Surgical Needles

Surgical Needles - There are a variety of needles for wound closure. Curved needles have two basic configurations; tapered and cutting. For wound and laceration care, the reverse cutting needle is used almost exclusively. It is made in such a way that the outer edge is sharp so as to allow for smooth and atraumatic penetration of tough skin and fascia. Tapered needles are used on soft tissue, such as bowel and subcutaneous tissue, or when the smallest diameter hole is desired. Typically, surgical needles are made from stainless-steel. Read about sutures - Sutures Surgical Needles Surgical Needles Parts of Needle Three parts - Eye, Body and Point Eye of Needle The eye is where the suture attaches to the needle; this can be an actual needle eye, where the string threads via or a factor where the suture thread obtains swaged on to the needle (most modern-day needles are of this latter type). Most skin closure sutures are curved, and normally 3/8 of a circle. The surgical needle enables the placement of the suture within the tissue, carrying the material through with minimal recurring injury. Body of Needle The needle body or shaft is the region grasped by the needle holder. Needle bodies can be round, cutting, or reverse cutting: Round bodied needles are utilized in friable tissue such as liver and kidney. The needle factor acts to pierce the tissue, beginning at the topmost factor of the body and also running to the end of the needle, and also can be either sharp or blunt. Blunt needles are made use of for abdominal wall closure, and also in friable tissue, and also can potentially lower the risk of blood birthed virus infection from needle stick injuries.Sharp needles pierce and also spread tissues with minimal cutting, and also are made use of in areas where leakage should be protected against. Tip or Point Of Needle Among needles, there are different types based upon the needle tip, generally cutting or taper needles. Cutting needles have a tip with three sharp sides, with a standard cutting needle having the cutting surface area inside the needle as well as a reverse cutting needle having it outside of the needle. Reverse cutting needles are frequently used for stitching skin. Cutting Neeldes Cutting needles are triangular in shape, and also have 3 cutting sides to pass through challenging tissue such as the skin and also sternum, as well as have a cutting surface area on the concave side. Reverse cutting needles have a cutting surface on the convex edge, as well as are ideal for challenging tissue such as tendon or subcuticular sutures, and have minimized risk of cutting through tissue. Surgical Needles Round Needles Taper needles are rounded and can be either sharp or blunt. They work by puncturing the tissue without sufficing, basically spreading out the tissue as it goes through it. These benefit soft as well as fragile tissues. The suitable surgical needle ought to be stiff sufficient to stand up to distortion, yet flexible enough to bend prior to breaking, be as slim as feasible to minimise injury, sharp enough to penetrate tissue with very little resistance, and also be secure within a needle holder to permit accurate placement. SURGICAL INSTRUMENTS in Emergency Ward - It is not necessary to have large numbers of instruments for emergency wound care. Wounds and lacerations can be managed with the following instruments: NEEDLE HOLDERS: Needle holders come in various sizes and shapes, but for most lacerations a standard size 4" will complete the task. For larger, deeper wound closures a larger needle and needle holder may be required.FORCEPS: Grasping and controlling tissue with forceps is essential to proper suture placement.However, whenever force is applied to skin or other tissues, inadvertent damage to cells can occur if andimproper instrument or technique is used. Be gentle when grasping tissue, and never fully close the jawson the skin.SCISSORS: There are three types of scissors that are useful in minor wound care.a. IRIS SCISSORS: Iris scissors are predominantly used to assist in wound debridement and revision. These scissors are very sharp and are appropriate in situations that require very fine control. They are very delicate and are not recommended for cutting sutures. However, when very small sutures require removal they can be use.b. DISSECTION SCISSORS: Used for heavier tissue revision as necessary for wound undermining.c. SUTURE REMOVAL SCISSORS: Standard 6-inch, single blunt-tip, suture scissors are most useful for cutting sutures, adhesive tape, and other dressing materials. Because of their size and bulk, these scissors are very durable and practical.HEMOSTATS or Mosquito Forceps (What we use to call them !): Hemostats have three functions in minor wound care: clamping small blood vessels for hemorrhage control, grasping and securing fascia during debridement, and are an excellent tool for exposing, exploring and visualizing deeper areas of the wound.KNIFE HANDLES AND BLADES: The knife handle holds the blade and is used in the debridement and excisions during wound revision. Common blades are the #10 blade (used for large excisions), #15 blade (small, versatile and well suited for precise debridement and wound revision), and the #11 blade (ideal for incision and drainage of superficial abscesses and the removal of very small sutures).
