Are reusable holmium laser fibers an accessory or a consumable?

Accessory. A holmium laser fiber is an optical accessory used in medical devices, typically used in laser surgery to transmit laser energy to the surgical site. Because of its durability and ability to be reused, it can be considered an accessory to a medical device. In contrast, consumables are parts of medical devices that need to be replaced frequently, such as surgical blades and disposable syringes.
