Background: From Major Abdominal Operations to Minimally Invasive Endoscopic Surgery
With the introduction of laparoscopic cholecystectomy (minimally invasive
surgical gallbladder removal) in the 1990s, laparoscopic or minimally invasive
surgery has become widely accepted due to its reduced impact on patients.
Recently, laparoscopic applications have expanded to surgeries requiring
advanced technology, such as operations on malignant tumors and bariatric
surgeries. Moreover, an increasing demand for these procedures can be
expected in the future due to the spread of colorectal cancer and obesity in
the global population.
To improve the efficiency of these operations as well as promote their
widespread acceptance and use, we developed a single-energy device
capable of multiple, complex tasks. Our innovation, THUNDERBEAT, enables
not only vessel sealing, hemostasis, and tissue coagulation but also precise
dissection and cutting, which is made possible by the jaw tip’s precision
design. In addition, the combination of THUNDERBEAT with high-resolution
endoscopic imagery is expected to enable far more precise and effective
surgical procedures.
To contribute value to society, Olympus will continue to advance
minimally invasive solutions with a “see and treat” approach. By integrating
observation, diagnosis, and treatment technologies, we strive to enhance lives
around the globe.
Product Features: Hemostatic Function and an Unprecedented Incision Speed for Improved Surgical Efficiency
We were motivated to work toward a single device that could meet surgeons’
demands for superior medical effectiveness and efficiency through safer, swifter
incisions, and convenient, reliable vessel sealing to minimize blood loss.
THUNDERBEAT Features
1. Simple operation delivering unprecedented incision speeds
2. Reliable sealing of blood vessels up to and including 7 mm in diameter
3. Integrated delivery via a single device capable of multiple tasks, including
incision, tissue removal, blood vessel sealing, and hemostasis
With a robust average growth rate for the surgical energy device market of
14% per year (source: Olympus internal study), the market scale for the fiscal
year ended March 31, 2011, reached about US$1.4 billion.
Two U.S. manufacturers currently account for more than 80% of the
global market share (source: Olympus internal study). By contrast, while
Olympus holds the top position among Japanese manufacturers, our share of
the global market is only about 13%.
By creating new markets based on our overwhelming and inimitable
technological edge, and by maximizing the power of the Olympus sales
network (bolstered by our acquisition of Gyrus ACMI), we expect to achieve
steady future gains in the surgical arena.
