Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an advanced component and an endoscope. Background Technology

[0002] An endoscope is a medical device used for disease diagnosis and treatment, capable of being inserted into a patient's body to observe lesions. Endoscopes typically have an insertion end for insertion into the patient and a control end for observation and manipulation by medical personnel; the insertion end can also be called the tip.

[0003] In related technologies, the outer shell of some endoscope tips is composed of multiple interconnected parts. For example, the outer shell of some duodenoscope tips is composed of two halves joined together, which are then assembled with the tip support. This involves numerous splicing points, leading to complex assembly operations. Furthermore, misalignment can easily occur between the two halves of the shell. When misalignment occurs, the edges of the shell become sharp, posing a safety hazard of scratching internal tissues. In such cases, the product needs to be reworked or scrapped, resulting in a high defect rate and impacting production efficiency. Utility Model Content

[0004] In view of this, the present invention provides an advanced component and an endoscope to solve the problems of complex assembly operations and high failure rate of existing endoscopes.

[0005] To solve the above problems, the technical solution of this utility model is implemented as follows:

[0006] An advanced component includes: an advanced support; a clamping assembly movably connected to the advanced support; a housing integrally formed and having an internal receiving cavity, the housing having an opening communicating with the receiving cavity, at least a portion of the advanced support connected to the clamping assembly being disposed within the receiving cavity via the opening; a window for the clamping assembly to extend from the side of the housing opposite to the clamping assembly; wherein, a flange is circumferentially provided on the advanced support corresponding to the opening, the flange abutting against the end of the housing with the opening to close the opening.

[0007] In some embodiments, the outer surface of the housing is a smooth curved surface.

[0008] In some embodiments, the tip assembly further includes a limiting block for defining the range of motion of the lifting clamp assembly, the limiting block being connected to the tip support and / or the housing and located within the window.

[0009] In some embodiments, the limiting block is provided with a plug-in portion, and the tip bracket is provided with a slot corresponding to the plug-in portion, and the plug-in portion is connected to the slot.

[0010] In some embodiments, the outer contour of the end of the cover opposite to the opening is hemispherical.

[0011] In some embodiments, the lifting clamp assembly includes: a lifting clamp movably connected to the tip support; and a traction line connected to the lifting clamp to drive the lifting clamp to move; wherein the tip support has a guide hole for guiding the movement of the traction line, and the traction line passes through the guide hole.

[0012] In some embodiments, the lifting clamp has a fixing hole, and the traction line passes through the fixing hole; wherein, the lifting clamp assembly further includes a fixing post, which passes through the fixing hole to fix the traction line to the lifting clamp.

[0013] In some embodiments, the tip assembly further includes a pivot shaft, through which the lifting clamp is movably connected to the tip support.

[0014] In some embodiments, the tip support has a mounting groove, and the lifting clamp is movably mounted in the mounting groove via the pivot.

[0015] This utility model embodiment also provides an endoscope, including a main body and the aforementioned tip assembly, wherein the main body is at least connected to the tip support.

[0016] The tip assembly and endoscope provided in this embodiment of the invention include a tip support, a lifting clamp assembly, and a housing. The lifting clamp assembly is movably connected to the tip support. The housing adopts a one-piece molding design, which not only eliminates the need for additional splicing and assembly operations on the housing, simplifying the assembly process of the tip assembly, but also ensures a relatively complete overall shape of the housing, eliminating the possibility of sharp edges due to splicing misalignment. This allows for mass production with high quality consistency, improving production efficiency and reducing production costs. Furthermore, by creating an opening in the housing and having a corresponding flange on the tip support circumferentially positioned around the opening, accurate assembly of the tip support and housing can be achieved by aligning and connecting the opening and the flange. The flange effectively closes the opening, facilitating assembly operations and enabling positioning during assembly, reducing misalignment problems and improving assembly quality.

[0027] An endoscope is a medical device used for disease diagnosis and treatment. It can be inserted into a patient's body to observe lesions. Depending on the site of observation, endoscopes can be classified into types such as duodenoscopes, rectoscopes, and gastroscopes. Different types of endoscopes have different structures, but they all have an insertion end for insertion into the patient's body and a control end for medical personnel to observe and operate. The insertion end, also called the tip, usually contains components such as a camera module and a light source, while the control end usually contains observation and operating devices. The tip and control end are connected by a thin tube containing a delivery tube for air, water, and other substances, as well as several traction lines connecting to the operating devices. When using an endoscope, medical personnel can insert the tip into a designated location within the patient's body to observe lesions through the observation devices. If necessary, substances such as water or air can be delivered through the delivery tube to clean the camera module and maintain a clear field of view. The position of the tip can also be adjusted through the operating devices to observe different sites or facilitate insertion and removal of the tip. In some types of endoscopes, such as duodenoscopes, a lifting forceps is also provided at the tip to assist in surgical operations. The lifting forceps is connected to the operating device via a traction line. Specifically, one end of the traction line is fixed to the lifting forceps, and the other end is connected to the operating device. Medical staff drive the traction line to move through the operating device, which in turn moves the lifting forceps to perform the required surgical operations, such as grasping diseased tissue.

[0028] like Figure 1 As shown, this embodiment of the invention provides an end-point component 1, which is applied to an endoscope, such as a duodenoscope that requires a forceps lifter. Figure 2 and Figure 3 As shown, the tip assembly 1 includes a tip support 11, a clamping assembly 12, and a housing 13. The clamping assembly 12 is movably connected to the tip support 11. The housing 13 is an integrally formed component, with a receiving cavity 131 formed inside. The housing 13 has an opening 132 communicating with the receiving cavity 131. The tip support 11 can extend into the receiving cavity 131 through the opening 132, so that at least the portion of the tip support 11 connected to the clamping assembly 12 is located within the receiving cavity 131. A window 133 is also provided on the side of the housing 13 opposite to the clamping assembly 12. The window 133 communicates with the receiving cavity 131 to allow the clamping assembly 12 to extend out during movement. The specific shape and size of the window 133 are not further limited, as long as they meet the space requirements for the movement of the clamping assembly 12. Meanwhile, a flange 111 is provided on the front support 11 in the circumferential direction corresponding to the opening 132. When the front support 11 is assembled with the cover 13, the flange 111 abuts against the end of the cover 13 where the opening 132 is opened, so as to close the opening 132.

[0029] Specifically, the tip support 11 is used to install components required for the tip position of the endoscope. The shape and size of the tip support 11 are usually designed according to the installation position and size of the components to be installed. In addition to the lifting clamp assembly 12, the tip support 11 usually also houses structures such as a camera module, a lighting lamp, and a delivery tube. These structures are usually spaced apart from the lifting clamp assembly 12 to allow sufficient space for the movement of the lifting clamp assembly 12. The cover 13 is used to cover part of the structure of the tip support 11, which can improve the integrity of the tip assembly 1's shape and enhance its overall aesthetics. Furthermore, it can cover any sharp edges that may exist on the tip support 11, thereby better preventing the risk of scratching internal tissues when these sharp edges enter the body and improving the tactile comfort of the tip assembly 1.

[0030] Specifically, the housing 13 is designed as a single piece, meaning it is an indivisible, complete structure. This means that the housing 13 is not assembled from multiple parts during manufacturing. However, after molding, the housing 13 can still be processed using techniques such as cutting and grinding to remove material, further optimizing its shape and structure. For example, this can improve the fit between the housing 13 and the front support 11, or remove sharp edges. Optionally, features such as the receiving cavity 131, opening 132, and window 133 on the housing 13 can be formed directly during the single-piece molding process, or they can be formed separately after molding. Alternatively, some features can be formed during molding while others are formed through subsequent processing, as long as the housing 13 is an indivisible, complete structure after manufacturing. By adopting a single-piece molding structure, the housing 13 can be directly assembled with the front support 11 after manufacturing, without any assembly or splicing operations on the housing 13 itself, simplifying the assembly process. Furthermore, since the housing 13 is not composed of multiple parts, misalignment at the joints will not occur, thus avoiding problems such as sharp edges at the joints leading to rework or scrap. In addition, the housing 13 can use the same molding process during mass production, thereby improving production efficiency, reducing production costs, and ensuring better consistency of finished products.

[0031] Specifically, such as Figure 2 and Figure 3As shown, the flange 111 on the tip support 11 corresponds circumferentially to the opening 132, meaning that the flange 111 is set along the edge of the opening 132. For example, when the opening 132 is circular, the flange 111 can be set as an annular ring to correspond to the circumference of the circle, so that when the flange 111 abuts against the end of the cover 13 where the opening 132 is located, the flange 111 is exactly positioned around the edge of the opening 132, thereby closing the opening 132. With this design, the shape of the flange 111 matches the shape of the opening 132. When the tip support 11 and the cover 13 are correctly assembled, the flange 111 can just close the opening 132. Therefore, it is easier to accurately locate the relative position of the flange 111 and the opening 132 during assembly, resulting in high positioning accuracy, reducing the problem of misalignment, and improving assembly quality.

[0032] Regarding the assembly connection between the tip support 11 and the housing 13, alternatively, in some embodiments, UV-curable adhesive can be applied to the edges of the flange 111 and / or the opening 132. After assembly, UV light is used for curing, thus completing the assembly connection between the tip support 11 and the housing 13. This assembly method is simple to operate and has good fixing reliability. Of course, the aforementioned UV-curable adhesive can be replaced with other adhesive materials, and the bonding and fixing assembly method can be replaced with welding, snap-fit ​​connection, or other methods, as long as a reliable connection between the tip support 11 and the housing 13 can be achieved.

[0033] The tip assembly 1 provided in this embodiment includes a tip support 11, a lifting clamp assembly 12, and a cover 13. The lifting clamp assembly 12 is movably connected to the tip support 11 and is disposed within the receiving cavity 131 formed by the cover 13 as the tip support 11 is assembled with the cover 13. The cover 13 adopts an integral molding design, thus eliminating the need for additional splicing operations on the cover 13 itself, effectively avoiding misalignment between spliced ​​parts and the problem of sharp edges; the finished cover 13 can be directly assembled with the tip support 11, simplifying the assembly process of the tip assembly 1; and, when the cover 13 is mass-produced, by adopting the same integral molding process, the production efficiency and consistency are high, and the production cost is low. Furthermore, by creating an opening 132 on the housing 13 and circumferentially providing a flange 111 on the tip support 11 corresponding to the opening 132, the flange 111 can guide and position the installation of the housing 13. When assembling the tip support 11 and the housing 13, the flange 111 is inserted into the opening 132, achieving accurate assembly and precisely closing the opening 132. The flange 111 facilitates positioning during assembly, reduces misalignment, and improves assembly quality. Moreover, during assembly, the connection between the tip support 11 and the housing 13 can be completed simply by using adhesive or other methods to fix the flange 111 at the edge of the opening 132, resulting in good fixation reliability, simple operation, and high assembly efficiency.

[0034] In some embodiments, such as Figure 2 As shown, the outer surface of the housing 13 is a smooth curved surface. Specifically, the housing 13 can be a hollow cylinder, with the opening 132 located on the end face of the cylinder and the window 133 located on the side face of the cylinder. This design ensures good shape integrity and aesthetics for the housing 13, and the outer surface of the housing 13 remains a relatively smooth curved surface without sharp edges, allowing for smoother insertion of the tip assembly 1 into the patient's body, reducing patient discomfort, and improving the safety and comfort of using the tip assembly 1.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the tip assembly 1 also includes a limiting block 14 for limiting the range of motion of the lifting clamp assembly 12. The limiting block 14 is connected to the tip support 11 and / or the housing 13 and is located within the window 133. Specifically, when the lifting clamp assembly 12 extends from the window 133 to its limit position, the limiting block 14 abuts against the lifting clamp assembly 12, thereby limiting further movement of the lifting clamp assembly 12. In some embodiments, the limiting block 14 can be located at one end of the window 133 near the opening 132. When the lifting clamp assembly 12 moves, the lifting clamp assembly 12 tilts outward relative to the window 133, and as the amplitude of movement increases, the lifting clamp assembly 12 gradually approaches the limiting block 14 and eventually abuts against the limiting block 14, indicating that the lifting clamp assembly 12 has reached its limit position. It is understood that the position, shape, size, etc., of the limiting block 14 can be flexibly designed according to the required range of motion of the lifting clamp assembly 12.

[0036] Regarding the connection method of the limiting block 14, optionally, the limiting block 14 can be connected only to the tip support 11, only to the cover 13, or simultaneously to both the tip support 11 and the cover 13. The connection method is quite flexible, as long as the limiting block 14 is located within the window 133 after the tip support 11 and the cover 13 are assembled. The above embodiment limits the range of motion of the lifting clamp assembly 12 by setting the limiting block 14 within the window 133. When the lifting clamp assembly 12 moves to its limit position, the limiting block 14 can prevent the lifting clamp assembly 12 from continuing to move. In this way, the operator can know whether the lifting clamp assembly 12 has moved to the correct position, which facilitates the operator to accurately control the movement of the lifting clamp assembly 12.

[0037] In some embodiments, such as Figure 2 and Figure 3As shown, the limiting block 14 is provided with a plug-in portion 141, and the tip bracket 11 has a slot 112 corresponding to the plug-in portion 141, with the plug-in portion 141 connected to the slot 112. In some embodiments, the tip bracket 11 can be assembled with the cover 13 first, and then adhesive material can be applied to the position of the slot 112 on the tip bracket 11 and / or the edge position of the window 133 corresponding to the edge of the limiting block 14. Finally, the plug-in portion 141 on the limiting block 14 is aligned with the slot 112 and connected, thereby achieving accurate installation and reliable fixation of the plug-in portion 141. In other embodiments, the limiting block 14 can also be first connected and fixed to the cover 13, and then the slot 112 on the tip bracket 11 is aligned with the position of the plug-in portion 141 and assembled and connected with the cover 13. The above embodiments, by adopting the design of connecting the plug-in portion 141 with the slot 112, can play a better positioning role during the assembly process of the limiting block 14 and the tip bracket 11, achieving accurate installation of the limiting block 14.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the outer contour of the end of the housing 13 opposite to the opening 132 is hemispherical. Specifically, the end of the housing 13 opposite to the opening 132 is usually the end that the tip assembly 1 first enters the body during use. When the contour shape of this end is set to hemispherical, the size of this end gradually decreases along the direction in which the tip assembly 1 enters the body, allowing the tip assembly 1 to enter the body with a smaller size. This reduces stimulation to the patient, alleviates the patient's discomfort, and the spherical curved surface allows for smoother entry into the body, thereby reducing the difficulty of inserting the endoscope into the body.

[0039] In some embodiments, the clamping assembly 12 includes a clamping device 121 and a traction line 122. The clamping device 121 is movably connected to the tip support 11, and the traction line 122 is connected to the clamping device 121 to drive the clamping device 121 to move. The tip support 11 has a guide hole 113 for guiding the movement of the traction line 122, and the traction line 122 passes through the guide hole 113. Specifically, one end of the traction line 122 is connected to the clamping device 121, and the other end is usually connected to a specific operating device. The operator can pull the traction line 122 through the operating device, thereby driving the clamping device 121 to move and extend out of the window 133, thereby performing the required operation. In some embodiments, a limit block 14 is also provided in the window 133. When the clamping device 121 moves to its limit position, the limit block 14 abuts against the clamping device 121, thereby limiting the range of movement of the clamping device 121. The above embodiment employs a guide hole 113 on the tip support 11, so that the traction line 122 can only move within the range defined by the guide hole 113. This can improve the accuracy of the movement of the traction line 122, thereby improving the accuracy of the movement of the clamp 121 driven by the traction line 122.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the tip assembly 1 also includes a rotating shaft 15, through which the lifting clamp 121 is movably connected to the tip support 11. Optionally, in some embodiments, a connecting hole 1211 can be provided on the lifting clamp 121, allowing the rotating shaft 15 to movably pass through the connecting hole 1211 and be fixedly connected to the tip support 11; in other embodiments, the rotating shaft 15 can also be fixedly connected to the lifting clamp 121 or integrally formed, with a hole provided on the tip support 11, allowing the rotating shaft 15 to movably pass through the hole, as long as the lifting clamp 121 can move relative to the tip support 11. With the above design, the movement of the lifting clamp 121 is a rotation about the axis of the rotating shaft 15, resulting in good stability and easy control of the movement state.

[0041] In some embodiments, such as Figure 3 As shown, the tip bracket 11 has a mounting groove 114, and the lifting clamp 121 is movably mounted in the mounting groove 114 via a rotating shaft 15. Optionally, in some embodiments, the rotating shaft 15 can be fixed in the mounting groove 114, and the lifting clamp 121 has a connecting hole 1211, which is movably connected to the rotating shaft 15, thereby enabling the lifting clamp 121 to be installed in the mounting groove 114. In other embodiments, the rotating shaft 15 can be fixed to the lifting clamp 121, or integrally formed with the lifting clamp 121, and a hole is formed in the inner wall of the mounting groove 114 formed in the tip bracket 11, allowing the rotating shaft 15 to movably pass through the hole, thereby installing the lifting clamp 121 in the mounting groove 114. The specific shape and size of the mounting groove 114 only need to be able to accommodate the lifting clamp 121 and allow the lifting clamp 121 to move. The above embodiment makes full use of the space of the tip bracket 11 by installing the lifting clamp 121 in the mounting groove 114, which helps to reduce the volume of the tip component 1. Furthermore, the mounting groove 114 can separate the lifting clamp 121 from other components, thereby better avoiding the problem of interference between the lifting clamp 121 and other components when it moves. The structure is reasonably and compactly arranged.

[0042] In some embodiments, such as Figure 4 As shown, the lifting clamp 121 has a fixing hole 1212, and the traction cable 122 passes through the fixing hole 1212. The lifting clamp assembly 12 also includes a fixing post 123, which also passes through the fixing hole 1212, thereby fixing the traction cable 122 to the lifting clamp 121.

[0043] Optionally, in some embodiments, the diameter of the fixing hole 1212 is set to be larger than the diameter of the traction wire 122, so that the traction wire 122 can be easily passed through the fixing hole 1212. At the same time, the diameter of the fixing post 123 is adapted to the diameter of the fixing hole 1212 or can be slightly smaller than the diameter of the fixing hole 1212. When the fixing post 123 is passed through the fixing hole 1212, the traction wire 122 can be squeezed against the inner wall of the fixing hole 1212 as the fixing post 123 is inserted, thereby achieving the clamping and fixing of the traction wire 122, and thus achieving a reliable connection between the traction wire 122 and the lifting clamp 121.

[0044] In some implementations, the diameter of the fixing post 123 may be slightly larger than the diameter of the fixing hole 1212, and the fixing post 123 has a certain degree of elasticity. During assembly, by pressing the fixing post 123 into the fixing hole 1212, an interference fit is formed between the fixing post 123 and the fixing hole 1212. In this way, the fixing post 123 is more secure and less prone to loosening, which can improve the reliability of fixing the traction line 122.

[0045] In some implementations, the surface of the fixing post 123 may be provided with a material layer with a high coefficient of friction and / or a relatively rough surface, or the fixing post 123 may be directly made of a material with a high coefficient of friction and / or a relatively rough surface. This increases the friction between the fixing post 123 and the traction line 122 and between the fixing post 123 and the fixing hole 1212 when the fixing post 123 contacts and is squeezed with the traction line 122. This can better prevent the traction line 122 from loosening or detaching from the fixing hole 1212, and improve the reliability of fixing the traction line 122 to the clamp 121.

[0046] In some implementations, the aforementioned friction-increasing material layer can also be provided on the inner wall of the fixing hole 1212, or on the surface of the portion of the traction wire 122 that passes through the fixing hole 1212. It is understood that there are various methods for fixing the traction wire 122 to the clamping device 121 by means of the fixing post 123 passing through the fixing hole 1212, allowing for flexible design.

[0047] The above embodiment employs a fixing hole 1212 on the lifting clamp 121. During assembly, the traction wire 122 and the fixing post 123 are sequentially passed through the fixing hole 1212. The fixing post 123 can then press the traction wire 122 into the fixing hole 1212, effectively restricting the movement of the traction wire 122. This ensures reliable fixation between the traction wire 122 and the lifting clamp 121. The structure is simple, and the assembly operation is convenient, which can improve assembly efficiency, simplify the assembly process, and reduce production costs.

[0048] In some embodiments, such as Figure 4As shown, the clamping device 121 also has a positioning hole 1213, and the traction wire 122 is sequentially passed through the positioning hole 1213 and the fixing hole 1212. Optionally, in some embodiments, the fixing hole 1212 and the positioning hole 1213 are both opened on the same side wall of the clamping device 121. The traction wire 122 can first pass through the positioning hole 1213 from one side of the side wall, and then fold back from the other side of the side wall to pass through the fixing hole 1212. Finally, the fixing post 123 can be passed through the fixing hole 1212 in the same direction as the traction wire 122 passing through the fixing hole 1212. In this way, the direction in which the fixing post 123 passes through the fixing hole 1212 is consistent with the traction wire 122, so that the traction wire 122 will not be pushed out of the fixing hole 1212 when installing the fixing hole 1212, which facilitates the installation operation. The above embodiment employs a positioning hole 1213 on the lifting clamp 121, through which the traction wire 122 passes. This provides better positioning for the traction wire 122 during assembly, reduces loosening of the traction wire 122, facilitates accurate installation, and improves assembly efficiency.

[0049] This invention also provides an endoscope, such as a duodenoscope, which includes a main body and the aforementioned tip assembly 1. The main body is at least connected to the tip support 11. In some embodiments, the main body includes an insertion tube and an operating part, with the tip support 11 and the operating part connected to both ends of the insertion tube. By pushing the insertion tube, the tip support 11 inserted into the body can be moved, thereby pushing the tip assembly 1 to the target site. By controlling the operating part, components such as the lifting forceps assembly 12 can be driven to perform specified actions, thereby realizing the relevant surgical operation.

[0050] The endoscope provided by this utility model, by adopting the aforementioned tip component 1, features a one-piece molded housing 13, resulting in high production efficiency and consistency, and low production cost. Furthermore, the end of the housing 13 with the opening 132 connects to the flange 111 on the tip support 11, ensuring high assembly accuracy and simplifying assembly operations. Therefore, this endoscope boasts high production efficiency and quality, and low cost. During use, the tip component 1 eliminates the safety hazard of scratching internal tissues due to sharp edges, preventing discomfort and enhancing safety and comfort during surgery or examination.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
