Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to an endoscopic ultrasonic small probe water bladder catheter. Background Art

[0002] Small-probe endoscopic ultrasound is a crucial diagnostic tool in gastroenterology, playing an irreplaceable role in the detailed diagnosis and treatment of submucosal lesions of the gastrointestinal tract. An endoscopic ultrasound small probe, also known as a small-probe endoscopic ultrasound, is a medical device that combines a small-probe ultrasound system with an endoscope. This technology uses a small-diameter ultrasound probe (only 2.5 mm in outer diameter) to pass through the S-shaped endoscopic biopsy channel to the surface of the tissue to be examined. Using water as a medium, it clearly displays the layers of the digestive tract wall where the lesion is located, providing diagnostic evidence based on the varying echo densities within the lesion. Small-probe endoscopic ultrasound has a wide range of applications in the diagnosis and treatment of gastrointestinal diseases.

[0003] Currently, endoscopic ultrasound with small probes still has the following shortcomings and limitations: 1. Poor penetration and the requirement for water as a medium. Due to the limited position of the patient during examination, lesions are located high up, making visualization difficult due to difficulty retaining water, thus increasing the difficulty of examination. 2. Frequent water injection during the examination can easily increase the risk of aspiration, leading to aspiration pneumonia or asphyxiation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide an endoscopic ultrasonic small probe water bladder catheter.

[0005] The present invention provides an endoscopic ultrasonic probe water bladder catheter, which is implemented by the following technical solution. The catheter comprises a water bladder having an elliptical water bladder at its distal end. The water bladder is Y-shaped at its front end. The ultrasonic probe is inserted through one opening of the Y-shape. The ultrasonic probe's super energy converter passes through the lumen of the water bladder catheter and reaches the water bladder. The other opening of the Y-shape is a water injection end, which is connected to an upper spiral interface, which is connected to a lower spiral interface via a valve. The lower spiral interface is connected to a syringe. The water injection end is connected to an inner cavity provided within the lumen of the water bladder catheter, and water is injected into the water bladder through the inner cavity.

[0006] The total length of the small probe water bladder catheter is 1650 mm.

[0007] The outer diameter of the lumen of the small probe water balloon catheter is 3.0 mm.

[0008] The outer diameter of the Y-shaped ultrasonic probe insertion section at the front end of the catheter is 2.6 mm, the outer diameter of the lumen of the water injection end at the front end of the water bladder catheter is 2 mm, and the inner lumen of the water injection end at the front end of the catheter is 0.4 mm. After water is injected, the length of the water bladder part is 30 mm and the width is 10 mm. The syringe is a 5 ml syringe and contains 5 ml of sterile water for injection.

[0009] The endoscopic ultrasonic probe bladder catheter is made of medical plastic, and its bladder is made of medical plastic or rubber.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. When using a small probe for ultrasound examination, the small probe is inserted into the water bladder catheter and the water bladder is inflated with one end of the syringe. The small probe is rotated in the water bladder environment to visualize the image, without the need to inject a large amount of water into the stomach or intestinal cavity through the endoscope.

[0011] 2. Due to the large capacity of the gastric cavity, a large amount of water needs to be injected into the gastric cavity to cover the examination area, which can easily cause the patient to have aspiration in the respiratory tract. The present invention avoids the need to inject water into the gastric cavity. The catheter is designed with a built-in water bladder, allowing the small ultrasound probe to pass through the catheter and be inserted into the built-in water bladder, providing a medium for the small ultrasound probe to be visualized.

[0012] 3. After water is injected into the gastric cavity through the endoscope, the water will automatically flow downward to the lower part. Even after a large amount of water is injected, the lesion parts at high positions, such as the esophagus, gastric fundus, cardia, pylorus, etc., are difficult to be immersed in water, which increases the difficulty of inspection. The present invention solves this problem, reduces the difficulty of inspection, and saves inspection time. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0014] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention, and the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0015] like Figure 1 As shown, the present invention comprises a water bladder catheter 1 with an oval-shaped water bladder 2 at its distal end. The water bladder is Y-shaped at its front end. An ultrasonic probe 3 is inserted through one opening of the Y-shaped structure. The ultrasonic probe's superconductor 9 passes through the lumen I of the water bladder catheter and enters the water bladder 2. The other opening of the Y-shaped structure serves as a water injection port 4. This port is connected to an upper spiral interface 7, which is connected to a lower spiral interface 8 via a valve 5. This lower spiral interface 8 is connected to a syringe 6. The injection port 4 is connected to an inner cavity II within the lumen of the water bladder catheter. Water is injected into the water bladder through inner cavity II. After water injection, the water bladder is filled. The upper spiral interface 7 is closed, and the valve 5 is closed. The water bladder remains unchanged, allowing for ultrasound imaging. The water bladder catheter is made of medical plastic, and the water bladder is made of medical plastic or rubber.

[0016] The preferred solution of this embodiment is that the total length of the small probe water bladder catheter 1 is 1650mm, the length of the ultrasonic small probe is 2050mm, the front end of the ultrasonic small probe can be inserted into the front end 3 of the water bladder catheter, and its end is connected to the ultrasonic host, leaving 400mm.

[0017] In a preferred embodiment of this embodiment, the outer diameter of the lumen of the endoscopic ultrasound probe water bladder catheter is 3.0 mm; the outer diameter of the Y-shaped ultrasound probe insertion portion at the front end of the catheter is 2.6 mm, and the outer diameter of the ultrasound probe is 2.5 mm. The front end of the ultrasound probe can be smoothly inserted into the front end 3 of the water bladder catheter. The diameter of the biopsy channel of the gastroscopic therapeutic scope is 3.2 mm, and the diameter of the biopsy channel of the colonoscopy therapeutic scope is 3.7 mm-3.8 mm. Therefore, the water bladder catheter can freely enter and exit the biopsy channel.

[0018] The preferred solution of this embodiment is that the water bladder is 30 mm long and 10 mm wide after being filled with water, and the super energy converter of the ultrasonic probe is 20 mm long and 2.5 mm wide. Therefore, the super energy converter of the ultrasonic probe can be placed entirely in the water bladder.

[0019] The preferred solution of this embodiment is that the outer diameter of the water injection end of the water bladder catheter is 2mm, and the end of the water injection end is connected to a 5ml syringe through an S-spiral interface. The syringe contains 5ml of sterile water for injection, so water can be injected into the water bladder until the water bladder is completely filled.

[0020] The procedure is as follows: Before using the ultrasound probe, insert the ultrasound probe from the front end of the water bladder catheter into the water bladder catheter 1. Then, insert the probe-inserted water bladder catheter into the endoscopic biopsy channel. The water bladder catheter is advanced until it is close to the examination site. The ultrasound probe is advanced until the super-energy converter of the probe is placed within the water bladder 2. The water injection end 4 is connected to the upper spiral interface 7, which is connected to the lower spiral interface 8 via valve 5. The lower spiral interface 8 is connected to the syringe 6. The water injection end 4 is connected to the lumen within the lumen of the water bladder catheter. Water is injected into the water bladder through the lumen. The syringe is pushed to fill the water bladder. Once the water bladder is full, tighten the spiral interface 7 and close the valve 5 to maintain the desired size and keep it fixed. Ultrasound is then turned on, allowing the super-energy converter at the front end of the ultrasound probe to operate within the water bladder. The image of the examination site is then developed using the water bladder as a medium. This prevents the risk of aspiration from the patient's respiratory tract due to large amounts of water injected into the stomach cavity, thus preventing aspiration pneumonia and suffocation. Even for high-positioned lesions that are difficult to store water, the water bladder acts as a medium, allowing for clearer images, reducing operational difficulty and saving time. After the procedure is complete, turn off the ultrasound, stop the small probe from rotating, and remove the small ultrasound probe from the catheter. Open the valve 5 at the front end of the syringe to pump the water from the water bladder back into the syringe 6, then re-lock the valve. Once the water bladder is emptied and deflated, remove the catheter from the biopsy channel, completing the procedure.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
