Problems solved by technology

However, the cost of this kind of coil embolization material is high, and the current application in my country is still dominated by imported materials. On average, each case of aneurysm needs 5-7 coils, and the cost of interventional treatment is more than 100,000 yuan. 2-3 times, causing a heavy economic burden to the family and society

Embodiment 1

[0017] like figure 1 As shown, a multi-point electrolysis system for releasing intracranial aneurysm intervention embolic materials includes a coil 3 and a coil delivery system, and the coil 3 includes a plurality of small coils connected end to end and connecting small springs The release point 4 of the coil, the shapes of multiple small coils are different, the release point 4 is connected between the small coils, and the release point 4 can be disconnected when it is powered on; the coil delivery system includes a delivery guide wire 5 and a microcatheter 6 , the delivery guidewire 5 is placed inside the microcatheter 6, the front end of the delivery guidewire 5 is connected to the tail end of the coil 3 through the release point 4, the front end of the microcatheter 6 is warped into the aneurysm, and the front end of the microcatheter 6 is provided with an electrified wire 7. The wall of the microcatheter 6 is provided with a micro wire, and the micro wire is connected wit...

Embodiment 2

[0020] The present invention also discloses a detachment method based on the above-mentioned multi-point electrolysis system, the method includes the following steps: S01, putting the matched microcatheter 6 with the energized wire 7 into the parent artery 2 and transporting it to the aneurysm 1, make the warped head of the microcatheter 6 enter the aneurysm 1; S02, send the coil 3 into the aneurysm 1 with the delivery guide wire 5, and when most of the coil 3 enters the aneurysm 1, adjust the spring Circle 3 shape to make the aneurysm embolization satisfactory, and then release it at the release point closest to the tip of the microcatheter; S03, such as figure 2 As shown, when releasing, electrify at the tail end of the microcatheter 6, and the electric current reaches the head end of the microcatheter 6 through the microwire on the wall of the microcatheter 6, and enters the nearest release point of the spring coil through the energized wire 7, and forms a circuit with the ...

Abstract

The invention discloses a multi-point electrolytic detachment system and method for detaching embolism materials. The system comprises a spring ring and a spring ring conveying system. The spring ring comprises a plurality of end-to-end small spring rings and detachment points for connecting the small spring rings. The spring ring conveying system comprises a conveying guide wire and a micro catheter. The conveying guide wire is arranged inside the micro catheter. The front end of the conveying guide wire is connected with the tail end of the spring ring through the last detachment point, an electrified wire is arranged at the front end of the micro catheter, a micro wire is arranged on the wall of the micro catheter, and the micro wire is connected with the electrified wire. Different detachment points are arranged on the spring ring, detachment is performed at nearby detachment points after arterial aneurysm embolism is satisfied, an existing multi-spring-ring implanting method is replaced, the operation time is shortened, and the operation cost of a patient is lowered.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-point electrolysis system and release method for releasing embolic materials, which is a multi-point electrolysis system for releasing embolic materials during the embolization process of intracranial aneurysm interventional treatment The principle of the system is to deliver the coiled embolization material into the aneurysm through the matching microcatheter, and set different release points on the coil according to the length. When the aneurysm is satisfied during the operation, it will be released at the nearest release point. Background technique [0002] A large number of autopsy or angiographic studies show that the incidence of intracranial aneurysms in the entire population is as high as 2%-4%. Once the intracranial aneurysm ruptures and bleeds, its mortality rate and disability rate are high. If two hemorrhages occur, the mortality rate is as high as 60%...
