Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Area of Science:

  • Surgical innovation
  • Minimally-invasive surgery
  • Medical device design

Context:

  • Traditional laparoscopy often requires multiple abdominal ports, increasing risks of organ injury, infection, and hernia.
  • Current multi-port approaches are increasingly viewed as overly traumatic and less aligned with 'minimally-invasive' principles.
  • There is a growing need for advanced surgical tools that minimize patient trauma and improve outcomes.

Purpose:

  • To design and evaluate a novel cannula device for single-port abdominal surgery.
  • To overcome the limitations of traditional multi-port laparoscopy by consolidating instruments and optics into one port.
  • To explore the potential for robotic integration with single-port systems.

Summary:

  • A new 4 cm diameter, 5 cm long cannula with a five-opening lid (for telescope and instruments) and insufflation tap was developed.

  • The device was tested in a simulator and subsequently in five pigs for cystostomy and nephrectomy procedures.
  • Results demonstrated optimal device dimensions, excellent visualization, hermetic sealing, and ease of instrument manipulation and suturing.

    • Impact:

    • This single-port system reduces abdominal wall trauma, potentially decreasing complications associated with multiple incisions.
    • The device offers a more streamlined and less invasive surgical approach, aligning with modern surgical standards.
    • It presents significant potential for future robotic integration, promising to revolutionize surgical practice.
