Question 1

Answer 1

-Mathieu
-needle holder

• Jaws short and frequently have grooves that are cross-hatched on the
  surface intended to limit twisting and rotation of the needle
• Should match both the size and the type of the needle being used
• Different locking mechanisms possible
• Needles placed perpendicular to the needle holder– greatest
  maneuverability
• Needle is generally grasped near its center

Question 2

Answer 2

-Olsen-Hegar
-needle holder

• Jaws short and frequently have grooves that are cross-hatched on the
  surface intended to limit twisting and rotation of the needle
• Should match both the size and the type of the needle being used
• Different locking mechanisms possible
• Needles placed perpendicular to the needle holder– greatest
  maneuverability

Question 3

Answer 3

-Crile hemostats
-HEMOSTATIC forceps
-clamp blood vessel-crushing

Hemostatic forceps
* Crushing instruments used to clamp blood vessels
* Serrations on the jaws may be transverse, longitudinal, diagonal, or a
combination of these
* Longitudinal serrations are generally gentler to tissue than cross-
serrations
* As little tissue as possible should be grasped to minimize trauma
* The least amount and duration of pressure applied by closure of the
ratchet on the instrument is the goal

Question 4

Answer 4

-Dressing forceps

-tweezer - like , nonblocking instruments used to grasp tissue and inanimate object

Thumb forceps
* Tweezer-like, nonlocking instruments used to grasp tissue (and
inanimate objects)
* Available in various shapes and sizes; tips may be pointed, flat, round,
smooth, or serrated with small or large teeth
* Pencil grip preferred
* Can be held in the palm of the nondominant hand when temporarily
not in use

Retractors
* Help improve exposure by deflecting tissue away from the area of
interest
* Available in hand-held and self-retaining varieties
* Some handheld retractors may be bent to conform to the area of the
body being retracted
* Moistened towels or pads are frequently placed under self-retaining
and selected hand-held retractors to minimize trauma and drying

Retractors
* Help improve exposure by deflecting tissue away from the area of
interest
* Available in hand-held and self-retaining varieties
* Some handheld retractors may be bent to conform to the area of the
body being retracted
* Moistened towels or pads are frequently placed under self-retaining
and selected hand-held retractors to minimize trauma and drying
