Description

Skin roller pin with adjustable depth

Technical Field

The invention relates to the technical field of medical instruments, in particular to a depth-adjustable skin needle roller.

Background

The medical and cosmetic industries are all dedicated to how to accurately and efficiently transport the medicine to the application site, and with the development of technology, a method of micro-needle plastic making is commonly used, wherein a roller micro-needle is adopted to pierce the skin, thousands of micro-conveying pipelines can be manufactured on the skin surface by the micro-needle in a short time, so that the cosmetic nutrient components or the medicine components directly penetrate into the deep layer of the skin from the point, and the absorption effect of the product is 4000 times or more than that of a common smearing product.

In the prior art, although the common skin rolling needle can smoothly pierce the epidermis skin, the pressure stability of the rolling needle in the process of rolling back and forth on the skin surface cannot be ensured, especially when the rolling needle is used, the rolling needle needs to roll in the longitudinal, transverse and 45-degree directions on the skin surface, and the speed is difficult to control uniformly in the rolling process, so that the pressure born by the rolling needle is unstable, the penetration depth of the rolling needle into the skin is inconsistent, the permeability of a medicine or cosmetic product is inconsistent, even the dermis layer of the skin is pierced, and subcutaneous tissues are damaged.

Thus, as proposed in the publication CN208260010U, the length of the needle is controlled by the telescopic slide plate, and the depth of penetration into the skin can be controlled by providing a cleaning sponge, and the needle is always clean. The mode of the device controlling the penetration depth of the needle roller is not to stretch or improve the needle roller, but the penetration depth is limited by limiting, so that the needle roller can be effectively prevented from penetrating too deeply into the skin, but the needle roller is not easy to penetrate enough into special parts of the skin such as the nose side, in addition, in the rolling process of the needle roller, the contact angle between the needle roller handle and the skin needs to be adjusted timely due to factors such as the habit of a doctor, the lying posture of a patient, the neck heightening degree, the face shape of the patient and the like, the needle roller is arranged on the roller in a rotating way, the adjustment is not needed, and the sliding plate limiting the needle roller also needs to be arranged in a rotating way.

And compare in the microneedle of a little skin of vertical puncture of single, the advantage of kingpin just lies in can puncture manufacturing pipeline through the roll puncture high efficiency, but compare in the perpendicular puncture of microneedle, the roll puncture of kingpin, can form the contained angle with skin when the kingpin contacts skin and leaves skin, the puncture of kingpin with pull out non-perpendicular puncture and pull out, consequently lead to the fact the puncture mouth to become the toper, the puncture mouth also causes the puncture mouth bigger than the microneedle, the skin damage degree is higher, and the contained angle that forms with skin is determined by the radius of rotation of kingpin, the greater then the contained angle is less of radius of rotation, and the use scene has decided that the radius of rotation of kingpin is unlikely to set up too big, consequently conventional roll causes the toper damage to skin inevitably.
