Disposable Suction Irrigation Instrument: A Four-in-One Instrument for Endoscopic Surgery

The traditional electrocautery hook is a commonly used instrument in surgical procedures. However, it often produces a large amount of surgical smoke and some bleeding during use, requiring coordination with a separate suction–irrigation device. The frequent switching and coordination between instruments can reduce surgical efficiency. The newly developed suction-irrigation electrosurgical cutter, with its integrated functions and scenario-oriented design, has become a powerful alternative to the conventional electrocautery hook.

Developed independently by ShouLiang-med, the Disposable Suction Irrigation Instrument integrates electrocoagulation, electrocision, irrigation, and suction into one device. It allows precise coagulation of small vessels to seal and control bleeding, while its diverse electrode shapes enable delicate tissue dissection, traction, and anatomical separation. The built-in channel system can deliver saline or other irrigation fluids to the surgical field, keeping tissues moist, cooling them down, and improving visibility. It can also suction fluids, smoke, and tissue debris from the field to maintain a clear view. By using this single instrument, the need for frequent instrument changes is greatly reduced, achieving an operational loop of “irrigate as you point, coagulate as you clean, and suction as you coagulate.” This provides surgeons with a more convenient and effective tool for many typical clinical scenarios.

For example, in laparoscopic cholecystectomy (LC), dissection of Calot’s triangle is a key and challenging step. When separating the gallbladder from the liver, surgeons need to delicately dissect adhesions and fatty tissue around the cystic duct and cystic artery using an electrocautery hook. The gallbladder bed often presents diffuse oozing. At this stage, the EA31303 hook-type instrument enables precise dissection and cutting, clear exposure of ductal structures, and effective coagulation of small vessels to control bleeding while maintaining a clean dissection plane. With its integrated suction and irrigation functions, the surgeon can instantly activate irrigation or suction via hand control without switching instruments. This quickly restores a clear view and enhances the safety of bile duct identification.

Therefore, the suction-irrigation electrosurgical cutter is especially suitable for minimally invasive surgeries involving complex anatomy, limited operating space, frequent bleeding, and high demands for visual clarity. The ShouLiang-med Disposable Suction Irrigation Instrument series, through its ingenious functional integration, effectively addresses key pain points in minimally invasive surgery. It serves as a powerful tool to improve both surgical efficiency and safety, providing a more convenient and comprehensive solution for these demanding surgical environments.
