Combined laparoscope gripper

The invention, which mainly relates to the field of medical instruments, discloses a combined laparoscope gripper comprising a detachable gripping head, a rod body and a detachable handle. The rod body and the detachable gripping head and the handle with different functions can be quickly assembled and disassembled, and only the gripping head and the handle with different functions need to be replaced when the gripper is replaced. During an operation, the detachable gripping head can be mounted after the rod body punctures into the abdominal cavity, so that the size, which can reaching3mm or below, of the operating hole is reduced as much as possible; and thus the size of the operating hole diameter only depends on the outer diameter of the rod body and does not depend on the outer diameter of the gripping head. When the combined laparoscope gripper is used for an operation, a rod body puncture hole does not need to be sewn, so that the postoperative pain is slight, and an operation scar can be ignored; and the operation habit of the laparoscopic surgery is the same as that of the traditional laparoscopic instrument, so that medical institutions and doctors who carry out the traditional laparoscopic surgery can use the laparoscopic surgery instrument to carry out surgery without special training, so that the surgical trauma of patients is further reduced.
