[0003] Data show that the global prevalence of chronic pain is about 38%, with a prevalence of 37% in developed countries and 41% in developing countries. The prevalence of chronic pain in women is higher than that in men, and the head, shoulders and waist are the main sites of chronic pain. In my country, there are more than 300 million chronic pain patients, and the number is increasing at a rate of 20 million per year. The prevalence of osteoarthritis increased by 2.35 times from 1990 to 2017; there were about 67.3 million patients with low back pain in 2016; there were about 483 million patients with headaches in 2017; and 16% of hospitalized patients had neuropathic pain.

[0004] According to a survey of muscle pain in six major cities in China, the incidence of muscle pain in the elderly is 65%-85%, and the rate of seeking medical treatment is 85%. The incidence of chronic pain in adults is 40%, and the rate of seeking medical treatment is 40%. In recent years, the population of pain patients has gradually become younger, and the main sources of disease are concentrated in cervical spondylosis, lumbar spondylosis, frozen shoulder, trigeminal neuralgia, etc. According to the survey results of Southwest Hospital, among more than 1,000 pain patients, 98% have experienced unbearable pain, and 84% have experienced insomnia, among which young white-collar workers account for a quarter.

[0005] The inventors of the present application discovered that when soft tissues such as muscles and tendons suffer local closed injuries, adhesions and other phenomena will occur in the surrounding soft tissues; since the human skin and other tissues have abundant and sensitive receptors (including pain receptors and other receptors), the receptors at the lesion site will experience symptoms such as pain due to stimulation.

[0006] Since the above-mentioned lesions will show different degrees of clinical manifestations in the human body after formation, in order to safely, quickly, efficiently and even completely eliminate the lesions, higher and more specific requirements are placed on the technical means of treatment and the safety, accuracy, strength and other functions that the treatment equipment needs to achieve.

[0007] So far, the traditional surgery, minimally invasive surgery, shock wave, acupuncture, massage, cupping, radiofrequency ablation and other technical means and equipment used in attempts to relieve the above-mentioned lesions have not been able to fully achieve the corresponding safety, accuracy and efficiency, and can only achieve temporary relief or treatment with potential safety risks.

[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0038] The disclosed embodiment provides a treatment pen for a limb pain treatment device, so as to achieve the purpose of treating the lesion site by using the treatment pen, thereby improving the pain or even eliminating the lesion.

[0039] In the embodiment of the present disclosure, the "proximal end" may be understood as the end of the treatment pen or a component of the treatment pen that is closer to the medical staff, and the "distal end" may be understood as the end of the treatment pen or a component of the treatment pen that is farther away from the medical staff.

[0040] The embodiment of the present disclosure provides a therapeutic pen for a limb pain therapeutic device, which, in addition to the therapeutic pen, also includes a host for outputting a vibration prescription signal to the therapeutic pen.

[0041] like Figure 1As shown, the treatment pen 1 comprises: a pen body 11 and a pen cap 12 detachably connected to the distal end of the pen body 11, the pen body 11 can be installed with a treatment needle 13 after the pen cap 12 is removed, and a switch button 14 is arranged on the surface of the pen body 11, a needle tube 131 of the treatment needle 13 extends out of the distal end of the pen cap 12, and a vibrator 15 that can be controlled to start and stop by the switch button 14 is arranged inside the pen body 11, and the vibrator 15 is used to transfer physical kinetic energy corresponding to the vibration prescription signal to the treatment needle 13 when it is turned on;

[0042] Among them, at least one of the treatment needle 13, the pen cap 12 and the pen body 11 has terahertz energy, and the frequency of the terahertz energy is 0.1THz-10THz.

[0043] like Figure 3 and Figure 4 As shown, the host 2 includes: a chassis 21, a touch screen 23 arranged on the surface of the chassis 21, and a CPU (Central Processing Unit) main control board 24 arranged in the chassis 21 and electrically connected to the touch screen 23. The CPU main control board 24 is used to output a vibration prescription signal to the vibrator 15 through the treatment pen output interface 22, and the touch screen 23 is used for the user to select the vibration prescription. The limb pain therapeutic instrument also includes at least one group of electrode sheets 3 electrically connected to at least one intermediate frequency output interface 26 through a cable. The CPU main control board 24 is also electrically connected to at least one intermediate frequency output interface 26 for outputting a current prescription signal to at least one group of electrode sheets 3. The current prescription signal can be an intermediate frequency current, and one group of electrode sheets 3 can include two electrode sheets 3. As shown Figure 6 As shown, the shock pulse frequency provided by the electrode sheet 3 is between 0.5KHz-3KHz, the pulse width is between 100μs-400μs, and the error is ±30%.

[0044] The therapeutic pen 1 provided in the embodiment of the present disclosure, the vibrator 15 can generate physical kinetic energy corresponding to the vibration prescription signal when it is turned on and receives the vibration prescription signal, and transmit the physical kinetic energy to the therapeutic needle 13 installed at the front end of the pen shaft 11. When the therapeutic needle 13 is used to treat the intervention lesion site, the physical kinetic energy is introduced into the lesion site with the needle, so that the lesions such as the adhesion nodules after the damage are better loosened, so as to achieve the treatment of the lesion site, thereby achieving the purpose of improving the pain or even eliminating the lesion. At the same time, since at least one of the therapeutic needle 13, the pen cap 12 or the pen shaft 11 of the therapeutic pen 1 has terahertz energy, it can radiate terahertz energy with a frequency of 0.1THz-10THz. The terahertz energy can penetrate the normal tissue of the human body and directly reach the lesion site, which can accelerate the repair of the lesion site, thereby improving the efficacy.

[0045] At least one of the treatment needle 13, the pen cap 12 and the pen body 11 has terahertz energy. Specifically, any one of the treatment needle 13, the pen cap 12 and the pen body 11 may have terahertz energy, or any two of the treatment needle 13, the pen cap 12 and the pen body 11 may have terahertz energy, or the treatment needle 13, the pen cap 12 and the pen body 11 may have terahertz energy at the same time. Preferably, the treatment needle 13, the pen cap 12 and the pen body 11 may have terahertz energy at the same time. In this way, terahertz energy can be continuously and stably radiated during the treatment process, and more terahertz energy is radiated, thereby improving the treatment efficiency.

[0046] In the treatment pen 1 provided by the present disclosure, when the treatment needle 13, the pen cap 12 or the pen body 11 has terahertz energy, the material of the treatment needle 13, the pen cap 12 or the pen body 11 should be a material that can store terahertz energy and meet medical standards. For example, it can be a medical metal material, preferably medical stainless steel.

[0047] In the treatment pen 1 provided in the present disclosure, the treatment needle 13 is a special treatment needle or a disposable syringe needle, which is used to intervene in the lesion site formed by soft tissue damage for diagnosis and / or treatment.

[0048] When the limb pain treatment device of the disclosed embodiment is in use, the user (referring to a practicing physician of a related profession) holds the treatment pen 1 and inserts the needle tube 131 of the treatment needle 13 into the lesion site. After the treatment needle 13 generates physical kinetic energy, the lesion site can be treated. The pen body 11 and the pen cap 12 of the treatment pen 1 are detachably connected. When the treatment pen 1 is idle, the treatment needle 13 is usually not installed to avoid stabbing the practicing physician of the related profession or contaminating the treatment needle 13. When the lesion needs to be treated, the pen cap 12 can be removed from the pen body 11, and the treatment needle 13 can be installed on the mounting bracket 17 of the pen body 11. Then, the pen cap 12 is fixed to the pen body 11. At this time, the needle tube 131 extends out of the needle tube outlet hole 122 opened at the far end of the pen cap 12 and thus extends out of the pen cap 12. The treatment needle 13 can be a special treatment needle or a universal disposable syringe needle, which is used to intervene in the lesion site formed by soft tissue damage for diagnosis and / or treatment. The advantages of this treatment needle are tough texture, high precision, simple installation, and convenient replacement. After intervention in the lesion, the skin wound is small, the pain caused to the patient is small, and the recovery is also rapid.

[0049] A switch button 14 is provided on the surface of the pen shaft 11, and the switch button 14 can be a push-type or sliding structure. The switch button 14 can control the start and stop of the vibrator 15, so the switch button 14 can be directly or indirectly electrically connected to the vibrator 15, and when the vibrator 15 is turned on, physical kinetic energy can be generated. The vibrator 15 is in direct or indirect contact with the treatment needle 13, or the vibrator 15 and the treatment needle 13 are directly or indirectly fixedly connected, so that the vibrator 15 can transfer physical kinetic energy to the treatment needle 13. When the treatment needle 13 is inserted into the lesion site, the physical kinetic energy can be brought into the lesion site, so that the lesions such as adhesion nodules can be better loosened, thereby achieving the treatment of the lesion site, so as to achieve the purpose of improving the pain or even eliminating the lesion.

[0050] When the limb pain treatment device of the embodiment of the present disclosure is used to treat the lesion site of the human body, the practitioner of the relevant profession operates the physical entity switch set on the host 2, the host 2 is started, and the touch screen 23 is turned on. After the practitioner of the relevant profession operates the touch screen 23 to log in or set up, the vibration prescription can be selected, and the CPU main control board 24 can output the vibration prescription signal corresponding to the vibration prescription, and transmit the vibration prescription signal to the vibrator 15 of the treatment pen 1 through the treatment pen output interface 22. Then, the practitioner of the relevant profession installs the treatment needle 13 on the mounting bracket 17 of the pen body 11, and after the pen cap 12 is fixed on the pen body 11, press the timing "run" key on the touch screen 23 to insert the treatment needle 13 into the lesion site, and then operate the switch button 14, the vibrator 15 can be started, and physical kinetic energy is generated according to the vibration prescription signal, and the physical kinetic energy is transmitted to the treatment needle 13, so that the treatment needle 13 brings the physical kinetic energy into the lesion site for treatment. When the treatment of the lesion site is completed, the switch button 14 can be stopped, the vibrator 15 stops vibrating, and then the treatment needle 13 is pulled out of the lesion site, and the vibration prescription is selected on the touch screen 23 again, and the above operations are continued until the treatment of all lesions of the patient is completed.

[0051] It should be noted that when using the limb pain treatment device of the embodiment of the present disclosure to treat the lesion site of the human body, a practicing physician of a related profession may first install the treatment needle 13 on the mounting bracket 17 of the pen shaft 11, and then operate the physical entity switch provided on the host 2 to start the host 2. The CPU main control board 24 may output the vibration prescription signal corresponding to the vibration prescription to the vibrator 15 of the treatment pen 1 through the treatment pen output interface 22. The vibrator 15 can generate physical kinetic energy corresponding to the vibration prescription signal after being turned on and when receiving the vibration prescription signal, and transmit the physical kinetic energy to the treatment needle 13 installed on the pen shaft 11, so that the treatment needle 13 will bring in physical kinetic energy while intervening in the lesion site, so that the nodules / adhesions generated after the damage can be better loosened, so as to achieve the treatment of the lesion site, thereby achieving the purpose of improving the pain or even eliminating the lesion.

[0052] In some embodiments, Figure 2a As shown, the distal end of the pen barrel 11 is provided with an elastic bead 16 for installing and releasing the pen cap 12, wherein the number of the elastic bead 16 can be at least one. Specifically, the outer surface of the elastic bead 16 is provided with an external thread, and a threaded hole is provided at the distal end of the pen barrel 11. The elastic bead 16 is fixed in the threaded hole of the pen barrel 11 through the external thread. Since the bead on the elastic bead 16 can compress the spring when subjected to pressure, when the pen cap 12 is installed on the pen barrel 11 through the elastic bead 16, the spring in the elastic bead 16 is in a compressed state, that is, a pressure is provided for the pen cap 12, so that friction is generated between the pen cap 12 and the elastic bead 16, thereby fixing the pen cap 12 and the pen barrel 11. When the pen cap 12 needs to be removed, the elastic bead 16 can be released by applying a force greater than the friction force on the pen cap 12, thereby removing the pen cap 12 from the pen barrel 11. The above technical solution has a simple structure and is easy to operate.

[0053] A contact surface 121 is provided inside the pen cap 12, and the contact surface 121 is located at the distal end of the pen cap 12. The treatment needle 13 also includes a needle tube seat 132 fixedly connected to the needle tube 131. When the treatment needle 13 is fixed on the pen shaft 11, the distal end surface of the needle tube seat 132 contacts the contact surface 121. In this way, the contact surface 121 inside the pen cap 12 can limit the movement of the treatment needle 13 along the length direction of the pen shaft 11, thereby improving the installation stability of the treatment needle 13, reducing the movement of the treatment needle 13 during physical vibration, and further improving the safety of the treatment needle 13 when performing treatment at the interventional lesion site.

[0054] In addition, in order to further improve the safety of the treatment needle 13, a needle tube outlet hole 122 is provided at the distal end of the pen cap 12. When the treatment needle 13 and the pen cap 12 are fixed to the pen shaft 11, the needle tube 131 passes through the needle tube outlet hole 122 and extends out of the distal end of the pen cap 12, and the needle tube outlet hole 122 and the needle tube 131 are clearance-matched. In this way, the needle tube outlet hole 122 can limit the lateral displacement of the treatment needle 13, thereby further improving the safety of the treatment needle 13.

[0055] In some embodiments, Figure 5 As shown, the needle tube seat 132 includes a needle tube fixing part 1321 and a clamping part 1322 fixedly connected to the needle tube fixing part 1321, the needle tube fixing part 1321 is penetrated with a needle tube mounting hole 1323, the needle tube 131 is inserted and fixed in the needle tube mounting hole 1323, the clamping part 1322 is annular and hollow, and the cavity of the clamping part 1322 is connected with the needle tube mounting hole 1323. Since the needle tube 131 is inserted and fixed in the needle tube mounting hole 1323, the cavity of the clamping part 1322 is connected with the needle tube mounting hole 1323, and therefore, the cavity of the clamping part 1322 is also connected with the needle tube 131. Here, the material of the needle tube 131 can be medical stainless steel, and the material of the needle tube fixing part can be medical plastic, specifically transparent medical plastic.

[0056] like Figure 2a and Figure 5 As shown, the treatment pen 1 further includes a mounting bracket 17 disposed inside the pen holder 11, the mounting bracket 17 includes a bracket body 171 extending along the length direction of the pen holder 11 and a mastoid 172 fixedly connected to the distal end of the bracket body 171, and the clamping portion 1322 is sleeved and fixed on the mastoid 172. The mounting bracket 17 and the pen holder 11 can be an integrally formed structure, or the mounting bracket 17 and the pen holder 11 can be fixedly connected.

[0057] The cross section of the pen barrel 11 is an annular cross section, so there is a cavity inside the pen barrel 11, and the mounting bracket 17 can be arranged in the cavity of the pen barrel 11. The mounting bracket 17 includes a bracket body 171 extending along the length direction of the pen barrel 11 and a mastoid 172 fixedly connected to the distal end of the bracket body 171, wherein the mounting bracket 17 can be completely located in the cavity in the pen barrel 11, that is, the bracket body 171 and the mastoid 172 are both located in the cavity in the pen barrel 11, and the distal end of the mastoid 172 does not exceed the distal end of the pen barrel 11; the mounting bracket 17 can be partially located in the cavity in the pen barrel 11, that is, the bracket body 171 is located in the cavity in the pen barrel 11, and the distal end of the bracket body 171 and the distal end of the pen barrel 11 are located in the same plane, and the mastoid 172 exceeds the distal end of the pen barrel 11.

[0058] Since the clamping portion 1322 of the needle tube seat 132 is annular and hollow, the cross section of the outer surface of the mastoid 172 that is fixedly connected to the clamping portion 1322 can also be a circular cross section, and the clamping portion 1322 and the mastoid 172 can be interference fit or transition fit. In this way, the treatment needle 13 can be more stably fixed on the pen holder 11, thereby further improving the safety of the treatment pen 1.

[0059] In some embodiments, Figure 2a and Figure 5 As shown, the bracket body 171 includes a first body portion 1711 and a second body portion 1712 which are arranged opposite to each other and fixedly connected, and the vibrator 15 is fixedly connected between the first body portion 1711 and the second body portion 1712. The cross-sections of the first body portion 1711 and the second body portion 1712 can both be semi-circular, and the bracket body 171 formed after the two are fixedly connected is annular and hollow, so that it can be better fixedly connected to the pen holder 11. In addition, the first body portion 1711 can be snapped into the second body portion 1712. When assembling the treatment pen 1, the vibrator 15 can be fixedly connected to the first body portion 1711, and then the first body portion 1711 and the second body portion 1712 are fixedly connected. Therefore, this structure not only makes the internal structure of the treatment pen more compact, but also facilitates assembly.

[0060] Since there is a hollow structure between the first body portion 1711 and the second body portion 1712, a base film can be set at the distal ends of the first body portion 1711 and the second body portion 1712, and the nipple 172 is fixedly connected to the first body portion 1711 and the second body portion 1712 through the base film, and the material of the base film is a transparent material.

[0061] In addition, a vibrator 15 can be fixedly connected between the first body portion 1711 and the second body portion 1712. After the vibrator 15 generates physical kinetic energy, the physical kinetic energy can be transferred to the first body portion 1711 and the second body portion 1712, and then transferred to the mastoid 172 and the treatment needle 13.

[0062] The mounting bracket 17 also includes a side wall 173 fixed to the distal end of the first body portion 1711 and the second body portion 1712 and surrounding the mastoid 172, and the side wall 173 is in contact with the outer side of the needle tube seat 132. That is, an annular groove 174 is formed between the mastoid 172 and the side wall 173, and after the needle tube seat 132 is fixed on the mastoid 172, the needle tube seat 132 is also located in the annular groove 174, and the side wall 173 is in contact with the outer side of the needle tube seat 132, so that the mastoid 172 and the side wall 173 can better fix and limit the displacement of the needle tube seat 132, so that the treatment needle 13 can be more stably fixed on the needle tube 131, thereby further improving the safety of the treatment pen 1.

[0063] In some embodiments, Figure 2a , Figure 2b and Figure 5 As shown, an ultraviolet disinfection band LED emitter 185 that emits light toward the treatment needle 13 is provided at the distal end of the pen shaft 11, and is used to perform ultraviolet disinfection on the mastoid 172 and the side wall 173. The ultraviolet disinfection band LED emitter 185 can be integrated on the PCB control board 18, and the light emission direction is toward the treatment needle 13 and is located at the distal end of the PCB control board 18. Since a mastoid 172 for fixing the treatment needle 13 is provided on the bracket body 171, a light-transmitting hole can be provided through the mastoid 172, so that the ultraviolet light emitted by the ultraviolet disinfection band LED lamp can irradiate the mastoid 172, the side wall 173 and the pen cap 12, thereby performing ultraviolet disinfection on the mastoid 172, the side wall 173 and the pen cap 12, and then keeping the mastoid 172 and the side wall 173 clean. Since a bottom film made of a transparent material is disposed at the distal ends of the first body portion 1711 and the second body portion 1712 , the bottom film can prevent the accumulated liquid from flowing to the ultraviolet disinfection band LED lamp.

[0064] In some embodiments, Figure 2a and Figure 5 As shown, the pen cap 12 is provided with at least one window 123 along the circumference, and the needle tube seat 132 is a needle tube seat 132 of a transparent material, and the needle tube seat 132 can be observed through each window 123. In order to achieve the purpose of being able to observe the needle tube seat 132 through each window 123, the setting position of the window 123 on the pen cap 12 corresponds to the needle tube seat 132. In the process of using the treatment pen 1 to treat the lesion site, after the treatment needle 13 is inserted into the lesion site, if there is fluid accumulation in the lesion site, the fluid accumulation flows to the needle tube seat 132 through the needle tube 131 under the action of the internal pressure of the lesion site, and the medical staff can observe whether there is fluid accumulation in the patient's lesion site through the window 123, which is convenient for determining further treatment plans. In addition, the window 123 is provided on the pen cap 12, which can play the role of safety protection, facilitating observation, stable installation, safety and hygiene, smooth installation, and convenient treatment. The material of the pen cap 12 includes alloy material.

[0065] In some embodiments, Figure 2a , Figure 2b and Figure 5As shown, a PCB (Printed Circuit Board) control board 18 is also provided inside the pen body 11. The PCB control board 18 is integrated with an LED backlight 181, a vibration indicator light 182 and a switch button 14. The LED backlight 181 and the switch button 14 are exposed on the surface of the pen body 11. A working observation hole is also provided on the surface of the pen body 11. The working observation hole corresponds to the position of the vibration indicator light 182, and the LED backlight 181 is closer to the far end of the pen body 11 than the vibration indicator light 182. The PCB control board 18 is also electrically connected to the vibrator 15, and specifically, the vibrator 15 and the PCB control board 18 are welded and fixed.

[0066] The LED backlight 181 integrated on the PCB control board 18 is closer to the distal end of the pen shaft 11 than the vibration indicator light 182. Thus, when medical staff use the treatment pen 1 to treat the lesion, the LED backlight 181 can also provide lighting for the medical staff, thereby enabling the medical staff to more clearly observe from the viewing window 123 whether there is fluid accumulation in the needle tube seat 132.

[0067] In addition, the vibration indicator light 182 is exposed on the surface of the pen body 11. This can be achieved by setting the pen body 11 and the bracket body 171 to transparent materials, or by setting mounting holes on the bracket body 171 and the pen body 11 so that the vibration indicator light 182 protrudes from the surface of the pen body 11.

[0068] The switch button 14 can be a push-type or toggle-type structure. Since medical personnel are required to press or toggle the switch button 14 , the switch button 14 needs to protrude from the surface of the pen barrel 11 .

[0069] The connection mode between the host 2 and the treatment pen 1 includes a wired connection and / or a wireless connection. When the host 2 is wirelessly connected to the treatment pen 1, a Bluetooth connection, an infrared connection or a Wi-Fi connection can be used. The host 2 also includes a first signal transceiver module (not shown in the figure) located in the chassis 21 and electrically connected to the CPU main control board 24. The CPU main control board 24 can output a vibration prescription signal to the treatment pen 1 through the first signal transceiver module; the treatment pen 1 also includes a second signal transceiver module for receiving the vibration prescription signal, and a first power supply device for supplying power to the vibrator 15, the second signal transceiver module and the switch button 14. The first power supply device may include: a button battery, a dry battery or a rechargeable battery.

[0070] In some embodiments, when the host 2 is connected to the therapeutic pen 1 by wire, the host 2 and the therapeutic pen 1 are electrically connected via a cable. Specifically, a therapeutic pen output interface 22 electrically connected to the CPU main control board 24 is also provided on the surface of the chassis 21. The therapeutic pen output interface 22 is electrically connected to the therapeutic pen 1 via a cable. The host 2 can supply power to the therapeutic pen 1 and transmit vibration prescription signals via the therapeutic pen output interface 22 and the cable.

[0071] In some embodiments, Figure 5 As shown, a cable hole 112 is provided at the proximal end of the pen shaft 11, and a wire card 113 is sleeved on the cable hole 112. The cable connected to the PCB control board 18 passes through the cable hole 112 and is fixed by the wire card 113, and is electrically connected to the vibration signal output interface 22 of the host 2, that is, one end of the cable is electrically connected to the host 2, and the other end of the cable passes through the cable hole 112 and is electrically connected to the PCB control board 18. The PCB control board 18 is used to receive the vibration prescription signal from the CPU main control board 24 and output it to the vibrator 15.

[0072] The line card 113 can also be provided with a cable fixing hole 114, and the cable connected to the PCB control board 18 can pass through the cable fixing hole 114 of the line card 113 and be connected to the vibration signal output interface 22 of the host 2. The material of the line card 113 can usually be plastic or rubber, which can protect the cable and reduce the damage to the cable caused by the friction between the cable and the cable hole 112 on the treatment pen 1. The vibration prescription signal of the CPU main control board 24 can output the vibration prescription signal to the PCB control board 18 through the cable, and then the PCB control board 18 controls the vibration frequency, amplitude and vibration speed of the physical vibration of the vibrator 15 according to the vibration prescription signal. Among them, the vibration frequency refers to the number of vibration cycles generated by the vibrator 15 per second; the amplitude represents the maximum vibration displacement of the vibrator 15; the vibration speed represents the effective value of the speed of the vibrator 15 during the vibration process, specifically representing the value obtained by the derivative of the vibration amplitude with respect to time; the duty cycle represents the proportion of the duration of vibration in a vibration cycle to the total duration in the vibration cycle.

[0073] In other embodiments, a vibration signal input interface is provided at the proximal end of the pen body 11, and the vibration signal input interface is electrically connected to the vibration signal output interface 22 of the host 2 through a detachable cable; the PCB control board 18 is also electrically connected to the vibrator 15 and the vibration signal input interface respectively, and the PCB control board 18 is used to receive the vibration prescription signal from the CPU main control board 24 and output it to the vibrator 15. When the treatment pen 1 is needed to treat the lesion, a cable can be used to connect the vibration signal input interface of the treatment pen 1 and the vibration signal output interface 22 of the host 2. When the host 2 is not needed, the cable can be unplugged and stored.

[0074] In some embodiments, the trajectory of the vibration output by the vibrator 15 is in a plane perpendicular or parallel to the axis of the pen holder 11, and the vibration trajectory includes: a trajectory of reciprocating motion in a single direction, and / or a trajectory of centrifugal reciprocating motion in multiple angular directions with the axis of the pen holder 11 as the center. The single direction and the multiple angular directions are both in a plane perpendicular to the axis of the pen holder 11, and the single direction can be any direction in the plane perpendicular to the axis of the pen holder 11, and the vibrator 15 can obtain vibration trajectories with different single directions by changing the installation direction of the vibrator 15 in the pen holder 11.

[0075] The trajectory of the centrifugal reciprocating motion along multiple angular directions may specifically be: reciprocating motion cyclically along multiple angular directions in a clockwise or counterclockwise direction. Figure 6 This is a schematic diagram of the vibration trajectory of the vibrator in some embodiments of the present invention. For multiple angular directions, reciprocating motion can be performed along a first angular direction d first, and then reciprocating motion can be performed clockwise along a second angular direction e. After the reciprocating motions in multiple angular directions are completed, reciprocating motion can be performed along the first angular direction d again, and so on.

[0076] In addition, the center of gravity of the vibrator 15 and the center of gravity of the treatment pen 1 can coincide with the axis of the pen shaft 11, which can reduce the eccentric load caused by centrifugal vibration, resulting in excessive amplitude of the vibrator 15 and causing damage to the lesion site.

[0077] In some embodiments, the vibrator 15 is an electromagnetic mechanical vibrator 15, the amplitude of the vibrator 15 is designed to be between 2 μm and 500 μm, and the vibration frequency of the vibrator 15 is designed to be between 5 Hz and 500 Hz. The amplitude of the vibrator 15 is limited within the aforementioned range to avoid additional damage to the lesion site due to excessive vibration amplitude in the lesion site.

[0078] In addition, the physical kinetic energy generated by the vibration prescription is brought into the lesion site through the treatment needle 13, so that the blood and body fluid circulation and metabolic functions of the lesion site are improved; and because the diameter of red blood cells is about seven microns, the amplitude of the physical kinetic energy brought in by the treatment needle 13 is larger than the diameter of red blood cells. Therefore, during the treatment process, the metabolism and exchange of harmful substances carried by red blood cells in the metabolism of oxygen between tissues can be unobstructed, and tiny particles of harmful substances can be metabolized away from the painful lesion site, thereby accelerating the healing of the lesion site and achieving the purpose of treatment.

[0079] In order to facilitate the medical staff to hold the treatment pen 1, the outer diameter of the pen body 11 of the treatment pen 1 is between 5mm-50mm, the distance between the distal end of the pen cap 12 and the proximal end of the pen body 11 is between 30mm-300mm, the distance between the distal end of the pen cap 12 and the vibration signal input interface is between 30mm350mm, the distance between the distal end of the treatment needle 13 and the proximal end of the pen body 11 is between 45mm-400mm, and the distance between the center of the switch button 14 and the distal end of the pen cap 12 is between 10mm-100mm. In this way, it is more convenient for medical staff to hold and operate, and reduce operational errors caused by large finger movements when pressing the switch button 14.

[0080] The limb pain treatment device of the embodiment of the present disclosure can be used to treat the lesion site according to the following steps:

[0081] 1) Before treatment, ensure that the surface of the affected area is clean and placed stably, that all accessories of the limb pain treatment device are firmly connected, that the power supply has a ground wire, and that the host 2 is in a stopped or turned off state or the intensity is zero.

[0083] 3) Preparation of electrode sheet 3.

[0084] 4) The electrode sheet 3 is electrically connected to the host 2, and the electrode sheet 3 is attached to the lesion site. The better the effect is, the better the contact with the skin.

[0089] ④ First install the sterile treatment needle 13 on the mounting bracket 17 of the pen body 11, then gently install and fasten the sterilized pen cap 12 of the treatment pen 1, and lightly press the switch button 14, appropriately adjust the individual vibration intensity level or select the lesion site, test the vibration function of the treatment pen 1 to see if it is normal, and then it is ready for use.

[0090] Press the timing "Run" button on the touch display screen 23, insert the treatment needle 13 into the lesion site, and then continue to press the switch button 14 of the pen body 11 to loosen and restore the lesion with the help of physical kinetic energy.
