Problems solved by technology

[0002] Conventional stents are braided with one wire, and the number of ends is fixed according to the number of braided ends, which cannot be changed, and the braided wire is made of metal, which is relatively hard and easy to stimulate the tube wall to cause hyperplasia
Moreover, most of the stents on the market are artificially woven, which is difficult and limited in production capacity, and the existing woven stents are difficult to handle at the head end

Embodiment 1

[0024] Such as figure 1 , a lumen stent with end protection disclosed in Embodiment 1, comprising a stent body 1, a connecting tube 2, a spiked part 3, a sleeve part 4 and a connecting part 5, and a circle of spiked parts is arranged at both ends of the stent body 1 3. The sleeve part 4 of the connecting pipe 2 covers the spiked part 3. In this embodiment, one connecting part 5 corresponds to two sleeve parts 4, and the connecting pipe 2 has a U-shaped structure as a whole. The connection part and the casing part are of an integral structure. The sleeve part adopts heat shrinkable tube. The sleeve part 4 can cover a spiked part 3, or the sleeve part can be made larger, and one sleeve part is sleeved with two or three spiked parts.

[0025] The invention also discloses a preparation method of a lumen support with end protection, comprising the following steps:

[0026] Step 1: Sleeve the sleeve part of the connecting pipe on more than one sharp part at the end of the bracket...

Embodiment 2

[0035] In this example, if figure 2 , the connecting pipe includes a connecting part 5 and three sleeve parts 2, and the three sleeve parts are respectively located at both ends and the middle of the connecting part. .

Embodiment 3

[0037] In this example, if image 3 , the connecting part 5 is a ring structure, and a group of vertical casing parts 2 are arranged on the ring structure.

Abstract

The invention provides a tract stent with end protection, which comprises a stent body. Two ends of the stent body are provided with connecting pipes. The connecting pipes comprise a connecting part and two or more sleeve parts. One end of the sleeve part is sheathed on the stent body and the other end is connected to the connecting part. The stent body includes spike portions at both ends, and the spike portion is sleeved with the sleeve part. The tract stent with end protection is simple in structure, easy to implement, can reduce the irritation to the wall, and reduce the chance of proliferation and perforation. The stent is easy to be recovered, which changes the difficult recovery problem of the traditional stent.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a lumen support with end protection. Background technique [0002] Conventional stents are braided with one wire, and the number of ends is fixed according to the number of braided ends, which cannot be changed. The braided wire is made of metal, which is relatively hard and can easily stimulate the tube wall to cause hyperplasia. Moreover, most of the stents on the market are artificially woven, which is difficult and the production capacity is limited, and the head end of the existing woven stents is difficult to handle. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a lumen bracket with end protection for the deficiencies of the prior art. [0004] In order to solve the above technical problems, the present invention provides a lumen support with end protection, which includes a support ...
