Lacrimal ductule embolization pusher

Abstract

The invention discloses a lacrimal ductule embolization pusher which is composed of an import head and a pusher handle; the pusher can be detached into four parts: an implant tube, an implant cannula,a pusher handpiece and a putter; the import head consists of the implant tube and the implant cannula that capable of holding various types of lacrimal ductule embolization; the pusher handle consists of an elongated rounded rectangular pusher handpiece and an internal putter (the putter front end is a slender push pin); the two parts are fixed by the connection between the implant cannula and the pusher handle, and the snap groove of the implant tube and the top of the cannula; at the same time, the implant tube is fixed. The invention can safely and effectively implant various types of lacrimal ductule embolization into the lacrimal ductile in a pre-installed or a non-preloaded mode. The position and depth of the lacrimal ductule are fixed, which not only reduces the operation difficulty, reduces the operation risk, but also improves the implantation efficiency. The invention is mainly used for the treatment of lacrimal ductule embolization of moderate-to-severe water-deficient dryeye.

Description

technical field [0001] The invention relates to a lacrimal canaliculus embolism injector, which can safely and effectively implant various types of lacrimal canaliculus embolisms into the lacrimal canaliculus, and is mainly used for the lacrimal canaliculus embolization treatment of moderate to severe water deficiency dry eyes. Background technique [0002] The incidence of dry eye in my country is about 21% to 30%. It is a kind of disease that causes eye discomfort symptoms due to tear film instability and ocular surface damage caused by abnormal tear quality and quantity or abnormal tear hydrodynamics. . Among them, water-deficient dry eye refers to damage or dysfunction of the lacrimal gland, and insufficient tear secretion, which causes dry eye. Dry eye patients often have symptoms such as fatigue, dryness, burning sensation, sore eyes, vision fluctuations, red eyes, itchy eyes, photophobia, tearing, etc. In severe cases, it can also cause corneal infection, corneal neov...

Problems solved by technology

[0008] However, most of the canaliculus plugs currently used in clinical practice are non-prefabricated. Due to the small size of the canaliculus plug (the diameter is generally 0.4mm or 0.5mm, and the length is generally not more than 6mm), improper operation can easily lead to contamination and drop of the plug. And because most of them are imported from abroad, the price is expensive, which will bring huge psychological pressure to the operator; at present, the clinical practice mainly depends on the implantation of tweezers, which is easy to cause fatigue and low efficiency when operating for a long time

In addition, there is no uniform standard for the position and depth of the implantation of the lacrimal canaliculus, and it is basically operated by referring to the instructions of each product
