The invention discloses a vascular clamp used in a vascular surgery department. The vascular clamp comprises a clamp module, an adsorption module and an adjusting module, wherein the clamp module comprises a pressing button, a pressure cylinder, a pressure spring, a pressure conveying tube, an execution telescopic cylinder and an execution telescopic rod; the pressure cylinder is connected with the outer surface of the pressing button in a sliding manner; the pressure spring is arranged between the bottom of the pressing button and the bottom of the inner wall of the pressure cylinder; the execution telescopic cylinder communicates with a part below the pressure cylinder through the pressure conveying tube; and the execution telescopic rod is moveably connected with the inner wall of the execution telescopic cylinder. Due to adoption of the adjusting module, when one vascular clamp block is adjusted, the other vascular clamp block can be driven to move together, then the time for adjustment can be shortened, and furthermore, the use efficiency of the device can be improved; due to adoption of the adsorption module, a blood vessel can be well adhered to surfaces of a blood vessel clamp cylinder and blood vessel clamp blocks, so that the blood vessel can be prevented from dissociation by accident in the operation process of a doctor, and furthermore, the use security degree of the device can be increased.
