The long, narrow leaf of some conifers.
A thin metal instrument with a sharp point at one end and a hole at the other for attaching a thread, used for sewing up surgical incisions.
The hollow pointed end of a hypodermic syringe, or the syringe itself.
A leaf that is needle-like in form most commonly used for the leaves of pines (Pinus).
A slender sharp-pointed instrument used for a variety of purposes. Needles used for sewing up tissue during surgical operation are of various designs, for specific operations, and are equipped with an eye for threading suture material. Hollow needles are used to inject substances into the body (in hypodermic syringes), to obtain specimens of tissue (see biopsy), or to withdraw fluid from a cavity.
A pointed instrument for stitching, ligaturing, puncturing, or cannulating. It may be straight, half curved, full-curved, semicircular, double-curved (sometimes called “S-” or sigmoid-shaped), double-ended, sharp or blunt-tipped, solid, or hollow. Cutting edge and round point are the two classifications of needles. Cutting edge needles are used in skin and dense tissue, while round point needles are used for more delicate operations, especially on soft tissues. When a needle is used for stitching, the suture material may be attached via an eye, french eye, or more commonly, a swedged-on which is easily detachable.
