There was no statistically significant difference in recurrence rates on fixation of mesh with tackers.
There are several studies showing non-fixation as a viable option without increased risk of recurrence, but also has the advantages of shorter operative time, less chronic groin pain and overall improved quality of life when compared to tacker fixation.
We also used titanium tackers to fix the mesh approximately 1 cm apart.
In six patients we used tackers with transfacial fixation sutures
said this about North American sales, "In sewing, our strongest products have been electronic double-needle tackers.
We believe our optimism is supported by a Brother executive who told Bobbin magazine that their strongest sewing product in North America has been electronic double needle tackers machines that integrate Tice Technology(R) and know how.
But we'll focus on the three types generally used in home-related projects: the hand trigger gun, the electric gun and the hammer tacker.
CEO Bill Tice said that the increase is based on sales of Brother's first two classes of machines with Tice Technology(R) and know-how; the electronic double-needle tacker and a multi-head embroidery machine.
