Method for use in intra-abdominal surgery
First Claim
1. A method for use in intra-abdominal surgery, comprising the steps of:
- inserting an endoscope through a natural body opening into a natural body cavity of a patient;
inserting an endoscopic type incising instrument into said natural body cavity along a passage established by said endoscope;
manipulating said incising instrument from outside the patient to form a perforation in an internal wall of said natural internal body cavity;
moving a distal end of said endoscope through said perforation;
using said endoscope to visually inspect internal body tissues in an abdominal cavity of the patient;
executing a surgical operation on said internal body tissues by manipulating an endoscopic surgical instrument passed along said endoscope through said natural body opening, said natural body cavity and said perforation into said abdominal cavity;
withdrawing said surgical instrument and said endoscope from said abdominal cavity through said perforation;
closing said perforation; and
withdrawing said endoscope from said natural body cavity.

Abstract
A method for use in intra-abdominal surgery comprises the steps of inserting a tubular member into a natural body cavity of a patient through a natural body opening, manipulating the tubular member from outside the patient so that a distal end of the tubular member engages a wall of the natural body cavity, and forming a fluid tight connection between the distal end of the tubular member and the wall. Additional steps of the method include inserting an incising instrument through the tubular member upon insufflation of the abdominal cavity, manipulating the incising instrument from outside the patient to form a perforation through the surface of the wall, and moving a distal end of an endoscope through the tubular member and through the perforation. The endoscope is used to visually inspect internal body tissues in an abdominal cavity of the patient. Subsequently, a surgical operation is executed on the internal body tissues of the patient by manipulating an endoscopic surgical instrument passed along the endoscope through the natural body opening, the natural body cavity and the perforation into the abdominal cavity. After the intra-abdominal operation, the surgical instrument and the endoscope are withdrawn from the abdominal cavity through the perforation, the perforation is closed, and the endoscope and the tubular member are withdrawn from the natural body cavity.

11. A method for use in intra-abdominal surgery, comprising the steps of:
-
inserting a tubular member into a natural body cavity of a patient through a natural body opening; manipulating said tubular member from outside the patient so that a distal end of said tubular member engages a wall of said natural body cavity; forming a fluid tight connection between said distal end of said tubular member and said wall; inserting a hollow needle through said tubular member and through a surface of said wall encircled by said distal end of said tubular member; insufflating the abdominal cavity by forcing pressurized gas through said needle and into the abdominal cavity; upon insufflation of the abdominal cavity, inserting an incising instrument through said tubular member; manipulating said incising instrument from outside the patient to form a perforation through said surface of said wall; moving a distal end of an endoscope through said tubular member and through said perforation; using said endoscope to visually inspect internal body tissues in an abdominal cavity of the patient; executing a surgical operation on said internal body tissues by manipulating an endoscopic surgical instrument passed along said endoscope through said natural body opening, said natural body cavity and said perforation into said abdominal cavity; withdrawing said surgical instrument and said endoscope from said abdominal cavity through said perforation; closing said perforation; and withdrawing said endoscope and said tubular member from said natural body cavity. - View Dependent Claims (12, 13, 14, 15, 16, 17)
