A new insufflation needle with a special optical system for use in laparoscopic procedures

Area of Science:

• Minimally Invasive Surgery
• Surgical Instrumentation
• Laparoscopy

Background:

• Traditional insufflation needles are inserted blindly, posing risks of visceral or vascular injury.
• Accidental insufflation into the properitoneal space is a known complication.
• Improving safety in laparoscopic procedures remains a key focus in surgical innovation.

Purpose of the Study:

• To introduce a novel insufflation needle with an integrated optical system.
• To evaluate the potential of direct visualization during abdominal wall access in laparoscopy.
• To reduce complications associated with blind needle insertion.

Main Methods:

• Development of a new insufflation needle featuring a transparent, conical tip.
• Integration of an optical system allowing endoscope attachment.
• Utilization of a video camera for real-time monitoring of needle progression on a monitor.

Main Results:

• Direct visualization of the abdominal wall during perforation is achieved.
• The risk of damaging vessels and intra-abdominal organs is significantly reduced.
• Accurate needle tip positioning prevents insufflation into the properitoneal space.

Conclusions:

• The new optical insufflation needle enhances safety in laparoscopic procedures.
• Direct vision during abdominal access minimizes iatrogenic injury.
• This instrument represents a significant advancement in laparoscopic surgical safety.
