I KRUUSE Suture Suture needles The needle allows the placement of the suture and there are different kinds of suture needles n Welded needle, which means that the needle is already on the suture when opening the package. These needles are disposable and suture and needle are very easy to use. n Lose needles, where you thread the needle, and these needles can often be used several times. We classify the needles by n Shape (½ circle, 3/8 circle, compound curved or straight) n Type (cutting or round bodied with taperpoint, shown with a symbol) n Length (the curve of the needle measured in mm) Needle types Suture needles have different points and bodies. The choice of needle depends on the tissue it has to penetrate. 3/8 circle ½ circle Straight Compound curved Needle shape The shape of the needle is either 3/8 circle, ½ circle, compound curved or straight . Most of our ½ circle needles are round bodied and most of the 3/8 circle needles are reverse cutting. Micropoint spatula needle This type of needle is a special needle for ophthalmic surgery. The needle is flat and thin and has an extremely sharp cutting edge, which makes it suitable for penetration between the layers of scleral or corneal tissue. Reverse cutting needle Reverse cutting needles have a triangular shape in cross section, with the apex cutting edge on the outside of the needle. These features facilitate tissue penetration. Conventional cutting needle The conventional cutting needle has a triangular shape in cross section, and it cuts with the inner curve of the needle. Trocar point needle All KRUUSE trocar point needles are straight. The trocar point has a very sharp tip, and this type of needle is often used in the skin. Round bodied needles Round bodied needles are commonly used in soft tissue where separation of tissue fibres is preferred, rather than cutting the fibres apart. This would be preferable when suturing e.g. intestines, where the tissue closes tightly around the suture after passage of the needle. Round bodied taperpoint needle Taperpoint is the most common tip of round bodied needles. The taperpoint provides easy and tissue-preserving penetration by the needle. Round -bodied taperpoint extra needles This round bodied taper point needle differs slightly from other round bodied needles, as the cross section is oval instead of round. The outermost part of the tip (less than 0.5 mm) is drilled on three sides, i.e. working with this type of needle is a matter of preference, as it may appear to be sharper than traditional round-bodied taper point needles. Round bodied tapercut needle A round bodied needle with a cutting point; this needle gives good and easy penetration in tough tissues with little tissue trauma. KRUUSE© 02.2018 20192 www.kruuse.com
