A newly designed single dissector useful for laparoscopic cholecystectomy

Area of Science:

• Minimally Invasive Surgery
• Surgical Instrumentation

Background:

• Laparoscopic cholecystectomy often requires multiple instrument exchanges.
• Current instruments can limit efficiency during complex dissection steps.

Purpose of the Study:

• To introduce a modified dissector for single-handed laparoscopic cholecystectomy.
• To evaluate the feasibility of performing the procedure with a single, multi-functional instrument.

Main Methods:

• Development of a novel dissector integrating grasping, sharp/blunt dissection, and tissue division.
• Application of the dissector in laparoscopic cholecystectomy procedures.
• Assessment of procedural time and safety outcomes.

Main Results:

• The modified dissector successfully performed all three functions (grasping, dissection, division) with one hand.
• Laparoscopic cholecystectomy was completed rapidly and safely.
• Eliminated the need for instrument changes through the trocar during the procedure.

Conclusions:

• The developed dissector facilitates efficient and safe one-handed laparoscopic cholecystectomy.
• This innovation simplifies surgical workflow and reduces operative time.
• Potential to improve surgeon ergonomics and patient outcomes in laparoscopic procedures.
