Chromium increases resistance to

corrosion

Blades #20-#25 fit which # handle?

#4 handle

Blades #10, #11, #12, and #15 fit which # handles?

#3, #7 and #9 handles

The suffix -tome refers to an instrument for

cutting

Grooves located on the jaws of surgical instruments that are either longitudinal, cross-hatched, or horizontal are called

serrations or teeth

This feature of a clamping/occluding surgical instrument controls the opposing jaws of the instrument

The box lock

Instruments designed for the exposure of the operative site are called

Retractors

Instruments used to gradually increase the diameter of an orifice to allow for introduction of larger instrumentation or to open a stricture are called

Dilators

An instrument with a sharp point and cutting edges that allow for penetration of a body cavity for the drainage of fluid or the introduction of an endoscope is called a

Trocar

This type of instrumentation is typically made of titanium because it is stronger yet lighter in weight.

Microinstrumentation

Name the 3 phases of handling of instruments referred to as the instrument cycle are

1. Preoperative
2. Intraoperative
3. Postoperative

What is used to ensure that all necessary instruments from each category are included in the set being used?

A count sheet

Used for diagnosis, biopsy, visualization and/or repair of a structure with a body cavity or the interior of a hollow organ.

An endoscope

Instruments used in the OR that are run by compressed air or nitrogen, electricity or batteries are called

Power tools

The blade of a craniotome cuts through the cranium with a rotary motion and the delicate tissue underneath is protected by a

Dural guard located at the foot of the instrument

The ability of the optical system to filter out adjacent images and to clarify detail is called the

Resolving power

Uses liquid nitrogen, Freon, or carbon Dioxide gas to deliver extreme cold through insulated probes

Cryotherapy units

Carbon Dioxide gas is infused into the abdominal cavity through a

Verress insufflation needle

Name the 5 components of a suction system

1. Vacuum source
2. Vacuum source tubing
3. Collection unit
4. Tubing
5. Suction tip

A device that is powered by nitrogen, battery or electricity that is used to debride a traumatic or infected wound is called a(n)

Irrigation /Aspiration (IA) device

A device that produces very small electric currents that, when applied to tissue, help to identify and preserve essential nerves is called a

Nerve Stimulator

This device restricts blood flow to the surgical site for some procedures

A Tourniquet

List the 2 main purposes that the tourniquet serves

1. The amount of blood lost by the patient is minimized
2. Visualization of the surg.ical site for the sterile team members is improved.

These devices are applied to the patient's leg to prevent venous stasis in the operating room

Sequential compression device

Disposable drapes that have reinforced layers of material surrounding the opening of the drape are called

Fenestration drapes

This drape is made of a thin, clear, plastic material that has an adhesive backing applied to the patient's skin that may be impregnated with an antimicrobial iodine agent

Incise or Ioban drape

This small drape of clear plastic with openings surrounded by an adhesive backing is commonly used to drape eyes

Aperture (fenestrated) drapes

This drape is used to create an opening for a surgical site or to drape and extremity

Nonfenestrated "U" or split sheet

These drapes are designed as stretchable tubes to cover extremities. One end is closed and they come in both impervious and non-impervious types.

Stockinettes

Neurological sponges are referred to as

Cottonoids or patties

Small rolls of cotton tape that come in packages of 5 and are used to aid the surgeon in blunt dissection of tissues are called

Kitners

This dressing is used to cover a small incision from which drainage is expected to be minimal

One-layer dressings

Skin closure tapes used to maintain approximation of the wound edges and by be used alone or with another type of dressings

Steri strips

A type of liquid chemical one-layer dressing

Collodion

A three-layer dressing used to create an airtight and watertight seal

Occlusive dressing

The most frequently used option for securing dressings

Tape

A type of three-layer dressing to which additional material is added to the intermediate layer or one that is tightly secured to cause compression of the surgical wound

Pressure dressing

A three-layer dressing to which additional material is added to the intermediate layer

A bulky dressing

Casts and splints are examples of what type of dressing?

Rigid dressing

Typically used to drain urine, but may also be use to provide irrigation fluid within a duct

Urinary catheter

Used to measure urinary output over an extended period or to provide bladder decompression

Foley catheter

The Pezzer and the Malecot are examples of what type of catheter?

Suprapubic catheter

This catheter is used to decompress the kidney, identify and protect the ureters with the assistance of a cystoscope

Ureteral catheters

This catheter is used to infuse fluids, obtain a diagnosis, monitor body functions and remove thrombi

Intravascular Catheters

Tubes used to aspirate air and fluids from the GI tract

Gastrointestinal tubes

Tubes used to maintain patency of the upper respiratory tract

Airway tubes

A "stab" wound is used to accommodate what type of tube?

A chest tube

A T-tube is used to drain

bile from the Common Bile Duct (CBT)

Fluids are allowed to move out of the wound into dressing by capillary action with what type of drain?

The penrose drain

These types of drains use negative pressure while connected to a collection device. Examples are Hemovac, Jackson-Pratt, or Stryker.

Active drains

These types of drains allow a pathway for fluids or air to move from an area of high pressure to low pressure. Examples are Penrose, Cigarette, T-tube, Gastrostomy, Cystostomy, or Nephrostomy.

Passive drains

Used to inject medications into tissues or intravenous tubing.

Hypodermic needles

Large percutaneous needles use to obtain tissue samples from within the body.

Biopsy needles

Used to irrigate wounds, aspirate fluids, or inject medications

Syringes

This locks the needle onto the syringe tip with a twisting motion

Luer-Lok tip

The standard irrigating bulb/barrel syringes for most procedures is called the

Asepto syringe

During a lengthy procedure of duration that is greater than 1 hour what is recommended?

Deflate the tourniquet periodically for 10 minutes then reinflate

Radiopaque sponges used for procedures requiring smaller incisions

Raytec sponges

Cotton-filled gauzes with a string attached that come in packages of 5

Tonsil sponges
