Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] Referring to Figure 1, an embodiment of this application provides an endoscope tip 100, which can achieve a small-sized tip 110 to meet medical observation needs and reduce patient discomfort.

[0038] Specifically, the endoscope tip 100 includes a tip 110, an imaging module 120, and a serpentine frame 130. The tip 110 has a certain degree of rigidity to facilitate insertion into human organs under external force, and its smooth surface reduces friction during movement. The imaging module 120 is fixed to the tip 110, with its image-acquiring end exposed on the outside of the tip 110 to acquire images as it follows the tip 110's movement. One end of the serpentine frame 130 is fixedly connected to the tip 110 and has a certain degree of flexibility, allowing it to bend as needed during observation.

[0039] Furthermore, both the tip 110 and the snake bone 130 are cylindrical structures, and both the tip 110 and the snake bone 130 have through channels inside, with the imaging module 120 sequentially inserted into the through channels of the tip 110 and the snake bone 130.

[0040] Referring again to Figure 2, exemplarily, the tip 110 includes a support 111 and a glue layer 112. The support 111 has a through cavity, and the glue layer 112 fills the through cavity of the support 111 and is exposed at one end of the support 111. The outer diameter of the end of the support 111 away from the glue layer 112 is the same as the outer diameter of the glue layer 112. The imaging module 120 is covered by the glue layer 112, and the image-taking end of the imaging module 120 is exposed on the outside of the glue layer 112. The snake bone 130 is connected to the end of the support 111 away from the glue layer 112, and the outer diameters of the support 111, the glue layer 112, and the snake bone 130 are all less than 7.5 Fr.

[0041] Specifically, the bracket 111 is made of SUS stainless steel to provide good support strength and corrosion resistance, meeting the operational requirements of the tip 110. The adhesive layer 112 ensures that the tip 110 maintains a certain strength.

[0042] During the production process, the imaging module 120 is placed into the bracket 111, and then a mold is fitted onto the outside of the bracket 111. A dispensing hole is provided on the outside of the mold, and glue is injected into the dispensing hole using a glue injection device to form a glue layer 112 on the outside of the bracket 111. In this way, by using glue injection, only the size of the mold needs to be adjusted to produce the corresponding small-sized tip 110, thereby improving the situation where, due to wall thickness limitations, the outer diameter of the tip 110 cannot be less than 7.5Fr when using plastic molding.

[0043] Referring again to Figure 3, in some embodiments, the support 111 includes an annular base 1111 and at least two uprights 1112 disposed on the base 1111. The at least two uprights 1112 are spaced apart at one end of the base 1111 near the adhesive layer 112 and form a through cavity with the base 1111. At least a portion of the surface of the uprights 1112 is covered by the adhesive layer 112. The outer diameter of the base 1111 is the same as the outer diameter of the adhesive layer 112. The snake-shaped support 130 is connected to the end of the base 1111 away from the adhesive layer 112. The overall structure of the support 111 is compact and has higher strength.

[0044] In some embodiments, the imaging module 120 includes a camera 121 and a light-emitting element 122, with the light-emitting element 122 disposed on the side of the camera 121. At least a portion of the surface of the camera 121 and at least a portion of the surface of the light-emitting element 122 are covered by a glue layer 112, and the image-capturing end of the camera 121 is exposed on the outside of the glue layer 112.

[0045] Specifically, the camera 121 may include a circuit board and a lens integrated on the circuit board for image acquisition. The light-emitting element 122 may be an LED light and is disposed on the side of the camera 121. During the observation operation of the lens, the light-emitting element 122 can provide illumination to improve the image acquisition clarity of the lens.

[0046] Understandably, the camera component 121 and the light-emitting component 122 are also connected to conductive wires for operation after being connected to a power source. The camera component 121 and the light-emitting component 122 are fixed to the tip 110 under the coverage of the glue layer 112, and the conductive wires are run through the snake bone 130 and can bend with the snake bone 130.

[0047] Furthermore, there are two light-emitting elements 122, and the two light-emitting elements 122 are arranged opposite each other on both sides of the lens to improve the shooting clarity of the camera 121.

[0048] In one embodiment, both the snake skeleton 130 and the support 111 are made of SUS stainless steel to ensure the operational performance of the snake skeleton 130. Preferably, the SUS stainless steel material is SUS304 stainless steel.

[0049] Furthermore, the snake bone 130 and the bracket 111 are connected by laser welding, which ensures the strength of the connection between the snake bone 130 and the bracket 111.

[0050] Referring further to Figure 4, the snake skeleton 130 includes multiple segments 131, with adjacent segments 131 rotatably connected. Specifically, the snake skeleton 130 achieves bending in different directions through the interlocking structure of the multiple segments 131 to adapt to different observation paths.

[0051] In some embodiments, the bending diameter of the snake bone 130 is 1.5cm-3.5cm.

[0052] For example, the bending diameter of the snake bone 130 can be 1.5cm, 1.6cm, 1.7cm, 1.8cm, 1.9cm, 2.0cm, 2.1cm, 2.2cm, 2.3cm, 2.4cm, 2.5cm, 2.6cm, 2.7cm, 2.8cm, 2.9cm, 3.0cm, 3.1cm, 3.2cm, 3.3cm, 3.4cm, 3.5cm, etc., and can be reasonably selected according to actual needs to meet different work path curvatures.

[0053] In some embodiments, the total length of the tip 110 and the snake bone 130 is 3.5cm-8cm.

[0054] For example, the total length of the tip 110 and the snake bone 130 can be 3.5cm, 4cm, 4.5cm, 5cm, 5.5cm, 6cm, 6.5cm, 7cm, 7.5cm, 8cm, etc., and can be reasonably selected according to actual needs to meet different work path lengths.

[0055] Referring again to Figure 5, in some embodiments, the endoscope tip 100 further includes an instrument tube 140, with the tip 110 and the snake bone 130 covering one end of the instrument tube 140.

[0056] Specifically, during the glue injection process of the tip 110, a channel for installing the instrument tubing 140 can be reserved, or the instrument tubing 140 and the support 111 can be glued and fixed simultaneously during the glue injection process. With the instrument tubing 140 in place, when the tip 110 reaches the designated location, medical personnel can insert the diagnostic and treatment accessories through the instrument tubing 140 as needed to perform corresponding medical and nursing procedures, such as sampling, lithotripsy, and medication delivery.

[0057] Referring again to Figure 6, an embodiment of this application also provides a disposable electronic ureteropelvic endoscope catheter 1000, including the endoscope tip 100 and insertion tube 200 in any of the above embodiments, wherein the insertion tube 200 is connected to the end of the snake bone 130 away from the support 111.

[0058] Specifically, the disposable electronic ureteropelvic endoscope catheter 1000 provided in this application can be used for minimally invasive urological surgery to diagnose and treat diseases of the upper urinary tract (such as the ureter and renal pelvis). During treatment, the endoscope tip 100 is inserted into the human organ by applying force to one end of the insertion tube 200.

[0059] This embodiment has the endoscope tip 100 of any of the above embodiments, and therefore has all the beneficial effects of the endoscope tip 100 of any of the above embodiments, which will not be described in detail here.

[0060] In some embodiments, the outer diameters of the support 111, the adhesive layer 112, the snake bone 130, and the insertion tube 200 are all less than 6.3 Fr.

[0061] For example, to facilitate the diagnosis of the renal pelvis, the outer diameter of the disposable electronic ureteropelvic endoscope catheter 1000 is set to 6.3Fr, thereby facilitating the entry of the disposable electronic ureteropelvic endoscope catheter 1000 into the renal pelvis.

[0062] In some embodiments, the total length of the tip 110, the snake bone 130, and the insertion tube 200 is 30cm-70cm.

[0063] For example, the total length of the tip 110, the snake bone 130 and the insertion tube 200 can be 30cm, 35cm, 40cm, 45cm, 50cm, 55cm, 60cm, 65cm, 70cm, etc., and can be reasonably selected according to actual needs to meet different operating path lengths.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
