Surgical sutures properties

Polyglycolide was one of the first synthetic polymers used as a degradable surgical suture [122]. Fig. 8 shows the glycolide monomer and polymer structures. This aliphatic polyester is biodegradable and exhibits negligible toxicity when implanted in tissue. It is also possible to fabricate a strong fiber of this polyester with satisfactory mechanical properties.

The polymer can be spun into an elastic yam of very fine denier. It is also claimed to exhibit good mechanical properties for molding and compares favorably with commercial polyesters and nylons. Also, polycaprolactone was reported to be used in some medical applications in biodegradable surgical sutures and postoperative support pins and splints. Similar uses are also found for two other polyesters, poly (lactic acid) and poly(glycolic acid). The two polymers form from their cyclic dimers by cationic ring-opening polymerizations with the aid of Lewis acids ...

The previous chapter provided a general overview of the properties of materials used for surgical sutures and of the desirable characteristics of such materials. This chapter considers absorbable and nonabsorbable materials in greater detail, looking within each category first at natural materials, and second at synthetic materials. In the section on absorbable materials, natural materials reviewed are ...

Abstract The chapter describes procedures and materials used and results obtained from several important studies of the mechanical performance of surgical sutures and the chnical factors that influence their behavior. Key features of successful suture assembly are the material used, structure of the thread, surface treatment, knot strength, and security, the in vivo environment and compatibihty of the tensile properties of the thread with those of the tissues approximated during and after surgery. To improve suture success in terms, particularly, of knot performance, couphng of thermal and chemical energies in conjunction with mechanical interlacing have been experimented with. 

Despite having some limitations, barbed surgical sutures have become an established part of surgical practice (Cookson et al., 2011). This chapter reviews key aspects of barbed sutures, including their development, materials, design and manufacture. It also reviews testing and characterization as well as key properties. Finally, the chapter discusses the range of applications of barbed sutures.
