What Are Sutures And Their Different Types?

Sutures And Their Different Types

Sutures are special type of surgical threads used to repair cuts and close incisions from surgery. Commonly called stiches, they are sterile in nature and help hold skin and internal organs together after surgery. They are also used in holding together blood vessels and other tissues of the human body resulting from surgery, injury or incision. They are an extremely vital medical device for wound closure, and clinics often have them for wound healing purposes. Sutures are strong enough to hold together tissues and organs until the healing is done and body regains the power to withstand stress without any mechanical support.

Types of sutures

Sutures are of many kinds and they come with unique properties and suit various uses. They can basically be classified into two groups –

Sutures And Their Different Types

  • Absorbable sutures

  • Non-absorbable sutures

As the name suggests, the absorbable variety is one that breaks down in the body after a specific time period. No medical help is thus required to take these sutures out of the body as they degrade as the wound or incision heal.

On the other hand, the non-absorbable variety is created with the goal to not dissolve in the body and a surgeon is needed to get them out of the body once the wound or incision is healed.

Despite their classifications and types, all sutures tend to be strong so that they don’t break that easily and help in wound healing. They are non-toxic in nature else their presence in the body might create a lot of problems.

Similarly, good-quality sutures are flexible so that doctors can tie and knot them with effortless ease. They must be hypoallergenic to ensure no adverse reactions in the body. What’s more, they are created in a manner to not let fluids enter the body and cause infections.

Properties and uses of sutures

We know sutures have a big role to play in wound closure and they help immeasurably in wound healing as well. All this is done with the help of properties of these sterile threads that have varying uses as well.

Let’s look at properties and uses –

  • It’s the surgeons who decide whether to use the absorbable or non-absorbable variety of threads based on the nature and intensity of wounds

  • The absorbable variety of threads are often used and placed internally so that their removal is not required

  • The non-absorbable types however are often placed externally so that they can be removed easily in minutes

  • Sutures are made of specialized materials in case they have to be used for sensitive environment such as the heart and the bladder so that they not ever dissolved

  • There are monofilament and multifilament types as well categorized as per the material structure

  • While the multifilament sutures deliver superior knot security, the monofilament ones enable better passage through tissues

  • Sutures are also classified based on the type of raw material used so we have natural and synthetic varieties

  • The sutures made of silk and catgut are considered natural while the rest fall in the synthetic category

  • So, take care with sutures India and add value to your profession
