ring retractor with self-retaining ratchet
used for retraction of soft tissues (esp muscle bellies during orthopedic or spinal surgery)
sharp tips, caution
Weitlaner Retractor
ringed retractor with self-retaining ratchet
multiple pointed prongs on each arm
useful for retraction of soft tissue in small, superficial incision
must take care with tips and soft tissue
Army-Navy Retractor
double ended blunt retractor blades differ in length
hand hel retractor typically used by assistant
soft tissue and orthopedic surgery
Malleable Retractor
double ended blunt retractor
various sizes
can be bent at various angles
used for retracting viscera in abdominal and thoracic surgery

soft tissue and orthopedic surgery for retraction of tissues in small working spaces
hand held retractor typically used by assistant
Snook Hook/Spay Hook
flat, thin handle allows for better visualization of tissue
can be used to retract thinner layers of superficial tissue
Kern bone Holding forceps
grip and manipulate bone during fracture repair/reduction
jaws are serrated with grasping points at tips to promote strong grip on bone
ratcheted handle with quick release lever
Speed lock bone holding forceps
used to grip and manipulate bone during fracture reduction/repair
tips can be serrated or pointed
locking mechanism easily manipulated with fingers
Jacob’s Chuck
used to drive IM pins and K wires during orthopedic surgery
key used to tighten or release pin grip
Mallet
metal or nylon capped
used in orthopedic surgery to advance an osteotome for making precise osteotomies
Osteotome and Chisel
osteotome is bevelled on both sides and a chisel is bevelled on one side- osteotomes are used more commonly
used to create osteotomy in numerous orthopedic procedures
Freer Periosteal Elevator
small periosteal elevator
double ended
standard
Periosteal elevator
used to reflect muscle and soft tissue from bone
various sizes with round or straight edges
Lampert Rongeur
forceps with cupped jaws and blunted or tapered tips
used to remove small fragments of bone, to recontour bone or to prepare bone for grafting
jaws may be straight, curved or angled
