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
The only PROXIMATE Linear cutter (TLC) that comes with a gold reload is:
PROXIMATE TLC75
The PROXIMATE TX stapler is available in the following sizes:
30mm & 60mm
Which of the types of open surgeries listed here can PROXIMATE relodable staplers be used in?
ALL OF THE ABOVE
What are are the 3 key features of PROXIMATE TLC Linear cutter?
CAM MECHANISM, INTERMEDIATE LOCKING, TISSUE RETAINING PIN

What area of the patients body can the ECHELON CONTOUR curved cutter allow better access and visibility to?
PELVIS
Which of the following statements is FALSE regarding the ECHELON CONTOUR Curved cutters tissue retaining pin?
ONLY WORKS IF THE TARGET TISSUE FITS ENTIRELY WITHIN THE JAWS OF THE DEVICE
The unique curved head of the ECHELON Contour curved cutter allows for pelvic access with the placement of a ______mm cut line in the width of a ____mm space.

6
The main competitor to ECHELON CONTOUR curved cutter is covidien,Medtronic’s:
Radial reload with Tri-staple technology
Transection and resections in colorectal surgical procedures, specifically in a ______ can be challenging because surgeons need to access deep in the pelvis.
LOW ANTERIOR RESECTION
Including a refreshed branding, the ECHELON CONTOUR curved cutter also included which TWO key features not available in the legacy CONTOUR. (Select all that apply)
