Method of securing a cavity using a rigid sheath with transparent cap
First Claim
1. A method of securing a cavity in a living body, comprising the steps of:
- incising a small portion of the body so as to form a small incised portion;
introducing an assembly of a rigid sheath with a rigid transparent cap and an endoscope into the small incised portion between a first tissue and a second tissue, said rigid transparent cap being at an end portion of the rigid sheath and said rigid transparent cap including an opening formed at a distal end thereof for enabling direct observation to be performed by the endoscope through the opening; and
detaching the second tissue from the first tissue using the rigid sheath with the rigid transparent cap.

Abstract
An endoscopic sheath comprising a tubular sheath section having a distal end portion and a hole which extends throughout the length of the sheath section and through which an insert section of an endoscope having observation device can be passed, at least the distal end of the distal end portion opening, and at least the distal end portion being formed of a transparent material, and positioning device for positioning the insert section of the endoscope in the sheath section so that at least part of the distal end portion of the sheath section can be within the view range of the endoscope. A method of securing a cavity includes introducing the sheath and transparent distal end portion into an incision and detaching first and second tissues using the sheath and transparent distal end portion.

-
incising a small portion of the body so as to form a small incised portion; introducing an assembly of a rigid sheath with a rigid transparent cap and an endoscope into the small incised portion between a first tissue and a second tissue; and detaching the second tissue from the first tissue by moving an edge of the rigid transparent cap from side to side or by advancing the edge of the rigid transparent cap, while performing observation through the endoscope. - View Dependent Claims (10, 11)

12. A method of securing a cavity in a living body, comprising the steps of:
-
incising a small portion of an abdominal wall of the body such that only a peritoneum remains for forming a small incised portion; introducing an assembly of a rigid sheath with a rigid transparent cap and an endoscope into the small incised portion, said rigid transparent cap being at an end portion of the rigid sheath and said rigid transparent cap including an opening formed at a distal end thereof for enabling direct observation to be performed by the endoscope through the opening; and detaching the abdominal wall from the peritoneum using the rigid sheath with the rigid transparent cap or an instrument to form a cavity between the abdominal wall and the peritoneum. - View Dependent Claims (13)
