1

What is electrosurgery
dont use around ______

sterile electrode w + current destroys tissue and coagulates BV
ETOH, flammable materials, metal implants, jewelry

2

Electrocautery

indirect electrical current, no blood loss

3

Hyfrecation

direct, high freq current flows through tissue to generate heat. quick effective w minimal blood loss and great precision

4

Tissue biopsy: Excisional
type of blade, angle, shape, and parallel to _______

3-1 elliptical w 30 degree angle corners using # 15 blade - parallel to Langer's Lines

5

Scalpes # 11

pucture abscess, incisions, stabbign

6

#15

blunt dissection, excision, trimming

7

#10

like 15 for thick skin

8

#3

disposable, sterile, attached to reusable handle

9

Types of forceps: tooth vs toothless

toothless crushes skin, foreign body removal

- depigmentatio
- CI malign, raynauds, sensitive skin

26

bipolar vs unipolar

requires pad to complete circuit
no second electrode needed
