General Spesifications of Surgical Stitching MaterialsSurgical stitching materials are used to provide tissue support during wound healing process through approximation of two edges of the wound. Although wound healing is a natural process, severed damages need to be approximated via surgical suture materials. Surgical thread is the most common material for wound closure for a long time. There are two significant factors affecting surgical stitching process: Surgical needle and surgical suture
Surgical NeedlesSurgical needle is required for penetration of surgical thread into tissue. Minimal tissue trauma is mostly expected from a surgical needle during carrying of surgical suture through tissue. Although eyed needles were used in the past, atraumatic needles have been widely used now since eyed needles result in big gaps in tissue during tissue penetration and suture is pulled strongly through tissues. Therefore, tissue trauma is seen at minimum level with atraumatic needles. Ideal surgical needle should have following specifications:
- It should be made of high quality stainless steel material.
- It should be stable when it is held by needle-holder.
- It should not cause any tissue trauma during tissue penetration.
- It should be rigid enough not to bend but should be flexible enough not to be broken.
- It should have corrosion resistance and be sterile in order to prevent tissue from entrance of foreign materials and microorganisms, respectively.
- It should have smooth surface and should have coating material to penetrate into tissue easily. Needle surface should have resistance to corrosion.
- It should have similar diameters with the suture attached to it.
