Laparoscope 30-degree steering prism system

The utility model discloses a laparoscope 30-degree turning prism system, which comprises a first objective lens, a transmission prism, a reflecting prism and an optical path compensating mirror, the first objective lens is a plano-concave lens, the transmission prism is arranged on the side surface of the first objective lens, a compensating prism is arranged on the side surface of the reflecting prism, and the compensating prism is used for normalizing a prism structure. The optical path compensating mirror is arranged on the side face of the compensating prism and is a plano-convex lens. According to the 30-degree viewing angle prism system of the laparoscope provided by the utility model, the eccentricity phenomenon in the gluing process of the 30-degree viewing angle prism system and the first lens is effectively controlled, so that the installation and adjustment difficulty and the use cost are effectively reduced, the imaging quality of the laparoscope is further improved, the gap between the laparosco
