what is the difference between mayo-hegar and olsen-hegar
olsen have cutting blades and mayo do not
what is the benefit of lorna edna towel clamps and non-penetrating towel clamps
they do not rip holes in the drapes so it helps to keep sterility
what are these
rochester carmalt forceps
what are these
mosquito forceps
what are these
kelly forceps
what are these and what is the ONLY type of tissue you should use them on
rochester oschner and only for tissue that is going to be removed
what type of suction is this
Yankauer suction tip
what is the difference between LA general pack and an LA laceration pack
less instruments in lac, often have olson hegars, and include sterile towels for drapes
What are metzenbaum scissors used to cut
fine tissue
what are these
doyen intestinal forceps
what are doyen intestinal forceps used for
occlude the lumen of the SI with minimal trauma
T/F: GI stapler staples are reactive in the body
FALSE they are non reactive in the body
what are the advantages of GI staplers
faster if you know how to use them, inert compared to suture, reduce contamination, preserve blood supply, able to use in areas of limited accessibility
what are the disadvantages of GI staplers
expensive, leakage is possible, may be limited if tissue has edema, must be trained to use
what is TA-90
thoracoabdominal stapler
do TA-90 cut?
no, only gives a double row of staples so you must still cut the ends
what type of GI stapler is this
TA-90
what is an ILA and GIA
ILA - intestinal linear stapler
GIA - gastrointestinal anastomosis
what do ILA/GIA do
it is a linear staple that cuts and divides at the same time
what type of stapler is this
ILA/GIA
what is LDS
ligating diving stapler
when is an LDS stapler useful
on mesenteric vessels
what type of GI stapler
LDS
what are benefits and disadvantages of ligating clips
quick ligation of vessels but can slip off easily
when are skin staplers used
for rapid closure of surgical incision
what are the equine emasculators
serra, modified white, reimer, sands, henderson
what type of emasculator is this and how does it work
serra, cuts and crushes at same time
what type of emasculator is this and how does it work
modified white and crush/cut at same time
what type of emasculator is this and how does it work
reimer, crush and separate cutting handle
what type of emasculators is this and how does it work
sands, crush only
what type of emasculators is this and how does it work
henderson and attach to a drill and twist the cord
what are the tools used to castrate ruminants
burdizzo, newberry knife, elastrator bands, emasculator, henderson
what are these, what do they do, and what age animal are they used on
burdizzo, crush only, young animals
what are these, what do they do, and what age animal are they used on
newberry knife, cut scrotum, any age
what are these, what do they do, and what age animal are they used on
elastrator bands, a band that cuts off circulation of testicles, young animals
what is this and what does it do
chain ecraseur
can be used for ovariectomies or to remove other masses with blood supply
what are the components of the arthroscopy equipment
tower, arthroscope, light cable, fluid line, conical obturator, ferris smith rongeurs, currettes, and probe
what is this
arthroscope
what is this
obturator
what is this
cannula
what is this
ferris smith rongeur
what are these
currettes
what is this
probe
what is a DCP
dynamic compression plates
what is a LC-DCP and why is it neat
limited contact dynamic compression plate. has complete strength throughout the entire plate, no weak points
what is this
guarded epiglottic hook knife
what does laser stand for
light amplification by stimulated emission of radiation
when are lasers commonly used in LA/equine
upper respiratory tract surgery
what are the advantages of a laser
decreased bleeding, decreased swelling, decreased pain, kills bacteria as it cuts, use through the endoscope, precise cutting
what are the disadvantages of laser
requires specialized training, equipment is expensive, can result in excessive thermal damage to surrounding tissues
what are all of the surgeries lasers are used for in LA
upper airway sx, uterine cysts, skin tumors, neurectomy, fusing hock joints, hemostasis during laparoscopic surgery
