Robotic Assisted Partial Nephrectomy (RAPN)

Partial NephrectomyThis is the original model that the lab created. The procedure is for the event of a renal tumor to provide a technique to remove the mass while sparing as much of the kidney as possible. Consequently, this procedure is very delicate and requires an experienced surgeon. The surgeon must remove the tumor while avoiding positive margins (any tumor left on the kidney) while the renal artery is clamped.

Percutaneous Nephrolithotomy (PCNL)

Percutaneous Nephrolithotomy (PCNL)This procedure is performed to remove kidney stones from the body when they cannot pass on their own. The procedure is minimally invasive where a scope is inserted through a small incision in the back to remove the stones. This surgery is for kidney stones that are often much larger and not able to pass on their own. Our model allows surgeons to practice accessing the proper region of the kidney’s urinary collecting system based on where the stone is located.

Inflatable-Penile Prosthetics

Inter Penile ProstheticsThis procedure is for patients suffering from erectile dysfunction due to a number of causes. In the event that all other treatments have failed (medications, injections therapy etc.) the patient can opt to undergo this surgery. The procedure consists of two balloon apparatuses that are placed in each respective corpora cavernosa, a pump apparatus that is placed in the layers of the scrotum, and a fluid reservoir that is placed infrapubicly. The device works by using the scrotal pump to inflate the corporal balloons in the corpora which simulates penile erection.

Robotic Nerve Sparing Radical Prostatectomy (NSRP)

Robotic Nerve Sparing Radical Prostatectomy (NSRP)This procedure is for patients with clinically localized prostate cancer to provide patients with a safe and minimally invasive technique for removal of the prostate gland. During the procedure, the goal is to preserve as much of the surrounding nerve structures as possible. The nerve structures are responsible for many penile related functions; damage to which can lead to penile impotence and urinary incontinence.

Coronary Artery Bypass Simulation (CABG)

Coronary Artery Bypass Simulation (CABG)
This procedure is for patients who are suffering from severe coronary artery disease leading to blocked coronary arteries and ultimately an ischemic heart. The Coronary Artery Bypass Procedure is an extremely invasive procedure that commonly involves a full sternotomy and cardioversion. Training for this procedure is currently limited to models that are expensive, anatomically inaccurate and/or do not fully replicate human tissue. Our model is a customizable full procedural simulation of the surgery which offers on-pump and off-pump approaches.

Cholecystectomy

CholecystectomyThis procedure is for the removal of the gallbladder in the case of gallstones which block the biliary system. The procedure is often performed laparoscopically through four small ports through the abdomen rather than one large incision. Our model allows for the introduction and practice of laparoscopic surgery to medical students in their third year during their surgical rotation.

Kidney Transplant

Kidney TransplantThis procedure is in the case of renal failure necessitating a patient to receive a new kidney from a donor. Our model allows for a patient-specific procedure to allow the surgeon to practice harvesting the donor kidney.

Minimally Invasive Robotic Hysterectomy

Minimally Invasive Robotic HysterectomyThis procedure is in the case of renal failure necessitating a patient to receive a new kidney from a donor. Our model allows for a patient-specific procedure to allow the surgeon to practice harvesting the donor kidney.

Mechanical Testing

Mechanical TestingIn order to make our models as life-like as possible, we use various mechanical testing techniques to determine the mechanical properties of both porcine and cadaveric tissues from the respective organ of interest. The tests include but are not limited to tensile stress vs strain, perfusion forces, and compression forces. Using this data, we can then modify our hydrogel material to match the properties of the respective tissue.

Liver Transplant

Liver TransplantAcute or chronic liver failure indicates that it is impossible for the liver to function well enough to keep the body alive, requiring an organ transplant. A liver transplant operation is comprised of two parallel surgeries that replace a patient's diseased liver with a whole or partial healthy liver from either a live or a deceased donor. Our lab aims to simulate the complex donor liver surgery by replicating the anatomy of the donor's liver, gallbladder, and blood vessels including the hepatic artery, portal vein, and hepatic vein.

Knee Model

Knee ModelThe purpose of this model is to replicate a variety of knee based surgeries (ACL, meniscal repairs, total knee replacements, etc.). The project utilizes mechanical testing to verify all the components of the model to ensure that they respond to stresses and strains in a similar manner as human knee components. The developed tissues are then constructed in a way that maintains their integrity and demonstrate the true anatomy of a human knee.

Head-Mounted Eye Tracking: Gaze and Cognitive Load

Head-Mounted Eye Tracking: Gaze and Cognitive LoadThis project focuses more on the surgeon and less on the procedure. The goal of the project is to create a training-data set of surgical objective performance metrics (as measured by the Da Vinci Surgery Simulator) and pupil metrics (as measured by pupil head-mounted eye tracking system) from trained and untrained subjects.

Major Vascular Injury

Team DebriefThis project mimics a retroperitoneal lymph node and mass dissection. The goal of this model is to simulate the entire operating room environment from the surgeons, the anesthesiologists, the scrub techs, and the nurses. The model simulates a major vascular injury forcing the team to work together to control the situation. The project aims to analyze how the operating room team communicates with each other in the event of a major complication. After the procedure, the team debriefs through a guided discussion on how they performed.

Airway Model

Airway Model

The goal of this project is to develop an anatomically accurate model of the airway, venous system, and surrounding tissues for training purposes. The model is designed for airway access and central line placement procedures including cricothyroidotomy, tracheostomy, intubation, subclavian vein central line placement, and internal jugular vein central line placement.
