Problems solved by technology

However, due to the insufficient length of the lacrimal plug, whether it is a degradable or a permanent plug, it cannot treat dry eye well.
[0004] In addition, the lacrimal ducts formed after acid-base burns are narrowed, and there are currently no mature treatment and prevention methods

Embodiment 1

[0030] Embodiment one, such as image 3 As shown, the resistance tube body 1 is provided with a cavity 5, on which the resistance core tube body 1 is provided with a microhole 4, by injecting medicine or nutritional factors into the cavity 5 from the head end 2 of the resistance core, etc. , medicines or nutritional factors slowly seep into the lacrimal duct through the micropores 4 and are absorbed by the eyes, which can better treat the acid-base burn symptoms of the eyes and dry eye syndrome.

Embodiment 2

[0031] Embodiment two, such as Figure 4 As shown, the tapered tip 3 has a hollow structure, the head of the tapered tip 3 is blunt and has an opening, and the resistance core tube body 1 and the resistance core head end 2 both have a hollow structure. This kind of canaliculus resistance core implantation, the canaliculus resistance core adopts a hollow structure to allow excess tears to flow out of the eyes through the hollow structure of the canaliculus resistance core, keep the tears in the eyes moderate, and have a significant effect in treating dry eye syndrome.

Abstract

The invention discloses a lacrimal ductile blocking core which comprises a blocking core tube body. One end of the blocking core tube body is provided with a taper-shaped tip. The other end of the lacrimal ductile blocking core tube is provided with a blocking core tip. The lacrimal ductile blocking core can be used for treating xerophthalmia conveniently, safely and stably, can prevent lacrimal passages from becoming narrow after acid and alkali burns, and can be taken out or planted into the lacrimal passages conveniently by tweezers.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a canaliculus resistance core for treating dry eye and preventing the narrowing of the lacrimal duct after acid-base burn. Background technique [0002] Dry eye syndrome refers to symptoms such as dry eyes, sore eyes, itchy eyes, photophobia, and vision loss caused by decreased tears or decreased lacrimal gland function. It damages the cornea, and corneal softening and perforation may occur in severe cases. [0003] An important method for the treatment of dry eye at present is punctal embolization. This method is to close the tear drainage duct by implanting a lacrimal plug. This method can preserve the natural tears secreted by the lacrimal duct itself and prolong the time that the tears stay on the ocular surface. However, due to the insufficient length of the lacrimal plug, no matter whether it is a degradable or a permanent plug, it cannot treat dry eye well. [0...
