Area of Science:

Minimally Invasive Surgery
Surgical Technology
Medical Device Evaluation

Background:

Standardized testing procedures are lacking for Natural Orifice Translumenal Endoscopic Surgery (NOTES) instruments.
This deficiency hinders the evaluation of surgical skills and instrument quality, impeding NOTES advancement.
Endoscopic surgeons recognize this as a significant obstacle to progress in the field.

Purpose of the Study:

To develop standardized testing procedures for Natural Orifice Translumenal Endoscopic Surgery (NOTES) instruments.
To create novel tasks specifically designed for evaluating endoscopic surgical forceps.
To establish a foundation for assessing both instrument performance and individual surgeon competency in NOTES.

Main Methods:

Adapted and modified existing laparoscopic surgical tasks.

Designed new tasks to specifically evaluate endoscopic surgical forceps.

Developed six distinct tasks: Fuzzy Ball, Cup Drop, Ring Around, Material Pull, Simulated Biopsy, and Force Gauge tasks.

Main Results:

Six novel tasks were successfully developed and implemented.
These tasks were utilized to evaluate a new forceps instrument from Pennsylvania State University.
The developed tasks demonstrated applicability in assessing endoscopic instrument performance.

Conclusions:

The study addresses the critical need for standardized testing procedures in Natural Orifice Translumenal Endoscopic Surgery (NOTES).
The developed tasks provide a foundational framework for evaluating new NOTES forceps instruments.
These tasks can also be used to assess the performance of individual surgeons using endoscopic forceps.
