Abstract

A method and apparatus for endoscopic surgical insertion and application of a liquid, gel or like medicinal material enables a surgeon to utilize various delivery tubes with differing spray patterns to apply the desired material. In endoscopic surgery of the body cavity (including chest cavity and pelvis), instrumentation and surgical products are typically introduced through 'ports' consisting of valves, sleeves or tubes. To properly and efficiently introduce and apply liquid, gel or like medicinal material, the present invention provides a method and apparatus for dispensing the desired material with a desired pattern or spray. The instrument consists of an elongated instrument body that can receive one of a selected flexible delivery tubes (of a kit of tubes) having a distal end with a nozzle. The instrument body rotates at its distal end, thereby rotating the dispensing tube. The selected nozzle of the selected dispensing tube can be positioned to dispense with a desired spray pattern into any rotational position of the patient's body cavity. A syringe (or a syringe with an extension tube can be used to push gel, liquid medicine or the like through the dispensing tube to the distal end thereof.
