Science Of Stapling/ Open Cutters Flashcards
Which of the following are important mechanical and/or biomedical properties of tissue that are important to consider for stapling?
ALL OF THE ABOVE
If a surgical fusion is too tight, it can result in:
ISCHEMIA
Tissue that is _____ tends to compress more over time:
HIGHLY VISCOUS
When tissue is compressed it:
SEPARATES THE SOLID AND LIQUIDS (WATER) AS THE WATER IS SQUEEZED OUT, IT LEAVES THE SOLID WHICH HELPS TO FORM BETTER STAPLES
______ and ______ are examples of thick tissue.
GASTRIC TISSUE AND LUNG PARENCHYMA
______ and ______ are examples of medium/thick tissue.
INTESTINES AND BRONCHUS
What is the firing stage of compression with ETHICON STAPLERS?
THE SECOND STAGE OF COMPRESSION WHEN THE STAPLER IS FIRED AND TISSUE IS COMPRESSED FURTHER
Ethicon designs its staplers to have adequate hemostasis. This is a balance between _____ and ____.
PERFUSION; ISCHEMIA
All surgical procedures require the fusion of tissue, or biologic repair? TRUE OR FALSE
TRUE
Which of these statements about collagen and how it play a key role in tissue fusion,is NOT accurate?
COLLAGEN IS THE THIRD MOST ABUNDANT PROTEIN IN THE HUMAN BODY
Because human tissue biphasic, what happens to it when it is compressed?
The liquid is exudate (squeezed out) leaving a smaller remaining solid, more appropriate in thickness for stapling
Controlled tissue compression requires the surgeon to fire the same staple height, regardless of of tissue variability. TRUE OR FALSE
FALSE
What is the pre-stage of compression with Ethicon staplers?
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.
When it comes to tissue compression, insufficient compression will potentially cause ischemia and tissue narcosis. TRUE OR FALSE
FALSE
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
TRUE
