[Basic principle]
An endoscope cleaning set 100 according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a perspective view showing an endoscope cleaning set 100. The endoscope cleaning set 100 includes an endoscope front end surface cleaner 1 (hereinafter referred to as “cleaner 1”) and an endoscope front end surface wiper 31 (hereinafter referred to as “wiper 31”). And have.

  The cleaner 1 cleans the distal end surface of the endoscope (for example, the distal end surface 24 of the endoscope 23a in FIG. 3 described later). The cleaner 1 includes a tube 3 (for example, a cylinder or a square tube) and an injection unit 5. The injection unit 5 is provided at the tip of the tube 3. A hole 7 is formed in the injection unit 5, and the liquid supplied from the tube 3 is injected from the hole 7. A portion 9 where the hole 7 is formed in the injection portion 5 is inclined with respect to the longitudinal direction of the tube 3.

  The wiper 31 includes a handle 33 and a wiping portion 35. The wiping portion 35 is provided at the tip portion of the handle 33. The wiping portion 35 is formed with a contact portion 37 that comes into contact with the distal end surface of the endoscope. The contact portion 37 is inclined with respect to the longitudinal direction of the handle 33.

  According to the present embodiment, since the portion 9 where the hole 7 of the cleaner 1 is formed is inclined with respect to the tube 3, the cleaner 1 can be arranged so that the hole 7 and the distal end surface of the endoscope face each other. . Therefore, the liquid ejected from the hole 7 can be directly sprayed on the distal end surface of the endoscope. As a result, the cleaning effect can be enhanced compared to the case where the liquid cannot be sprayed directly onto the tip surface. Furthermore, the cleaning effect can be further enhanced by wiping off the liquid adhering to the distal end surface of the endoscope with the wiper 31.

[Details of Cleaner 1]
With reference to FIG.1 and FIG.2, the detail of the structure of the cleaner 1 is demonstrated. FIG. 2A is a side view of the cleaner 1. FIG. 2B is a side view showing a state where the syringe barrel 15 is attached to the cleaner 1. In FIG. 2A, a partial cross section of the injection portion 5 is shown.

  The injection part 5 is disk shape, for example. A flow path 8 that connects the hole 7 and the inside (flow path) of the tube 3 is formed inside the injection unit 5. The flow path 8 is formed by a pipe, for example. Alternatively, the inside of the injection unit 5 can be made a cavity and the cavity can be used as the flow path 8.

  The tube 3 is linear, for example. The part 9 in which the hole 7 is formed is, for example, planar. The part 9 forms an angle θ1 of 90 degrees or more and less than 180 degrees with respect to the tube 3. As a result, the hole 7 faces the direction (direction indicated by the arrow A) that forms an angle θ2 of 0 degree or more and less than 90 degrees with respect to the tube 3. In the present embodiment, the angle θ1 and the angle θ2 are constant. That is, the injection unit 5 is fixed to the tube 3.

  The portion 9 preferably forms an angle θ1 of 90 degrees or more and 170 degrees or less with respect to the tube 3. It is preferable that the hole 7 is directed in a direction (direction indicated by the arrow A) that forms an angle θ2 of 0 degrees or more and 80 degrees or less with respect to the tube 3.

  The cleaner 1 can further include a handle 11 and a fitting portion 13. The handle 11 is formed at the proximal end of the tube 3. The handle 11 has, for example, a disk shape. The fitting portion 13 is formed at the proximal end of the tube 3. The distal end portion of the syringe barrel 15 is fitted to the fitting portion 13.

The liquid 17 injected into the tube 3 is further supplied to the injection unit 5. As a result, the liquid 17 is ejected from the hole 7 in the direction of the angle θ2.

  For example, the cleaner 1 is made of metal, synthetic resin, or metal and synthetic resin. The cleaner 1 may be a disposable product.

[Usage example of cleaner 1 in laparoscopic surgery]
With reference to FIG. 3, the usage example in the laparoscopic surgery of the cleaner 1 is demonstrated. FIG. 3 is a diagram for explaining a usage state of the cleaner 1 in laparoscopic surgery. In laparoscopic surgery, for example, an endoscope 23a is used. The distal end surface 24 of the endoscope 23a forms a right angle with respect to the axis of the endoscope 23a. The tip surface 24 includes, for example, the surface of an objective lens (not shown).

  In the body B, a port 19 and a port 21 are arranged at an interval. The port 19 and the port 21 are, for example, cylindrical members. The endoscope 23 a is inserted into the body B through the port 19. Then, laparoscopic surgery is performed on the organ P1 and the organ P2. Along with the operation, the distal end surface 24 of the endoscope 23a is contaminated by body fluid, condensation, and the like.

  An operator or an assistant (hereinafter referred to as “operator”) inserts the cleaner 1 into the body B through the port 21 when the distal end surface 24 is contaminated. Since the part 9 where the hole 7 is formed is inclined and the part 9 can be visually recognized by the endoscope 23a, an operator or the like can easily make the hole 7 face the distal end surface 24. An operator or the like grips the handle 11 and aligns the cleaner 1. In addition, the cleaner 1 is inserted into the body B with the syringe barrel 15 fitted. Alternatively, the syringe barrel 15 may be fitted to the cleaner 1 after the cleaner 1 is inserted into the body B.

  When the arrangement of the cleaner 1 is determined, the operator or the like operates the injection cylinder 15 with the handle 11 as a support to inject the liquid 17 into the tube 3. The liquid 17 is supplied from the pipe 3 to the injection unit 5. And the liquid 17 is inject | emitted from the hole 7 of the injection | emission part 5 toward the front end surface 24 of the endoscope 23a. As a result, the liquid 17 is sprayed directly on the tip surface 24 and the tip surface 24 is cleaned. The surgeon removes the cleaner 1 from the body B after cleaning the distal end surface 24. Then, the surgeon resumes the operation. Or an operator etc. perform the wiping work of the front end surface 24 with the wiper 31 so that it may mention later (refer FIG. 5).

[Details of wiper 31]
Details of the structure of the wiper 31 will be described with reference to FIGS. 1 and 4. FIG. 4 is a side view of the wiper 31. The handle 33 is, for example, linear. The wiping part 35 is disk shape, for example. The contact portion 37 forms an angle θ3 of 90 degrees or more and less than 180 degrees with respect to the tube 3. The contact portion 37 preferably forms an angle θ3 of 90 degrees or more and 170 degrees or less with respect to the tube 3. The contact part 37 is planar, for example.

  For example, the handle 33 and the wiping portion 35 (excluding the contact portion 37) are made of wood, metal, or synthetic resin. The contact part 37 has water absorption. For example, the contact part 37 is formed of cotton (for example, gauze). The wiper 31 may be a disposable product.

[Example of use of wiper 31 in laparoscopic surgery]
With reference to FIG.4 and FIG.5, the usage example in the laparoscopic surgery of the wiper 31 is demonstrated. FIG. 5 is a diagram for explaining a use state of the wiper 31 in laparoscopic surgery. For example, after cleaning the distal end surface 24 of the endoscope 23 a with the cleaner 1 and taking out the cleaner 1 from the body B, the operator or the like inserts the wiper 31 into the body B through the port 21. Since the contact portion 37 is inclined and the contact portion 37 can be visually recognized by the endoscope 23a, the surgeon or the like brings the liquid 17 attached to the distal end surface 24 by bringing the contact portion 37 into contact with the distal end surface 24. Can be easily wiped off. The surgeon removes the wiper 31 from the body B after wiping. Then, the surgeon resumes the operation.

[Usage example of cleaner 1 and wiper 31 in spinal endoscopic surgery]
With reference to FIGS. 6-8, the usage example in the spinal endoscopic surgery of the cleaner 1 and the wiper 31 is demonstrated. FIG. 6 is a diagram illustrating a state of the endoscope 23b before the cleaner 1 and the wiper 31 are used. FIG. 7 is a diagram for explaining a use state of the cleaner 1 in spinal endoscopic surgery. FIG. 8 is a diagram for explaining a use state of the wiper 31 in spinal endoscopic surgery.

  As shown in FIG. 6, in a spinal endoscopic operation, for example, an endoscope 23b is used. The endoscope 23b is a perspective mirror. Accordingly, the distal end surface 24 of the endoscope 23b is inclined with respect to the axis of the endoscope 23b.

  A retractor 25 is disposed on the body B. The tip of the retractor 25 abuts on the organs P3 and P4. The retractor 25 is, for example, a cylindrical member. The endoscope 23 b is inserted into the body B through the retractor 25. Then, spinal endoscopic surgery is performed on the organ P5. Along with the operation, the distal end surface 24 of the endoscope 23b is contaminated by body fluid, bone waste, and dew condensation.

  As shown in FIG. 7, the surgeon or the like inserts the cleaner 1 into the body B via the retractor 25 when the distal end surface 24 is contaminated. As in the case of laparoscopic surgery, an operator or the like can easily make the hole 7 face the distal end surface 24.

  When the arrangement of the cleaner 1 is determined, the operator or the like sprays the liquid 17 directly on the distal end surface 24 from the hole 7 and cleans the distal end surface 24 as in the case of laparoscopic surgery. The surgeon removes the cleaner 1 from the body B after washing.

  Then, as shown in FIG. 8, the surgeon inserts the wiper 31 into the body B via the retractor 25. As in the case of laparoscopic surgery, an operator or the like can easily wipe the liquid 17 adhering to the distal end surface 24 by bringing the contact portion 37 into contact with the distal end surface 24. The surgeon removes the wiper 31 from the body B after wiping. Then, the surgeon resumes the operation.
