Problems solved by technology

Traditional vascular stents are regular in shape and have a uniform columnar mesh structure. This kind of stent is only suitable for the treatment of single vessel lesions. When it is applied to lesions at the opening of branch vessels, due to the lack of accurate positioning structure, Inaccurate positioning of the dilatation balloon during delivery to the lesion can result in excessive stent retention in the main vessel or excessive penetration of the stent into branch vessels, both of which can lead to dilation of the lesion Incomplete, which affects the treatment effect, and in severe cases, it will aggravate the patient's blood vessel blockage or thrombosis, which will bring great pain to the patient

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as Figure 1~4 As shown, the present invention is composed of a positioning part 101 and an expansion part 102; the expansion part 102 is a regular-shaped columnar mesh, which is used to expand and support the lesion at the opening of the branch blood vessel; the positioning part 101 is ring-shaped, and the expansion part The end of 102 is integrally processed and formed;

[0018] The positioning part 101 is arranged at the junction of the main blood vessel and the branch blood vessel, and acts to limit the positioning of the stent through the cooperation with the positioning guide wire 3; extension within the supervisor;

[0019] The guide wire 2 is inserted inside the expansion part 102, which is used to enter the branch blood vessel under the traction of the guide wire 2, and accurately locate at the opening of the br...

Abstract

The invention discloses a stent for lesions of a branch blood vessel opening. The stent is composed of a positioning part and an expansion part, wherein the expansion part is of a columnar net shape with a regular shape; the positioning part is an annular; the tail end of the expansion part is integrally machined and formed; the positioning part is arranged at a connecting part of a main blood vessel and a branch blood vessel and the stent is positioned through common effect of the positioning part and a positioning guide wire; the positioning guide wire stretches from the main blood vessel, penetrates into the positioning part and then extends into a main pipe of the branch blood vessel; a lead guide wire is inserted into the expansion part; the lead guide wire enters the branch blood vessel under the dragging effect of the lead guide wire; the lesions of the branch blood vessel opening are accurately positioned under the common effect of the positioning part and the positioning guide wire. When the stent provided by the invention is applied to interventional therapy of the lesions of the branch blood vessel opening, the stent has the advantages of accuracy in positioning and good blood vessel dredging effect; a current situation that the positioning of a traditional stent is not accurately positioned so that the lesions of the branch blood vessel opening are not completely expanded can be completely solved, and a development process of modern medical treatment is facilitated.

Description

technical field [0001] The invention relates to a stent, in particular to a stent used for lesions at the opening of branch blood vessels, and belongs to the technical field of medical auxiliary equipment. Background technique [0002] Vascular stent refers to a medical device that, on the basis of luminal balloon dilation and shaping, inserts an internal stent in the lesion to support the stenotic and occluded vessel, reduce the elastic retraction and reshaping of the vessel, and maintain the smooth blood flow in the lumen. Traditional vascular stents are all regular in shape and have a uniform columnar mesh structure. This kind of stent is only suitable for the treatment of single vessel lesions. When it is applied to lesions at the opening of branch vessels, due to the lack of accurate positioning structure, Inaccurate positioning of the dilatation balloon during delivery to the lesion can result in excessive stent retention in the main vessel or excessive penetration of ...
