| Abstract |
Ultrasonic energy devices are essential for effective hemostasis during endoscopic surgery. Ultrasonic tissue transection occurs as a result of mechanical friction between the oscillating blade and the tissue. We hypothesized that blade surface structures and characteristics would affect tissue transection and sealing. The aim of this study was to clarify the efficacy of blade surface structures and characteristics in vessel sealing with an ultrasonic vibration. We developed an ultrasonic energy device with 50-kHz vibration frequency and 50 μm amplitude. We manufactured four types of blade surface of the ultrasonic device using microprocessing technology: (1) a non-coated blade without microgrooves, (2) a non-coated blade with microgrooves, (3) a water-repellent-coated blade without microgrooves, and (4) a water-repellent-coated blade with microgrooves. We compared the performance of the four devices and a commercially available ultrasonic device with a non-coated blade without microgrooves in an ex vivo vessel-sealing experiment. We sealed porcine carotid arteries (3-5 mm diameter) using each device 20 times. The cutting time of the water-repellent-coated blade with microgrooves was the shortest (11.0 ± 3.4 s); however, it did not differ significantly from that of the commercial ultrasonic device (12.9 ± 2.9 s, p = 0.73). The burst pressure of the water-repellent-coated blade without microgrooves (1456 ± 425 mmHg) was significantly higher than that of the commercial ultrasonic device (966 ± 559 mmHg, p = 0.04). The sealing failure rate of the water-repellent blade with microgrooves was the lowest of all devices (0 %). Instrumental sticking of tissue decreased in the water-repellent devices. The sealing width was not significantly different. The surface-processing of microgrooves and water-repellent coatings will improve the potential of ultrasonic devices with a fast transection and a high sealing reliability. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 January 2017.
All research outputs
#18,464,797
of 22,879,161 outputs
Outputs from Surgical Endoscopy
#4,762
of 6,053 outputs
Outputs of similar age
#267,570
of 352,770 outputs
Outputs of similar age from Surgical Endoscopy
#146
of 170 outputs
Altmetric has tracked 22,879,161 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,053 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 6th percentile – i.e., 6% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 352,770 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 170 others from the same source and published within six weeks on either side of this one. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
