Trocar(Protective Awl)

The protective cone puncture device is a highly safe solution for establishing the initial pneumoperitoneum and the primary access channel in laparoscopic surgery. Its core design lies in a retractable blunt protective cone that can pop out instantly after the puncture needle pierces the abdominal wall, separating the sharp needle tip from the internal tissues and organs, thereby significantly reducing the risk of iatrogenic injury. 

Core Features and Values:

· Active safety protection: The unique spring-driven protective cone mechanism covers the blade head immediately upon penetrating the abdominal wall, creating a "sharp first, blunt later" effect, effectively protecting deep tissues such as intestines and major blood vessels.

· Integrated design: Combines puncture, dilation, protection, and channel functions into one, simplifying operation steps and shortening the surgical time.

· Visual puncture experience: Some high-end models are equipped with transparent windows, allowing the surgeon to observe the tissue layers during the puncture process, enhancing the controllability and confidence of the puncture.

· Convenient pneumoperitoneum establishment: Usually comes with standard air inlet valves, enabling rapid connection to the pneumoperitoneum machine after successful puncture to establish and maintain pneumoperitoneum.

· Ergonomic design: The handle is designed to conform to hand mechanics, providing stable grip and controllable puncture force, enhancing the surgeon's operating feel.
