Flashcards in L02: Surgical Instrumentation (Case) Deck (34):
1

least traumatic method for incising tissue

scalpel

2

#15 scalpel blade used for:

small animals ie. cat skin, cutting into bowel/bladder, etc.

3

#12 scalpel blade used for:

dissection around something like for dehorning or declawing

4

#11 scalpel blade used for:

puncturing bowel, joint capsule, small ureters, etc.

5

#10 scalpel blade used for:

skin and viscera; cuts deeper with less pressure

6

2 acceptable grips for scalpel

fingertip grip
pencil grip

7

purposes of scissors

dissection or sharp cutting

8

disadv. of scissors

inc. tissue trauma due to shearing forces

9

adv. of scissors

ease of cutting redundant tissue
improved visibility and control

10

adv. of curved vs. straight scissors

curved improve control and visibility

11

3 main types of scissors

blunt/blunt
sharp/blunt
sharp/sharp

12

purpose of tissue forceps

tissue manipulation with non-dominant hand
-use pencil grip

13

chars. of tissue forceps

tweezer-like
pointed tips for manipulation of CT
atraumatic serrated tips used for blood vessel manipulation

14

Debakey forceps used for:

to grasp viscera; have gentle hold with mild serations

15

Which more traumatic: Rat Tooth or Brown-Adson

brown-adson (because have to crush to grab the skin)

16

Rat tooth tissue thumb forceps aka

Adson tissue thumb forceps

17

Which clamps are crushing and which are non-crushing

crushing: Hasted mosquito, Rochester carmalt
non-crushing: Doyen intestinal clamp

18

main fx of Halsted mosquito clamp

used to crush vessels; teeth go horizontal, which should be applied perpendicular to vessels

19

main fx of Rochester carmalt clamp

crushes collagen-dense tissues like uterine body; grooves go parallel

20

main fx of Doyen intestinal clamp

to atraumatically hold off bowel

21

selection of needle holders

-depends on size of needle being manipulated, NOT surgeon size
-longer needle holders increase power (have longer moment arm)
-shorter needle holders increase precision

22

use for Mayo Hegar needle holders

suturing body wall, large dog bladder, etc.

23

use for Ryder needle holders

(shorter than Mayo Hegar)
-small dog/cat bladders, ureter sutures, etc.

24

use for Microvascular needle holders

cystotomies, etc.

25

3 grip styles for needle holders

1) Thumb-third finger or "tripod" grip (used in lab)
-slower, more precise
2) Thenar-eminence grip
3) Palm grip
-2 and 3 are faster, less precise

26

purpose of retractors

retraction of neurovascular structures, muscle, bone

27

2 classes of retractors

self-retaining
hand-held

28

use of Finochietto retractor

retraction of sternum, ribs

29

Know what Gosset, Pediatric Balfour, Large Balfour, Hohmann, Malleable retractors look like

:)

30

use of Hohmann retractors

looking into joints

31

purpose of suction tips

removal of blood or fluid from operative site
-can be traumatic to tissues if used inappropriately

32

know what Yankauer, Poole, Adson, Frasier suction tips look like

(slide 42)

33

to avoid instrument corrosion:

-open any hinged instruments before cleaning
-rinse immediately after use
-no distilled or tap water
-NO SALINE (causes pitting)
-hand scrub soil
-use instrument washer

34

properties of instrument milk

H2O based
antimicrobial
lubricant
