Olympus has launched two new jaw designs in the Powerseal Sealer/Divider range of advanced bipolar surgical energy products: the Powerseal Straight Jaw, Double-action (SJDA) and the Powerseal Curved Jaw, Single-action (CJSA). The first Powerseal device, launched in 2021, is the Powerseal Curved Jaw, Double-action (CJDA), which has established a strong foothold for Olympus in the advanced bipolar surgical energy market.
The Powerseal Sealer/Divider family of devices now includes three jaw designs each available in three shaft lengths to support surgeon preference and technique for dissection, grasping and sealing during surgical procedures. These devices are designed to meet the highest standards of clinical performance for advanced bipolar surgical energy devices by consistently delivering secure and fast vessel sealing, the company claims. The devices are designed to promote procedural efficiency and surgeon comfort with a multifunctional feature set and carefully considered ergonomics. Each Powerseal design requires less squeeze force than competitor devices to close the jaws, without sacrificing jaw force or sealing capability.
The Powerseal devices augment an already extensive and diverse surgical energy portfolio, which features the Thunderbeat hybrid energy devices and Sonicbeat ultrasonic dissectors.
The company claims Powerseal devices provide surgeons with reliable sealing, dissection and grasping capabilities in laparoscopic or open surgery while reducing the force required by the surgeon to close the jaws. The Powerseal devices are indicated for use in numerous surgical procedures including bariatric, general surgery, gynaecological, colorectal, urological, thoracic and vascular procedures.
The Powerseal single-use devices are designed with features including:
Confident vessel sealing: Strong and efficient sealing of vessels, including pulmonary vessels, tissue bundles, and lymphatics, up to and including 7mm.
Greater than 99% probability of vessel burst pressure above 360 mmHg, regardless of vessel size ≤7mm.
Minimised tissue sticking on par with nano-coated products. In pre-launch clinical cases, 97% of surgeons indicated that the number of jaw cleanings required with Powerseal is equivalent, fewer or substantially fewer than required by their current energy device.
Multifunctional capabilities: Three jaw designs support the surgeon's preference and technique for dissection, grasping, and sealing. All Powerseal jaw styles are available in three shaft lengths for laparoscopic and open procedures.
Energy activation without the requirement to fully close the jaws facilitates spot coagulation of surface bleeders or activation on thick tissue, when desired.
Increased dissection force supports separation of tissue planes during dissection.
Ergonomic comfort: Reduced distance to device controls, e.g. jaw lever and energy activation button, reduced squeeze forces, smooth jaw rotation, and a contoured handle are designed to promote comfort and ease of use.
Each Powerseal Sealer/Divider requires less squeeze force to close the jaws without sacrificing jaw force or sealing capability.
"We are very excited to expand our advanced bipolar surgical energy portfolio with the addition of these two new Powerseal devices. Meeting physician needs continues to be the primary driver of the product design and functionality," said Phil Roy, Global Vice President and General Manager for Surgical Devices in the Therapeutic Solutions Division of Olympus Corporation. "Powerseal devices are developed with a commitment to meeting our goals of sealing strength, efficiency and physician comfort."
Advanced bipolar energy devices are distinguished from traditional bipolar energy devices through regulating energy delivery, continuous tissue monitoring, and uniform pressure applied to the tissue by the device jaws. These attributes enable advanced bipolar technologies to deliver more consistent (7mm) vessel sealing than standard bipolar technology counterparts.
The new Powerseal SJDA and CJSA devices are regulatory cleared for sale in the US, Puerto Rico, Canada, Australia, the EU and Thailand at this time. The Powerseal CJDA device is being sold in all global regions, except China.
