Area of Science:

  • Surgical Innovation
  • Minimally Invasive Surgery

Background:

  • Laparoscopic surgery requires precise dissection and visualization of anatomical structures.
  • Existing tools may pose risks of thermal injury, tearing, or hemorrhage.

Purpose of the Study:

  • To introduce and describe the DisePad, a novel endoscopic dissector for laparoscopic procedures.
  • To evaluate the device's efficacy in improving dissection, separation, and cleaning of anatomical structures.

Main Methods:

  • The DisePad endoscopic dissector was designed and patented.
  • Its unique tip comprises a cotton-polyester cloth impregnated with a special gel, immersed in a hot saline solution.

Main Results:

  • The device's tip maintains its temperature after soaking in hot saline.
  • The DisePad was utilized in 364 laparoscopic procedures.

Conclusions:

  • The DisePad effectively visualizes, separates, and cleans anatomical structures during laparoscopy.
  • The device demonstrated utility without causing thermal lesions, tearing, hemorrhage, or visceral perforation.
