Abstract

The invention discloses a bridging stent based on temporary recanalization of blood circulation, comprising two unit staplers sleeved on both ends of an infusion tube respectively, the unit stapler includes a blood vessel sleeve connector, the blood vessel sleeve is placed on the free end of the blood vessel sleeve connector, There is a channel connecting the blood vessel and the infusion tube; the blood vessel cuff joint is sheathed with a blood vessel clamping fixture, and the blood vessel clamping fixture includes a sub-clamp arm and a mother-clamp arm, and the sub-clamp arm and the mother-clamp arm are buckled on the peripheral wall of the blood vessel . At the same time, the processing method of the patented product is also disclosed. The main body parts are molded with elastic materials, then deburred and smoothed; they are assembled together with the infusion tube in sequence. The advantages of the invention are that it can quickly and accurately supply the blood vessels of the amputated limbs, solve the problem of losing blood supply to the amputated limbs after the limbs are amputated, restore the blood circulation of the distal amputated limbs in a timely manner, reduce the warm ischemia time, and avoid the isolation of the limbs. Necrosis of severed limbs, and has the characteristics of reasonable structural layout, high precision of coordination of various mechanisms, and safety and efficiency.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to temporary vascular bypass used in the treatment of extremity blood vessels, in particular to a bridging stent used based on the temporary recanalization of blood circulation and a processing method thereof. Background technique [0002] At present, in modern industrial machinery accidents, serious car accidents, earthquakes, field first aid, etc., it is common to encounter serious injuries to the limbs and large limbs, damage and interruption of blood supply to the distal limbs caused by the large arteriovenous system, and even limb disconnection. In the treatment of such patients, it is required to repair the main arteries and veins as soon as possible to restore the blood circulation of the distal limbs, reduce the warm ischemia time, and avoid the necrosis of the large limbs. However, in the current trauma emergency process at home and abroad, because there is no simple and reli...
