Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a duct stent for hypospadias repair surgery. Background Technology

[0002] Hypospadias is a congenital malformation of the urinary system in which the urethral opening is abnormally positioned, usually located on the ventral side of the penis or in the perineum. Hypospadias repair surgery is a procedure used to correct this malformation. By repairing the urethra, the urethral opening is restored to its normal position, and a new urethral passage is constructed to improve the patient's urinary function and appearance.

[0003] Following hypospadias surgery, a catheter is typically placed in the newly constructed urethra to prevent urethral stricture. The catheter is left in place for an extended period to maintain urethral patency through physical support and prevent adhesions and stricture during healing. Alternatively, for a period after surgery, doctors may periodically use a urethral dilator to dilate the urethra. The dilator's mechanical action opens up any narrowing of the urethra, maintaining its normal diameter.

[0004] Prolonged indwelling catheters disrupt the normal physiological barrier of the urethra, making it easier for bacteria to invade and increasing the risk of urinary tract infections (UTIs). UTIs not only cause pain but can also affect surgical site healing and even lead to more serious urinary system complications. Long-term catheter irritation can also cause bladder muscle hypersensitivity and spasms. These spasms can cause frequent urinary urgency and pain, severely impacting the patient's quality of life and causing significant inconvenience. Urethral dilation is an invasive procedure, and each dilation causes some damage and irritation to the urethral mucosa. Patients experience pain and discomfort during dilation, and this pain accumulates with each dilation session, placing a significant psychological and physiological burden on the patient. Utility Model Content

[0005] Therefore, this utility model provides a hypospadias repair surgical conduit stent to solve the problems existing in the above-mentioned technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hypospadias repair surgical stent includes a tube body, the length of which is greater than the urethral anastomosis length, and the tube body is placed inside the urethra. A drainage hole is provided on the side wall of the tube body placed inside the urethra, the drainage hole penetrating the side wall of the tube body for draining urethral secretions. A fixation hole is provided on the side wall of the tube body placed outside the urethra, the fixation hole penetrating the side wall of the tube body for fixing the tube body with sutures.

[0008] Optionally, the pipe body is made of medical-grade silicone.

[0009] Optionally, the flow guide holes are provided in multiple sets, and the multiple sets of flow guide holes are spaced apart on the side wall of the pipe body along the length direction of the pipe body. Each set includes multiple flow guide holes, and the multiple flow guide holes are distributed in a circumferential array on the side wall of the pipe body.

[0010] Optionally, three fixing holes are provided, and the three fixing holes are distributed in a circumferential array on the side wall of the pipe body.

[0011] Optionally, the tube body is 1-2 cm longer than the urethral anastomosis length.

[0012] This utility model has at least the following beneficial effects:

[0013] This invention features a tube body whose length exceeds that of the urethral anastomosis. The tube body can be inserted into the urethral anastomosis and then fixed to the glans penis via a suture through a fixing hole at the front end of the tube body. Simultaneously, a drainage hole on the side wall of the tube body inside the urethra allows urethral secretions to flow into the tube body and then drain out through the front end, preventing urethral infection. By replacing the bladder catheter with a short tube, patient discomfort is reduced, and the frequency of urethral dilation is decreased, thus preventing urethral stricture.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," "fourth," etc. (if present), in the specification, claims, and accompanying drawings of this utility model are intended to distinguish the objects they refer to. For solutions with a sequential flow, this terminology need not be interpreted as describing a specific order or sequence; for solutions with device structures, this terminology does not distinguish between matters of importance or positional relationships.

[0024] Furthermore, the terms “comprising,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may also include other steps or units that are not expressly listed but are inherent to these processes, methods, products, or devices, or steps or units added based on further optimizations of the inventive concept.

[0025] like Figures 1-4 As shown, this utility model discloses a urethral 4 hypospadias repair surgical tube support, including a tube body 1. The length of the tube body 1 is greater than the anastomosis length of the urethra 4, and the tube body 1 is placed inside the urethra 4. A drainage hole 2 is opened on the side wall of the tube body 1 placed inside the urethra 4. The drainage hole 2 penetrates the side wall of the tube body 1 and is used to drain secretions from the urethra 4. A fixing hole 3 is opened on the side wall of the tube body 1 placed outside the urethra 4. The fixing hole 3 penetrates the side wall of the tube body 1 and is used to fix the tube body 1 with sutures.

[0026] The aforementioned tube body 1 can be made of soft medical silicone material. The length of the tube is slightly longer than the anastomosis length of the urethra 4, generally 1-2 cm. The front end of the tube body 1 can extend out of the urethra 4. A fixing hole 3 is opened in the part of the tube body 1 that extends out of the urethra 4. The fixing hole 3 is opened on the side wall of the tube body 1 and penetrates through the side wall of the tube body 1. One end of the suture can be sewn to the glans of the patient through the fixing hole 3 on the side wall of the tube body 1, and the other end can be passed through the fixing hole 3 and wrapped and fixed to the tube body 1, thereby ensuring that the tube body 1 can be fixed in the patient's urethra 4.

[0027] In addition, a drainage hole 2 is opened on the side wall of the tube body 1, which can guide the secretions between the tube body 1 and the patient's urethra 4 into the interior of the tube body 1, so that they can flow out along the opening at the front end of the tube body 1.

[0028] The aforementioned pipe body 1 is made of a No. 10 silicone short tube with holes in its side wall. When fixing, it is fixed with a 5-0 round needle and non-absorbent nylon thread. At the same time, the fixing is moderate, neither too tight nor too loose.

[0029] In a further embodiment, the guide holes 2 are provided in multiple sets, and the multiple sets of guide holes 2 are spaced apart on the side wall of the pipe body 1 along the length direction of the pipe body 1. Each set includes multiple guide holes 2, and the multiple guide holes 2 are distributed in a circumferential array on the side wall of the pipe body 1.

[0030] To ensure the effectiveness of the drainage, multiple sets of drainage holes 2 are provided and spaced along the length of the pipe body 1. In addition, multiple drainage holes 2 can be provided in each set, and the multiple drainage holes 2 in each set are spaced apart on the circumference of the pipe body 1.

[0031] In one specific embodiment, three groups of guide holes 2 can be set, with the three groups equally spaced, each group having four guide holes 2, and the four guide holes 2 distributed in a circumferential array around the periphery of the pipe body 1.

[0032] In one specific embodiment, three fixing holes 3 are provided, and the three fixing holes 3 are distributed in a circumferential array on the side wall of the pipe body 1.

[0033] The aforementioned fixing holes 3 are provided in three directions to fix the pipe body 1 from three directions, ensuring the stability of the pipe body 1.

[0034] This invention significantly reduces the occurrence of stenosis after surgery for severe hypospadias by setting a tube body 1 that is slightly longer than the anastomosis length of urethra 4, while avoiding the drawbacks of prolonged tube placement time or periodic urethral dilation.

[0035] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0036] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0037] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments.
