Introduction of the Opti-trocar

Area of Science:

• Minimally Invasive Surgery
• Surgical Instrumentation
• Optical Engineering

Background:

• Conventional laparoscopy involves blind trocar insertion, posing risks of abdominal wall injury and incorrect placement.
• Current methods like minilaparotomy or open laparoscopy are sometimes required to ensure safe trocar placement.
• There is a need for improved visualization during trocar insertion in laparoscopic procedures.

Purpose of the Study:

• To develop and evaluate an optically clear trocar tip for enhanced visualization during laparoscopic surgery.
• To assess the feasibility of using video-aided continuous imaging for safe trocar insertion.
• To determine if the new trocar design can eliminate the need for additional open procedures.

Main Methods:

• An optically clear, image-receivable trocar tip was designed with optical engineering expertise.
• A prototype instrument underwent clinical testing in a feasibility study.
• The study involved 150 subjects undergoing laparoscopic procedures.

Main Results:

• The optically clear trocar tip allows for video-aided continuous visual imaging during insertion.
• Distinct layers of the abdominal wall were identified, ensuring proper intra-abdominal placement.
• The feasibility study indicated a significant advance in laparoscopic surgery performance.

Conclusions:

• The optically clear trocar tip represents a significant innovation for laparoscopic surgery.
• Wide-scale implementation can enhance surgical performance and patient safety.
• This technology facilitates precise trocar placement, potentially reducing complications and the need for open conversion.
