Bright finish and it increases resistance to corrosion but can be distracting to the surgical team because it can reflect

Satin or dull finish instrument are

Less reflective and reduces glare but is prone to staining

Black chromium finish (ebony/ ebonized)

Non reflective and is use for lasers

Handheld instruments have the same design parts including the handles, ratchet shanks, box lock, jaws, or blade and tips

True

Instruments are classified by their function into the following categories

Cutting and dissecting, grasping and holding, clamping and occluding, retracting, viewing, probing, dilating, suturing, and aspirating and suctioning

Instruments that do not fall under the classification are referred to as

Accessory instruments (sponge stick and towel clip)

Instruments with one or more sharp edges are used for

Incision, sharp dissection, or excision of tissue are classified as cutting and dissecting instrument

Scissors

Metzenbaum Scissors

Cutting fine to medium tissue

Grasping and holding instruments

Allis, Babcock, and Kocher

Manipulate tissue to facilitate dissection or suturing, or to reduce and stabilize fractured bone during internal fixation

Thumb forceps do not have

Ratchet

Thumb forceps have

Teeth, serrations, or may be smooth

Thumb force are also for grasping and holding

True

tissue forceps also called

Tissue thumb forceps or pick ups

Bone-holding clamps are

Typically ratcheted and are designed to hold a bone in place for eventually pinning or plating

Instruments for grasping and holding are

Tooth forceps and bonney tissue forceps

Adson Tissue Forceps

Feature fine, delicate tips with teeth and are used for precisely grasping and manipulating soft and delicate tissue.

Smooth or nontoothed forceps are used on delicate tissue

Arson dressing forceps, DeBakey forcep, and general tissue forceps

Clamping and occluding instruments are

Mosquito, crile, and Kelly

Clamping and occluding

Designed to occlude (stop loss of blood) or constrict tissue

When dealing with a clamping and occluding instrument, how should it be passed to the surgeon?
