HARMONIC® 1100 Shears

HARMONIC® devices are the undisputed ultrasonic leader proven to minimize the impact on tissue.* 

HARMONIC 1100 Shears is designed for faster transection speeds, lower maximum blade temperature, and more precise tissue dissection.

HARMONIC® 1100 Shears

Features & Benefits

Harmonic 1100 Shears had 35% faster transection speeds than Harmonic ACE+7 for shorter heat exposure

Faster transection speed

Reduce heat exposure on tissue with transection speeds 35% faster when using the Energy buttonand 40% faster when transecting vessels 5-7mm in diameter using Advanced Hemostasis mode.§

Improved Adaptive Tissue Technology actively controls energy delivery to maintain a lower maximum blade temperature

Lower Maximum Blade Temperature

Achieve greater control with lower maximum blade temperature. HARMONIC 1100 Shears has an improved Adaptive Tissue Technology algorithm that actively controls blade heat which may protect surrounding tissue and vital structures.β

Curved, tapered blade geometry mirrors a mechanical dissector, delivering superior dissection among advanced energy device

More Precise Tissue Dissection

Curved, tapered tip that enables more precise dissection than HARMONIC ACE® +7 Shears.  Its unique shape mimics a mechanical dissector and may reduce the need to use a separate dedicated dissecting instrument.\\
