Description

A pen type trichiasis electrolyzer

technical field

The utility model relates to a pen type trichiasis electrolyzer.

Background technique

Trichiasis is a common and frequently-occurring disease in ophthalmology. Patients often have foreign body sensation, tearing and eye pain. Eyelashes rubbing against the eyeball for a long time can lead to conjunctival hyperemia, superficial corneal opacity, angiogenesis, corneal epithelial keratosis, and corneal ulcers. At present, for a small number of patients with trichiasis clinically: first, use trichiasis tweezers to pull out, but after pulling out, it will grow again like cutting leeks, and there is also the possibility of local infection; second, cut the trichiasis area under a microscope to remove hair follicles; The third is that the electrolysis method destroys the hair follicles of the trichiasis, and the trichiasis electrolysis instrument used clinically has problems such as large volume, high price, and unreasonable design of the needle end. Inverted trichiasis correction surgery is performed for those with more trichiasis or entropion. In clinical practice, for a small number of trichiasis, the effect of electrolysis treatment is the most ideal. Currently, there are two types of electrolyzers used clinically: one is a self-made electrolyzer, which is based on the principle generally recognized by the ophthalmology field. This method has been used for decades, but there are fewer and fewer users due to many inconveniences. The second is the trichiasis electrolysis instrument produced by the merchant. In clinical use, we found that it is large in size, high in cost, and the length of the needle body is not suitable. , There is no problem such as hand control or foot control switch. In view of the above problems, we designed a pen-type trichiasis electrolyzer, which adopts the principle generally recognized by the ophthalmology field. The charger comes from a charging device with an output voltage of 5V and an output current of 500mA for charging mobile phones. The pen is designed with a manual switch. Acupuncture needles are easy to install and disassemble, achieving the goal of one needle per person. The utility model has the advantages of simple structure, convenient operation, low cost and good effect.

According to the latest search by science and technology, as of December 12, 2022, there is no similar pen type trichiasis electrolyzer. There are four innovation points in the design of the utility model: one is to use a small mobile phone charger as a power supply, and its voltage output is stable, safe and reliable; The patient's normal tissue damage; the third is that the acupuncture needles are easy to load and unload, which can effectively avoid iatrogenic infection; the fourth is that the acupuncture needles are fixed reasonably, and when the needles penetrate the hair follicles of the trichiasis, they are relatively stable and the operation is accurate and fast.
