Embodiment 1

[0048] refer to Figure 1-3 As shown, the present invention provides a urethral dilatation catheter, comprising: a three-lumen urinary catheter 20 coated with a hydrophilic coating on the outside; the three-lumen urinary catheter 20 includes a drainage channel 203 arranged in the middle; the drainage channel 203 is provided with a probe core 10; the probe core 10 is provided with a light conduction channel 101 and a reserved operation channel 102 with a circumference of 4-6mm; the reserved operation channel 102 is used to operate the instrument deeply; the light An optical fiber bundle 103 is pierced inside the conduction channel 101 ; the optical fiber bundle 103 is connected to the image transmission device 40 .

[0049] In order to make the urethral dilatation catheter conform to the urethral structure, the end of the probe 10 that penetrates into the urethra is provided with a bending angle; the angle between the bending angle and the vertical line of the three-lumen cathe...

Embodiment 2

[0056] Compared with Example 1, this example differs only in the composition of the hydrophilic coating.

[0057] In the present embodiment, the preparation method of the hydrophilic coating is as follows: weigh the following components with a balance: polyvinylpyrrolidone 7g, ascorbic acid 2g, sodium chloride 4g, polydopamine 2g, tributyl citrate 0.7g, Ethylene glycol dimethacrylate 7g, absolute ethanol 60g and deionized water 40g. After weighing, add absolute ethanol, deionized water and polyvinylpyrrolidone into the container, stir at room temperature until the polyvinylpyrrolidone is completely dissolved; then add ascorbic acid, polydopamine, tributyl citrate and ethyl dimethacrylate Glycol ester, stirred for 45 minutes; then added sodium chloride, stirred until the solution was clear, and the hydrophilic coating solution was obtained. The hydrophilic coating solution is coated on the surface of the three-lumen urinary catheter by dipping, spraying or brushing; the three-...

Embodiment 3

[0059] Compared with Example 1, this example differs only in the composition of the hydrophilic coating.

[0060] In the present embodiment, the preparation method of the hydrophilic coating is as follows: Weigh the following components with a balance: 11 g of polyethylene oxide, 3 g of ascorbic acid, 6 g of potassium chloride, 3 g of polydopamine, 1 g of acetyl tributyl citrate, Ethylene glycol methacrylate 9g, butanone 70g and deionized water 50g. After the weighing is completed, add methyl ethyl ketone, deionized water and polyethylene oxide into the container, stir at room temperature until the polyethylene oxide is completely dissolved; then add ascorbic acid, polydopamine, acetyl tributyl citrate and ethylene glycol dimethacrylate ester, stirred for 60 minutes; then potassium chloride was added, and stirred until the solution was in a clear state to obtain a hydrophilic coating solution. The hydrophilic coating solution is coated on the surface of the three-lumen urinar...

Abstract

The invention provides a urethral dilation catheter. The urethral dilation catheter comprises a three-cavity urinary catheter; a drainage channel is arranged in the three-cavity urinary catheter; a probe core is arranged in the drainage channel; a light conduction channel and a reserved operation channel with the circumferential diameter being 4-6 mm are arranged in the probe core. The reserved operation channel is used for deeply operating an instrument; an optical fiber bundle is arranged in the light conduction channel in a penetrating manner; an image transmission device is arranged at thetail part of the probe core; the optical fiber bundle is connected with the image transmission device; and a hydrophilic coating is coated outside the three-cavity urinary catheter. The urethral dilation catheter is high in visualization, convenient to operate and high in safety.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a urethral dilation catheter and a medical device including the urethral dilation catheter. Background technique [0002] Difficult urinary catheterization is one of the common clinical problems. Most non-urologists are helpless in the above situation and can only seek help from urologists or perform cystostomy. Therefore, the solution to the problem of difficult catheterization is a clinical pain point. [0003] With the integration and rapid development of medical imaging technology and robot industry, robot technology will greatly change the face of all walks of life: in agriculture, industry and other fields, with the help of new technologies, the original specialized knowledge can be mastered by ordinary people, robots Technology liberates people from boring labor, and more and more simple, repetitive, and dangerous tasks are completed by artificial intellig...
