BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an instrument used together with an endoscope in a surgical operation using the endoscope. [0003] 2. Description of the Related Art [0004] In a surgical operation using an endoscope, treatment tools such as forceps are used. An example of the treatment tool is disclosed in U.S. Pat. No. 6,245,085. In an operation using such a treatment tool, a hole (called a "port") having a diameter of 5 to 10 mm is provided in a body wall, and the treatment tool is inserted through the hole. In this case, the area where treatment is possible is narrower in comparison with an open operation in which a portion of a body wall is cut and opened. Therefore, when an area to be treated is large or the position of the hole is inappropriate with respect to the part to be treated, the operation of the treatment tool may be difficult, or the treatment may be complicated. In such a case, if another hole is provided at another position, the damaged area in the patient's body is increased in size. [0005] PCT International Publication, No. WO98/48687 discloses a treatment tool for solving the above problems. In the disclosed treatment tool, a treatment section and an operation section are not coaxially arranged. When using such a treatment tool, it is difficult for the operator to intuitively know the position to be treated. Additionally, a possible amount of offset between the treatment section and an inserted portion is restricted depending on the outer diameter of the hole provided in a body wall. In order to secure a sufficiently wide area which can be treated, the diameter of the hole must be large. Therefore, it is difficult to perform wide area treatment with low damage. SUMMARY OF THE INVENTION [0006] An instrument for an endoscope according to the present invention includes: [0007] a first insertion portion having an base end portion to which an operation section is connected; [0008] an first offset portion extending outward from an axis of the first insertion portion; [0009] a second insertion portion having a base end portion joined to the first offset portion and an element extending parallel to the axis of the first insertion portion; [0010] a second offset portion which is joined to a head portion of the second insertion portion and reaches an extension of the axis of the first insertion portion; [0011] 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 [0012] 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. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 is a diagram showing the structure of a surgical treatment tool as an embodiment of the instrument for the endoscope. [0014] FIG. 2 is a sectional view showing the structure of an operation section. [0015] FIG. 3 is a sectional view showing the structure of a treatment section. [0016] FIG. 4 is a diagram showing a head portion of an insertion section and divisions of a scale provided in the treatment section. [0017] FIG. 5 is a diagram showing a state in which the head side of the insertion section is linearly arranged. [0018] FIG. 6 is a diagram explaining a method of using the surgical treatment tool. [0019] FIG. 7 is a diagram explaining a method of using the surgical treatment tool. [0020] FIG. 8 is a diagram explaining a method of using a conventional surgical treatment tool. [0021] FIG. 9 is a diagram showing a variation of the insertion section. Continue reading...
