An endoscopic instrument includes an inner elongated instrument member that fits the bore of an outer elongated instrument member. The outer elongated instrument member includes a slot through which a surgical sheet material can be pulled so as to furl the material within the instrument. The slot can vary in length and width accommodating various surgical sheet material sizes. The slot can also be open ended or closed and its length and width can be varied accommodating different sizes and thicknesses of sheet material. The inner instrument member can include a flag that can be furled about the distal end portion of the inner instrument member and for attachment to the sheet of surgical material. The outer instrument member includes an articulating end portion that can be moved to deflect the end portion of the inner instrument member such as when the flag is unfurled inside a patient's body cavity.

Instrumentation for endoscopic surgical insertion and application of liquid, gel and like material

An endoscopic instrument includes an inner elongated instrument member that fits the bore of an outer elongated instrument member. The inner instrument member carries a flag that can be furled about the distal end portion of the inner instrument member. A sheet of surgical material to be dispensed into a patient's body cavity can be attached to the flag. The outer instrument member includes an articulating end portion that can be moved to deflect the end portion of the inner instrument member such as when the flag is unfurled inside a patient's body cavity.

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.

A method and apparatus for laparoscopic insertion and application of a sheet like material (such as an adhesion barrier) and the like products enables the laparoscopic surgeon to utilize large and full size sheets of Interceed (3'.times.4') in abdominal (including pelvic) surgery. In laparoscopy surgery of the abdomen (including pelvis), all instrumentation and all surgical products must be introduced through 'ports' consisting of valved sleeved or tubes. To properly and efficiently introduce and apply a large or full size sheet of sheet like material, the present invention provides a method and apparatus for grasping and furling the sheet and then unfurling, releasing and applying it after passage into the patient's abdominal cavity. The instrument consists of an operational grasping and furling portion which is rotated to furl the sheet like material. It is then 'backloaded' or drawn into a tubular portion of the instrument, an inserter sheath for passage through the valved 'port'. Once the sheet like material is in the abdominal cavity it is unfurled. The grasping portion of the instrument provides for proper and easier alignment and then application of the unfurled sheet. Additional flexibility is achieved by an articulation mechanism which allows horizontal movement of the grasping/furling element to produce an angle in the instrument body.

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.
