The first true hypodermic syringe was created by Alexander Wood in 1853. He modified a regular syringe, which at that time was used for treating birthmarks, by adding a needle. He then used this new device for introducing morphine into the skin of patients who suffered from sleeping disorders.
In fact there were many cultures including Egyptians, Greeks and Romans that routinely used stitches or sutures in their medical treatment of wounds and surgical procedures. The first types of needles were primitive and were made of fine shards of bone or metals. This meant that the suture material tended to be coarser and heavier and was most likely originally made from plant materials. The first people to actually use surgical sutures are believed to the ancient Egyptians.
