Surgical needles are used for suturing and stitching soft biological tissues. Their task is to pass medical suture material through tissue with minimal traumatic effect. Surgical needles must be as sharp as possible in order to pierce tissue with minimal resistance, rigid and flexible so as not to break under bending. They are made from medical grade stainless steel, remaining sterile and not susceptible to corrosion by water.

Surgical needles - main features

Traditionally, surgical needles consist of three parts - a dovetail-shaped eye, a body and a piercing part. Over half of modern needle models are classified as atraumatic - they come with a thread attached to the needle at the factory. The atraumatic structure of the needle allows us to minimize the possibility of causing damage to the tissue being sutured, since the diameter of the needle matches the diameter of the suture material as accurately as possible. Atraumatic models are disposable, while traditional ones are reusable, but repeated sterilization significantly reduces their piercing properties.

Surgical needles - main types

According to their shape, needles are classified into the following types:

  1. Punching needle - has a round cross-section and a cone-shaped piercing tip. Used in surgery to connect tissues of internal organs with a homogeneous structure, muscle tissue and mucous membrane;
  2. Cutting - has a triangular shape in diameter. Depending on the orientation of the third face, it can be straight or reverse. Cutting models are used to connect the skin;
  3. Stab-cutting - is a combination of cutting and piercing models. Used to connect hard tissues, such as blood vessels with calcifications;
  4. Lancet-shaped - a needle that is used in microsurgical and ophthalmic operations. It has a trapezoidal cross-sectional shape;
  5. Blunt-ended - have a round shape with blunt ends.

The most common are the first three types of surgical needles. In addition to this classification, there are two types of operating needles - straight and curved. The level of needle curvature is indicated in fractions of a circle, for example, 2/8 or 4/8. The closer to the bottom of a narrow wound the tissue is sutured, the larger the circumference of the surgical needle should be. For example, when working in depth, it is better to choose a needle with a ½ or 5/8 curvature, while surface work, for example, when joining skin tissue, requires a needle with a 1/4 curvature.

Two more important characteristics of a surgical needle are its length and diameter in millimeters. The thinnest models are used in microsurgical and ophthalmological operations, and the thickest ones are used during the connection of tissues of the sternum or abdominal cavity.
