Description

Electrode selection device for cardiovascular stenosis

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to an electrode selection device for cardiovascular stenosis.

Background

The blood vessel stenosis refers to the condition that lipid in blood is deposited on an original smooth blood vessel intima due to abnormal lipid metabolism of human artery and vein blood vessels, including coronary vessels, peripheral vessels, intracranial vessels and the like, lipid plaques of atheroma are gradually accumulated, and the plaques are increased and even calcified to cause the stenosis of the blood vessel cavity along with the time, so that the blood flow is blocked, the blood vessel and the organism at the downstream are ischemic, and the corresponding clinical manifestation is generated. If the stenosis occurs in coronary artery, palpitation, chest pain, dyspnea and angina can be caused, and serious patients can cause insufficient blood supply to cardiac muscle or cardiac muscle necrosis; if it occurs peripherally, a decrease in skin epidermal temperature, muscle atrophy, intermittent claudication and even necrosis or amputation of the distal limb may occur. If it occurs in the cranium, dizziness, syncope, brain tissue damage and brain dysfunction may occur.

With the development of cardiovascular intervention technology, the technology aiming at angiostenosis lesion is gradually diversified; for the lesion with higher stenosis degree and serious calcification, the existing technology is to firstly pass through a lesion blood vessel by a guide wire, then place a high-pressure balloon at the stenosis position for pre-expansion, and finally implant a vascular stent at the target stenosis position by exchanging a stent delivery system. The technology also has many problems at present, 10-15 atmospheres are sometimes needed for pre-expanding the blood vessel for the pathological changes with serious calcification, and 30 atmospheres are sometimes needed, and the result brought by the high pressure inevitably causes the calcified plaque to transfer stress to the inner wall of the blood vessel to cause blood vessel damage, and serious patients cause blood vessel interlayer or perforation. In addition, clinical studies have shown that the long-term restenosis rate of the lesions after the stent has been successfully implanted is high, because the stent is a foreign substance, and the continuous stimulation of the vascular intima can cause intimal hyperplasia, and further restenosis of the blood vessel occurs.

Chinese patent CN111568500A discloses a blood vessel recanalization system for angiostenosis pathological change, including sacculus, energy generation controller, pipe, the pipe includes the main part pipe, pipe one end with the energy generation controller is connected, the main part pipe of the pipe other end with the one end of sacculus is connected, the sacculus includes sacculus main part, inner tube, electrode pair, affiliated energy generation controller can send and regulate and control specific frequency's shock signal and make the electrode pair produce and vibrate, can solve the vascular damage that current cardiovascular intervention technique caused through simple high pressure sacculus pre-dilation to this application has the medicine carrying function, and this medicine can restrain the blood vessel recanalization membrane increase after the recanalization, avoids causing the restenosis condition after the recanalization to appear. However, the pulse parameter setting in the energy generation controller used in the application is single, the pulse release energy cannot be controlled, the continuous adjustment of pulse voltage cannot be realized, multiple pulses are independently and continuously released for a serious area, the functions are few, and the effect of the system on lesion treatment is weakened.
