[0040] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0042] In the embodiments of the present application, "proximal end" and "distal end" refer to the relative position of each component to the user in the use environment, wherein the end closer to the user is designated as "proximal end", and the end farther from the user is designated as "distal end".

[0043] The inventor found that the first guide channel 140 for the instrument tube 340 to pass through and the second guide channel 150 for the signal line 350 to pass through occupy a certain installation area of the handle 200, causing the already limited space in the handle 200 to be more crowded, affecting the installation of other components in the handle 200.

[0044] The installation structure 100, the handle 200 and the endoscope 300 provided by the present application will be described in detail below in combination with the accompanying drawings Figures 1-9 and specific embodiments and their application scenarios.

The mounting structure 100 is used to fix the instrument tube 340 and the signal wire 350 in the handle 200 to realize the mounting of the instrument tube 340 and the signal wire 350.

[0047] As shown in the figure, the mounting structure 100 has a first guide channel 140 for the instrument tube 340 to pass through and a second guide channel 150 for the signal wire 350 to pass through. The first guide channel 140 plays a guiding and limiting role for the mounting of the instrument tube 340, and the second guide channel 150 also plays a guiding and limiting role for the mounting of the signal wire 350. By arranging the first guide channel 140 and the second guide channel 150, a mounting basis is provided for the mounting of the instrument tube 340 and the signal wire 350 in the handle 200. Figure 2 As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200.

[0048] Figure 2 As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200.

[0049] As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200. Figure 2 As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200.

[0050] Figure 2 As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200. Figure 9 As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200.

[0051] As shown in the figure, the first guide channel 140 and the second guide channel 150 are staggered in the mounting direction. By having a height difference in the mounting direction between the first guide channel 140 and the second guide channel 150, the longitudinal space of the handle 200 is utilized to complete the mounting of the instrument tube 340 and the signal wire 350 by the first guide channel 140 and the second guide channel 150, and the signal wire 350 is more conducive to being straight, and will not present a large degree of bending posture in order to avoid the instrument tube 340, thereby reducing the mounting area of the instrument tube 340 and the signal wire 350 in the handle 200.

[0052] ​​In use, the operator holds the handle 200 and moves it, so that the orientation and state of the handle 200 change. Because the rigidity of the signal line 350 is small, the signal line 350 is prone to sag under the influence of gravity during movement of the handle 200, causing the signal line 350 to fall out of the second guide channel 150. The instrument tube 340 has a certain rigidity and can be stably installed in the first guide channel 140, and the instrument tube 340 is also not prone to falling out of the first guide channel 140 during movement of the handle 200. Therefore, the use of the instrument tube 340 to limit the signal line 350 in the second guide channel 150 avoids the signal line 350 from falling out of the second guide channel 150 during movement of the handle 200.

[0053] As shown in Figure 2 , the mounting structure 100 has a plurality of support portions 122 on the outside of the bending direction of the first guide channel 140 to support the bending extension of the instrument tube 340. Because of the shape design of the handle 200, the instrument tube 340 needs to be bent and installed in the handle 200. The bending portion of the instrument tube 340 protrudes on one side in the bent state, and the plurality of support portions 122 are provided to support the instrument tube 340, avoiding the bending portion of the instrument tube 340 from collapsing due to lack of effective support.

[0054] As shown in Figure 2 , the support portions 122 extend along the bending direction of the first guide channel 140. By extending the support portions 122 along the bending direction of the first guide channel 140, the contact area of the support portions 122 and the instrument tube 340 can be increased, so that the support portions 122 better support the instrument tube 340.

[0055] As shown in Figure 2 , the support portions 122 are two, and the opposite sides of the two support portions 122 extend to opposite sides of the installation side opening 151, respectively. By extending the opposite sides of the two support portions 122 to opposite sides of the installation side opening 151, respectively, the length of the support portions 122 is increased as much as possible while ensuring that the support portions 122 do not affect the passage of the signal line 350 through the second guide channel 150, and the contact area of the support portions 122 and the instrument tube 340 is increased, further enabling the support portions 122 to better support the instrument tube 340.

[0056] As preferred in the embodiment, one of the support portions 122 is arranged close to the instrument mouth 210 of the handle 200, and the other support portion 122 is arranged away from the instrument mouth 210 of the handle 200. When the instrument tube 340 is bent and arranged in the handle 200, due to the shape design of the handle 200, the bending curvature of the bent portion of the instrument tube 340 is the largest close to the instrument mouth 210, and the bending curvature of the bent portion of the instrument tube 340 is the smallest away from the instrument mouth 210, and gradually tends to be flat. Therefore, by arranging one of the support portions 122 close to the instrument mouth 210 of the handle 200, the bent portion with the largest bending curvature of the instrument tube 340 can be effectively supported. By arranging the other support portion 122 away from the instrument mouth 210 of the handle 200, the bent portion with the smallest bending curvature of the instrument tube 340 can be guided, so that the distal end of the instrument tube 340 is distributed in the axial direction of the insertion portion 310.

[0057] As shown in Figure 2 and Figure 3 , the mounting structure 100 comprises a first mounting member 120 and a second mounting member 130 arranged in a spaced manner, the first mounting member 120 is provided with a first guide slot 121 for the signal line 350 to pass through, the second mounting member 130 is provided with a second guide slot 131 for the signal line 350 to pass through, and the first guide slot 121 and the second guide slot 131 constitute a second guide channel 150.

[0058] The signal line 350 passes through the first guide slot 121 and the second guide slot 131 to complete the installation of the signal line 350 in the handle 200, and the first guide slot 121 and the second guide slot 131 guide the signal line 350. The first mounting member 120 and the second mounting member 130 are arranged in a spaced manner, so that there is a certain space between the first mounting member 120 and the second mounting member 130, which can be used to assemble other components. By arranging the first mounting member 120 and the second mounting member 130 in a spaced manner, the space occupied by the second guide channel 150 in the handle 200 can be reduced, which not only ensures that the signal line 350 can be stably installed, but also optimizes the structural layout in the handle 200.

[0059] In the embodiment, as shown in Figures 1-3 , the second mounting member 130 is a plurality of. In the endoscope 300, the image information obtained by the camera module is transmitted to the host through the signal line 350, and the image information is displayed on the host. Therefore, the signal line 350 has a relatively long length, and a plurality of second mounting members 130 are arranged in the handle 200 along the length direction of the handle 200, which increases the total area of the second guide slot 131 in contact with the signal line 350, so that the signal line 350 can be more stably installed in the handle 200. The plurality of second mounting members 130 are arranged in a spaced manner, so that there is also a certain space between any two adjacent second mounting members 130, which can be used to assemble other components to make full use of the space in the handle 200.

[0060] As preferred in the present embodiment, the second mounting member 130 can be 2, 3, 4 or more, which can be flexibly set according to the use requirement, and the present embodiment does not limit this.

[0061] As shown in Figure 2 and Figure 3 , the first mounting member 120 and / or the second mounting member 130 has a third guide slot 132 for the traction rope 360 to pass through.

[0062] The traction rope 360 is arranged in the handle 200, as shown in Figure 4 , and the distal end will enter and connect the active bending segment from the insertion portion 310 to drive the active bending segment to bend. Since the traction rope 360 has small rigidity and long length, it also needs to be guided, and the extension direction of the traction rope 360 is substantially the same as that of the signal line 350. Therefore, the first mounting member 120 and / or the second mounting member 130 is provided with the third guide slot 132 for the traction rope 360 to pass through, so that the third guide slot 132 plays a guiding role for the traction rope 360. And by integrating the third guide slot 132 on the first mounting member 120 and / or the second mounting member 130, there is no need to additionally set a separate traction rope 360 guiding component, further optimizing the structural layout in the handle 200.

[0063] In some embodiments, the first mounting member 120 has a third guide slot 132 for the traction rope 360 to pass through.

[0064] In some embodiments, the second mounting member 130 has a third guide slot 132 for the traction rope 360 to pass through.

[0065] In some embodiments, the first mounting member 120 and the second mounting member 130 respectively have a third guide slot 132 for the traction rope 360 to pass through.

[0066] As shown in Figure 2 , the first guide channel 140 is arranged on the first mounting member 120. By arranging the first guide channel 140 on the first mounting member 120, the first guide channel 140 does not need to occupy additional space in the handle 200, further optimizing the structural layout in the handle 200.

[0067] As shown in Figure 2 , the axis of the distal end of the first guide channel 140 and the axis of the distal end of the second guide channel 150 overlap in the projection direction, so that part of the bottom of the instrument tube 340 can be sunk into the second guide channel 150.

[0068] The axis of the distal end of the first guide channel 140 and the axis of the distal end of the second guide channel 150 overlap in the installation direction, and after the instrument tube 340 is installed in the first guide channel 140, due to the fact that the instrument tube 340 is a circular tube, the bottom of the instrument tube 340 will sink into the second guide channel 150 in the portion where the first guide channel 140 and the second guide channel 150 overlap, so as to reduce the height of the second guide channel 150 in the installation direction, so that the instrument tube 340 can better stop and position the signal line 350 in the second guide channel 150. At the same time, the sinking of the bottom of the instrument tube 340 into the second guide channel 150 can also form a certain constraint on the instrument tube 340 in the width direction.

[0069] The second guide channel 150 is provided with a colloid, which adheres to the signal line 350 and at least part of the instrument tube 340.

[0070] During use, the operator will hold and move the handle 200, so that the orientation and state of the handle 200 change. Due to the small rigidity of the signal line 350, when the handle 200 moves, the signal line 350 is easy to fall out of the second guide channel 150. Therefore, by providing the colloid in the second guide channel 150, the connection strength between the signal line 350 and the second guide channel 150 is increased, and the entanglement or collision of the signal line 350 caused by falling out of the second guide channel 150 is avoided, further ensuring that the data can be smoothly transmitted. Correspondingly, due to the fact that the bottom of part of the instrument tube 340 sinks into the second guide channel 150, the colloid can also fix the instrument tube 340, thereby increasing the connection strength between the installation structure 100 and the instrument tube 340.

[0071] As shown in Figures 1-3 , the first guide channel 140 and the second guide channel 150 are arranged on the intermediate shell 110, and the intermediate shell 110 is arranged in the handle 200. In order to conform to ergonomics, the handle 200 is curved to facilitate the operator to hold. However, the inner wall of the handle 200 is curved, which is not convenient for the arrangement of the first guide channel 140 and the second guide channel 150. Therefore, by arranging the intermediate shell 110, the first guide channel 140 and the second guide channel 150 are arranged on the intermediate shell 110, and then the intermediate shell 110 is installed in the handle 200, so as to reduce the installation difficulty of the first guide channel 140 and the second guide channel 150.

[0072] Specifically, as shown in Figure 5 , Figure 7 and Figure 8As shown, the handle 200 is composed of an upper shell 201 and a lower shell 202, and the intermediate shell 110 is connected with the upper shell 201 or the lower shell 202. In order to facilitate the installation of the intermediate shell 110, the inner wall of the upper shell 201 or the inner wall of the lower shell 202 is provided with a plurality of ribs 204, so that the end surface of the intermediate shell 110 can abut on the plurality of ribs 204, facilitating the stable installation of the intermediate shell 110. The intermediate shell 110 can be fixed on the ribs 204 of the inner wall of the upper shell 201 or the inner wall of the lower shell 202 by means of threaded connection, welding, bonding, clamping and the like, so as to complete the installation of the intermediate shell 110, which is not limited in the embodiment.

[0073] Specifically, the first mounting member 120 and the second mounting member 130 are arranged on the intermediate shell 110 and can be integrally formed with the intermediate shell 110. Correspondingly, the first mounting member 120 and the plurality of second mounting members 130 can also be fixed on the intermediate shell 110 by means of welding, bonding, clamping and the like, which is not limited in the embodiment.

[0074] Correspondingly, as shown in Figure 4 and Figure 5 , the intermediate shell 110 is used for installing not only the instrument tube 340 and the signal line 350, but also the wheel disc 320, the cable 330 and other components.

[0075] As shown in Figure 2 , the distal end of the intermediate shell 110 is provided with a fixing portion 111 for connecting a joint assembly 311 of the insertion portion 310. The insertion portion 310 is an important component for being inserted into the body cavity of a patient, and is connected with the fixing portion 111 at the distal end of the intermediate shell 110 to achieve the fixation of the insertion portion 310. The joint assembly 311 is also connected with the handle 200, that is, any two of the joint assembly 311 of the insertion portion 310, the intermediate shell 110 and the handle 200 are connected with each other, which can further improve the stability of the installation of the intermediate shell 110 and the joint assembly 311 of the insertion portion 310 in the handle 200.

[0076] Specifically, as shown in Figure 6 and Figure 7 , the distal end of the upper shell 201 and the distal end of the lower shell 202 are each provided with a plurality of clamping grooves 203, and the joint assembly 311 of the insertion portion 310 is provided with a clamping portion 312, and the joint assembly 311 of the insertion portion 310 is fixedly connected with the upper shell 201 and the lower shell 202 by means of embedding the clamping portion 312 in the clamping grooves 203.

[0077] As preferred in the embodiment, the joint assembly 311 of the insertion portion 310 and the fixing portion 111 are connected by clamping. Naturally, the joint assembly 311 of the insertion portion 310 and the fixing portion 111 can also be fixed by means of bonding, welding and the like, which is not limited in the embodiment.
