Allows the user to control the amount of compression applied depending on tissue conditions
Controlled Tissue Compression and Adjustable Height Staple Technology are designed to deliver optimal compression needed for a secure anastomosis and effective perfusion to promote healing.
More tissue control
Anvil shaft passes through tissue without catching as the device is closed
The continuously smooth anvil shaft creates less excess tissue draw during anvil closure compared to the Covidien DST SeriesTM EEATM.*
Fixed anvil for predictable tissue interaction as device is opened
The fixed anvil design causes less tension on the anastomosis with less strain on the staple line during opening compared to the Covidien DST Series EEA.¥
More device feedback
Breakaway washer for distinct audible and tactile feedback during firing
The breakaway washer provides 5x more tactile feedback‡ and 16x more audible feedback§ compared to the Covidien DST Series EEA.
* 3.9x less excess tissue draw in benchtop testing on porcine jejunum. Comparing mean tissue draw during anvil closing of the ETHICON Circular Stapler (CDH25A) and the DST Series™ EEA™ Circular Stapler (EEAXL25). 0.437cm vs 1.708cm, p<0.05
¥ 1.4x less strain on the staple line in benchtop testing on porcine jejunum. Comparing mean tissue stretch during anvil opening after firing of the ETHICON Circular Stapler (CDH25A) and the DST Series™ EEA™ Circular Stapler (EEA25). 1.558cm vs 2.228cm, p<0.05
‡ Benchtop testing comparing average vibration measured as mean vectorial acceleration during firing. CDH 16.58 m/s2 vs. EEA 3.20 m/s2
§ Benchtop testing comparing mean peak sound intensity during firing. CDH 109.80 dB(linear) vs. EEA 95.27 dB(linear)
