Abstract

The invention relates to the technical field of medical instruments, in particular to a posterior sclera minimally invasive crosslinking system. The problem that at present, a sclera surgical instrument capable of reducing sclera surgical wounds and preventing progressive myopia from spreading does not exist is solved. The system comprises a light source system, a liquid guide system, a telescopic system, a negative pressure system, a control system and a positioning system. The light source system comprises an ultraviolet blue light array light source or an ultraviolet blue light electroluminescent material; the liquid guiding system comprises a liquid guiding pump, a capillary tube for guiding liquid and a capillary tube for treating waste liquid under the control of a single chip microcomputer; the telescopic system controls a telescopic rod through a single-chip microcomputer to achieve minimally invasive surgery. The negative pressure system comprises an annular pipe and a fork pipe which are made of flexible materials, and is used for vacuumizing to form a negative pressure state so as to prevent reactants from seeping out; the positioning system enables an endoscope to be arranged on the membrane top layer so as to achieve the positioning function of the minimally invasive instrument. The device is good in flexibility and high in automation degree and safety, and minimally invasive operation can be achieved when a posterior sclera cross-linking method is carried out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a posterior sclera minimally invasive cross-linking system. Background technique [0002] High myopia is caused by excessive axial extension of the eye, so this involves the outer layer of the eye, the sclera. The sclera protects the intraocular structure and determines the final shape and size of the eye. The sclera serves as the anchor for the extraocular muscles and provides support for the ciliary muscle, which in turn assists in regulating the lens. Therefore, studying the sclera is the primary goal of therapeutic procedures to alleviate progressive myopia. Currently, scleral reinforcement surgery is the only clinical option for slowing scleral bulge, however, this surgery is associated with the risk of complications and the effect is not ideal. Therefore, it is necessary to develop a minimally invasive cross-linking system for posterior sclera, which can not only ...
