Custom Prostate Model

Eliminate cadaver labs for device training

 “Just so you know, we have moved to complete model simulation training at surgeon’s hospitals the day before first cases with the ultrasound-able prostate model and it has decreased the learning curve and improved the first day of cases dramatically. To be honest, I hope we never use cadavers again.”

The Challenge:

Procept BioRobotic’s professional education manager wanted an anatomical surgical training model to train urologists to perform their Aquablation therapy for the treatment of benign prostatic hyperplasia (BPH). The model had to work using ultrasound visualization. The prostate had to be operable using water ablation. The anatomy needed to be accurately represented and the softness of the simulated tissue responds to the procedure in the most lifelike manner possible to provide the urologist with experience to rival and surpass an experience with a cadaver. Procept BioRobotics had planned an aggressive international training curriculum so convenience and portability were paramount.


Model Definition:

A first hurdle was creating ultrasound-able, consumable, replaceable prostates that worked with their hydroblation device. Second, we had to create a men’s health anatomy platform that would accommodate all the steps of the BPH procedure.


Model Development:

Pulse MDM started by providing Procept BioRobotics with sample prostates made from different material recipes to test & evaluate with both their water ablation catheter and a rectal ultrasound probe. After several rounds of refinement, Procept and Pulse MDM developed a material that looked realistic under ultrasound imaging. Then we dialed in the formulation to make sure they could be realistically ablated using their water ablation technology.

Once we found success with the prostate materials, a model needed to be crafted to represent the life-like clinical challenges of the Aquablation procedure. The proper positioning of the Trus ultrasound probe in relation to the ablation catheter is critical to the procedure.  So, the rectum and the urethra had to interact with the devices in a clinically relevant way.

Not only did we need to accommodate the correct positioning of the two devices we needed to provide enough leeway in the model in order for the physician to do the procedure incorrectly in order to learn what adjustments they would need to implement during surgery. The rectum was designed to accept a rectal probe. The penis was designed to accept their urethral catheter. The model is filled with fluid to facilitate ultrasound. And the prostate is held in place mechanically with a simple holder that ensures the prostate is presented in the correct position and makes prostate replacement a snap.


Model Production:

Pulse MDM designed a model as compact as possible to make the model both portable and less costly to ship around the world. Pared down to the absolute smallest footprint the model provides the necessary surrounding anatomy but still fits into a compact case. Every model is equipped with a small box of replacement prostates, so each physician gets a fresh trial with the device. In addition, each model is fitted into a custom foam insert which protects it inside the case while in transit.


Model Benefit:

The custom prostate model allows more trial, more confidence gained in the product, more procedure-adoption. After the surgeon performs the procedure, they can examine their results immediately. Each participant can see how well they ablated the prostate, get coaching from the Medical Device team, and try again.

And just imagine, no more cadaver labs! 

  • This means no need to fly urologists to your lab.
  • No need to train the urologist without their support team.
  • No need to go through the hassle to procure cadavers and arrange costly lab space.
  • Models come without geographic limitations or cultural objections.
  • Models offer no surprises like discovering missing anatomy.
  • There are no problems training in the hospital OR.
  • No biosafety risks, no mess, no complicated disposal protocol, no recurring expense.
  • Models provide clinically realistic, convenient, and cost-effective professional clinical training anywhere around the globe.

As if all those benefits are not enough, Pulse MDM can also create an endless supply of pathology variations for more varied clinical discussions and practice. That’s not something that cadaveric specimens can ever offer. The custom anatomy model beats the cadaver 11 to 0!

Custom Ultrasound-able Prostate Model

BPH Procedure Overview:

Benign prostatic hyperplasia (BPH) Overview. BPH, also called prostate gland enlargement, is a common urological condition men experience as they get older. An enlarged prostate gland can cause uncomfortable symptoms, such as blocking the flow of urine out of the bladder and urinary tract or kidney problems. Aquablation therapy offers clinicians peace of mind that comes with consistency and precision as compared to alternative BPH treatments.
