A Guide to Surgical Suture Manufacturing

Surgical Suture Manufacturing:

Paying close attention to detail and tight quality control procedures are essential when manufacturing surgical sutures. Surgeons choose the best suture materials for tissue approximation to maximize wound healing and scar aesthetics. The choice of sutures and needles varies widely across surgeons, and awareness of the numerous possibilities available enables doctors to form their preferences.

What is a Surgical Suture?

A surgical suture is an equipment used to hold bodily tissues together and round the edges of cracks following surgery or damage. A needle with a length of thread attached is used to apply sutures, and there are numerous varieties with different needle forms, sizes, and thread compositions.

Device Design and Other Characteristics of Suture

Medical threads called surgical sutures are used to repair wounds. They can be non-absorbable (need to be removed) or absorbable (the body breaks them down over time). Stainless steel suture needles are engineered to be robust, thin, and sharp. Depending on the surgical process, the design changes.   

Sutures’ strength, also known as tensile strength, or how well they withstand pulling structures, as well as whether they are absorbable, are important aspects to note.   

What are the Types of Surgical Sutures?

Based on absorbability, absorbable sutures do not require removal because the body breaks them down over time. Catgut, Polydioxanone (PDS), Polyglactin (Vicryl), and Polyglycolic Acid are a few examples. On the other hand, Non-absorbable Sutures can either be removed later or left in place permanently because they cannot be absorbed by the body. Silk, Nylon, Polyester, and Polypropylene are a few examples.  

Based on origin, natural sutures are sourced from biologically based natural fibers. Silk and catgut sutures are two examples. Whereas Synthetic sutures are produced through chemical synthesis. Examples include PDS1, Nylon, and Polyester.  

Lastly depending on Structure, Multifilament or braided sutures are made of numerous small threads that have been braided together as opposed to monofilament sutures, which are made of a single thread.
