Harmonic Flashcards
The amount of blade displacement in ultrasonic devices determiners the type of tissue effect. Decreased blade displacement leads to increased ____ effect and increased blade displacement leads to increased
Coagulation, cutting
What are the 5 factors in harmonic technology that affect sealing and cutting capabilities?
Tissue tension, blade location, blade sharpness, blade pressure, power level
With harmonic ultrasonic technology, _____ is converted to _____ in the_____.
Electrical energy, mechanical motion, Hand piece
Which action below is NOT. Reason why harmonic decides are considered multifunctional?
They can articulate
During a gastrectomy using harmonic ACE+7, a surgeon wishes to increase cutting speed when mobilizing the stomach in a avascular planes. You should suggest he use the:
Distal portion of the blade using the MAX power level setting
Harmonic devices cut and coagulate simultaneously, but surgeons may choose to cut more than coagulate or coagulate more than cut by changing the power level. TRUE OR FALSE
TRUE
When decreasing the power level of Harmonic the result is a greater displacement of the active blade. TRUE OR FALSE
FALSE
When using harmonic devices, the MIN button prioritizes ____ and the MAX button prioritizes _____.
Coagulation, cutting
Which statement below about harmonic blades is CORRECT?
They should be connected to the HP054 hand piece (transducer) using a disposable hand switch with adapter
What are the 3 tip configurations for harmonic blades?
Curved blade, dissecting hook, ball coagulator
Dr. Lu is a GYN surgeon always interested in new devices and technology. One of his major concerns in his laparoscopic hysterectomy is the potential thermal damage when working around vital structures deep in the pelvis. What is the MOST SUITABLE feature of harmonic ace+ you can introduce to Dr. Lu?
Adaptive tissue technology
On the harmonic focus+ long shears with adaptive tissue technology, what is the vessel sealing indication?
Up to 5mm
Harmonic focus + was especially designed considering ______ needs.
Head and neck surgery
What benefit results from harmonic focus+ having a slimmer design?
Improved visualization and control in narrow spaces around delicate nerves
On the harmonic focus+ long shears with adaptive tissue technology, which are the easy to reach buttons available?
Max and MIN
Harmonic 1100 is designed for use exclusively with the Ethicon generator (GEN11) software Version _____ or later.
2018-1
The harmonic devices that feature adanvced hemostasis mode, and therefore can sell up to and including 7mm vessels, are:
Ace+7 and 1100
How does adaptive tissue technology help enhance tissue pad life in harmonic 1100 shears
It’s improved algorithm set the maximum blade temperature to just blow the point where tissue pads can potentially occur, and above where the desired tissue effects occur
The following are approved indications for the harmonic ace+ 7 shears with advanced hemostasis :
7mm vessel ligation, transection of soft tissuee
A thoracic surgeon told you she is always looking for ways to minimize the time spent on less critical steps in the procedure, such as dealing with adhesions. She also mentioned that create significant oozing as well as contribute to postoperative drainage. Which harmonic 1110 claim below would e the LEAST APPROPRIATE to respond her concerns?
Harmonic 1100 produces consistent and reliable hemostasis can be used in challenging hemostasis conditions,such as inflamed and/or fibrous tissue
What types of tissue can the harmonic 11000 shears be used on? (Select all that apply)
Vessels
Lymph nodes
Soft tissue
Which statement is FALSE about harmonic 1100 when compared to harmonic ace+ 7?
Harmonic 1100 had higher maximum blade temperature than ace+7
What is the benefit of harmonic 1100 shears having a curved, tapered blade geometry that mirrors a mechanical dissector?
Reduces he need to use a separate dedicated dissecting instrument
What are the main benefits of the refined blade design of harmonic ace+7 shears
Precision and multi functionality
Harmonic 1100 shears had transection speeds ____ % faster than harmonic ace+7 shears with advanced hemostasis for shorter heat exposure on tissue.
35%
You would recommend harmonic focus + long shears to a ____ surgeon performing a/an_____
General surgeon, open pancreatectomy
What is the maximum vessel sealing indication for harmonic focus+ curved shears?
5mm
Which is NOT a benefit of harmonic focus+ with adaptive tissue technology?
Rotation knob allows the shaft to rotate 360 for better maneuverability in tight spaces
The following are approved indications for the harmonic ace+ 7 shears with advanced hemostasis
7mm vessel ligation, transection of soft tissue
