Answer 1

ALL OF THE ABOVE

Question 2

If a surgical fusion is too tight, it can result in:

Answer 2

ISCHEMIA

Question 3

Tissue that is _____ tends to compress more over time:

Answer 3

HIGHLY VISCOUS

Question 4

When tissue is compressed it:

Answer 4

SEPARATES THE SOLID AND LIQUIDS (WATER) AS THE WATER IS SQUEEZED OUT, IT LEAVES THE SOLID WHICH HELPS TO FORM BETTER STAPLES

Question 5

______ and ______ are examples of thick tissue.

Answer 5

GASTRIC TISSUE AND LUNG PARENCHYMA

Question 6

______ and ______ are examples of medium/thick tissue.

Answer 6

INTESTINES AND BRONCHUS

Question 7

What is the firing stage of compression with ETHICON STAPLERS?

Answer 7

THE SECOND STAGE OF COMPRESSION WHEN THE STAPLER IS FIRED AND TISSUE IS COMPRESSED FURTHER

Question 8

Ethicon designs its staplers to have adequate hemostasis. This is a balance between _____ and ____.

Answer 8

PERFUSION; ISCHEMIA

Question 9

All surgical procedures require the fusion of tissue, or biologic repair? TRUE OR FALSE

Answer 9

TRUE

Question 10

Which of these statements about collagen and how it play a key role in tissue fusion,is NOT accurate?

Answer 10

COLLAGEN IS THE THIRD MOST ABUNDANT PROTEIN IN THE HUMAN BODY

Question 11

Because human tissue biphasic, what happens to it when it is compressed?

Answer 11

The liquid is exudate (squeezed out) leaving a smaller remaining solid, more appropriate in thickness for stapling

Question 12

Controlled tissue compression requires the surgeon to fire the same staple height, regardless of of tissue variability. TRUE OR FALSE

Answer 12

FALSE

Question 13

What is the pre-stage of compression with Ethicon staplers?

Answer 13

The first stage of compression when the surgeon inserts the tissue into the jaws of the stapler and clamps down and waits 15 seconds. This forces fluid from the tissue and achieves a tissue thickness that is more appropriate for the selected closed staple height.

Question 14

When it comes to tissue compression, insufficient compression will potentially cause ischemia and tissue narcosis. TRUE OR FALSE

Answer 14

FALSE

Question 15

The goal of a stapling device is to create a series of properly formed staples that are properly formed in the shape of a B. TRUE OR FALSE

Answer 15

TRUE

Question 18

Which of the types of open surgeries listed here can PROXIMATE relodable staplers be used in?

Answer 18

ALL OF THE ABOVE

Question 19

What are are the 3 key features of PROXIMATE TLC Linear cutter?

Answer 19

CAM MECHANISM, INTERMEDIATE LOCKING, TISSUE RETAINING PIN

Question 20

What color staple cartridge options are available when using the TX Model of the PROXIMATES relodable stapler

Answer 20
