STERILACTIN®
Sterilactin® is
a polyglactine based braided synthetic absorbable
suture, coated with Polyglycolide-co-L-lactida
(Glacomer 37) and calcium stearate
After some years of
the invention of the 100% pure PGA by D&G research
teams, soem legal litigations over the patents
of the PGA based sutures caused some companies to change the formula by reducing the PURE PGA content from 100% down to 90% and this has caused the bird of POLYGLACTINE (PGLA) based absorbable sutures. Although this new suture did not add any significant difference to the already exiting pure PGA based sutures, through of the originators of this molecule. Today available scientific literature clearly shows us that, in the succes of operation the personal dexterity of the surgeon and his knowledge level about the wound site's physiological situtaion plays a more important role than the choice of material. On the otherhand, pure PGA or PGLA they both get absorbed more or less at around 60 to 90 days; they are available as both braided or monofilament in the world merkets; and they both keep approximately 50% of their initial tensile strength at the and of the 21 days. So based on the scientifically available data it is almost impossible to claim that one molecule is significantly different than the other one. So as SSM corporation after years of succesful use of our 100% PURE PGA based suture, this year we have decided to launch PGLA to enrich ou line of braided synthetic absorbable suture for the customers who using only PLGA.
The absorbable suture material STERILACTIN® is synthenic absorbable Polyglactin material consisting of polyglycolide-co-L-Lactide- (Glacomer 91).
STERILACTIN® sutures are coated wityh Polyglycolide-co-L-lactide (Glacomer 37) and calcium stearate for easier handling, better sliding through the tissue and to protect the suture from early hydrolysisas well as improving the retention of tensile strength.
STERILACTIN® suture is colored using D&C Violet No # 2 (Color index number: 60725).
The diameter of STERILACTIN® strands varies from 0.040 mm 0.899 mm. The length of STERILACTIN® strands varies from 45 cm to 180 cm. The length of needles varies from 11 mm to 90 mm. The shape of needles varies from 3/8 to 1/2 circle.
STERILACTIN® suture elicits a minimal acute inflammatory rection in tissue and ingrowth of fibrous connective tissue. Progressive loss of tensile strength and eventual absorption of STERILACTIN® sterile, synthetic, absorbable sutures occurs by means of hdrolysis, where the copolymer degrades to its monomers (glycolic and lactic acids), which are subsequently absorbed and metabolized in the body. Absorption begins as a loss of tensile strength followed by a loss of mass. The material holds approximately 65% of its tensile strength by the end of two weeks and about 50% after three weeks. The absorption is completed in approximately from 60 to 90 days. |
