INSTRUMENTS aidot Flashcards
-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
-Olsen-Hegar

-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
-Dressing forceps
-thumb 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
-Adson forceps
-thumb forceps
-GRASPING tissue forceps
-one teeth both sides
-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
-Brown - Adson forceps
-FORCEPS
-thumb forceps
-many teeth
-grasp tissue and inanimate object

-longer
-for drapes
-Jones towel clamps
-MISCELLANEOUS instrument
-towel clamps
-short and small
-for drapes
-Mayo scissors
-CUTTING instrument
-straight scissors: mechanical advantage for cutting dense tissue
-thick blades
-blades are 1/3 of the length
-dissecting SOFT tissue
-Tenotomy scissors
-CUTTING instrument
-straight scissors: mechanical advantage for cutting dense tissue
-delicate and accurate procedures
-eye surgery, orthopedic, plastic surgery
-Weitlaner retractor
-RETRACTOR
-self-retaining retractors
-improve exposure by deflecting tissue away from area of interest
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
-Gelpi retractor
-RETRACTOR
-self retaining retractor
-improve exposure by deflecting tissue away from area of interest
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
-Kelly hemostats
-GRASPING instrument
-HEMOSTATIC forceps
-clamp blood vessel
-crushing
- 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
-Doyen intestinal forceps
-GRASPING instrument
-induce tissue trauma, thus non-crushing tissue forceps
-grasp tissue
- Multiple types of forceps of various sizes and shapes available
- Used for a variety of tasks
- Configuration of jaw serrations determines their use
- Cross-serrations– tip-clamping
- Longitudinal serrations– jaw-clamping
-Allis tissue forcceps
-GRASPING instruments
-CRUSHING tissue forceps
-should be used to grasp ONLY tissue slated FOR EXCISION
- Multiple types of forceps of various sizes and shapes available
- Used for a variety of tasks
- Configuration of jaw serrations determines their use
- Cross-serrations– tip-clamping
- Longitudinal serrations– jaw-clamping
