Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water storage sacs, in particular to a water storage sac for a small probe ultrasonic endoscope. Background Technique
[0002] In recent years, with the rapid development of digestive endoscopy technology, various intraluminal protuberant, flat, and depressed lesions in the digestive tract and respiratory tract have been discovered. To determine the nature and depth of the lesions, ultrasonic endoscopy technology has been widely used, providing a more scientific basis for the formulation of treatment plans. However, there is an air gap between the ultrasonic endoscope instrument and the mucosa, and ultrasonic waves are poorly transmitted and absorbed in the air, making it impossible to obtain an effective reflected image. Therefore, clean water is required as a medium to obtain a clear image.
[0003] However, during the doctor's diagnosis and treatment process, it is often difficult for patients to store the water medium, there is interference from secretions, and they are intolerant of ordinary ultrasonic endoscopy examinations, resulting in the inability to effectively complete the examination and even the risk of suffocation. With the development of ultrasonic endoscopy technology, the water storage sac (transparent cap) has emerged, solving some problems in ultrasonic endoscopy operation and diagnosis.
[0004] Currently, when the water storage sac is used, it is directly sleeved on the top end of the endoscope. Since the endoscope will touch the human tissue when it penetrates deep into the human body, when the endoscope is withdrawn, the water storage sac may fall off due to the contact with the human tissue, which may involve the safety of the patient.
[0005] Therefore, in view of the above problems, we propose a water storage sac for a small probe ultrasonic endoscope. Content of the Utility Model

Two groups of fixing structures are arranged inside the first connecting sleeve, a sliding extrusion structure is arranged on the second connecting sleeve, and a water sac is fixedly sleeved on the outer wall of the first connecting sleeve.
[0008] As a further description of the utility model: The fixing structure includes a connecting block, a connecting groove for the connecting block to slide is opened on the pipe wall of the first connecting sleeve, one end of the connecting block is fixedly installed with a pressing block, one end of the pressing block close to the second connecting sleeve is fixedly installed with a guiding block, and the cross-section of the guiding block is triangular.
[0009] As a further description of the present utility model: One end of the connecting block away from the pressing block is fixedly installed with a fixing plate, the fixing plate is designed in a semicircular shape, and a plurality of groups of equally spaced convex points are fixedly installed on the side walls of the two fixing plates close to each other.
[0010] As a further description of the present utility model: The sliding extrusion structure includes a first sliding sleeve, a second sliding sleeve is fixedly installed inside the first sliding sleeve, the first sliding sleeve is made of medical silicone material, and the second sliding sleeve is made of hard plastic material.
[0011] As a further description of the present utility model: A first limiting ring and a second limiting ring are respectively fixedly installed at both ends inside the second sliding sleeve. The inner diameter dimension of the first limiting ring matches the outer diameter dimension of the second connecting sleeve. The inner diameter dimension of the second limiting ring matches the outer diameter dimension of the first connecting sleeve. One end of the second limiting ring away from the first limiting ring is funnel-shaped.
[0012] As a further description of the present utility model: The outer wall of the second connecting sleeve is coated with a medical hydrophilic coating, and the water sac is made of natural latex material.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] By designing a fixing structure and a sliding extrusion structure on a water storage sac for a small probe ultrasonic endoscope, during use, the endoscope probe is inserted into the second connecting sleeve along the first connecting sleeve, and then the second sliding sleeve is slid along the direction of the first connecting sleeve, so that the second sliding sleeve is sleeved on the outer wall of the first connecting sleeve and presses the pressing block, driving the two fixing plates to approach each other to fix the first connecting sleeve and the endoscope probe, and the convex points can increase the connection strength between the first connecting sleeve and the endoscope probe, reducing the situation that when the endoscope is retrieved, due to a certain amount of rubbing against human tissues, the water sac is left in the patient's body, thereby causing damage to the patient.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.
[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a water storage sac for a small probe ultrasonic endoscope, including a first connecting sleeve 1, a second connecting sleeve 2 is fixedly installed at the bottom of the first connecting sleeve 1, wherein the outer diameter of the first connecting sleeve 1 is larger than the outer diameter of the second connecting sleeve 2, and the inner diameter is the same. Two groups of fixing structures 3 are arranged inside the first connecting sleeve 1, a sliding extrusion structure 4 is arranged on the second connecting sleeve 2, and a water sac 5 is fixedly sleeved on the outer wall of the first connecting sleeve 1.
[0022] In this embodiment: the fixing structure 3 includes a connecting block 301, a connecting groove for the connecting block 301 to slide is opened on the pipe wall of the first connecting sleeve 1, a pressing block 302 is fixedly installed at one end of the connecting block 301, a guiding block 303 is fixedly installed at one end of the pressing block 302 close to the second connecting sleeve 2, and the cross section of the guiding block 303 is triangular.
[0023] During specific use: the guiding block 303 can be used in cooperation with the second limiting ring 404 to facilitate the sliding of the first sliding sleeve 401 and the second sliding sleeve 402 from the second connecting sleeve 2 to the first connecting sleeve 1 to squeeze the pressing block 302.
[0024] In this embodiment: a fixing plate 304 is fixedly installed at one end of the connecting block 301 away from the pressing block 302, the fixing plate 304 is semicircular in design, and a plurality of groups of equally spaced convex points 305 are fixedly installed on the side walls of the two fixing plates 304 close to each other.
[0025] During specific use: the two fixing plates 304 can clamp and fix the endoscope, and the connection strength between the fixing plate 304 and the endoscope is enhanced through the convex points 305.
[0026] In this embodiment: The sliding extrusion structure 4 includes a first sliding sleeve 401, and a second sliding sleeve 402 is fixedly installed inside the first sliding sleeve 401. The first sliding sleeve 401 is made of medical silicone, while the second sliding sleeve 402 is made of hard plastic.
[0027] During specific use: When the surface of the second sliding sleeve 402 made of hard plastic is extruded by the pressing block 302, it will deform, resulting in an unstable fixation between the first connecting sleeve 1 and the endoscope.
[0028] In this embodiment: A first limiting ring 403 and a second limiting ring 404 are respectively fixedly installed at both ends inside the second sliding sleeve 402. The inner diameter size of the first limiting ring 403 matches the outer diameter size of the second connecting sleeve 2, and the inner diameter size of the second limiting ring 404 matches the outer diameter size of the first connecting sleeve 1. One end of the second limiting ring 404 away from the first limiting ring 403 is funnel-shaped.
[0029] During specific use: The first limiting ring 403 prevents the first sliding sleeve 401 and the second sliding sleeve 402 from detaching during the sliding process towards the first connecting sleeve 1, while the second limiting ring 404 can prevent the first sliding sleeve 401 and the second sliding sleeve 402 from returning to the second connecting sleeve 2. The funnel-shaped second limiting ring 404 facilitates the sliding of the first sliding sleeve 401 and the second sliding sleeve 402 from the second connecting sleeve 2 to the first connecting sleeve 1.
[0030] In this embodiment: The outer wall of the second connecting sleeve 2 is coated with a medical hydrophilic coating, and the water sac 5 is made of natural latex.
[0031] During specific use: The medical hydrophilic coating can lock water on the outer wall of the digestive endoscope transparent cap to form a water film, which helps prevent blood and mucus from adhering to the surface of the transparent cap and effectively avoids affecting the transparency of the transparent cap.
[0032] Working principle: During use, insert the endoscope probe along the first connecting sleeve 1 into the second connecting sleeve 2, and then slide the first sliding sleeve 401 and the second sliding sleeve 402 along the direction of the first connecting sleeve 1 so that the first sliding sleeve 401 and the second sliding sleeve 402 are sleeved on the outer wall of the first connecting sleeve 1. At this time, the second sliding sleeve 402 will squeeze the pressing block 302, driving the two groups of fixing plates 304 to approach each other to fix the first connecting sleeve 1 and the endoscope probe, and the convex points 305 can increase the connection strength between the first connecting sleeve 1 and the endoscope probe, reducing the situation that when the endoscope is retrieved, due to a certain degree of rubbing against human tissues, the water sac 5 is left in the patient's body, thereby causing damage to the patient.
