Surgical Sutures: Performance, Development and Use

Abstract

The paper reports about different kind of sutures, their suitability and performance. An ideal suture should possess many characteristics such as - easy to handle, bio-compatibility, minimal tissue reaction, resistance to bacterial growth, adequate tensile strength and elasticity, knot security, strength loss versus healing rate of tissues. Selection of suture is often very complex for satisfying host of physical, mechanical and biological properties, and fulfilling contradictory requirements in varied applications. The paper develops an understanding about the selection of suture depending on the varied requirement. Past research work pertaining to the development of suture as reported in this paper, provides insight about the suitability of different surgical sutures and possible direction of future research.

Smart self-tightening surgical suture from a tough bio-based hyperbranched polyurethane/reduced carbon dot nanocomposite

“…3.9. Smart suture self-tightening behavior Self-tightening of a suture is highly significant in its application as this property is challenging in endoscopic surgery to close an open lumen or an incision by tying a knot [2]. It is particularly complicated to control the suture in order that the wound lips are pressed jointly under the right stress.…”

“…The methods of wound closure in orthopedic surgery to achieve accelerated recovery in patients have gained immense interest in recent times [1]. Accurate wound closure is aimed for rapid skin healing with minimum risk of complications such as wound infection or dehiscence which can cause morbidity and delayed discharge of the patient [2]. In this context, sutures are one of the most commonly used methods of wound closure post endoscopic surgery with a huge global market [2,3].…”

In this context, sutures are one of the most commonly used methods of wound closure post endoscopic surgery with a huge global market [2,3]. Sutures (natural/synthetic) are implantable medical devices which ligate blood vessels and hold body tissues together to assist and accelerate the healing process with negligible or no scar formation in a surgical procedure or an injury [4].…”

Natural Cellulose Fibers for Surgical Suture Applications

“…Natural materials, such as silk, have been used for the closure of wounds with satisfactory results. Still, they are more immunogenic than synthetic materials and thus increase the risk of the development of infections [17,30]. The main disadvantage of silk sutures is their multifilament or braided structure.…”

“…The main disadvantage of silk sutures is their multifilament or braided structure. This structural property increases the incidence of infection by five to eight times that of sutures comprised of monofilament materials [30][31][32].…”
