Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a foreskin expander. Background Technology

[0002] According to relevant statistics, the incidence of phimosis in newborn boys is approximately 96.5%, and the incidence of paraphimosis is approximately 99.7%. As children grow older, the foreskin and glans penis gradually separate. By puberty, the incidence of phimosis is between 30% and 40%, and the incidence of paraphimosis is around 8%. Phimosis or paraphimosis easily traps dirt and grime, fostering the growth of bacteria and other pathogens, leading to balanitis and posthitis. If inflammation recurs, it can also cause urethral meatus stenosis, resulting in difficulty urinating. Furthermore, in adulthood, phimosis or paraphimosis may affect sexual life; the foreskin may tear, causing pain and bleeding. Inadequate local hygiene may also increase the risk of gynecological diseases such as cervicitis in the partner.

[0003] Currently, the common treatment is surgical removal of the excess foreskin, allowing the glans penis to be exposed naturally, thus achieving the therapeutic goal. This surgery requires injection anesthesia and carries potential anesthetic risks. The surgery time is relatively long, generally ranging from 30 minutes to 1 hour. The surgery is relatively invasive, and postoperative incision pain is quite significant. Wound healing is relatively slow, requiring about 1 to 2 weeks for the incision to begin healing. During this period, patients need to rest and avoid strenuous exercise and penile erections, otherwise, it will affect wound healing. Utility Model Content

[0004] The purpose of this invention is to provide a foreskin expander to solve the problem of significant harm and slow recovery caused to patients when treating phimosis.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foreskin dilator, wherein the front end of the tube is inserted into the rear end of the balloon; the front end of the funnel-shaped shell is inserted into the rear end of the tube; the plug is sleeved and matched with the rear end of the inner cavity of the funnel-shaped shell, and an inflation hole is provided at the center of the plug; the plug head is sleeved and matched with the inflation hole; and the Robert clamp is used to control the opening and closing of the tube.

[0006] Preferably, a flexible connecting strip connects the outer wall of the rear end of the funnel-shaped shell to the outer wall of the front end of the plug.

[0007] Preferably, the front end of the plug is radially connected to a second flexible connecting band, and the plug head is fixed to the bottom end of the front wall of the second flexible connecting band.

[0008] Preferably, the balloon and the tube are made of one of silicone, latex, or high-molecular-weight polypropylene.

[0009] Preferably, the funnel-shaped shell, plug, plug head, flexible connecting strip one, and flexible connecting strip two are integrally injection molded.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model relates to a foreskin dilator that injects water or gas into a balloon through a tube, causing the balloon to gradually expand, thereby achieving the therapeutic purpose of dilating the phimosis opening and separating the glans from the foreskin. The dilator is simple to operate and causes less trauma to the patient, which not only reduces the pain suffered by the patient, but also greatly shortens the patient's recovery time, and is particularly easy to accept by pediatric patients.

[0021] 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.

[0022] Please see Figure 1 This utility model provides a technical solution: a foreskin dilator, wherein the front end of the tube body 2 is inserted into the rear end of the balloon 1; the front end of the funnel-shaped shell 3 is inserted into the rear end of the tube body 2; the plug body 5 is sleeved and matched with the rear end of the inner cavity of the funnel-shaped shell 3, and an inflation hole 5.1 is provided at the center of the plug body 5; the plug head 7 is sleeved and matched with the inflation hole 5.1; and the Robert clamp 8 is used to control the opening and closing of the tube body 2. The balloon 1 and the tube body 2 are made of one of the following materials: silicone, latex, or high-polymer polypropylene.

[0023] In summary, when using this treatment, first keep the balloon 1 deflated, apply ointment to the area to be dilated for 15 minutes to anesthetize it, and then disinfect it. Gently insert the balloon 1 into the foreskin opening, and then inject clean water through the funnel-shaped shell 3; or insert the plug 5 into the funnel-shaped shell 3 and inject gas through the inflation port 5.1; both clean water and gas will enter the balloon 1 through the funnel-shaped shell 3 and the tube 2, and the balloon 1 will gradually inflate, thereby achieving the therapeutic purpose of dilating the phimosis opening and separating the glans from the foreskin. At this time, use the Robert's clamp 8 to clamp the tube 2, then insert the plug 5 into the funnel-shaped shell 3 and insert the plug head 7 into the inflation port 5.1, keep it for 5-10 minutes, then deflate or drain the water from the balloon 1, and remove the balloon 1 from the foreskin opening.

[0024] The process of injecting water or air requires the use of a micro water pump or micro air pump to ensure that the injected water or air has a certain pressure, so as to generate sufficient expansion force on the balloon 1 and thus ensure the gradual expansion of the balloon 1.

[0025] The treatment of phimosis involves a gradual expansion approach, resulting in minimal trauma during the procedure (except for cases with minor adhesions). This significantly reduces pain, eliminates the need for antibiotics and painkillers, and avoids the extensive use of anesthetics. Recovery is rapid, allowing patients to leave immediately after the procedure, with minimal impact on their work, studies, and daily life.

[0026] To improve the overall integrity of the expander, prevent the plug body 5 and the plug head 7 from scattering or being lost, and enhance the convenience of storing the expander as a whole, a flexible connecting strip 4 connects the outer wall of the rear end of the funnel-shaped shell 3 to the outer wall of the front end of the plug body 5. A second flexible connecting strip 6 is radially connected to the front end of the plug body 5, and the plug head 7 is fixed to the bottom end of the front wall of the second flexible connecting strip 6. The funnel-shaped shell 3, the plug body 5, the plug head 7, the first flexible connecting strip 4, and the second flexible connecting strip 6 are integrally injection molded.

[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
