PGA (Polyglycolic acid)
DESCRIPTION
-
Structure: braided multifilament
-
Color: violet, undyed
-
Chemical composition: polyglycolic acid
-
Coating: polycaprolactone + calcium stearate
-
Absorption type: hydrolysis
-
Sterilization: ethylene oxide
-
Absorption time: 60 - 90 days
sterile absorbable synthetic, multifilament suture composed of glycolic acid. The sutures are braided and coated with a blend of polycaprolate, copolymer of caprolactone and glycolide and Calcium Stearate
CHARACTERISTICS
Absorbable suture is widely used in surgery, because it can be absorbed, so there is no need to remove the suture and avoid secondary pain. PGA absorbable suture has the following obvious characteristics:
-
High initial tensile strength
-
Excellent knotting ability
-
Outstanding holding power through the critical would periode
-
Reliable absorbability
-
Easy to handle
-
Holds knot securely
-
Smooth surface, slides smoothly through the tissue
INDICATIONS
PGA absorbable Sutures are indicated for use in ge-neral surgery. It is suitable for the coating of soft tissue and for ligation and also for use in ophthalmic procedures but not for use in cardiovascular tissue and neural tissue. Applicable also in gynecology, pediatric surgery, gastrointestinal surgery and also in odontology. The PGA surgical sutures are absorbable and it is not suitable for the parts that need suture support for too long time.
PROPERTIES
PGA absorbable Sutures have a high initial tensile strength, which is retained for up to 28 days:
-
70% of their tensilestrength by the 2nd week;
-
50% by the 3rd week.
After which absorption byhydrolysis begins, where the polymer degrades to glycolic acid, which is absorbedtotally by the body between 60-90 days.
