Everything You Need to Know About Surgical Sutures

Skin, an epithelial tissue, is the outermost covering of our body. It is a waterproof barrier that prevents the direct entry of microbes into our bodies. Whenever there is a cut or a laceration in the skin, it impairs the skin integrity. This leads to many complications such as skin infection, inflammation, etc. So, after a large cut or a wound, it is necessary to repair the skin to close the wound. Special medical devices used to repair these cuts or close the wounds are known as surgical sutures. Surgical suture is named so because mostly these sutures are used to close the skin site after surgery. The surgical suture consists of a thread and a needle that joins the body tissues. There are numerous surgical suture manufacturer companies around the world. Due to the increasing surgical procedures, there is a rise in the growth of surgical suture companies.

Types of Surgical Suture

There are many types of surgical sutures. Surgical sutures are broadly classified into Absorbable and Non-Absorbable sutures. 

Absorbable sutures: Absorbable sutures are not removed by the doctor. This is because they are absorbed by the body and then broken down by the enzymes present in our body. The time of absorption depends upon various factors such as the material of the suture, its location, and it also depends on the patient. 

Some commonly used absorbable sutures are Vicryl Rapide, Monocryl, Vicryl, and Polyglycolic acid sutures.

USES OF ABSORBABLE SUTURES: These sutures are mainly used for deeper tissues that heal quickly. Absorbable sutures are used for suturing in the urinary or biliary tract, tying off small vessels near the skin, and in small bowel anastomosis. They should not be used in cardiovascular or neurological procedures.

Non-Absorbable sutures: Non-absorbable sutures are the sutures that are to be removed by the doctor after a required period. They provide long-term protection to the tissues. They remain separated from the inflammatory processes of the tissues until they are manually removed from the skin.

Some commonly used Non-absorbable sutures are Nylon, Prolene, and silk.

USES OF NON-ABSORBABLE SUTURES: These sutures are mainly used in tissues that take time to heal. These are used to suture tissues such as fascia, tendons, abdominal wall, or vascular anastomoses. 

Sutures Can Be Further Classified Into Natural and Synthetic

Natural: Natural sutures are the ones that are made up of natural fibres such as silk and catgut, which are derived from the skin of sheep. They are rarely used because they elicit a tissue response. Out of these, silk sutures are used in surgical drains.

Synthetic: Synthetic sutures are composed of man-made substances such as nylon and polydioxanone sutures. They tend to be stronger than natural sutures. Synthetic sutures are used in ophthalmic and plastic surgeries.

Surgical Sutures Are Then Sub-categorized Based On Their Structure

Monofilament suture: As the name suggests, these sutures consist of a single strand. The risk of infection is lesser in this case, but they provide poor knot security, and it is not easy to handle them. 

Multifilament suture: In these sutures, various sutures are twisted together, and that’s why they are known as multifilament sutures. They have good knot security, are easy to handle but have a risk for infection.

There is a wide range of surgical suture companies in India. Orion sutures are one of the best surgical suture manufacturers in India. The surgical suture market in India has experienced a quick growth rate due to the increasing application of surgeries over the years.

Non Absorbable Sutures For Long-Term Support

Sutures are medical devices that are used to repair cuts in the skin tissue. They hold the tissues together when there is a breakage in skin integrity after an injury or surgery. They are usually thread-like. They are of different shapes, sizes and are used according to the type of cuts. Suturing is crucial for the healthy recovery of patients. Sutures are classified into various types. They can be Monofilament or braided. They can be natural and synthetic. They can be absorbable and non-absorbable. Absorbable sutures are the ones that are not removed by the doctor. They are digested by the enzymes present in our body. There are many types of absorbable sutures such as Gut, Poliglecaprone, Polydioxanone, and polyglactin. Non-absorbable sutures are removed by the doctor after some time. There are many types of Non-absorbable sutures, such as polypropylene, polyethene, and polyamide sutures

Non-Absorbable sutures

Non-absorbable sutures are the sutures that are to be removed by the doctor after a required period. They provide long-term protection to the tissues. They remain separated from the inflammatory processes of the tissues until they are manually removed from the skin. Some commonly used Non-absorbable sutures are Nylon, Prolene, and silk. These sutures are mainly used in tissues that take time to heal. These are used to suture tissues such as fascia, tendons, abdominal wall, or vascular anastomoses. 

Types and their Advantages & Disadvantages:

Silk sutures

These sutures are being used for a very long time. Silk sutures are synthetic man-made sutures. Silk Sutures are best for use in Dental Surgery, It is also available in reels of 25meters or 10meter packing

Advantages: Silk sutures have excellent knot security. They are easy to be handled; therefore, they can also be used as a temporary suture during surgery. They rarely elicit a tissue reaction. They are soft and comfortable. 

Disadvantages: Silk tends to enter the tissues, which makes it painful to remove. It has low tensile strength, so it can break under high tension. 

Stainless steel wire sutures

These are the sterile non-absorbable sutures used widely in abdominal wound closure and orthopaedic procedures. 

Advantages: They are inexpensive, soft, and malleable. The main advantage of these sutures is that they do not promote infection. They are strong and flexible sutures.

Disadvantages: The stainless-steel wires are springy in nature.

Polypropylene sutures

They are synthetic non-absorbable monofilament sutures.

Advantages: These sutures provide long dermal support. They elicit less tissue reaction and are used in skin and percutaneous as well as subcuticular pull-out closures. 

Disadvantages: They have poor knot security. 

Polyethylene sutures

These sutures are non-absorbable surgical sutures. 

Advantages: These are soft and gentle, so they can be used on tissues easily. They have high knot security.

Polyamide sutures

Polyamide sutures are synthetic surgical sutures. It is composed of caprolactam.

Advantages: It has low tissue reactivity. It is widely used for general soft tissue approximation. It can also be used in cardiovascular and neurological procedures. 

Disadvantages: It is difficult to handle and to tie. 

Out of these non-absorbable sutures, polyamide nylon sutures in India, Black Braided Silk are soft and gentle and have minimal tissue response. Multifilament polyamide sutures are best for skin approximation.
