  Next, the operation of the endoscope 1 and the endoscope pulling rod 4 will be described. FIG. 4 is an explanatory view of the operation of pulling the rod 50 which is a treatment instrument placed for a certain period in the case of treating lacrimal passage obstruction as an example of using the endoscope 1 and the retractor 4 for endoscope. It is. The rod 50 is a flexible member and is inserted from the nasolacrimal duct 67 into the superior lacrimal canal 62. Furthermore, it is inserted into the nasolacrimal duct 67 again from the upper lacrimal canal 62 through the lower lacrimal canal 64, and both end portions 50 a and 50 b of the rod 50 are placed so as to be sent out to the lower nasal passage 68. Below, the detail of the operation | work which pulls this rod 50 with the pulling rod 4 for endoscopes is demonstrated.

  First, the lens barrel 2 to which the endoscope pulling rod 4 is attached is inserted from the nostril and reaches the entrance of the nasolacrimal duct 67 of the lower nasal passage 68 to which both end portions 50a and 50b of the rod 50 are fed out. Then, one of the both end portions 50a and 50b of the rod 50 is engaged with the collar portion 6 of the endoscope pulling rod 4 protruding from the distal end 2b of the barrel 2 and pulled out of the nostril (not shown). Since a series of operations of inserting into these nostrils and engaging and pulling out the rod 50 is performed while observing with the endoscope 1, it can be easily and reliably performed. In particular, as shown in FIG. 5, the collar portion 6 of the endoscope pulling rod 4 that engages the rod 50 protrudes from the distal end 2 b of the lens barrel 2 and is positioned near the central axis 2 d of the lens barrel 2. Therefore, it is possible to work while observing the collar part 6 near the center of the visual field that can be confirmed with the endoscope 1. For this reason, the visibility is further enhanced, and skill of the work is not required, and an easy and reliable pulling work of the rod 50 is realized.

  By the way, the outer diameter of the lens barrel 2 of the endoscope 1 is preferably 4 mm or less in consideration of the size of the nostril and the burden on the patient. The length of the eaves member 5 is not preferably too long, and is preferably about 5 mm. As shown in FIG. 4, the line connecting the nostril and the lower concha 69 is displaced outward with respect to the face center line. For this reason, if the heel member 5 inserted into the nostril is too long, the distal end portion 5a of the heel member 5 faces the outside of the lower nasal passage 68 and abuts against the inner wall of the lower nasal passage 68, making insertion difficult. Because it will end up. Further, the width and length of the flange of the flange portion 6 of the flange member 5 are preferably about 2 mm in practice.

  As shown in FIG. 6, the endoscope pulling rod 4 fixed to the lens barrel 2 is only fixed by friction between the inner peripheral surface of the proximal end portion 8 a of the engaging member 8 and the lens barrel 2. Therefore, by providing a predetermined external force to the engaging member 8, the collar portion 6 can be advanced and retracted in the direction of the central axis 2 d of the lens barrel 2. For this reason, when inserting the lens barrel 2 having the endoscope pulling rod 4 attached in the nostril, not only the entire endoscope 1 is inserted, but also only the endoscope pulling rod 4 is moved forward and backward. It is possible to perform 50 towing operations. It is also possible to adjust the orientation of the collar portion 6 by rotating the endoscope pulling rod 4 in the circumferential direction of the lens barrel 2. Here, as shown in FIG. 7, when only the endoscope pulling rod 4 is advanced and retracted, the distal end 2 b of the barrel 2 does not move relatively, so the field of view is reduced, and the distal end portion 7 a of the fixing member 7 is reduced. And the collar part 6 is confirmed by shrinking. For such a phenomenon, when the diameter of the lens barrel 2 is 4 mm, the field of view is reduced after the forward movement of 3 mm, and only the collar portion 6 is visible at the center of the visual field when the forward movement is about 17 mm. In addition, when the diameter of the lens barrel 2 is 2.7 mm, the visual field is reduced when the forward movement is 2 mm, and only the collar portion 6 is visible at the center of the visual field when the forward movement is about 6 mm. Incidentally, as shown in FIG. 6, the scales 9 may be provided at predetermined intervals in the direction of the central axis 2 d of the outer peripheral surface of the lens barrel 2. By doing in this way, when the endoscope pulling rod 4 is advanced and retracted as described above, the advance / retreat amount can be easily confirmed.

  FIG. 8 shows an endoscope pulling rod 10 according to a first modification of this embodiment. In the endoscope pulling rod 10, the fixing member 11 and the lens barrel 2 are fixed by a substantially cylindrical engaging member 12. The engaging member 12 is made of an elastically deformable material, for example, natural rubber. For this reason, the lens barrel 2 and the fixing member 11 externally fitted to the lens barrel 2 are externally fitted to the engaging member 12 and are fastened and fixed by the elastic force of the engaging member 12. At this time, since the outer diameter of the fixing member 11 is larger than the outer diameter of the lens barrel 2, the force with which the engaging member 12 tightens the fixing member 11 is larger than the force with which the lens barrel 2 is tightened. Therefore, when a predetermined external force is applied in a state where the fixing member 11 is fixed to the lens barrel 2 by the engaging member 12, the fixing member 11 is engaged with the engaging member 12 and the center of the lens barrel 2 is engaged. It is possible to adjust the position and orientation of the collar 6 by moving back and forth in the direction of the axis 2d or rotating in the circumferential direction of the lens barrel 2.

  FIG. 9 shows an endoscope traction rod 13 according to a second modification of this embodiment. In the endoscope pulling rod 13, notches 15 are provided in a part of the fixing member 14, and scales 16 are provided at predetermined intervals in the central axis direction. Therefore, in the endoscope pulling rod 13, when the fixing member 14 is advanced and retracted while being fitted on the lens barrel 2, the tip 2b of the lens barrel 2 is exposed from the notch 15 and can be visually observed. In addition, the position can be quantitatively confirmed by the scale 16.

  FIG. 10 shows an endoscope traction rod 17 according to a third modification of this embodiment. In the endoscope pulling rod 17, the end surface 18b of the distal end portion 18a of the fixing member 18 is inclined with respect to the central axis 18c. Therefore, even in an endoscope in which the end surface 19a of the lens barrel 19 is inclined and can be viewed forward, the fixing member 18 can be fixed to the lens barrel 19 without disturbing the field of view of the endoscope. Note that the inclination angle of the end surface 19a of the lens barrel 19 is 30 degrees or 70 degrees, and the inclination angle of the end surface 18b of the fixing member 18 is also formed accordingly.

  FIG. 11 shows an endoscope pull rod 20 according to a fourth modified example of this embodiment. Like the fixing member 21 of the endoscope pulling rod 20, a notch 22 may be formed and the end surface 21a may be inclined with respect to the central axis 21b.
