Description

Technical Field

[0001] The invention relates to a needle inserter, in particular to an auxiliary needle inserter capable of adjusting angles in three axes. Background Art

[0002] Stress urinary incontinence is a common pelvic floor dysfunction disease, especially more common in women. According to statistics, the distribution of the incidence of stress urinary incontinence in women is bimodal. The age group of 40 to 59 years old and the age group of over 80 years old are the peak incidence of SUI. The incidence rate of young women is between 7.9% and 11.2%, and the incidence rate of those over 65 years old is 36.2%. The average prevalence rate of pregnant women is about 41%, and it is about 38% 8 weeks after delivery. Men's stress urinary incontinence is mainly caused by iatrogenic factors, among which radical prostatectomy and benign prostatic hyperplasia resection are the most common causes. Many elderly patients regard stress urinary incontinence as a manifestation of aging, resulting in a low willingness to seek medical treatment. However, in order to avoid possible urinary incontinence, they often restrict daily activities such as exercise, sexual life and social activities. Severe patients may also limit their water intake. Long-term activity restrictions will lead to a reduction in the patient's social circle and an increase in negative psychological emotions, which seriously affects the patient's quality of life. Therefore, urinary incontinence is also called social cancer;

[0003] The treatment of stress urinary incontinence with the four sacral acupoints is an innovative acupuncture therapy. Based on modern anatomical and electrophysiological knowledge, it directly stimulates the pudendal nerve and pelvic floor muscles through specific acupuncture directions and depths, and then improves the clinical efficacy through the low-frequency pulse electrical stimulation given by the electroacupuncture instrument. The acupuncture method of the four sacral acupoints adopts the awn needle deep puncture method, and a long needle with a length of 100-125mm is used for acupuncture, which can reach the pudendal nerve and the levator ani muscles, directly stimulate the nerves and the muscles they control, and directly excite the nerves through intermittent wave stimulation of electroacupuncture, induce rhythmic contraction of the pelvic floor muscles, and achieve the purpose of muscle training, thereby regulating the urethral closure pressure, improving urinary control ability, and relieving the symptoms of stress urinary incontinence. At the same time, electroacupuncture can also excite the afferent fibers of the nerves, and inhibit the urination reflex at the central level through the negative feedback regulation mechanism;

[0004] In the prior art, acupuncture treatment is achieved by manual needle insertion, which places high technical requirements on the operator and is prone to inaccurate needle insertion angles and depths, resulting in reduced treatment effects. In view of this, an auxiliary needle insertion device with three-axis adjustable angles is proposed. Summary of the invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention provides a screw rod 1 on the mounting frame to be connected with the adjustment mechanism. When using the device to assist the physician in performing electroacupuncture, the user can place the mounting frame on the treatment bed surface, and then the user can rotate the screw rod 1 according to the height of the needle insertion site of the patient's body shape. When the screw rod 1 rotates, it drives the lifting plate, the adjustment mechanism, the needle feeding mechanism and the kneading mechanism to move up and down through the threaded hole 4 to adjust the height of the needle body, so that the needle body corresponds to the height of the patient's needle insertion site, and the physician can use the adjustment mechanism to adjust the angle of the needle body according to actual treatment needs. At this time, the user can rotate the worm and use the worm gear to drive the rotating shaft 1 and the fixed frame, the needle feeding mechanism and the kneading mechanism to swing back and forth to adjust the angle of the needle body in the vertical direction. At the same time, the user can rotate the limit screw to disengage the slide bar 1, and then pull the fixed plate 4 to rotate along the rotating shaft 2 to swing the needle body in the horizontal direction to adjust its horizontal angle, so that the physician can adjust the needle insertion angle accordingly according to actual treatment needs, further improving the applicability of the device.

[0024] 2. The present invention connects the needle feeding mechanism with the twisting mechanism. When using the device to assist the doctor in performing the needle insertion operation, the adjustment mechanism can be used to adjust the needle body to a suitable angle, and then the limit rod is pulled upward to disengage the limit rod from the limit hole 1 and the limit hole 2, and the fixing frame 2 is pulled to the left to make the fixing plate 6 slide to the left along the sliding rod 2 to squeeze the spring. When the indicator plate 3 corresponds to the starting scale line of the scale plate 2, the pulling of the fixing frame 2 is stopped. At this time, the pushing device brings the tip of the needle body into contact with the needle insertion site of the patient, and then the fixing frame 2 is released to use the spring elastic force to push the fixing frame 2, the twisting mechanism and the needle body to move quickly to the right, so that the tip of the needle body quickly penetrates the patient's skin, thereby reducing the patient's pain and improving the comfort of treatment.

[0025] 3. The present invention connects the needle feeding mechanism with the kneading mechanism. After the needle body is pierced through the patient's skin by the spring force, the user can control the motor 1 to drive the screw 2 to rotate through the controller. When the screw 2 rotates, it drives the connecting plate, the kneading mechanism and the needle body to move right through the threaded hole 2 and continue to penetrate into the patient's body. In this process, the speed of the needle insertion can be controlled by adjusting the rotation speed of the motor 1, so that the doctor can accurately control the speed of the needle insertion to reduce the patient's discomfort caused by the excessively fast needle insertion speed. In addition, during the insertion process, the numerical values ​​corresponding to the indicator plate 3 and the scale plate 2 can be observed to judge the needle insertion depth, so that the doctor can accurately control the needle insertion depth to improve the treatment effect.

[0026] 4. The present invention sets a twisting mechanism connected to the needle body. When the needle body is inserted into the patient's body by the needle feeding mechanism, the user can control the operation of motor 2 through the controller. When motor 2 is working, it drives the turntable to rotate, and uses the fixed rod and the connecting frame to drive the tooth plate to move back and forth. When the tooth plate moves back and forth, the mounting shaft is driven to rotate back and forth in a small range through the gear, so as to simulate the twisting technique of the awn acupuncture method by the rotation of the mounting shaft, and then the needle body is twisted by the twisting mechanism while the needle is inserted, thereby further increasing the functionality of the device and improving the treatment effect.

[0027] 5. The present invention provides an installation cavity and a socket for plugging the needle body in the installation shaft, and arranges a splint in contact with the needle body to clamp and fix the needle body. After completing the treatment, the user can rotate the lead screw and use the transmission of the two sprockets to drive the two lead screws to rotate synchronously. At this time, the rotation of the lead screw drives the two splints to move away from each other and detach from the needle body. At this time, the user can pull the used needle body out of the socket to replace the treatment needle, and then disassemble and assemble the treatment needle as a disposable item to avoid cross infection between patients, or disassemble the non-disposable needle body used for additional disinfection, and also disinfect the related fixing structure of the needle body to ensure the sterility of the needle body.

[0053] An installation cavity 720 is provided inside the right side of the installation shaft 77, and a plug hole 722 is provided at the right end of the installation cavity 720 and is connected to the right side of the installation shaft 77. The installation cavity 720 and the plug hole 722 are both sleeved with the needle handle of the needle body 78, and the needle handle of the needle body 78 is overlapped with the opposite surfaces of the two clamping plates 76 at the same time. The two clamping plates 76 are respectively sleeved in two connecting grooves 721. The two connecting grooves 721 are respectively provided at the upper and lower ends of the installation cavity 720 and are both connected to the outer side of the installation shaft 77. Before using the device for auxiliary treatment, use The needle handle of the needle body 78 can be inserted into the insertion hole 722 and the installation cavity 720, and then the lead screw 75 on one side is rotated to drive the lead screw 75 on the other side to rotate synchronously through the transmission of the two sprocket wheels 1 718. When the lead screw 75 rotates, the two clamping plates 76 are driven to move relatively toward the needle handle through the threaded hole 3 719. When the two clamping plates 76 are in close contact with the needle handle, the needle body 78 is clamped and fixed, so that the needle body 78 is installed and connected with the kneading mechanism 7, so that the kneading mechanism 7 can drive the needle body 78 to move together to assist the needle insertion action.

After the treatment is completed, the user can rotate the screw 75 and use the threaded hole three 719 to drive the two splints 76 to move away from each other. When the splint 76 is separated from the needle body 78, the rotation of the screw 75 is stopped. Then the user can pull the needle body 78 out of the socket 722 to replace the needle body 78, and then disassemble and assemble the treatment needle as a disposable item to avoid cross infection between patients, or remove the non-disposable needle body 78 for additional disinfection, and the related fixing structure of the needle body 78 can also be disinfected to ensure the sterility of the needle body 78.

[0055] The operating steps of the present invention are:

[0056] When using the device to assist doctors in performing electroacupuncture, the user can place the mounting frame 1 on the treatment bed surface, and then the user can rotate the screw rod 4 according to the height of the needle insertion site of the patient's body shape. When the screw rod 4 rotates, the lifting plate 3, the adjustment mechanism 5, the needle feeding mechanism 6 and the kneading mechanism 7 are driven to move up and down through the threaded hole 48 to adjust the height of the needle body 78, so that the needle body 78 corresponds to the height of the patient's needle insertion site, and the doctor can use the adjustment mechanism 5 to adjust the angle of the needle body 78 according to actual treatment needs. At this time, the user can rotate the worm 55 and use the worm gear 54 to drive the rotating shaft 53 and the fixed frame 51, the needle feeding mechanism 6, and the kneading mechanism 7 to swing back and forth to adjust the vertical angle of the needle body 78. In this process, the needle can be adjusted by the indicator plate 510 and the angle ruler 10 The rotation angle of the needle body 78 can be judged. At the same time, the user can rotate the limit screw 515 to make the limit screw 515 disengage from the slide bar 1 58, and then pull the fixed plate 4 61 to rotate along the rotation axis 2 511 to adjust the horizontal angle of the needle body 78. When the fixed plate 4 61 rotates, the translation block 59 is driven to slide along the slide bar 1 58 through the fixed plate 3 519, the pull rod 518 and the sleeve frame 517, and the pull rod 518 slides in the sleeve frame 517. In this process, the swing angle of the needle body 78 can be judged by the indicator plate 2 516 and the scale plate 1 57. When the needle body 78 is adjusted to a suitable angle, stop pulling the fixed plate 4 61 to rotate, and rotate the limit screw 515 in the opposite direction to make the limit screw 515 contact with the slide bar 1 58 again to limit the position of the translation block 59 and the fixed plate 4 61.

[0057] The needle body 78 is adjusted to a suitable angle by using the adjustment mechanism 5, and then the limit rod 65 is pulled upward to make the limit rod 65 disengage from the limit hole 1 64 and the limit hole 2 618, and the fixing frame 2 67 is pulled leftward to make the fixing plate 6 11 slide leftward along the slide bar 2 66 to squeeze the spring 63. When the indicator plate 3 614 corresponds to the starting scale line of the scale plate 2 615, the pulling of the fixing frame 2 67 is stopped. At this time, the pushing device makes the tip of the needle body 78 contact the needle insertion site of the patient, and then the fixing frame 2 67 is released. The elastic force of the spring 63 is used to push the fixing frame 2 67, the kneading mechanism 7 and the needle body 78 to move right quickly, so that the tip of the needle body 78 quickly penetrates the patient's skin. When the right fixing plate 6 611 moves rightward to contact the right fixing plate 5 62, the needle body 78 penetrates the patient's body. At this time, the limit hole 1 64 corresponds to the limit hole 2 618, and then the user reinserts the limit rod 65 into the limit hole 1 64 and the limit hole 2 618;

[0058] Then the user can control the operation of the motor 1 616 and the motor 2 715 through the controller 2. When the motor 1 616 is working, it drives the screw 2 69 to rotate. When the screw 2 69 rotates, it drives the connecting plate 619, the kneading mechanism 7 and the needle body 78 to move rightward and continue to penetrate into the patient's body through the threaded hole 2 613. In this process, the speed of the needle body 78 can be controlled by adjusting the rotation speed of the motor 1 616. When the motor 2 715 is working, it drives the turntable 710 to rotate, and drives the tooth plate 717 to move back and forth by the fixed rod 711 and the connecting frame 79. When the tooth plate 717 moves back and forth, the gear 72 drives the mounting shaft 77 to rotate back and forth in a small range. The rotation of the mounting shaft 77 is used to simulate the twisting technique of the awn needle puncture method. While the needle is inserted, the kneading mechanism 7 is used to twist the needle body 78. During the insertion process, the numerical values ​​corresponding to the indicator plate 3 614 and the scale plate 2 615 can be observed to judge the insertion depth of the needle. When the insertion depth is reached, the motor 1 616 and the motor 2 715 are stopped.

[0059] After completing the treatment, the user controls the output shaft of motor 1 616 through controller 2 to reverse the direction so that the needle body 78 moves to the left and pulls the needle body 78 out of the patient's body. Then the user can rotate the lead screw 75 to use the threaded hole 3 719 to drive the two splints 76 away from each other. When the splint 76 is separated from the needle body 78, the rotation of the lead screw 75 is stopped. Then the user can pull the needle body 78 out of the socket 722 to replace the needle body 78.
