An electrosurgical pencil, also called diathermy pencil, electrocautery pencil, is a handheld surgical instrument used in electrosurgery. In electrosurgery, the medical procedure makes use of high-frequency electrical currents to cut, coagulate, or vaporize tissue during surgery. Diathermy pencil replaces traditional scalpels to minimize bleeding and operative time. The electrosurgical pencil is made of a handpiece … Read more

Silk suture is a sterile non-absorbable surgical suture made of organic protein called fibroin. The organic protein, fibroin, is derived from domesticated silkworm species Bombyx mori of the family Bombycidae. The sutures are processed to remove the naturally-occurring sericin waxes and gums. The braided silk suture is coated with silicone or wax. The manufacturing process … Read more
Nylon suture also called polyamide suture, is a sterile synthetic non-absorbable suture, with high tensile strength. It can be microfilament (Ethilon, Dermlon, Daclon) or multifilament (Nuralon). It is easily pliable, smooth, and soft. Nylon gives excellent knot security and are easily removed without tissue resistance. They are also resistant to infection. Nylon is composed of … Read more
Vicryl (polyglactin 910) is the most widely used braided synthetic absorbable suture. The sterile suture was manufactured by Ethicon Inc., a medtech subsidiary of Johnson and Johnson. It is composed of a copolymer made of 90% glycolide and 10% L-lactide. The sutures are coated with a mixture of equal parts of copolymer of glycolide and … Read more
Bone wax suture is a sterile hemostatic agent made of mostly beeswax, isopropyl palmitate, a wax softening agent, and a stabilizing agent such as almond oils or sterilized salicylic acid. It is used to control bleeding of disrupted bone surfaces. The action is not biochemical, rather it acts as an impenetrable mechanical barrier (tamponade) to … Read more
Surgicel, an absorbable hemostat, is a sterile absorbable knitted fabric that is produced through a controlled oxidation of regenerated cellulose. The fabric material is strong, and does not fray when cut and used for suturing. It has a white color with a pale yellow cast and a faint, caramel-like aroma.
