Separable portal vein blocker

The utility model relates to the technical field of medical instruments, in particular to a separable portal vein blocker which is used in the common open hepatectomy. The separable portal vein blocker comprises a pair of portal vein blocking forceps and a blocking forceps operator, wherein the pair of portal vein blocking forceps comprises a pair of forceps holder limbs (1), a limb connecting shaft (2) and a spring (3); the pair of forceps holder limbs (1) is crosswise connected; the opposite surfaces of front arms (1.1) of the pair of forceps holder limbs are provided with complementary transverse bar-shaped teeth; the blocking forceps operator comprise a pair of forceps arms (4) and a forceps arm connecting shaft (5), wherein the pair of forceps arms (4) is crosswise connected; the opposite surfaces of the head of a clamp forceps (4.1) are provided with lockholes (4.3) matched with lock catches (1.3) of the tail parts of the pair of portal vein blocking forceps for being connected with the pair of portal vein blocking forceps; and the tail parts of forceps handles (4.2) are provided with rings (4.4). In the separable portal vein blocker, because the pair of portal vein blocking forceps and the blocking forceps operator are separable and the rear arms of the pair of portal vein blocking forceps are short, few parts under the surgery are blocked, which is favorable for liver tumor or hepatic hemangioma exsection.
