Technical Field

[0001] This utility model relates to the field of anal fistula drainage tubes, and in particular to a retractable anal fistula drainage tube. Background Technology

[0002] Anal fistula is a common and complex disease in the field of anorectal diseases. Its occurrence causes a lot of pain to patients and seriously affects their quality of life. Anal fistula is usually a chronic infected tract formed after the rupture or incision of a perianal abscess. The internal opening is mostly located near the dentate line, and the external opening is located on the perianal skin. Its typical characteristics are that it is slow to heal or intermittently recurs.

[0003] In the treatment of anal fistula, drainage is one of the key aspects. Effective drainage can promptly remove pus and exudate from the fistula lesion, prevent further spread of infection, and create favorable conditions for wound healing.

[0004] Traditional drainage tubes are mostly of fixed length. However, there are significant differences in the condition of anal fistulas among different patients, including the depth, location, and direction of the fistula. Fixed-length drainage tubes cannot accurately adapt to these individual differences. The drainage tube may be too short to reach the lesion for effective drainage, or too long to cause unnecessary pressure and irritation to the surrounding normal tissue, thus affecting the treatment effect. Therefore, a telescopic anal fistula drainage tube is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a retractable anal fistula drainage tube, which aims to improve the problem in the prior art that "fixed-length drainage tubes cannot accurately adapt to these individual differences, affecting the treatment effect".

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a retractable anal fistula drainage tube, comprising a tube body 1 capable of accommodating an extension tube 2. The extension tube 2 is slidably connected to the inner wall of the front part of the tube body 1, and the length of the extension tube 2 can be adjusted according to actual usage needs to adapt to different patient treatments. A drainage hole 4 is provided through the outer side of the tube body 1, with multiple sets to ensure that exudate from the anal fistula site can flow smoothly into the tube and then be discharged from the body to achieve the purpose of drainage. An extension mechanism is provided on the inner wall of the tube body 1, which includes a limiting component and a supporting component. The limiting component includes a fixing member 31, which is made of a rigid material and can provide shape support for the tube body 1. Two sets of fixing members 31 are provided, and the two sets of fixing members 31 are respectively located on the left and right sides of the limiting bead 32 to limit the deformation of the tube body 1 by the limiting bead 32.

[0033] Furthermore, the fastener 31 is fixedly connected to the inner wall of the tube body 1, and the inner wall of the tube body 1 is fixedly connected to the limiting bead 32. Under the action of the elastic force of the tube body 1, it can be locked into the limiting groove 34, thereby fixing the extension tube 2, ensuring the relative stability of the tube body 1 and the extension tube 2, preventing the extension tube 2 from accidentally sliding when the length does not need to be adjusted, and maintaining the smooth progress of the drainage process. Multiple sets of limiting beads 32 are provided, and the multiple sets of limiting beads 32 are evenly arranged with the central axis of the tube body 1 as the center. The extension tube 2 has a limiting groove 34 on the outside, and multiple sets of support members 35 are provided. The limiting beads 32 are locked into the inner side of the limiting groove 34. The inner wall of the extension tube 2 near the limiting groove 34 is fixedly connected to the support member 35. The support member 35 is made of rigid material and is used to support the extension tube 2 and the limiting groove 34 to prevent the extension tube 2 from deforming when it is fixed.

[0034] Reference Figure 2 and Figure 3 The support component includes a sleeve 36, which is fixedly connected to the inside of the tube body 1 to seal the inside of the extension tube 2, thus improving the applicability of the device. The outside of the sleeve 36 slides on the inner wall of the extension tube 2. An auxiliary component 33 is fixedly connected to the inner wall of the sleeve 36. It is made of rigid material and can support the extension tube 2, thereby further preventing deformation of the extension tube 2 and preventing leakage. The tube body 1 and the extension tube 2 are made of flexible material, which has better plasticity and is convenient for medical staff to operate. The device shape can be quickly and accurately adjusted according to the actual situation of the patient, thus improving the applicability and ease of use of the device.

[0035] Reference Figure 1 , Figure 4 and Figure 5 A connecting assembly is provided on the outer side of the tube body 1. The connecting assembly includes a first connector 51, which is rotatably connected to the inner wall of the outer side of the tube body 1. A hook 52 is fixedly connected to the front side of the first connector 51. When fixing the device, the direction of the hook 52 can be flexibly adjusted by rotating the first connector 51 to adapt to the fixation needs of different parts of the patient's body. A second connector 53 is rotatably connected to the outer side of the extension tube 2. A hanging ring 54 is rotatably connected to the front side of the second connector 53, which allows the hanging ring 54 to be multi-directionally adjustable and convenient to cooperate with the hook 52. When the tube body 1 and the extension tube 2 are bent, the hanging ring 54 hangs on the hook 52 to fix the device on the patient, which improves the practicality of the device and can meet the needs of different patients' body postures and treatment scenarios. Anti-slip strips are provided on the inner sides of the first connector 51 and the second connector 53 to increase the friction between the first connector 51 and the extension tube 2, thereby improving its stability.

[0036] Working principle: When it is necessary to adjust the length of the extension tube 2 according to the patient's actual situation, the medical staff manually pulls the extension tube 2. During the pulling process, the limiting groove 34 on the outside of the extension tube 2 will squeeze the limiting bead 32 that is stuck in it. Since the limiting bead 32 is fixed to the inner wall of the tube body 1, when it is squeezed, the limiting bead 32 will exert a force on the tube body 1, causing the tube body 1 to deform. At this time, the fixing part 31 plays a role. Its rigid material can limit the deformation range of the tube body 1 and prevent excessive deformation from affecting the normal use of the drainage tube.

[0037] As the tube body 1 deforms, the limiting bead 32 moves from its original position in the limiting groove 34, releasing the limitation on the extension tube 2. Medical staff can then stretch or retract the extension tube 2 to a suitable length according to the patient's needs. After adjustment, under the elastic force of the tube body 1, the limiting bead 32 is once again inserted into the corresponding limiting groove 34 of the extension tube 2 to fix the extension tube 2, ensuring the relative stability of the tube body 1 and the extension tube 2, and completing the length adjustment operation. This allows the device to better adapt to the actual conditions such as the depth of the anal fistula in different patients, improving the applicability of the device.

[0038] After draining the anal fistula and adjusting the length of the extension tube 2, the device needs to be fixed. Medical staff bend the tube body 1 and the extension tube 2 according to the patient's body part and posture. After bending, they rotate the first connector 51 to adjust the direction of the hook 52, and at the same time rotate the second connector 53 to adjust the direction of the hanging ring 54 so that the two can cooperate with each other. Then, the hanging ring 54 is hung on the hook 52 to fix the device on the patient. This ensures that the device will not easily loosen or shift during the patient's movement, ensuring the smooth progress of the drainage process, meeting the needs of different patients' body postures and treatment scenarios, and improving the practicality of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
