Intraretinal fluid drainage device

Abstract

The invention relates to an intraretinal fluid drainage device, belonging to the technical field of devices for ophthalmic surgery, including a drainage body having a drainage channel and an injectionneedle movably disposed axially within the drainage channel, wherein the drainage body comprises a piercing part and a gripping part which are integrally arranged and respectively sleeved on an injection needle body and a needle handle, at one end of the needle tip of the injection needle, the pierce part is provided with a ring-shaped light emit device and an image sensor, the gripping part is provided with a power supply device and a data socket; the power supply device and the image sensor are communicated with each other through wires preset in the drainage body, the data socket and the image sensor are communicated with each other through optical fibers preset in the drainage body, and the image processor and the display are communicated with each other through data wires, and the image processor and the data socket and the display are communicated with each other through data wires. The invention provides a composite structure of a drainage body and an injection needle, and an annular lighting and imaging device, thereby realizing the design purpose of safely extracting retinal internal fluid.

Description

Technical field [0001] The present invention relates to the technical field of devices used in ophthalmic surgery, in particular to a device used to draw out intraretinal fluid. Background technique [0002] Retinal detachment is high. After scleral cerclage or external compression, there is still more intraretinal fluid in the hole, which affects the closure of the hole and choroid. At this time, intraretinal fluid drainage should be performed. The prior art basically uses a syringe needle to puncture and release fluid. In order to prevent puncture from damaging the retina, the puncture must be punctured in a tangential direction. In the puncture process, a little force is used to cause the puncture to be too deep and cause damage to the retina. Therefore, medical technology is highly required. [0003] If a special drainage tool is proposed, lighting and imaging devices are set on the syringe needle, and the entire puncture process is video-monitored, which can increase the accur...

Problems solved by technology

[0005] In view of this, the object of the present invention is to provide a drainage device for intraretinal fluid, which can monitor the puncture operation throughout the whole process through lighting and imaging devices, which can increase the accuracy of puncture, thereby significantly improving the safety of drainage, so as to solve the problems in the prior art. Poor accuracy and insufficient security due to lack of special tools
