DETAILED DESCRIPTION

[0136] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0137] In the description of this 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 positional relationship indicated by the terms "inside", "outside", "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply 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 this application. In the description of this application, the meaning of "multiple" is two or more, and at least one means one, two or more, 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.

[0138] It should also be noted that in the drawings of the present application, arrows marked with X indicate a first direction X, arrows marked with Y indicate a second direction Y, and arrows marked with Z indicate a third direction. The first direction X, second direction Y, and third direction Z are introduced to more clearly describe the structure and relative positional relationship of the components of the connection device 10 of the embodiment of the present application. It will be understood that the first direction X, second direction Y, and third direction Z are relative directions defined based on the relative positions of the components, rather than absolute directions. When the connection device 10 is actually used, the first direction X, second direction Y, and third direction Z can point to any direction in space, as long as the first direction X, second direction Y, and third direction Z intersect. Preferably, the first direction X, second direction Y, and third direction Z are orthogonal to each other.

[0139] The applicant has noticed that in some endoscopic surgeries, doctors may need to use two endoscopes. For example, in bile duct exploration, doctors may need to use a duodenoscope and a choledoscopic scope at the same time. First, the duodenoscope is used to enter the duodenum, and then the choledoscopic scope is guided by the duodenoscope into the bile duct system. In this way, under the guidance of the endoscope, stones in the bile duct can be directly observed and treated. In these surgical operations, it is obviously inconvenient for doctors to hold two endoscopes at the same time, so they will connect and fix the two endoscopes together for easy one-handed operation. The current connection method is usually to tie the choledoscopic scope and duodenoscope together with a strap, and the tying and disassembly process is inconvenient.

[0140] 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.

[0141] Please also refer to Figures 1 to 20 The connection device 10 provided in an embodiment of the present application includes a body 100 and a connection assembly 130. The body 100 includes a connection portion 110 for connecting to a first endoscope 20. The body 100 has a placement groove 120, and the placement groove 120 is arranged away from the connection portion 110. The placement groove 120 is used to accommodate a second endoscope 30. The connection assembly 130 is arranged on the body 100 and 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, connecting and fixing the first endoscope 20 through its connection portion 110, accommodating the second endoscope 30 through its placement groove 120, and cooperating with the connection assembly 130 to fix the second endoscope 30. In this way, the first endoscope 20 and the second endoscope 30 can be stably connected and fixed together, which is beneficial to improving the quality and efficiency of surgery.

[0142] Please combine Figure 1 、 Figure 7 、 Figure 8 、 Figure 12 as well as Figure 17 In some embodiments, the body 100 is an integrally molded structure, that is, the body 100 is a one-piece structure without any joints. By setting the body 100 as an integrally molded 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.

[0143] The connecting portion 110 can be formed on a side surface of the body 100, and the side surface can be used as a connecting surface 111, which is connected to the first endoscope 20 by gluing, welding, screw fixing, etc., so as to achieve connection and fixation with the first endoscope 20. Figure 8 、 Figure 21 、 Figure 27 、 Figure 29 、 Figure 38 and Figure 40 It can be understood that the connecting portion 110 includes a connecting surface 111 provided on one side of the main body 100. By connecting the connecting surface 111 to the first endoscope 20, the connection and fixation of the connecting device 10 and the first endoscope 20 can be achieved.

[0144] Please also refer to Figure 27 、 Figure 29 、 Figure 38 、 Figure 40 、 Figure 43 and Figure 45 In some embodiments, the connection surface 111 is a plane, and the connection surface 111 is used to at least partially attach to the first endoscope 20 to connect with the first endoscope 20. By setting the connection surface 111 as a plane, a larger contact area is provided for the connection portion 110 and the first endoscope 20, allowing the two to engage better. The planar structure of the connection surface 111 can achieve a tighter connection with the first endoscope 20, helping to improve the stability and rigidity of the connection and reduce operational instability caused by loose connections. In addition, setting the connection surface 111 as a plane can evenly distribute the load, so that the force borne by the connection portion 110 is more uniform, which can improve the durability of the connection device 10, reduce stress concentration caused by uneven loads, and reduce the aging rate of the device. In addition, setting the connection surface 111 as a plane makes the connection between the connection device 10 and the first endoscope 20 easier to disassemble and install, which is more convenient for repair and replacement of parts, can improve maintenance efficiency, and reduce maintenance difficulties caused by complex connection methods. Furthermore, setting the connecting surface 111 as a plane can reduce the occurrence of sterilization dead corners, making it easier to perform thorough cleaning and sterilization, reducing the retention of dirt and pathogens, thereby improving the sterilization effect and enhancing the safety of the operation.

[0145] It should be noted that, in the description of this application, setting the connecting surface 111 as a plane means that the connecting surface 111 is a flat surface, roughly in the shape of a plane. That is to say, the connecting surface 111 can be on a standard geometric plane, or it may not be an absolutely standard plane structure, and it only needs to be approximately a plane structure, and it may have slight curved surface features or slight geometric deformations. When the connecting device 10 is connected to the first endoscope 20, the connecting surface 111 can be partially attached to the surface of the first endoscope 20, or the connecting surface 111 can be attached to the surface of the first endoscope 20 as a whole. Optionally, the connecting surface 111 is used to be at least partially attached to the steering control unit 210 of the first endoscope 20.

[0146] In some embodiments, the flatness of the connecting surface 111 is less than or equal to 2 mm. By controlling the flatness of the connecting surface 111 within the above range, the irregularities of the connecting surface 111 can be effectively reduced. The uneven contact and stress distribution at the connection caused by irregularities are reduced, and the risk of material fatigue and fracture is increased. By controlling the flatness, the connecting surface 111 can be made flatter, reducing irregularities and improving the stability and reliability of the connection. By controlling the flatness of the connecting surface 111 within the above range, it is beneficial to further improve the sealing of the connection between the connecting device 10 and the first endoscope 20, further reduce gaps, and reduce the difficulty of instrument sterilization.

[0147] The flatness of the connecting surface 111 can be measured using a variety of methods. For example, an optical projector can be used to measure flatness. The optical projector projects a projection of the connecting surface 111, and the flatness is measured based on the degree of overlap between the projected image and the template. Another example of flatness measurement is using a plane leveler, a coordinate measuring machine, a surface measuring instrument, or other equipment. The specific method can be selected based on needs and actual circumstances.

[0148] The first direction X is a direction from the seating groove 120 to the connecting portion 110 , and the second direction Y is an extending direction of the seating groove 120 . The first direction X and the second direction Y intersect.

[0149] Please also refer to Figure 30 、 Figure 36 、 Figure 41 、 Figure 44 and Figure 46In some embodiments, the plane defined by the first direction X and the second direction Y is represented by a dotted line, which is a plane parallel to both the first direction X and the second direction Y. An angle α is formed between the connecting surface 111 and the plane defined by the first direction X and the second direction Y, satisfying the following conditions: 20°≤α≤90°. By setting the angle α within the above range, after the first endoscope 20 and the second endoscope 30 are connected, it is helpful to control the orientation of the first endoscope 20 and the second endoscope 30, thereby facilitating the doctor's surgical operation and reducing the difficulty of the surgical operation. Optionally, the angle α can be any angle value among 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, and 90°, or a range of values between any two angle values.

[0150] It should be noted that in the description of this application, when the plane defined by the first direction X and the second direction Y is perpendicular to the connecting surface 111, the angle α is 90°. Depending on the inclination of the connecting surface 111, the angle between the plane defined by the first direction X and the second direction Y and the connecting surface 111 can be a complementary obtuse angle or an acute angle. The angle α defined in this application is the acute angle. A digital model of the connecting device 10 can be established, the plane defined by the first direction X and the second direction Y can be fitted into the model, and the angle α formed between this plane and the plane of the connecting surface 111 can be measured.

[0151] In some embodiments, the connection surface 111 is configured as a plane with a flatness less than or equal to 2 mm, and the angle α between the connection surface 111 and the plane defined by the first direction X and the second direction Y satisfies the following conditions: 20° ≤ α ≤ 90°. Thus, in this embodiment, the connection surface 111 can simultaneously possess the aforementioned features and produce the aforementioned technical effects, which will not be further elaborated herein.

[0152] Please also refer to Figures 27 to 41The main body 100 further includes a holding portion 105, a seating groove 120 disposed in the holding portion 105, a connecting portion 110 located on a side of the holding portion 105 facing away from the seating groove 120, and connected to the holding portion 105. A connecting surface 111 is located on the side of the connecting portion 110 facing away from the holding portion 105. Specifically, the holding portion 105 is the portion of the main body 100 used to connect to the second endoscope 30. The second endoscope 30 can be received within the seating groove 120 on the holding portion 105 and connected to the holding portion 105, thereby being held in place by the holding portion 105. The connecting portion 110 is disposed on a side of the holding portion 105 away from the seating groove 120, with its connecting surface 111 facing away from the holding portion 105. In this embodiment, optionally, the connecting surface 111 can also be a plane, with a flatness less than or equal to 2 mm, and the angle α between the connecting surface 111 and the plane defined by the first direction X and the second direction Y can also satisfy the following: 20°≤α≤90°. In addition, the connecting component 130 can be connected to the connecting portion 110 or the holding portion 105 .

[0153] Optionally, refer again to Figures 27 to 41 The connecting portion 110 may further include a supporting surface 112, which is located on the side of the connecting portion 110 facing away from the retaining portion 105 and protrudes from the connecting surface 111. That is, in the first direction X, the supporting surface 112 is more protruding than the connecting surface 111 and has a larger distance from the retaining portion 105. Figure 27 、 Figure 33 、 Figure 34 、 Figure 37 、 Figure 38 and Figure 42 The connecting surface 111 is used to connect to the steering control unit 210 of the first endoscope 20, and the supporting surface 112 is configured to be in contact with the gripping portion 220 of the first endoscope 20 when the connecting surface 111 is connected to the steering control unit 210. Thus, the connecting portion 110 can match the shape of the first endoscope 20, and when the connecting surface 111 is connected to the steering control unit 210, the supporting surface 112 can be supported on the gripping portion 220, thereby improving the stability of the connection.

[0154] In some embodiments, as Figures 43 to 46 As shown, the surface of the connecting portion 110 disposed on one side of the body 100 is a planar connecting surface 111. This connecting surface 111 can be partially attached to the steering control portion 210, while the other portion contacts the grip portion 220. In other words, in this embodiment, the connecting portion 110 does not need to be provided with the support surface 112 of the previous embodiment. The connecting surface 111 not only serves to connect to the steering control portion 210, but also provides mutual support with the grip portion 220. Alternatively, the connecting surface 111 can be partially attached to the steering control portion 210, while the other portion is disposed toward and does not contact the grip portion 220.

[0155] Please also refer to Figure 28 、 Figure 31 、 Figure 35 、 Figure 39 The retaining portion 105 further includes a groove 122 that communicates with the seating groove 120. The groove 122 is disposed on the inner wall 121 of the seating groove 120. In the first direction X, the connection portion 110 corresponds to the position of the groove 122. The provision of the groove 122 reduces material consumption and weight of the connection device 10, thereby improving operational comfort and reducing costs. The alignment of the groove 122 with the connection portion 110 facilitates injection molding and reduces processing difficulty.

[0156] Please also refer to Figure 32 、 Figure 33 、 Figure 37 、 Figure 42 Optionally, the connecting device 10 further includes a filling portion 190 that fills the groove 122 , thereby increasing the contact area between the retaining portion 105 and the second endoscope 30 and improving the connection stability with the second endoscope 30 .

[0157] Please also refer to Figures 27 to 29 、 Figure 31 、 Figure 35 、 Figures 38 to 40 Optionally, the connecting portion 110 is provided with a mounting hole 113 that passes through the connecting surface 111. The mounting hole 113 is used to pass a fastener 230 through the fastener 230 to connect the connecting portion 110 to the first endoscope 20, so that the connecting surface 111 is attached to the first endoscope 20. The fastener 230 can be a fastening structure such as a screw or bolt. Accordingly, a screw hole can be provided on the first endoscope 20. The fastener 230 passes through the mounting hole 113 and the screw hole to firmly connect the connecting device 10 and the first endoscope 20. Optionally, the mounting hole 113 can be connected to the groove 122, so that the end of the fastener 230 can be accommodated in the groove 122 to avoid interference with the second endoscope 30. Optionally, filling the groove 122 with the filling portion 190 can cover the fastener 230, thereby reducing loosening of the fastener 230 and reducing the impact of the fastener 230 on the second endoscope 30.

[0158] Optionally, the connecting surface 111 is used to be bonded to the first endoscope 20 to be connected to the first endoscope 20. Glue can be provided on the connecting surface 111 so that the connecting surface 111 is bonded to the first endoscope 20 by gluing. Alternatively, as Figure 11 As shown, glue can be provided on the first endoscope 20, and the connecting surface 111 can be bonded to the first endoscope 20 by gluing. This can facilitate the connection and reduce the processing difficulty and material cost.

[0159] In some embodiments, the connecting portion 110 can be a slot or a buckle formed on one side of the main body 100, and a structure that is compatible with the slot or the buckle is provided on the first endoscope 20. By matching and connecting the connecting portion 110 with the compatible structure on the first endoscope 20, the connection and fixation with the first endoscope 20 are achieved.

[0160] For example, see Figure 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 a screw can be used to connect and fix the main body 100 and the first endoscope 20. 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 provided to improve the stability of the connection. For example, they can be provided on the edge of the main body 100 or through the main body 100. In particular, the screw hole can be connected to the installation groove 120, so that a screw can be installed from the installation groove 120 into the screw hole to connect the connecting device 10 and the first endoscope 20.

[0161] The seating 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 configured to be arc-shaped or other concave shapes to enclose the seating groove 120, so that at least a portion of the side surface forms an inner wall 121 of the seating groove 120. The second endoscope 30 can be accommodated in the seating groove 120. By configuring the inner wall 121 of the seating groove 120 to match the shape of the body 300 of the second endoscope 30, the surface of the body 300 of the second endoscope 30 can be aligned with the inner wall 121 of the seating groove 120, so that the second endoscope 30 can be stably accommodated in the seating groove 120.

[0162] 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.

[0163] See also Figure 1In some embodiments, the direction from the seating groove 120 to the connecting portion 110 is a first direction X, and the extending direction of the seating groove 120 is a second direction Y, where the first direction X intersects the second direction Y. The connecting assembly 130 has a first orthographic projection on a plane perpendicular to the first direction X, and the main body 100 has a second orthographic projection on the same plane. At least a portion of the first orthographic projection is located outside the second orthographic projection and to one side of the second orthographic projection along the second direction Y. It should be noted that in the description of this application, a component located to one side of another component along a certain direction means that the component is located at one end of the other component along the certain direction. It should also be noted that this plane is a projection plane. The structure of the connecting device 10 does not directly set this projection plane. When verifying the relative positional relationship between the area where the first orthographic projection and the area where the second orthographic projection are located later, a plane structure perpendicular to the first direction X can be set as a projection plane. When the connecting assembly 130 and the main body 100 are illuminated by light parallel to the first direction X, the projection areas projected on the projection plane are their respective orthographic projections, namely the first orthographic projection and the second orthographic projection.

[0164] Among them, at least a portion of the first orthographic projection is located outside the second orthographic projection, and at least a portion of the first orthographic projection is located on a side of the second orthographic projection along the second direction Y. That is, relative to the body 100, at least a portion of the connecting component 130 is disposed on a side of the body 100 along the second direction Y. Thus, a force acting on the second endoscope 30 on one side of the extending direction of the seating groove 120 can be generated by the connecting component 130, so that the second endoscope 30 can be connected more stably.

[0165] For details, please refer to Figures 1 to 6 In the first embodiment, the connecting assembly 130 includes a hook portion 140. The hook portion 140 is connected to the body 100, with at least a portion of the hook portion 140 located on one side of the body 100 along the second direction Y. The hook portion 140 is used to suspend the second endoscope 30 for connection with the second endoscope 30. Thus, when the second endoscope 30 is accommodated in the seating groove 120, the hook portion 140 can be suspended on the second endoscope 30 to secure the second endoscope 30, ensuring a stable connection with the second endoscope 30 and allowing the second endoscope 30 to be more stably accommodated in the seating groove 120. Furthermore, the orthographic projection of the hook portion 140 on a 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. This allows the hook portion 140 to generate a connecting force on one side of the extending direction of the seating groove 120 (i.e., the second direction Y), thereby ensuring a more secure connection of the second endoscope 30.

[0166] Please also refer to 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 at least partially hang from the jaw boss 310. The jaw boss 310 is a protruding structure provided on the endoscope body 300, which generally protrudes from the body 300 and forms a jaw access opening thereon. During surgery, the surgeon can insert the corresponding surgical instruments through this jaw access opening. In this embodiment, the hook portion 140 is hung on the jaw boss 310. The protruding structure of the jaw boss 310 can be used to support the hook portion 140. The mutual force generated by the hook portion 140 improves the connection stability and further ensures a secure connection between the second endoscope 30 and the connecting device 10.

[0167] For further information, please also refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 21 In the first and fifth embodiments, the hook portion 140 includes an extension arm 141, a buckle 142, and a hanging arm 143. The extension arm 141 is connected to the body 100 and is at least partially located on one side of the body 100 along the second direction Y. The buckle 142 is opposite and spaced from the extension arm 141. The hanging arm 143 is connected between the extension arm 141 and the buckle 142. The hanging arm 143 is configured to contact the top surface 311 of the jaw boss 310. The extension arm 141 and the buckle 142 are configured to contact two mutually opposing side surfaces 312 of the jaw boss 310, respectively, to suspend the hook portion 140 from the jaw boss 310. The two side surfaces 312 are respectively connected to the top surface of the jaw boss 310. In other words, the hook portion 140 is a bent structure, formed by bending to form the extension arm 141, the hanging arm 143, and the buckle 142, which are 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 conjunction 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 surface 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 Figure 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.

[0168] For further information, please refer 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 disposed away from the connecting portion 110 along the first direction X and is intended to be attached to the side of the endoscope 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 is intended to be attached to the side of the jaw boss 310 facing the main body 100. Thus, the extension arm 141 can mate with the endoscope body 300 and the jaw boss 310 of the second endoscope 30 via its first surface 1411 and second surface 1412, thereby achieving a tighter connection between the two and further improving the stability of the connection between the connecting device 10 and the second endoscope 30.

[0169] 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 .

[0170] See also Figures 27 to 37 In various embodiments in which the connecting portion 110 includes the connecting surface 111, the connecting assembly 130 may also include the hook portion 140. It is understood that the hook portion 140 may have the technical features and effects of the hook portion 140 in the aforementioned embodiments, which will not be repeated here.

[0171] See also Figure 25 and Figure 26In the eighth embodiment, the connecting assembly 130 includes a wrapping portion 180, which is connected to the body 100. At least a portion of the wrapping portion 180 is located on one side of the body 100 along the second direction Y, which is the extension direction of the mounting groove 120. The wrapping portion 180 is used to wrap around the second endoscope 30 to connect with the second endoscope 30. It will be understood that in this embodiment, the wrapping portion 180 of the connecting assembly 130 is similar in structure to the hook portion 140 in the above-mentioned embodiment. Both are partially located on one side of the body 100 along the extension direction of the mounting groove 120 and are associated with the second endoscope 30. The difference is that the wrapping portion 180 is wrapped 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 placement groove 120, thereby improving the connection stability between the connecting device 10 and the second endoscope 30.

[0172] In various embodiments in which the connection portion 110 includes the connection surface 111, the connection assembly 130 may also include the winding portion 180. It is understood that the winding portion 180 may have the technical features and effects of the winding portion 180 in the aforementioned embodiments, which will not be repeated here.

[0173] In some embodiments, the direction from the seating groove 120 to the connecting portion 110 is a first direction X, the extending direction of the seating groove 120 is a second direction Y, the body 100 has a third direction Z, and the first direction X, the second direction Y, and the third direction Z intersect with each other; the connecting assembly 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, at least a portion 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. In other words, relative to the body 100, at least a portion of the connecting assembly 130 is disposed on both sides of the body 100 along the third direction Z. Thus, the connecting assembly 130 can generate a connecting force acting on the second endoscope 30 on both sides of the seating groove 120 in the third direction Z, so that the second endoscope 30 can be connected more stably.

[0174] For details, please refer to Figures 7 to 11 and Figure 22 In the second and sixth embodiments, the connecting assembly 130 includes a snap-fit portion 150 , which is connected to a side of the body 100 facing away from the connecting portion 110 and is located on both sides of the seating groove 120 along the third direction Z. The direction from the seating groove 120 to the connecting portion 110 is the first direction X, and the extending direction of the seating groove 120 is the second direction Y. The first direction X, the second direction Y, and the third direction Z intersect with each other.

[0175] The latching portion 150 is configured to latch onto both sides of the second endoscope 30, securing the second endoscope 30 within the receiving slot 120. By providing the latching portions 150 on both sides of the receiving slot 120, the latching portions 150 can be used to latch onto the second endoscope 30 received within the receiving slot 120, effectively confining the second endoscope 30 within the receiving slot 120 and securing it there. This ensures the stability of the connection between the connecting device and the second endoscope 30. Specifically, in the second embodiment, the latching portion 150 includes at least two side wings 151, which are arranged opposite each other along the third direction Z. The at least two side wings 151 are connected to the body 100 and are located on both sides of the receiving slot 120 along the third direction Z. By providing the side wings 151 on both sides of the receiving slot 120, the two side wings 151 can be used to retain the second endoscope 30 within the receiving slot 120, effectively preventing the second endoscope 30 from detaching from the receiving slot 120 during surgery.

[0176] Further, please combine Figures 12 to 16 Similar to the second embodiment, the connecting assembly 130 in the third embodiment also includes a snap-fit portion 150, which also includes at least two side wings 151. However, in the third embodiment, the side wings 151 include a main body 1511 and a rotating body 1512. The main body 1511 is connected to the body 100 and is provided with a mounting groove 1514. The rotating body 1512 is rotatably connected to the main body 1511 and is disposed within the mounting groove 1514. The rotating body 1512 is configured to rotate in contact with the second endoscope 30 to guide the second endoscope 30 into the receiving groove 120. The provision of the rotating body 1512 within the side wings 151 facilitates the insertion and placement of the second endoscope 30 from the snap-fit portion 150 into the receiving groove 120, facilitating the doctor's assembly and disassembly of the connecting device 10 and the second endoscope 30, thereby improving operational efficiency.

[0177] For further information, please refer to Figure 13 In the third embodiment, the rotating body 1512 has a plurality of anti-skid grooves 1513, which are spaced apart along the outer circumference of the rotating body 1512. The anti-skid grooves 1513 are provided on the outer circumference of the rotating body 1512 to improve the roughness of the outer circumference of the rotating body 1512. This allows the rotating body 1512 to contact the second endoscope 30 and rotate as the connecting device 10 and the second endoscope 30 are installed or removed, thereby facilitating smooth assembly and disassembly of the two and improving assembly and disassembly efficiency.

[0178] Furthermore, in the third embodiment, the rotating body 1512 is made of an elastic material. This allows it to elastically deform when squeezed by the second endoscope 30. This prevents excessive squeezing of the second endoscope 30, thereby preventing damage to the second endoscope 30. Furthermore, this elastic deformation allows it to accommodate second endoscopes 30 of varying sizes, improving compatibility with various 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 be made of a rigid material to reduce manufacturing difficulty and cost.

[0179] In some embodiments, a plurality of snap portions 150 are provided and spaced apart along the second direction Y. By providing a plurality of snap portions 150 , the second endoscope 30 can be fixed at different positions along the extending direction of the seating groove 120 , thereby 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 .

[0180] Furthermore, when multiple snap-fit portions 150 are provided, the minimum spacing between at least two side wings 151 of one snap-fit portion 150 is different from the minimum spacing between at least two side wings 151 of another snap-fit portion 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 tightly combined with the connecting device 10, and the connection effect is better. For example Figure 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 it can be connected with the Figure 14 The body 300 of the second endoscope 30 is adapted to a size gradient 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.

[0181] See also Figure 22 In the sixth embodiment, the side edges of the inner wall 121 of the seating groove 120 jointly form a snap-fit portion 150, and the seating groove 120 is located inside the snap-fit portion 150. It should be noted that in this embodiment, the side wings 151 are the side edges of the inner wall 121 of the seating groove 120. In other words, the side wings 151 and the inner wall 121 of the seating groove 120 are integral with each other without a clear dividing line. By configuring the two side edges of the inner wall 121 that are opposite to each other in the third direction Z to be snap-fitted to the two sides of the second endoscope 30, the second endoscope can be fixed in the seating groove 120.

[0182] Further, please combine Figure 22 and Figure 23 The buckle portion 150 has an opening 152 that communicates with the seating groove 120. The buckle portion 150 is also used to insert the second endoscope 30 into the seating groove 120 through the opening 152. That is, an opening 152 that communicates with the seating groove 120 is formed between the two side wings 151 of the buckle portion 150, and the second endoscope 30 can be inserted into the seating groove 120 along the first direction X through the opening 152. In some embodiments, along the third direction Z, the opening has a maximum dimension D, and the portion of the second endoscope 30 inserted into the seating groove 120 has a maximum dimension L, satisfying: D≤L. Therefore, when the second endoscope 30 is inserted into the seating groove 120 from the opening 152, a force is generated on the buckle portion 150, causing its two opposite side wings 151 to elastically deform and separate to both sides, so that the second endoscope 30 can be smoothly inserted into the seating groove 120, facilitating the installation of the second endoscope 30. When the second endoscope 30 is housed 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 confine the second endoscope 30 in the seating groove 120 to prevent it from falling out, thereby ensuring the stability of the connection.

[0183] Please refer again Figure 1 and Figure 6 In the first embodiment, the connecting component 130 may also include a snap portion 150, and the structure and arrangement position of the snap portion 150 may be consistent with the snap portion 150 in the second embodiment, the third embodiment, and the sixth embodiment. That is, the snap portion 150 may be combined with the hook portion 140 to jointly connect the second endoscope 30, achieve multiple connections, and improve the stability of the connection. Of course, as described above, the hook portion 140 and the snap portion 150 may also exist independently in the connecting device 10 in different embodiments. That is, in some embodiments, the connecting component 130 may have a hook portion 140 without a snap portion 150, and in other embodiments, the connecting component 130 may have a snap portion 150 without a hook portion 140.

[0184] Similarly, please refer to Figure 25In the eighth embodiment, the connecting component 130 may also include a snap portion 150, and the structure and arrangement position of the snap portion 150 may be consistent with the snap portion 150 in the second, third, and sixth embodiments. That is, the snap portion 150 may be combined with the winding portion 180 to jointly connect the second endoscope 30, achieve multiple connections, and improve the stability of the connection. Of course, as described above, the winding portion 180 and the snap portion 150 may also exist independently in the connecting device 10 in different embodiments.
