Description

Technical Field

[0001] The present invention relates to the field of anesthesia devices, and particularly to an electric stimulation anesthesia puncture device. Background Technique

[0002] Spinal cord electrical stimulation surgery implants electrodes into the spinal canal and stimulates the spinal cord through pulsed current to achieve the effect of disease treatment. Spinal cord electrical stimulation surgery is generally divided into two stages: spinal cord electrical stimulation pre-experiment and permanent implant of the stimulator; in the first stage, it is the pre-experiment stage, that is, first use a local anesthetic in the back area, and then under X-ray fluoroscopy, insert a hollow needle through the skin into the epidural space between the bone and the spinal cord, and then insert and place the test wire in a specific spinal cord segment area. The other end of the motor wire is connected to an external stimulator, and the external stimulator emits pulsed current to let the test wire perform electrode treatment on the patient's spine area. According to the patient's somatosensory perception, it is judged whether the electrical stimulation therapy is effective. If effective, the second-stage surgery can be performed.

[0003] Before the electrode is implanted, it is necessary to inject a local anesthetic into the patient's back area, and during the injection process, it is necessary to ensure that the anesthesia needle passes through between two vertebrae, which requires a very precise injection technique. Generally, the patient lies prone on the operating table, and the anesthesia needle also needs to be at a certain inclination angle to accurately inject the anesthetic between two vertebrae. Moreover, the subsequent hollow needle also enters the patient's body through the injection point of the anesthesia needle and the same travel. If the anesthesia needle is not injected accurately, it will cause the patient to experience pain and discomfort during the operation. It is extremely difficult for a doctor to inject the anesthesia and insert the hollow needle by hand and ensure that the insertion travel and insertion angle of the two are the same, and there is a high risk of deviation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figures 1-4, An electrostimulation anesthesia puncture device shown in the figure includes: an operating table 1 and a rail 2 fixedly installed at the bottom of the operating table 1. The rail 2 is parallel to the operating table 1. A sliding frame block 3 is also slidably assembled inside the rail 2. A first threaded rod is rotatably arranged inside the rail 2, and the sliding frame block 3 is threadedly sleeved outside the first threaded rod. The rotation of the first threaded rod causes the sliding frame block 3 to reciprocate along the rail 2. One end of the rail 2 is fixedly provided with a first motor 4, and the output end of the first motor 4 is fixedly assembled with one end of the first threaded rod through a coupling. Cylinder push rods 5 are provided at both ends of the sliding frame block 3. One end of the cylinder push rod 5 close to the sliding frame block 3 is fixedly provided with an adjustment turntable 6, and a number of first circular holes evenly distributed in a circle are opened inside the adjustment turntable 6. Second circular holes are opened at both ends of the sliding frame block 3. A pin is jointly embedded between the first circular hole and the second circular hole. A rotating shaft is fixedly arranged between the two adjustment turntables 6, and the rotating shaft rotatably penetrates the sliding frame block 3. The output ends of the cylinder push rods 5 face upward, and a hanging rail 7 is fixedly arranged at the common output ends of the two cylinder push rods 5. A sliding hanging frame 8 is slidably assembled at the bottom of the hanging rail 7. One end of the hanging rail 7 is fixedly provided with a second motor 9, and the output end of the second motor 9 is fixedly provided with a second threaded rod. The second threaded rod is rotatably arranged inside the hanging rail 7, and the sliding hanging frame 8 is threadedly sleeved outside the second threaded rod. The rotation of the second threaded rod causes the sliding hanging frame 8 to reciprocate at the bottom of the hanging rail 7. Through the action of the adjustment turntable 6 and the rotating shaft, the inclination states of the two cylinder push rods 5 can be adjusted. Adjusting the inclination states of the cylinder push rods 5 is to adjust the inclination states of the puncture clamping unit. After the adjustment is completed, the positions of the two cylinder push rods 5 can be limited by the fitting of the pin with the first circular hole and the second circular hole; A puncture clamping unit for stably clamping an anesthetic needle and a hollow needle. The puncture clamping unit is located at the bottom of the hanging rail 7.

[0020] The puncture clamping unit includes a hollow frame 15 fixedly arranged at the bottom of the sliding hanger 8. Two moving arms 19 are slidably assembled inside the hollow frame 15, and the two moving arms 19 are symmetrically distributed. An oppositely threaded rod 16 is rotatably arranged inside the hollow frame 15, and the moving arms 19 are threadedly assembled with the oppositely threaded rod 16. The two moving arms 19 are respectively threadedly sleeved on both sides of the oppositely threaded rod 16. Second clamping plates 21 and first clamping plates 20 are respectively fixedly arranged at the bottoms of the two moving arms 19. A hollow groove 22 is formed inside the first clamping plate 20, and the second clamping plate 21 extends into the inside of the hollow groove 22. An anesthetic syringe 10 or a flaring tube 11 is placed at the intersection of the first clamping plate 20 and the second clamping plate 21. A driving component is further arranged outside the oppositely threaded rod 16. The driving component drives the oppositely threaded rod 16 to rotate. Since the two moving arms 19 are respectively threadedly assembled on both sides of the oppositely threaded rod 16, and with the limiting treatment of the hollow frame 15 on the moving arms 19, when the oppositely threaded rod 16 rotates, the two moving arms 19 can move synchronously and in opposite directions.

[0021] The flaring tube 11 is fixedly butted with the inlet end of the hollow needle. The flaring tube 11 has the same outer diameter as the anesthetic syringe 10, and limiting collar rings 12 are fixedly sleeved on the outer surfaces of both the anesthetic syringe 10 and the flaring tube 11. Through the limiting collar rings 12, they can be hung on the upper end surface of the first clamping plate 20, which is convenient for the first clamping plate 20 and the second clamping plate 21 to clamp the anesthetic syringe 10 or the flaring tube 11 during the process of moving towards each other.

[0022] The second clamping plate 21 and the first clamping plate 20 are made of carbon alloy material, and the limiting collar ring 12 is made of hard magnetic material. The limiting collar ring 12 can magnetically attract the first clamping plate 20. When the first clamping plate 20 and the second clamping plate 21 release the anesthetic syringe 10 or the flaring tube 11, due to the magnetic attraction of the limiting collar ring 12 to the first clamping plate 20, it can also ensure that the anesthetic syringe 10 or the flaring tube 11 will not fall off randomly.

[0023] The driving component includes a third motor 13 fixedly installed outside the sliding hanger 8, and a first gear 14 is fixedly arranged at the output end of the third motor 13. A second gear 17 is arranged at one end of the oppositely threaded rod 16, and a transmission belt 18 is transmission-assembled between the first gear 14 and the second gear 17. Circular retaining plates are fixedly arranged on both end faces of the first gear 14 and the second gear 17. The circular retaining plates are used to prevent the transmission belt 18 from falling off. When the third motor 13 drives the first gear 14 to drive the second gear 17 to rotate, the oppositely threaded rod 16 can be rotated inside the hollow frame 15.

[0024] The second gear 17 is fixedly sleeved on the outer surface of the reverse threaded rod 16. The first gear 14 and the second gear 17 are gears or sprockets, and the transmission belt 18 is a synchronous toothed belt or a transmission chain. The assembly accuracy of the gear and the synchronous toothed belt is high, while the assembly of the sprocket and the transmission chain has stronger transmission stability and is more durable. Embodiment 2: Please refer to the appendix Figures 5-7 , this embodiment is a further illustration of the above Embodiment 1. The second gear 17 is rotatably sleeved outside the reverse threaded rod 16, and an elastic pressing member is provided between the reverse threaded rod 16 and the second gear 17. The elastic pressing member includes an annular cavity opened inside the second gear 17. An arc-shaped column 25 is slidably assembled inside the annular cavity, and a connecting rod 24 is fixedly provided between the arc-shaped column 25 and the reverse threaded rod 16. The center of the arc-shaped column 25 coincides with the axis of the reverse threaded rod 16. A connecting plate 23 is fixedly provided inside the annular cavity, and a first spring 26 is fixedly provided between the connecting plate 23 and the end of the arc-shaped column 25 away from each other. The first spring 26 is also arc-shaped. When the second gear 17 in the appendix Figure 5 rotates clockwise, the second gear 17 pushes the arc-shaped column 25 through the connecting plate 23 and the first spring 26, so that the arc-shaped column 25 drives the reverse threaded rod 16 to rotate. When the reverse threaded rod 16 cannot rotate and the second gear 17 continues to rotate, at this time the first spring 26 will be compressed, so that the reverse threaded rod 16 receives an elastic torsional force, thereby ensuring the stability of the clamping of the anesthetic syringe 10 or the flaring tube 11 by the first clamping plate 20 and the second clamping plate 21.

[0025] A clamping component is also provided between the arc-shaped column 25 and the second gear 17. The clamping component includes a plurality of arc-shaped grooves 32 opened on the outer surface of the arc-shaped column 25 and distributed at equal intervals in a circumferential manner. The center of the circumferential array of the plurality of arc-shaped grooves 32 is the axis of the reverse threaded rod 16. A plurality of arc-shaped columns 25 are all located on the side of the second gear 17 away from the hollow frame 15. A limiting sleeve 27 is fixedly provided on the end surface of the second gear 17 away from the hollow frame 15, and a round-top limiting column 30 is slidably provided inside the limiting sleeve 27. The round-top limiting column 30 slidably penetrates through the second gear 17, and the round-top end of the round-top limiting column 30 is also slidably fitted inside the arc-shaped groove 32. A second spring 31 is fixedly provided between the end of the round-top limiting column 30 away from the arc-shaped column 25 and the limiting sleeve 27. The round-top end of the round-top limiting column 30 does not completely extend into the arc-shaped groove 32, and a part of the arc surface is still outside the arc-shaped groove 32. At this time, when the arc-shaped column 25 exerts a certain thrust on the round-top end of the round-top limiting column 30 through the arc-shaped groove 32, the round-top end of the round-top limiting column 30 can be moved out of the arc-shaped groove 32.

[0026] One end of the dome-shaped limiting post 30 away from the arc-shaped post 25 is fixedly provided with a connecting rod 29 that slidably penetrates through the limiting sleeve 27, and the connecting rod 29 is located at the center of the second spring 31. One end of the connecting rod 29 away from the dome-shaped limiting post 30 is fixedly provided with a knocking block 28. Both the limiting sleeve 27 and the knocking block 28 are made of hard materials. When the dome-shaped limiting post 30 extends into the inner part of the arc-shaped groove 32 but does not touch the bottom of the arc-shaped groove 32, at this time, the knocking block 28 has already abutted against the end face of the limiting sleeve 27.

[0027] The elastic stiffness of the second spring 31 is less than that of the first spring 26, which ensures the elastic engagement between the dome-shaped limiting post 30 and the arc-shaped groove 32 without affecting the normal operation of the arc-shaped post 25. Working principle: In this solution, after the patient lies on the operating table 1 face down, the medical staff can adjust the position of the sliding hanger 8 through the first motor 4, the cylinder push rod 5, and the second motor 9. Moreover, under the action of the adjusting turntable 6, the inclination angles of the two cylinder push rods 5 can be correspondingly adjusted. When the medical staff performs local anesthesia on the patient's spine position, the anesthesia syringe 10 is placed between the first clamping plate 20 and the second clamping plate 21. Then, the third motor 13 drives the first gear 14 and the second gear 17 to rotate, so that the two moving arms 19 can move synchronously and in opposite directions, and the first clamping plate 20 and the second clamping plate 21 clamp the anesthesia syringe 10. The temperature of the anesthesia syringe 10 is adjusted through the clamping. Then, under the action of the cylinder push rod 5, the anesthesia syringe 10 is inserted between the two spinal bones of the patient at a certain inclination angle for local anesthesia injection. After the anesthesia injection is completed, the cylinder push rod 5 drives the anesthesia syringe 10 to reset. By the control of the medical staff on the third motor 13, the anesthesia syringe 10 is replaced with the flaring tube 11. The bottom of the flaring tube 11 is a hollow needle. Finally, still under the action of the cylinder push rod 5, the hollow needle penetrates between the two spinal bones of the patient along the same movement trajectory as the anesthesia syringe 10, so as to ensure both the accuracy during injection and the consistency of the anesthesia injection stroke and the hollow needle stroke. After the hollow needle enters the patient's body and stabilizes, at this time, the electrode placement operation can be carried out through the inner diameter of the hollow needle.

[0028] In this solution, it is also considered that if the clamping force of the first clamping plate 20 and the second clamping plate 21 on the anesthesia syringe 10 or the flaring tube 11 is too large, it is easy to cause deformation of the tube walls of both, that is, it will affect the normal use of the anesthesia syringe 10 or the flaring tube 11. And if the clamping force of the first clamping plate 20 and the second clamping plate 21 is too small, the clamping of the anesthesia syringe 10 or the flaring tube 11 is not stable enough. Therefore, in this solution, when the first clamping plate 20 and the second clamping plate 21 clamp the anesthesia syringe 10 or the flaring tube 11, the reverse threaded rod 16 cannot continue to rotate. And at this time, when the second gear 17 continues to rotate, the first spring 26 can be compressed. By applying an elastic force to the arc-shaped column 25 and the reverse threaded rod 16 through the first spring 26, the elastic force can prevent the reverse threaded rod 16 from rotating back, and can also apply an elastic clamping force to the anesthesia syringe 10 or the flaring tube 11 by the first clamping plate 20 and the second clamping plate 21. That is, it can ensure stable clamping of the anesthesia syringe 10 or the flaring tube 11 while not causing deformation of the outer wall of the anesthesia syringe 10 or the flaring tube 11. When the arc-shaped column 25 is stationary and the second gear 17 continues to rotate, the dome-shaped limiting column 30 will move from the previous arc-shaped groove 32 to another arc-shaped groove 32. Since the dome-shaped limiting column 30 is elastically inserted into the arc-shaped groove 32 each time, that is, the insertion speed is relatively fast, the knocking block 28 can knock on the end of the limiting sleeve 27. The sound generated by the knocking can remind the medical staff that the first clamping plate 20 and the second clamping plate 21 are elastically pressing on the anesthesia syringe 10 or the flaring tube 11 at this time. At this time, the third motor 13 can be stopped.
