Instrument Identification Flashcards
Gelpis Retractors
Used for muscle & joint retraction.
- self retaining
- single point at each end
- have a ratchet
Metzenbaum Scissors
Used for more delicate surgeries.
- finer & longer handles
- ‘dissecting’ scissors
- straight or curved
Wire/pin Twisters
Enables easy twisting under tension.
- shear action cutter
- jaws have fenestration for extra grip
- jaws lock onto wire/pin
Scalpel Handle Size 4
Used for large animal - divide tissue with minimal trauma.
- usual blades for small animal (10, 11, 12, 15).
- size 3 = small animal, 4 = large animal
Mayo Scissors
Dissecting scissors.
- shorter in length and wider than metzenbaum.
- straight or curved
- most commonly used
Cross Action Towel Clip
Used to attach drape to patient or instrument to operating site.
- less traumatic to tissue than backhaus
- spring like clip
- cross shape
Mcphails Needle Holder
- traditionally have copper in the tips (can get with T.Carbide as stronger)
- handles have a spring ratchet
- squeeze handle to release needle
Olsen-Hegar Needle Holders
- cutting edge
- ratchet
- very popular
Sherman Plate
Internal fixation device
- identified by rounded ends and tank track like.
- used to immobilise fracture site
Venables Plate
Internal fracture repair
- circular holes for screws
Mayo-Hegar Needle Holders
Resemble long-handled artery forceps
- have a ratchet
- no cutting edge
Allis Tissue Forceps
Designed to grasp tissue with minimal trauma.
- more traumatic than babcocks
- not to be used on viscera (too delicate)
Bone Cutters
Designed to cut larger pieces of bone
Backhaus Towel Clip
Used to attach drape to patient to instrument to operating site.
- pointed end
- ratchet
- ringed handles
- more traumatic to tissue than cross action.
Chisel
Used to cut/shave bone/cartilage.
- chisel bevelled on one side whereas osteome bevelled on both sides.
Rat Tooth Forceps
Dissecting forceps used to hold tissue.
- held like a pencil
- toothed ends used for denser tissue
- plain ends used for delicate tissue
Cortical Screw
Used in cortical bone (harder dense layer)
- threads are closer
- shallower
- Asif screw identified by hexagonal head.
Cancellous Screw
Used in cancellous bone (soft, spongy)
- threads are further apart
- deeper
- ASIF screw identified by hexagonal head.
Gillies Needle Holders
Designed for holding suture needles during suturing and knot tying.
- scissor action
- no ratchet
- needle has to be held in place by gripping
Senn Retractor
Used to primarily retract surface tissue
- double ended retractor
- often used in small bone/joint procedures or thyroidectomies.
Olsen-Hegar Needle Holders
- Needle holders
- cutting edge
- ratchet
Ronguers
Used to cut out or nibble small pieces of dense tissue such as bone/cartilidge.
Babcock Tissue Forceps
Used to grasp tissue with minimal trauma.
- less traumatic than allis tissue forceps
- Should not be used on viscera
Periosteal Elevator
Used to lift periosteum and soft tissue of bone.
- tip must be protected and kept sharp
Plate Blenders
Used to reshape plates around bone in order to repair fractures.
