RFQ – Request for Quotation

Q1: Can the HP35 stapler be used with all cartridge models, and what types of cartridges are available?
A: Yes, the HP35 stapler features universal cartridge compatibility, allowing the same gun body to adapt to all HP31A series cartridge models. These cartridges are available in 31 mm, 45 mm, and 60 mm anastomosis lengths, with staple heights ranging from 2.0 mm to 5.0 mm across multiple configurations (White, Blue, Green, Red, Purple, Turquoise). The cartridge selection should be based on the specific tissue thickness and resection length requirements of the procedure. This universal compatibility enables surgeons to switch between cartridge types during the same procedure without changing instruments, significantly reducing surgical time and costs.

Q2: What is the advantage of the 360° rotation and 45° articulation feature?
A: The 360° axial rotation and 45° left-right articulation provide exceptional versatility in accessing challenging anatomical locations. Surgeons can approach tissues from multiple angles without repositioning the instrument or altering the surgical approach, reducing the time required for tissue preparation and minimizing the risk of tissue damage during positioning. This feature is particularly valuable in complex procedures where access is limited or where the stapler needs to be positioned at an angle to achieve optimal tissue alignment. The wide range of motion also enhances the surgeon's ability to achieve the optimal firing angle, improving staple formation and reducing the risk of postoperative complications.

Q3: How does the Gecko Claw surface convex design improve staple performance?
A: The Gecko Claw surface convex design features a specialized pattern on the staple cartridge that reduces lateral and longitudinal oscillation of the staples during firing. This pattern creates a grip-like effect that keeps the tissue stable and prevents it from sliding during the critical firing process. This design ensures accurate staple placement and consistent staple formation, reducing the risk of staple malformation, tissue damage, and anastomotic leakage. The improved stability is particularly beneficial in thicker or more fibrous tissues where tissue slippage is more common.

Q4: What is the benefit of the advanced unequal staple height technology?
A: The advanced unequal staple height technology utilizes progressively varying staple heights along the cartridge to deliver perfect cutting and suturing while maintaining excellent blood supply to the anastomosis. The graduated staple heights are optimized for different tissue layers—shorter staples for secure hemostasis and longer staples for tissue approximation—ensuring optimal closure across the entire tissue thickness. This technology significantly improves the recovery rate after surgery by reducing the risk of ischemia, necrosis, and leakage at the anastomotic site.

Q5: What are the recommended sterilization methods for the HP35 stapler?
A: The HP35 stapler is a reusable device that can be sterilized between uses. We recommend steam sterilization at 134°C for 18 minutes, following the manufacturer's instructions for proper cleaning and maintenance. The device should be disassembled, thoroughly cleaned, and dried before sterilization to ensure effective sterilization. The stapler should be inspected for wear or damage before each use, and any damaged components should be replaced. The staple cartridges are single-use and supplied sterile; they should be discarded after each procedure.

Q6: What is the typical shelf life and storage condition for the staple cartridges?
A: The staple cartridges have a typical shelf life of 3–5 years from the date of manufacture, as indicated on the product labeling. They should be stored in a cool, dry environment away from direct sunlight and extreme temperatures. The sterile packaging should remain intact until the time of use to ensure sterility. We recommend checking the expiration date before use and disposing of any expired or damaged cartridges. For optimal performance, cartridges should be stored flat and not subjected to excessive pressure or impact that could deform the staple formation.
