Description

Technical Field

[0001] The utility model relates to the technical field of urethral dilators, in particular to a novel multi-functional urethral dilator. Background Art

[0002] A urethral dilator is a medical device used to treat urethral obstruction caused by urethral stricture or other urethral diseases. Urethral stricture refers to the narrowing or occlusion of the urethral lumen, resulting in difficult or complete obstruction of urine excretion. Urethral dilators are usually soft and smooth instruments designed to gradually dilate the urethra and restore its normal patency. They can be of different shapes and sizes to meet the needs of different patients and treatment requirements.

[0003] However, the existing medical urethral dilators have the following problems in the process of use: Commonly, a urethral dilator consists of several stainless steel solid rods of different thicknesses. According to the needs of the urethra, a solid rod suitable for the thickness of the urethra is selected and inserted into the urethra for dilation. There is no gradual process when inserting it into the urethra. Usually, the urethra is directly dilated. During the urethral dilation process, such sudden dilation is likely to cause urethral stress reaction and damage the urethra, increasing the pain of the patient. Therefore, corresponding technical solutions are needed to solve the existing technical problems. Content of the Utility Model

[0022] Please refer to Figures 1-5, the present utility model provides a technical solution: a novel multi-functional urethral dilator, which includes an adjustable rod-shaped urethral device and a liquid guiding mechanism installed on the adjustable rod-shaped urethral device. The adjustable rod-shaped urethral device includes a handle 1, an identification plate 2, a pressing airbag pad 3, an air duct 4, an inflatable airbag tube 5 and an outer tube 6. The handle 1 and the inflatable airbag tube 5 are respectively installed on both sides of the identification plate 2. Two groups of through holes 7 are symmetrically arranged on the surface of the identification plate 2. There are two groups of pressing airbag pads 3, which are symmetrically fixed on both sides of the handle 1. The two groups of pressing airbag pads 3 are respectively connected to the two groups of air ducts 4. The air ducts 4 pass through the through holes 7 and are connected to the ends of the inflatable airbag pads. The outer tube 6 is fixed on the outside of the inflatable airbag pads. An inner cavity 8 is formed inside the inflatable airbag tube 5. The liquid guiding mechanism includes an airbag ball 9, a sealing plate 10, a liquid storage container 11, a bent tube 12 and a drainage tube 13. The lower end of the airbag ball 9 is communicated with the sealing plate 10. The airbag ball 9 is similar to a medical airbag ball and contains a small amount of gas, which is mainly used to discharge the liquid medicine below. The sealing plate 10 is threadedly arranged on the liquid storage container 11. The lower end of the liquid storage container 11 is connected to the bent tube 12. The bent tube 12 passes through the identification plate 2 and is connected to the drainage tube 13. The drainage tube 13 is placed inside the inner cavity 8 and a liquid discharge hole 14 is formed at the end. The liquid discharge hole 14 is located at the end of the inflatable airbag tube 5.

[0023] Further improved, as Figure 4 shown: The identification plate 2 is in a disc-shaped structure and is made of a transparent material. Position scale lines 15 are engraved on the identification plate 2, which is convenient for medical staff to perform more accurate operations during the operation.

[0024] Further improved, as Figure 2 shown: The inflatable airbag tube 5 is in a columnar structure in the middle. Deformation grooves 16 are formed on the surface of the inflatable airbag tube 5. Several groups of deformation grooves 16 are concentrically distributed. The cross-section of the inflatable airbag tube 5 is in an overall laminated structure. In the inflated state, the inflatable airbag tube 5 expands adaptively, so as to achieve the purpose of adjusting the diameter of the urethral dilator.

[0025] Further improved, as Figure 2 shown: The outer tube 6 includes arc-shaped plates 17 and silicone connecting pieces 18. There are several groups of arc-shaped plates 17, which are annularly distributed. Adjacent two groups of arc-shaped plates 17 are connected by silicone connecting pieces 18. The outer tube 6 is formed into a rod-shaped structure surrounded by the arc-shaped plates 17 and the silicone connecting pieces 18, which is similar to the existing urethral dilator and is convenient for operation.

[0026] Further improved, as Figure 5 shown: Several groups of sliding grooves 19 are arranged on the surface of the identification plate 2. Several groups of arc-shaped plates 17 are correspondingly slidably arranged in several groups of sliding grooves 19, which is convenient for the arc-shaped plates 17 to perform stable position adjustment along the identification plate 2.

[0027] Further improved, as Figure 2As shown: The silicone connecting piece 18 has an arc-shaped structure and is made of medical silicone material. The surface of the silicone connecting piece 18 has a laminated structure, and such a laminated design facilitates passive adjustment in cooperation with the adjustment of the internal expansion airbag tube 5.

[0028] Specifically, the diameter of the outer tube 6 is between 18 mm and 24 mm, the minimum diameter of the adjustable rod-shaped urethral device is 18 mm, and the maximum diameter is 24 mm. It can be adjusted to a certain extent according to actual needs, facilitating the introduction of the urethral dilator into the urethra for dilation operations.

[0029] During use: Preparation work of the present utility model:

[0030] The patient should operate under the guidance of a doctor or nurse to ensure a clean and sterile environment and ensure that the patient is in a comfortable position. The patient may need to lie flat or supine.

[0031] Disinfection and preparation:

[0032] The doctor or nurse will disinfect the urethral orifice to reduce the risk of infection.

[0033] Inserting the dilator:

[0034] The doctor or nurse gradually inserts the end of the urethral dilator into the patient's urethral orifice while making appropriate gentle advances.

[0035] Dilation process:

[0036] During the process of gradually inserting the dilator, according to the patient's condition and the diameter of the urethral orifice, when it is necessary to increase the diameter of the urethral dilator, the medical staff can press the pressure airbag pads 3 on both sides of the handle 1, and introduce the air flow in the pressure airbag pads 3 into the expansion airbag tube 5. The expansion airbag tube 5 expands and drives the outer tube 6 to expand outward, so as to achieve the purpose of adjusting the diameter of the urethral dilator. When it is necessary to introduce the medicine into the urethral orifice, the staff can pre-introduce the medicine into the liquid storage container 11 and seal the sealing plate 10. The medical staff can squeeze the medicine into the drainage tube 13 by pressing and introduce it into the urethral orifice through the drainage tube 13.

[0037] Completion and cleaning:

[0038] After the dilation process is completed, the doctor or nurse slowly removes the dilator from the urethra, and finally disinfects and cleans the urethral orifice to ensure hygiene and prevent infection.
