Eyed Needles

28
Q

Type of needle that will not unthread itself and carries less bulk through the hole (atraumatic)
Readily available, always sharp, and comes with suture material attached
Cons: More expensive and can’t be reused

A

Swaged/Swedged

29
Q

Faster and easier to use than hand suturing

33
Q

Type of stapler used the same way as GIA but used in lung resection
Double or triple row

A

Thoracoabdominal stapler (TA)

34
Q

A

3/8 and 1/2 circle

41
Q

43
Q

Needle point in which the needle dissects through friable tissue without cutting and generally recommended for suturing

Turns tissue outward, away from pt and toward the surgeon

A

Everting

50
Q

Turns the tissue toward the pt/ toward the lumen of hollow, viscous organ

A

Inverting

51
Q

Designed to bring tissues in direction apposition

A

Apposing

52
Q

Suture pattern used in skin, SQ, fascia, blood vessels, and GI
Less strength than simple interrupted and has excessive tension that causes puckering and strangulation of tissue

A

Simple continuous

53
Q

Suture pattern used in skin, SQ, fascia, blood vessels, nerves, GI
Provides secure closure and excessive tension that can cause inversion

A

Simple Interrupted

54
Q

Suture pattern used in skin and fascia and stronger closure than simple interrupted
Resists tension and prevents eversion
Faster to apply

A

Interrupted cruciate

55
Q

Suture pattern used in skin and diaphragm (large animals)

Similar to continuous but provides security if broken

A

Ford Interlocking

56
Q

Suture pattern used in skin, fascia, muscle, and tendon

Stump is held inverted as suture is tightened

A

Purse string

58
Q

Suture pattern used for manipulation or retraction of tissue

2 or more are placed

A

Stray sutures

59
Q

Suture pattern where suture material is passed through the stump to be ligated around half of the stump then around the entire stump
Prevents suture from slipping off the stump and prevent hemorrhage
