Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an implantable dilator and a urinary incontinence treatment device. Background Art

[0002] Urinary incontinence is a common condition in both men and women, especially in the elderly. For men, the main causes of urethral stress incontinence are surgical procedures of the minor pelvis, especially radical prostatectomy, and urological endoscopic procedures of the prostate and urethra, which may cause sphincter damage. Stress urinary incontinence is a type of urinary incontinence characterized by involuntary urination under physical pressure. In the early stages of the disease, it can be improved by conservative measures, such as gymnastics to strengthen the pelvic floor or biofeedback and electrical stimulation. For more severe degrees of incontinence, surgical treatment is required.

[0003] For male patients with urinary incontinence, two solutions are usually adopted in the past. One is to wear adult diapers, and the other is to use a penis clamp to clamp the patient's penis. If the patient chooses to wear adult diapers, the patient will feel unbearable heat in summer, and will feel uncomfortable after urinating, and it is easy to breed bacteria and cause infection. Frequent replacement of adult diapers will increase the cost of use; when the patient uses a penis clamp, since the urethra is located in the lower center of the penis and extends from the root to the front end, the penis clamp is directly clamped on the patient's penis position to tighten the urethra to prevent urinary incontinence. However, in the above method, the penis clamp is prone to the problem of the skin of the penis being clamped into the penis clamp during use, which may cause pain or injury to the patient.

[0004] In order to solve the above problems, the industry has developed a suspension mesh for treating male urinary incontinence. The suspension mesh can be implanted in the human body and fixed on the pelvic bone. The patient's urethra is suspended by the suspension mesh, and then the corresponding pressure is applied to the urethra. The pressure is just enough to prevent the patient from leaking urine under pressure (such as coughing or sneezing). However, this implantable suspension mesh cannot adjust the pressure according to demand (for example, the pressure needs to be reduced to facilitate emptying of urine), and cannot achieve a good treatment effect. Utility Model Content

[0005] The purpose of the utility model is to provide an implantable dilator and a urinary incontinence treatment device, which can adjust the pressure applied to the urethra according to needs to achieve a better treatment effect.

[0006] In order to achieve the above-mentioned object, the utility model provides an implantable dilator for treating urinary incontinence in combination with a suspension mesh, comprising:

[0007] The dilator body is connected to the suspension mesh, the top of the dilator body is in contact with the outer wall of the urethra and can be deformed, and the bottom of the dilator body has a fixed shape;

[0008] An injection seat is connected to the dilator body, and is used to inject fluid into the dilator body so that the top of the dilator body bulges outward and squeezes the outer wall of the urethra. The injection seat is also used to extract the fluid in the dilator body so that the top of the dilator body is recessed inward.

[0009] Optionally, a plurality of rings for threading the suspension mesh are provided on the side walls and / or the bottom wall of the expander body.

[0010] Optionally, a plurality of sutures for connecting the suspension mesh are pre-buried in the bottom.

[0011] Optionally, at least one pair of wing plates for connecting the suspension mesh are provided on opposite sides of the bottom.

[0012] Optionally, the wing plate is formed by extending outward from the expander body.

[0013] Optionally, the wing plate is a mesh structure, and one end of the wing plate is pre-buried in the expander body.

[0014] Optionally, the injection seat is fixedly mounted on the bottom.

[0015] Optionally, the injection seat is connected to the expander body through a catheter.

[0016] Optionally, the expander body is a hollow silicone pad.

[0017] Based on this, the utility model also provides a urinary incontinence treatment device, including a suspension mesh and the implantable expander as described above.

[0018] In the implantable dilator and urinary incontinence treatment device provided by the utility model, injecting fluid into the dilator body through the injection seat can exert higher pressure on the urethra or extract the fluid in the dilator body to reduce the pressure on the urethra, thereby achieving better treatment effect. In addition, the implantable dilator can be mass-produced in engineering and used in conjunction with the suspension mesh on the market, with good economic benefits and practicality.

[0032] The expander body 101 is connected to the suspension mesh 200, the top of the expander body 101 is in contact with the outer wall of the urethra 300 and can be deformed, and the bottom of the expander body 101 is fixed in shape;

[0033] The injection seat 102 is connected to the dilator body 101. The injection seat 102 is used to inject fluid into the dilator body 101 so that the top of the dilator body 101 bulges outward and squeezes the outer wall of the urethra 300. The injection seat 102 is also used to extract the fluid in the dilator body 101 so that the top of the dilator body 101 is recessed inward.

[0034] The present invention can inject fluid into the expander body 101 through the injection seat 102 to apply higher pressure to the urethra 300 or extract the fluid in the expander body 101 to reduce the pressure on the urethra 300, thereby achieving a better treatment effect. In addition, the implantable expander 100 can be mass-produced in engineering and used in conjunction with the suspension mesh 200 on the market, which has good economic benefits and practicality.

[0035] In this embodiment, a plurality of rings 103 for threading the suspension mesh 200 are provided on the side wall and / or the bottom wall of the expander body 101. The rings 103 are provided to facilitate the connection between the expander body 101 and the suspension mesh 200, so as to adapt to the existing suspension mesh 200 on the market. As a preferred example in this embodiment, when specifically connected, the two ends of the suspension mesh 200 can be passed through the rings 103 and the pelvic bone respectively and then sutured and fixed, similar to the fixing method of using a belt to pass through the belt buckle on the pants.

The utility model does not impose any restrictions on this, and a matching design can be made according to the suspension requirements of the suspension mesh 200.

[0037] The suspension mesh 200 includes but is not limited to a PP mesh or a titanium-plated PP mesh, and its shape is not limited to a sheet or a belt, or a combination of a sheet and a belt.

[0038] In this embodiment, the injection seat 102 is directly fixedly mounted on the bottom of the expander body 101, which is equivalent to fixing the injection seat 102 and the expander body 101 as one body. Specifically, the injection seat 102 and the expander body 101 can be integrally formed, or can be independently manufactured first and then fixed as one body by hot melting or the like, and the present invention does not limit this.

[0039] Preferably, the expander body 101 is made of a soft and biocompatible material. In this embodiment, the expander body 101 is a hollow silicone pad, that is, made of silicone. The top of the expander body 101 fits the outer wall of the urethra 300 and can be deformed to a certain extent, and the bottom is flat and does not deform.

[0040] Preferably, the injection seat 102 can be made of silicone or titanium alloy, which has good self-sealing properties and good biocompatibility.
