Problems solved by technology

[0007] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a fully recyclable braided stent to solve the following problems in the prior art: First, the braided stent cannot be recycled after releasing more than 80% , resulting in inaccurate positioning and poor apposition, but cannot be readjusted; second, because the braided stent is cumbersome to operate during the operation, it is prone to early release

Embodiment 1

[0086] Such as Figure 4-7 As shown, the proximal end of the knitted component 16 is uniformly distributed along the circumference with the same number of first looped knitting rings 21 and the second looped knitting rings 22, and the distal end of the knitted component 16 is evenly distributed along the circumference with the same number of the third looped knitting rings 80 and the fourth looped knitting rings. Ring 82. The distance from the first revolving braiding ring 21 to the proximal connecting rod 11 is smaller than the distance from the second revolving braiding ring 22 to the proximal connecting rod 11 . Each of the second intersection points 69 has a second insertion hole 70 through which the first looped knitting rings 21 pass through to play the role of connecting the cutting component 14 and the knitting component 16 .

Embodiment 2

[0088] Such as Figure 8 As shown, it is another knitting method of the present application. The cutting part 14 has a first penetration hole at the first intersection point 65, and a second penetration hole 70 at the second intersection point 69, through which the first looping knitting ring 21 passes. The first through hole and the second looped knitting ring 22 pass through the second through hole 70 , so as to achieve the purpose of connecting the cutting component 14 and the knitting component 16 .

Embodiment 3

[0090] Such as Figure 9 , in another embodiment, the cutting component 14 and the knitting component 16 are connected through the first looped knitting ring 21 passing through the second insertion hole 70 , and a two-strand braided structure is formed at the connection. The braided structure here is used as a non-slip structure to place the braided wire to slide in the insertion hole, and it can also be connected by a fixed connection such as welding.

[0091] Compared with the first connection method, the connection between the looped braided ring and the insertion hole in this connection structure is not easy to slide and is more stable.

[0092] Such as Figure 12 As shown, the braided component 16 in this application is made of a braided wire 15 spirally wound and woven along the braiding tool 75, and the braiding tool 75 includes a braiding mandrel 29 and several groups of winding columns that are staggered along the axis and distributed on the braiding mandrel 29 30, ...

Abstract

The invention discloses a knitting support capable of being completely recycled. The knitting support comprises a support body of a tubular structure as a body for supporting a blood vessel, a pushing recycling device and a cutting component. The body comprises a cutting component and a knitting component, the cutting component is close to the near end of the support, and the knitting component is close to the far end of the support; the push recycling device is detachably connected with the support body for pushing and recycling the support body inside a guide pipe, the near end of the cutting component is connected with the pushing recycling device, and the far end of the cutting component is connected with the knitting component, wherein a crossing hole is formed in the cutting component for crossing and knitting knitted wires of the knitting component. The knitting support capable of being completely recycled has the advantages that compared with the prior art, after the knitting support is completely released, if the problems that positioning of the support is not accurate and wall adhesion is poor appear, the support can be recycled into a micro guide pipe and positioned and released again, and therefore operation safety is ensured.

Description

technical field [0001] The invention relates to a completely recoverable braided stent, which is an implant device for treating intracranial blood vessels, and belongs to the technical field of stent-assisted embolization of intracranial vascular aneurysms. Background technique [0002] Aneurysm is a very common vascular disease, which is caused by the swelling of the arterial wall due to local lesions, forming a permanent limited expansion. Aneurysms can occur anywhere in the arterial system, but the most common place where aneurysms occur is in the cerebral arteries. Intracranial aneurysms are a cerebrovascular disease with high morbidity and mortality. main reason. Surgical clamping and vascular intervention are the two main methods for the treatment of intracranial aneurysms. Interventional treatment of intracranial aneurysms has become the first choice for many hospitals due to its characteristics of small trauma, high safety, and good postoperative healing. At presen...
