Description

Technical Field

[0001] The utility model relates to the technical field of micro-needle treatment, and in particular to a negative pressure gold micro-needle treatment device. Background Art

[0002] Gold microneedle therapy device is a common beauty device used to destroy fat layer cells. Gold microneedle uses radio waves emitted by radio frequency therapy device into subcutaneous tissue, causing fat particles in subcutaneous tissue to move and generate heat energy. It uses the principle that collagen fibers in the dermis will immediately contract at 55℃-65℃ and the principle of radio wave skin tightening, and has two functions of lifting the skin and promoting collagen regeneration. While collagen produces immediate contraction, it also stimulates the dermis to secrete more new collagen fibers for regeneration, thereby supporting the skin's scaffold again, increasing the thickness and density of the dermis, filling wrinkles, and improving sagging.

[0003] During the treatment process, the gold microneedle needs to accurately reach a certain subcutaneous depth to produce a better treatment effect. However, due to the complexity of the human epidermis, the gold microneedle needs to be lifted by the operator to achieve this effect, resulting in different effects for operators with different proficiency. Therefore, the market has begun to use negative pressure to lift and flatten the skin to achieve a better treatment effect, thereby reducing the technical requirements for operators and facilitating the promotion of treatment effects and products.

[0004] During the radio frequency microneedle treatment process, the needle body needs to be inserted into the skin. The treated subject will feel pain when the needle body enters the skin, and the intensity of the pain is related to the speed of needle removal. The faster the needle removal speed, the milder the pain, and the slower the needle removal speed, the stronger the pain.

[0005] In specific applications, most radio frequency microneedle treatment devices on the market use a lead screw stepper motor or a screw motor to directly drive the microneedle assembly to remove the needle, but the needle removal speed is slow, causing the treated person to suffer greater pain during treatment.

[0006] In addition, most of the negative pressure gold microneedle therapy devices on the market generate negative pressure by connecting the air tube outside the microneedle treatment head to the treatment handle body after the filter element is connected to form a pressurized air path. This method will cause the microneedle treatment head to drag the suction channel and filter when in use, affecting the operator's gestures and vision; in addition, the filter and the needle are installed separately, which is cumbersome to operate and easily leads to poor sealing, while affecting the aesthetics of the product.
