Endoscopic treatment system
First Claim
1. An endoscopic treatment system comprising:
- a first insertion instrument;
a second insertion instrument into which the first insertion instrument is inserted;
an observation device included in either the first insertion instrument or the second insertion instrument and used to observe a living-body tissue;
a clamping and lifting member that is included in the first insertion instrument and that has a clamping member which clamps the living-body tissue that is an object of treatment, and a lifting member which lifts the living-body tissue though bending;
a tissue retainer member that is included in the second insertion instrument and that controls the lifting of a peripheral tissue of the living-body tissue clamped and lifted by the clamping and lifting member included in the first insertion instrument;
a ligating member that ligates the living-body tissue; and
a resecting member that resects the living-body tissue at a position between a region ligated by the ligating member and a region clamped by the clamping and lifting member;
wherein the inserting sections of the first and second insertion instruments which are inserted into a living-body duct are formed with flexible members;
the clamping member is a pair of clamp forceps that is inserted in a treatment instrument passage channel lying through the first insertion instrument;
a lateral hole is formed in the lateral side on the outer periphery of the second insertion instrument; and
a slit is formed in the lateral side on the outer periphery of the second insertion instrument opposing the lateral hole.

Abstract
An endoscopic treatment system is designed to suture or resect a lesion while ensuring the ease of insertion into a deep region in the large intestine. The endoscopic treatment system comprises an endoscope and a therapeutic instruments insertion aid into which the endoscope is inserted. The endoscopic treatment system further comprises: a pair of clamp forceps that clamps and lifts a living-body tissue; a lateral hole formed in the therapeutic instruments insertion aid and used to control the position of the living-body tissue clamped and lifted by the pair of clamp forceps or to control the lifting thereof; a ligature used to ligate the living-body tissue whose position or lifting is controlled by the lateral hole; and a cutter used to resect the living-body tissue at a position between a region ligated with the ligature and a region clamped and lifted with the pair of clamp forceps.

20. An endoscopic treatment method comprising the steps of:
-
inserting an endoscope into an intended region in a living body'"'"'s duct; inserting a first insertion instrument mounted on the outer surface of the endoscope; exchanging the endoscope for a second insertion instrument; clamping a living-body tissue positioned in a lateral hole formed in an outer periphery of an insertion part of the first insertion instrument; lifting the clamped living-body tissue so as to draw it into the lateral hole using the second insertion instrument; ligating the lifted living-body tissue using the ligating member; resecting the ligated living-body tissue at a position between the ligated region of the living-body and the clamped region thereof; and removing and collecting the resected living-body tissue together with the second insertion instrument.

21. An endoscopic treatment system comprising:
-
a first insertion instrument; a second insertion instrument into which the first insertion instrument is inserted; an observation device included in either the first insertion instrument or the second insertion instrument and used to observe a living-body tissue; a clamping and lifting member that is included in the first insertion instrument and that has a clamping member which clamps the living-body tissue that is an object of treatment, and a lifting member which lifts the living-body tissue though bending; a tissue retainer member that is included in the second insertion instrument and that controls the lifting of a peripheral tissue of the living-body tissue clamped and lifted by the clamping and lifting member included in the first insertion instrument; a ligating member that ligates the living-body tissue; and a resecting member that resects the living-body tissue at a position between a region ligated by the ligating member and a region clamped by the clamping and lifting member; wherein the second insertion instrument includes a bending mechanism. - View Dependent Claims (22, 23, 24)

25. An endoscopic treatment system comprising:
-
a first insertion instrument; a second insertion instrument into which the first insertion instrument is inserted; an observation device included in either the first insertion instrument or the second insertion instrument and used to observe a living-body tissue; a clamping and lifting member that is included in the first insertion instrument and that has a clamping member which clamps the living-body tissue that is an object of treatment, and a lifting member which lifts the living-body tissue through bending; a tissue retainer member that is included in the second insertion instrument and that controls the lifting of a peripheral tissue of the living-body tissue clamped and lifted by the clamping and lifting member included in the first insertion instrument; a ligating member that ligates the living-body tissue; and a resecting member that resects the living-body tissue at a position between a region ligated by the ligating member and a region clamped by the clamping and lifting member; wherein the second insertion instrument has puncturing needle and ligature passage channels through which respective puncturing needles and ligatures are passed; a receiving member located in more distant end of the second insertion instrument than the puncturing needle and ligature passage channels are, and formed with a bar-like or plate-like member; and arm members that link the distal end of the second insertion instrument and the receiving member. - View Dependent Claims (26)

27. A treatment device, comprising:
-
an insertion portion having a lumen into which an insertion instrument including a clamping member is inserted; a tissue retainer member which is provided in the insertion portion and which controls the lifting of a peripheral tissue of the tissue clamped and lifted by the insertion instrument; a slit provided in an area opposite to the tissue retainer member with the center of the lumen therebetween, the slit permitting the distal end of the insertion instrument to be bent away from the center of the lumen in order to lift the tissue; a ligating member which ligates the tissue; and a resecting member which resects the tissue at a position between a region ligated by the ligating member and a region clamped by the insertion instrument.
