Description

FCB clamping forceps

Technical Field

The invention relates to tweezers, in particular to FCB (fiber-channel-B) clamping tweezers.

Background

A Foldable artificial Vitreous Body balloon (FCVB) is an innovative product developed and produced by guangzhou satellite video biotechnology limited (refer to patent CN101386203B), which consists of a balloon, a drainage tube, a drainage valve, etc., and a base material is made of imported silica gel which is safe to be used in human Body for more than 20 years, is used for intraocular implantation, treats severe retinal detachment which cannot be treated with the existing Vitreous Body substitute, and has been widely used clinically at home and abroad; meanwhile, the FCVB can be implanted on the surface of the sclera as a Foldable Capsule (FCB) to press against the sclera by filling physiological saline to assist in freezing or laser sealing the fissure and play a role in treating the Rhegmatogenous Retinal Detachment (RRD).

At present, no special clamping forceps are used when the FCB is implanted to treat RRD, and the universal micro-operation forceps are sharp at the tail end and easy to damage the FCB, so that the waste of resources is caused, and the treatment cost is also improved due to the high price of the FCB; meanwhile, the retinal hole position cannot be positioned while the FCB treatment RRD is implemented.

Therefore, there is a need for FCB holding forceps that facilitate preventing FCB damage and that can locate retinal tear locations at the same time as FCB implantation.
