What is this
Weitlaner self retaining retractors
What is this

What is this
Doyen intestinal forcep
What do doyen intetestinal forceps do
Occlude the lumen of the small intestine w/ minimal trauma
What are the advantages of GI staplers
- Faster
- Inert compared to suture
- Reduce contamination
- Preserve blood supply
- Able to be used in areas of limited accessibility
What are the disadvantages of GI Staplers
- Expensive
- Leakage is possible
- May be limited if the tissue is thickened (edema)
- Need trained personnel
Describe TA-90 GI stapler
- A thoracoabdominal stapler
- Does not cut only shoots our a double row of stable
Describe an ILA (intestinal linear stapler) & a GIA (GI anastomosis)
- Linear stapler
- Cuts & divides @ the same time
What is an LDS stapler
- Ligating dividing stapler
- Useful on mesenteric vessels
Elaborate ligating clips
- Quick ligation of vessels
- Can slip off easily
- Need appropriate size for the vessel
Elaborate on skin staples
- Rapid closure of surgical incisions
- Have been associated w/ surgical sit infections
- Appose or evert tissue never invert the tissue
What is this
Serra Emasculator
What is this
Modified White Emasculator
What are the serra & modified white used for
To simultaneously crush & cut
What is this
Reimer Emasculator
What is a reimer used for
To crush & separate cutting w/ the handle
What is this
Sands Emasculator
What are sands used for
Crush only
What is this
Henderson Emasculator
What is the henderson used for
Twist the cord
Delete this
Henderson equine emasculator
What is this
Burdizzo
What is the burdizzo used for
- Crushing only
- Young animals may not get a complete crush
What is this
Newberry knife
Elaborate on the newberry knife
- Cuts the scrotum
- Prevents cutting other structures accidentally
- Perpendicular cuts don’g allow for ventral drainage
What is this
Elastrator bands
Elaborate on elastrator bands
- Typically done by producer
- YOUNG animals only
- Difficult to provide analgesia for several week
What animals are emasculators & henderson used on
More mature animals
What is this & what is it used for
- Chain Ecraseur
- Can be used in ovariectomies or the removal of other masses w/ blood supple

What is this
Ferris smith rongeurs
What is this
Currettes
What is this
Limited contact dynamic compression plates (LC-DCP)
What is this
Locking compression plate
What is this
Guarded epiglottic hook knife
What does LASER stand for
Light Amplification by stimulated emission of Radiation
What are lasers used for in equine URT surgery
- Scar the tissue to make it less flexible
- Incise/excise mucosa or masses
- Can get into tight space of larynx/pharynx
What does lasers have a negative effect on
- Wound healing of a primary closed incision due to there being an area of thermal necrosis
- generates an intense beam of light that can cut, seal, or vaporize tissue; Energized molecules emit a certain wavelength of light
What are the advantages of lasers
- Decreased bleeding
- Decreased swelling
- Decreased pain
- Kills bacteria as it cuts
- Use through the endoscope
- Precise cutting
What are the disadvantage of lasers
- Requires specialized training
- Equipment is expensive
- Can result in excessive thermal damage to surround tisues
When are lasers used in LA surgery
- Upper airway surgeries
- Uterine cysts
- Skin tumors
- Neurectomy
- Fusing Hock Joints (Facilitated ankylosis)
- Hemostasis during laparoscopic surgery
