 Most modern surgical instruments are made of | Stainless Steel |
| 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 |
