Absorbable Surgical Catgut (Plain or Chromic) Suture with or without needle
1.1 Chemical composition
Composed of purified connective tissue (mostly collagen) derived from either the serosal layer of beef (bovine) or the submucosal fibrous layer of sheep (ovine) intestines.
1.2 Catgut Structure: Twisted
1.3 Product advantage
Thread tensile strength:WEGO facotry standard is over about 20% of USP and EP Standards
Good attachment strength: Factory standard is over about 20% of USP and EP standards
World first-class level needle: AISI420 OR AISI302 medical steel wire with prominent performances,such as Extremely sharp penetration,Good needle bending strengh,Stable tolerance.
Five times penetration strength chart for one 0.61mm diameter reverse cutting needle:
1.4 Thread colour
WEGO Chromic Catgut is brown,
WEGO Plain Catgut is yellow.
1.5 Suture application.
WEGO Chromic Catgut is applicable for general, soft tissue, approximation and/or ligation, ophthalmic procedures.
WEGO Plain Catgut is applicable for general, soft tissue, approximation and/or ligation, ophthalmic procedures.
2.1Suture Diameter Gauge: European pharmacopeia (EP) standard 1 to 7 (USP 6-0 to #3)
2.2Suture length: ≤3.9m
2.3Needle Length: 3mm-90mm
2.4Needle Type: Taper, Cutting, Taper Cutting, Reverse Cutting, Diamond, PremiumCutting, Blunt Point, Square and SpatulaNeedle Curve: 1/4 circle, 3/8 circle, 1/2 circle, 5/8 circle, Compound Curve, Straight, J Shape.
2.5 Tensile strenght retention days:
WEGO Chromic Catgut: About 14 to 21 days.
WEGO Plain Catgut: About 7 days.
3.1 Surgical Catgut suture meets standards of CFDA and EP and USP for absorbable surgical sutures.
3.2 WEGO Chromic Catgut contains a chromic salt solution to delay absorption, so absorption period is longer than Plain Catgut.
3.3 WEGO Catgut is sterilized by Gamma ray, so sterilization is totally complete.
