Technical Field

[0001] This application relates to the technical field of endoscopes, specifically to an endoscope mount and an endoscope. Background Technology

[0002] An endoscope is a medical device consisting of a long, thin tube that enters the human body through a natural passage or surgical incision to deliver an imaging component. This allows for comprehensive examination and treatment of internal organs. The imaging component of the endoscope is mounted on a tip, which has nozzles. These nozzles spray water or air onto the outer surface of the imaging component's lens to flush away any adhering foreign matter. To facilitate rapid and accurate detection of abnormal lesions, two imaging components with different functions are typically mounted on the endoscope's tip. With two imaging components, two corresponding nozzles are usually required, one nozzle for cleaning one imaging component, thus increasing the outer diameter of the tip. Summary of the Invention

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] Please see Figures 1 to 8 This application provides an endoscope tip mount, which will be described in detail below.

[0032] In this embodiment, the terminal block 11 is provided with a first mounting hole 111 for mounting the first imaging component 13, a second mounting hole 112 for mounting the second imaging component 14, a nozzle mounting hole 113 for mounting the nozzle 16, and a channel mounting hole 114 for mounting the instrument channel 12. The nozzle 16 is used to clean foreign matter adhering to the outer surface of the lenses of the first imaging component 13 and the second imaging component 14. The first mounting hole 111 and the second mounting hole 112 are arranged adjacent to each other. The center line connecting the nozzle mounting hole 113, the first mounting hole 111, and the second mounting hole 112, and the center line connecting the channel mounting hole 114, the first mounting hole 111, and the second mounting hole 112 are all triangular. The nozzle mounting hole 113 is located on one side of the first mounting hole 111 and the second mounting hole 112, and the channel mounting hole 114 is located on the other side of the first mounting hole 111 and the second mounting hole 112. The nozzle mounting hole 113 and the channel mounting hole 114 are both located between the first mounting hole 111 and the second mounting hole 112. It is understood that in this embodiment, the nozzle mounting hole 113 is located between the first mounting hole 111 and the second mounting hole 112, that is, the vertical projection of the center of the nozzle mounting hole 113 onto the straight line passing through the centers of the first mounting hole 111 and the second mounting hole 112 is located between the first mounting hole 111 and the second mounting hole 112. Similarly, in this embodiment, the channel mounting hole 114 is located between the first mounting hole 111 and the second mounting hole 112, that is, the vertical projection of the center of the channel mounting hole 114 onto the straight line passing through the centers of the first mounting hole 111 and the second mounting hole 112 is located between the first mounting hole 111 and the second mounting hole 112.

[0033] It is understood that the shapes of the first mounting hole 111 and the second mounting hole 112 in this embodiment match the outer contour shape of the corresponding imaging component. For example, when the outer contour of the imaging component is circular, the corresponding mounting hole can also be a circular hole. The shape of the nozzle mounting hole 113 in this embodiment can also match the outer contour shape of the nozzle 16, and the shape of the channel mounting hole 114 can also match the outer contour shape of the instrument channel 12. In this embodiment, the nozzle mounting hole 113 is located between the first mounting hole 111 and the second mounting hole 112, so that the nozzle 16 can simultaneously clean the outer surface of the lens of the first imaging component 13 and the second imaging component 14. This is beneficial to reduce the number of parts and the outer diameter of the tip seat. Moreover, the distance between the nozzle mounting hole 113 and the first mounting hole 111 and the second mounting hole 112 is relatively close and the difference in distance is small, ensuring that the liquid or gas sprayed by the nozzle 16 onto the outer surface of the lens of the first imaging component 13 and the second imaging component 14 has a sufficiently high pressure, and the cleaning effect of the nozzle 16 on the lens of the first imaging component 13 and the second imaging component 14 is good. In this embodiment, the channel mounting hole 114 is also located between the first mounting hole 111 and the second mounting hole 112, making the channel mounting hole 114, nozzle mounting hole 113, first mounting hole 111, and second mounting hole 112 arranged in a compact quadrilateral shape, further reducing the outer diameter of the tip seat. In some application scenarios, when the endoscope is an examination endoscope, the endoscope may not have the instrument channel 12, and the tip seat 11 may not have the channel mounting hole 114; when the endoscope is a therapeutic endoscope, the endoscope can allow the therapeutic instruments to pass through the instrument channel 12, in which case the tip seat 11 can have the channel mounting hole 114. When the tip seat 11 does not have the channel mounting hole 114, the first mounting hole 111, second mounting hole 112, and nozzle mounting hole 113 are still arranged in a triangular shape, and the first mounting hole 111, second mounting hole 112, and nozzle mounting hole 113 can be arranged around the center of the tip seat 11.

[0034] In one embodiment, such as Figure 1As shown, the line connecting the center of the first mounting hole 111 and the center of the second mounting hole 112 is the first line segment L1, and the line connecting the midpoint of the first line segment L1 and the center of the nozzle mounting hole 113 is the second line segment L2. The first line segment L1 and the second line segment L2 are perpendicular. At this time, the nozzle mounting hole 113, the first mounting hole 111, and the second mounting hole 112 are arranged in the most compact isosceles triangle, which can further reduce the outer diameter of the tip seat and avoid the situation where the tip seat cannot pass through the natural cavity of the human body to reach the required specific part due to the large outer diameter of the tip seat, or cause obvious discomfort to the patient. Moreover, the distance from the center of the nozzle mounting hole 113 to the center of the first mounting hole 111 is equal to the distance from the center of the nozzle mounting hole 113 to the center of the second mounting hole 112, so that the pressure of the liquid or gas sprayed by the nozzle 16 onto the outer surface of the lens of the first imaging component 13 and the second imaging component 14 is consistent, and the nozzle 16 has a sufficiently good cleaning effect on the lens of the first imaging component 13 and the second imaging component 14. In this embodiment, when the first line segment L1 and the second line segment L2 are almost perpendicular, it is equivalent to the first line segment L1 and the second line segment L2 being perpendicular. In some application scenarios, the first line segment L1 and the second line segment L2 may not be perpendicular, as long as the nozzle mounting hole 113 is located between the first mounting hole 111 and the second mounting hole 112.

[0035] In one embodiment, the line connecting the midpoint of the first line segment L1 and the center of the channel mounting hole 114 is the third line segment L3, and the first line segment L1 is perpendicular to the third line segment L3. The third line segment L3 can also be perpendicular to the first line segment L1, in which case the channel mounting hole 114, the first mounting hole 111, and the second mounting hole 112 also form a compact isosceles triangle, resulting in a smaller outer diameter of the endcap. In some applications, the third line segment L3 may not be perpendicular to the first line segment L1; this can be set as needed.

[0036] In one embodiment, such as Figure 2 , Figure 3 As shown, the tip base 11 is provided with a first connecting groove 122. The opening of the first connecting groove 122 faces the proximal end 17 of the tip base 11. The tip base 11 is provided with the first connecting groove 122. The first mounting hole 111 and the second mounting hole 112 extend from the bottom of the first connecting groove 122 to the distal end 18 of the tip base 11. The first connecting groove 122 makes the proximal end 17 near the first mounting hole 111 and the second mounting hole 112 connected. The first connecting groove 122 can correspond to the wider parts of the two imaging components. After installation, the two imaging components can be arranged close together in the first connecting groove 122, which is beneficial to reducing the outer diameter of the tip base.

[0037] In one embodiment, the wall of the first connecting groove 122 is provided with a first notch 121 communicating with the nozzle mounting hole 113. By setting the first notch 121, the nozzle 16 can be set as close as possible to the axis of the tip seat 11, which is also beneficial to reducing the outer diameter of the tip seat. In another embodiment, the wall of the first connecting groove 122 is also provided with a second notch 119 communicating with the channel mounting hole 114. By setting the second notch 119, the instrument channel 12 can also be set as close as possible to the axis of the tip seat 11, which is also beneficial to reducing the outer diameter of the tip seat.

[0038] In one embodiment, the tip seat 11 further includes a water pipe mounting hole 115 for mounting a water supply pipe 15, which is provided through the tip seat 11. The water pipe mounting hole 115 and the channel mounting hole 114 are located on the same side of the first mounting hole 111 and the second mounting hole 112. Because the size of the instrument channel is relatively large, the distance between the channel mounting hole 114 and the two mounting holes is greater than the distance between the nozzle mounting hole and the two mounting holes. This results in a relatively large amount of unused space around the channel mounting hole 115. When the water pipe mounting hole 115 and the channel mounting hole 114 are located on the same side, the water pipe mounting hole 115 can be arranged in this unused space without needing to increase the size of the tip seat to design the water pipe mounting hole 115. The space on the tip seat is utilized more fully, which is beneficial for reducing the outer diameter of the tip seat.

[0039] In one embodiment, the wall of the first connecting groove 122 is further provided with a third notch 120 communicating with the water pipe mounting hole 115. The third notch 120 allows the water supply pipe 15 to be positioned as close as possible to the axis of the tip seat 11, which also helps to reduce the outer diameter of the tip seat. In this embodiment, the water supply pipe 15 can be used to rinse the target area within the body to ensure that the imaging area of ​​the imaging component is not obstructed. In some applications, the water supply pipe 15 can provide the water required for cleaning the nozzle 16, or the water and air required for cleaning the nozzle 16 can be supplied separately by another delivery pipe.

[0040] In one embodiment, the water pipe mounting hole 115 and the channel mounting hole 114 are both stepped holes. The large-diameter holes of the water pipe mounting hole 115 and the channel mounting hole 114 are close to the proximal end 17 of the tip seat 11. The wall of the first connecting groove 122 is provided with a second notch 119 that communicates with the channel mounting hole 114. The second notch 119 connects the large-diameter hole of the channel mounting hole 114 with the first connecting groove 122. The third notch 120 connects the large-diameter hole of the water pipe mounting hole 115 with the first connecting groove 122. The step between the large-diameter hole and the small-diameter hole of the water pipe mounting hole 115 is the first step, and the step between the large-diameter hole and the small-diameter hole of the channel mounting hole 114 is the second step. The first step and the second step are located on the far end 18 side of the bottom of the first connecting groove 122. The first step abuts against the end of the water supply pipe 15, and the large-diameter hole of the water pipe mounting hole 115 can be bonded and fixed to the outer peripheral sidewall of the water supply pipe 15. The second step abuts against the end of the instrument channel 12, and the large-diameter hole of the channel mounting hole 114 can be bonded and fixed to the outer peripheral sidewall of the instrument channel 12. The first step is located on the far end 18 side of the bottom of the first connecting groove 122, which allows the far end 18 of the large-diameter hole of the water pipe mounting hole 115 to have a completely enclosed hole wall, and the airtightness of the bonding and fixing of the outer peripheral sidewall of the water supply pipe 15 to this part of the hole wall is good. The second step is located on the far end 18 side of the bottom of the first connecting groove 122, which allows the far end 18 of the large-diameter hole of the channel mounting hole 114 to also have a completely enclosed hole wall, and the airtightness of the bonding and fixing of the outer peripheral sidewall of the instrument channel 12 to this part of the hole wall is also good, ensuring good airtightness of the tip after installation. In this embodiment, the small diameter holes of the water pipe mounting hole 115 and the small diameter holes of the channel mounting hole 114 are located near the far end 18 of the tip seat 11 and are used to supply water in the water pipe 15 and allow instruments in the instrument channel 12 to pass through.

[0041] In one embodiment, the proximal end 17 of the tip seat 11 is provided with a hollow shaft section 116 for connecting the curved portion of the endoscope. The side wall of the water pipe mounting hole 115 is provided with a fourth notch 117, and the side wall of the channel mounting hole 114 is provided with a fifth notch 118. Both the fourth notch 117 and the fifth notch 118 extend to the inner side wall of the hollow shaft section 116. In this embodiment, the curved portion is bent by axially pulling the traction steel wire rope, causing the adjacent curved sections of the curved portion to rotate relative to each other. The distal end 18 of the curved portion is connected to the hollow shaft section 116 of the tip seat 11, and the proximal end 17 of the curved portion is connected to the insertion tube. Because the fourth notch 117 and the fifth notch 118 penetrate to the inner wall of the hollow shaft section 116, when the tip seat 11 is connected to the curved part, part or all of the end of the curved part extends into the hollow shaft section 116. The curved part can squeeze the instrument channel 12 and the water supply pipe 15 towards the axis of the tip seat 11. The instrument channel 12 and the water supply pipe 15 have space for deformation and displacement. Under the premise of ensuring smooth flow, the curved part can be connected with a smaller outer diameter of the tip seat 11.

[0042] In one embodiment, such as Figure 7 , Figure 8 As shown, the front end seat 11 is also provided with a second connecting groove 123, which is located between the first mounting hole 111 and the second mounting hole 112. The second connecting groove 123 forms a notch on the hole wall of the first mounting hole 111 and the second mounting hole 112, connecting the first mounting hole 111 and the second mounting hole 112. Through the second connecting groove 123, the first imaging component 13 and the second imaging component 14 can be pre-connected as an integral structure, and then installed in the first mounting hole 111 and the second mounting hole 112 at once. The second connecting groove 123 provides clearance for the connection part between the first imaging component 13 and the second imaging component 14. In one embodiment, the housing of the first imaging component 13 and the second imaging component 14 can be an integral structure, which results in higher integration of the front end components and simplifies assembly. In some embodiments, the second connecting groove 123 can extend along the axial direction of the front end seat 11 to the bottom of the first connecting groove 122, so that the second connecting groove 123 communicates with the first connecting groove 122. In some application scenarios, the second connecting groove 123 may not be provided between the first mounting hole 111 and the second mounting hole 112.

[0043] In the endoscope tip mount of the above embodiment, the nozzle mounting hole 113 is located between the first mounting hole 111 and the second mounting hole 112, allowing the nozzle 16 to simultaneously clean the outer surfaces of the lenses of the first imaging assembly 13 and the second imaging assembly 14. This helps reduce the number of components and the outer diameter of the tip mount. Furthermore, the nozzle mounting hole 113 is close to both the first and second mounting holes 111 and 112, ensuring that the liquid or gas sprayed by the nozzle 16 onto the outer surfaces of the lenses of the first and second imaging assemblies 13 and 14 has sufficient pressure, resulting in good cleaning of the lenses of both components. In this embodiment, the channel mounting hole 114 is also located between the first and second mounting holes 111 and 112, creating a compact quadrilateral arrangement of the channel mounting hole 114, nozzle mounting hole 113, first mounting hole 111, and second mounting hole 112, further reducing the outer diameter of the tip mount.

[0044] Please see Figures 1-9 This application embodiment also provides an endoscope, including an endoscope tip seat 11 as described above, a first imaging component 13 installed in a first mounting hole 111, a second imaging component 14 installed in a second mounting hole 112, a nozzle 16 installed in a nozzle mounting hole 113, and an instrument channel 12 installed in a channel mounting hole 114; the nozzle 16 sprays water towards the first imaging component 13 and the second imaging component 14.

[0045] It is understood that the tip seat 11 in this embodiment is the same as in the above embodiment, and will not be described again here. After the first imaging component 13, the second imaging component 14, the nozzle 16, and the instrument channel 12 in this embodiment are installed, the first imaging component 13 and the second imaging component 14 are arranged adjacent to each other. The center line connecting the nozzle 16, the first imaging component 13, and the second imaging component 14, and the center line connecting the instrument channel 12, the first imaging component 13, and the second imaging component 14 are all triangular. The nozzle 16 is located on one side of the first imaging component 13 and the second imaging component 14, and the instrument channel 12 is located on the other side of the first imaging component 13 and the second imaging component 14. The nozzle 16 and the instrument channel 12 are both located between the first imaging component 13 and the second imaging component 14. In the above embodiments, one side of the first imaging component 13 and the second imaging component 14, and one side of the first mounting hole 111 and the second mounting hole 112, are all relative positions of corresponding structures on the cross-section of the tip seat 11. The aforementioned centers are all the centers of the corresponding structures on the cross-section of the tip seat 11, and the cross-section is perpendicular to the axis of the tip seat 11. In this embodiment, the first imaging component 13 and the second imaging component 14 can have different functions; for example, one can be for imaging under normal light and the other under special light, or one can be for imaging at normal magnification and the other at magnification. In this embodiment, the nozzle 16 faces the first imaging component 13 and the second imaging component 14, allowing simultaneous cleaning of both imaging components. The spray area of ​​the nozzle 16 only needs to cover both imaging components. In this embodiment, the instrument channel 12 provides an insertion channel for instruments needed for diagnosis or treatment. In some application scenarios, when the endoscope is an examination endoscope, the endoscope may not have an instrument channel 12, and the tip seat 11 may not have a channel mounting hole 114.

[0046] The endoscope in this embodiment may also include other functional structures, such as a curved section, an insertion tube 20, a handle 19, and a control system. The proximal end 17 of the insertion tube 20 is connected to the handle 19, and the distal end 18 is connected to the curved section. The distal end 18 of the curved section is connected to the hollow shaft section 116 of the tip seat 11. The distal end 18 is the end away from the handle, and the proximal end 17 is the end closer to the handle.

[0047] In the endoscope of the above embodiment, the nozzle 16 is located between the first imaging component 13 and the second imaging component 14, allowing the nozzle 16 to simultaneously clean the outer surfaces of the lenses of both the first imaging component 13 and the second imaging component 14. This helps reduce the number of components and the outer diameter of the tip mount 11. Furthermore, the close proximity and small distance difference between the nozzle 16 and both the first and second imaging components 13 and 14 ensure that the liquid or gas sprayed by the nozzle 16 onto the outer surfaces of the lenses of both components has sufficient pressure, resulting in good cleaning of the lenses of both components. In this embodiment, the instrument channel 12 is also located between the first and second imaging components 13 and 14, creating a compact quadrilateral arrangement of the instrument channel 12, nozzle 16, first imaging component 13, and second imaging component 14, further reducing the outer diameter of the tip mount 11.

[0048] 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.
