Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anal fistula seton device with quantitative adjustment and flushing functions. Background Technology

[0002] Anal fistula is a common and complex disease in anorectal surgery, and seton placement plays a crucial role in its treatment. Traditional setons have several drawbacks: They lack a precise quantitative adjustment mechanism for seton length, relying heavily on the doctor's experience, making it difficult to ensure the seton length is accurately adapted to each patient's fistula condition. Furthermore, purulent secretions within the fistula cannot be promptly cleaned, and inflammatory secretions generated during the seton placement process cannot be quickly drained through flushing, easily leading to prolonged inflammation and abscess spread. More importantly, patients cannot adjust the seton length themselves after placement. Since the recovery process of anal fistula is dynamic, the optimal seton length needs to be adjusted as the internal tissues gradually heal and repair. However, existing setons cannot meet the needs of patients adjusting the length outside the hospital, often requiring multiple trips to the hospital for adjustments. This not only causes great inconvenience to patients, increasing their medical and time costs, but may also affect the treatment effect due to the inability to adjust the length of the seton in time. For example, if the seton is too tight, it may cause excessive cutting of local tissue, ischemia, and increased pain. If the seton is too loose, it may cause poor drainage of the fistula, delayed healing, and increase the risk of infection and recurrence.

[0003] Furthermore, existing fistula setons lack a dedicated cleaning structure, making it difficult to conveniently inject cleaning fluid into the seton site, or the cleaning fluid cannot be evenly and effectively distributed within the fistula. This hinders postoperative cleaning and care, increasing the risk of infection spread and prolonging the healing process. Therefore, there is an urgent need for a new type of fistula seton that can quantitatively disseminate fluid and has a flushing function to overcome these problems. Summary of the Invention

[0004] (a) Technical problems to be solved

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.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Please see Figure 1-6 The above describes a fistula seton device with quantitative adjustment and flushing functions, which mainly consists of two parts: an adjustment buckle 1 and a seton tube 2.

[0032] The adjusting buckle 1 includes an upper buckle block 101 and a lower buckle block 102, which are connected at one end by an elastic plastic sheet. This connection allows the upper buckle block 101 and the lower buckle block 102 to rotate relative to each other, like a flexible clip structure.

[0033] The upper latching block 101 has an upper limit groove 103, and the lower latching block 102 has a corresponding lower limit groove 104. The upper limit groove 103 and the lower limit groove 104 are not only precisely aligned in position, but also have the same dimensions. When the upper latching block 101 and the lower latching block 102 are engaged, they form a complete circular hole. The size of this hole is designed to match the outer diameter of the hanging tube 2, which can stably accommodate and fix the hanging tube 2, and plays a key guiding and limiting role when adjusting the length of the hanging tube 2.

[0034] The upper buckle 101 is also provided with a clamping plate 105, which is semi-circular and corresponds to the semi-cylindrical adjustment groove 106 on the lower buckle 102. The outer diameter of the clamping plate 105 is smaller than the inner diameter of the adjustment groove 106. When the upper buckle 101 and the lower buckle 102 are engaged, the clamping plate 105 can be partially embedded in the adjustment groove 106. Through the friction with the inner wall of the adjustment groove 106 and the squeezing action on the hanging tube 2, the hanging tube 2 is initially fixed after adjustment, preventing it from sliding freely.

[0035] The upper buckle 101 is further provided with a buckle 107, and the lower buckle 102 is provided with a groove 108 that cooperates with the buckle 107. The buckle 107 is designed with a guide surface 110, which adopts a smooth bevel or arc surface design. During the buckling process, it can guide the buckle 107 to slide smoothly into the groove 108, reducing the difficulty of buckling and improving the operation efficiency. At the same time, the buckle 107 is also provided with a pressing protrusion 111. The position and shape of the pressing protrusion 111 are convenient for the user to apply force. When it is necessary to unlock the buckle 107 from the groove 108, simply press the protrusion 111. Utilizing the elastic deformation characteristics of the elastic plastic material used in the buckle 107, the buckle 107 is disengaged from the groove 108, thereby unlocking the adjustment buckle 1 and facilitating the readjustment of the length of the hanging tube 2.

[0036] The hanging tube 2 is a hollow, flexible tubular structure. This material and structural design ensures that it can pass smoothly through the fistula without causing excessive damage to the fistula tissue. Multiple irrigation holes 3 are evenly distributed on its outer wall, with the distance between adjacent irrigation holes 3 strictly controlled at 5 mm. This uniform distribution of irrigation holes 3 ensures that during cleaning, the cleaning fluid flows out from the hanging tube 2 and disperses evenly within the fistula, thoroughly and effectively cleaning the inside of the fistula.

[0037] One end of the hanging tube 2 is connected to an injection sleeve 4. The injection sleeve 4 has a funnel-like structure. Its large end is easy to connect to a syringe or other cleaning fluid injection device, and its small end is tightly connected to the hanging tube 2. This funnel-like structure can effectively reduce the resistance when injecting the cleaning fluid, so that the cleaning fluid can flow smoothly into the hanging tube 2, which facilitates the cleaning operation.

[0038] A positioning sleeve 5 is fixedly installed at one end of the hanging tube 2 near the injection sleeve 4. The outer diameter of the positioning sleeve 5 is smaller than the inner diameter of the upper limit groove 103. During assembly and use, the positioning sleeve 5 can be accurately inserted into the circular hole formed by the upper limit groove 103 and the lower limit groove 104, which plays a role in positioning and stabilizing the relative position of the hanging tube 2 and the adjusting buckle 1, preventing the hanging tube 2 from shifting or shaking during adjustment and use, and ensuring the stability and reliability of the entire hanging device. The hanging tube 2 is made of rubber or PVC material. These two materials have good flexibility, biocompatibility and corrosion resistance, which can meet the special requirements of use in human anal fistula sites.

[0039] Working principle:

[0040] In use, first carefully thread the hanging tube 2 through the patient's fistula, ensuring that the positioning sleeve 5 at one end of the hanging tube 2 is accurately positioned outside the fistula near the adjusting buckle 1. Then, gently rotate the upper buckle 101 and the lower buckle 102 to position the hanging tube 2 within the circular slot formed by the upper limit groove 103 and the lower limit groove 104. At this point, precisely adjust the length of the hanging tube 2 within the fistula according to the actual length requirements. During adjustment, the hanging tube 2 is initially fixed using the friction between the clamping plate 105 on the upper buckle 101 and the adjusting groove 106 on the lower buckle 102. Subsequently, the buckle 107 on the upper buckle 101 is engaged into the slot 108 on the lower buckle 102. The tight fit between the buckle 107 and the slot 108 further ensures that the adjusting buckle 1 locks the hanging tube 2, thereby achieving precise setting of the hanging tube 2's length. If patients or medical staff find that the length of the suture needs to be adjusted during subsequent treatment, they can adjust it themselves by operating the adjustment buckle 1, without having to go to the hospital to use complicated medical equipment and professional personnel.

[0041] When the fistula needs cleaning, connect a syringe or other cleaning solution injection device to the injection sleeve 4 at one end of the hanging tube 2, and slowly inject an appropriate amount of cleaning solution into the hanging tube 2. The cleaning solution flows inside the hanging tube 2 and is evenly sprayed into the inside of the fistula through the evenly distributed flushing holes 3 on the outer wall, providing a thorough and effective cleaning of the fistula. After cleaning, the length of the hanging tube 2 can be adjusted or other related operations can be performed as needed.

[0042] If the length of the hanging tube 2 needs to be adjusted during treatment, simply press the pressing protrusion 111 on the buckle 107 to disengage the buckle 107 from the slot 108 and release the locking state of the adjusting buckle 1. Then, rotate the upper buckle block 101 and the lower buckle block 102 again to adjust the position of the hanging tube 2 in the fistula. Use the clamping plate 105 to initially fix it with the adjusting groove 106 again, and then re-lock the buckle 107 into the slot 108 to complete the readjustment of the length of the hanging tube 2.
