Description

Technical Field

[0001] This invention relates to the field of endoscopy technology, and in particular to a therapeutic endoscope with ultrasound functionality. Background Technology

[0002] Cystoscopy is a commonly used diagnostic and therapeutic instrument in urology, widely used for screening bladder lesions and minimally invasive surgery. With the help of endoscopic imaging systems, the morphology of the bladder wall tissue can be directly observed, providing intuitive imaging evidence for disease diagnosis. The current medical cystoscopes are mature, divided into two basic types: rigid and flexible. They are equipped with imaging, irrigation, and biopsy components to form a standardized diagnostic and therapeutic equipment system. The equipment is frequently used in routine clinical physical examinations, hematuria screening, postoperative follow-up, and bladder tumor biopsy. Urology departments at all levels of hospitals have them routinely. With the popularization of urinary system disease screening, the frequency of endoscopy use continues to increase. Related consumables, imaging display equipment, and operating aids are also continuously iterated and improved, making it an indispensable medical device for non-invasive examination of urinary system diseases.

[0003] Patent CN113476004A discloses a hysteroscope and an endoscopic treatment system, comprising a working endoscope tube, an endoscope body, and a water channel assembly. The working endoscope tube, endoscope body, and water channel assembly are hollow structures, sequentially connected to form an instrument channel, which can serve as an overflow channel or an insertion channel for a treatment instrument. A first docking portion is provided at the end of the water channel assembly furthest from the working endoscope tube, and this first docking portion is used to connect to a second docking portion on the overflow channel or the treatment instrument. Its structure is compact, it can be used in conjunction with other treatment instruments, and it has high versatility.

[0004] There are still some problems with the use of endoscopes.

[0005] Endoscopic aspiration of fluid from lesions is a common minimally invasive procedure. Lesions often produce thick, viscous pus and blood clots, which can easily clog the endoscopic channel if directly aspirated. The industry generally uses a method of diluting the fluid with an irrigation solution followed by negative pressure aspiration. The diluted fluid contains necrotic tissue, blood clots, mucosal debris, and other impurities. Under negative pressure, all of this flows into the suction device. Small impurities tend to accumulate in the suction tubing, filter chamber, and negative pressure pump structure. Frequent and prolonged use can cause tubing blockage and reduced suction, requiring frequent shutdowns for disassembly and cleaning, significantly disrupting the treatment process. Summary of the Invention

[0006] The purpose of this application is to provide a therapeutic endoscope with B-ultrasound function, which realizes the connection between the negative pressure adsorption pipe and the valve, and then the body fluid collection enters the interior of the connecting pipe through the endoscope tube, enters the interior of the branch pipe through the second pipe on the connecting pipe, and then is concentrated in the collection bottle. The collection bottle collects the impurities in the collected fluid, and prevents the impurities from entering the negative pressure adsorber through the valve and causing blockage.

[0007] To achieve the above objectives, this application provides the following technical solution: a therapeutic endoscope with B-ultrasound function, comprising an endoscope body, a tube fixedly connected to the end of the endoscope body, a connector mounted on the tube, an adjustment disc at the top of the endoscope body, an eyepiece fixedly connected to one end of the endoscope body opposite to the tube, a rubber cover mounted on the eyepiece, and an optical fiber connector fixedly connected to one side of the endoscope body; It also includes a diversion component, a storage component, and a fastening component.

[0015] In summary, the present invention has the following beneficial effects: 1. The present invention has a reasonable structure. When it is necessary to extract the collected fluid, the knob is turned to connect the round hole and the first pipe. The flushing fluid enters the connecting pipe through the first pipe on the inlet pipe, and then is diluted on the lesion site through the endoscope tube. Then the knob is turned to connect the round hole and the second pipe, and the collected fluid on the lesion site is extracted through the second pipe.

[0016] 2. In this invention, the pipe of the suction device is connected to the valve. When the suction tube is opened, the inside of the collection bottle is under negative pressure.

[0030] The working principle of this invention is as follows: When it is necessary to extract the collected fluid, the knob 209 is turned to connect the round hole 207 with the first pipe 202. The flushing fluid enters the connecting pipe 2 through the first pipe 202 on the inlet pipe 203, and then is diluted on the lesion site through the endoscope tube 101. Then the knob 209 is turned to connect the round hole 207 with the second pipe 204, and the collected fluid on the lesion site is extracted through the second pipe 204.

[0031] Connect the suction tube to the valve 305, open the suction tube 304, and when drawing, the inside of the collection bottle 301 is under negative pressure. The collected liquid will enter the inside of the insertion tube 3 through the branch tube 205 on the second tube 204. The bottom end of the insertion tube 3 is inserted into the collection bottle 301. The collection bottle 301 will collect the collected liquid and its impurities in a concentrated manner, preventing the collected liquid and impurities from entering the inside of the suction device through the valve 305 and causing blockage.

[0032] When disassembling the collection bottle 301 to clean the collected liquid, pull the lever 409 upwards. The lever 409 will then move the crossbar 408. The movement of the crossbar 408 will push the clamping plate 404 to move through the pull plate 407. A slider 403 is fixedly connected to the inner wall of the clamping plate 404. The movement of the clamping plate 404 will cause the slider 403 to slide inside the slide groove 402, thereby facilitating the removal of the rubber pad 405 on the inner wall of the clamping plate 404 from the surface of the insertion tube 3, and the collection bottle 301 on the insertion tube 3 can be pulled out to clean the collected liquid.
