Blood vessel puncture site closer and operation method thereof

Abstract

The invention discloses a blood vessel puncture site closer and an operation method thereof. The blood vessel puncture site closer comprises a puncture site closing valve suite and a guide sheath. The guide sheath is inserted into skin and penetrates into a blood vessel in the skin, then the puncture site closing valve suite is inserted into the guide sheath, a push button is pressed down to enable a blood vessel closing valve to enter the blood vessel, then the guide sheath is made to exit, a traction line is pulled outwards, at the moment, a disc at the upper end of the blood vessel closing valve is located outside the wall of the blood vessel, a disc at the lower end of the blood vessel closing valve is tightly attached to the interior of the wall of the blood vessel, and finally the portion, exposed out of the skin, of the traction line is shorn off. The blood vessel puncture site closer can rapidly and effectively close a blood vessel puncture site and has the biodegradability. Vascular intervention postoperative complications can be reduced, postoperative recovery is promoted, and the blood vessel puncture site closer is the ideal blood vessel puncture site closing instrument, and has the wide market application prospect.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood vessel puncture port closer and an operating method thereof. Background technique [0002] Transvascular interventional diagnosis and treatment technology, as an emerging medical development, has been gradually promoted in China in recent years. The process is that under the guidance of medical imaging equipment, interventional medical devices are super-selectively delivered to the human body through naturally existing vascular channels. Organs and parts, such as: heart, liver, brain, kidney, digestive system, and reproductive system, are important technologies and methods for diagnosis and treatment, which have the advantages of no need for surgery, less trauma, and relatively low medical expenses. However, after vascular interventional diagnosis and treatment, closing the vascular puncture port often becomes a clinical problem. [0003] If the puncture port is poorly closed after va...

Problems solved by technology

There are also vascular suturers in foreign countries, but they need to be sutured, and their structure is more complicated, and there are many operation steps, such as the PercloseProglide vascular suturer of Abott Company; some such as Angio-seal of StJude Company may be due to the fixation problem and disintegration of the closure material in the blood vessel. Distal vessel occlusion and poor closure due to absorption
