DETAILED DESCRIPTION

[0022] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0023] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. 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 generally a category and do not limit 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.

[0024] 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".

[0025] The inventive concept of the present application is described as follows:

[0026] As a medical diagnostic instrument, the insertion tube part of the endoscope can enter the body through a natural orifice or incision of the human body, and the operator adjusts the bending action of the active bending section at the distal end of the insertion tube by controlling the rotation direction and rotation angle of the rotating member on the handle of the endoscope, so as to adjust the action posture of the active bending section at the distal end of the insertion tube.

[0027] Specifically, the rotating member on the handle is connected with the traction wheel inside the handle, and the traction wheel is rotated by the operator during the process of rotating the rotating member, thereby pulling the traction rope to realize the bending action of the active bending section.

[0028] However, in the current endoscope, the traction wheel adopts shaft hole matching during installation, but the shaft hole matching has a problem that there is a tolerance in the production of each element matched by the shaft hole, which makes the traction wheel prone to shaking during rotation, thereby causing poor controllability of the operator. If more precise instruments and more stringent process are used to produce the elements matched by the shaft hole, the cost will be greatly increased.

[0029] The inventor finds that the shaking of the traction wheel during rotation can be avoided or reduced by setting a damping member in the assembled shaft hole, thereby improving the controllability of the operator on the endoscope.

[0030] Therefore, the inventor provides an endoscope, which sets the rotating shaft and the damping member in the installation slot at the same time, sets the size of the slot opening to be larger than the size of the slot bottom in the region where the damping member is arranged in the installation slot, and sets the damping member to abut the rotating shaft between the inner wall of the installation slot and the damping member, so as to eliminate or reduce the shaking of the rotating shaft during rotation by using the damping member.

[0031] The endoscope 1 provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios. Figures 1 to 10 The endoscope 1 provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios.

[0032] Please refer to Figure 1 and Figure 2 The endoscope 1 provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios.

[0033] Specifically, please refer to Figures 3-6 The installation slot 10 can include a first region 110 and a second region 120, and the first region 110 and the second region 120 are communicated. In the second region 120, the size of the slot opening is larger than the size of the slot bottom, that is, in this embodiment, as the damping member 30 gradually penetrates into the second region 120, the frictional force provided by the damping member 30 to the rotating shaft 20 gradually increases, thereby the damping effect provided by the damping member 30 to the rotating shaft 20 gradually increases, thereby the shaking of the rotating shaft 20 during rotation can be eliminated or reduced.

[0034] It should be noted that the embodiments of the present application do not limit the specific structure of the mounting groove 10. For example, in an embodiment, the first region 110 can be provided as a circular cross-section region, which can better adapt to the rotating shaft 20. The second region 120 can be provided as a square cross-section region, which can avoid the rotation of the damping member 30 in the second region 120, thereby affecting the damping effect provided by the damping member 30. The specific form of the mounting groove 10 can be set according to the actual situation, which is not limited here. For the convenience of description, the first region 110 is taken as a circular cross-section region and the second region 120 is taken as a square cross-section region as an example for description.

[0035] Further, in an embodiment, the first region 110 and the second region 120 can partially overlap, that is, the cross-section of the mounting groove 10 can be provided as a square and a circular mutually invading form, which can make the structure of the mounting groove 10 more compact, thereby facilitating the structure of the rotating shaft 20 and the damping member 30 to be more compact, thereby facilitating the use of the damping member 30 to eliminate or reduce the shaking of the rotating shaft 20 during rotation.

[0036] In a more specific embodiment, on the mounting groove 10, the length of the connecting line at the junction of the first region 110 and the second region 120 is less than the diameter of the rotating shaft 20, that is, in this embodiment, when the rotating shaft 20 is installed in the second region 120, the rotating shaft 20 does not fall into the second region 120 and abuts against the inner wall of the second region 120. The foregoing structure can have a limiting effect on the rotating shaft 20, further reducing the displacement of the rotating shaft 20 caused by shaking during rotation.

[0037] In addition, it should be noted that the embodiments of the present application do not limit whether the groove bottom of the mounting groove 10 is through. For example, in an embodiment, the groove bottom of the first region 110 of the mounting groove 10 can be provided as a through structure, and the groove bottom of the second region 120 can be provided as a non-through structure. At this time, the damping member 30 can extend into the mounting groove 10 to a depth of the mounting groove 10. In another embodiment, the groove bottom of the first region 110 of the mounting groove 10 can be provided as a through structure, and the groove bottom of the second region 120 can also be provided as a through structure. At this time, compared with the previous embodiment, the damping member 30 can extend into the mounting groove 10 to a greater depth, thereby improving the damping effect, but there is a risk of the damping member 30 falling off. The specific form can be set according to the actual situation, which is not limited here.

[0038] Please refer again to Figures 2-4In an embodiment, the damping member 30 can include a first structure part 310 and a second structure part 320, the first structure part 310 is inserted into the mounting groove 10, specifically, the second region 120, and the second structure part 320 extends out of the mounting groove 10. The extending direction of the second structure part 320 is not limited in the embodiments of the present application. For example, in an embodiment, the second structure part 320 can extend vertically, that is, the extending direction of the second structure part 320 can be towards the direction away from the first structure part 310. For another example, in another embodiment, the first structure part 310 can extend in a bent manner, that is, the extending direction of the second structure part 320 can be towards the direction of the rotating shaft 20, and at least partially covers the rotating shaft 20, so as to position the rotating shaft 20. In addition, the second structure part 320 can also extend towards the direction of the sidewall of the mounting groove 10, and at least partially covers the sidewall of the mounting groove 10, so as to facilitate the user to find the force point when taking out the damping member 30, and then facilitate the user to take out the damping member 30 from the mounting groove 10, so as to facilitate the replacement of the damping member 30 and the like.

[0039] Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 In an embodiment, the endoscope 1 can further include an adjusting mechanism 40, one end of the adjusting mechanism 40 is connected to the damping member 30, and the other end extends out of the shell 90 of the endoscope 1. The adjusting mechanism 40 can be used to adjust the depth of the damping member 30 in the mounting groove 10. As described above, in the embodiments, since the second region 120 of the mounting groove 10 is set to have a size of the slot larger than that of the slot bottom, the damping effect of the damping member 30 on the rotating shaft 20 can be different due to the different contact degrees between the damping member 30 and the mounting groove 10. When the adjusting mechanism 40 adjusts the depth of the damping member 30 in the mounting groove 10, the contact degree between the damping member 30 and the mounting groove 10 can be adjusted, so as to facilitate different operators to adjust the damping effect of the damping member 30 on the rotating shaft 20 according to their own preferences and habits, and to improve the applicability of the entire endoscope 1.

[0040] Specifically, in the embodiments of the present application, the adjusting mechanism 40 can include an adjusting channel 410, a transmission block 420 and an adjusting member 430. One end of the adjusting channel 410 can be connected to the inside of the shell 90 of the endoscope 1, and the other end can extend towards the direction of the mounting groove 10. The adjusting channel 410 can be used as a movement channel of the transmission block 420, so as to ensure that the transmission block 420 is on the correct movement path.

[0041] The transmission block 420 can be slidingly arranged in the adjusting channel 410 and abut against the damping member 30. The transmission block 420 can be used to push the damping member 30 and drive the damping member 30 to move towards the groove bottom of the mounting groove 10. The embodiments of the present application do not limit the specific connection manner between the transmission block 420 and the damping member 30. For example, in an embodiment, the transmission block 420 can be detachably connected with the damping member 30, so that the user can replace the transmission block 420 or the damping member 30. The embodiments of the present application also do not limit the form of the detachable connection. For example, in an embodiment, the transmission block 420 and the damping member 30 can be connected by screws. In another embodiment, the transmission block 420 and the damping member 30 can also be connected by interference fit, and the like. The specific connection manner can be set according to actual conditions.

[0042] The adjusting member 430 can be connected to the transmission block 420. The adjusting member 430 can extend out of the shell 90 of the endoscope 1. The adjusting member 430 can be used to adjust the pressure between the transmission block 420 and the damping member 30, and further adjust the depth of the damping member 30 in the mounting groove 10 and the contact degree between the damping member 30 and the mounting groove 10. Specifically, when the user needs to increase the damping effect of the damping member 30 on the rotating shaft 20, the transmission block 420 can be driven by the adjusting member 430 to move towards the damping member 30, and the damping member 30 is pushed to move towards the groove bottom of the mounting groove 10. When the user needs to reduce the damping effect of the damping member 30 on the rotating shaft 20, the transmission block 420 can be driven by the adjusting member 430 to move away from the damping member 30, and the damping member 30 is driven to move away from the groove bottom of the mounting groove 10.

[0043] The embodiments of the present application do not limit the specific connection manner between the adjusting member 430 and the transmission block 420. For example, in an embodiment, the adjusting member 430 and the transmission block 420 can be connected by threads. In this way, the adjusting member 430 can not only drive the transmission block 420 to move in the adjusting channel 410, but also lock the transmission block 420 in a specified area in the adjusting channel 410.

[0044] Please refer again to Figure 2 In some embodiments, the endoscope 1 can further include a lever 50. The lever 50 can be connected to the transmission shaft, and the lever 50 can extend out of the shell 90. When the lever 50 is pressed, the rotating shaft 20 can press the damping member 30, so that the damping effect of the damping member 30 on the rotating shaft 20 can be further increased.

[0045] Specifically, in the embodiment, in the cross section of the endoscope 1, the push rod 50, the transmission shaft and the damping member 30 can be located on the same straight line, and the rotating shaft 20 can be located between the push rod 50 and the damping member 30, so that when the push rod 50 is pressed, the rotating shaft 20 can play a role of extruding the damping member 30.

[0046] Further, please refer to Figure 9 and Figure 10 In an embodiment, the endoscope 1 can further include a driving wheel 60 and a driven wheel 70, the driving wheel 60 can be connected with the push rod 50 through the rotating shaft 20, the driving wheel 60 can be rotationally connected with the driven wheel 70, and the driven wheel 70 can be used to connect the traction rope 80. The user can drive the rotating shaft 20 to rotate by pulling the push rod 50, and then drive the driving wheel 60 to rotate, and then drive the driven wheel 70 to rotate, and finally pull the traction rope 80.

[0047] In the embodiment, the multi-wheel transmission mode can be used, so that the operator only needs to rotate a small angle during the control of the rotation of the push rod 50, and the traction rope 80 can pull the driving bending section to rotate a larger angle, thereby improving the convenience of the operator's control.

[0048] Further, in an embodiment, the driven wheel 70 can include a connecting portion 710 and a transmission portion 720, the transmission portion 720 can be engaged with the driving wheel 60, and the connecting portion 710 can be used to connect the traction rope 80, so that the driving wheel 60 and the driven wheel 70 can avoid clamping the traction rope 80 during engagement, thereby facilitating the normal use of the endoscope 1.

[0049] Further, in an embodiment, the diameter of the driving wheel 60 can be greater than the diameter of the transmission portion 720 and less than the diameter of the connecting portion 710, that is, in this embodiment, the use of a large wheel to drive a small wheel can play a labor-saving role, thereby facilitating the improvement of the damping effect, and since the traction rope 80 is connected to the connecting portion 710, and the diameter of the connecting portion 710 is greater than the diameter of the driving wheel 60 and the diameter of the transmission portion 720, so that the traction rope 80 can have a smaller stretching and contracting range during being driven, thereby facilitating the operator to control the rotation of the driving bending section of the endoscope 1 in the patient's body, and avoiding or reducing the possibility of causing harm to the patient's body due to the excessive bending range and speed of the driving bending section of the endoscope 1.

[0050] The endoscope 1 provided by the embodiment of the present application forms the mounting groove 10 in the endoscope 1, and sets the mounting groove 10 to include the first area 110 for mounting the rotating shaft 20 and the second area 120 for mounting the damping member 30, the damping member 30 is used to abut the rotating shaft 20 between the inner wall of the mounting groove 10 and the damping member 30, and sets the second area 120 to be the size of the slot larger than the size of the groove bottom, so that the damping member 30 provides greater damping to the rotating shaft 20 in the process of extending into the groove bottom, and further makes the shaft hole cooperation between the rotating shaft 20 and the mounting groove 10 more closely, avoids or reduces the shaking of the rotating shaft 20 in the working process, and improves the controllability of the endoscope 1 by the operator.

[0051] It should be noted that in this document, the terms "comprise", "comprising", or any other variant thereof are intended to cover non-exclusive inclusions, so that processes, methods, articles, or devices that include a series of elements not only include those elements, but also include other elements not explicitly listed, or include elements inherent to such processes, methods, articles, or devices. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0052] In addition, it should be pointed out that the scope of the method and device in the embodiment of the present application is not limited to performing the functions in the order shown or discussed, but can also include performing the functions in a substantially simultaneous manner or in a reverse order according to the functions involved, for example, the described method can be performed in an order different from the described order, and various steps can also be added, omitted, or combined. In addition, the features described with reference to certain examples can be combined in other examples.
