Summary
Ultrasonically activated coagulating shears simplify liver surgery by welding and dividing blood vessels during hepatic parenchymal transection. This innovative technique shows potential to improve surgical procedures.
Area of Science:
- Surgical Technology
- Hepatobiliary Surgery
- Medical Devices
Background:
- Coagulating shears (CS) utilize a tissue-welding technique to seal and divide medium-sized blood vessels.
- Hepatic parenchymal transection is a critical step in liver surgery, often involving complex vessel management.
Purpose of the Study:
- To present and evaluate the application of ultrasonically activated coagulating shears in hepatic parenchymal transection.
- To assess the potential of CS to simplify and enhance liver surgery procedures.
Main Methods:
- The forceps fracture method was used to expose intrahepatic vessels.
- Ultrasonically activated coagulating shears were employed to coagulate and divide exposed vessels.
- Larger vessels were ligated on the preserving side prior to CS application.
Main Results:
- Coagulating shears effectively coagulated and divided intrahepatic vessels during the procedure.
- The method demonstrated a potential for simplifying the transection process.
Conclusions:
- Ultrasonically activated coagulating shears offer a promising approach for hepatic parenchymal transection.
- Further refinement of the CS tip may enhance its utility in liver surgery.
