Let’s Break The Jargons – Not Only Doctors But Everyone Needs To Learn About The Basics Of Needles!

In view of the worldwide coronavirus pandemic, health care departments need contingency planning. However, there were many patients who had to undergo some kind of surgery. But it was not easy to do all this during these hard times.

Doctors and health care staff need to take precautionary measures. For instance, the very first thing was to sterilize all the surgical instruments. You will get to know all about the needles in this blog.

Surgical needle – What is it?

However, it Is not possible to demeanor any surgery without surgical needles. Yes, it is so right. Placement of suture in tissues is not possible without using surgical needles. These needles are always designed in a way to carry the minimal residual material.

Which material is suitable for the surgical needles?

Most commonly, stainless steel is used for the manufacturing of surgical needles. They have outstanding resistance to corrosion. Because stainless steel contains 12% chromium, so it forms a thin layer of chromium oxide.

Characteristics of surgical needles:

Following are the characteristics of the needles.

  • They are slim but never compromises on its strength.
  • With minimal trauma, they can carry suture material through the tissues.
  • They are sharp to enter the tissue without much resistance.
  • They are very rigid.
  • There are no chances of breakage during surgery.
  • They are resistant and keeps all the microorganisms away from entering the wounds.

Types of surgical needles:

Well, there are different types of needles. Few types are as under;

  • Straight needle

Straight needles are commonly used for surgeries where sutures can easily be done with the help of hands. You can use them for the microsurgery of nerves and vessels. However, there are two examples for the straight body needles. The first one is the Keith needle that you use for abdominal wounds or skin closures.

However, the other one is the Bunnel needle.  It is in use to repair tendon or gastrointestinal.

  • Half curved needle

The half-curved needle is used for skin closures. Furthermore, it is hard to handle this type of needle for the straight portions of the body.

  • Curved needle

In curved needles, a predictable turnout is predicted. Moreover, this type needs less space than straight ones. There are different curvatures accessible for this type.

  • Compound curved needle

This type is best for anterior-segment ophthalmic surgery. Plus, it helps the surgeons to take precise bites of the tissues. It has 80% curvature at the tip and 45% at the remainder of the body. This type of needle is also suitable for the vessel approximation in microvascular surgery.

  • Taper point needles

This type of surgical needle pierces the tissue without cutting it. They are best for minimal trauma treatments. Soft tissues must be treated with these taper point needles.

  • Cutting edge surgical needles

This type of needle can easily pass through the tough and hard tissues of the body. Moreover, they are best for treating dermal issues and for suturing the skin.

  • Reverse cutting needle

This needle comes with a cutting surface. They are ideal for tough tissues like tendons. They reduced the risk of cutting through stitches.

What are Sections/ parts of surgical needles?

 A surgical needle compromises of the three different parts. However, the first one is the body, another one is a point, and the last one is the swage.


 The body is the midportion of the needles. Plus, the needle holder grasps this portion during the surgical procedure.

Plus, it is necessary to have the body as close as it can be to the suture’s diameter. This will minimize the chances of leakage or bleeding from the body.


Well, now this is the most sharp part of the needle. It is used to penetrate the tissues. However, this is the most important part of the needle and needs to be sharp. However, the point includes the following.

  • Taper point
  • Cutting needles
  • Blunt point needles
  • Conventional cutting edge
    Surgical Cutting Scissors


 Now, this is the point where suture material is attached with a needle. Moreover, this is the thickest point in the whole needle.


Qualities of a good needle:

Needles and all the other surgical equipment need to be of high-quality. It is not possible to compromise on their quality. However, the following characteristics are a must for good quality needles:

  1. High-quality stainless steel should be used in it.
  2. Should have the smallest diameter
  3. It should easily transmit the suture material without giving much pain to the patient.
  4. It should be sharp enough.

Surgical needles are the most important health care product. So, you have to put special attention to their manufacturing

Needle length:

There are so many needle lengths available. You have to pick the one you find more suitable. Following are the lengths.

6mm, 8mm, 18mm, 22mm, 30mm, 35mm, 40mm and the last one is 50mm.
