E-Beam vs. Gamma Sterilization

May 23, 2013 2:39 pm | by Larry Nichols, COO, and Bob Starrett, CTO, NUTEK Corporation | NUTEK Corporation | Comments

Many of the sterilization issues concerning gamma and electron beam radiation are the same. This point is supported by the fact that both technologies are governed by the same ISO standards when applied to medical device sterilization—ISO 11137 and ISO 13409. Both technologies have been proven effective at sterilization and are accepted worldwide.

Replacing the Cadaver for Surgical Students

May 22, 2013 4:06 pm | by Kasey Panetta, Managing Editor, ECN | Comments

Surgical simulators are an ideal solution for training surgeons with minimal risk to patient health and safety. This is particularly important when surgeons train for procedures utilizing arthroscopy because it requires the surgeon to perform the surgery while looking at a camera screen instead of the patient. This necessitates extensive training to ensure the doctor is an expert in the method.
