2
Q

Types of thumb forceps and there uses:

Brown-Adson forceps  two longitudinal rows of small, fine, intermeshing teeth  broad but delicate tissue grip
Russian forceps  broad, round tip with grooved perimeter and concave center
DeBakey and Cooley forceps  longitudinal grooves and fine horizontal striations  used for vascular, thoracic, and intestinal surgeries

3

Doyen-DeBakey intestinal forceps are the least traumatic to tissue
Babcock intestinal forceps are also considered less traumatic.
Kelly, Rochester-Oschner, and Rochester-Carmalt are all hemostatic forceps, and therefore are “crushing” forceps

56
Q

T/F: Depth  control  with  the  electro  scalpel  is  more  precise  than    with  the  cold  scalpel. 

A

False; Depth  control  with  the  electro  scalpel  is  less  precise  than    with  the  cold  scalpel.  Because  the  electrode  cuts  all  tissue    it contacts, visual control is of paramount importance. Electrosurgical incision should not be used in areas with poorly defined  anatomic planes. Thermal necrosis at the wound edges can be  reduced and depth control can be improved by using the lowest  setting on the controls that allows clean cutting.
