[0017] The following further describes the detailed implementation manners of the present application with reference to the drawings.

The terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are 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 thus should not be construed as a limitation to the present application.

[0019] As Figures 3 to 6 shown, the snap - locking device 7 for preventing the imaging of the endoscope camera from changing according to the present application includes a first snap - locking body 71 and a second snap - locking body 72 that are used in cooperation and are arranged in mirror symmetry. Both the first snap - locking body 71 and the second snap - locking body 72 are used for snap - locking and positioning on the fixing frame 5 for assembling the camera 6 in the camera handle 3 of the three - dimensional endoscope; the high - definition camera cable 4 led out from the camera 6 is clamped and fixed through the cooperation of the first snap - locking body 71 and the second snap - locking body 72.

[0020] The first buckle body 71 includes a first assembly frame 7101 which is used for clamping onto the fixed frame 5. Specifically, two first clamping claws 71011 are provided at one end of the first assembly frame 7101 for correspondingly clamping onto two first clamping slots 8 arranged on the upper surface of the fixed frame 5. A first clamping block 71012 is provided at the other end of the first assembly frame 7101 for clamping onto the upper part of the side end face of the fixed frame 5. Through the first clamping claws 71011 and the first clamping block 71012, the first assembly frame 7101 can be clamped onto the fixed frame 5 to achieve relative fixation between the two. Such a structural design also facilitates the installation and disassembly of the first assembly frame 7101 and the fixed frame 5. First positioning claws 7102 and second positioning claws 7103 are fixedly connected to the first assembly frame 7101 at intervals. The distance between the first positioning claw 7102 and the second positioning claw 7103 close to the first assembly frame 7101 is smaller, and the distance between the first positioning claw 7102 and the second positioning claw 7103 far from the first assembly frame 7101 is larger, so as to optimize the structure. A first connecting plate 7104 and a second connecting plate 7105 are respectively connected between the first positioning claw 7102 and the second positioning claw 7103. The first connecting plate 7104 and the second connecting plate 7105 are arranged in parallel, and the first connecting plate 7104 is closer to the first assembly frame 7101. The second connecting plate 7105 is located between the ends of the first positioning claw 7102 and the second positioning claw 7103.

[0021] Since the first buckle body 71 and the second buckle body 72 are arranged in mirror symmetry, the second buckle body 72 includes a second assembly frame 7201 which is used for being clamped on the fixed frame 5. Specifically, two second clamping claws are provided at one end of the second assembly frame 7201 for corresponding clamping connection with two second clamping grooves 9 arranged on the lower surface of the fixed frame 5. A second clamping block is provided at the other end of the second assembly frame 7201 for being clamped on the lower part of the side end face of the fixed frame 5. Through the second clamping claws and the second clamping block, the second assembly frame 7201 can be clamped on the fixed frame 5 to realize the relative fixation of the two. Such a structural design also facilitates the installation and disassembly of the second assembly frame 7201 and the fixed frame 5. Third positioning claws 7202 and fourth positioning claws 7203 are fixedly connected to the second assembly frame 7201 at intervals. The distance between the third positioning claw 7202 and the fourth positioning claw 7203 close to the second assembly frame 7201 is smaller, and the distance between the third positioning claw 7202 and the fourth positioning claw 7203 far from the second assembly frame 7201 is larger, so as to optimize the structure. A third connecting plate 7204 and a fourth connecting plate 7205 are respectively connected between the third positioning claw 7202 and the fourth positioning claw 7203. The third connecting plate 7204 and the fourth connecting plate 7205 are arranged in parallel, and the third connecting plate 7204 is closer to the second assembly frame 7201. The fourth connecting plate 7205 is located between the ends of the third positioning claw 7202 and the fourth positioning claw 7203.

[0022] The first connecting plate 7104 and the third connecting plate 7204 are connected together through the cooperation of a set of screws 73 and nuts 74. The setting of this structure can further ensure that the first mounting bracket 7101 and the second mounting bracket 7201 are positioned at the fixed frame 5. The second connecting plate 7105 and the fourth connecting plate 7205 are connected together through the cooperation of another set of screws 73 and nuts 74. Two first positioning grooves 75 are provided at intervals on the second connecting plate 7105, and two corresponding second positioning grooves are provided on the fourth connecting plate 7205. The first positioning grooves 75 and the second positioning grooves are used in cooperation to clamp and fix the high-definition camera cable 4. Through the cooperation of the second connecting plate 7105, the fourth connecting plate 7205, the screws 73, the nuts 74, the first positioning grooves 75, and the second positioning grooves, the high-definition camera cable 4 can be fixed, so that the high-definition camera cable 4 and the buckle device 7 are relatively fixed. Also, since the buckle device 7 and the fixed frame 5 are relatively fixed, the above structure can make the high-definition camera cable 4, the buckle device 7, the fixed frame 5, and the camera 6 form a whole, and there will be no relative displacement between them. Therefore, when dragging the high-definition camera cable 4, the fixed frame 5 and the camera 6 will move synchronously, and the situation where the camera 6 is displaced relative to the fixed frame 5 will not occur.

[0023] In order to optimize the structure, in this embodiment, the first positioning claw 7102 includes a first horizontal portion 71021, a first inclined portion 71022, and a first vertical portion 71023 that are connected in sequence. The first horizontal portion 71021 is also fixedly connected to the first mounting bracket 7101. The second positioning claw 7103 includes a second horizontal portion 71031, a second inclined portion 71032, and a second vertical portion 71033 that are connected in sequence. The second horizontal portion 71031 is also fixedly connected to the first mounting bracket 7101. The first connecting plate 7104 is connected between the first horizontal portion 71021 and the second horizontal portion 71031. The second connecting plate 7105 is connected between the first vertical portion 71023 and the second vertical portion 71033. The inclination directions of the first inclined portion 71022 and the second inclined portion 71032 make the second connecting plate 7105 close to the high-definition camera cable 4.

[0024] The third positioning claw 7202 includes a third horizontal portion, a third inclined portion, and a third vertical portion that are connected in sequence, wherein the third horizontal portion is also fixedly connected to the second mounting bracket 7201. The fourth positioning claw 7203 includes a fourth horizontal portion, a fourth inclined portion, and a fourth vertical portion that are connected in sequence, wherein the fourth horizontal portion is also fixedly connected to the second mounting bracket 7201. The third connecting plate 7204 is connected between the third horizontal portion and the fourth horizontal portion, and the fourth connecting plate 7205 is connected between the third vertical portion and the fourth vertical portion. The inclined directions of the third inclined portion and the fourth inclined portion cause the fourth connecting plate 7205 to approach the high-definition camera cable 4.

[0025] The buckle device for preventing changes in the imaging of an endoscope camera involved in this application can prevent the camera from shifting, and thus can avoid changes in imaging during long-term use of the camera.

[0026] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
