It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0026] Please refer to Figures 1 to 9 As shown, an anal dilator includes a sleeve 10. The sleeve 10 is transparent and has a certain rigidity. The sleeve 10 is used to be inserted into the anus and expand the anus. The hollow portion inside the sleeve 10 is used for inspection or insertion of other surgical instruments.

[0027] The sleeve 10 is connected to a handle 20, which includes a first section 21 and a second section 22 that are separately arranged. The first section 21 is fixedly connected to the sleeve 10, and a rotating shaft 23 is provided at the other end of the first section 21. The rotating shaft 23 is rotatably connected to the second section 22. A sheet 30 is provided on the second section 22. The sheet 30 is arranged parallel to the second section 22. The sheet 30 is located outside the second section 22. The second section 22 can rotate relative to the first section 21 through the rotating shaft 23. During the rotation process, the second section 22 can approach or move away from the sleeve 10. When the second section 22 rotates toward the sleeve 10, it is folded with the sleeve 10. Under normal circumstances, the second section 22 can be rotated to the sleeve 10. 0 center line position, such a setting can reduce the packaging volume of the anal dilator, the second section 22 rotates away from the sleeve 10, and when the second section 22 is rotated to be on the same straight line with the first section 21, the part of the sheet 30 outside the second section 22 is in contact with the first section 21. At this time, the doctor can insert the sleeve 10 into the anus, and it is also convenient for the doctor to apply force on the handle 20 to drive the sleeve 10 out of the patient's body. After the sleeve 10 is completely out of the patient's body, continue to rotate the second section 22 to move it away from the sleeve 10, and the sheet 30 is broken, thereby playing a marking role, ensuring that the anal dilator can only be used once, avoiding cross infection, and being safer and more reliable.

[0028] When the first section 21 and the second section 22 are in the same straight line, in order to better fix the first section 21 and the second section 22 and facilitate the doctor to better apply force on the handle 20, a through hole 31 is provided at one end of the sheet 30 located outside the second section 22, and the first section 21 is provided with a protrusion 24, which is circular and fits into the through hole 31.

[0029] In order to prevent the handle 20 from hitting the human body after the sleeve 10 is inserted into the anus, the counterclockwise angle α between the first section 22 and the center line of the sleeve 10 is greater than 90°.

[0030] In one embodiment, please refer to Figures 3 to 9 As shown, the sleeve 10 includes a cylindrical body 11 and a conical body 12 that are coaxially connected. The cylindrical body 11 includes a first end 111 and a second end 112. The radius of the cylindrical body 11 gradually increases from the first end 111 to the second end 112. The cylindrical body 11 is inserted into and stretches the anus, so that the anus gradually adapts to the size of the sleeve 10 and reduces the patient's pain. The second end 112 is connected to the conical body 12. The radius of the conical body 12 gradually increases from close to the second end 112 to away from the second end 112, so that the conical body 12 remains outside the body. The setting of the conical body 12 is conducive to applying force to the conical body 12 to insert the cylindrical body 11 into the anus. The conical body 12 is connected to the first section 21.

[0031] In this embodiment, the cylindrical body 11 , the conical body 12 , the first section 21 and the rotating shaft 23 are integrally formed.

[0032] In one embodiment, please refer to Figures 6-9 As shown, a guide member 40 is also movably provided in the sleeve 10. One end of the guide member 40 is provided with a seat body, and a conical pre-supporting surface 41 is formed on the outer periphery of the seat body. The conical portion of the pre-supporting surface 41 is an arc surface. A force block 42 is provided on the other end of the guide member 40. In this embodiment, the force block 42 is circular. The guide member 40 can be inserted into and passed through the cylindrical body 11. At this time, the pre-supporting surface 41 partially passes through the first end 111, and the pre-supporting surface 41 and the outer periphery of the first end 111 are smoothly transitioned. The pre-supporting surface 41 can partially pass through the first end 111, which means that the outer diameter of the portion of the pre-supporting surface 41 passing through the first end 111 is smaller than the outer diameter of the first end 111, and the conical portion is outside the first end 111. The pre-supporting surface 41 is inserted into the anus first, which can reduce the patient's pain.

[0033] Please refer to Figure 9 As shown, in this embodiment, after the guide member 40 is inserted into the cylindrical body 11, the force block 42 is located in the conical body 12, which can further reduce the packaging volume.

[0034] In this embodiment, a limit block 43 is further provided on the guide member 40. The limit block 43 is arranged between the force block 42 and the pre-support surface 41. When the guide member 40 is inserted into the sleeve 10, the radius of the limit block 43 is greater than the radius of the second end 112, and the movement of the guide member 40 is limited by the limit block 43.

[0035] During use, first insert the guide member 40 into the sleeve 10 and make the pre-support surface 41 partially pass through the first end 111, turn the second section 22 to the same straight line as the first section 21, and then apply force to the force block 42 to insert the pre-support surface 41 and the cylindrical body 11 into the patient's anus in sequence and gradually. After the cylindrical body 11 is inserted to a certain depth, the guide member 40 is pulled out of the sleeve 10 by the force block 42, and then the hollow part of the sleeve 10 can be directly inspected or other surgical instruments can be inserted for inspection or surgery. After the inspection or surgery is completed, the sleeve 10 is gradually driven out of the anus by the handle 20 until it is completely out of the anus, and then the second section 22 is continued to be rotated away from the sleeve 10, and the sheet 30 is broken to ensure that the anal dilator is only used once.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
