The invention discloses a pair of sheathing type blood vessel occlusion clamps for dealing with hemorrhage of a blood vessel during thoracoscope pulmonary surgery. The pair of sheathing type blood vessel occlusion clamps consists of outer sheaths and a double-joint opening and closing device, wherein the double-joint opening and closing device comprises two arm bodies which are mutually connected in parallel, each arm body comprises three parts of a front arm, a middle arm and a rear arm, two pairs of homodromous curving cusps extending forwards respectively are arranged at front parts of the two front arms, so that when the pair of sheathing type blood vessel occlusion clamps is closed, the cusps at the inner side and the outer side are respectively mutually matched, meanwhile gaps are respectively formed between the cusps at the inner side and the outer side as well as between the cusps at the inner sides and the rear end parts of the two front arms; the two outer sheaths are arranged, are made of medical grade rubber, and the sizes and shapes of the outer sheaths are matched with those of the two front arms. The pair of sheathing type blood vessel occlusion clamps disclosed by the invention is convenient to control the hemorrhage, quick and convenient, accurate, and capable of avoiding exacerbation of the injury around a rupture of a vessel wall, and reducing the occurrences of thrombus, stenosis and secondary hemorrhage.
