Metallic
Wire
Suture wire is prepared mainly from
three metals - nontoxic stainless steel, the alloy tantalum and silver.
All
these may be obtained as a single-strand monofilament suture and the first-two
as several strands, either twisted or braided, known as multifilament wire.
Surgical
stainless steel suture wire is used mainly in orthopedics and thoracic surgery.
A stouter wire of sizes 3 to 9 (0 to 7) or 29 SWG would be needed for wiring fragments
of bone together.
Metal Clips
(Ligature)
Ligatures of flattened silver or
tantalum wire are used in neurosurgery and chest surgery for arresting
hemorrhage from small vessels. The insertion forceps and cartridges allow their
use for this purpose at depths with safety.
Metal Clips
(Suture)
These are metal clips having two sharp
points which when the clip is closed, these points grip the edges of the skin
incision and hold them in apposition.
The
original types in use are Michel and Kifa .
Staples
During the past few years there has
been considerable development in the field of suture staples.
These
range from disposable magazines of staples which fit an insertion instrument to
completely disposable units. Examples of two of the latter are Proximate II
(Ethicon) and Appose (Davis and Geck)
