Problems solved by technology

[0005] The third limitation of GDC electrolysis coil design is that it is not suitable for the treatment of hemangiomas with wide mouth and neck, such as tumor cavity:neck ≤ 4:1, because the coil cannot be stably coiled and easily escapes from the hemangioma cavity, causing tumor-bearing arteries jam
[0006] The fourth limitation of the GDC electrolytic coil design is that it is not suitable for the treatment of huge hemangiomas

Embodiment Construction

[0019] The present invention will be further described now in conjunction with accompanying drawing

[0020] A detachable coil for the treatment of cerebrovascular tumors, comprising a coil 1 made of metal and a delivery guide wire 3 connected to it through a connector 2, the structure of which is: the connector 2 is an insulating polymer material adhesive, A polymer adhesive is placed in the area between the delivery wire and the coil. The length of the connection may be as short as 0.5mm, but generally no more than 5cm in length;

[0021] The coil 1 is covered with a coating 4; the coating is made of biodegradable polymer, or hydrogel liquid, or drugs capable of efficiently forming embolism. A variety of techniques can be used to coat polymers or hydrogels on metal surfaces, with or without drugs that enhance embolism in the coating. In the dip coating technique, the polymer is dissolved in a suitable solvent such as chloroform, toluene, methine chloride. The metal is the...

Abstract

The removable spring ring for treating angioma belongs to the field of angioma treating technology and medical equipment technology. The removable spring ring for treating angioma includes one spring ring with one coating of biodegradable polymer, hydro gel or medicine for efficient embolism, and one conveying duct connected to the spring ring via insulating polymer adhesive. The polymer coating in the spring ring can speed the formation of coagulated tissue inside the angioma to embolize and has controllable degrading speed; the hydro gel can expand in blood or moisture condition for dealing with giant aneurysm; and the medicine for efficient embolism can raise the treatment effect.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, specifically a technology related to the treatment of hemangioma. Background technique [0002] The electrolysis coil medical device is used to treat cerebral hemangioma, which is a thin-walled hemangioma that grows on the cerebral artery and communicates with it. Once the hemangioma ruptures, the patient's life is in danger. When treating cerebral hemangioma with an electrolysis coil medical device, the doctor uses a special catheter to send a special platinum coil into the hemangioma, and then passes a 1mA to 2mA direct current through the catheter, causing the platinum coil to electrolyze from the catheter and remain in the hemangioma. In a hemangioma. When the volume occupied by one or more platinum coils reaches a certain proportion of the entire hemangioma volume, the blood flow rate in the hemangioma gradually decreases, and finally a solid body is form...
