Week 2 - Instruments Flashcards
Black chromium finish
used on laser surgery instruments; absorbs light and prevents reflection of laser energy into adjacent tissues
EEA
circular or end-to-ed anastomosis stapler
TA
thoracoabdominal stapler; has a right-angled firing section that fits around deep structure for resection and anastomosis
GIA
gastrointestinal anastomosis stapler; used for linear resection, transection, and anastomosis
LDS
ligating-dividing stapler; places a double row containing two staples in each row and severs the tissue between rows when fired
Self-retaining
hold tissue against the walls of the surgical wound by mechanical action
Sizer
trial, reusable replica of an implantable prosthesis
Shears
large cutting instruments used to server bone tissue
Kocher
very common biting clamp; used in general, gyn, and ortho
Heaney
clamp used specifically in gyn sx to grasp the uterine ligaments
Partial occlusion clamp
atraumatic clamp has locking ratchets, tips and shanks; does not close tightly over the tissue
Lahey tenaculum
used on thyroid
Vascular clamps
used to temporarily stop blood flow without damaging the vessel; partial occlusion clamp
Bayonet forceps
angled thumb forceps; typically used in neurosurgical and nasal procedures
Highly polished instruments or Mirror finish
resist staining, highly reflective therefore produce glare under strong lightening
Satin finish
reduces glare prone to staining
Titanium anodizing
method that imparts color and hardness to the surface of titanium, anodizing results in oxidation
Gold dip or black finish
highly resistant to scratching, pitting, and dulling; the working tip or edge of the instrument bas tungsten carbide inserts, inserts prevent needle from slipping/rotating
Kerrison
fine tipped rongeurs; long handled delicate, often used for spinal surgery
Alloy
combination of several different kinds of metals
Box lock
hinge point of many surgical instruments
c/hisel
orthopedic instrument used to slice bone; one side is straight and other is beveled
Curettage
removal of tissue by scraping with a surgical curette
Dilator
graduated smooth instrument that is used to increase the diameter of an anatomical opening in tissue
Elevator
straight instrument with curved sharp or dull tip used to separate tissue layers
Gouge
V-shaped bone chisel
Hemostat
surgical clamp most often used to occlude a blood vessel
Rongeur
hinged instrument with sharp, cup-shaped tips that used to extract pieces of bone or other connective tissue
Serosa
delicate outer layer of tissue of most organs
Shank
area of a surgical instrument between the box lock and the finger ring
Single-action rongeur
heavy cutting instrument that has one hinge
Tenaculum
grasping instrument with sharp pointed tips, generally used to manipulate or grasp tissue such as thyroid or cervix
Retracting/exposing
hold back the edges of a wound to permit visualization of the operative site
Suction
vary in length, curvature, and lumen diameter and are selected according to type of surgery and amount and depth of fluid to be suctioned
Toxic anterior segment syndrome (TASS)
acute anterior segment that can lead to impaired vision; associated with inadequate cleaning ophthalmic instruments following cataract and anterior segment sx
Critical device
devices that penetrate mm and enter normally sterile areas of the body
Semicritical device
contact intact mm and must be high-level disinfected (at a minimum)
Noncritical devices
contact intact skin and require low level disinfection or cleaning with soap and water
Adson
Tissue thumb forceps
Key
elevator; used in neurological procedures for lifting soft tissue and periosteum and lift bone
O’Sullivan-O’Connor
self retaining retractors; frame and blades of various sizes
Balfour
self retaining retractor; used for abdominal procedures
