Laparoscopic-assisted binding ligator for treating prostate back side venous plexuses and application

The invention provides a laparoscopic-assisted binding ligator for treating prostate back side venous plexuses. The binding ligator comprises a rotating shaft, a head, a neck of a bent extension arm,an abdomen of an arc-shaped supporting arm and a tail, the head is provided with an arc-shaped cylindrical gripper and a tubular structure, and the tail is a connecting rod and connected with a ring.The binding ligator can realize whole suture detachment of the prostate back side mesh deep venous plexuses and surface fascia thereof, a surgery is nearly performed under direct vision, and anatomical layers and structures are more clearly seen in a laparoscopic-assisted manner. Accurate operation is facilitated, wounds are decreased, the surgery can be performed without CO2 pneumoperitoneum, andsurgical indications are widened. The binding ligator can be applied to classic open surgeries and can also be applied to the currently most widespread minimally invasive laparoscopic surgeries. Theclinical application of the
