HOMESurgical InstrumentsINNOVATIONSM-1015 Visco-spatula Knife, Hanemoto: standard size / M-1016 long size / M-1017 Hand piece
This is a new instrument designed for use during manipulation of the proliferative Membrane in proliferative diabetic retinopathy(PDR).It consists of a handpiece, a 23 gauge cannula and a spatula knife at the tip.
How to use the Visco-spatula knife(VSK):
The VSK and the cannula are attached to the end of the handpiece at one end, while the syringe containing a viscoelastic material is attached to the other end,through an extension tube. The VSK is introduced underneath the proliferative membrane.
The operator then dissects the vascular connection of the membrane using the tip of the VSK during viscodelamination while the assistant injects the viscoelastic material through the cannula.
The advantage of the visco-spatula knife is that it can reduce the risk of retinal break due to less excessive elevation of the focal retina because of prior dissection of the vascular connection of the membrane. In addition, the decreased need to change instruments during the operative process reduces the possibility of a vitreous incarceration due to frequent manipulation at the port.
The Visco-spatula knife has 2 sizes: a standard size and a long size.
The standard size is preferably used for PDR with limited posterior vitreous detachment and moderate membrane while the long size is more useful for PDR with tractional retinal detachment and strong membrane with retinal break.
The handpiece for Visco-spatula knife is 8mm in diameter,76mm in length and approx.15g. in weight of viscoelastic material in use to the least possible amount, 23G pipe is built in getting through the handpiece.
