As a core functional component directly acting on the intra-abdominal surgical site during laparoscopic procedures, it is primarily positioned as a minimally invasive surgical field manipulation aid. Its key functions include tissue dissection, surgical site retraction, and directional guidance. Featuring a smooth, toothless, and finely curved structure, it gently exposes the target surgical area within the confined laparoscopic field of view, avoiding unnecessary tissue damage. Designed for non-grasping and low-friction applications, it aligns with the “minimally invasive, precise” operational requirements of laparoscopic surgery. The large central connection hole is not designed for manual holding but rather for high-precision integration with subsequent transmission modules, serving as the critical functional endpoint of the laparoscopic instrument.

This component serves as the primary transmission and connection hub within the endoscopic instrument system, facilitating the interface between the end-effector tip and the rear-end power/fluid modules. Its CNC-machined cubic structure, equipped with precision-drilled holes, ensures stable connection to drive rods and push-pull transmission mechanisms. The externally threaded nozzle is compatible with fluid channels for irrigation, suction, or other fluid/gas delivery needs, guaranteeing consistent media transfer during surgical procedures. Transverse threaded holes enable secure locking and positioning of components, ensuring uninterrupted reliability of transmission or fluid pathways throughout surgery. It acts as a vital intermediary for power and fluid signal transmission in endoscopic instruments.

This component functions as the core assembly and positioning interface between various endoscopic instrument modules and the endoscope body (or surgical equipment). Its tapered structure enables high-precision coaxial alignment with upstream components, ensuring operational accuracy following multi-module integration. The flange design allows for quick and secure attachment to the endoscope or equipment module while providing robust sealing performance to prevent intraoperative leakage of bodily fluids or gases. Balancing assembly efficiency and connection stability, it plays a crucial role in reducing surgical setup time and maintaining the overall assembly precision of the instrument, serving as a key transitional component in the endoscopic system.
