[Multi-instruments cannula: a new concept of laparoscopy].

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.
