An endoscopic insertion aid includes a tube member, a pipeline and a plurality of balloons. The tube member allows an insertion section of an endoscope to be inserted therethrough, and guides the longitudinal movement of the insertion section. The pipeline is provided in the tube member, and communicates with a supply/discharge unit to supply a fluid to or discharge the fluid from the distal end of the tube member. The balloons are disposed on the outer periphery of the distal end of the tube member longitudinally along the tube member, communicate with the pipeline, and inflate/deflate in accordance with the supply/discharge of the fluid via the pipeline. The balloon disposed on the distal side of the tube member is inflated to have an outside diameter larger than that of the balloon disposed closer to the proximal side than the balloon disposed on the distal side when the balloons are inflated.

Endoscopic insertion aid, endoscopic system, and method of inserting insertion portion of endoscope into body cavity by use of endoscopic insertion aid

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.

Endoscope therapeutic device

An endoscopic treatment device is used with an endoscope. This treatment device includes a transmission member with a flexible structure having a distal end portion to be inserted into a body and can be operated outside the body, a push rod coupled to the distal end portion, and first and second connecting members rotatably coupled to the push rod. The treatment device further includes first and second arm members rotatably coupled to the distal end portion of the connecting member, a holding member rotatably holding the respective arm at a predetermined interval therebetween, and first and second actuating members integrally formed with the arm members and can open/close when the transmission member actuates the first and second connecting members and the first and second arm members through the push rod. This device also includes a needle mounted on at least one of the first and second actuating members.

Endoscopic suturing system

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.

Endoscopic treatment system

A flexible shaft driven to rotate is inserted through a transparent sheath having pliability. By a fiber inserted through the inside thereof, low-coherence light is guided and is made to exit to a living-body tissue side which is an observation target through a lens and a prism forming an exit and entrance portion at the tip portion. Subsequently, the light reflected on the living-body tissue side is guided in order to produce an image. In that case, a positioning member for keeping the exit and entrance portion and the living-body tissue at a proper distance is formed at the tip portion of the sheath or the tip portion of an endoscope through which an optical probe is inserted and, therefore, a stable tomogram image can be produced.

Light scanning probe apparatus using light of low coherence

Light scanning probe apparatus using light of low coherence including a positioning mechanism

An endoscope including; a fixing member detachably mounted to a distal end portion of an endoscope insertion part for detachably fixing and holding a distal end portion of an indwelling tube or a distal end portion of a guide member for guiding the indwelling tube, both of which are provided along the axial direction of the insertion part, to the distal end portion of the insertion part.

Endoscopic system and method for positioning an indwelling tube

An endoscope device is provided which includes a manipulation portion and an inserted portion connected thereto, and an endoscope holder is provided at an elevated position, for example, on a ceiling. The endoscope device is rotatably suspended from the endoscope holder with its inserted portion extending downward. The endoscope holder has an endoscope manipulation unit for operating the endoscope device and peripheral equipment.

Endoscope holder and endoscope device

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.

Endoscope

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.

Endoscopic surgery apparatus

An endoscope apparatus comprises an elongate insert section including an observation window in the distal end portion and inserted into an object to be observed; an observation device for producing an endoscope image, the observation device including a focusing optical system which receives an incident light from the object through the observation window to focus the endoscope image; and a vibration device for vibrating at least a part of the insert section in a direction crossing the axial direction of the insert section, the vibration device including a vibration unit capable of vibrating in itself to vibrate at least the part of the insert section even under a condition that the insert section is not contact with the object.
