Custom Laparoscopic Training Model

The Challenge:

This hernia mesh procedure requires that the surgeon measure the hernia defect on the exterior of the abdomen after insufflation by passing needles from the internal cavity to the exterior skin at the extents of the defect. The distance between the needles can be used to determine the size of the defect so the surgeon can calculate the size and shape of the mesh required to correct it.

This hernia treatment method required the model to include the following features:

• The model distends realistically during insufflation and return to normal afterward
• The soft tissue abdominal plate continues to hold air and pressure when compromised by needles and a large trocar
• The mesh tacks seats into the tissue realistically without any bounce back that would create gaps between the tack and the tissue

Model Design:

In addition to the unique challenges required by the procedure Pulse MDM added additional features:

• The abdominal plate be durable for long term use but easily replaceable when required
• The torso model be supported in a manner to position the patient supine or laterally
• The trocar ports be located on flexible skin to facilitate more instrument range of motion
• Sculpted abdominal defect on the inside of the plate for surgeons to measure

Model Development:

Several models were made to solve the technical challenges of holding air on a removable abdominal plate part that would also be punctured with a large trocar. Pumps were sourced and tested. A lower cost scope replica was developed to save cost and to work with a portable screen to provide a realistic surgical view without requiring an operating room

Model Solution:

This insufflatable laparoscopic model facilitates an abdomen that changes curve while being insufflated into a distended position. It endures repeated punctures while surgeons measure the hernia defect in the abdominal wall for treatment. Designed to accept punctures without losing pressure the fasteners and staples ‘seat’ in the model just like in live tissue. The model included a pump, lights, scope with camera & USB connection to a laptop, all for training surgeons on emerging procedures in any setting. This model was produced to be sent to locations all over the world in the place of expensive & inconvenient animal or cadaver labs.

Although this custom model is not available for sale to the public, we are delighted to make you a version that is specific to your unique medical device and procedure. Please use this link to start the process of receiving a model concept; a visual representation of how clinicians and patients will experience your product and procedure. Pulse MDM does not charge for model concepts or the conversations around them so there is no risk to see how we can help you to tell your story in the most engaging and memorable way possible.

Procedure Overview:

Laparoscopic (minimally invasive) hernia repair uses a laparoscope, a thin, telescope-like instrument that is inserted through a small incision at the umbilicus. The laparoscope is connected to a tiny video camera, that projects an “inside view” of the body onto television screens in the operating room.

The abdomen is inflated with a carbon dioxide, which creates space to allow the doctor to view internal structures. The peritoneum is cut to expose the weakness in the abdominal wall. Mesh is placed on the inside to cover the defects in the abdominal wall and strengthen the tissue.

After the procedure is completed, the small abdominal incisions are closed with a stitch or two or with surgical tape. Within a few months, the incisions are barely visible.

Benefits of laparoscopic hernia surgery include three tiny scars rather than one larger incision, less pain after surgery, a quicker return to work within days of the surgery.
