  ADVANTAGE OF THE INVENTION According to this invention, the protector which makes it possible to use it for object observation, maintaining the insertion part of an endoscope scope in a clean state is realizable.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating an endoscope scope.

  The endoscope scope 20 is a part of an electronic endoscope apparatus, and has an operation unit 26 having operation buttons such as a suction button 22 and an air supply / water supply button 24, and extends from the operation unit 26 and is a subject. The insertion part 30 inserted in a patient's body is included. The end portion 32 of the insertion portion 30 is provided with a light guide, an objective lens, an air / water supply nozzle, and the like (not shown). The insertion part 30 can be bent because it is inserted into the human body, and in particular, the vicinity of the end part 32 can be bent at a large angle in order to facilitate subject observation and treatment of the affected part. The operation unit 26 is detachably attached to a processor (not shown) via a cable (not shown).

  An operator such as a doctor inserts the insertion section 30 that has been cleaned in advance and has a clean surface into the patient's body gradually from the end 32 prior to subject observation. For this reason, the operator's hand generally contacts the insertion portion 30 whose surface is exposed from the end portion 32 to the operation portion 26 side. As a result, dust or the like may adhere to the surface of the insertion portion 30.

  FIG. 2 is a diagram showing a protector for protecting the insertion portion 30 in the first embodiment. FIG. 3 is a view showing the protector in a state in which the distal end portion is separated.

  The protective device 10 covers the surface of the insertion portion 30 to allow the endoscope scope 20 to be stored and used while keeping the insertion portion 30 in a clean state. The protective device 10 is formed of, for example, a flexible plastic film such as polyethylene, and covers the distal end portion 12 covering the end portion 32 of the insertion portion 30 and the surface of the insertion portion 30 excluding the end portion 32. A cylindrical covering portion 14 is included. Since the covering portion 14 is stretchable, it can be bent together with the insertion portion 30.

  Since the protector 10 is attached to the endoscope scope 20, a contact portion 18 that covers the lower end portion 28 of the operation portion 26 is provided at the end portion of the covering portion 14 opposite to the distal end portion 12. . The contact portion 18 has a cylindrical shape and extends outward from the end portion of the covering portion 14. In FIG. 2, for convenience of explanation, the diameter length L1 of the contact portion 18 and the diameter length L2 of the covering portion 14 are shown to be longer than the actual length (the same applies to the following drawings). The length L1 of the diameter is longer than the diameter of the insertion portion 30 and shorter than the diameter of the lower end portion 28 of the operation portion 26. And when attaching the protector 10 to the operation part 26, the contact part 18 covers the taper-shaped lower end part 28, extending and expanding.

  The distal end portion 12 can be separated from the covering portion 14 with a cut line A provided between the distal end portion 12 and the covering portion 14 as a boundary in order to allow insertion of the insertion portion 30 for observing the subject (see FIG. 3).

  FIG. 4 is a diagram showing the protective device 10 before use in the present embodiment.

  Prior to use, the protective device 10 is stored in a state where the end portion of the covering portion 14 on the distal end portion 12 side and the end portion of the covering portion 14 on the opposite side of the distal end portion 12 are connected by a fixing tape 34. ing. The fixing tape 34 can be easily removed and is removed prior to use of the protective device 10. Thus, since the covering portion 14 can be folded into a bellows shape, the protector 10 has an inner surface of the covering portion 14 (a surface on the insertion portion 30 side when attached to the endoscope scope 20) as a foreign substance. Even when the covering portion 14 is in contact with the insertion portion 30 at the time of use, the insertion portion 30 can be prevented from being soiled.

  FIG. 5 is a diagram illustrating a use state of the protective device 10 according to the present embodiment.

  Prior to subject observation, the operator removes the fixing tape 34, covers the insertion portion 30 with the protective device 10, and separates the distal end portion 12 of the protective device 10 that covers the end portion 32. And the insertion part 30 is operated via the coating | coated part 14, and the insertion part 30 is gradually inserted in a patient's body from the edge part 32. FIG. Since the distal end portion 12 is cut off and the distal end of the protective device 10 is a free end, it does not enter the patient's body as the insertion portion 30 is inserted, and the protective device 10 has a bellows shape in the vicinity of the insertion position. It will be folded. Thus, since the hand of the technician does not directly contact the insertion portion 30, the subject is observed while the insertion portion 30 is maintained in a clean state. Further, when the insertion portion 30 is pulled back from the patient's body after observing the affected area, the insertion portion 30 to which the patient's bodily fluid or the like is attached is housed on the inner surface side of the protective device 10, so that the clothes and the like of the technician may be stained. Absent.
