DETAILED DESCRIPTION

[0029] 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.

[0030] As mentioned in the background technology of the present application, the inventors have discovered through research that the existing puncture work for side-lying patients has certain defects. Since the patient is prone to body position deviation when lying on his side, the insertion distance of the puncture needle 20 will deviate, which in turn leads to unsatisfactory puncture effect. Therefore, how to limit the patient's body position and accurately and stably insert the puncture needle 20 into a preset distance is a difficult problem that urgently needs to be solved.

[0031] In order to solve the above-mentioned defects, the present application discloses an orthopedic spinal puncture device with precise distance determination, which can effectively limit the patient's body position by setting a body position limiting component, and accurately and stably insert the puncture needle 20 to a preset distance.

[0032] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 6In an embodiment of the present invention, a precisely distanced orthopedic spinal puncture device comprises a side lying bed 1, both sides of the side lying bed 1 are fixedly connected to a workbench 2, and a rectangular groove 3 is provided in the middle of the top surface of the side lying bed 1, and the bottom end surface of the rectangular groove 3 and the top surfaces of the two workbenches 2 are provided with a body position limiting component; the body position limiting component comprises two strip support plates 4 respectively fixed to the top surfaces of the two workbenches 2, and the top surfaces of the strip support plates 4 are fixedly connected to two parallel beams 5, and two symmetrical splints 8 are movably connected to the two beams 5, and a driving mechanism is provided between the two beams 5 to drive the two splints 8 to move closer or farther from each other, and a limit fine-tuning mechanism is provided at the top of the splint 8; a reserved hole 10 is provided on the side of a splint 8, and a frame 19 is fixedly connected to the outside of the reserved hole 10, and an adjustable puncture needle mechanism is provided in the frame 19. The present application can effectively limit the patient's body position by setting a body position limiting component, and accurately and stably insert the puncture needle 20 into a preset distance.

[0034] In this embodiment: the position-limiting fine-adjusting mechanism specifically includes: a strip-shaped fixing plate 15 fixed on the top of the splint 8, a side of the strip-shaped fixing plate 15 is threadedly connected with a plurality of evenly distributed adjusting screws 17 along its length direction, and each adjusting screw 17 penetrates the strip-shaped fixing plate 15 and is fixedly connected with a holding head 16, and the other side of the strip-shaped fixing plate 15 is fixedly connected with an elastic band 18, and the elastic band 18 is distributed outside a plurality of holding heads 16. Since the patient lies on his side and has a curved body shape, the present application sets a position-limiting fine-adjusting mechanism, which can adjust the extension distance of each holding head 16 by turning the adjusting screw 17, and the holding head 16 extends to push the elastic band 18 into a curved band that matches the patient's body shape, thereby perfectly fitting and limiting the patient's body shape, further limiting the patient's body position, and avoiding inaccurate puncture distance caused by the patient's body position deviation during the puncture process.

[0035] In this embodiment: the driving mechanism specifically includes: two parallel pulleys 11, the pulleys 11 are rotatably connected between the two beams 5, a driving motor 14 is fixedly connected above one of the pulleys 11, and the output shaft at the bottom of the driving motor 14 is fixedly connected to the corresponding pulley 11, the two pulleys 11 are connected through a transmission belt 12, and the two sides of the transmission belt 12 are respectively fixedly connected with a connecting seat 13, and the two connecting seats 13 are respectively fixedly connected to the bottom ends of the two clamps 8, and the top surface of the beam 5 is fixedly connected with two parallel slide rails 6, and each slide rail 6 is movably connected with a slide seat 7 at the top, and the two slide seats 7 are fixedly connected to the bottom ends of the corresponding clamps 8. The driving mechanism can slowly push the two clamps 8 closer to each other from both sides, so that the two clamps 8 clamp the two sides of the side-lying patient, which has a good limiting effect, and the driving device can drive the two clamps 8 to run synchronously at one time, and will not cause discomfort to the patient, which is convenient to use.

[0036] In this embodiment, rubber pads 9 are fixedly connected to opposite sides of the two splints 8. The rubber pads 9 can buffer the squeezing force of the splints 8 on the patient.

[0037] In this embodiment, the height of the workbench 2 is less than that of the side-lying bed 1, the two crossbeams 5 pass over the rectangular slot 3 of the side-lying bed 1, and the height of the top surface of the crossbeam 5 is less than the height of the top opening of the rectangular slot 3. This arrangement ensures that the middle part of the position restriction component will not hit the patient, avoiding discomfort to the patient.

[0038] In this embodiment: the adjustable puncture needle mechanism specifically includes: a lifting plate 22 movably connected to the inside of the frame 19, cylindrical electromagnets 21 are fixedly connected on both sides of the inside of the frame 19, and the cylindrical electromagnet 21 passes through the lifting plate 22, a metal sleeve 23 is embedded in the position of the lifting plate 22 in contact with the cylindrical electromagnet 21, and the cylindrical electromagnet 21 passes through the corresponding metal sleeve 23, a movable rectangular frame 24 is sleeved on the outside of the lifting plate 22, and a support seat 26 is fixedly connected to the top of the rectangular frame 24, a puncture needle 20 is penetrated inside the support seat 26, and a movable limiting diaphragm 28 is sleeved on the outside of the puncture needle 20, and the limiting diaphragm 28 is in interference contact with the puncture needle 20. By setting up an adjustable puncture needle mechanism, after the patient's puncture position is aligned with the reserved hole 10, the position of the puncture needle 20 can be finely adjusted up, down, left and right, and quickly fixed after the position is found, thereby improving the accuracy of the puncture position. The limiting diaphragm 28 can limit the insertion distance of the puncture needle 20 to achieve the effect of precise distance determination.

[0039] In this embodiment, an infrared distance sensor 27 is embedded on one side of the support seat 26 facing the limit film 28, and a sensing film 29 is embedded on one side of the limit film 28 corresponding to the position of the infrared distance sensor 27. The infrared distance sensor 27 is connected to an external display terminal. The coordinated use of the infrared distance sensor 27 and the sensing film 29 can facilitate the staff to quickly know the penetration distance.

[0040] In this embodiment, a fastening pin 25 is threadedly connected to the outer side of the rectangular frame 24, and one end of the fastening pin 25 passes through the rectangular frame 24 and contacts the lifting plate 22. The fastening pin 25 is used to fix the relative position of the rectangular frame 24 and the lifting plate 22.

[0041] The working principle of the present invention is: when in use, first, let the patient lie on his side on the side-lying bed 1. During the process, let the patient move his body so that the puncture position on the patient's body is aligned with the reserved hole 10. Then, the driving mechanism is operated to drive the two splints 8 to approach each other to clamp the patient. The specific process is: the driving motor 14 is operated to drive a pulley 11 to rotate, and then drive another pulley 11 and the transmission belt 12 to rotate. The two connecting seats 13 on the transmission belt 12 follow the movement and approach each other, thereby driving the two splints 8 to approach each other. During the movement of the splint 8, the slide 7 and the slide rail 6 undergo relative displacement to improve stability. Since the patient is lying on his side with a curved body, after the two splints 8 clamp the patient's body from both sides, the patient's body is clamped and fine-tuned through the limit fine-tuning mechanism. The specific process is: turn the adjusting screw 17 to adjust the extension distance of each abutment head 16. The abutment head 16 extends to push the elastic band 18 into a curved band that matches the patient's body shape, thereby perfectly fitting and limiting the patient's body shape, further limiting the patient's position, and avoiding inaccurate puncture distance caused by the patient's position deviation during puncture.

[0042] Then, the medical staff adjusts the position of the puncture needle 20 through the adjustable puncture needle mechanism and aligns the puncture needle 20 with the position to be punctured on the patient's body. The specific process is: first move the lifting plate 22 up and down. During the process, the metal sleeve 23 of the lifting plate 22 is relatively displaced along the cylindrical electromagnet 21. After the puncture needle 20 and the position to be punctured are at the same horizontal height, the cylindrical electromagnet 21 is energized to generate magnetism. At this time, the cylindrical electromagnet 21 is firmly adsorbed with the metal sleeve 23 through the magnetic adsorption force. The height of the lifting plate 22 is fixed. Then, the horizontal position of the rectangular frame 24 is moved. The puncture needle 20 is aligned with the position to be punctured on the patient's body. After the position is determined, the fastening pin 25 is tightened to fix the relative position of the rectangular frame 24 and the lifting plate 22. Finally, the medical staff adjusts the position of the limiting diaphragm 28 on the puncture needle 20 as needed. The spacing between the limiting diaphragm 28 and the support seat 26 is the distance for pushing the puncture needle 20 during subsequent punctures. The medical staff sets it by themselves as needed to achieve the effect of fixed-distance puncture. It should be noted that the limiting diaphragm 28 is in interference contact with the puncture needle 20. Therefore, the limiting diaphragm 28 requires force to move on the puncture needle 20. Subsequently, the medical staff pushes the puncture needle 20 to move. During the process, one end of the puncture needle 20 extends from the reserved hole 10 and pierces the patient's body. As the puncture needle 20 moves, the limiting diaphragm 28 thereon follows the movement, and the infrared ranging sensor 27 detects that the spacing between the distance sensing diaphragm 29 is gradually reduced, and sends the detection result to the external display terminal for the medical staff to view, so as to facilitate the medical staff to understand the penetration depth of the puncture needle 20 in real time. As the limiting diaphragm 28 contacts the support seat 26 and encounters resistance, the medical staff stops the puncture and slowly withdraws the puncture needle 20. The puncture is completed. The entire puncture process is simple and efficient. By limiting the patient's body, determining the position of the puncture needle 20, and real-time grasping and determining the distance of the puncture needle 20, the medical staff is assisted to accurately complete the puncture work. The puncture experience requirements of the medical staff are relatively low, and it is easy to use.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
