Key Advantages

The Electric Endoscopic Cutter Stapler offers a range of distinct clinical benefits that enhance surgical precision, efficiency, and patient outcomes.

Power-Driven Precision – The electric drive technology delivers consistent, uniform cutting speed that eliminates the manual shaking and tissue pulling associated with manual staplers. The powered mechanism ensures smooth, uninterrupted tissue transection, significantly reducing the risk of tissue trauma and postoperative complications.

Enhanced Jaw Pressure – The system incorporates new structural optimizations that provide significantly greater clamping force compared to conventional staplers. This enhanced jaw pressure effectively reduces tissue slippage during firing, ensuring accurate staple placement and secure anastomosis even in challenging tissue conditions. The improved pressure is particularly advantageous in thicker tissues where secure closure is critical.

Optimized Cutting and Stapling – The uniform cutting speed produces smooth, burr-free incisions that promote optimal healing and reduce the risk of postoperative leakage. The advanced staple formation ensures consistent, reliable tissue closure, with the staples forming a perfect B-shape that provides secure hemostasis and tissue approximation.

Versatile Sizing Options – Available in three shaft lengths (S: 192 mm, M: 252 mm, L: 352 mm) to accommodate different patient anatomies and surgical approaches. The system is compatible with both 45 mm and 60 mm staple cartridges, providing flexibility for different tissue widths and resection requirements.

Comprehensive Staple Height Selection – Staple cartridges are available in five staple heights (2.5 mm, 3.5 mm, 3.8 mm, 4.1 mm, and 4.3 mm), color-coded for rapid identification and selection. This comprehensive range accommodates the full spectrum of tissue thicknesses encountered in general, thoracic, and gynecological surgery.

Superior Tissue Handling – The enhanced jaw design and optimal clamping force ensure secure tissue positioning during firing, minimizing the risk of tissue slippage and misalignment. This is particularly important in minimally invasive procedures where visualization and access are limited.

Safe and Reliable Staple Formation – The system delivers consistent, reliable staple formation across all tissue types and thicknesses. The staples are formed into a perfect B-shape that provides secure tissue approximation while maintaining adequate blood supply to the anastomotic site, promoting optimal healing and reducing the risk of leakage or stricture.

RFQ – Request for Quotation

Q1: What is the difference between the HP20 and HP22 series staplers, and when should each be used?
A: The HP20 series is designed for use with 45 mm staple cartridges, making it suitable for most standard surgical procedures requiring shorter anastomosis lengths. The HP22 series is designed for use with 60 mm staple cartridges, providing longer anastomosis length (59.2 mm) for larger tissue resections. Both series are available in the same shaft lengths (192 mm, 252 mm, and 352 mm) and feature the same electric drive technology and enhanced jaw pressure. The choice between the two depends on the anastomosis length required for the specific surgical procedure.

Q2: How do I select the appropriate staple height for a given procedure?
A: Staple height selection should be based on the thickness of the tissue being stapled. The system includes a tissue thickness gauge that allows surgeons to assess tissue thickness before selecting the appropriate staple cartridge. As a general guide: 2.5 mm staples are suitable for thin tissues (vascular, thin mesentery); 3.5 mm for medium tissues (gastric, intestinal); 3.8 mm and 4.1 mm for thick tissues (stomach, lung); and 4.3 mm for very thick tissues (obese patients, thick mesentery). The color-coding system (White, Blue, Dark Blue, Green, Turquoise) enables rapid identification and selection. Using the correct staple height is essential for achieving optimal hemostasis and tissue healing.

Q3: What is the advantage of the electric drive system over manual staplers?
A: The electric drive system provides several significant advantages over manual staplers. First, it delivers consistent, uniform cutting speed that eliminates the manual shaking and tissue pulling that can occur with manual staplers, reducing tissue trauma. Second, the power-driven mechanism ensures smooth, uninterrupted cutting and stapling, producing smooth, burr-free incisions that promote optimal healing. Third, the electric system reduces the physical effort required from the surgeon, particularly important in prolonged or complex cases. Finally, the enhanced jaw pressure, made possible by the structural optimization of the powered mechanism, provides superior clamping force that reduces tissue slippage and improves staple formation.

Q4: Can the stapler be used in both laparoscopic and open surgery?
A: Yes, the Electric Endoscopic Cutter Stapler is suitable for both endoscopic (laparoscopic and thoracoscopic) and open surgical procedures. The device is designed with a long shaft (available in 192 mm, 252 mm, and 352 mm lengths) that provides excellent reach in minimally invasive procedures, while the ergonomic handle design ensures comfortable use in open surgery. The device can be inserted through standard trocars (typically 12 mm) or used directly in open surgical fields. The 360° rotating shaft and articulating tip (on select models) further enhance accessibility in challenging anatomical locations.

Q5: Are the staple cartridges interchangeable between different stapler models?
A: The staple cartridges are designed to be compatible with specific stapler families. The HP21 series cartridges (both 45 mm and 60 mm) are compatible with the HP20 and HP22 series staplers, as well as with the disposable endoscopic stapler (HP25 series) and the powered articulating stapler (HP31 series, HP31C series). However, cartridges from different manufacturers or incompatible product families should not be used as they may not fit correctly or may compromise staple formation and patient safety. We recommend using only genuine cartridges that are specifically labeled for use with your stapler model.

Q6: What is the standard packaging configuration and shelf life for the cartridges and staplers?
A: The stapler devices are supplied non-sterile and packaged individually in protective cases, while the staple cartridges are supplied sterile, single-use, and individually packaged in sterile blister packs. The shelf life for cartridges is typically 3–5 years from the date of manufacture. We recommend checking the expiration date before use. The stapler devices are reusable after appropriate sterilization according to the manufacturer's instructions. We recommend steam sterilization at 134°C for 18 minutes. Please refer to the product labeling for specific sterilization and shelf-life information.
