FIGS. 1 and 2 show a hood 1 for an endoscope according to a first embodiment of the invention. The hood 1 for an endoscope comprises a cap part 2 defining a cavity 1 a which in a preferred implementation is approximately cylindrical and transparent. The hood 1 further comprises an endoscope mounting part 5 (alternatively referred to herein as a “fixing part”) which is approximately cylindrical and detachably fix to the hood 1 on the end portion of an insertion part 4 of an endoscope 3. The cap part 2 is approximately cylindrical with the outer diameter 18 mm, the inner diameter 16 mm and the length 14 mm. The endoscope mounting part 5 is approximately cylindrical with the outer diameter 13 mm, the inner diameter 12 mm and the length 10 mm.
a cap part defining a cavity and having an opening;
a flexible tube having a distal end which is fixed to said cap part and communicating with the cavity of said cap part through the opening, and a proximal end through which an endoscopic treating instrument can be removably inserted into the flexible tube without connecting a tube arranged inside the endoscope thereto;
wherein said flexible tube is adapted to be arranged outside the endoscope when said hood is attached at the distal end of the endoscope;
wherein the cap part includes a side wall and a connecting wall which connects between the side wall and the fixing part, and outwardly extends from the fixing part; and
wherein the opening is formed on the connecting wall.
2. The hood according to claim 1, wherein said cap part and said fixing part are substantially cylindrical to be fitted on the distal end of said endoscope which is also substantially cylindrical.
a flexible tube having a distal end which is fixed to said cap part and communicating with the cavity of said cap part;
wherein said flexible tube is adapted to be arranged outside an endoscope
when said hood is attached at the distal end of the endoscope;
19. An endoscopic hood system comprising:
a fixing part for fixing said cap part to a distal end of an endoscope;
a flexible tube having a distal end which is fixed to said cap part and communicating with the cavity of said cap part through said opening, and a proximal end; and
an endoscopic treating instrument being removably inserted into said flexible tube through said proximal end without connecting a tube arranged inside the endoscope thereto;
wherein said flexible tube is adapted to be arranged outside an endoscope when said hood is attached at the distal end of the endoscope;
wherein the cap part includes a side wall and a connecting wall which connects between the side wall and the fixing part and outwardly extends from the fixing part; and
20. An endoscopic hood system according to claim 19, wherein said endoscopic treating instrument is a high frequency snare.
wherein said flexible tube is adapted to be arranged outside the endoscope when said hood is attached at the distal end of the endoscope, said cap part and said fixing part are substantially cylindrical to be fitted on the distal end of said endoscope which is also substantially cylindrical, wherein the outer diameter of said cap part is greater than the outer diameter of said fixing part, and the center of said cap part is eccentric to that of said fixing part.
23. A hood for an endoscope comprising:
a flexible tube having a distal end which is fixed to said cap part and communicating with the cavity of said cap part through the opening, and a proximal end through which an endoscopic treating instrument can be removably inserted into the flexible tube without connecting a tube arranged inside the endoscope thereto; and
a flange-shaped connecting portion which connects a proximal end of said cap part and a distal end of said fixing part;
wherein said flexible tube is adapted to be arranged outside the endoscope when said hood is attached at the distal end of the endoscope, said cap part and said fixing part are substantially cylindrical to be fitted on the distal end of said endoscope which is also substantially cylindrical, wherein the outer diameter of said cap part is greater than the outer diameter of said fixing part, and said connecting portion is tapered.
24. A hood for an endoscope comprising:
wherein said flexible tube is adapted to be arranged outside the endoscope when said hood is attached at the distal end of the endoscope, said cap part and said fixing part are substantially cylindrical to be fitted on the distal end of said endoscope which is also substantially cylindrical, wherein the outer diameter of said cap part is greater than the outer diameter of said fixing part, and the distal end of said flexible tube is connected to said connecting portion.
