Instrument guard and reusable medical device employing same

An instrument guard for a MIS medical device includes an attachment portion and an instrument holding portion. The attachment portion is removably attachable to a containment tube of a medical device used for minimally invasive surgery. The instrument holding portion is used to contain and insulate surgical instruments used for the procedure. The instrument guard may be removed after use, exposing the surgical instruments and allowing for cleaning thereof, by washing, brushing, ultrasonic cleaning and visual inspection. A clean instrument guard is then placed on the device, enabling the device to be reused in another procedure.
