Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a flushing and drainage tube for assisting in the treatment of complex high-level anal fistulas after surgery. Background Technology
[0002] Anal fistula is a common disease in proctology, referring to a chronic, pathological tract between the rectum / anal canal and the surrounding skin. Clinical manifestations are mainly recurrent local purulent discharge, pain, and itching. Surgical treatment is the primary treatment for anal fistula. For high-level complex anal fistulas, the fistula tract is located deep above the external sphincter, with multiple openings and tracts. Some tracts are complexly tortuous, often containing branches and deep dead spaces, making surgical treatment more difficult. Improper surgical handling can lead to complications such as significant postoperative pain and non-healing wounds. Therefore, it is necessary to pay attention to both the treatment of the primary internal opening and the management of the high-level fistula tract. Poor drainage of the tract can also cause serious problems such as fistula recurrence. Clinically, it is believed that thoroughly removing necrotic tissue from branches, dead spaces, and sinus tracts, and maintaining unobstructed and clean wound drainage, is of great significance for improving efficacy and preventing recurrence. Therefore, the seton technique still plays an important role in the adjuvant treatment after surgery for high-level complex anal fistulas. In clinical practice, for drainage between multiple incisions in complex anal fistulas, materials such as silk thread, rubber bands, cut disposable sterile rubber gloves, plastic tubes, and rubber tubes are often used as drainage sutures.
[0003] The drawbacks of traditional hanging-line drainage flushing materials are:
[0004] ① Drainage Effectiveness Issues: When using materials such as silk thread, rubber bands, or disposable sterile rubber gloves as seton materials for drainage in multiple complex anal fistulas with multiple incisions, the materials, due to their softness, do not cause excessive pain or discomfort to the patient. However, because these materials do not provide good support to the inside of the incision, their drainage effect on deep exudate is generally limited, and their effectiveness in clearing deep inflammation is uncertain. Furthermore, poor drainage can prolong the time the seton material remains in place, potentially leaving deep scar grooves. Such scars not only affect appearance but may also have long-term impacts on anal function.
[0005] ② Causing pain and discomfort to patients: In order to achieve better irrigation and drainage effects, plastic tubes and rubber tubes are commonly used as irrigation and drainage materials in clinical practice. However, the material of the drainage tube is relatively hard, and the diameter of the drainage tube is significantly larger than that of silk sutures, which can cause patients to experience persistent and severe pain after the drainage tube is placed. This seriously affects the patient's postoperative quality of life.
[0006] ③ Ineffective irrigation: In traditional irrigation drainage tubes, a portion of a rubber urinary catheter is often used as the irrigation drainage tube in clinical practice. However, because its diameter is significantly longer than that of a syringe tip, direct irrigation is ineffective. Therefore, it is often necessary to use hemostatic forceps to clamp part of the drainage tube tip to facilitate irrigation, which significantly increases the complexity and difficulty of the irrigation process. On the other hand, in order to effectively irrigate deep wounds, clinicians often cut side holes on the side of the drainage tube to facilitate irrigation, which is highly random and has poor controllability of clinical results.
[0007] ④ Problems with fixing the irrigation tube: Irrigation drainage tubes are often fixed at both ends by ligating with silk sutures during surgery. Because the two ends are tied together with silk sutures, the drainage effect is acceptable. However, when changing dressings later, if the irrigation treatment is performed through the head of the irrigation drainage tube, there is a possibility that medication cannot be injected. If the ligature is cut before each irrigation and then ligated again after irrigation, the process is cumbersome and inconvenient. Therefore, there is a need to provide an irrigation drainage tube for assisting in the treatment of high-level complex anal fistulas to solve the above problems. Utility Model Content
[0008] To address the shortcomings of existing technologies, this invention provides a flushing and drainage tube for adjuvant treatment of complex high-level anal fistulas after surgery, thus solving the problems mentioned in the background.
[0009] This utility model provides the following technical solution: a flushing and drainage tube for assisting in the treatment of high-level complex anal fistula after surgery, including a drainage tube body, a connector tube at one end of the drainage tube body, a flushing water outlet at the end of the drainage tube body away from the connector tube, a plurality of rhomboid water passage holes on the middle side wall of the drainage tube body, and hook and loop fasteners at both ends of the drainage tube body.
[0010] The hook and loop fastener assembly includes a male hook and loop fastener and a female hook and loop fastener. The male hook and loop fastener is located at one end of the drain tube body near the connector tube, and the female hook and loop fastener is located at one end of the drain tube body near the flushing outlet.
[0011] Preferably, the connector tube has a flushing inlet hole at its center that communicates with the interior of the drainage tube body, and the drainage tube body is connected to the syringe through the connector tube.
[0012] Preferably, the male hook and loop fastener includes a base and a clip, the clip being disposed at the center of the side of the base opposite to the drainage tube body.
[0013] Preferably, the female hook and loop fastener includes a second base and a slot, wherein the slot is located at the center of the side of the second base opposite to the drain tube body.
[0014] Preferably, the drainage tube body is a hexagonal silicone tube.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This irrigation and drainage tube, used as an adjunct treatment for high-level complex anal fistula surgery, features a connector tube and an irrigation inlet for easy connection to a syringe. The syringe tip is inserted into the irrigation inlet, making irrigation, drainage, and administration more stable and reliable. This ensures smooth flow of medication or irrigation fluid and prevents leakage. The drainage tube body adopts a hexagonal cross-section design, which provides better physical stability compared to traditional circular drainage tubes. The hexagonal design allows for more even distribution of stress on the tube wall when the patient moves or external pressure is applied, reducing the possibility of local pressure and thus lowering the risk of drainage tube dislocation or discomfort.
[0017] 2. This irrigation and drainage tube, used as an adjunct treatment for high-level complex anal fistula surgery, features a hook and loop fastener assembly. By bending the drainage tube body and inserting the male hook and loop fastener into the groove of the female hook and loop fastener, both ends of the drainage tube body can be easily fixed in the appropriate position. This facilitates the fixation of the drainage tube body during postoperative care. Furthermore, when medication needs to be changed or cleaning is required later, it can be quickly untied and re-fixed without the need for additional tools, thus avoiding the trouble of repeated ligation required by traditional drainage tubes.

[0023] 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.
[0024] Please see Figure 1-4 A flushing and drainage tube for adjuvant treatment of complex high-level anal fistula surgery includes a drainage tube body 1, a connector tube 2 at one end of the drainage tube body 1, a flushing water outlet 3 at the end of the drainage tube body 1 away from the connector tube 2, a plurality of rhomboid water passage holes 4 on the middle side wall of the drainage tube body 1, and hook and loop fasteners at both ends of the drainage tube body 1.
[0025] The hook and loop assembly includes a male hook and loop 5 and a female hook and loop 6. The male hook and loop 5 is located at the end of the drain tube body 1 near the connector tube 2, and the female hook and loop 6 is located at the end of the drain tube body 1 near the flushing outlet 3.
[0026] The connector tube 2 has a flushing inlet hole 201 in the center that communicates with the inside of the drainage tube body 1. The drainage tube body 1 is connected to the syringe through the connector tube 2. The connector tube 2 and the flushing inlet hole 201 facilitate the connection of the syringe. The front end of the syringe is inserted into the flushing inlet hole 201, which makes the process of administering medicine, flushing, and drainage more stable and reliable, ensuring that the medicine or flushing fluid can pass through smoothly and preventing liquid leakage.
[0027] The male hook and loop fastener 5 includes a base 501 and a clip 502. The clip 502 is located at the center of the side of the base 501 facing away from the drainage tube body 1. The female hook and loop fastener 6 includes a base 601 and a slot 602. The slot 602 is located at the center of the side of the base 601 facing away from the drainage tube body 1. By bending the drainage tube body 1, the clip 502 of the male hook and loop fastener 5 is inserted into the slot 602 of the female hook and loop fastener 6. This can easily fix both ends of the drainage tube body 1 in the appropriate position, which facilitates the fixation of the drainage tube body 1 during postoperative care. Furthermore, it can be quickly untied and re-fixed when medication needs to be changed or cleaning is required later, without the need for additional tools, and avoids the trouble of repeated ligation required by traditional drainage tubes.
[0028] The drainage tube body 1 is a hexagonal silicone tube. Its hexagonal cross-section design provides better physical stability compared to traditional circular drainage tubes. The hexagonal design allows for more even stress distribution on the tube wall during patient movement or external pressure, reducing the possibility of localized pressure and thus lowering the risk of tube dislocation or discomfort. The presence of prismatic water passages 4 ensures that the liquid covers the entire drainage area during flushing. Furthermore, the drainage tube body 1 is made of medical-grade silicone, which is soft, elastic, and highly biocompatible, preventing allergic or inflammatory reactions in tissues and making it suitable for long-term placement. The softness of silicone helps reduce patient pain and discomfort, especially when the drainage tube needs to be left in place for an extended period. Additionally, the smooth surface of the silicone material makes it difficult for bacteria to adhere, thus reducing the risk of infection.
[0029] The working principle is as follows: the connector tube 2 and the flushing inlet 201 are designed to facilitate the connection of a syringe. The tip of the syringe is inserted into the flushing inlet 201, which makes the infusion, flushing and drainage more stable and reliable. This ensures that the medicine or flushing solution can pass through smoothly and prevents liquid leakage. By bending the drainage tube body 1, the clip 502 of the male hook and loop fastener 5 is inserted into the groove 602 of the female hook and loop fastener 6. This can easily fix both ends of the drainage tube body 1 in the appropriate position, which facilitates the fixation of the drainage tube body 1 during postoperative care. Moreover, when it is necessary to change the medicine or clean it later, it can be quickly untied and re-fixed without the need for additional tools, and it also avoids the trouble of repeated ligation required by traditional drainage tubes.
[0030] Furthermore, the drainage tube body 1 adopts a hexagonal cross-section design. Compared with the traditional circular drainage tube, this structure can provide better physical stability. The hexagonal design allows the tube wall to distribute stress more evenly when the patient moves or external pressure is applied, reducing the possibility of local pressure and thus reducing the risk of drainage tube dislocation or causing discomfort. By setting the prismatic water passage 4, it is ensured that the liquid can cover the entire drainage area during flushing.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
