Description

An endoscope, its tip assembly, and a method for manufacturing the tip assembly. Technical Field

[0001] This application relates to the field of endoscope technology, and more specifically to an endoscope, its tip assembly, and a method for manufacturing the tip assembly. Background Technology

[0002] An endoscope is a diagnostic instrument integrating traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. With the rapid development of science and technology and medical technology in recent years, minimally invasive or non-invasive endoscopic medical examinations and treatments have become widely used. An endoscope can be inserted into the human body through natural passages or surgical incisions to examine or treat internal organs. On the one hand, the size of the endoscope, especially the maximum size of its tip, can affect the patient's experience and limit its application; on the other hand, an endoscope is an important tool for doctors in diagnosing diseases, and its image quality directly affects the accuracy and effectiveness of the diagnosis. Summary of the Invention

[0003] This application provides an endoscope, its tip assembly, and a method for manufacturing the tip assembly. It can reduce the size of the tip assembly, expand its application range, and solve the problems of poor image quality and inconsistent image quality caused by the contact between the adhesive and the light-emitting surface, so as to achieve better image quality.

[0004] This application provides an endoscope tip component, including:

[0005] A camera module, used to acquire images of the target location;

[0006] An illumination module, wherein the illumination module is used to provide a light source to the target location; and

[0007] A head-end base has a proximal end and a distal end disposed opposite to each other, and the head-end base has a module mounting hole and an illumination mounting hole that are interconnected. The module mounting hole extends through the head-end base in a direction from the proximal end to the distal end. At least a portion of the camera module is adhered to the distal end of the module mounting hole by an adhesive. The illumination mounting hole is used to mount an illumination module, and a groove is provided between the distal end face of the illumination mounting hole and the distal end face of the module mounting hole to limit the diffusion of the adhesive.

[0008] In some optional embodiments, the trench includes a trench distal end face, a first side face, a second side face, and a third side face. The first side face is connected to the distal end face of the lighting mounting hole. The second side face and the third side face are disposed opposite each other on both sides of the first side face. The trench distal end face is connected to the distal ends of the first side face, the second side face, and the third side face to form a structure that is open at the proximal end and on the side facing the module mounting hole, so that the lighting mounting hole, the module mounting hole, and the trench are interconnected.

[0009] In some optional embodiments, the distal end face of the trench, the first side face, the second side face, and the third side face are planar or curved structures.

[0010] In some optional embodiments, the distal end of the headstock is further provided with a filling groove, the filling groove is arranged circumferentially along the module mounting hole, the proximal end face of the filling groove communicates with the distal end face of the groove, and the filling groove is filled with the adhesive.

[0011] In some optional embodiments, the adhesive is also provided in the proximal end of the lighting mounting hole and / or the module mounting hole, with the distal end of the adhesive in the lighting mounting hole and / or the module mounting hole spaced apart from the proximal end of the lighting module to form an air gap.

[0012] In some optional embodiments, the distal end face of the lighting module is disposed close to the distal end face of the lighting mounting hole, and the distal end face of the camera module is disposed exposed outside the distal end face of the module mounting hole.

[0013] The lighting module includes two lighting units, which are respectively arranged radially on the outer surface of the camera module. The lighting mounting hole and the module mounting hole are coaxially arranged, and the lighting mounting hole is located on both sides of the module mounting hole.

[0014] In some optional embodiments, the proximal end of the headstock is provided with an insertion tube interface for connecting to an insertion tube at the proximal end of the headstock, and the distal end face of the insertion tube interface is located between the proximal end face and the distal end face of the lighting mounting hole.

[0015] The outer side of the distal end of the headstock is provided with a positioning notch, which is used for directional positioning during the installation of the camera module.

[0016] This application also provides an endoscope including the aforementioned tip component.

[0017] This application also provides a method for manufacturing an endoscope tip assembly, used to manufacture the tip assembly as described above, the steps of which include:

[0018] A head end seat is provided with a module mounting hole and a lighting mounting hole, the head end seat having a proximal end and a distal end disposed opposite to each other;

[0019] An integrated structure comprising a camera module and an illumination module is inserted from the proximal end, such that the camera module is at least partially located within the module mounting hole, and the illumination module is located within the illumination mounting hole;

[0020] An adhesive is filled between the distal end of the module mounting hole and the camera module, and the adhesive is allowed to climb along the gap between the camera module and the module mounting hole and part of the structure of the groove, such that the camera module is at least partially embedded in the adhesive, and such that the adhesive is away from the distal end face of the lighting module.

[0021] The adhesive is hardened using physical or chemical methods to fill and connect the gap between the module mounting hole and the camera module.

[0022] In some optional embodiments, the step further includes: filling the proximal end of the module mounting hole and / or the lighting mounting hole with an adhesive, allowing the adhesive to flow along the space within the hole, and ensuring that there is at least a partial air gap between the distal end of the lighting mounting hole and the distal end of the adhesive.

[0023] The endoscope's tip assembly according to the above embodiments includes a camera module, an illumination module, and a headstock. The headstock has a proximal end and a distal end disposed opposite to each other. The headstock has a module mounting hole and an illumination mounting hole that communicate with each other. The module mounting hole extends through the headstock from the proximal end to the distal end. At least a portion of the camera module is adhered to the distal end of the module mounting hole by an adhesive. The illumination mounting hole is used to mount the illumination module, and a groove is provided between the distal end face of the illumination mounting hole and the distal end face of the module mounting hole to limit the diffusion of the adhesive. Because the module mounting hole and the illumination mounting hole are formed within the headstock and are interconnected without any obstruction, the overall size of the headstock can be reduced, facilitating its entry into various narrow passages within the human body and expanding the scope of endoscope use. Because a groove is provided between the far end face of the lighting mounting hole and the far end face of the module mounting hole, the gap between the module mounting hole and the camera module can be locally increased, thereby reducing the capillary effect, limiting the diffusion of the adhesive, and preventing the adhesive from contacting the light-emitting surface. This solves the problem of poor image quality and inconsistent image quality caused by the adhesive contacting the light-emitting surface, so as to achieve better image quality and improve the user experience.

[0035] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0036] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0037] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0038] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0039] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0040] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0041] To more clearly describe the structure of this application, the terms "proximal" and "distal" are used as directional terms. "Proximal" means the end of the structure that is closer to the operator when in use, and "distal" means the end of the structure that is farther from the operator when in use, that is, the end that is closer to the patient or inserted into the patient's body.

[0042] This application provides an endoscope, which can be a laparoscope, pyeloscope, etc. Referring to Figure 1, the endoscope includes an operating handle (not shown in the figure), an insertion tube (not shown in the figure), and a tip assembly 1. The insertion tube is disposed at the proximal end of the tip assembly 1, and the operating handle is disposed at the proximal end of the insertion tube. At least a portion of the insertion tube is inserted into or fixed to the operating handle. The insertion tube can be inserted to a target position, and the operating handle can control the movement and rotation of the insertion tube and the tip assembly 1 to adjust their position.

[0043] Please refer to Figures 1 to 10. The front-end assembly 1 includes a camera module 11, an illumination module 12, and a head mount 13. The camera module 11 is used to acquire images of the target location, and the illumination module 12 is used to provide a light source to the target location. The head mount 13 has a proximal end and a distal end that are arranged opposite to each other. The distal end of the head mount 13 can define the distal end of the front-end assembly 1, and the proximal end can define the proximal end of the front-end assembly 1. The proximal end of the head mount 13 is an open structure so that other structural components can be inserted into the head mount 13. The head end seat 13 has interconnected module mounting holes 131 and lighting mounting holes 132, with at least one side of the module mounting holes 131 and lighting mounting holes 132 overlapping. The module mounting holes 131 extend through the head end seat 13 in a direction from the proximal end to the distal end and are used to mount the module. At least a portion of the camera module 11 is adhered (or attached) to the distal end of the module mounting holes 131 by an adhesive. The lighting mounting holes 132 are used to mount the lighting module 12, and a groove 133 is provided between the distal end face of the lighting mounting holes 132 and the distal end face of the module mounting holes 131. The groove 133 is used to limit the diffusion of the adhesive.

[0044] Since the module mounting hole 131 and the lighting mounting hole 132 are formed inside the headstock 13 and are interconnected without any obstruction, it helps to reduce the external size of the headstock 13, making it easier for the headstock 13 to enter various narrow channels in the human body and thus expanding the scope of use of the endoscope.

[0045] Understandably, considering cost and installation difficulty, the camera module 11 is adhered to the module mounting hole 131 with adhesive to achieve a fixed connection between the two. However, adhesive is generally in liquid form and has a certain degree of fluidity, which may flow to the light-emitting surface of the lighting module 12. Based on this possibility, it will affect the final image quality formed by the camera module 11.

[0046] The distal end of the lighting mounting hole 132 does not penetrate the head end seat 13, resulting in a thin-walled structure at its distal end, which can protect the light-emitting surface. However, in order to better fix and position the camera module 11, the gap between the camera module 11 and the module mounting hole 131 should be as small as possible during assembly. The presence of small gaps can easily generate capillary effects, and the adhesive, based on capillary effects, can flow along the gap between the camera module 11 and the module mounting hole 131 and easily flow to the light-emitting surface, causing the protective effect of the thin-walled structure on the light-emitting surface to fail.

[0047] To address the aforementioned issues, this application creatively incorporates a groove 133 between the distal end face of the lighting mounting hole 132 and the distal end face of the module mounting hole 131. The groove 133 partially increases the gap between the module mounting hole 131 and the camera module 11, thereby reducing capillary effects, limiting adhesive diffusion, and preventing the adhesive from contacting the light-emitting surface. This solves the problem of poor image quality and inconsistent image quality caused by the adhesive contacting the light-emitting surface, achieving better image quality and enhancing the user experience for operators and patients.

[0048] Referring to Figures 3 and 4, in some embodiments, the groove 133 includes a groove distal end face 1331, a first side face 1332, a second side face 1333, and a third side face 1334. The first side face 1332 is connected to the distal end face of the lighting mounting hole 132. The second side face 1333 and the third side face 1334 are disposed opposite each other on both sides of the first side face 1332. The groove distal end face 1331 is connected to the distal ends of the first side face 1332, the second side face 1333, and the third side face 1334 to form a structure that is open at the proximal end and on the side facing the module mounting hole 131, so that the lighting mounting hole 132, the module mounting hole 131, and the groove 133 are interconnected. This can reduce the cavity wall configuration for forming the hole structure, thereby contributing to the miniaturization design of the head end seat 13.

[0049] In some embodiments, the distal end face 1331, the first side face 1332, the second side face 1333, and the third side face 1334 of the trench can all be planar structures. The distal end face 1331 of the trench extends in a direction perpendicular to the proximal end to the distal end. The first side face 1332 is connected to the distal end face of the lighting mounting hole 132. The second side face 1333 and the third side face 1334 are disposed opposite to each other on both sides of the first side face 1332, and the first side face 1332, the second side face 1333, and the third side face 1334 extend in a direction parallel to the proximal end to the distal end. The second side face 1333 and / or the third side face 1334 are planar structures. Three sides 1334 are connected to or overlap with the module mounting hole 131, and the second side 1333 and / or the third side 1334 are connected to or overlap with the lighting mounting hole 132. The groove distal end face 1331 and the first side face 1332 are connected to form a stepped structure. When the camera module 11 is installed in the module mounting hole 131 and fixed at the distal end, the stepped structure increases the gap between the camera module 11 and the side of the module mounting hole 131, weakens the capillary effect of the adhesive in the gap, and thus effectively prevents the adhesive from climbing along the distal end face of the lighting mounting hole 132 and contacting the light-emitting surface.

[0050] In other embodiments, the trench distal end face 1331, the first side face 1332, the second side face 1333, and the third side face 1334 can all be planar structures. An included angle (acute or obtuse) is formed between the trench distal end face 1331 and the first side face 1332, the second side face 1333, and the third side face 1334, which can also increase the gap between the camera module 11 and the side of the module mounting hole 131.

[0051] In some embodiments, at least one of the trench distal end face 1331, the first side face 1332, the second side face 1333, and the third side face 1334 can be a curved surface structure. For example, the first side face 1332, the second side face 1333, and the third side face 1334 are curved surface structures and are continuously arranged to form a smooth arc surface.

[0052] Referring to Figures 6 and 7, in some embodiments, the distal end of the headstock 13 is further provided with a filling groove 134. The filling groove 134 is arranged circumferentially along the module mounting hole 131. The proximal end face of the filling groove 134 communicates with the distal end face of the groove 133, and a portion of the side surface of the module mounting hole 131 is provided between the proximal end face of the filling groove 134 and the distal end face of the groove 133. This portion of the side surface enables communication between the filling groove 134 and the groove 133. The filling groove 134 is filled with adhesive. During assembly, adhesive can be filled from the distal end to the proximal end, and some adhesive can fill the filling groove 134 to achieve the connection between the camera module 11 and the module mounting hole 131. Due to the provision of the filling groove 134, some adhesive can be stored, improving the reliability of the connection between the module mounting hole 131 and the camera module 11.

[0053] Referring to Figure 8, in some embodiments, an adhesive is also provided in the proximal end of the lighting mounting hole 132 and / or the module mounting hole 131. This portion of the adhesive is filled from the proximal end, and the distal end of the adhesive in the lighting mounting hole 132 is spaced apart from the proximal end of the lighting module 12, so that an air gap 1321 is formed between this portion of the adhesive and the distal end face (or the proximal end face of the light-emitting surface) of the lighting mounting hole 132. This can further improve the installation stability of the camera module 11 and reduce the possibility of this portion of the adhesive contacting the light-emitting surface.

[0054] For ease of distinction and illustration, the adhesive between the camera module 11 and the module mounting hole 131 is defined as the first adhesive 14, and the adhesive inside the lighting mounting hole 132 and / or the module mounting hole 131 is defined as the second adhesive 15, as shown in Figure 8.

[0055] It should be understood that the module mounting hole 131 mentioned above is used to install the camera module 11, but it does not mean that the camera module 11 is completely installed inside the module mounting hole 131. On the contrary, the camera module 11 may have at least a part of its structure exposed outside the module mounting hole 131 (or head end seat 13). For example, the far end face of the camera module 11 is exposed outside the far end face of the module mounting hole 131.

[0056] In some embodiments, the distal end face of the lighting module 12 is positioned close to the distal end face of the lighting mounting hole 132, that is, the distal end face of the light-emitting surface of the lighting module 12 and the distal end face of the lighting mounting hole 132 can coincide, or the distal end face of the light-emitting surface of the lighting module 12 and the distal end face of the lighting mounting hole 132 can be spaced apart, with a small gap between them (this gap can be intentionally designed during the structural design or formed by processing errors), which can prevent a "hard-on-hard" collision between the light-emitting surface and the distal end face of the lighting mounting hole 132, thus protecting the light-emitting surface.

[0057] Referring to Figure 9, in some embodiments, the lighting module 12 includes two lighting units 121, which are radially disposed on the outer side of the camera module 11 and are integrally formed with the camera module 11, facilitating integrated assembly and simplifying assembly steps. To accommodate this structure, the lighting mounting hole 132 and the module mounting hole 131 are coaxially arranged, with the lighting mounting hole 132 correspondingly disposed on both sides of the module mounting hole 131, such that the sides of the lighting mounting hole 132 and the module mounting hole 131 overlap.

[0058] Of course, in other embodiments, when the lighting module 12 includes a lighting unit 121, the lighting unit 121 is disposed on the outer side of the camera module 11, and the lighting mounting hole 132 and the module mounting hole 131 are arranged radially along the head end seat 13, with only a portion of their sides overlapping. When the lighting module 12 has three or more lighting units, the lighting mounting holes 132 can be arranged around the module mounting holes 131.

[0059] Please continue to refer to Figure 2. In some embodiments, the proximal end of the head end seat 13 is provided with an insertion tube interface 135. The insertion tube interface 135 is used to connect with the insertion tube at the proximal end of the head end seat 13. The distal end face of the insertion tube interface 135 is located between the proximal end face and the distal end face of the lighting mounting hole 132, and also between the proximal end face and the distal end face of the module mounting hole 131, so that the insertion tube can be inserted into the head end seat 13 for easy and secure connection.

[0060] Referring to Figure 10, in some embodiments, a positioning notch 136 is provided on the outer side of the distal end of the headstock 13. The positioning notch 136 is used for directional positioning during the installation of the camera module 11. The headstock 13 is generally a cylindrical structure, and the positioning notch 136 is formed by a partial recess of the sidewall of the cylindrical structure towards the center. The positioning notch 136 facilitates the determination of the front and back of the camera module 11 for correct installation. Correspondingly, referring to Figure 9, the camera module 11 may also be provided with a positioning mark 111. During assembly, the positioning notch 136 and the positioning mark 111 are aligned in the same direction, i.e., both are set upward, left, right, or downward.

[0061] The second embodiment of this application provides the aforementioned front-end component 1, the structure of which has been described in detail above and will not be repeated here.

[0062] A third embodiment of this application provides a method for manufacturing an endoscope tip assembly 1, used to manufacture the tip assembly as described above, the steps of which include:

[0063] A head end seat 13 is provided with a module mounting hole 131 and a lighting mounting hole 132, the head end seat 13 having a proximal end and a distal end disposed opposite to each other.

[0064] The integrated structure consisting of the camera module 11 and the lighting module 12 is inserted from the proximal end, such that the camera module 11 is at least partially located in the module mounting hole 131, and the lighting module 12 is located in the lighting mounting hole 132, as shown in Figure 6.

[0065] A first adhesive 14 is filled between the distal end of the module mounting hole 131 and the camera module 11, and the first adhesive 14 is allowed to climb along the gap between the camera module 11 and the module mounting hole 131 and part of the structure of the groove 133, so that the camera module 11 is at least partially embedded in the first adhesive 14, and the first adhesive 14 is away from the distal end face of the lighting module 12, as shown in FIG7.

[0066] The first adhesive 14 is hardened by physical or chemical methods so that it fills and connects the gap between the module mounting hole 131 and the camera module 11.

[0067] In some embodiments, the steps of the above manufacturing method further include: filling the proximal end of the module mounting hole 131 and / or the lighting mounting hole 132 with a second adhesive 15, allowing the second adhesive 15 to flow along the space within the hole, and ensuring that there is at least a partial air gap 1321 between the distal end of the lighting mounting hole 132 and the distal end of the second adhesive 15, as shown in FIG8. In this embodiment, the second adhesive 15 is also allowed to be cured by physical or chemical methods.

[0068] It should be noted that the first adhesive 14 and the second adhesive 15 are initially in a liquid state and have a certain degree of fluidity, which can increase the contact area between the first adhesive 14 and the camera module 11 and / or the module mounting hole 131, the second adhesive 15 and the lighting mounting hole 132, so that the first adhesive 14 and the second adhesive 15 can fill the mounting gap and increase the stability of the connection.

[0069] In one embodiment, the method described above for curing the first adhesive 14 and the second adhesive 15 using physical or chemical methods includes using special light illumination (e.g., curing by ultraviolet light).

[0070] The fourth embodiment of this application provides a method for manufacturing an endoscope, including the method for manufacturing the aforementioned tip component 1. The method for manufacturing the tip component 1 has been described in detail above and will not be repeated here.

[0071] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
