What is a suture?
A suture is a surgical equipment used to bind together the edges of a surgical incision or wound. Sutures are widely used by medical professionals on patients’ post-surgery or after sustaining an injury.
Sutures are used by a range of medical professionals including General Practitioners, Plastic Surgeons, Dermatologists, Orthopaedic Surgeons, Oral Surgeons, Dentists, Veterinarians (Vets) and many more.
How a Suture is Structured
A suture is made from 2 main components. The needle and the thread. Needles come in many different configurations with the most popular needle used being a reverse cutting needle. This is where the needle has a cutting edge on the under/back side of the needle. Threads also vary depending on the application. These can typically be categorised into absorbable or non-absorbable.
Suture Needle Types
Taper-Point – Taper-point needles are suited to soft tissue. They dilate rather than cutting.
Suture Thread Types
Non-Absorbable Suture Threads
There are many different non-absorbable suture threads that have been produced. Here are the most widely used threads available.
- Polyamide 6 – Polyamide 6 is a synthetic monofilament thread. Polyamide 6 sutures are developed to have great handling characteristics and excellent knot security.
- Nylon – Nylon is a natural monofilament thread.
- Silk – A braided natural suture thread.
- Polyester – Polyester suture threads are a synthetic thread that is braided.
Absorbable Suture Threads
Like non-absorbable threads, absorbable threads are diverse. Here are the most widely used absorbable threads available.
- Poly (Glycolide-co-Caprolactone) (PGCL) – High tensile strength, smooth monofilament and good handling and knotting characteristics. Is available in dyed (violet) or undyed thread colour.
- Poly(Glycolide-co-lactide) - Excellent biocompatibility, great knot security and predictable absorption make Poly(Glycolide-co-lactide) very popular for closure of internal tissue
- Poliglecaprone – Poliglecaprone is a synthetic monofilament made of glycolide and epsilon-capralactone.
- Polyglactin – Coated, braided absorbable monofilament suture.
- Gut suture – Rapid and variable absorption rate. It has good handling characteristics but poor knot security.
