Q

right angle dissection forceps

A

delicate forceps with transverse ridges used for delicate grasping

used for very fine blunt dissection around delicate structures - NOT for general dissection

17
Q

mosquito hemostat forceps

A

transverse ridges
small and fine with short jaws
ratcheted

used for tip clamping of small bleeding vessels

18
Q

kelly/crile forceps

A

similar to mosquitoes

kelly: ridges stop halfway and the back half is smooth

crile: ridges run the full length of the jaw; larger than mosquitoes

19
Q

carmalt forceps

A

longitudinal ridges
large

used for jaw clamping of large vascular pedicles of mixed fat and vessels to facilitate mass ligation

20
Q

scalpel handle and blade sizes

A

handle: no 3
blades: no 10 or 15
- 10: longer blade curve
- 15: shorter blade curve

optimal cutting surface: maximal curvature of the blade

21
Q

metzenbaum scissors

A

delicate blades
long and thin
can be curved or straight

used for fine dissection of soft tissues
- NOT on tough fibrous tissue

22
Q

mayo scissors

A

thick blades

used for cutting heavy, tendinous, or fibrous tissues

23
Q

utility scissors

A

sharp - blunt blades

used for cutting non-tissue substances

24
Q

towel clamps

A

perforating instrument

used to fasten surgical drapes to patient’s skin

no crushing injury

25
Q

mayo hegar needle drivers

A

serrated grasping surface

no utility scissor at hinge

26
Q

Olsen hegar needle drivers

A

serrated grasping surface

utility scissor at hinge

27
Q

scalpel fingertip grip

A

handle held pinched between thumb and middle finger, index finger on top of the spine of the blade to apply pressure

flattens the angle with broad direction control

good for long, linear cuts

28
Q

pencil grip

A

handle held between the thumb and index finger

steepens the angle with fine direction control

good for shorter, more precise cuts with direction change

29
Q

forceps pencil grip

A

thumb and index finger control the forceps with instrument on top of hand

most secure hold

30
Q

tripod grip on ringed instruments

A

thumb and ring finger placed in the rings; index finger stabilizes the shank of the instrument

most stable

31
Q

palm grip for ringed instruments

A

instrument held in the palm of the hand without placing any fingers through the rings

good for suturing long, straight incisions

32
Q

tip clamping

A

minimizes the amount of surrounding tissue included in the clamp to reduce trauma

used with forceps that have transverse ridges

33
Q

jaw clamping

A

places selected tissues closer to the hinge of the instrument resulting in greater force transmission leading to more crushing/tissue trauma

used with forceps that have longitudinal ridges
