Summary
A new ultrasonic dissection handpiece enhances efficiency and safety in endoscopic surgery. This tool reduces hemorrhage risk and operating time during procedures on the esophagus, colon, and rectum.
Area of Science:
- Surgical Technology
- Minimally Invasive Surgery
- Gastrointestinal Surgery
Background:
- Ultrasonic dissection is a key technique in modern surgery.
- Existing tools may have limitations in complex anatomical areas.
- Need for improved dissection efficiency and safety in endoscopic procedures.
Purpose of the Study:
- To evaluate a novel handpiece designed for ultrasonic dissection.
- To assess its performance in minimal-access gastrointestinal surgery.
Main Methods:
- An experimental ultrasonic dissection prototype handpiece was developed.
- The device was used in 19 major endoscopic operations (esophagus, colon, rectum).
Main Results:
- Demonstrated increased dissection efficiency for challenging fibroareolar tissues.
- Enabled safe exposure of critical vascular pedicles, including in mesocolic fat.
- Significantly reduced the risk of major hemorrhage and decreased overall operating time.
Conclusions:
- The specifically designed ultrasonic dissection handpiece shows promise for endoscopic gastrointestinal surgery.
- It offers benefits in terms of efficiency, vascular safety, hemorrhage control, and time savings.
