Sterile instruments Flashcards
What are instruments typically made out of?
titanium or steel
What are the 3 finishes of stainless steel?
- anodized plating
- ebony plating
- mirror plating
What are characteristics of anodized plating?
- satin finish
- Dull, glare-proof quality
- prone to corrosion
What is ebony plating?
- black finish
2. eliminates glare and prevents laser beam reflection
What is mirror plating?
- shiny finish
2. can impede visibility and create a distraction to the user
What is the term used for titanium that means it does not interact with other substances
inert
What is titanium compared to stainless steel?
lighter, stronger, and harder
What kind of instruments are made out of titanium?
generally microsurgical
Is titanium magnetic or nonmagnetic?
nonmagnetic
What kind of finish does titanium have?
blue, anodized finish to reduce glare
What can be applied to any metal surface?
plating
What can plate application do?
chip, peel, rupture, and corrosion
What is used to signify plating?
gold color
What are the 4 classifications of instruments?
- cutters
- clamps
- retractors
- other
What are types of cutters?
- scalpel blades
- scissors
- rongeurs
- osteotomes
- adenotomes
- dermatomes
What are types of clamps?
- hemostats
2. graspers/holders
What are the 4 types of graspers/holders?
- kosher clamp
- allis clamp - little teeth
- adson forceps - fat normal looking
- Babcock forceps - straight with hole
What are 2 categories of retractors?
- hand held
2. self-retaining
What are the 4 types of instruments in the OTHER category?
- probes
- suction tips
- smoke evacuation devices
- mallets
What are the 4 parts of a needle holder from left to right?
- jaws
- joint
- shank
- ratchet
- ring
What is the most common joint type?
box lock
What are the 3 different types of joints?
- aseptic - semi box
- box lock
- screw
What is aseptic joint?
2 halves that compromise the instrument can be separated with dislocation of this joint type
What is box joint?
most common joint type. One arm is passed through a slot in the other arm and the two halves are secured with a pin or rivet
What is a screw joint?
the two halves that comprise the instrument are aligned and secured with a screw that must be checked before surgery so that it is not lost in the patient
Instrument set assembly requires what six basic considerations?
- type of surgery
- patient population
- needs of the specialty surgery providers
- tray weight
- sterilization method
- weight of the instruments
What is special about the tips on laparoscopic instrumentation?
- the tips are key to the identification of the instrument
Insulated laparoscopic instruments are prone to what?
tears and cracks that can result in patient burns
What must be checked on laparoscopic instrumentation?
the insulation integrity must be checked during use and throughout instrument processing
How are endoscopes classified?
according to their bending ability
What are the 3 types of endoscopes?
- rigid
- semi-rigid
- flexible
What do operative scopes have?
a channel that allows for the use of instrumentation
How do operative scopes differ from non-operative or diagnostic scopes?
do not have a channel
What are similar to laparoscopic instruments?
the instruments inserted into the robotic arms
How does a surgeon operate robotic instrumentation?
surgeon operates the instruments, scope, and camera from the console
What has the camera monitor and light source for robotic instrumentation?
a video cart
What are 3 key considerations for powered instruments?
- Power sources – Power cords and the power unit or battery are specific to the hand piece. 2. Powered instruments are not immersible.
- The correct powered instrument is chosen for the intended use.
How should instruments be handled?
• Instruments are organized on the sterile field to protect scrub personnel and prevent instrument damage.
• The right instrument is chosen for the intended purpose to prevent patient injury or instrument damage.
• Sterile water is used for point-of-use cleaning.
• The contaminated instruments are transported in a closed container as soon as possible after completion of the
procedure.
When Is instrument inspection conducted?
- at the point of use
2. in the sterile processing department.
What is scheduled to ensure that instruments are in proper working order?
preventative maintenance is scheduled and performed
What may require lubrication during preventative maintenance and as part of sterile processing?
instruments
An understanding of surgical instrumentation that includes the item’s name and purpose are critical elements that what?
- Promote an understanding of a common language among all members of the surgical team
- Inform the count process
- Can reduce time spent in the OR/procedure room
