General surgery instruments come in several different classifications, including flexible and rigid endoscopes, powered equipment and hand held instruments, such as forceps, needle holders and scissors, according to Teleflex. Forceps offer the most commonly used design form of surgical instruments
Hemostatic forceps control blood flow from the vessels, and vary in length, curvature and serration, Teleflex states. As with hemostatic forceps, soft tissue forceps have ring handles and box locks, although they also feature narrow teeth to create a more delicate handle. They are used pull back and hold soft tissue for lengthy periods of time. There are also bone holding forceps, dressing and splinter forceps, and towel forceps.
Scissors are a soft-tissue instrument, and fall into several subtypes, including operating scissors, suture and wire cutting, dissecting and bandage, notes Teleflex. Curved scissors are optimum for dissection, as they provide a better sight line, whereas straight scissors are useful for sutures, vessels and nerves. Larger scissors are helpful in deep cavities and smaller scissors can be utilized at the surface.
Available in a variety of shapes and designs, needle holders clasp needles that are attached to sutures, Teleflex describes. They have a smaller opening than hemostats, and are shorter and thicker. Examples include Crile-wood, Mayo-Hegar and Webster. Like scissors, the shorter needle holders are useful for surface work, whereas the longer holders are better for deeper cavities.
