Nerve Repair Training Model

Take all your nerves with you

The Challenge:  

Integra LifeSciences needed a model to foster continued interaction with their team and target audience and provide more meaningful professional education. Their goal is to ignite clinical decision-making discussions surrounding nerve injuries. Nerves typically fall into a few patterns of injury: Failed repair from a previous surgery, partial transection of a nerve, complete transection of a nerve, and injured nerve with nowhere to re-attach. The problems Integra wanted to address with their custom model were the following: 

  • Eliminating the use of cadavers due to cost and single use. 
  • Limiting clinician travel by taking the demo on the road. 
  • Increasing the number of demos by eliminating the necessity for lab access. 
  • “Anchoring discussions from concept to concrete” by using a hands-on model. 


Model Design:  

Nerve injuries can happen anywhere in the body, but injuries remain the same.  Pulse MDM designed a model that would encourage clinical conversations to surface in a multitude of locations by using cards printed with images of hands, feet, elbows, etc. to provide context. Printed cards are exponentially less costly to produce than three-dimensional modeled anatomy. Our team is always working to keep costs as low as possible for our clients.  


Model Development:  

The modeled nerves are specially made to be soft and flexible, but not stretchy to be more in keeping with real nerves. Pulse MDM planned to replicate the 4 major types of nerve injury: stump neuroma, neuroma in continuity, partial transection, and complete transection. The contextual art was selected by the client and rendered by Pulse MDM. To allow infinite placement options for the nerves, Pulse opted to use suction cups with clips to hold the nerves anywhere on the anatomy cards. 


Model Solution:  

Pulse created a model that provides the clinician with several choices. To start, a clinician will select an anatomy card to insert into the fixture. From there, the nerves that are clipped to suction cups are attached at clinically relevant locations on the cards. The flexibility of the repositionable suction cup clips allows the model to represent different gap lengths for the full nerve transection by adjusting the distance between the ends of the transected nerves using the suction cup clips. The type of nerve damage and the location allow for limitless clinically relevant conversations and nerve repair practice. The model allows for increased consistency from interaction to interaction, and serve to help reps walk through the procedural sequence with clinicians for a thorough training experience. The models have even been used to create video content for continued outreach and clinical education. 


Procedure Overview: 

Surgical nerve repair is when a clinician explores an injured nerve and removes the injured tissue or scarring from the nerve endings. Once that is complete, if there is enough length, a nerve can be directly reconnected. If there is not enough length because a larger amount of tissues had to be removed, collagen conduits can be used to support natural nerve generation.
