The perforaminal endoscopic instrument is suitable for any surgical approach, front, back, left, or right. Different approaches have their own advantages, disadvantages and indications, and have the widest range of applications.

[0003] In the prior art, the spinal foraminal endoscope is equipped with an illumination light source, an optical fiber and a cleaning water pipe inside the same tube. Due to the limitation of the surgical channel space, the surgical tool and the spinal intervertebral fusion endoscope must appear alternately in the surgical channel. The operation of the surgical tool in the surgical channel is a blind operation, and the position adjustment is not flexible, which increases the risk of surgical operation. In addition, the length of the endoscope is long, which is inconvenient for the operation. The foraminal endoscope is a reusable instrument. The foraminal endoscope on the market is currently one-piece and cannot be disassembled. It is inconvenient to clean and disinfect, and there may be a risk of incomplete cleaning and disinfection.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] Reference Figure 1-5 , a fixing and adjusting device for a transforaminal endoscope and a positioning sleeve, comprising:

[0035] A first adjusting device 1A, a first fixing component 12 mounted on the first adjusting device 1A, and a connecting component 5 connected to the first adjusting device 1A;

[0036] The connecting assembly 5 is used to connect the working sleeve 4;

[0037] The first adjustment device 1A is used to fix the aperture mirror base 2;

[0038] The first fixing assembly 12 includes a manual wheel 121, an axial moving rod 122 that passes through the middle of the manual wheel 121 and is threadedly connected to the manual wheel 121, a cap plug 123 fixed to the base 11, and a shift rod 124 placed above the cap plug 123. One end of the axial moving rod 122 is located below the end of the shift rod 124 close to the cap plug 123. The axial moving rod 122 moves toward the shift rod 124, thereby driving the shift rod 124 to move in the vertical direction. The axial moving rod 122 includes a rod body, a thread is provided on the middle of the rod body, and a shovel support section is integrally fixed to the end of the rod body close to the shift rod 124. The shovel support section is located at the bottom of the shift rod 124, and the thickness of the shovel support section gradually decreases toward the direction of the shift rod 124. A first spring is sleeved on the shift rod 124, and the shift rod 124 is located in the base 11. The end of the shift rod 124 close to the cap plug 123 is a gyro section. When the aperture mirror needs to be fixed, the manual wheel 121 is rotated counterclockwise, and the axial moving rod 122 moves toward the shift rod 124. Due to the different thicknesses of the axial moving rod 122, when the axial moving rod 122 moves toward the bottom of the rod 124, the axial moving rod 122 generates an upward force on the shift rod 124, so that the shift rod 124 compresses the first spring, and the top of the shift rod 124 contacts the aperture mirror, thereby making the shift rod 124 fix the aperture mirror, so that the aperture mirror will not be displaced. When the position of the aperture mirror needs to be adjusted, the manual wheel 121 is rotated clockwise, and the shovel support section of the axial moving rod 122 gradually withdraws from the bottom of the shift rod 124 until the shovel support section does not contact the shift rod 124. At this time, the first spring turns from a compressed state to a spring-off state, thereby generating a force on the shift rod 124. At this time, the shift rod 124 is separated from the aperture mirror under the force of the first spring, and the position of the aperture mirror can be adjusted.

[0039] The second fixing assembly includes a rotating waist rod 143 threadedly connected to the first adjustment device 1A, a guide rod 51 connected to the working sleeve 4, and a manual dial handle 142 fixedly connected to the rotating waist rod 143. The rotating waist rod 143 matches the guide rod 51. Through the rotation of the rotating waist rod, the rotating waist rod 143 and the guide rod 51 are mutually abutted. Two guide rods 51 are fixedly connected to the working sleeve 4, and the two guide rods 51 are respectively sleeved on the guide hole 141. A threaded hole is provided on the side of the first side wall 114. An arc-shaped block bar is fixedly connected to the upper end of the threaded hole. The arc-shaped block bar is used to limit the rotation of the manual dial handle 142. The rotating waist rod 143 is threadedly connected to the threaded hole. The rotating waist rod 143 includes a threaded section, an intermediate end integrally connected to the threaded section, and a special-shaped section integrally connected to the intermediate end. The intermediate end and the special-shaped section form a waist drum shape, and the connection between the intermediate end and the special-shaped section contacts the guide rod 51. When the working sleeve needs to be moved, the manual handle 142 is rotated counterclockwise to drive the rotating waist rod 143 to move, so that the rotating waist rod 143 does not conflict with the guide rod 51. At this time, the working sleeve is moved to the required position. When the manual handle 142 is rotated clockwise again, the middle end and the special-shaped section form a waist drum shape, so that the rotating waist rod 143 generates a contact force on the guide rod 51, thereby fixing the guide rod 51. Figure 1 As shown, the state shown in the figure is the state of locking the rotating waist bar 143 and the guide rod 51. At this time, the tail of the manual dial handle 142 is facing away from the working sleeve. When the tail of the manual dial handle 142 is facing the direction of the working sleeve, the guide rod 51 can move relative to the guide hole 141. At this time, the rotating waist bar 143 is put into contact with the base at the end surface, so that the manual dial handle 142 will not be loose and swinging.

[0040] The connecting assembly 5 includes a spring 52, a marble 53 and a plug 54. The marble is inserted into an outer diameter groove of the working sleeve 4. Under the action of the spring 53, the working sleeve 4 and the connecting assembly 5 can be quickly installed or removed by plugging and unplugging.

One end of the axial moving rod 122 is located below the end of the shift rod 124 close to the cap plug 123. The axial moving rod 122 moves in the direction of the shift rod 124, thereby driving the shift rod 124 to move in the vertical direction. The axial moving rod 122 includes a rod body, a thread is provided in the middle part of the rod body, and a shovel support section is integrally fixed to the end of the rod body close to the shift rod 124.

A first spring is sleeved on the shift rod 124, and the shift rod 124 is located in the base 11. The end of the shift rod 124 close to the cap plug 123 is a gyro section. Figure 6 As shown, when the aperture mirror needs to be fixed, the manual wheel 121 is rotated counterclockwise, and the axial moving rod 122 moves toward the shift rod 124. Due to the different thicknesses of the axial moving rod 122, when the axial moving rod 122 moves toward the bottom of the rod 124, the axial moving rod 122 generates an upward force on the shift rod 124, so that the shift rod 124 compresses the first spring, and the top of the shift rod 124 contacts the aperture mirror, so that the shift rod 124 fixes the aperture mirror, so that the aperture mirror will not be displaced. When the position of the aperture mirror needs to be adjusted, the manual wheel 121 is rotated clockwise, and the shovel support section of the axial moving rod 122 gradually withdraws from the bottom of the shift rod 124 until the shovel support section does not contact the shift rod 124. At this time, the first spring turns from a compressed state to a spring-off state, thereby generating a force on the shift rod 124. At this time, the shift rod 124 is separated from the aperture mirror under the force of the first spring, and the position of the aperture mirror can be adjusted.

[0049] Through holes are respectively provided on opposite side walls of the rotating wheel section, and the axial moving rod 122 passes through the through holes to move into the through holes. The side of the side strip 116 close to the base 111 is an inclined surface, and the two side strips 116 form a bracket, so that tools can be placed above the two side strips 116; the inclined surfaces of the two side strips 116 form an eight-shaped structure. The upper surface of the hole mirror is also in an eight-shaped structure, so that the hole mirror and the inclined surfaces of the two side strips 116 form an eight-shaped structure to match, so that the hole mirror can be stably placed in the base 11. When the hole mirror is placed in the base 11, the hole mirror can be fixed by the first fixing component 12. The second fixing assembly 13 is located above the base 11, and the second fixing assembly 13 includes a locking cover 131 movably fixed to the base 11 and a locking member 132 for locking the locking cover 131, the locking member 132 is movably fixed to the base 11; the movement of the locking cover 131 is movably connected to the first side wall 114 through a bearing, and a fixing hole 133 is provided on the locking cover 131 near the locking member 132; a rotating shaft fixing block is fixed to the locking member 132, and a rotating shaft is movably connected to the rotating shaft fixing block, and the rotating shaft is fixedly connected to the second side wall 115, and a placement groove is provided on the second side wall 115, one end of the locking member 132 is fixedly connected to a buckle 134, and the other end is fixedly connected to a second spring 136, and one end of the second spring 136 is fixedly connected to the second side wall 115.
