Abstract: Surgical ventilating apparatus for use in laser surgical techniques. The surgical ventilating apparatus comprises a tubular body having an inner, hollow, flexible metallic member and an outer layer formed of a heat-resistant material. Preferably, the inner member is formed of molybdenum and the outer layer is formed of a heat resistant coating, such as an oxide of a metal, an expanded or foamed silica or quartz, and the like. A connector adapted to be connected to one end of the tubular body enables the tubular body to be connected to ventilating equipment for controlling the respiration of the patient during surgery.

Abstract: Surgical ventilating apparatus for use in laser surgical techniques. The surgical ventilating apparatus comprises a hollow, flexible, tubular body formed of a heat-resistant material, such as an oxide of a metal, an expanded or foamed silica or quartz, and the like. The tubular body is formed so as to resist vibration when disposed within the trachea of a patient caused by the high velocity of air flowing therethrough. In one embodiment, at least one rod-like member is embedded within the tubular body to provide a degree of rigidity thereto. In another embodiment, the end of the tubular body is flared to reduce vibration of the tubular body. A connector adapted to be connected to one end of the tubular body enables the tubular body to be connected to ventilating equipment for controlling the respiration of the patient during surgery.
