DeBakey

Tissue forcep

delicate, minimize trauma to tissues
groove between teeth, and smaller teeth
GI or bladder surgery

Hemostatic forceps are ________

Crushing

- clamp blood vessels and tissue pedicles

Halsted mosquito hemostatic forceps

straight or curved jaw
transverse grooves over entire length of jaw
controls point bleeders
smallest

Crile hemostatic forceps

straight or curved jaws
transverse grooves over entire length of jaw
larger than mosquitoes

Kelly hemostatic forceps

straight or curved jaw
transverse groove only on distal end of jaw
same size as Criles, larger than Mosquitos

Rochester-Carmalt hemostatic forceps

longitudinal grooves along jaw
cross-striations at the tip
ligation of uterine stump and ovarian pedicles
used for larger pedicles that contain fat and blood vessels

Allis tissue forceps

Grasping

for firmly grasping tissues that will be removed
grasps fascial planes
NEVER use on skin or soft tissues staying in the body
interlocking sharp teeth at tip (can be traumatic)

Doyen intestinal forceps

Grasping

long, thin jaws –> bowed in center = gap
longitudinal grooves entire length of jaw
atraumatic: used for intestinal occlusion

Needle holders

Grasp and manipulate curved needles

Mayo-Hegar: most common, do not have scissors in the jaw
Olsen-Hegar: combo needle holder and scissors

Retractors

Manual and self-retaining - used to retract tissues - improve visibility at surgical site

Manual retractors

- Senn; retract skin and superficial muscle layers (smaller tips) - Army Navy: bigger, one blade is long the other short --> long blade holds deeper tissues back - Meyerding: ortho - Ribbon malleable: various lengths/widths, used in abdominal and thoracic surgery

Self-retaining retractors

- Gelpi: tips are sharp and angled out, ortho/neurologic - Weitlaner: superficial soft tissue - Balfour: abdomen - Finochietto: thorax

Suction tips

- Frazier: decompression hold to control suction - Poole: multiple openings at its tip reduces omental plugging - Yankauer: large volumes, not fine suction (bigger than Frazier)

Spay hook

Snook ovariohysterectomy hook | - retrieval of uterine horn

Towel clamps

- Backhaus: sharp pointed, secure drapes to skin | - Lorna: non-penetrating, secure equipment to the drapes

Stapling equipment

- skin - GIA: gastrointestinal anastomosis - TA

Are electrosurgical units cautery?

NO - monopolar: ground plate under patient, doesn't work in wet environment - bipolar: current does not go thru patient, will work in presence of blood

Use _____ to grasp the backbone of the scalpel blade

Needle holders

Handing instruments to surgeon

- handle first --> place in palm - face curved tip up - keep sharp or jabbing surfaces away from surgeon - place in hand in definitive way
