KRUUSE I Suture Needles All needles are high quality stainless steel from a highly recommended Japanese supplier. We recommend use of needles with welded suture to minimize wound trauma due to double thread. Needle shape The shape of the needle is either 3/8 circle, ½ circle, compound curve or straight . Most of our ½ circle needles are round bodied and most of the 3/8 circle needles are reverse cutting. 3/8 circle ½ circle Compound curved 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. 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 needle. 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. www.kruuse.com I Round bodied needles Round bodied needles are commonly used in soft tissue where separation of tissue fibers is prefe rred, rather than cutting the fibers apart. This would be preferable when suturing e.g. intestine, where the tissue closes tightly around the suture after passage of the needle. 13 · 325 Trocar point needle All KRUUSE trocar point needles are straight.
