Abstract
The embodiment of the invention relates to a spring ring conveying releasing system. The spring ring conveying releasing system comprises a spring ring, a developing mark and a conveying releasing device. The developing mark is fixedly connected with the spring ring; the conveying release device comprises an elastic balloon and a conveying pipe; the far end of the elastic balloon is accommodated in the developing mark, and the near end of the elastic balloon is bonded with the conveying pipe; the conveying pipe is communicated with the interior of the elastic balloon to form a cavity for accommodating a gas; and an inflation sealing component is arranged at the near end of the conveying pipe, and a fracture structure is arranged at the position, away from the inflation sealing component bya certain distance, of one side of the near end. External inflation equipment inflates the cavity through the inflation sealing component; under the action of the elastic balloon and the conveying pipe, the spring ring and the developing mark are conveyed to a target position through the interior of a micro-catheter; the fracture structure fractures under the action of external force, the gas inthe cavity leaks, the elastic balloon contracts and is disengaged from the developing mark, so that the developing mark is separated from the elastic balloon, and the spring ring and the developing mark are disengaged from the conveying release device.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a spring coil delivery and release system. Background technique [0002] At present, clinically, for patients with aneurysms, especially cerebral aneurysms, arterial interventional coils are usually used for packing treatment. However, the coil implantation for the treatment of aneurysms must achieve controllable release of the implanted part. There are many ways to release the spring coil. Among them, the mainstream method of mechanical release is the ferrule type, that is, adding a movable connecting rod. The end of the movable connecting rod is spherical. The first end of the movable connecting rod is connected with the spring coil. The movable connecting rod is assembled and placed into the delivery catheter, and the coil is released by withdrawing the release wire. However, during release, the release point is easily affected by mechanical force, resulting in deviat...
