20090259105 | MEDICAL TREATMENT SYSTEM AND SUTURING METHOD - A medical treatment system including an endoscope, a treatment tool that is inserted in a channel of the endoscope, and a holder that holds the treatment tool in a manner that enables a user who operates the endoscope to move the treatment tool forward and backward and rotate the treatment tool, with the treatment tool having a treatment portion that performs treatment on a living body; a wire for operating the treatment portion whose distal end is connected to the treatment portion; a sheath portion that has a first sheath that is formed with a coil and in which the wire is inserted in a manner capable of moving forward and backward in the axial direction, and a second sheath that is formed with a coil of a plurality of layers and provided on the outside of the first sheath; and an operating portion to which the base end of the wire is connected and enables forward/backward and rotation operation of the wire; and with the holder holding the operating portion so as to be in a predetermined positional relation with respect to the endoscope. | 10-15-2009 |
20100217292 | LIVING TISSUE LIGATION DEVICE - This invention includes a clip having arms which grip living tissue, a press tube serving as a clamping member which is fitted and mounted on the clip to close the arms of the clip, a coupling member which can be inserted into the press tube and engages with the clip, and projections serving as lock portions which hold the arms of the clip in a closed state when the clip engages with the press tube. | 08-26-2010 |
20100217293 | LIVING TISSUE LIGATION DEVICE - This invention includes a clip having arms which grip living tissue, a press tube serving as a clamping member which is fitted and mounted on the clip to close the arms of the clip, a coupling member which can be inserted into the press tube and engages with the clip, and projections serving as lock portions which hold the arms of the clip in a closed state when the clip engages with the press tube. | 08-26-2010 |
20100217294 | LIVING TISSUE LIGATION DEVICE - This invention includes a clip having arms which grip living tissue, a press tube serving as a clamping member which is fitted and mounted on the clip to close the arms of the clip, a coupling member which can be inserted into the press tube and engages with the clip, and projections serving as lock portions which hold the arms of the clip in a closed state when the clip engages with the press tube. | 08-26-2010 |
20110071354 | OVERTUBE AND MEDICAL PROCEDURE VIA NATURAL ORIFICE USING THE SAME - An overtube according to this invention includes: an insertion part, that is inserted into a subject and has a lumen, through which a device insertion part of a device for performing a medical procedure inside a body of the subject is removably inserted, the insertion part being inserted into the subject; and a tissue incising part that is disposed at a distal end side of the insertion part so as to cross the lumen and incises a tissue of the subject. | 03-24-2011 |
20110196390 | LIGATION APPARATUS - The present invention relates to a ligation apparatus that ligatures living tissue by a clip and provides an optimal ligation apparatus for ligaturing living tissue in a body cavity. | 08-11-2011 |
20110301416 | MEDICAL TREATMENT ENDOSCOPE - The medical treatment endoscope according to the present invention includes a sheath having a flexibility; at least one arm member having a bending part that projects out from a front end of the sheath and performs bending actions; an open/close mechanism which directs the arm member from a direction along a central axis of the sheath to a direction deviated from the central axis of the sheath, and from a direction deviated from the central axis of the sheath to a direction along the central axis of the sheath; and a viewing device and an illuminating member that are disposed to the front end side of the sheath. | 12-08-2011 |
20140171833 | ENDOSCOPE TREATMENT SYSTEM - The endoscope treatment system includes an endoscope treatment tool that has an operating section including a distal end and a proximal end, and a sheath that is connected to the distal end of the operating section and is formed with a lumen into which the guide wire is capable of being inserted; a guide wire holder that has a tube member, in which the guide wire is accommodated, and that is circumferentially wound; and a fixing member that couples the operating section to the guide wire holder so that the distal end and the proximal end of the operating section are located outside the circumference of the guide wire holder. | 06-19-2014 |
20150087994 | BIOPSY SYSTEM - In the biopsy system according to one embodiment, the needle tube of the treatment tool has the minor axis of the flattened portion and the bending plane of the bending portion parallel to each other. Accordingly, the needle tube is easily bent in the bending direction of the bending portion, and even in an endoscope that has few bendable directions and is bendable, for example, in only two directions (e.g., up and down), the bending operation of the bending portion is not easily hindered. As a result, even after the treatment tool for endoscopes is inserted into the endoscope, the bending portion can be easily bent with a predetermined bending amount, and a procedure can be easily performed. | 03-26-2015 |
