Device Story

Manual surgical staplers for tissue transection, resection, and anastomosis creation. Devices include circular, linear, and transverse cutters/staplers. Operation involves manual handle activation to place titanium staples in staggered rows while simultaneously cutting tissue with integrated circular or linear knives. Used in OR settings by surgeons for gastrointestinal, gynecologic, thoracic, urologic, and pediatric procedures. Some models support reloading for multiple firings per procedure. Output is a stapled, transected tissue line, facilitating surgical closure and healing. Benefits include standardized, reliable tissue approximation and reduced procedure time compared to manual suturing.

Clinical Evidence

No clinical data. Bench testing only. Performance verified via porcine intestine/stomach models evaluating pressure resistance, staple formation, closed staple height, and firing force. Biocompatibility verified via cytotoxicity, skin sensitization, and irritation testing per ISO 10993.

Technological Characteristics

Manual surgical staplers using unalloyed titanium staples, polycarbonate, and stainless steel. Features include linear or circular knives, safety mechanisms (reset knobs/buttons), and various staple heights (0.75mm–5.5mm). Sterilized via irradiation. Complies with 21 CFR 878.4750.

Indications for Use

Indicated for patients undergoing open or minimally invasive general, gynecologic, urologic, thoracic, or pediatric surgical procedures requiring tissue transection, resection, or creation of anastomoses, including treatment of hemorrhoidal disease and occlusion of the left atrial appendage.

Substantially Equivalent (SE) Conclusion Biocompatibility testing was performed on the proposed devices; including cytotoxicity, skin sensitization and irritation tests. The test results demonstrate that the device does not introduce any biocompatibility concerns. The proposed device is sterilized by radiation, a different method than the predicate, and sterility was established per ISO ISO11137. Therefore, testing demonstrates that the difference in patient contact material and sterilization method will not affect substantial equivalence. The performance tests include pressure resistance test which is intended evaluate integrity of staple line, force to fire a stapler test which is intended to evaluate the force to fire a stapler, staple formation test which is intended to evaluate stapler formation characteristics, and closed staple height test which is intended evaluate whether the closed staple height can meet pre-defined criteria. The test results for both proposed device and predicate device was analyzed by statistical methods to ensure the sample size was appropriate to detect a meaningful difference between testing groups. The results show that there are no significant difference between proposed device and predicate device. Based on the comparison and performance test result analysis above, the proposed devices are determined to be Substantially Equivalent (SE) to the predicate devices.
