The invention discloses a laparoscopic vascular disconnector. The device includes a left tissue clamping device, a right tissue clamping device, a tissue clamp, central scissors of the clamping devices, a connecting rod, a fixed handle, a movable handle, a pincer barrel body, movable links, fixed links and tissue clamp fixing grooves. When laparoscopic vascular cutting operation techniques are conducted with the laparoscopic vascular disconnector, the two sides of a blood vessel can be quickly clamped with the tissue clamp, after it is ensured that the blood vessel is clamped definitely and completely, the device is pushed forward, the central scissors of the clamping devices can cut the blood vessel off quickly, the operation time is saved, and the tissue clamp is firm and cannot slip. Meanwhile, according to the cut end of the tissue, it is judged whether the tissue is the blood vessel, a bile duct or other tissue, it is prevented that when an electric knife, an ultrasonic knife or an energy platform is used for cutting off the tissue, which kind of the tissue is cannot be determined, and the problem of rebleeding after thick blood vessels are cut is solved; through clinical practice, the device is convenient, quick and flexible for the operation techniques, and the operation safety is effectively improved.
