うになつている。 Generally, an endoscope has a bending operation mechanism built into its operation section, and by operating this bending operation mechanism, the operation section and the insertion section are pushed and pulled, thereby making it possible to remotely bend the insertion section. It's getting old. By the way, inside the main body of the operation section,
Tether rings are provided at the top and bottom. The operating wire is inserted through the connecting ring and guided by a wire guide made of a tightly wound coil. The end of the wire guide on the operating section side is supported by a substantially disc-shaped support member attached to the lower connecting ring. The support member has a groove with a V-shaped cross section carved into the entire circumferential surface of the support member, and the support member is attached and fixed by pushing the tip of a screw screwed from the lower connecting ring into the V groove. There is.

It had drawbacks such as going crazy. Additionally, if the position where the screw is fixed deviates from the opposing position on the central axis of the support member, the screwing force of the screw will work in the direction of detaching the support member from the lower connecting ring, weakening the strength for fixing the support member. There was a drawback.

イヤガイド支持部材６１を固定する強度は強い。 On the other hand, as shown in FIGS. 2, 6, and 7, the second connecting ring 12 is made of a material that can be deformed at the tip of the set screw, such as relatively soft material such as aluminum or plastic, as will be described later. A disk-shaped wire guide support member 61 formed of
is installed. That is, the second connecting ring 12 has a stepped portion 62 at the inner end, with the inner diameter of the protruding pieces 25, 25 being larger than the other parts.
A fitting hole 63 is formed, and the inner diameter of the fitting hole 63 is set so that the wire guide support member 61 is tightly fitted therein. And the fitting hole 6
3, the wire guide support member 61 is deeply fitted and positioned until it touches the stepped portion 62. Further, a tapered slope 64 is formed on the peripheral edge of the wire guide support member 61 on the opposite side from the stepped portion 62 over the entire circumference thereof. The projecting pieces 25, 2 are positioned so as to correspond to the slope 64 of the wire guide support member 61 in the fitted state on the central axis of the wire guide support member 61.
Screw holes 65 and 66 are formed in each of the screw holes 65 and 66, and setscrews 67 and 68 are screwed into the screw holes 65 and 66, respectively. Further, the tips 67a, 68a of each of the setscrews 67, 68 are tapered in a conical shape, and the inclination angle thereof is matched to the angle of the slope 64, for example. However,
After fitting the wire guide support member 61 into the fitting hole 63, the setscrews 67 and 68 are screwed in as shown in FIG.
The inclined side surface portion of 8a hits the slope 64, pushes the wire guide support member 61 toward the step 62, presses it against the step 62, tightens it, and bites into the slope 64 to be fixed. Moreover, since the inclined side surfaces of the tips 67a and 68a of the setscrews 67 and 68 deform the slope 64 and bite into it, the wire guide support member 61 is fixed in a fixed position so that it cannot rotate in the circumferential direction. be done. Furthermore, since the two set screws 67 and 68 are fixed at opposing positions on the central axis of the wire guide support member 61, the screwing force of the set screws 67 and 68 is applied to the central axis of the wire guide support member 61. Due to the balance, the wire guide support member 61 does not move away from the second connecting ring 12. Therefore, the strength for fixing the wire guide support member 61 is strong.

い。 As explained above, the present invention provides a fitting part in which the wire guide support member is positioned and fitted in the connecting ring at the lower part of the operation part, and the wire guide support member is fitted into the fitting part and positioned. Then press the side surface of the pointed tip of the set screw, which is engaged at a position opposite to the central axis of the wire guide support member of the lower connecting ring, against the edge of the wire guide support member, and The set screw is fixed by pressing it against the screw, and the sharp tip of the set screw is inserted into the edge of the screw. Therefore, there is no need to carve a V-shaped groove in the wire guide support member as in the conventional wire guide support member, and the processing thereof is easy. Furthermore, since the side surface of the sharp tip of the set screw is fitted into the edge of the wire guide support member, the wire guide support member is securely fixed and does not rotate. Further, since the set screws are engaged at opposing positions on the central axis of the wire guide support member, the screwing force of the set screws does not act in a direction that would cause the wire guide support member to come off the lower connecting ring. Therefore, the strength for fixing the wire guide support member is strong.
