[0002] The intervertebral foraminal endoscope is similar to a spinal endoscope. It is a tube equipped with a light. It enters the intervertebral foramen from the side or back of the patient's body (either horizontally or obliquely) and performs surgery in the safe working triangle. After the tube mentioned above is positioned, surgical instruments can pass through the tube to enter the lesion site to facilitate the operation.

[0003] During the operation, the position of the tube also needs to be adjusted in position and angle according to the actual situation of the patient.

[0093] Further, the second fixing assembly includes:

[0094] A support plate 27, the support plate 27 is fixed to the top of the fixing seat 20, and a second threaded hole is opened on the side wall of the support plate 27;

[0095] A second screw rod 34, the second screw rod 34 and the second threaded hole are connected by threads;

[0096] A second fixing plate 35, the second fixing plate 35 is rotatably disposed at an end of the second screw rod 34;

[0097] The second rubber plate 36 is fixed to the end of the second fixing plate 35 .

[0098] The guide tube 21 is inserted into the fixing seat 20, and the second screw rod 34 is rotated. The second screw rod 34 moves along the second threaded hole during rotation. The second screw rod 34 drives the second fixing plate 35 and the second rubber plate 36 to move during movement. The guide tube 21 is squeezed by the two second rubber plates 36 to achieve fixation between the guide tube 21 and the fixing seat 20.

[0099] The specific working principle of the guiding and positioning device used with the intervertebral foraminal endoscope of the present invention is as follows:

[0100] When in use, first clamp the mounting seat 1 at the edge of the operating table, then rotate the first screw rod 23, and the first screw rod 23 rises along the first threaded hole during the rotation process, and the first screw rod 23 drives the first fixing plate 24 and the first rubber plate 25 to rise during the rise process, and then cooperate with the mounting seat 1 to squeeze the edge of the operating table to achieve the fixation between the mounting seat 1 and the operating table;

[0101] Then, the guide tube 21 is inserted into the fixing seat 20, and the second screw rod 34 is rotated. The second screw rod 34 moves along the second threaded hole during the rotation, and the second screw rod 34 drives the second fixing plate 35 and the second rubber plate 36 to move during the movement. The guide tube 21 is squeezed by the two second rubber plates 36 to achieve the fixation between the guide tube 21 and the fixing seat 20;

[0102] Next, the limiting plate 3 is pressed downward to stretch the spring 4, so that the limiting rod 7 leaves the first limiting hole 28 on the fixing tube 6, and the fixing rod 8 is inserted into the fixing tube 6, and the first limiting hole 28 and the second limiting hole 29 are aligned, and finally the limiting plate 3 is released, and the limiting plate 3 is lifted up under the action of the spring 4, so that the limiting rod 7 on the limiting plate 3 enters the first limiting hole 28 and the second limiting hole 29, so that the fixing tube 6 and the limiting rod 7 are fixed;

[0103] Then, the switches of the first solenoid valve 16 and the second solenoid valve 18 are turned on, and then the switch of the third solenoid valve 33 is turned on. At this time, the interior of the sleeve 12 is connected to the oil storage box 22 through the first solenoid valve 16, the second solenoid valve 18, the return pipe 17 and the oil delivery pipe 19, so that the hydraulic oil can flow freely in the sleeve 12 and the oil storage box 22. At this time, the horizontal position or the up and down position and the tilt state of the fixed seat 20 are adjusted. In this process, the fixed seat 20 can be adjusted at any position and any angle through the rotation between the first ball 26 and the first ball seat 10, the rotation between the second ball 11 and the second ball seat 14, and the extension and contraction between the sleeve rod 13 and the sleeve 12, so that the guide tube 21 has different positions and angles to facilitate the operation;

[0104] After the adjustment is completed, the switch of the liquid pump is turned on, and the switch of the third solenoid valve 33 is turned off. At this time, when the liquid pump is working, the hydraulic oil and the second solenoid valve 18 are injected into the sleeve 12 through the oil pipe 19, so that the sleeve 12 is completely filled with hydraulic oil. When the space in the sleeve 12 is completely filled with hydraulic oil, the switches of the first solenoid valve 16 and the second solenoid valve 18 are turned off, so that the piston 30 cannot move, thereby realizing the fixation between the sleeve 12 and the sleeve rod 13, and the second connecting plate 15 is fixed by the second connecting plate 15, the first connecting plate 9 and two groups of second ball seats 14, the second sphere 11, the sleeve 12, the sleeve rod 13, the first ball seat 10 and the first sphere 26, thereby realizing the fixation of the fixing seat 20 and the guide tube 21.
