Medtronic METRx II Tubular Microdiscectomy Retractor System

The Medtronic METRx II is a tubular retractor system designed to provide minimally invasive access for microdiscectomy and other spinal procedures. This surgical instrumentation is utilized by orthopedic and neurosurgeons to create a surgical corridor with minimal tissue disruption, which is a key aspect of minimally invasive spine surgery (MISS).

The system operates by using a series of sequential dilators to gently separate muscle fibers rather than cutting them. A tubular retractor is then placed to maintain access to the surgical site. This technique is intended to reduce muscle trauma and support patient recovery. The METRx II system is a staple in operating rooms for a variety of spinal decompression procedures.
