Absorbable Non-Absorbable General Applications Topical Adhesives Needles

3 Basic Terms Associated With Sutures
Primary Suture Manufacturers: Syneture (Covidien) Ethicon Specialty Suture Manufactures: Gore Tevdek

4 Types of Suture Material
Absorbable - Suture material is absorbed over time by the body. Non-Absorbable - Suture material is permanent - not absorbed by the body.

5 Basic Terms Associated With Sutures
Absorption Profile - The number of weeks or days it takes the body to absorb suture. Tensile Strength - The amount of force necessary to break a suture. It is measured in days with absorbable sutures. Hydrolysis - Absorption process that uses the body’s water - Synthetic sutures are absorbed by hydrolysis.

6 Basic Terms Associated With Sutures
Enzymatic Process - Suture that is absorbed by the body’s enzymes - Gut suture products are absorbed in this manner Degrade - A non-absorbable suture’s tendency to crumble and fall apart over time. The material is not absorbed, but it does not stay intact - Silk, Nylon Mechanical Trauma Trauma to the suture by mechanical instruments can result in suture failure. Compression of sutures between a needle holder with teeth can produce morphologic changes in sutures that can result in a marked reduction in suture breaking strength

7 Basic Terms Associated With Sutures
Braided - A suture strand that is woven or braided with numerous filaments. Monofilament - Suture strand is composed of a single strand or filament. D-Tach/ Pop-Off - Suture/needle combination that is designed so that the needle detaches from the suture strand when appropriate force is exerted.

8 Basic Terms Associated With Sutures
Running Closure - AKA “Continuous Closure” - Incision closed with repeated passes of one single suture. Interrupted Closure - Incision is closed with numerous sutures each tied separately. Double Armed - Needle on both ends of suture Taper – Refers to a taper point needle generally used inside the body Cutter - Refers to a cutting needle used generally to close skin

9 Review of Primary Tissue Layers
The primary layers which will determine the type of suture, needle and suturing technique used are: Skin Subcutaneous fat Anterior Fascia Muscle Posterior Fascia Peritoneum

10 Suture and Tissue Reactivity
Although sutures are necessary to provide wound support so healing will occur, they may also cause a tissue reaction at the wound site. Tissue reactivity is the patients response to the physiological properties of the suture (what the suture is made from ). It can also be referred to as a foreign body response.

11 Suture Function and Wound Healing
Sutures function to hold wounds together until wound healing takes place. Fourteen to twenty-one days is often regarded as the critical wound healing period. It is during this time that the sutures provide strength to the closed wound, allowing the tissue to heal with minimal scarring.

12 Monofilament /Multifilament
Suture Structure Monofilament /Multifilament

13 Suture Sizing - USP (United States Pharmacopoeia: - Diameters and strengths)
Human hair Chest Skin Micro / Ophthalmic Abdominal closure CABG *Suture Sizes range from a size 7 being the largest to a size 11-0 being the smallest (Note the typical application for each size by reviewing the chart on this slide) More 0’s = smaller size

14 Suture Products Absorbable Products: Non-absorbable Products
Braided Synthetic Monofilament Synthetic Organic Absorbables Non-absorbable Products Organic Nonabsorbables

15 Suture Products Absorbable Sutures
Braided Synthetic Absorbables (BSA) Polysorb - Syneture 92.5% Polyglycolic 7.5% Polylactic Acid Tensile Strength for 3 weeks Absorbed in 56 to 70 days Vicryl - Ethicon 90% Polyglycolic 10% Polylactic Acid Tensile strength for 3 weeks

16 Suture Products Absorbable Sutures
Braided Synthetic Absorbable (BSA) Advantages: Tremendous strength Resistance to breakage due to multifilament construction Relatively little memory Easy to handle and tie Tremendous variety of needle/suture combinations.

17 Suture Products Absorbable Sutures
BSA Disadvantages: Tends to be rougher on tissue as suture pulled through. Braids have potential to harbor infection due to numerous interstices. Can be a medium for stone formation in GYN and GU procedures involving the bladder and surrounding structures.

18 Suture Products Absorbable Sutures
BSA General Applications: General Surgery Mid line fascia closure Subcutaneous layer closure Subcuticular skin closure Bowel anastomosis Other general tissue closures

19 Suture Products Absorbable Sutures

21 Suture Products Absorbable Sutures

22 Suture Products Absorbable Sutures
Long absorption profile Monofilament Synthetic Absorbable Maxon - Syneture PDS - Ethicon Both sutures provide tensile strength for 6 weeks and are absorbed by the body in 180 days. Maxon maintains slightly higher tensile strength during the first two weeks in vivo Some surgeons might notice slight handling differences between the two sutures

23 Suture Products Absorbable Sutures
Long absorption MSA applications: Midline incision closures Looped products are increasing in popularity Bowel anastomosis Any application where extended approximation (three to six weeks) of tissue is needed.

24 Suture Products Absorbable Sutures
MSA Advantages: Smooth flow through tissue Resistance to bacteria, infection and stone formation due to monofilament construction Latest technology from suture manufacturers Variety of absorption rates Best replacement for gut products

25 Suture Products Absorbable Sutures
MSA Disadvantages: Out of package memory Stiff and slightly more difficult to work with Knots require additional throws

28 Suture Products Absorbable Sutures
Gut Products Generally fast, unpredictable absorption rates Decreasing in popularity Banned in Europe and Japan

29 Suture Products Absorbable Sutures
Things to remember about Absorbable Suture Products - Means of absorption Synthetic absorbable sutures are absorbed by hydrolysis (the body’s water) and are generally deemed to have predictable strength and absorption profiles Organic absorbable sutures (gut products) are absorbed by the body’s enzymes and are generally thought to be more unpredictable in strength and absorption profile than synthetic absorbables.

46 Surgical Needles

47 Needles must possess the following characteristics:
The needle must be sharp enough to penetrate tissue with minimal resistance. The needle must carry the suture material through tissue with minimal trauma. The needle must be rigid enough to resist bending, yet flexible enough to bend before breaking.

48 Every surgical needle has three basic parts
The swage is the site of attachment of the suture to the needle. The body of the needle is the portion that is grasped by a needle holder. The point of the needle extends from the tip of the needle to the maximum cross section of the body.

49 Needle Shapes

50 Needle Points Specific points are designed and produced to the required degree of sharpness to smoothly penetrate the types of tissue to be sutured. The point is from the extreme tip of the needle to the maximum cross section of the body.

51 Surgical Needles Types of Surgical Needles:
Taper Needles - Vast majority of needles are this type General Tissue Closure Midline, Sub Q, Peritoneum Vascular closures and anastomosis Bowel closure and anastomosis

52 Surgical Needles Types of Surgical Needles (Cont.)
Cutting Needles - Needles with a triangular cutting configuration. Used for penetrating tough, fiberous tissue. Sub Cuticular skin closure Percutaneous skin closure Skin sutures for securing drains Various orthopedic tissue applications Ligaments etc.

53 Surgical Needles Types of Surgical Needles (Cont.)
Taper cutting needles - Point of needle has a cutting tip. Body of needle quickly tapers. Used in places where taper needles are desired, but may not be quite sharp enough. Vascular procedures where vessels are heavily plaqued.

54 Surgical Needles Types of Surgical Needles (Cont.) Spatula Needles -
Used primarily in ophthalmic surgery Deflects or pushes aside tissue as the needle passes Come in a variety of configurations. Blunt Needles - Needles have a blunt tip Used primarily on delicate or friable tissue (Liver) or on patients with high risk blood diseases.

55 Surgical Needles Types of Surgical Needles (cont’d)
X-Cutting Dermax needles (proprietary to Syneture) Features a fourth cutting edge that allows four dimensional control: horizontal (left/ right), and vertical (up/ down) Unique double-point profile geometry for easier puncturing and needle embodying into the tissue. Used primarily in cosmetic procedures, & percutaneous skin closures.
