Abstract: The invention, referred to commercially as the “Endosleeve,” is a heat- and fire-resistant holster, holder or sleeve to secure and protect an endoscope during a medical or surgical operation. The Endosleeve consists of several components: a clamp or other mechanism that attaches the Endosleeve to the operating table; flexible tubing, which connects the clamp to the actual holster in which the endoscope is placed and which allows the physician to move the Endosleeve as necessary; and a holster that is fire and heat resistant, protecting the physician and patient from operating room fires. There is currently no such safety device to safely hold an endoscope during a medical or surgical procedure.
