Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] The orientations mentioned in this specification refer to the orientation of the anoscope of this utility model when it is working normally. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0026] Example 1

[0027] like Figures 1 to 6 As shown, the anoscope includes a cover 1 and a push rod 2. The front end of the cover 1 is provided with an opening 100 and the rear end of the cover 1 is provided with a handle 110. The front end of the push rod 2 is provided with an arc-shaped head 20, which is used to block the opening 100 during use.

[0028] In this embodiment, the cover 1 is a telescopic cylinder, making its length adjustable. Specifically, the cover 1 includes a first cylinder 10 and a second cylinder 11. An opening 100 is provided in the first cylinder 10, and a handle 110 is provided in the second cylinder 11. The front end of the second cylinder 11 is fitted inside the first cylinder 10, and the first cylinder 10 and the second cylinder 11 can slide relative to each other. The inner wall of the first cylinder 10 is provided with a plurality of V-shaped grooves 101 arranged at intervals along the length direction. The outer wall of the second cylinder 11 is provided with an elastic block 111. The elastic block 111 includes an elastic plastic strip, one end of which is fixed to the second cylinder 11, and the other end is fixed to the V-shaped block. The axial direction of the telescopic cylinder, the arrangement direction of the V-shaped grooves 101, and the...

[0029] The elastic locking block 111 is engaged in the V-shaped locking groove 101, and as the telescopic cylinder extends and retracts, it switches between different V-shaped locking grooves 101 to achieve locking after the telescopic cylinder is extended and retracted.

[0030] Furthermore, a first retaining ring 12 is fitted inside the first cylinder 10 with a gap. A first connecting block 102 is fixed between the outer wall of the first retaining ring 12 and the inner wall of the first cylinder 10. A track groove 112 is provided on the side wall of the second cylinder 11. The first connecting block 102 is located in the track groove 112 and slides synchronously in the track groove 112 as the first cylinder 10 and the second cylinder 11 slide relative to each other.

[0031] The second retaining ring 21 is coaxially fixed on the push rod 2. The second retaining ring 21 has an outward protrusion 210. The first retaining ring 12 has an L-shaped groove 120. The outward protrusion 210 is engaged in the L-shaped groove 120.

[0032] In use, insert the push rod 2 into the telescopic cylinder and engage the first retaining ring 12 with the second retaining ring 21. Specifically, first, insert the protruding part 210 into the longitudinal groove of the L-shaped groove, and then rotate it so that the protruding part 210 is engaged into the transverse groove of the L-shaped groove, thus fixing the push rod 2 and the first cylinder 10 relatively. Then, hold the handle 110 and push or pull the push rod 2 to achieve the initial telescopic adjustment of the telescopic cylinder.

[0033] During operation, insert the anoscope into the anus, and then slowly push and pull the push rod 2 as needed to achieve secondary extension and retraction adjustment of the telescopic cylinder. After adjustment, first rotate the push rod 2, and then pull the push rod 2 out. At the same time, the outer protrusion 210 enters the longitudinal groove from the transverse groove of the L-shaped groove, so that the first retaining ring 12 and the second retaining ring 21 separate, thus completing the disassembly of the push rod 2.

[0034] Finally, a medical examination will be conducted.

[0035] This structure enables automatic adjustment of the anoscope, making it suitable for patients with different anal depths, resulting in more accurate examinations and greater ease of use.

[0036] Furthermore, a rubber pad 200 is provided on the part of the arc surface of the arc head 20 that contacts the inner side of the opening 100. The rubber pad 200 is elastically supported between the arc head 20 and the opening 100, thereby driving the outer protrusion 210 to press tightly against the transverse groove inner wall of the L-shaped groove, thereby improving the firmness of the connection between the push rod 2 and the first cylinder 10.

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is that, Figure 7 As shown, a guide rod 103 is fixed on the first connecting block 102, and the guide rod 103 is slidably connected in the track groove 112; the second cylinder 11 is provided with a storage groove 113, which is connected to the track groove 112. One end of the guide rod 103 is located in the storage groove 113 and covers the entire track groove 112 to prevent anal secretions from entering the cover 1 through the track groove 112 and affecting its use.

[0039] Example 3

[0040] The difference between this embodiment and Embodiment 1 is that, Figure 8 As shown, the push rod 2 has an external scale, and the handle 110 has an indicator needle 117 for indicating the scale. By indicating the corresponding scale through the indicator needle 117, the telescopic length of the telescopic cylinder can be precisely adjusted.

[0041] In this embodiment, the handle 110 is disposed on the outside of the slide groove 114, which extends radially along the second cylinder 11. The slider 116 is slidably connected inside the slide groove 114. A second spring 24 is provided inside the slide groove 114 to drive the slider to slide away from the second cylinder 11. An indicator needle 117 is fixedly connected to the outside of the slider 116. By pushing the slider 116, the indicator needle 117 is extended or retracted. By pushing the slider 116, the indicating end of the indicator needle 117 is brought close to the scale line to achieve the indicating function. After the indication is completed, the slider 116 can be reset without affecting subsequent inspection and use.

[0042] Example 4

[0043] The difference between this embodiment and Embodiment 1 is that, Figure 9 As shown, the push rod 2 has a sliding cavity 22, and a slide rod 23 is provided in the sliding cavity 22. The outer end of the slide rod 23 extends to the outside of the push rod 2. A second spring 24 is provided in the push rod 2 to drive the slide rod 23 to slide outward. The outward protrusion 210 has a sliding hole, which is parallel to the axial direction of the slide rod 23. A top post 212 slides in the sliding hole, and a second connecting block 211 is fixed between the top post 212 and the slide rod 23. When assembling the push rod 2 and the first cylinder 10, the outer end of the slide rod 23 is pressed, so that the top post is retracted into the sliding hole. After the outward protrusion 210 is fully inserted into the transverse groove of the L-shaped groove, the slide rod 23 is released, so that the top post moves outward and presses against the inner wall of the transverse groove of the L-shaped groove, thereby improving the firmness of the connection between the push rod 2 and the first cylinder 10.

[0044] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
