Laparoscopic surgery

Problem Addressed

Minimally invasive laparoscopic surgical procedures generally require a surgeon to operate in a highly constrained space within a patient’s body, such as the abdominal cavity, where other organs and tissues may obstruct access to the surgical site.  Typically during an abdominal laparoscopic surgery, a surgeon inserts a trocar (a small tube) through a small incision in the abdominal wall, inflates the abdomen with gas, and works with an assistant whose primary job is to hold the camera and lights as well as retracting organs.  This results in two people operating in an already small workspace, making it even more challenging to allow field visualization and proper angle for surgical maneuvers.  Hence, there remains a need for improved surgical tools to simplify laparoscopic procedures. 


Laparoscopic surgery is a minimally invasive surgery that provides certain advantages over other more invasive procedures.  Small laparoscopic surgical incisions often require less time to heal, are less painful, and leave smaller scars.  This invention presents a collapsible scaffold that can be deployed to a laparoscopic surgical site through a trocar and can expand to assist the surgical procedures in a variety of ways, such as providing a surface for organ retraction within a body cavity or by providing a rigid platform upon which to secure retracted organs or surgical tools such as lights, cameras, and so forth.  This device can reduce or eliminate the need for a highly trained assistant during surgery, reduce the number of incisions required, shorten the duration of the surgery, and improve overall outcome. 


  • Provides a platform for organ retraction
  • Eliminates/reduces the need for a highly trained assistant
  • Reduces the number of incisions required
  • Shortens the duration of surgery
