Description

Bent telescopic handle type flute needle for presbyopic vitreoretinal surgery

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a bent telescopic handle type flute needle for a monocular ophthalmosphere vitreoretinal operation.

Background

The vitreous body is colorless transparent colloid and is positioned behind the crystalline lens, filled between the crystalline lens and the retina and filled in the cavity behind the crystalline lens, and has the functions of refraction and retina fixation. In the surgical treatment of vitreoretinal diseases, a gas-liquid exchange procedure is typically involved which requires a cartesian needle to aspirate the posterior pole vitreous humor or subretinal fluid.

For the eyeball with normal axis, the flute needle can smoothly extend into the posterior pole part of the eyeground to discharge the liquid under the retinal nerve epithelium layer through gas-liquid exchange. However, in the case of a longaxis eyeball caused by high myopia, when the cartesian needle head penetrates into the posterior pole part, due to the reduction of the included angle between the needle head and the axis of the eye, the needle tail part and the cartesian needle rod part outside are easy to touch a non-contact wide-angle lens (such as a Resight lens, the distance is about 4mm from the top to the bottom of the cornea) above the cornea, so that the visual field of the fundus operation is not clear, and the gas-liquid exchange is influenced. Meanwhile, the existing whistles adopt the natural atmospheric pressure of the external environment to construct a negative pressure environment to absorb liquid in the eyeball, and the whole absorption process is unstable due to uncontrollable external factors, so that the operation quality is poor, and even secondary damage is caused to the eyeball.

Therefore, it is necessary to develop a curved handle type cartesian needle for the prolate axis eyeball vitreoretinal surgery.
