Cutting & Dissecting

 Cutting instruments have sharp edges.

They are used to dissect, incise, separate, or excise tissue.

 Most instrument sets will include #3

and #7 knife handles & suture, curved mayo, metz and tenotomy scissors.

slide-6
SLIDE 6

Knife Handles

 Come in various

widths & lengths

 Blades are attached

by slipping the slit in the blade into the groove on the handle

#7 #4 #3

slide-7

Knife Blades

 Blades with

numeric prefix of “1” (e.g., 10, 11, 12, 15) fit #3 or #7 handles

 Blades with the

numeric prefix “2” (e.g., 20, 21, 22, 23, 24) fit #4 handles

slide-8

Knife Blades

 #10 are used for

large skin incisions

 #15 are used for

short shallow incisions

 #11 are used for

initial skin puncture

  • f tiny deep

incisions

#10 #15 #11

Other Knife handles

 Long handles are

used inside deep incisions (e.g., open abdominal cases)

 Beaver knifes are

used for small delicate cases

Clamping & Occluding

These instruments are used to

apply pressure

Some clamps are designed to crush

the structure when applied

Others are noncrushing and are

used to occlude or secure tissue

Care & Handling of Instruments

slide-134
SLIDE 134

Handling instruments

 Instruments are placed firmly into the

surgeon’s palm in such a manner that it is ready of immediate use.

 Ringed instruments are handed with the box

locks closed.

 Curved instruments are passed with the

curve in the direction of intended use.

 To facilitate suturing the needle is

secured about 1/8 inch down from the tip of the needle holder and about a third of the distance from the eye or swaged end

slide-139
SLIDE 139

Care of Instruments

 During the procedure,

used instruments should wiped with a damp sponge or placed in a basin of sterile distilled water.

slide-140
SLIDE 140

Care of Instruments

 Do not saline on

instruments.

 Do not allow blood to

dry on instruments.

 Saline & blood can

damage instrument surfaces causing corrosion and pitting.

slide-141
SLIDE 141

Care of Instruments

 Flush suction tips with

sterile distilled water periodically to keep lumens patent.

 Flush all lumened

instruments thoroughly at the end

  • f case to prevent

blood from drying inside lumens.

slide-142
SLIDE 142

Care of Instruments

 Powered hand

pieces and batteries should not be immersed in liquid as this could damage internal mechanisms.
