[0002] A spinal puncture positioning table is an auxiliary device specifically designed for spinal puncture surgery, aiming to improve the accuracy and efficiency of puncture. A spinal puncture device is mainly used to collect cerebrospinal fluid for examination to assist doctors in diagnosis and treatment. At the same time, it can also be used for treatment operations such as draining bloody cerebrospinal fluid, reducing intracranial pressure, or injecting drugs into the spinal canal.
[0003] In the prior art, there is an orthopedic spinal puncture locator, including a clamping mechanism, an adjusting block, a second threaded rod, a second turning handle, a third turning handle, a third threaded rod, and a puncture needle perforation. A second fixed frame is arranged inside the first fixed frame, and an adjusting block is arranged inside the second fixed frame. A puncture needle perforation is longitudinally penetrated through the middle of the adjusting block. Through the cooperation of the U-shaped rod, the first threaded rod, the first turning handle, the slider, and the clamping plate in the two clamping mechanisms, by operating the two clamping mechanisms, by rotating the first turning handle to drive the first threaded rod to rotate, through the threaded cooperation between the first threaded rod and the slider, and at the same time through the sliding cooperation between the slider and the U-shaped rod, the rotation of the first threaded rod drives the slider to move, and the slider drives the clamping plate to move closer to the body of the person to be punctured until the two clamping plates are located on both sides of the person's body for clamping, so that the locator is fixedly clamped on the body of the person to be punctured.
[0004] In order to clamp the patient's body, the above-mentioned orthopedic spinal puncture locator is provided with a first threaded rod, a slider, and a clamping plate. However, the above-mentioned orthopedic spinal puncture locator is not provided with a pressure sensor. During the clamping process, without the feedback of the pressure sensor, it will be difficult for medical staff to accurately judge the clamping force of the clamping plate on the patient's body. Over-clamping may cause discomfort or tissue damage to the patient, while under-clamping may affect the accuracy and stability of the puncture. Summary of the Invention

The return spring is compressed and the telescopic rod shrinks until one side of the moving plate contacts the pressure sensor. When the clamping force reaches the threshold preset by the controller, the pressure sensor will send a signal to stop the motor from rotating, thereby accurately controlling the clamping force, improving the patient's comfort, and at the same time reducing the risk of inaccurate puncture positioning or accidental movement of the patient during the operation, effectively improving the accuracy and stability of the puncture and ensuring the safety of the patient.
[0016] 2. The spinal puncture positioning table and the spinal puncture device, by setting the moving rod, fixed rod, fixing bolt and universal wheel, move the moving rod. When the bottom of the first fixing frame contacts the patient, tighten the fixing bolt so that it inserts into the corresponding limit hole of the moving rod, thereby fixing the moving rod to achieve height adjustment of the first fixing frame, providing convenience for the puncture operation of medical staff, improving the practicability of the puncture device. The setting of the universal wheel enables medical staff to quickly move the puncture device, which is not only beneficial to the use of the puncture device, but also can quickly store it after use, achieving the purpose of saving space.

DETAILED DESCRIPTION OF THE INVENTION
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-4 , the present invention discloses a spinal puncture positioning table and a spinal puncture device, including a positioning table body 1. A first fixing frame 201 is arranged above the positioning table body 1. U-shaped rods 202 are fixedly arranged on both sides of the first fixing frame 201. A moving rod 203 is fixedly arranged at the bottom of the end of the U-shaped rod 202 away from the first fixing frame 201. A fixing rod 204 is movably arranged outside the moving rod 203. A threaded hole is opened on one side of the fixing rod 204, and a fixing bolt 205 is movably arranged in the threaded hole. A threaded rod 301 is movably arranged inside the U-shaped rod 202. A slider 302 is movably arranged outside the threaded rod 301. Mounting blocks 303 are fixedly arranged on the opposite sides of the slider 302. Mounting grooves 304 are opened on the opposite sides of the mounting blocks 303. A pressure sensor 305 is fixedly arranged on one side of the inner wall of the mounting groove 304. Chute grooves are opened at the top and bottom of the mounting groove 304, and movable blocks 306 are movably arranged in the chute grooves. The connection relationship between the movable block 306 and the mounting block 303 is a sliding connection. A moving plate 307 is fixedly arranged at one end of the movable block 306. Clamping plates 310 are fixedly arranged on the opposite sides of the moving plate 307. Telescopic rods 308 are fixedly arranged on the upper and lower parts of the other side of the moving plate 307. A return spring 309 is movably arranged outside the telescopic rod 308. The connection relationship between the return spring 309 and the telescopic rod 308 is a sleeved connection. A controller 312 is fixedly arranged on the front surface of the first fixing frame 201.
[0024] Specifically, a limiting hole adapted to the fixing bolt 205 is opened on one side of the moving rod 203. The connection relationship between the fixing bolt 205 and the moving rod 203 is a movable insertion.
[0025] In this embodiment, by setting the moving rod 203 and the fixing bolt 205, a plurality of limiting holes are uniformly arranged along the axial direction of the moving rod 203 to facilitate arbitrary adjustment of the height of the moving rod 203. When one end of the fixing bolt 205 is inserted into the limiting hole, the moving rod 203 is limited, thereby improving the stability of the moving rod 203.
[0026] Specifically, a universal wheel 206 is fixedly arranged at the bottom of the fixing rod 204.
[0027] In this implementation scheme, by setting the universal wheels 206, the setting of the universal wheels 206 enables medical staff to quickly move the puncture device, which is not only beneficial to the use of the puncture device, but also can quickly store it after use, achieving the purpose of saving space.
[0028] Specifically, one end of the threaded rod 301 is fixedly connected to the output shaft of the motor 404.
[0029] In this implementation scheme, by setting the threaded rod 301 and the motor 404, the motor 404 can precisely control the rotation speed and direction, so the threaded rod 301 can also achieve precise rotation control to improve the clamping accuracy.
[0030] Specifically, rubber pads 311 are fixedly arranged on the opposite sides of the clamping plates 310.
[0031] In this implementation scheme, by setting the rubber pads 311, when the clamping plates 310 clamp the patient's body, the rubber pads 311 can reduce the direct pressure and damage to the patient and improve the patient's comfort.
[0032] Specifically, the opposite sides of the clamping plates 310 are both arc-shaped.
[0033] In this implementation scheme, by setting the clamping plates 310 and the rubber pads 311, the arc-shaped clamping plates 310 can better fit the patient's body, which is beneficial to further improving the clamping stability.
[0034] Specifically, a second fixed frame 401 is arranged inside the first fixed frame 201, and an adjusting block 402 is arranged inside the second fixed frame 401.
[0035] In this implementation scheme, by setting the first fixed frame 201, the second fixed frame 401 and the adjusting block 402, when moving the second fixed frame 401, while the second fixed frame 401 moves left and right inside the first fixed frame 201, move the adjusting block 402 back and forth, so as to adjust the position of the puncture needle perforation 403 to make it align with the puncture site of the patient.
[0036] Specifically, a puncture needle perforation 403 is formed in the middle of the adjusting block 402.
[0037] In this implementation scheme, by setting the puncture needle perforation 403, when the puncture needle perforation 403 moves to correspond to the mark on the patient's body, at this time, medical staff can perform a puncture operation on the patient through the puncture needle perforation 403, improving the puncture accuracy.
[0038] During use, medical staff make marks on the body part of the patient to be punctured. The patient lies on the positioning table body 1, and the puncture device is moved using the universal wheels 206. When the first fixing frame 201 is located above the part to be punctured, the fixing bolt 205 is turned. After the restriction on the moving rod 203 is released, the moving rod 203 is moved until the bottom of the first fixing frame 201 fits against the puncture site of the patient. Then the fixing bolt 205 is tightened so that it is inserted into the limit hole of the moving rod 203, thereby fixing the moving rod 203. The motor 404 is started, and the threaded rod 301 begins to rotate. The slider 302 drives the clamping plates 310 to move towards each other. After the clamping plates 310 are closely attached to one side of the patient's body, the threaded rod 301 continues to rotate, and the mounting block 303 moves towards the patient's side, causing the moving plate 307 to move horizontally in cooperation with the movable block 306 and compress the return spring 309. The telescopic rod 308 contracts until one side of the moving plate 307 touches the pressure sensor 305. When the pressure received by the pressure sensor 305 exceeds the threshold set by the controller 312, the pressure sensor 305 will send a signal to the motor 404 to stop its operation, thereby achieving precise control of the clamping force, effectively improving the puncture efficiency and effect. After the puncture device is fixed, the medical staff adjust the positions of the second fixing frame 401 and the adjusting block 402 until the puncture needle perforation 403 is aligned with the marked area of the patient, and then the puncture operation is performed.
[0039] In summary, for the spinal puncture positioning table and the spinal puncture device, by providing the mounting block 303, the mounting groove 304, the pressure sensor 305, the movable block 306, the moving plate 307, the telescopic rod 308, the return spring 309 and the controller 312, the slider 302 drives the clamping plates 310 to move towards each other. After the clamping plates 310 are closely attached to one side of the patient's body, the mounting block 303 continues to move along with the movement of the slider 302, causing the clamping plates 310 to drive the moving plate 307 to move away from the patient. The return spring 309 is compressed and the telescopic rod 308 contracts until one side of the moving plate 307 comes into contact with the pressure sensor 305. When the clamping force reaches the threshold preset by the controller 312, the pressure sensor 305 will send a signal to stop the motor 404 from rotating, thereby accurately controlling the clamping force, improving the patient's comfort, reducing the risk of inaccurate puncture positioning or accidental movement of the patient during the operation, effectively improving the accuracy and stability of the puncture, ensuring the safety of the patient. By providing the moving rod 203, the fixed rod 204, the fixing bolt 205 and the universal wheel 206, when the moving rod 203 is moved and the bottom of the first fixing frame 201 contacts the patient, the fixing bolt 205 is tightened and inserted into the corresponding limit hole of the moving rod 203 to fix the moving rod 203, thereby realizing the height adjustment of the first fixing frame 201, providing convenience for the puncture operation of medical staff and improving the practicability of the puncture device. The setting of the universal wheel 206 enables medical staff to quickly move the puncture device, which is not only beneficial to the use of the puncture device but also allows for quick storage after use, achieving the purpose of saving space.
