Transcript of "Sutures material"

  1. 1. SUTURES MATERIAL
  2. 2. SUTURING • SUTURES: – used for putting the tissue back in place – usually use silk (non-resorbable) • requires post-op visit to remove – occasionally plain or chromic ―gut‖ (resorbable) when close to student break time • both made from sheep/cow , not ―cat‖ – Others (Dexon, nylon etc.) for special use
  3. 3. Different Types of Sutures • There are different kinds of sutures. • Most sutures are actually done the same way but made out of different things. • First we have to know there are two different master types, absorbable and nonabsorbable. • Absorbable of course can be absorbed by the body naturally, and non... can't. .
  4. 4. What are the types of resorbable sutures? Nonresorbable sutures? Resorbable • Plain gut • Chromic gut • Synthetic • Vicryl • Dexon Non resorbable • Silk • Synthetic • Nylon • Mersilene • Prolene
  5. 5. Synthetic suture materials • Absorbable – Polyglycolic Acid (Dexon) – Polyglactin (Vicryl) – Polydioxone (PDS) – Polyglyconate (Maxon) • Non-Absorbable – Polyamide (Nylon) – Polyester (Dacron) – Polypropylene (Prolene)
  6. 6. Natural suture materials • Absorbable – Catgut - Plain or chromic • Non-Absorbable – Silk – Linen – Stainless Steel Wire
  7. 7. Catgut • Made from the submucosa of sheep gastrointestinal tract • Broken down within about a week • Chromic acid delays hydrolysis • Even so it is destroyed before many wounds have healed
  8. 8. Silk • Strong and handles well but induces strong tissue reaction • Capillarity encourages infection causing suture sinuses and abscesses
  9. 9. Vicryl • Tensile strength – 65% @ 14 days – 40% @ 21 days – 10% @ 35 days • Absorption complete by 70 days
  10. 10. Polydioxone • Tensile strength – 70% @ 14 days – 50% @ 28 days – 14% @ 56 days • Absorption complete by 180 days
  11. 11. Absorbable suture are broken down by either: • Proteolysis (e.g. Catgut) • Hydrolysis (e.g. Vicryl, Dexon)
  12. 12. SUTURING • Info on front of package explains – shape of needle – Thickness of suture material (higher no. thinner suture – whether needle is ―cutting‖ or ―tapered‖
  13. 13. Ethicon Sutures
  14. 14. Polyglycolic acid PCA Chromic catgut CC
  15. 15. Polypropylene Silk braided (SK)
  16. 16. • Thread length 45cm,,60cm ,75cm,100cm,125cm,150cm • Thread diameter 8/0, 7/0,6/0, 5/0, 4/0, 3/0,2/0,1/0,1, 2, 3
  17. 17. • Needle length 6mm, 8mm, 12mm, 18mm, 22mm, 30mm, 35mm, 40mm, 50mm • Needle curvature Straight, 1/2 circle, 1/2 circle (double), 1/4 circle, 1/4 circle (double) 3/8 circle, 3/8 circle (double), 5/8 circle, loop round
  18. 18. • Cross section Round bodied, round bodied (heavy), curved cutting, curved cutting(heavy) Reverse cutting, reverse cutting (heavy), tapercut, micro-point spatula curved
  19. 19. needle identification
  20. 20. Needle shape
  21. 21. Suture materials
  22. 22. Rapid Absorbable Suture
  23. 23. DemeTech's Rapid Absorbable Sutures • DemeTech's Rapid Absorbable suture is a, synthetic, absorbable sterile, surgical suture composed of copolymers made from 90% glycolide and 10% L-lactide. • . The absorption time for Rapid Absorbable is 42 to 56 days.DemeTech's Rapid Absorbable sutures are available violet and colorless.
  24. 24. • · DemeTech's Rapid Absorbable sutures give the best characteristics of both natural and synthetic sutures, allowing for the low infection rate of a synthetic suture, while providing the quick absorption and high tensile strength of collagen sutures (catguts).

  26. 26. What are the principles of suturing technique? • The suture should be grasped with the needle holder three-fourths of the distance from the tip. • The needle should be perpendicular when it enters the tissue. • The needle should be passed through the tissue to coincide with the shape of the needle. • Sutures should be placed at an equal distance from the wound margin (2—3 mm) and at equal depths.
  27. 27. What are the principles of suturing technique? • Sutures should be placed from mobile tissue to fixed tissue. • Sutures should be placed from thin tissue to thick tissue. • Sutures should not be overtightened. • Tissues should not be closed under tension. • Sutures should be 2—3 mm apart. • The suture knot should be on the side of the wound.
  28. 28. When should intraoral sutures be removed? • In uncomplicated cases, sutures generally may be removed 5—7 days after placement.
