Description
Technical field
The present invention relates to a kind of devices for being used to prepare lacrimal bolt.
Background technology
Dry eyes, also known as cornea and conjunctiva xerosis refer to since the exception or tear fluid dynamics of tear quality and quantity are abnormal
Caused tear film is unstable and ocular surface injury, so as to cause a kind of disease of ophthalmic uncomfortable symptom.Tear is carried out using various emboluses
Tubule embolism is a kind of newer lacrimal passage sealing technique, by mechanical obstruction lacrimal passage, reduces the discharge of tear, re-establishes
The balance of ocular tear improves ocular environment, so as to the sings and symptoms of substantially reduced patient's dry eyes.
At present, the most commonly used embolism materials are silicon rubber or polyurethane, however the two mechanical strength and tissue phase
Difference is larger, while lacks bioactivity, and patient's implant site foreign body sensation is easily caused after implantation；And material is planted in hydrophobicity
It is fashionable to be assisted with lubricating oil, and be implanted into the period be usually no more than one month, therefore it is overdue need replacing, carry out second operation take
Phenomena such as going out, often generate secondary damage, leading to the reactions such as bleeding, inflammation, and then granulation hyperplasia occurs, is not suitable as implantation material
It implants.
Applicant has found in the course of the research, pHEMA hydrogel material good biocompatibilities, with tissue mechanical strength
Quite, compliance is good after implanting, and greatly reduces the foreign body sensation of implant site；And the hydrogel can absorb water from swollen
It is swollen, there is good self-retaining effect, be suitble to be chronically implanted.However silicon rubber or polyurethane are mainly processed by extrusion way
Type is not suitable for the molding of pHEMA gels.And there is partial gel to need uv-light polymerization aftershaping in gel embolism, tradition
Extrusion way can not more realize.
Therefore, how to propose it is a kind of be suitable for use pHEMA hydrogel materials to prepare the device of lacrimal bolt, make it just
In pHEMA gel formings, polymerization forming is carried out convenient for introducing ultraviolet light in the fabrication process, it appears particularly important.
