[0002] For some patients with rectal anastomotic leakage and anorectal abscess, anal drainage is a more common treatment method. This method mainly involves inserting a drainage tube into the anus to achieve the drainage effect.

[0003] Since anal drainage takes a long time, in order to fix the drainage tube, sutures are often used in clinical practice. That is, the drainage tube is directly sutured to the skin of the surrounding anal area to complete the fixation. However, the above method will cause great pain to the patient, especially when the patient moves, which will cause further pulling of the suture area and cause severe pain. Therefore, it needs to be improved. Utility Model Content

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0026] Figure 1-3 This is the first embodiment of the utility model, an adjustable fixed anal canal, comprising: an anal canal 1, a support ring 21 movably provided on the anal canal 1, the support ring 21 moves along the length direction of the anal canal 1, the support ring 21 can maintain support during traction, thereby avoiding affecting the drainage of the anal canal 1, and at the same time can adjust the position of the support ring 21 according to the specific length and drainage position of the drainage tube for adaptation. Specifically, the connection between the support ring 21 and the anal canal 1 adopts an interference fit. Since the anal canal 1 itself is made of soft material, the support ring 21 can be sleeved on the outside of the anal canal 1.

[0027] Furthermore, in order to facilitate the connection and fixation of the traction rope 4 , a mounting groove 22 for connecting the traction rope 4 is provided on the support ring 21 .

[0028] It also includes traction units 2, which are 2 in number and symmetrically arranged on the human body. Specifically, the symmetrical arrangement is arranged on the front and back sides of the human body. The two traction units 2 can achieve uniform distribution of traction force, thereby further reducing the discomfort caused by traction of the anal canal 1 to improve comfort.

[0029] Specifically, the traction unit 2 includes a fixed seat 3 and a traction rope 4. The fixed seat 3 is used to be connected and fixed to the human body. In the present embodiment, an adhesive ring 16 is provided at the bottom of the fixed seat 3 and is adhered to the human body through the adhesive ring 16. The adhesive ring 16 enables quick and convenient connection. A winding wheel 5 is rotatably provided inside the fixed seat 3. An opening is formed on one side of the fixed seat 3. One end of the traction rope 4 is connected to the anal canal 1, and the other end passes through the opening and is wound around the winding wheel 5. When in use, the winding and releasing of the traction rope 4 is completed by rotating the winding wheel 5.

[0030] Furthermore, since the anal canal 1 will be pulled when the human body moves, in order to avoid the traction rope 4 on the take-up wheel 5 from being released due to the traction, a limiting structure is provided in the fixed seat 3. The limiting structure is connected to the take-up wheel 5 and is used to limit the rotation of the take-up wheel 5 to release the line, thereby achieving a locking effect to ensure the traction effect.

[0031] Furthermore, a limiting ring 6 is provided in the fixed seat 3, and an adjusting cavity 7 and a fixing cavity 8 are formed corresponding to the upper and lower sides of the limiting ring 6. A coaxially arranged connecting rod 9 is provided on the upper side of the winding wheel 5. The connecting rod 9 passes through the winding wheel 5 and is rotatably connected to the bottom of the fixing cavity 8. The winding wheel 5 is maintained in a fixed position in the fixing cavity 8 by the connecting rod 9.

[0032] Furthermore, the limiting structure is a knob 10, and the knob 10 is provided with a connecting hole 18 corresponding to the connecting rod 9 and is connected to the connecting rod 9. At the same time, a gap is formed between the bottom of the connecting hole 18 and the connecting rod 9, and the gap is used for the connecting rod 9 to move relative to the connecting hole 18. A slide groove 12 and a slider 11 are respectively provided between the connecting rod 9 and the connecting hole 18. The slider 11 and the slide groove 12 slide with each other to limit the rotation of the connecting rod 9 relative to the connecting hole 18, so as to realize the movement limit of the connecting rod 9 and the connecting hole 18. The upper end surface of the knob 10 and the inner wall of the adjusting cavity 7 are provided with mutually matching toothed rings 13. A spring 14 is provided between the knob 10 and the limiting ring 6. The spring 14 is used to drive the knob 10 to move upward so that the two toothed rings 13 engage with each other to limit the rotation of the knob 10.

[0033] In the initial state, the two toothed rings 13 are engaged with each other under the drive of the spring 14. At this time, the knob 10 cannot be rotated. When the line is to be reeled in or out, the two toothed rings 13 are separated from each other by pressing the knob 10. At this time, the knob 10 is still connected to the connecting rod 9 through the connecting hole 18, so that the winding wheel 5 can be driven by rotating the knob 10 forward and reverse to realize the line reeling and unwinding action.

[0034] Furthermore, in order to ensure the locking effect, the toothed ring 13 includes a plurality of ratchet teeth 20 arranged in a ring shape. The arrangement of the ratchet teeth 20 can ensure that the two toothed rings 13 will not move back due to the pulling force after being meshed with each other, so as to maintain locking.

[0035] Furthermore, in order to facilitate the use of the knob 10 , one end of the knob 10 away from the reel 5 extends outward to form a column 15 .

[0036] Figure 4 This is the second embodiment of the utility model. It is different from the first embodiment in that it also includes a connecting belt 17. A connecting hole 18 is formed at the bottom of the fixing seat 3. The connecting belt 17 passes through the connecting holes 18 to connect to the fixing seat 3. The connecting belt 17 forms an annular structure for fixing the human body. The size of the annular structure is adjustable. The fixing method using the connecting belt 17 can adapt to the use requirements when wearing for a long time, so as to avoid the defect of easily causing pressure sores due to the adhesion method.

[0037] Furthermore, the connection belt 17 is provided with a Velcro 19 and is connected to each other through the Velcro 19 to form a ring structure. In another embodiment, buttons can also be used for connection and fixation.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
