Technical Field
[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to an anesthesia puncture fixation device for pain medicine. Background Art
[0002] Epidural anesthesia puncture is a commonly used treatment method in the pain department. This operation uses epidural puncture to accurately deliver drugs to the vicinity of the lesion site, thereby reducing nerve root inflammation and edema and achieving good analgesic effect.
[0003] When performing anesthesia puncture, medical staff generally hold the puncture needle to operate. During the entire puncture process, the stability of the puncture needle is controlled by the medical staff's hand. However, the hand often shakes and it is difficult to maintain continuous stability, which may cause the puncture needle to move during the puncture, and there is a risk of damaging the patient's important tissues such as nerves or blood vessels, thereby causing additional pain and discomfort to the patient. In addition, during the puncture, medical staff rely on the obvious "feeling of empty space" produced when the puncture needle penetrates the yellow ligament to judge whether the puncture has reached the appropriate depth. Due to certain uncertainties in human judgment, there is a risk that the medical staff will continue the puncture due to negligence after the puncture is completed, which will cause harm to the patient.

[0024] The operating principle of the present invention is now described as follows: When puncture is required, the second servo motor 105 is started by the PLC controller 2, so that the second servo motor 105 controls the worm 104 to rotate, and under the transmission cooperation of the two worm wheels 103, the two bidirectional screws 101 rotate synchronously, so that the two clamping seats 102 are close to each other to clamp and fix the needle handle of the puncture needle 9. After the clamping is in place, the pressure sensor on the clamping seat 102 will feedback the corresponding electrical signal to the PLC controller 2, so that the PLC controller 2 automatically controls the second servo motor 105 to stop, and then the PLC controller 2 controls the two micro air pumps 20 to start, so that the micro air pumps 20 cooperate with the bellows 21 to suck the air in the clamp seat 102 to generate negative pressure. The clamp seat 102 can firmly absorb the needle handle of the puncture needle 9 by using the negative pressure in cooperation with each suction port. After the needle handle of the puncture needle 9 is firmly absorbed and fixed in place, the air pressure sensor in the clamp seat 102 will feed back the corresponding electrical signal to the PLC controller 2, so that the PLC controller 2 automatically shuts down the two air pumps. At this time, the puncture needle 9 is physically clamped and fixed by the two clamp seats 102, and is fixed by negative pressure absorption, which can effectively ensure the stability of the placement of the puncture needle 9.
[0025] After the puncture needle 9 is fixed, each micro laser positioning light 33 is started through the PLC controller 2. Subsequently, the puncture direction and height of the device are adjusted through the cooperation of each self-locking universal wheel 34 and each electric cylinder 3 until the positioning light generated by each micro laser positioning light 33 is irradiated on the patient's required puncture area. After the formed positioning aperture moves to the target area, each electric push rod 35 is controlled to start through the PLC controller 2, so that each electric push rod 35 controls the suction cup 36 to move down a certain distance and engage with the ground according to the preset program to maintain the stability of the entire device. At this time, the puncture end of the puncture needle 9 will be facing the target area that the patient needs to puncture.
[0026] After the puncture needle 9 is positioned, the first servo motor 54, each ultraviolet disinfection lamp 153 and each ultrasonic atomizer 143 are controlled to start through the PLC controller 2. After the first servo motor 54 is started, it will control one of the guide screws 52 to rotate slowly. Under the transmission cooperation of the pulley assembly 53, the two guide screws 52 will rotate synchronously, so that the two sides of the guide slide 6 are synchronously and stably stressed, so that the guide slide 6 drives the puncture needle 9 on the hollow fixed seat 7 to move slowly horizontally. After the puncture needle 9 contacts the puncture area of the patient, due to the resistance of the muscle tissue, the guide slide 6 will squeeze the reset spring 114 during the movement, so that the sensing slide 112 drives the hollow fixed seat 7 to move relatively backward until the sensing slide 112 is against the second limit block 23. At this time, the sensing slide 112 will move away from the sensing area of the proximity switch 113, so that the proximity switch 113 interrupts the electrical signal feedback to the PLC controller 2, indicating that the puncture operation is in progress at this time. The PLC controller 2 will monitor this process. When the yellow ligament is broken and enters the epidural space, that is, when the puncture needle 9 reaches the target area of anesthesia, the resistance encountered by the puncture needle 9 will disappear, and then the reset spring 114 will release energy, so that the sensing slider 112 drives the hollow fixing seat 7 to move back a little distance. This moving distance is within the required depth range of the puncture needle 9. When the sensing slider 112 moves back, it will be in the sensing area of the proximity switch 113. At this time, the proximity switch 113 will feedback an electrical signal to the PLC controller 2, so that after the puncture is in place, the PLC controller 2 The first servo motor 54 is automatically shut down, and at the same time, the electromagnetic sheet 24 on the first limit block 22 is started, so that the electromagnetic sheet 24 is energized to generate magnetism to attract the induction slider 112, lock the hollow fixing seat 7, and then ensure the stability of the puncture needle 9 in the inserted state. Then, the needle core of the puncture needle 9 is removed, and the needle handle port of the puncture needle 9 is connected to the syringe. After confirming that there is no blood or cerebrospinal fluid by withdrawing the syringe, the epidural catheter is inserted through the channel constructed by the puncture needle 9. After the insertion is completed, the anesthetic drug can be delivered through the epidural catheter; During the puncture operation, the mobile control unit 5 cooperates with the guide slide 6 to drive the puncture needle 9. The guide slide 6 will drive the permanent magnetic piston seat 163 to move horizontally through the strong permanent magnetic slider 28 at the bottom. During the movement of the permanent magnetic piston seat 163, the disinfectant will be transported to the annular disinfection chamber 141 through the infusion tube 30. The disinfectant entering the annular disinfection chamber 141 is atomized by the ultrasonic atomizer 143 to form a fine atomized liquid, which is sprayed to the slowly moving puncture needle 9 through each nozzle 142, so that the puncture needle 9 can be disinfected synchronously during the puncture process. At the same time, the irradiation light generated by each ultraviolet disinfection lamp 153 is enhanced by the corresponding focusing lens 27, so that the enhanced sterilization light can act on the slowly moving puncture needle 9, and the auxiliary disinfectant plays a role in further sterilization and disinfection. During the disinfection process, when entering the annular When the disinfectant in the disinfection chamber 141 contains a large amount of undissolved particles, the light from the ultraviolet disinfection lamp 153 acting on the photosensor 154 will become weaker, causing the electrical signal fed back by the photosensor 154 to become weaker. When the average value fed back to the PLC controller 2 by each photosensor 154 is in a smaller range, the PLC controller 2 will increase the working power of each ultrasonic atomizer 143 accordingly according to the preset program, thereby improving the atomization effect of the disinfectant to ensure the spraying effect of the nozzle 142. Later, when the PLC controller 2 controls the first servo motor 54 to reverse, so that the mobile control unit 5 controls the guide slide 6 to move back, the permanent magnetic piston seat 163 will move back synchronously. During the movement back, under the action of the two one-way valves 31, the liquid guide groove 162 will suck the disinfectant in the liquid storage tank 161 through the liquid replenishment tube 29 for automatic liquid replenishment.
