Hand-held straight needles, such as Keiths, When you get rid of the purpose of needle holders it will be easier, in some cases it faster and more precise. Unlike needle holders, hand-held needles, don't need both hands to reposition the needle for the next stitch. A straight needle will give more accurate opportunity to direct its point without breaking or bending, once the tissue has been entered. On the flip side, a curved needle's course is essentially preprogrammed by the shape of the curve as sin as the needle enters the tissue.
A straight needle can never change its attitude to an inaccessible one by turning, as can occur when a curved needle slips in a needle holder's grab. also, when your inserting a needle its not significant to let go of it completely to regrab for extraction. When the straight needle goes through & enters the tissue held between the index, thumb & middle fingers, can be regrasped by the thumb and index finger near the point, while still maintaining pressure and control of the swage end with the side of the ring finger. The tip of the ring finger then acts a great deal like the thimble-covered fingertip of a needle worker. Extracting, inserting & readying the needle for the next stitch thus becomes one continuous, useful movement of the right hand, with the left hand free for other manipulations. The main disadvantage of straight needles useful only on convex surfaces (e.g., skin) and some other organs cane be delivered out of the wound (e.g., tiny bowel).
A Rochester awl may be used to put wire sutures through the bone, such as during closure of a sterna-splitting incision. Using the thumb and index finger as a depth stop, and with minimal pressure start drilling or rotating clockwise and counter-clockwise switching back & forth, You can then insert the needle to the depth that you'd like without any risk of slipping deeper than what you want. To extract the awl with wire attached is done by a back and forth of surgical instruments. This motion gives less traction than needed with a steady pull.
