suture info Flashcards
- better knot security & less memory (less likely to kink or curl)
braided suture
- less resistance through tissue
- ties down easily but crushing or crimping may weaken
monofilament
breaks down through enzymatic process
ex: catgut
natural absorable sutures
- breaks down via hydrolysis
- ex: dexon, vicryl, PDS, Maxon
synthetic absorbable sutures
- ## reduces risk of FB reaction
Absorbable sutures
- better holding power
- more give with significant edema/swelling
- less reactive in short term so better scar
permanent suture
Uses: skin closure, subQ tissue, sometimes for ophthalmic surgery, plastic or reconstructive surgery
Triangular point with cutting edge on the inner curvature and precision-honed for added sharpness
Precision Conventional Cutting– triangle with line in middle sign
- Triangular point with cutting edge on the outer curvature
- Skin closure, ligamentous or fibrous tissues
reverse cutting– empty upside down triangle
- Triangular point with cutting edge on the outer curvature and precisioned for added sharpness
- plastics in delicate procedures
precision reverse cutting
- Round shaft, straight or curved, taper point with no cutting edge
- soft tissue, GI, vascular
taper point– shaded circle with another circle around it
- four cutting edges with taper shaft for penetration through tough tissue
- taper cutting– circle surrounding upside triangle with line in middle
- Spatula needle with the cutting edge on the inner or outer curvature
- optho and microsurgery
spatula– upside down trapezoid with upside down Y inside
a filled in upright triangle means..
cutting edge
a filled in circle means
tapered point– used more under the skin or for first pass above the skin
Polyamide (nylon)
polyester (dacron)
polypropelene (prolene)
non absorbale synthetic suture
