A surgical treatment apparatus according to the present invention includes an outer sheath, extending from a base portion subject to an operator's hand to the tip subject to insertion into a body cavity, that is provided with a working channel through which a treatment instrument can be passed; an image pickup device disposed at the tip portion of the outer sheath; and pivotable forceps disposed at the tip portion of the outer sheath, supported on a supporting section protruding in the axial direction via a joint being bent away from the working channel, and having a pair of forceps members arranged so as to be freely opened/closed, wherein the image pickup device is disposed at a position between the axis line of the supporting section and the axis line of the working channel and offset from an imaginary line connecting the two axis lines.

Surgical treatment apparatus

An instrument for an endoscope includes a first insertion portion having an base end to which an operation section is connected; a first offset portion extending outward from an axis of the first insertion portion; a second insertion portion having a base end joined to the first offset portion and an element extending parallel to the axis of the first insertion portion; a second offset portion which is joined to a head of the second insertion portion and reaches an extension of the axis of the first insertion portion; a third insertion portion which is joined to the second offset portion and has a portion arranged on an axis which is substantially the same as at least a part of the axis of the first insertion portion; and an inner hole formed through the first insertion portion, the first offset portion, the second insertion portion, the second offset portion, and the third insertion portion.

Instrument for endoscope having pivotable offset portions

A treatment system includes a guide component that is used to insert a treatment tool into a body cavity, a tilt sensor that is provided in the guide component and detects an angle of inclination of the treatment tool that has been inserted inside the guide component, an insertion amount sensor that is provided in the guide component and detects an amount that the treatment tool has been inserted inside the guide component, a switching device that switches an observation range of images of an interior of the body cavity that are acquired by an observation device that has been introduced into the body cavity and are then displayed on a display unit, and a system control unit that drives the switching device based on information about the angle of inclination and insertion amount of the treatment tool.

Treatment system, trocar, treatment method and calibration method

A tissue cutting device includes an insertion section which is inserted inside a specimen and extends from a distal end to a proximal end, openings which are formed in a distal end side of the insertion section inserted into the specimen, tissue cutting members which pass through the openings, extend such as to protrude in a direction intersecting the axial line of the length direction from the distal end of the insertion section to the proximal end, and are drawn into the insertion section from the same openings after forming a loop which tissue can be inserted into, a control member which is connected to the tissue cutting members, and a controller for controlling the control member; tissue passed through the loops being cut by controlling the control member and drawing the tissue cutting members from the openings into the insertion section.
