[0009] Through the technical scheme, the heating module is used for synchronously heating the plurality of needle rollers on the surface of the cylinder body of the micro-needle roller when starting to work. During the acupuncture process, the medical staff holds the connecting handle and rotates the micro-needle roller relative to the connecting handle, sequentially inserts the needle rollers into the skin lesion part, so that the heated needle rollers realize the heat stimulation on the surface of the skin, stimulate the human meridian qi through the organic combination of acupuncture and heat transfer, and achieve the effect of treating human diseases. Meanwhile, the detachable protective cap is arranged to avoid the situation that the needle rollers on the portable electric heating needle roller hurt others when not in use.

[0010] Preferably, the micro-needle roller comprises:

[0011] The rotating drum is a hollow cylindrical drum with two open ends, and heat insulation limiting rings are fixedly installed on the outer side walls of the two ends of the rotating drum.

The resilient rubber ring in the positioning hole is elastically deformed due to extrusion, so that the resilient pin is positioned in the positioning hole and is not easy to fall off. When it is necessary to disassemble and replace, the resilient pin can be pulled out with force, so that the handle side clamping strip can be quickly disassembled and replaced.

[0027] Preferably, the handle body is internally provided with a cavity, the power module is installed in the cavity, and the display and the control assembly are installed on the handle body.

The heat insulation limiting ring 140 is used to limit the position and prevent the microneedle annular sheet 120 and the movable heat insulation ring 130 from falling off the rotating drum 110. The movable heat insulation ring 130 is used to block the direct contact of the patient's skin surface with the outer side wall of the rotating drum 110, so as to reduce the accidental scalding of the patient's skin by the outer side wall of the rotating drum 110.

[0055] The heating module 200 is fixedly installed in the rotating drum 110 of the microneedle roller 100 for electric heating. Specifically, the heating module 200 comprises a heat conduction drum 210, a display 220, a control assembly and a power module 240.

The power module 240 is electrically connected with the electric heating rod 270, the temperature sensor 280 and the control assembly respectively, and is used for supplying power to the electric heating rod 270, the temperature sensor 280 and the control assembly respectively. It should be noted that the control assembly described herein is the power-on switch of the conventional circuit, which is the most basic and conventional technical means in the circuit field, and therefore its specific structure and working principle will not be described in detail herein. In this example, the power module 240 is realized by using a rechargeable battery. In addition, a power external interface corresponding to the power module 240 can be further provided on the device to fully ensure the long-term stable operation of the device. In addition, the connecting handle 300 can also be configured to include an ergonomic holding structure to make it more convenient and labor-saving to hold when in use. The microneedle roller 100 is movably installed on the connecting handle 300, and the microneedle roller 100 is further configured to be rotatable relative to the connecting handle 300. Specifically, the connecting handle 300 includes a handle body 310 and a side clamping strip 320, the first blocking piece 250 is rotationally connected to the handle body 310, the side clamping strip 320 is detachably fixedly connected with the handle body 310 as a whole, and the side clamping strip 320 is configured to be rotationally connected with the second blocking piece 260 when the side clamping strip 320 is fixedly connected with the handle body 310 as a whole. In practice, the side clamping strip 320 can be selectively positioned by a structure of a positioning screw 313 / elastic pin 315 to realize detachable connection of the handle body 310. Specifically, the first scheme is that the handle body 310 is provided with a slot 311, and the side clamping strip 320 is provided with a plug strip 322 matched with the slot 311; the handle body 310 is further provided with a threaded hole 312 vertically and conductively leading to the slot 311, and the threaded hole 312 is detachably installed with a positioning screw 313.In the process of assembling the handle body 310 and the side clamping strip 320, the insertion strip 322 is inserted into the insertion slot 311, and the positioning screw 313 is screwed into the threaded hole 312, so that the end of the positioning screw 313 is deep into the insertion slot 311 and is screwed into the fixing hole 321 on the insertion strip 322, that is, the detachable fixing of the side clamping strip 320 to the handle body 310 is achieved. The second solution is that the handle body 310 is provided with an insertion slot 311, and the side clamping strip 320 is provided with an insertion strip 322 matched with the insertion slot 311; the handle body 310 is also provided with a positioning hole 314 vertically connected to the insertion slot 311, and a resilient pin 315 is detachably installed on the positioning hole 314, and the cylindrical surface of the resilient pin 315 is provided with a resilient rubber ring 316 matched with the hole diameter of the positioning hole 314 (slightly larger than the hole diameter of the positioning hole 314, but due to its elastic material, it can be squeezed into the positioning hole 314 after being forced).

The resilient rubber ring 316 is elastically deformed in the positioning hole 314, and the resilient pin 315 is positioned in the positioning hole 314, so that it is not easy to fall off. When it is necessary to disassemble and replace, the resilient pin 315 can be pulled out with force to disassemble the handle side clamping strip 320 for quick replacement.

[0057] The inside of the handle body 310 is provided with a cavity, and the power supply module 240 and the control circuit board 290 in the control assembly are installed in the cavity. The display 220 and the control assembly are exposed and installed on the surface of the handle body 310.

[0058] The protective cap 400 is detachably installed on the outside of the barrel of the microneedle roller 100. In this example, the electric heating rod is made of one of PTC heating body, heating resistance wire, heating graphene, and heating carbon fiber. The heat-conducting barrel 210 is made of one of aluminum, copper, iron, high-thermal-conductivity ceramic, high-thermal-conductivity nanometer material, and heat-conducting plastic.

[0059] In practice, the working process is as follows:

[0060] When the device is in a state ready for use, the connecting handle 300 is detached from the microneedle roller 100 (to meet the above-mentioned disassembly needs, each power supply wire and signal wire involved in the present solution should be provided with a corresponding connecting port for disconnection / continuation, which is a common technical means in the art and will not be described here) and enters a state of use. After entering the state of use, the fixed side edge clamping strip 320 is used to achieve the rotational connection of the connecting handle 300 and the microneedle roller 100. The heating module 200 is used to synchronously heat the plurality of needles on the surface of the cylinder of the microneedle roller 100 when starting to work. During the needle insertion process, the medical staff holds the connecting handle 300 and rotates the microneedle roller 100 relative to the connecting handle 300 to sequentially insert the needles into the lesion site, thereby greatly reducing the treatment time. After the electric heating rod 270 is powered on, the heat generated by the electric heating rod 270 is conducted to the rotating cylinder 110 through the heat-conducting cylinder 210. In this process, the temperature sensor 280 obtains the temperature value of the heat-conducting cylinder 210 and displays it through the display 220. The medical staff controls the control assembly according to the reading of the display 220 to control the power-on state of the electric heating rod 270, thereby avoiding the problem of accidental burns and equipment damage caused by excessively high heating temperature.
