A technique for real-time digital measurements in laparoscopic surgery

Area of Science:

• Surgical Technology
• Medical Imaging
• Minimally Invasive Surgery

Background:

• Current methods for measuring intracorporeal targets in laparoscopic surgery are often cumbersome and lack precision.
• There is a need for improved techniques to enhance accuracy in laparoscopic measurements.

Purpose of the Study:

• To introduce and evaluate a novel structured light technique for measuring intracorporeal targets during laparoscopic surgery.
• To compare the accuracy and speed of the structured light technique against existing laparoscopic measurement methods.

Main Methods:

• A structured light technique was employed to measure the dimensions of defects and an object within a laparoscopic training box.
• Measurements were compared to traditional methods: using a plastic ruler and approximating with a laparoscopic instrument end.
• The time required for each measurement technique was recorded.

Main Results:

• Structured light measurements demonstrated the highest accuracy, closely followed by the plastic ruler, and then the instrument-end approximation.
• The structured light technique was the fastest measurement method, outperforming the instrument-end and plastic ruler methods.

Conclusions:

• The novel structured light technique provides superior accuracy for laparoscopic measurement of intracorporeal targets compared to current standard techniques.
• This digital approach enhances precision and efficiency in laparoscopic surgery.
