Keiths are hand-held needles like Keiths, When you do away with of the purpose of needle holders it will be simplier, faster & more accurate in some applications. Hand-held needles, unlike those used with needle holder, do not require two 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, when the tissue has been reached. On the other hand, a curved needle's course is essentially predetermined by the shape of the curve as sin as the needle enters the tissue.
A straight needle isn't as mobile due to its inaccessible one by turning, as can occur when a curved needle slips in a needle holder's grasp. also, when your inserting a needle its not important to let go of it absolutely to regrasp for extraction. The straight needle, held between the thumb, index and middle fingers as it goes into the tissue, it may be grabbed once more by the thumb and index finger near the point, While you are maintaining control and pressure of the swage end with the side of your finger. The tip of the ring finger then acts much like the thimble-covered fingertip of a needle worker. Extracting, inserting & readying the needle for the next stitch thus becomes one continuous, motion of your right hand, with the left hand free for other manipulations. The major disadvantage of straight needles useful only on convex surfaces (e.g., skin) and some other organs cane be delivered out of the wound (for example tiny bowel).
If you choose to put wire sutures through a bone then you may want to use a Rochester awl, such as during closure of a sterna-splitting incision. to figure out a depth stop, use your index finger and thumb, & drilling or rotating the needle alternately clockwise and counterclockwise with small pressure, the needle can be inserted to a specific depth without any hazard of slipping more deep than intended. Extracting the awl with wire attached is also facilitated by a back-and-forth rotation of the surgical instruments. This motion means much less traction than needed with a steady pull.
