The choice of needle shape is frequently governed by the accessibility of the tissue to be sutured and normally the more confined the operative site the greater the curvature required. The basic shapes involved are:
Needles Based On Tips
Taper PointThese don’t have sharp edges. They have conic bodies getting sharper towards the end. These are used on tissue that show less resistance to the needle. |
 |
 |
|
Square Body, Taper PointThese don’t have sharp edges. They have conic bodies getting sharper towards the end. The edge is square to give a more resistant body to the needle. |
 |
 |
|
BluntThese don’t have sharp and puncture property. These needles are used for sensitive and parenchyma tissues such as liver and kidney. |
 |
 |
|
Reverse CuttingThis needle is also called outer sharp which is a triangle-tipped needled with two sharp edges. Premium and Premium Thin Line versions are filed by hand and generally used in plastic surgery. Premium Thin Line is thinner than Premium. |

Inside CuttingThis needle is also called inner sharp which is a triangle-tipped needled with two sharp edges. Premium and Premium Thin Line versions are filed by hand and generally used in plastic surgery. Premium Thin Line is thinner than Premium. |

DiamondAlso called head sharp, this needle is a straight bodied needle with sharp edges and edged conic height. These are often used for hard tissues. Premium version is filed by hand. |

SpatulaThis needle has a flat body and becomes thinner towards the end. It is often used for ophthalmic surgery. |
 |
 |
|
LancetIt looks like a spatula needle. But the tips are curved rather than being parallel to the body. The edges of the top surface are sharp. It is used for ophthalmic surgery. |
 |
 |
|
CC NeedleThis is the combination of sharp and round needle properties. The three sharp edges don’t connect with the round body. The sharp edges make a single-type cutting movement. |
 |
 |
|
TapercuttingThis is the combination of reverse sharp and round needle properties. The three sharp edges are far from the tip. This is mixed with the round body. All three edges are sharpened to ensure a single-type cutting movement. |
 |
 |
|
TrocarTrocar needle has a strong and sharp edge. This property is designed for the needle to easily penetrate to thick tissues. |
 |
 |
|
Square Body TapercuttingThe body is squared to give a more resistant needle structure than the taper cutting needle. |
