    Area of Science:

    • Medical technology
    • Surgical innovation
    • Minimally invasive surgery

    Background:

    • Postoperative complications, particularly anastomotic leakage, are common in challenging laparoscopic procedures.
    • Uneven suture spacing during surgery contributes significantly to anastomotic leakage.
    • Current methods rely on surgeon intuition, making uniform suture spacing difficult.

    Purpose of the Study:

    • To develop a model for visualizing suture needle tips within organs during surgery.
    • To improve surgical accuracy and reduce the incidence of anastomotic leakage.
    • To provide real-time feedback on needle placement.

    Main Methods:

    • Construction of a novel model to visualize the suture needle tip.
    • Testing image inference capabilities of the developed model.
    • Evaluation of real-time performance and estimation accuracy.

    Main Results:

    • The model achieved a real-time processing speed of 33.4 frames per second.
    • The average estimated misalignment of the needle tip was 1.03 mm.
    • This misalignment is less than 1.8 mm, representing 10% of the total needle length.

    Conclusions:

    • The proposed model effectively estimates the position of hidden suture needle tips.
    • This visualization technology has the potential to significantly improve surgical accuracy.
    • The findings suggest a reduction in anastomotic leakage and improved patient outcomes.
