DETAILED DESCRIPTION

[0095] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0096] In the description of the present application, it should be understood that the terms "proximal end" and "distal end" are used as reference objects by the surgical operator (doctor), wherein the "proximal end" is the end of the surgical tool closer to the operator, and the "distal end" is the end farther away from the operator relative to the "proximal end", that is, the end closer to the patient. The orientation or position relationship indicated by the terms "inside", "outside", "upper", "lower", "left", "right", etc. is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, the meaning of "multiple" is two or more, and at least one means one, two or more than two, unless otherwise clearly and specifically defined. "Connection" can be a direct connection, that is, one object is directly connected to another object, or it can be an indirect connection, that is, one object is connected to another object through other objects.

[0097] It should also be noted that in the drawings of the present specification, an arrow marked with X indicates a first direction X, an arrow marked with Y indicates a second direction Y, and an arrow marked with Z indicates a third direction. The first direction X, the second direction Y, and the third direction Z are introduced to more clearly describe the structure of each component and the relative position relationship of the connection device 10 of the embodiment of the present application. It can be understood that the first direction X, the second direction Y, and the third direction Z are relative directions defined based on the relative positions between the components, rather than absolute orientations. When the connection device 10 is actually used, the first direction X, the second direction Y, and the third direction Z can point to any orientation in space, as long as the first direction X, the second direction Y, and the third direction Z intersect. Preferably, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other.

[0098] The applicant noted that in some endoscopic surgeries, the doctor may need to use two endoscopes. For example, in bile duct exploration, the doctor may need to use a duodenoscope and a choledochoscope at the same time. First, the duodenoscope is used to enter the duodenum, and then the choledochoscope is guided by the duodenoscope into the bile duct system. In this way, the stones in the bile duct can be directly observed and treated under the guidance of the endoscope. In these surgical operations, it is obviously inconvenient for the doctor to hold two endoscopes at the same time, so the two endoscopes are connected and fixed together for one-handed operation. The current connection method is usually to tie the choledochoscope and duodenoscope together with a strap, and the tying and disassembly process is inconvenient.

[0099] In view of this, an embodiment of the present application provides a connecting device 10 for attaching two endoscopes, a first endoscope 20 and a second endoscope 30, and can solve at least one of the above-mentioned technical problems.

[0100] Please also read Figures 1 to 20 The connection device 10 provided in the embodiment of the present application includes a body 100 and a connection assembly 130. The body 100 includes a connection portion 110 for connecting a first endoscope 20, and the body 100 has a placement groove 120, and the placement groove 120 is arranged away from the connection portion 110, and the placement groove 120 is used to accommodate a second endoscope 30. The connection assembly 130 is arranged on the body 100, and the connection assembly 130 is used to connect the second endoscope 30 so that the second endoscope 30 can be fixed in the placement groove 120. Thus, the body 100 can be connected between the first endoscope 20 and the second endoscope 30, and the first endoscope 20 is connected and fixed through its connection portion 110, and the second endoscope 30 is accommodated through its placement groove 120, and the second endoscope 30 is fixed in cooperation with the connection assembly 130. Thus, the first endoscope 20 and the second endoscope 30 can be stably connected and fixed together, which is conducive to improving the quality and efficiency of surgery.

[0101] Please combine Figure 1 , Figure 7 , Figure 8 , Fig.12 as well as Fig.17 In some embodiments, the body 100 is an integrally formed structure, that is, the body 100 is an integrally formed structure without any joints. By setting the body 100 as an integrally formed structure, the integrity of the structure is ensured, the stability of the structure is improved, and the stability of the connection between the first endoscope 20 and the second endoscope 30 is improved to a certain extent.

[0102] The connection portion 110 may be formed on a side surface of the body 100, and the side surface may be used as a connection surface, and connected to the first endoscope 20 by gluing, welding, screwing, etc., so as to achieve connection and fixation with the first endoscope 20. Alternatively, the connection portion 110 may be a slot or buckle formed on one side of the body 100, and a structure matching the slot or buckle is provided on the first endoscope 20. By matching and connecting the connection portion 110 with the matching structure on the first endoscope 20, the connection and fixation with the first endoscope 20 is achieved. For example, please refer to Fig.24 In the seventh embodiment provided in the present application, the connecting portion 110 is a screw hole provided on the main body 100, and the main body 100 and the first endoscope 20 can be connected and fixed by screws. The number and position of the screw holes can be specifically set according to actual needs, for example, two or more screw holes can be set to improve the stability of the connection, for example, they can be set at the edge of the main body 100, or set through the main body 100. In particular, the screw hole can be communicated with the placement groove 120, so that a screw can be installed from the placement groove 120 to the screw hole to connect the connecting device 10 and the first endoscope 20.

[0103] The placement groove 120 is formed on another side surface of the body 100, which is opposite to the connecting portion 110. At least a portion of the side surface is constructed in an arc shape or other concave shapes to enclose the placement groove 120, so that at least a portion of the side surface forms an inner wall 121 of the placement groove 120. The second endoscope 30 can be accommodated in the placement groove 120. By setting the inner wall 121 of the placement groove 120 to match the shape of the lens body 300 of the second endoscope 30, the surface of the lens body 300 of the second endoscope 30 can be fitted with the inner wall 121 of the placement groove 120, so that the second endoscope 30 can be stably accommodated in the placement groove 120.

[0104] Furthermore, in some embodiments, the main body 100 and the connecting assembly 130 are an integrally formed structure, which can ensure the structural integrity of the connecting device 10 and improve the stability of the structure, thereby further improving the stability of the connection between the first endoscope 20 and the second endoscope 30.

[0105] See also Figure 1In some embodiments, the direction from the placement groove 120 to the connection part 110 is the first direction X, the extension direction of the placement groove 120 is the second direction Y, and the first direction X intersects with the second direction Y. The connection component 130 has a first orthographic projection on a plane perpendicular to the first direction X, and the body 100 has a second orthographic projection on the plane, and at least part of the first orthographic projection is located outside the second orthographic projection and is located on the side of the second orthographic projection along the second direction Y. It should be noted that in the description of the present application, a component is located on one side of another component along a certain direction, which means that the component is located at one end of the other component along a certain direction. It should also be noted that the plane is a projection plane. In the structure of the connection device 10, the projection plane is not directly set. When the relative position relationship between the area where the first orthographic projection is located and the area where the second orthographic projection is located is subsequently verified, a plane structure perpendicular to the first direction X can be set as a projection plane. The connection component 130 and the body 100 are respectively irradiated with light parallel to the first direction X, and the projection areas projected on the projection plane are their respective orthographic projections, that is, the first orthographic projection and the second orthographic projection.

[0106] Among them, at least part of the first orthographic projection is located outside the second orthographic projection, and at least part of the first orthographic projection is located on one side of the second orthographic projection along the second direction Y. That is to say, relative to the body 100, at least part of the connecting component 130 is arranged on one side of the body 100 along the second direction Y, so that the connecting component 130 can generate a force acting on the second endoscope 30 on one side of the extending direction of the placement groove 120, so that the second endoscope 30 can be connected more stably.

[0107] For details, please refer to Figure 1 to Figure 6 In the first embodiment, the connecting assembly 130 includes a hook portion 140, which is connected to the body 100, and at least part of the hook portion 140 is located on one side of the body 100 along the second direction Y. The hook portion 140 is used to be suspended on the second endoscope 30 to be connected with the second endoscope 30. Therefore, when the second endoscope 30 is accommodated in the placement groove 120, the hook portion 140 can be hung on the second endoscope 30 to hook the second endoscope 30, thereby ensuring the connection stability with the second endoscope 30, so that the second endoscope 30 can be accommodated in the placement groove 120 more stably. In addition, the orthographic projection of the hook portion 140 on the plane perpendicular to the second direction Y is located on one side of the second orthographic projection of the body 100 along the second direction Y, so that the hook portion 140 can generate a connection force on one side of the extension direction of the placement groove 120 (i.e., the second direction Y), so that the second endoscope 30 is connected more stably.

[0108] Please also read Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In the first embodiment, the second endoscope 30 includes a body 300 and a jaw boss 310, and the hook portion 140 is used to be at least partially suspended on the jaw boss 310. The jaw boss 310 is a protruding structure provided on the endoscope body 300, which usually protrudes from the body 300 and has a jaw opening formed thereon. During the operation, the doctor can insert the corresponding surgical instrument through the jaw opening. In this embodiment, the hook portion 140 is suspended on the jaw boss 310, and the protruding structure of the jaw boss 310 can be used to support the hook portion 140, and the connection stability is improved by the mutual force generated, further ensuring that the second endoscope 30 is firmly connected to the connecting device 10.

[0109] For further information, please also refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 and Fig.21 In the first embodiment and the fifth embodiment, the hook part 140 includes an extension arm 141, a buckle ear 142 and a hanging arm 143. The extension arm 141 is connected to the body 100, and at least part of it is located on one side of the body 100 along the second direction Y; the buckle ear 142 is opposite to the extension arm 141 and is arranged at intervals; the hanging arm 143 is connected between the extension arm 141 and the buckle ear 142. Among them, the hanging arm 143 is used to contact the top surface 311 of the jaw boss 310, and the extension arm 141 and the buckle ear 142 are respectively used to contact the two boss side surfaces 312 of the jaw boss 310 that are away from each other, so that the hook part 140 is suspended on the jaw boss 310, wherein the two boss side surfaces 312 are respectively connected to the top surface of the jaw boss 310. In other words, the hook part 140 is a bent structure, and the extension arm 141, the hanging arm 143 and the buckle ear 142 are formed by bending and sequentially connected from the edge of the body 100. The extension arm 141 contacts one side of the jaw boss 310, the buckle ear 142 contacts the other side of the jaw boss 310, and the hanging arm 143 contacts the top surface 311 of the jaw boss 310, so that the top surface 311 can support the connecting device 10. In combination with the placement groove 120, the connection between the connecting device 10 and the second endoscope 30 is more stable. In particular, please refer to Figure 2 In the first embodiment, the hook portion 140 can generate a pulling force on the second endoscope 30 toward the body 100 by contacting the side 312 of the jaw boss 310 away from the body 100 through the buckle ear 142, thereby further improving the stability of the connection between the connecting device 10 and the second endoscope 30. In particular, please refer to Fig.21In the fifth embodiment, the extension arm 141 applies a pulling force to the jaw boss 310 on the side of the jaw boss 310 away from the main body 100, which can also further improve the stability of the connection between the connecting device 10 and the second endoscope 30.

[0110] For further information, please refer again to Figure 1 and Figure 2 In the first embodiment, the extension arm 141 includes a first surface 1411 and a second surface 1412. The first surface 1411 is arranged away from the connecting portion 110 along the first direction X, and the first surface 1411 is used to be attached to the side of the mirror body 300 facing the main body 100; the second surface 1412 is connected to the side of the first surface 1411 away from the main body 100, and the second surface 1412 is used to be attached to the side of the jaw boss 310 facing the main body 100. Therefore, the extension arm 141 can be attached to the mirror body 300 and the jaw boss 310 of the second endoscope 30 through its first surface 1411 and the second surface 1412, so that the connection between the two is tighter, and the stability of the connection between the connecting device 10 and the second endoscope 30 is further improved.

[0111] In some embodiments, the hook portion 140 is wrapped around the jaw boss 310 to generate a mutual force with the jaw boss 310 to improve the connection stability between the connecting device 10 and the second endoscope 30 .

[0112] See also Fig.25 and Fig.26 In the eighth embodiment, the connection assembly 130 includes a winding portion 180, which is connected to the body 100, and at least part of the winding portion 180 is located on one side of the body 100 along the second direction Y, and the second direction Y is the extension direction of the placement groove 120; the winding portion 180 is used to be wound around the second endoscope 30 to connect with the second endoscope 30. It can be understood that in this embodiment, the winding portion 180 of the connection assembly 130 is similar in structure to the hook portion 140 in the above embodiment, and both are partially located on one side of the body 100 along the extension direction of the placement groove 120, and are associated with the second endoscope 30. The difference is that the winding portion 180 is wound around the second endoscope 30 to achieve connection with the second endoscope 30. Specifically, the winding portion 180 can be wound around the body 300 of the second endoscope 30. By winding around the body 300, the connecting component 130 can be stably connected to the second endoscope 30, thereby more stably fixing the second endoscope 30 in the mounting groove 120, thereby improving the connection stability between the connecting device 10 and the second endoscope 30.

[0113] In some embodiments, the direction from the placement groove 120 to the connection portion 110 is the first direction X, the extension direction of the placement groove 120 is the second direction Y, the body 100 has a third direction Z, the first direction X, the second direction Y and the third direction Z intersect each other; the connection component 130 has a first orthographic projection on a plane perpendicular to the first direction X, the body 100 has a second orthographic projection on the plane, at least part of the first orthographic projection is located outside the second orthographic projection, and is evenly distributed on both sides of the second orthographic projection along the third direction Z. That is to say, relative to the body 100, at least part of the connection component 130 is arranged on both sides of the body 100 along the third direction Z, so that the connection component 130 can generate a connection force acting on the second endoscope 30 on both sides of the placement groove 120 in the third direction Z, so that the second endoscope 30 can be connected more stably.

[0114] For details, please refer to Figure 7 to Figure 11 and Fig. 22 In the second embodiment and the sixth embodiment, the connecting assembly 130 includes a buckle portion 150, which is connected to a side of the body 100 away from the connecting portion 110 and is located on both sides of the placement groove 120 along the third direction Z. The direction from the placement groove 120 to the connecting portion 110 is the first direction X, and the extending direction of the placement groove 120 is the second direction Y. The first direction X, the second direction Y and the third direction Z intersect with each other.

[0115] The buckle portion 150 is used to be clamped on both sides of the second endoscope 30 so that the second endoscope 30 can be fixed in the placement groove 120. By arranging the buckle portion 150 on both side edges of the placement groove 120, the second endoscope 30 accommodated in the placement groove 120 is clamped by the buckle portion 150, which can effectively limit the second endoscope 30 in the placement groove 120 to achieve fixation and ensure the connection stability of the connecting device to the second endoscope 30. Specifically, in the second embodiment, the buckle portion 150 includes at least two side wings 151, which are arranged relatively along the third direction Z, and at least two side wings 151 are connected to the body 100 and are respectively located on both side edges of the placement groove 120 along the third direction Z. By arranging the side wings 151 on both sides of the placement groove 120, the second endoscope 30 accommodated in the placement groove 120 can be limited by the two side wings 151, which can effectively prevent the second endoscope 30 from detaching from the placement groove 120 during surgery.

[0116] Further, please combine Figure 12 to Figure 16Similar to the second embodiment, in the third embodiment, the connecting assembly 130 also includes a buckle portion 150, and the buckle portion 150 also includes at least two side wings 151. The difference is that in the third embodiment, the side wing 151 includes a main body 1511 and a rotating body 1512. The main body 1511 is connected to the main body 100, and the main body 1511 is provided with a mounting groove 1514; the rotating body 1512 is rotatably connected to the main body 1511, and the rotating body 1512 is arranged in the mounting groove 1514; the rotating body 1512 is used to contact and rotate with the second endoscope 30 to guide the second endoscope 30 into the placement groove 120. By arranging the rotating body 1512 in the side wing 151 structure, it is convenient for the second endoscope 30 to be embedded and accommodated in the placement groove 120 from the buckle portion 150, so that the doctor can load and unload the connecting device 10 and the second endoscope 30, thereby improving the operation efficiency.

[0117] For further information, please refer again to Fig.13 In the third embodiment, the rotating body 1512 has a plurality of anti-skid grooves 1513, and the plurality of anti-skid grooves 1513 are arranged at intervals along the outer peripheral surface of the rotating body 1512. By arranging the anti-skid grooves 1513 on the outer peripheral surface of the rotating body 1512, the outer peripheral surface roughness of the rotating body 1512 is improved, so that when the connecting device 10 and the second endoscope 30 are installed and removed, the rotating body 1512 contacts with the second endoscope 30 and rotates as it is installed, or rotates as it is removed, so that the two can be smoothly installed and removed, thereby improving the installation and removal efficiency.

[0118] Furthermore, in the third embodiment, the rotating body 1512 is made of an elastic material. Thus, it can produce elastic deformation when squeezed by the second endoscope 30. On the one hand, it will not over-squeeze the second endoscope 30, avoiding squeezing and damaging the second endoscope 30. On the other hand, it can produce elastic deformation to adapt to second endoscopes 30 of different sizes, thereby improving the adaptability of different products. Of course, in some embodiments, the rotating body 1512 may not be provided with the anti-slip groove 1513. Furthermore, the rotating body 1512 may also be made of a rigid material to reduce the difficulty and cost of processing.

[0119] In some embodiments, a plurality of buckle portions 150 are provided and are spaced apart along the second direction Y. By providing a plurality of buckle portions 150 , the second endoscope 30 can be fixed at different positions along the extending direction of the placement groove 120 , further improving the fixing effect of the second endoscope 30 and ensuring the connection effect between the second endoscope 30 and the connecting device 10 .

[0120] Furthermore, when there are multiple buckle parts 150, the minimum spacing between at least two side wings 151 of one buckle part 150 is different from the minimum spacing between at least two side wings 151 of another buckle part 150. This can adapt to the size change of the lens body 300 of the second endoscope 30, so that the lens body 300 of the second endoscope 30 can be more closely combined with the connecting device 10, and the connection effect is better. Fig.12 In the figure, double-arrow dashed lines are used to mark the minimum spacing between the two side wings 151 of the upper and lower buckle parts 150, wherein the minimum spacing between the two side wings 151 of the upper buckle part 150 is L1, and the minimum spacing between the two side wings 151 of the lower buckle part 150 is L2, wherein L1>L2, so that Fig.14 The body 300 of the second endoscope 30 is adapted to a gradual size change design from top to bottom, ensuring that each position of the body 300 can fit with the buckle portion 150 at the corresponding position, thereby improving the connection effect between the connecting device 10 and the second endoscope 30.

[0121] See also Fig. 22 In the sixth embodiment, the edge portions of both sides of the inner wall 121 of the placement groove 120 jointly form a buckle portion 150, and the placement groove 120 is located inside the buckle portion 150. It should be noted that, in this embodiment, the side wing 151 is the side edge of the inner wall 121 of the placement groove 120, that is, the side wing 151 and the inner wall 121 of the placement groove 120 are integrated without a clear dividing line, and the two side edges of the inner wall 121 arranged opposite to each other in the third direction Z are arranged to be able to be snapped onto the two sides of the second endoscope 30, so that the second endoscope can be fixed in the placement groove 120.

[0122] Further, please combine Fig. 22 and Fig.23, the buckle part 150 has an opening 152 connected to the placement groove 120, and the buckle part 150 is also used for the second endoscope 30 to be embedded in the placement groove 120 through the opening 152. That is, an opening 152 connected to the placement groove 120 is formed between the two side wings 151 of the buckle part 150, and the second endoscope 30 can be embedded in the placement groove 120 along the first direction X through the opening 152. In some embodiments, along the third direction Z, the opening has a maximum size D, and the part of the second endoscope 30 embedded in the placement groove 120 has a maximum size L, satisfying: D≤L. Therefore, when the second endoscope 30 is embedded in the placement groove 120 from the opening 152, a force will be generated on the buckle part 150, so that the two opposite side wings 151 are elastically deformed and separated to both sides, and the second endoscope 30 can be smoothly loaded into the placement groove 120, which is convenient for the installation of the second endoscope 30. When the second endoscope 30 is received in the seating groove 120, since the maximum size of the opening 152 of the buckle portion 150 is smaller than or equal to the size of the portion of the second endoscope 30 located in the seating groove 120, the buckle portion 150 can limit the second endoscope 30 in the seating groove 120 to prevent it from falling out, thereby ensuring the stability of the connection.

[0123] Please refer again Figure 1 and Figure 6 In the first embodiment, the connection assembly 130 may also include a buckle portion 150, and the structure and the setting position of the buckle portion 150 may be consistent with the buckle portion 150 in the second embodiment, the third embodiment, and the sixth embodiment. That is, the buckle portion 150 can be combined with the hook portion 140 to jointly connect the second endoscope 30, realize multiple connections, and improve the stability of the connection. Of course, as described above, the hook portion 140 and the buckle portion 150 can also exist independently in the connection device 10 in different embodiments. That is, in some embodiments, the connection assembly 130 may have a hook portion 140 without a buckle portion 150, and in other embodiments, the connection assembly 130 may have a buckle portion 150 without a hook portion 140.

[0124] Similarly, please refer again Fig.25In the eighth embodiment, the connection assembly 130 may also include a buckle portion 150, and the structure and the setting position of the buckle portion 150 may be consistent with the buckle portion 150 in the second embodiment, the third embodiment, and the sixth embodiment. That is, the buckle portion 150 may be combined with the winding portion 180 to jointly connect the second endoscope 30, realize multiple connections, and improve the stability of the connection. Of course, as described above, the winding portion 180 and the buckle portion 150 may also exist independently in the connection device 10 in different embodiments. That is, in some embodiments, the connection assembly 130 may have a winding portion 180 without a buckle portion 150, and in other embodiments, the connection assembly 130 may have a buckle portion 150 without a winding portion 180.

[0125] Please read again Fig.12 and Fig.13 In some embodiments, the connection assembly 130 further includes a protrusion 160, the protrusion 160 is connected to the body 100, and the protrusion 160 is disposed in the placement groove 120, and the protrusion 160 is disposed protruding relative to the inner wall 121 of the placement groove 120; the protrusion 160 is used to contact the second endoscope 30 when the second endoscope 30 is accommodated in the placement groove 120, and the contact surface between the protrusion 160 and the second endoscope 30 is a rough surface 161. By arranging the protrusion 160 in the placement groove 120, the protrusion 160 can contact the second endoscope 30 in the placement groove 120, so as to support the second endoscope 30 and ensure the stability of the second endoscope 30 in the placement groove 120. By setting the contact surface between the protrusion 160 and the second endoscope 30 to be a rough surface 161, the friction force with the second endoscope 30 can be increased, thereby preventing the second endoscope 30 from moving in the mounting groove 120, and further improving its stability.

[0126] Furthermore, in some embodiments, the material of the protrusion 160 is an elastic material. Thus, the protrusion 160 can produce elastic deformation to adapt to the second endoscope 30 of different sizes, avoid excessive squeezing of the second endoscope 30, and also can better fit the body 300 of the second endoscope 30, thereby improving the stability of the connection.

[0127] Furthermore, in some embodiments, a plurality of protrusions 160 are provided and spaced apart along the second direction Y, and the second direction Y is the extension direction of the mounting groove 120. Thus, the lens body 300 of the second endoscope 30 can be supported at different positions along the length direction of the lens body 300, further ensuring the stability of the second endoscope 30 in the mounting groove 120.

[0128] In some embodiments, the direction from the placement groove 120 to the connection portion 110 is the first direction X; the connection component 130 has a first orthographic projection on a plane perpendicular to the first direction X, and the body 100 has a second orthographic projection on the plane, and the first orthographic projection is located within the second orthographic projection. The connection device 10 of this structure is more compact, and the connection component 130 can be arranged in the placement groove 120 to avoid protruding outside the body 100 and causing spatial interference to the first endoscope 20, the second endoscope 30 or other surgical tools.

[0129] For details, please refer to Figures 17 to 20 In some embodiments, the connection assembly 130 includes a bonding portion 170, which is connected to the body 100 and attached to at least a portion of the inner wall 121 of the placement groove 120; the bonding portion 170 is used to bond the second endoscope 30 so that the second endoscope 30 can be fixed in the placement groove 120. By providing the bonding portion 170 on the inner wall 121 of the placement groove 120, the second endoscope 30 can be connected to the inner wall 121 of the placement groove 120 by using the bonding portion 170. On the one hand, the stability of the connection can be guaranteed to prevent the second endoscope 30 from shaking in the placement groove 120; on the other hand, the bonding portion 170 will not protrude outside the contour space range of the body 100, which can avoid spatial interference with other tools in the operation; furthermore, double-sided tape can be used as the bonding portion 170, which has a simple structure, is easy to process and has low cost.

[0130] Furthermore, in some embodiments, a plurality of bonding portions 170 are provided and spaced apart from each other, so that the second endoscope 30 can be bonded at multiple locations on the inner wall 121 of the placement groove 120, further ensuring the stability of the second endoscope 30 in the placement groove 120 and the stability of the connection between the connecting device 10 and the second endoscope 30.
