Description

Improved roller microneedle

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to an improvement gyro wheel micropin.

Background

The micro needle therapy for treating chloasma, acne scar and the like on the face is a more popular technique in plastic cosmetology at present, and mainly adopts a micro needle roller, and uses a micro needle instrument to implement skin soft tissue administration and physical stimulation, so that required medicinal components are introduced into the skin, and the skin soft tissue is stimulated to start a damage repair mechanism and tissue regeneration, thereby achieving the effect of treatment or cosmetology. The micro-needle has the advantages that mesoderm drugs required by the skin can penetrate through the stratum corneum and enter the epidermis or even the dermis, and compared with the traditional subcutaneous injection, the micro-needle is almost free of wound, free of obvious pain and high in bioavailability. Factors affecting transdermal efficiency of the microneedles are mainly skin conditions of patients, physical properties of the microneedles, properties of mesodermal drugs, and the like. The physical factors of the micro-needle account for the effect which is not negligible, the skin stratum corneum channel is opened in a mode of destroying and changing the skin barrier in a short time through the stimulation of the micro-needle body, and the percutaneous absorption amount of the medicine is increased through the micro-pore channel formed on the surface of the skin.

At present, the micro-needle which is commonly used in clinic in plastic and cosmetic surgery is a disposable sterile skin rolling needle, the number of the rolling wheel sheets is 3-9, the diameter of the rolling wheel is 20mm, the diameter of the needle body is 0.25mm, and the length of the needle body is 0.5 mm-3.0 mm. The microneedles with different types have different needle point lengths and different needling depths. The acupuncture degree of depth of micropin can influence transdermal rate at to a great extent, different diseases are different to the requirement of micropin needle body length, it is 0.5mm to use needle body length more clinically, 1mm carries out the percutaneous absorption of facial medicine, but especially exceed the hypertrophic scar of leather side to the scar, because scar density is great and unsmooth, acupuncture degree of depth then can't the inside tow of better separation scar not enough, the different micropins of needle body length need be changed according to particular case this moment and the cooperation is used.

At present, the most that clinically uses is disposable aseptic micropin, micropin needle body length is fixed, need change the micropin of different models or change different models micropin syringe needle in order to reach the target depth according to concrete clinical situation during the use, so not only increase apparatus consumptive material quantity, cause the increase of patient treatment expense, also can lead to the wasting of resources simultaneously.

Chinese patent documents: CN201220604693.1, application date 2012.11.15, patent names: a roller microneedle device. Disclosed is a roller microneedle device, comprising: the roller micro needle body is formed by connecting a plurality of roller micro needles; two connecting sheets arranged at two sides of the roller micro-needle body; and the handle part is rotationally connected with the two connecting sheets.

Chinese patent documents: CN201310045494.0, application date 2013.02.05, patent names: layered replaceable roller microneedle tools. Discloses a layered microneedle tool with replaceable rollers, and relates to a drug controlled release and skin minimally invasive device. It includes: the outer surface is circumferentially provided with a ring-shaped sheet of the micro-needle, the ring-shaped sheet is in contact connection to form a sheet-shaped layered micro-needle roller, two sides of the formed micro-needle roller are connected with connecting sheets, the ring-shaped sheet and the connecting sheets are clamped in a handle, and the sheet-shaped roller adjusting sheet without the micro-needle can replace the ring-shaped sheet to change the number of the micro-needle.

In the roller microneedle device disclosed in the patent document CN201220604693.1, the roller microneedle body is composed of a plurality of roller microneedle sheets, and the roller microneedle device has a simple structure, is convenient to use and easy to process, and when the roller microneedle device is used, different numbers of roller microneedle sheets can be selected according to different skin tissues or different treatment stages, so that the width of the roller microneedle body can be adjusted, and the roller microneedle sheet can be replaced after the microneedles on the roller microneedle sheet fall off, and is convenient to detach and cost-saving; in the layered replaceable roller microneedle tool disclosed in patent document CN201310045494.0, the layered roller microneedles of the invention are easy to detach and replace, and can replace microneedle sheets with different sizes and structures for different skin structures, and the integrated structure has a simple production process and low cost. However, there is no report on an improved roller microneedle which can adjust the length of a corresponding needle body according to clinical situations, so that a single sterile roller microneedle meets various clinical requirements, reduces the quantity of instrument consumables and reduces the treatment cost of patients.

In summary, there is a need for an improved roller microneedle which can adjust the length of the corresponding needle body according to the clinical situation, so that the single sterile roller microneedle can meet various clinical requirements, the number of the apparatus consumables is reduced, and the treatment cost of the patient is reduced.
