When the slider is located close to one end of the light-guiding observation rod, the swing arm three is tilted upward away from one end of the swing arm two and close to the light-guiding observation rod.

[0006] Furthermore, an extension platform plate is vertically fixed to one side wall of the mounting platform, an L-shaped block is fixed to the top surface of the extension platform plate away from one end of the mounting platform, one end of the L-shaped block is perpendicular to the extension platform plate, and the other end faces away from the mounting platform, a vertical plate is vertically fixed to the mounting platform, the guide rod is fixed between the vertical plate and the L-shaped block, the corner of the triangular plate is hinged to the side wall of the L-shaped block, the connecting rod 1 is located on the outside of the side of the extension platform plate, and the end of the swing arm 1 is hinged to the inner right angle of the L-shaped block.

[0007] Furthermore, one end of the swing arm three close to the swing arm two is fixedly connected to one side of the swing arm one with a protruding block, and one end of the connecting rod three is hinged to the protruding block.

[0008] Furthermore, the ends of both ends of the guide rod are interference fit with the slider.

[0021] An embodiment of the present application discloses an observation endoscope for assisting spinal surgery. By first placing the various wiring harnesses carried by the endoscope between the extension platform plate 311, the swing arm 1 306, the swing arm 2 307 and the swing arm 3 308, and then moving the slider 303 to one end of the light-guiding observation rod 1, the clamping device 3 will be in a clamping state, so that the wire tubes can be gathered in an orderly manner, reducing the impact of the wire tubes on the endoscope during the operation; by moving the slider 303 to one end of the L-shaped block 312, the clamping device 3 will be in an open state, and the swing arm 1 306, the swing arm 2 307 and the swing arm 3 308 in the clamping device 3 in the open state will be in a nearly horizontal state, and then the endoscope can be adsorbed on an object using the rubber suction cup 4.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 An observation endoscope for assisting spinal surgery includes a light-guiding observation rod 1, a gripping portion 2, and a clamping device 3. The light-guiding observation rod 1 is in the shape of a slender rod and is used to be inserted into the patient's body. The gripping portion 2 is installed at the tail of the light-guiding observation rod 1. The doctor can hold the gripping portion 2 with his hand to operate the light-guiding observation rod 1. The clamping device 3 is installed at the end position of the light-guiding observation rod 1 near one end of the gripping portion 2. The clamping device 3 is used to clamp various wire tubes carried by the endoscope.

[0024] Reference Figure 2 The clamping device 3 includes a mounting platform 301, a guide rod 302, a slider 303, a triangular plate 304, a connecting rod 1 305, a swing arm 1 306, a swing arm 2 307, a swing arm 308, a connecting rod 2 309 and a connecting rod 3 310. The mounting platform 301 is sleeved on the light-guiding observation rod 1, and the mounting platform 301 is located at one end of the light-guiding observation rod 1 close to the gripping portion 2. The mounting platform 301 and the light-guiding observation rod 1 are interference fit. The top of the mounting platform 301 is a plane. The top surface of the mounting platform 301 is vertically fixed with a vertical plate 313. The vertical plate 313 contacts the outer surface of the light-guiding observation rod 1. An extension platform plate 311 is extended from one end of the top surface of the mounting platform 301 away from the vertical plate 313. The extension platform plate 311 is strip-shaped and its width is smaller than the width of the mounting platform 301. The upper surface of the extension platform plate 311 is coplanar with the upper surface of the mounting platform 301. The top surface of the extension platform plate 311 away from one end of the mounting platform 301 is fixed with an L-shaped block 312. One end of the L-shaped block 312 is perpendicular to the extension platform plate 311, and the other end is away from the mounting platform 301.

[0025] Reference Figure 2The guide rod 302 is a round rod, which is fixed between the vertical plate 313 and the L-shaped block 312, and the axis of the guide rod 302 is perpendicular to the axis of the light guide observation rod 1; the slider 303 is slidably mounted on the guide rod 302, and a shift rod 3031 is fixed vertically to the upper surface of the slider 303. The operator can use the shift rod 3031 to move the slider 303. In addition, the ends of both ends of the guide rod 302 are interference fit with the slider 303, so that when the slider 303 moves toward the two ends of the guide rod 302 respectively, the slider 303 can be interference tightened, which can prevent the slider 303 from sliding freely; the triangular plate 304 is an isosceles triangular plate 304, and two triangular plates 304 are provided. The two triangular plates 304 are respectively located on both sides of the L-shaped block 312 away from the end of the extension platform plate 311, and one of the corners of the triangular plate 304 is hinged to the side wall of the L-shaped plate. There are two connecting rods 305, which are located on both sides of the guide rod 302 respectively. One end of the connecting rod 305 is hinged to the side wall of the slider 303, and the other end is hinged to the other corner of the triangular plate 304; the swing arm 1 306 is a strip rod with a rectangular cross-section, and one end of the swing arm 1 306 is hinged to the right angle of the L-shaped block 312 away from the guide rod 302; one end of the swing arm 2 307 is hinged to the end of the swing arm 1 306 away from the L-shaped block 312.

[0026] Reference Figure 2 and Figure 3 , there are two swing arms 308, which are respectively located on both sides of the swing arm 2 307 away from the end of the swing arm 1 306, and the end of the swing arm 308 is hinged to the end of the swing arm 2 307 away from the end of the swing arm 1 306, and the end of the swing arm 308 close to the end of the swing arm 2 307 extends toward the side of the swing arm 1 306 with a protrusion 3081; there are two connecting rods 2 309, which are respectively close to the inner sides of the triangular plates 304 on both sides, one end of the connecting rod 2 309 is hinged to the last corner of the triangular plate 304, and the other end is hinged to the end of the swing arm 2 307 close to the end of the swing arm 1 306. At the end, the straight-line distance between the hinge axis of connecting rod 2 309 and the L-shaped block 312 is smaller than the straight-line distance between the hinge axis between swing arm 1 306 and swing arm 2 307 and the L-shaped block 312; there are two connecting rods 310, and the two connecting rods 310 are respectively located on both sides of swing arm 2 307, one end of connecting rod 310 is hinged to the raised block 3081 of swing arm 308, and the other end is hinged to the outer side wall of swing arm 1 306 near one end of swing arm 2 307, and the hinge axis of connecting rod 310 at one end of swing arm 1 306 is located below the hinge axis of connecting rod 2 309 at one end of swing arm 2 307.

[0027] When the slider 303 moves to one end of the light guide observation rod 1, the clamping device 3 will be in a clamping state (such as Figure 2As shown in FIG3 , in the clamping state, the various wires and tubes carried by the endoscope can be placed between the extension platform plate 311, the swing arm 1 306, the swing arm 2 307 and the swing arm 3 308, so that the wires and tubes can be collected in an orderly manner. When the slider 303 moves to one end of the L-shaped block 312, the clamping device 3 will be in the open state (as shown in FIG3 ). Figure 4 As shown), the swing arm 1 306, the swing arm 2 307 and the swing arm 3 308 in the clamping device 3 in the open state will be in a nearly horizontal state, so that they can be used as insertion rods to be plugged into an object, so that the endoscope can be hung.

[0028] like Figure 4 As shown, a rubber suction cup 4 is fixed to the end of the swing arm three 308 away from one end of the swing arm two 307, and the suction port of the rubber suction cup 4 is directed in the same direction as the length of the swing arm three 308 and away from the end face of the swing arm three 308. When the medical staff does not need to use the endoscope, the rubber suction cup 4 can be used to adsorb the endoscope on an object. The medical staff only needs to apply force to adsorb the endoscope without performing other operations, thereby facilitating the medical staff and also preventing the light-guiding observation rod 1 and the gripping part 2 of the endoscope from contacting other objects, reducing the possibility of contact with bacteria.

[0029] Reference Figure 2 As shown, a curved rubber block 1 51 is fixedly attached to the side wall of the mounting platform 301 facing the first swing arm 306. A curved rubber block 2 52 is fixedly attached to the side wall of the first swing arm 306 facing the third swing arm 308. A curved rubber block 3 53 is fixedly attached to the side wall of the third swing arm 308 facing the first swing arm 306. When the clamping device 3 is in the retracted state, the curved surfaces of the first, second, and third rubber blocks 51, 52, and 53 are located on the same circular ring. Therefore, the use of the curved rubber blocks 1 51, 52, and 53 can reduce scratches on the clamped wire tube. Furthermore, hooks 6 are fixedly attached to the side surfaces of both third swing arms 308 facing away from the first swing arm 306. Items compatible with the endoscope can be hung on the hooks 6, making it easier for medical staff to find them.

[0030] This application can explain its functional principles through the following operation methods:

[0031] When medical staff use the observation endoscope for assisting spinal surgery, they can place the wire tubes in order under the mounting platform 301, and then toggle the lever 3031 to move the lever 3031 to one end of the light guide observation rod 1. During the movement, the swing arm 308 swings downward and moves to the side of the light guide observation rod 1, and finally makes the swing arm 308 tilt upward, so that the clamping device 3 can be folded (as shown in FIG. Figure 2As shown), the various wire tubes carried on the endoscope can be clamped between the extension platform plate 311, the swing arm 1 306, the swing arm 2 307 and the swing arm 3 308, so that the wire tubes can be gathered in an orderly manner and the interference of the wire tubes on the endoscope during the operation can be reduced.

[0032] When medical staff do not need to use the observation endoscope for assisting spinal surgery, they can move the slider 303 to one end of the L-shaped block 312. During the movement, the swing arm three 308 will move to the side away from the light-guiding observation rod 1, and eventually the swing arm one 306, the swing arm two 307 and the swing arm three 308 will be in a nearly horizontal state, so that the clamping device 3 will be in an open state. Then, the rubber suction cup 4 can be used to adsorb the endoscope on other objects, thereby facilitating the placement of the endoscope. It can also prevent the light-guiding observation rod 1 and the gripping part 2 of the endoscope from contacting other objects, reducing unnecessary contact with the endoscope.

[0033] The above is only a preferred specific implementation method of the embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
