Trocars,
Tunnelers
and Pins
These
solid instruments are made from stainless steels, aluminum
and nitinol wire or bar, and range in size from 0.008” (200
microns) to over 0.500” (12.7 mm) in diameter. They often
feature a cutting point or blade on the distal end of many
configurations, and a variety of designs such as a handle,
finger button, barb, or threaded fitting on the back or proximal
end. DSA’s principals achieve the sharpest cutting edges and
points on these devices with a tight focus on the surface
finish of the body.
Products
in this class of instrument include wound drainage trocars,
trocar / cannula sets, Guide Pins, Obdurators, K-Wires, Steinmann
Pins, tunnelers and introducers. Custom laparoscopic trocars
and high volume production of wound drainage products are
a specialty.
All metal
parts are electropolished to remove burrs, reduce particulate
lodgment and provide a uniform, polished appearance. 100%
visual inspection of finished goods, statistical process control
and complete traceability of materials by heat number are
maintained for all products.
