AI Technical Summary
Existing surgical electrodes used in minimally invasive intraperitoneal surgery are bulky due to the parallel extraction and injection channels, which cannot meet the requirements of multifunctionality and miniaturization in minimally invasive surgery.
Design a multifunctional energy confinement scalpel for laparoscopy that integrates the functions of fluid extraction, saline injection, and smoking into one unit. This is achieved through a single fluid channel and connected to external devices using a multi-channel connector. Combined with a retractable tube and a multi-channel valve structure, it enables the coordinated operation of multiple functions.
Effective control of surgical electrode volume enhances operational flexibility and precision, reduces the risk of cross-contamination, improves surgical efficiency and quality, and lowers manufacturing costs.
