【0098】ところで、処置具を挿入・抜脱するための挿抜装置の回転駆動ローラー14の外周部分(挟持面) [0098] Incidentally, the outer peripheral portion of the rotating drive roller 14 of the insertion device for inserting and pulling out the treatment tool (sandwiching face)
が平面であると、処置具を挿入・抜脱する際に処置具が回転駆動ローラー14の軸方向にずれて外れてしまう虞がある。 There is a possibility that when a plane, the treatment instrument deviates displaced in the axial direction of the rotary drive roller 14 when inserted and pulled out a treatment tool. こうした問題を解決する手段を以下に示す。 The means for solving these problems is shown below.

【0099】図27の構成では、回転駆動ローラー14 [0099] In the configuration of FIG. 27, the rotational driving roller 14
の外周に凹状の処置具保持用溝部101が設けられている。 Concave treatment instrument holding groove 101 is provided on the outer circumference of. これによれば、案内部材本体25(図4等参照)に挿通された処置具3のシース10が回転駆動ローラー1 According to this, the guide member body 25 the sheath 10 (FIG. 4, etc. see) to be inserted a treatment tool 3 rotates drive roller 1
4に設けられた処置具保持用溝部101に嵌まり込んで挟持される。 It fits to the treatment instrument holding groove 101 provided 4 is nipped. したがって、処置具3が回転駆動ローラー14から外れることがないため、挿入・抜去時の操作性が良い。 Therefore, the treatment instrument 3 to be disengaged from the rotating drive roller 14, a good operability during insertion and removal.

【0100】一方、図28の構成では、装置本体12にピン103を介して略L形状のズレ防止部材102が取り付けられている。 [0100] On the other hand, in the configuration of FIG. 28, the anti-displacement member 102 of a substantially L-shaped it is attached via the pin 103 in the apparatus main body 12. 図28の(c)に示すように、装置本体12に取り付けられるズレ防止部材102の部位には切り欠き部104が形成されている。 As shown in (c) of FIG. 28, the cutout portion 104 is formed at the site of the displacement preventing member 102 attached to the apparatus main body 12. この場合、処置具シース10を回転駆動ローラー14に取り付けた後に、装置本体12のピン103にズレ防止部材102の切り欠き部104を噛み合わせる。 In this case, after attaching the treatment instrument sheath 10 to rotate the drive roller 14, causing the pin 103 of the apparatus body 12 engage the notches 104 of the displacement preventing member 102.

【0101】ズレ防止部材102は、これを装置本体1 [0102] anti-displacement member 102, this apparatus main body 1
2に取り付けた際に回転駆動ローラー14との隙間Cが処置具シース10の半径以下となるように形成されている。 Gap C between the rotating drive roller 14 is formed to be equal to or less than the radius of the treatment instrument sheath 10 when attached to 2. さらに、回転駆動ローラー14は、装置本体12との隙間Dが処置具シース10の半径以下となるように設置されている。 Further, the rotation drive roller 14, the gap D between the apparatus main body 12 is installed such that the following radii of the treatment instrument sheath 10.
