwave therapy device. Specifically, the first electrode assembly 30 and the second electrode assembly 40 are connected to the shockwave therapy device to provide power to the first electrode assembly 30 and the second electrode assembly 40. The balloon 60... The catheter 20 is connected to an existing injection device to inject gas and electrolyte into the balloon 60. Under the control of the shockwave therapy device host, the first electrode assembly 30 and the second electrode assembly 40 release shockwaves to treat intravascular calcified lesions. Furthermore, there is a gap between the catheter 20 and the hypotube 10. One end of the second electrode assembly 40 is connected to a traction wire 80, which passes through the gap and the catheter 20. Pulling the traction wire 80 allows the second electrode assembly 40 to move on the hypotube 10, thereby fine-tuning the position of the second electrode assembly 40 and adjusting the shockwave range.

[0023] See Figure 2-4The first electrode assembly 30 includes a first inner electrode 310, which is fixedly sleeved on the sodium hypochlorite tube 10. A first insulating sleeve 320 is sleeved on the first inner electrode 310, and a first outer electrode 330 is sleeved on the first insulating sleeve 320. The first insulating sleeve 320 separates the first inner electrode 310 and the first outer electrode 330. One end of the first inner electrode 310 is connected to a first wire 340. A first energy outlet is formed on the first outer electrode 330, and a second energy outlet is formed on the first insulating sleeve 320. The first energy outlet and the second energy outlet are correspondingly arranged. The second electrode assembly 40 includes a second inner electrode 410 slidably sleeved on the sodium hypochlorite tube 10. A second insulating sleeve 420 is provided on the upper part, and a second outer electrode 430 is provided on the second insulating sleeve 420. The second insulating sleeve 420 separates the second inner electrode 410 and the second outer electrode 430. It should be noted that the thickness of the first inner electrode 310 and the second inner electrode 410 is 0.08 mm-0.12 mm, the thickness of the first outer electrode 330 and the second outer electrode 430 is 0.05 mm-0.1 mm, and the diameter of the spring wire 50 is 0.08 mm. One end of the second inner electrode 410 is connected to a second wire 440. A third energy outlet is provided on the second outer electrode 430, and a fourth energy outlet is provided on the second insulating sleeve 420. The third energy outlet and the fourth energy outlet are arranged correspondingly.

[0024] See Figure 2-4 The first external electrode 330 and the second external electrode 430 are connected by the same third wire 70, and one end of the second external electrode 430 is connected to a fourth wire 710. The first wire 340, the second wire 440 and the fourth wire 710 pass through the gap and are connected to the shock wave therapy device. Specifically, the third wire 70 has a certain length so that the second electrode assembly 40 can move on the catheter 20.

[0025] See Figure 5 The spring wire 50 is slidably sleeved on the hysteresis tube 10, and its two ends are fixedly connected to the first insulating sleeve 320 and the second insulating sleeve 420 respectively. The traction wire 80 is made of insulating material, and the opposing ends of the first insulating sleeve 320 and the second insulating sleeve 420 are fixedly connected to insulating rings. The two ends of the spring wire 50 are fixedly connected to the insulating rings on both sides.

[0026] When this application is used:

[0027] When the balloon 60 reaches the lesion area, electrolyte can be filled into the balloon 60 to activate the first electrode assembly 30 and the second electrode assembly 40, generating shock waves to treat the lesion area. By pulling the traction wire 80, the second electrode assembly 40 can be moved on the sodium hypochlorite tube 10, thereby fine-tuning the position of the second electrode assembly 40 and thus fine-tuning the range of the shock waves, which helps to break up calcifications in the lesion area.

[0028] It should be noted that the specific model and specifications of the first electrode assembly 30 and the second electrode assembly 40 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0029] The power supply and principle of the first electrode assembly 30 and the second electrode assembly 40 are clear to those skilled in the art and will not be described in detail here.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
