Reconstructive Laparoscopic Procedure for Reduced Tissue Trauma Laparoscopic partial nephrectomy is a technically challenging procedure involving reconstruction of fragile tissue that has to be accomplished in a time-sensitive manner. This technology is a parenchymal apposition mechanism (PAM) that may be used for laparoscopic apposition of the tissue of the kidneys or other organs. It consists of mechanical hooks that close and hold parenchymal defects. This can simplify and expedite reconstructive laparoscopic procedures, resulting in reduced tissue trauma and decreased ischemic times compared to standard laparoscopic techniques in current practice.
Laparoscopic Surgery Technology Reduces Ischemic Cross-Clamp Time • This technology helps laparoscopic surgeons close parenchymal defects in an efficient manner, with reduced ischemic time and less traumatic tissue injury. • It is a device that may be used for laparoscopic reconstruction. • Theoretically allows the surgeon to engage the hooks of the PAM device prior to cross-clamping of the renal vasculature and excising the tissue. This technique may significantly decrease ischemic cross-clamp time.
Applications: This technology could aid in the partial resection or reconstruction of any organ to treat cancer or trauma, including the following organs: • Kidneys • Liver • Uterus • Spleen
Advantages: • Reduced ischemic time and less traumatic tissue injury during surgery. • No significant difference between the prototype and standard laparoscopic materials in terms of closing time, mean pressures achieved in closure, and parenchymal trauma. • Technique may significantly decrease ischemic cross-clamp time.
