摘要:
In an endoscope therapeutic device having a plurality of introduction guide tubes for introducing a treatment tool into a body cavity, the introduction guide tubes are mutually joined at a position more proximal than bending portions thereof. Accordingly, the effects caused by the movement of the plurality of the introduction guide tubes are mutually invalidated at a joint portion as a fulcrum, so that the position of the introduction guide tube is relatively stabilized in the body cavity. As joining methods, there are integration, usage of a joint tool, and usage of an over tube. The operability is improved when the introduction guide tube is provided at the distal end thereof with a mechanism for retaining and/or rotating a distal end of a treatment tool inserted therethrough.

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.

When a living tissue of a ligation target is ligated by means of a snare wire, the snare wire is brought into contact with the living tissue of a ligation target, on a large contact face by means for preventing living tissue cut-in of a ligation target of at least one of a distal end chip and a rear end ring of a loop section of the snare wire, thereby preventing the living tissue of a ligation target from cutting into a contact face of at least one of the distal end chip and rear end ring of the loop section.

The present invention is an endoscope apparatus including an endoscope comprising an observation optical system in which the angle of observable field of view for observing a therapeutic tool can be changed and an operating mechanism for changing the observable field of view; and an insertion guide tube for guiding the therapeutic tool into a body cavity, wherein the insertion guide tube is detachably positioned and supported in a predetermined position relative to the endoscope. With this apparatus, the therapeutic tool can be observed in an optimal observing state irrespective of whether the area to be observed is located near or far from a distal end of the endoscope.

In a medical system including an over-tube for inserting a tool, the medical system includes a restraining mechanism for restraining at least one of a relative movement between the tool to be inserted through the over-tube and the over-tube and a relative movement between the over-tube and the body cavity. The restraining mechanism includes a mechanism for engaging the tool with the distal end of the over-tube, a mechanism for supporting the over-tube outside the body cavity, and a mechanism for connecting the endoscope to the distal end of the over-tube. When engaging the tool with the distal end of the over-tube, a resilient strip or a balloon can be used. When supporting the over-tube outside the body cavity, at least two holders can be used.

An endoscope is provided which has a first forceps raising base and a second forceps raising base. The first forceps raising base is provided at a distal end opening of a first treating tool insertion channel formed at a distal end of an insertion section, and is adapted to be raised in a first direction. The second forceps raising base is provided at a distal end opening of a second treating tool insertion channel formed at the distal end of the insertion section, and is adapted to be raised in a second direction different from the first direction. The first and second raising directions of the first and second forceps raising bases are different from each other in at least two combinations.
摘要:
The present invention is directed to an endoscopic surgery apparatus for performing treating operation in a body cavity of a patient with the use of treating tools in combination with an endoscope, in which insertion sections allowing the insertion of treating tools are externally arranged in a side-by-side fashion with an insertion section of the endoscope set between these insertion sections and a balloon is provided near a distal end of the insertion section of the endoscope to adjust a relative distance between the insertion sections relative to the insertion section of the endoscope. The balloon is provided on the insertion section of the endoscope and, when the endoscope and treating tools are introduced into the body cavity of the patient, it is possible to easily and properly lead the endoscope and treating tools to a region of interest of the patient.
