The present invention relates to the field of medical devices, in particular to a rubber stent supporting blood vessels, comprising a first elastic member and a second elastic member. The first elastic member includes a first elastic ring, a second elastic ring, a first elastic strip, a first elastic The ring rotates along the first direction; the middle part of the first elastic bar is sunken inward, and the left and right ends are respectively connected to the first elastic ring and the second elastic ring, and the left end is located at the front side of the right end along the first direction; the second elastic member includes the first Three elastic rings, the fourth elastic ring, and the second elastic ring, the diameter of the third elastic ring is smaller than the diameter of the fourth elastic ring and the diameter of the second elastic ring; Three elastic rings and a fourth elastic ring, and the left end is located at the rear side of the right end along the first direction; the third elastic ring is connected to the second elastic ring and is separated under the action of external force; the third elastic ring is connected to the second elastic ring The rear diameter is increased and the diameter of the fourth elastic ring is reduced to facilitate access to blood vessels.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a blood vessel supporting rubber stent. Background technique [0002] The disconnected blood vessels need to be sutured, but because the walls of the blood vessels are thin, the front and rear walls are easy to stick together, making suturing difficult, and the stitch length of the suture is difficult to control under non-inflated conditions, and postoperative bleeding often occurs. In the prior art, the artificial blood vessel anastomosis method is adopted, and a supporting member with a suitable diameter is selected to open the fracture of the blood vessel for suturing. The small diameter of the supporting member is easy to enter the blood vessel, but the blood vessel will not be fully opened, and the large diameter of the supporting member can be fully opened. Blood vessels, but difficult to enter the blood vessels, therefore, need a kind of blood vessel support stent that can n...
