Suture, Needles, Staplers, Wound Closure Techniques, & Wound Closure Devices ST230 Concorde Career College
Objectives Define the term suture as a noun and as a verb. List the specifications for suture material and describe the importance of each. Describe the suture selection process.
Objectives List and describe the ideal characteristics for suture material and surgical needles. Identify the types and sizes of suture material, provide examples of each, and describe the type of tissue usage appropriate for each type.
Objectives Identify the types and sizes of surgical needles, provide examples of each, and describe the type of tissue usage appropriate for each type. Describe suture packaging, list the information found on the suture package, and explain its importance.
Objectives Identify types of stapling and ligating devices and provide examples of when each may be utilized.
Objectives Identify types of alternative wound closure materials, tissue adhesives, and tissue repair and replacement materials and provide examples of when each may be utilized.
Definition Suture Noun
Definition Suture Verb (It’s what you do…)
Brief Suture History 3000 BCE - Linen strips and animal sinew (tendon) were used to close wounds with needles made of bone 600 BCE - Cotton, leather, horsehair, and bark fiber from trees was used to close wounds
Brief Suture History Lister (late 1800s) was the first to use a bacteriocide (carbolic acid) on suture Suture manufacture and sterilization started in the early 20th Century First synthetic absorbable suture was produced in the 1960s
Brief Suture History Sinew (wolverine)
Brief Suture History Suture Needle (buffalo bone)
Specifications for Suture Material Must be sterile and sterile technique must be used when handling Uniform tensile strength Uniform size Appropriate diameter for tissue type Provide knot security Cause minimal foreign body tissue reaction
Suture Selection Characteristics of the suture material Age Weight Allergy status General tissue condition Surgical site disease Comorbid condition(s) Surgeon preference Suture availability Cost Mentor influence
Ideal Suture Characteristics Pliable Easy to tie secure knots Tensile strength (will not fray or break) Glide through tissue effortlessly Inert Nonallergenic Inexpensive
Tensile Strength Tensile strength of absorbable and non- absorbable sutures is critical both during and after surgical procedures. Breaking strength and elongation can be measured using either a "straight pull" test or a "knot pull" test.
Types of Suture Material Natural Absorbable Monofilament Synthetic Nonabsorbable Multifilament

Ideal Needle Characteristics Stainless steel (corrosion resistant) Slim without compromising strength Stable in the needle holder Carries suture through tissue with minimal tissue trauma Sharp Sterile Inexpensive
Tie Terms Free-tie – Place a suture (no needle) into the surgeons hands Stick-tie – Suture on a needle (use a needle holder) Tie on a pass – Place the suture (no needle) on an instrument (tonsil/right angle) Ligate – To tie
