Description

Technical Field

[0001] This utility model relates to the field of esophageal inlet endoscope technology, and in particular to an esophageal inlet endoscope. Background Technology

[0002] In clinical endoscopic examinations, especially esophageal examinations, physicians often rely on auxiliary instruments such as esophagoscopes and laryngoscopes to aid observation and manipulation. However, existing esophagoscopes have relatively simple structures, often lacking a good interface for integration with endoscopic systems. Their rigid design also leads to problems such as limited operating space, significant patient discomfort, obstructed field of vision, and low efficiency in foreign body removal during insertion. Furthermore, traditional esophagoscopes cannot sense and provide real-time feedback on physiological parameters at the esophageal inlet, hindering high-precision and intelligent clinical diagnostic support. While some products on the market offer inlet endoscopes for clinical diagnostic support, they still suffer from significant technical limitations and urgently require technological optimization.

[0003] For example, patent number CN210520944U describes an esophageal inlet endoscope, comprising a cylindrical, hollow endoscope body. One side of the endoscope body is inclined and connected to a hollow endoscope tube. The spatial angle between the endoscope tube and the endoscope body is 3°-30°. The inlet end of the endoscope tube and the inlet end of the endoscope body are located on the same side. A handle is also connected to the upper end of the inlet end of the endoscope body. The inlet end of the endoscope tube is connected to a stepped-diameter interface. In this invention, an endoscope tube is provided on one side of the endoscope body. The size of the endoscope tube matches the working end of the endoscope of the endoscopic imaging system. In use, the working end of the endoscope of the endoscopic imaging system extends into the endoscope tube. The tip of the working end is located at the front of the endoscope body, communicating with the endoscope tube. The endoscope tube and the working end of the endoscope are fully aligned, providing a good field of vision during esophageal examination. It is ideal for removing foreign objects and conducting examinations, is convenient to use, has a simple structure, and is easy to promote and apply. While the above-mentioned technical solutions facilitate the examination of the esophagus and maintain a good field of vision, they still have significant problems in use. For example, when holding the handle, the cylindrical structure of the handle can easily cause it to rotate between the handle and the hand, making it inconvenient to hold. Furthermore, it is impossible to determine the distance between the end of the endoscope and the incisors, as well as the depth of insertion of the endoscope. Additionally, it is impossible to know physiological parameters such as temperature and pH value in the esophagus to assist in the operation.

[0004] To address the aforementioned issues, this invention provides a fully functional esophageal inlet endoscope, featuring an endoscope tube that can be precisely docked with existing endoscopic imaging systems. The endoscope tube and the endoscope body are angled, which effectively improves the observation range and operational flexibility. Additionally, external graduation lines facilitate clinicians in determining the insertion depth of the endoscope. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an esophageal inlet endoscope.

[0006] The purpose of this utility model is achieved as follows: An esophageal inlet endoscope includes an endoscope body, which is a cylindrical hollow structure. An endoscope tube is inclinedly connected to one side of the endoscope body. The endoscope tube is also a cylindrical hollow structure. The spatial angle between the endoscope tube and the endoscope body is 5°. The inlet end of the endoscope tube and the inlet end of the endoscope body are located on the same side. A handle is connected to the upper end of the inlet end of the endoscope body. The inlet end of the endoscope tube is connected to an interface with a stepped diameter. The handle is an arc-shaped structure. The left end of the endoscope body is inclined downward. Scale lines are provided on the upper part of the outer surface of the endoscope body. A sensor is provided on the upper left part of the inner side of the endoscope body.

[0007] Furthermore, the graduation lines are distributed starting from the left end of the mirror body.

[0008] Furthermore, the diameter of the interface decreases in a stepped manner towards the inlet end of the endoscope tube, and the connection position between the outlet end of the endoscope tube and the endoscope body extends from the middle of the endoscope body towards the outlet end of the endoscope body.

[0009] Furthermore, the endoscope tube opens at a point 0.5 cm from the end of the endoscope body.

[0010] Furthermore, the endoscope tube and the central axis of the endoscope body are on the same horizontal plane.

[0011] Furthermore, the outer surface of the mirror is provided with a smoothing layer, which is a silicone coating. Because silicone has good lubricity and biocompatibility, it can make the surface smoother and cause less damage to human tissue.

[0012] Furthermore, the outer end of the handle is provided with a connector, and the outer side of the connector is provided with a notch. The notch is located on the handle in the direction of the right end of the lens body. The depth of the notch is 10mm and the width of the notch is 10mm.

[0013] In use, this invention features an endoscope tube on one side of the endoscope body, the size of which matches the working end of the endoscope in the endoscopic imaging system. During use, the working end of the endoscope extends into the endoscope tube, with the front end of the working end of the endoscope tube positioned at the front of the endoscope body, connecting with the endoscope tube. This ensures complete docking between the endoscope tube and the working end of the endoscope, providing excellent visibility during esophageal examinations. It is ideal for foreign body removal and examination, convenient to use, and has a simple structure, facilitating widespread application. Compared to existing technologies, this invention features an arc-shaped handle, making it easier to hold the device. The arc-shaped handle increases the distance between the middle of the handle and the front of the endoscope body, providing a wider operating space in front of the handle compared to a straight handle. Furthermore, the arc angle of the handle increases grip strength, preventing rotation of the handle relative to the hand. A notch is provided at the connector to facilitate the use of a fixed support frame (the fixed support frame is for fixing this device and is existing technology, so further technical details are omitted).

[0014] The scope is equipped with graduations to determine the distance between the end of the scope (the graduations are calculated from the longest side of the inclined surface at the end of the scope) and the incisors, as well as the insertion depth of the scope. The end of the scope has an inclined surface that is longer at the top and shorter at the bottom. The left side of the scope is inclined to connect to the hollow endoscope tube inside. The endoscope tube and the scope body are on the same horizontal plane. The end of the endoscope tube opens 0.5 cm from the end of the scope – 0.5 cm from the shortest side of the inclined surface at the end of the scope.

[0015] A sensor (micro-sensor chip) is embedded in the inner wall of the longest side tube on the inclined surface at the tail end of the endoscope. (The micro-sensor chip is embedded in the endoscope body, the surface of the endoscope body is smooth, and there are micro-holes for sensing.) It can monitor physiological parameters such as pressure, temperature, and pH value at the esophageal inlet in real time (different types of sensors can be set as needed to measure different parameters), and can also sense physiological parameters such as temperature or pH value of foreign objects in front. The above sensors are existing technologies and will not be described in detail. It is sufficient that they can be implemented in the application of this application.

[0016] This utility model is used in conjunction with an endoscopic imaging system, which includes an OTC processing system, an optical imaging system, and a cold light source host. The tip of the endoscope working end of the endoscopic imaging system is embedded with an OTC probe module, and the OTC probe module contains an OTC imaging component. In use, the working end of the endoscope of the endoscopic imaging system extends into the endoscope tube, and the interface locks the tail end of the working end. The tip of the working end is located at the front of the endoscope body, communicating with the endoscope tube. The endoscope tube and the working end are fully connected, providing a good field of vision during examination. Since 60% to 75% of esophageal foreign bodies are lodged at the first constriction, i.e., the esophageal inlet, and the first constriction is difficult to access in actual clinical practice, leading to frequent accidents, the connection between the endoscope tube and the working end combines the shortness of the esophagoscopy with the length of the laryngoscope, making it ideal for foreign body removal and examination. In addition, this esophageal inlet endoscope can also be used independently with a nasal endoscope. Combined with the existing nasal endoscope imaging system, it forms a perfect combination, achieving the purpose of convenient observation and operation. Therefore, this utility model has the advantages of being able to connect with the imaging system, being easy to use, and having a simple structure, making it easy to promote and use.

[0017] Beneficial effects: This utility model has the following technical effects when used:

[0018] 1. The scale lines can be set to determine the distance between the end of the lens body (the scale is calculated from the longest and shortest inclined surface at the end of the lens body) and the incisors, as well as the insertion depth of the lens body.

[0019] 2. A sensor (micro-sensor chip) is embedded in the inner wall of the longest side tube on the inclined surface at the tail end of the endoscope. (The micro-sensor chip is embedded in the endoscope body, the surface of the endoscope body is smooth, and there are micro-holes for sensing.) It can monitor physiological parameters such as pressure, temperature, and pH value at the entrance of the esophagus in real time (different types of sensors can be set as needed to measure different parameters), and can also sense physiological parameters such as temperature or pH value of foreign objects in front.

[0020] 3. The device is equipped with an arc-shaped handle, which makes it easier to hold the device. The arc-shaped handle increases the distance between the middle of the handle and the front of the lens. Compared with a straight handle, the operating space in front of the handle is wider during operation. When holding the handle, the arc angle increases the grip strength and prevents the handle from rotating relative to the hand. Attached Figure Description

[0026] Example 1, such as Figure 1-3 As shown, the purpose of this utility model is achieved as follows: An esophageal inlet endoscope includes an endoscope body 1, which is a cylindrical hollow structure. An endoscope tube 2 is obliquely connected to one side of the endoscope body 1. The endoscope tube 2 is also a cylindrical hollow structure. The spatial angle between the endoscope tube 2 and the endoscope body 1 is 5° (this angle reduces patient discomfort and friction and irritation during insertion, making it suitable for patients of different ages and physical conditions, especially those with abnormal physiological structures such as excessively long maxillary incisors or endodontic malformations). The inlet end of the endoscope tube 2 is located on the same side as the inlet end of the endoscope body 1. A handle 3 is connected to the upper end of the inlet end of the endoscope body 1. The inlet end of the endoscope tube 2 is connected to a stepped-diameter interface. The handle 3 is an arc-shaped structure. The left end of the endoscope body 1 is inclined downwards. A scale line 6 is provided on the upper part of the outer surface of the endoscope body 1. A sensor 7 is provided on the upper left part of the inner surface of the endoscope body 1. The length of the endoscope body 1 is mainly divided into 15cm, 25cm, and 35cm, with the medium size generally being sufficient. The endoscope body 1 is made of polyetheretherketone (PEEK), a new type of high-performance plastic material. Compared with a general esophageal endoscope, the weight of endoscope body 1 is only 1 / 5 of that of a typical endoscope. It has excellent high-temperature resistance, corrosion resistance, as well as excellent mechanical properties, wear resistance, and light weight, and can be used for a long time in high-temperature and chemically corrosive environments.

[0027] The graduation lines 6 begin to appear from the left end of the endoscope body 1. The diameter of the tube, facing the inlet end of the endoscope tube 2, decreases in a stepped manner. The connection point between the outlet end of the endoscope tube 2 and the endoscope body 1 extends from the middle of the endoscope body 1 towards the outlet end. The tail end of the endoscope tube 2 opens 0.5 cm from the tail end of the endoscope body 1. The central axes of the endoscope tube 2 and the endoscope body 1 are on the same horizontal plane.

[0028] The outer surface of the scope body 1 is provided with a smoothing layer, which is made of silicone. Because silicone has good lubricity and biocompatibility, it can make the surface smoother and cause less damage to human tissue. The outer end of the handle 3 is provided with a connector 4, and the outer side of the connector 4 is provided with a notch 5. The notch 5 is located on the handle 3 on the right side of the scope body 1. The depth of the notch 5 is 10mm and the width of the notch 5 is 10mm.

[0029] When in use, this utility model has an endoscope tube 2 on one side of the endoscope body 1. The size of the endoscope tube 2 matches the working end of the endoscope of the endoscope imaging system. When in use, the working end of the endoscope of the endoscope imaging system extends into the endoscope tube 2. The front end of the working end of the endoscope tube 2 is located at the front of the endoscope body 1 and communicates with the endoscope tube 2. The endoscope tube 2 and the working end of the endoscope are fully connected, providing a good field of vision during esophageal examination. It is just right for foreign body removal and examination, convenient to use, simple in structure, and easy to promote and apply. Compared to the prior art, this application features an arc-shaped handle 3, which makes it easier to hold the device. The arc-shaped handle 3 also increases the distance between the middle of the handle 3 and the front end of the lens body 1. Compared to a straight handle 3, the operating space at the front of the handle 3 is wider during operation. Furthermore, the arc-shaped handle 3 has a certain arc angle, which increases the grip strength and prevents the handle 3 from rotating relative to the hand. A notch 5 is provided at the connector 4 to facilitate the use of a fixed support frame (the fixed support frame is the support frame for fixing this device, which is prior art and will not be described in detail).

[0030] The scale line 6 allows for the determination of the distance between the end of the endoscope body 1 (the scale is calculated from the shortest side of the inclined surface at the end of the endoscope body 1) and the incisors, as well as the insertion depth of the endoscope body 1. The end of the endoscope body 1 has an inclined surface that is longer at the top and shorter at the bottom. The left side of the endoscope body 1 is inclined to connect to the hollow endoscope tube 2 inside. The endoscope tube 2 and the body of the endoscope body 1 are on the same horizontal plane. The end of the endoscope tube 2 opens 0.5cm from the end of the endoscope body 1—0.5cm from the shortest side of the inclined surface at the end of the endoscope body 1.

[0031] A sensor 7 (a micro-sensor 7 chip) is embedded in the inner wall of the longest side tube on the inclined surface at the tail end of the endoscope 1. (The micro-sensor 7 chip is embedded in the endoscope 1, and the surface of the endoscope 1 is smooth with micro-holes for sensing.) It can monitor physiological parameters such as pressure, temperature, and pH value at the esophageal inlet in real time (different types of sensors 7 can be set as needed to measure different parameters), and can also sense physiological parameters such as temperature or pH value of foreign objects in front. The above sensor 7 is prior art and will not be described in detail. It is sufficient that it can be implemented in the application of this application.

[0032] This utility model is used in conjunction with an endoscopic imaging system, which includes an OTC processing system, an optical imaging system, and a cold light source host. The tip of the endoscope working end of the endoscopic imaging system is embedded with an OTC probe module, and the OTC probe module contains an OTC imaging component. In use, the working end of the endoscope of the endoscopic imaging system extends into the endoscope tube 2, and the interface locks the tail end of the working end. The tip of the working end is located at the front of the endoscope body 1, communicating with the endoscope tube 2. The endoscope tube 2 and the working end of the endoscope are fully connected, providing a good field of vision during examination. Since 60% to 75% of esophageal foreign bodies are lodged at the first constriction, i.e., the esophageal inlet, and the first constriction is difficult to operate in actual clinical practice, resulting in frequent accidents, the connection between the endoscope tube 2 and the working end of the endoscope combines the shortness of the esophageal endoscope with the length of the laryngoscope, making it ideal for foreign body removal and examination. In addition, this esophageal inlet endoscope can also be used independently with a nasal endoscope. Combined with the existing nasal endoscope imaging system, it forms a perfect combination, achieving the purpose of convenient observation and operation. Therefore, this utility model has the advantages of being able to connect with the imaging system, being easy to use, and having a simple structure, making it easy to promote and use.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
