 The two instruments that I am holding in my hand, these are the straight and the curved Suchatang Forsep. The straight Suchatang Forsep is held in the left hand during ophthalmic surgery and the curved Suchatang Forsep is held in the right hand. The right Suchatang Forsep is used to tie the knot. The left is used to hold one end of the Suchatang material. Apart from the obvious difference, namely one is straight, the other is curved, let's talk of some similarities which both of them have together. I will use the straight Suchatang material to demonstrate the similarity. If you were to take a look at the tip, we notice that the tip is fine-limbed. It is non-toothed. However, a closer look at the tip will demonstrate that on the inner surface of the tip there is a shallow ridge and the portion distilled to that has got a slightly flattened and a slightly rough surface. Therefore, when I apply pressure to the prongs of the Forsep, the two flat surfaces come together and they gently grip the fine Suchatang material without breaking or tearing them. The same characteristics apply to the curved Suchatang material also. When I apply pressure, it holds the tip of the Suchatang material. The left one holds the straight and the right hand holds the curved. It is used to tie the knot in eye surgery. Stay tuned for the next video.
