Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a visualized urethral dilator. Background Art

[0002] As the population ages, the incidence of some aging diseases such as prostate hyperplasia is getting higher and higher. Some congenital stenosis, trauma and iatrogenic injury cause urethral stenosis. For example, mild urethral stenosis can be treated with urethral dilation and prostate hyperplasia can be treated with cystoscopic exploration. For example, the patent document with application number CN201922363141.0 discloses a retractable and bendable visual urethral dilator. By setting a retractable sheath, the retractable sheath can be retracted according to specific needs, so that the lens and the bendable section can be retracted or extended from the retractable sheath, so that the endoscopic probe can be rigidly guided by the retractable sheath when probing into the corresponding surgical site.

[0003] However, similar solutions mentioned above require multiple insertions from thin to thick into the urethra for dilation, and each insertion will increase the pain of the patient. Multiple insertions will cause safety hazards. After use, it is not convenient to disinfect the interior due to the integrated structure, and the dilation component cannot fit the inner wall of the urethra, resulting in uneven force during dilation, thus causing damage to the urethra. Therefore, in view of this, the existing structural deficiencies are studied and improved, and a visual urethral dilator is proposed. Utility Model Content

[0004] The utility model aims to provide a visualized urethral dilator, which has the characteristics of slow dilation after one insertion to reduce the pain of the patient, and is easy to disassemble and convenient for internal disinfection.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is a visualized urethral dilator, comprising a support tube that passes through the head and tail, a trachea for conveying gas is slidably connected through the internal channel of the support tube, the trachea is longer than the support tube, an inflatable ball is arranged at the tail of the trachea, a plurality of air outlets are opened at the head of the trachea, and a rubber sleeve is sheathed on the outside of the trachea at the position of the air outlet;

[0006] A threaded fixing plate is provided at the trachea head, a threaded endoscope probe is provided at the fixing plate head, a threaded connecting plate is provided at the supporting tube head, both sides of the rubber sleeve are sealed and bonded to the fixing plate and the connecting plate respectively, and a sealing ring that fits the trachea is provided on the inner side of the connecting plate.

[0007] Furthermore, the outer diameter of the support tube is 4-6 mm.

[0008] Furthermore, a group of mutually symmetrical handles are fixedly arranged on the outer side of the rear end of the support tube.

[0009] Furthermore, the support tube is made of stainless steel.

[0010] Furthermore, the air outlets are arranged at equal distances from each other.

[0011] Furthermore, the rubber sleeve is configured to be corrugated.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) The utility model inserts one side with the endoscopic probe into the patient's body through the mutual cooperation between the various components. After approaching the stenosis, the trachea is pushed forward, and the trachea drives the endoscopic probe forward. The position of the stenosis is observed through the display screen of the endoscopic probe, and the endoscopic probe is passed through the stenosis. At this time, the inflatable ball is pressed, and the gas in the inflatable ball enters the rubber sleeve through the air outlet on the trachea, and slowly swells up so that the rubber sleeve fits the inner wall of the urethra. The diameter of the bulging rubber sleeve is controlled by the pressing force, and the urethra can be expanded to different degrees, thereby avoiding multiple insertions, achieving slow expansion with one insertion, and avoiding multiple insertions that aggravate the patient's pain.

[0014] (2) The components of the utility model are connected in a detachable manner by threaded connection or bonding, which is simple and easy to use during disassembly. After use, the utility model can be disassembled, thereby facilitating the cleaning and disinfection of the components. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 and 2The visualized urethral dilator shown in the figure comprises a support tube 1 which passes through the head and tail. It should be noted that the support tube 1 is made of stainless steel, which supports the urethral opening and increases the service life of the support tube 1. The outer diameter of the support tube 1 is 4-6 mm. When inserted into the urethral opening, the smaller diameter can reduce the pain of insertion. A group of symmetrical handles 3 can be fixedly arranged on the outer side of the tail of the support tube 1 to facilitate single-handed support and maintain the stability of the support tube 1. An air pipe 202 for conveying gas is slidably connected through the internal channel of the support tube 1. The length of the air pipe 202 is greater than that of the support tube 1, which facilitates the penetration of the air pipe into the narrow area. An inflatable ball 204 is arranged at the tail of the air pipe 202. A plurality of air outlets 203 are provided at the head of the trachea 202, and a rubber sleeve 201 is provided on the outside of the trachea 202 at the location of the air outlets 203. The rubber material is relatively soft and can fit the skin, which is beneficial to reducing the pain during expansion; it should be noted that the air outlets 203 are arranged at equal distances, so that the rubber sleeve 201 can bulge outward evenly, avoiding uneven force during expansion and preventing damage to the urethra; the rubber sleeve 201 is arranged in a corrugated shape, and can maintain a compressed state before reaching the narrow area, which is beneficial to reducing the insertion depth of the support tube 1, and the inflatable ball 204 inflates the rubber sleeve 201 through the air outlets 203 on the trachea 202 to expand the rubber sleeve 201;

[0022] like Figure 3 As shown, a threaded fixing plate 501 is provided at the head of the trachea 202. The threaded connection ensures convenient disassembly and disinfection while ensuring the stability of the connection between the components. A threaded endoscope probe 4 is provided at the head of the fixing plate 501 for accurately observing the narrow area inside the urethra. Figure 4 A threaded connecting plate 502 is provided at the head of the support tube 1. It should be noted that the two sides of the rubber sleeve 201 are sealed and bonded to the fixing plate 501 and the connecting plate 502 respectively to prevent the rubber sleeve 201 from leaking. A sealing ring 503 that fits the air pipe 202 is provided on the inner side of the connecting plate 502 to further prevent the rubber sleeve 201 from leaking and make the air pipe 202 more stable when sliding.

[0023] When the utility model is used, the doctor holds the handle 3 to insert the side with the endoscope probe 4 into the patient's body, and observes the situation in the urethra through the display screen of the endoscope probe 4. When the endoscope probe 4 is located in front of the narrow area, the hand holding the handle 3 remains still, and the other hand pushes the trachea 202, thereby driving the endoscope probe 4 to move forward and stretching the rubber sleeve 201 forward until the endoscope probe 4 passes through the narrow area. Since the rubber sleeve 201 is in a stretched state when passing through the narrow area, its diameter is smaller than the diameter of the endoscope probe 4, so that the patient's pain can be reduced when passing through. At this time, the inflatable ball 204 is pressed, and the inflated ball The gas in 204 enters the rubber sleeve 201 through the air outlet 203 on the trachea 202, and slowly swells so that the rubber sleeve 201 fits against the inner wall of the urethra. The diameter of the bulged rubber sleeve 201 is controlled by the pressing force, so that the urethra can be expanded and the narrow part can be slowly expanded. After the expansion is completed, the rubber sleeve 201 is slowly deflated, and the urethra at this point is observed through the endoscopic probe 4. The dilator is then pulled out to end the treatment. The rubber sleeve 201 and the endoscopic probe 4 are removed from the support tube 1 by loosening the connecting plate 502 and the fixing plate 501, and each part is cleaned and disinfected separately.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
