Embodiment 1

[0029] The present invention provides a suturing method for closing the opening of a blood vessel, which comprises the following steps:

[0030] 1. Insert a guide wire 2 into the opening of the blood vessel by the Seldinger puncture method.

[0031] 2. Send the upper support balloon to the opening of the blood vessel along the guide wire 2. After the upper support balloon 41 is placed in the blood vessel cavity, use the catheter 44 connected with the upper support balloon 41 to fill the upper support balloon 41 as required. Gas is injected to make the upper support balloon 41 inflated, and then the inflated upper support balloon 41 can abut against the inner wall of the opening of the blood vessel through the lifting catheter 44 .

[0032]3. Translate the push rod 42 provided outside the catheter 44 along the catheter 44 of the upper support balloon 41 to the opening of the blood vessel. The axial lower end of the push rod 42 can be attached to the outer wall of the blood vess...

Embodiment 2

[0037] The present application also provides a suturing device for closing a blood vessel opening, which may include a puncture needle 1 , a guide wire 2 , a guide wire sheath 3 , an adjustment assembly 4 and a suturing unit 5 .

[0038] according to figure 2 In a specific embodiment shown, a puncture needle 1 with a needle core is inserted into the lumen of a blood vessel through an opening of a blood vessel along a set path. The guide wire 2 is inserted into the lumen of the blood vessel along the axial needle cannula of the puncture needle 1 from which the insertion operation is completed and the needle core is removed. After the guide wire 2 is partially inserted into the blood vessel lumen, the puncture needle 1 is pulled out, and the guide wire sheath 3 is inserted into the blood vessel lumen along the guide wire 2 . The upper support balloon 41 of the adjustment assembly 4 is disposed on the guide wire sheath 3 , and the upper support balloon 41 can follow the guide w...

Abstract

The invention relates to a suturing device for closing a blood vessel opening, at least comprising a puncture needle capable of introducing a guide wire into a blood vessel cavity, the guide wire being capable of guiding a guide wire sheath tube provided with an upper support balloon into the blood vessel cavity, the guide wire sheath tube being inserted into the blood vessel cavity in the event of expansion of the upper support balloon. The clamping unit can clamp a blood vessel wall in a blood vessel opening area in a mode of being matched with the push rod, so that the suture unit can perform suture needle puncture operation on the blood vessel wall at the edge of the blood vessel opening; the upper supporting balloon can be placed into a blood vessel cavity from a blood vessel opening so as to cover the blood vessel opening and the peripheral part of the opening from the inner surface of the blood vessel wall under the condition that the upper supporting balloon expands; the push rod can cover the blood vessel opening and the peripheral part of the opening from the outer surface of the blood vessel wall, so that the upper supporting balloon and the push rod can clamp the blood vessel wall in the blood vessel opening area under the relative acting force. In addition, the invention also relates to a suturing method for closing a blood vessel opening.

Description

technical field [0001] The present invention relates to the technical field of transcatheter treatment, and in particular, to a suturing device and method for sealing an opening of a blood vessel. Background technique [0002] Vascular closures are medical devices used for hemostasis at the puncture point after percutaneous vascular puncture. They can shorten the hemostasis time, immobilization time and hospitalization time after interventional therapy, reduce patient trauma, improve patient comfort, and reduce the work of medical staff. burden. [0003] At present, the common vascular closure devices on the market can be roughly divided into active vascular closure devices, compression-assisted closure devices and surface hemostatic stickers. Active vascular closure devices use various methods to directly close the puncture point. According to their principles, they can be divided into 3 types: ①Close to the outer surface of the puncture point to release collagen and other...
