suture info Flashcards
(23 cards)
- 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
what part of the needle should you grab with the needle driver
body
skin closure on face..
monofilament non-absorbale (nylon, proline)
subQ skin closures elsewhere
monofilament absorbable (monocryl, biosyn)
trauma and mobile areas
large diameter, monofilament non-absorbable
suture size for small vessels or delicate facial plastic surgery
6-0 and 7-0
suture suze for hella tension, closure of muscle layers or repair of bowel
2-0 and 3-0
suture size for closing fascia layer in abdomen, joint capsule in knee, hip, deep layer of back surgery
1 or 0 (0 is smaller in this case)
suture size for tendons or high tension in orthopedics
2 or 5 (2 is smaller)
