Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to an endoscope tip and an endoscope. Background Technology

[0003] Currently, traditional endoscope tips are generally cylindrical in shape. During clinical cannulation, the tip is prone to scraping and rubbing against the inner wall of the patient's organ tissue, increasing resistance and making cannulation difficult. Furthermore, when encountering organs with polyps (making the patient's access narrower), the endoscope cannot conduct further in-depth examination, and in severe cases, it may even scratch the patient's organ tissue. Utility Model Content

[0008] The end face is connected to both the first conical surface and the at least one inclined surface.
[0009] In an optional embodiment, there are two inclined surfaces, which are arranged opposite to each other and are respectively connected to the two ends of the first conical surface.

[0014] In an optional implementation, the size of the second conical surface is larger than the size of the first conical surface.
[0015] In an optional embodiment, the endoscope tip further includes an illumination assembly disposed on the end face and close to the second conical surface; and / or,
[0016] The endoscope tip also includes a camera assembly, which is disposed on the end face and close to the second conical surface.
[0017] In an optional embodiment, the endoscope tip is further provided with a working channel that extends through the end face and is located close to the first conical surface.
[0018] In an optional embodiment, the junction between the second conical surface and the at least one inclined surface is rounded; and / or,
[0019] The connection between the second conical surface and the end face is rounded.
[0020] Secondly, this utility model provides an endoscope, including a curved portion, a clamping tube, and an endoscope tip as described in any of the foregoing embodiments, wherein the curved portion is connected to the proximal end of the endoscope tip.
[0021] In an optional embodiment, the curved portion includes a snake-like bone, the forceps channel is connected to the proximal end of the endoscope tip and communicates with the working channel of the endoscope tip; the snake-like bone is sleeved on the forceps channel and is connected to the proximal end of the endoscope tip.
[0022] The axis of the forceps tube is spaced apart from the axis of the endoscope tip, and the axis of the snake bone is also spaced apart from the axis of the endoscope tip.
[0023] The beneficial effects of this utility model embodiment include:
[0024] The distal end of the endoscope tip has a circumferential surface and an end face. The circumferential surface includes a first conical surface and at least one inclined surface. The first conical surface is connected to the at least one inclined surface, and the at least one inclined surface is inclined toward the end face. The end face is connected to both the first conical surface and the at least one inclined surface. In other words, the distal end of the endoscope tip has a cone-shaped structure. Specifically, by setting the first conical surface at the distal end of the endoscope tip, a guiding function can be achieved. At the same time, by chamfering the circumferential surface of the tip to form an inclined surface, the overall volume of the distal end of the tip can be reduced. In conjunction with the first conical surface, while providing a guiding effect, the contact area between the tip and the organ tissue is reduced, and the resistance is correspondingly reduced, thereby facilitating cannulation operations and preventing the tip from scratching the organ tissue.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0037] As described in the background section, the conventional endoscope tip is generally cylindrical. During clinical intubation, the tip tends to scrape and rub against the inner wall of the patient's organ tissue, increasing resistance and making intubation difficult. Furthermore, when encountering organs with polyps (where the patient's access becomes narrower), the endoscope cannot conduct further in-depth examinations, and in severe cases, it may even scratch the patient's organ tissue.
[0038] Based on this, please refer to Figures 1-3 The present invention provides an endoscope tip 10 and an endoscope 100, which can effectively improve the aforementioned technical problems. That is, it can reduce the contact area with organs and tissues, facilitate cannulation operations, and prevent the tip from scratching organs and tissues. The endoscope tip 10 and the endoscope 100 will be described in detail below.
[0039] Please refer to Figure 1 , Figure 1 This is a partial structural diagram of the endoscope 100 provided in this embodiment, combined with... Figure 1 The endoscope 100 includes an endoscope tip 10, a curved portion 20, and a forceps channel 30, with the curved portion 20 connected to the proximal end of the endoscope tip 10. It should be noted that, as will be readily apparent to those skilled in the art, the endoscope 100 also includes other components such as an operating section, which will not be described in detail here.
[0040] For details, please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the first view of the endoscope tip 10 provided in this embodiment. Figure 3 This is a structural schematic diagram of the second viewpoint of the endoscope tip 10 provided in this embodiment. (Combined with...) Figure 2 and Figure 3 The distal end of the endoscope tip 10 has a peripheral surface 11 and an end face 12. The peripheral surface 11 includes a first conical surface 111 and at least one inclined surface 112. The first conical surface 111 is connected to at least one inclined surface 112, and the at least one inclined surface 112 is inclined toward the end face 12. The end face 12 is connected to both the first conical surface 111 and at least one inclined surface 112.
[0041] In other words, the distal end of the endoscope tip 10 has a cone-shaped structure. Specifically, by setting a first conical surface 111 at the distal end of the endoscope tip 10, a guiding function can be achieved. At the same time, the peripheral surface 11 of the tip is chamfered to form an inclined surface 112, which reduces the overall volume of the distal end of the tip. In conjunction with the first conical surface 111, while providing a guiding effect, the contact area between the tip and the organ tissue is reduced, and the resistance is correspondingly reduced, thereby facilitating cannulation and preventing the tip from scratching the organ tissue.
[0042] It should be noted that in this embodiment, there are two inclined surfaces 112, which are arranged opposite to each other and are respectively connected to the two ends of the first conical surface 111.
[0043] like Figure 2 As shown, it is understandable that by chamfering the two opposite sides of the endoscope tip 10 to form two inclined surfaces 112, guidance can be provided on both sides simultaneously during cannulation, resulting in better performance. Furthermore, the overall volume of the distal structure of the tip is smaller, and in conjunction with the first conical surface 111, the contact area between the tip and the organ tissue can be further reduced, resulting in less resistance and thus protecting the organ tissue from damage.
[0044] Of course, in other embodiments, the number of inclined surfaces 112 may be one, three or four, and the specific number needs to be determined according to the design requirements of the tip and in combination with the actual clinical situation.
[0045] To further protect organs and tissues from scratches by the tip, in this embodiment, the connection between the first conical surface 111 and at least one inclined surface 112 is rounded. The rounded corners create an arc surface at the connection, which also serves as a guide and better conforms to the organs and tissues, allowing for a smooth transition during operation and thus protecting the organs and tissues from damage.
[0046] Similarly, in this embodiment, the connection between the first conical surface 111 and the end face 12 is rounded; at least one inclined surface 112 is rounded at the connection between it and the end face 12. This further protects organ tissues and prevents them from being scratched by the tip.
[0047] Please continue to combine Figure 2 and Figure 3 The peripheral surface 11 also includes a second conical surface 113, which is connected to at least one inclined surface 112 and is disposed opposite to the first conical surface 111; the end face 12 is connected to the second conical surface 113. Specifically, in this embodiment, the two ends of the second conical surface 113 are also connected to two inclined surfaces 112 respectively.
[0048] It is easy to understand that by setting the second conical surface 113, it can also play a guiding role, and together with the first conical surface 111 and the inclined surface 112, it can further play a role in protecting organs and tissues.
[0049] Furthermore, such as Figure 2 As shown, in this embodiment, the size of the second conical surface 113 is larger than the size of the first conical surface 111. This allows other components of the tip to be conveniently arranged in a portion of the end face 12 near the second conical surface 113.
[0050] Optionally, the endoscope tip 10 also includes an illumination assembly 13, which is disposed on the end face 12 and close to the second conical surface 113.
[0051] Optionally, the endoscope tip 10 also includes a camera assembly 14, which is disposed on the end face 12 and close to the second conical surface 113.
[0052] It should be noted that in this embodiment, there are two lighting components 13, which are spaced apart, and the camera component 14 is located between the two lighting components 13. In this way, while improving the lighting effect, the lighting components 13 and the camera component 14 can be arranged in a concentrated manner, improving the integration effect of the tip, further reducing the size, and satisfying the guiding effect of the tip's conical structure.
[0053] Furthermore, the endoscope tip 10 is also provided with a working channel 15, which extends through the end face 12 and is positioned close to the first conical surface 111. It is easy to understand that the working channel 15 provides operating space for instruments such as biopsy forceps, facilitating the passage of these instruments for corresponding medical procedures. In this embodiment, by positioning the working channel 15 close to the first conical surface 111, the spatial requirements for the coordinated arrangement of the first conical surface 111, the inclined surface 112, and the second conical surface 113 are also met. While providing guidance, this also ensures a reduction in the overall volume of the tip, thereby reducing the contact area with organ tissues during operation, decreasing resistance, and preventing tissue abrasion.
[0054] To further protect organs and tissues from scratches by the tip, in this embodiment, the connection between the second conical surface 113 and at least one inclined surface 112 is rounded. Similarly, the connection between the second conical surface 113 and the end face 12 is also rounded, further protecting organs and tissues from damage.
[0055] Please combine Figures 1-3 Specifically, the curved portion 20 includes a forceps channel 30 and a snake-shaped bone 22. The forceps channel 30 is connected to the proximal end of the endoscope tip 10 and communicates with the working channel 15 of the endoscope tip 10. In other words, biopsy forceps and other instruments pass through the forceps channel 30 and the working channel 15 in sequence to reach the corresponding organ or tissue.
[0056] The snake-shaped bone 22 is fitted onto the forceps tube 30 and is connected to the proximal end of the endoscope tip 10. The snake-shaped bone 22 allows for flexible steering and precise control of the endoscope tip 10 within the body cavity.
[0057] Specifically, the snake bone 22 includes multiple snake bone segments 221 and rivets 222. The multiple snake bone segments 221 are arranged sequentially along the axial direction of the endoscope tip 10, and adjacent snake bone segments 221 are connected and fixed by rivets 222.
[0058] It should be noted that, as will be readily apparent to those skilled in the art, both the lighting assembly 13 and the camera assembly 14 are connected to the control components on the operating part of the endoscope 100 via wires. The wires and the forceps tube 30 are arranged parallel to each other within the snake bone 22, which will not be elaborated upon in this embodiment. In this embodiment, the axis of the forceps tube 30 is spaced apart from the axis of the endoscope tip 10, and the axis of the snake bone 22 is also spaced apart from the axis of the endoscope tip 10.
[0059] like Figure 1 As shown, the axis of the endoscope tip 10 is axis A, the axis of the clamp tube 30 is axis B, and the axis of the snake bone 22 is axis C. By setting the axis B of the clamp tube 30 and the axis A of the endoscope tip 10 at intervals, it is beneficial to arrange and install the clamp tube 30 and the wires in parallel within the limited space of the snake bone 22, and it can meet the design requirements of the large diameter of the clamp tube 30. At the same time, the endoscope tip 10 and the snake bone 22 are also eccentrically set, which can avoid the problem of the rivet 222 squeezing the clamp tube 30 and causing the clamp tube 30 channel to become smaller during the assembly of the snake bone 22 and the clamp tube 30. In addition, it can also prevent the rivet 222 from squeezing and damaging the clamp tube 30 during long-term use of the endoscope 100.
[0060] In summary, the embodiments of this utility model provide an endoscope tip 10 and an endoscope 100. The distal end of the endoscope tip 10 has a peripheral surface 11 and an end face 12. The peripheral surface 11 includes a first conical surface 111 and at least one inclined surface 112. The first conical surface 111 is connected to the at least one inclined surface 112, and the at least one inclined surface 112 is inclined toward the end face 12. The end face 12 is connected to both the first conical surface 111 and the at least one inclined surface 112. In other words, the distal end of the endoscope tip 10 is a cone-shaped structure. Specifically, by setting a first cone surface 111 at the distal end of the endoscope tip 10, a guiding function can be achieved. At the same time, the peripheral surface 11 of the tip is chamfered to form an inclined surface 112, which can reduce the overall volume of the distal end of the tip. In conjunction with the first cone surface 111, while having a guiding effect, the contact area between the tip and the organ tissue is reduced, and the resistance is reduced accordingly, thereby facilitating cannulation and preventing the tip from scratching the organ tissue.
[0061] Endoscope 100 includes endoscope tip 10, which has all the functions and benefits of endoscope tip 10.
