[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] 1-4 , a foraminal endoscopic device with a movable working sleeve includes: a foraminal endoscopic component 10 and a working sleeve 20 connected to the foraminal endoscopic component 10 via a positioning connector 30, wherein the positioning connector 30 enables the working sleeve 20 to be moved in a horizontal direction and enables the working sleeve 20 to be detachably connected to the foraminal endoscopic component 10; the positioning connector 30 includes a guide rod 31 fixed to the working sleeve 20, a mounting seat 32 plugged into the guide rod 31, and a disassembly assembly 33 arranged inside the mounting seat 32; a moving button assembly 34 is installed on the mounting seat 32, and by pressing the button assembly 34, the mounting seat 32 and the guide rod 31 are no longer in conflict with each other, and the working sleeve 20 can be moved along the length direction of the guide rod 31; by pressing the disassembly assembly 33, the mounting seat 32 and the foraminal endoscopic component 10 are no longer in conflict with each other, and the foraminal endoscopic component 10 and the working sleeve 20 are disassembled. The working sleeve 20 has two symmetrically arranged connecting sleeves 21 and a plug socket 22 fixedly attached to its surface near the positioning connector 30. The connecting sleeve 21 is socketed with the guide rod 31. The plug socket 22 contains a ball, a spring placed on the ball, and a bolt inserted into the spring. The plug socket 22 allows the working sleeve 20 to be plugged in.

[0023] Furthermore, the mounting seat 32 is a U-shaped structure, and a spacer block 321 is fixed inside the mounting seat 32. A through hole is provided in the middle portion of the spacer block 321. The mounting seat 32 has two guide rod through holes 322 near the intervertebral foramen mirror 10. A button hole 323 is provided on the side of one guide rod through hole 322. The button hole 323 is connected to the guide rod through hole 322. The mounting seat 32 has a movable through hole 324 provided at the spacer block 321.

[0024] Furthermore, the movable button assembly 34 includes a button plate 341 and a roller 342 that is perpendicular to and fixedly connected to the button plate 341. The roller 342 is located in the button hole 323 and contacts the guide rod 31. When the aperture mirror needs to be moved, the button plate 341 is pressed, causing the roller 342 and the guide rod 31 to move relative to each other. When the button plate 341 is pressed into place, the roller 342 and the guide rod 31 do not contact each other, and the moving working sleeve 20 is adjusted to the desired position of the aperture mirror. When the position adjustment is completed, the button plate 341 is released, and the roller 342 and the guide rod 31 come into contact with each other, preventing the working sleeve 20 from moving.

[0025] Furthermore, the disassembly assembly 33 includes a pressing block 331, a movable pin 332 fixedly connected to the pressing block 331, a vertical movable block 333 matching the movable pin 332, and a transverse block 334 fixedly connected to the vertical movable block 333. A mounting hole is defined on one end face of the transverse block 334, within which a spring 335 is positioned. One end face of the spring 335 abuts against the curved end face 325 of the mounting seat 32. The vertical movable block 333 is located within the movable through-hole 324, and the pressing block 331 is located on the side of the spacer block 321 proximal to the working sleeve 20. The vertical movable block 333 has a tip movable hole defined therein. The tip of the movable pin 332 is a conical structure, and the tip of the movable pin 332 abuts against the edge of the tip movable hole. When the working sleeve 20 needs to be disassembled from the intervertebral foraminal mirror 10, the pressing block 331 is pressed, causing the tip of the movable pin 332 to move into the tip moving hole. Because the tip of the movable pin 332 is a conical structure, the movable pin 332 exerts a force on the vertical movable block 333 in the direction of the movable through hole 324 during movement, causing the vertical movable block 333 to move along the movable through hole 324. At this time, the upper end surface of the vertical movable block 333 is separated from the clamping piece 11, and the working sleeve 20 and the intervertebral foraminal mirror 10 can now be disassembled. When the working sleeve 20 and the intervertebral foraminal mirror 10 are installed, the steps are the same as above. When the pressing block 331 is released, the vertical movable block 333 is automatically reset to contact the clamping piece 11 due to the force of the spring 335.

[0026] Furthermore, a clamping piece 11 is fixedly connected to the intervertebral foraminal mirror component 10 near the vertical moving block 333 , and the clamping piece 11 and the vertical moving block 333 are clamped with each other.

[0027] The number of devices and processing scales described herein are intended to simplify the description of the present invention, and applications, modifications, and variations of the present invention will be apparent to those skilled in the art.

[0028] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
