The device description and performance studies focus on mechanical function and material properties, with no mention of AI/ML, image processing, or data-driven analysis.
Yes
The device is described as a surgical stapler used for creating anastomoses, resecting tissue, and treating hemorrhoids, all of which are therapeutic procedures.
No
Explanation: The provided text describes various types of surgical staplers used to create anastomoses, resect tissue, and treat hemorrhoids. These are surgical tools and do not perform any diagnostic function.
No
The device description clearly details physical, disposable surgical staplers made of titanium, which are hardware components. There is no mention of software as the primary or sole component of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes surgical procedures for creating anastomoses, treating hemorrhoids, and transecting/resecting tissue. These are all actions performed on the body, not on samples taken from the body for diagnostic purposes.
- Device Description: The device description details the mechanical function of stapling and cutting tissue. It does not mention any components or processes related to analyzing biological samples.
- Lack of IVD Indicators: There is no mention of analyzing blood, urine, tissue samples, or any other biological material for diagnostic purposes. The device's function is purely surgical.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
Disposable Circular Stapler places a double staggered, circular row of titanium staples upon activation, which was achieved by squeezing the handles firmly as far as they could go. Immediately after formation of the staples, the excess tissue will be resect by the circular knife, and then a circular anastomosis is created. The stapler are available in 25mm, 28mm, 29mm and 32mm five specifications. The staple is available in 4.5mm and 4.8mm two different heights.
Disposable Endoscopic Linear Cutter Stapler and Unit places two, triple-staggered rows of titanium staples and simultaneously divides the tissue from central line. The devices are available in 30mm, 45mm and 60mm three specifications. Reloads are available in 2.5mm, 4.0mm and 4.8mm four staple sizes to accommodate various tissue thicknesses. The device may be reloaded and fired up to 25 times in a single procedure.
Disposable Hemorrhoidal Stapler is a set of instruments that place a double staggered, circular row of titanium staples. Immediately after the formation of staples, the circular knife blade resects the excess of compressed mucosa. The stapler are available in 32mm, 33mm three specifications. The staple size is 3.8mm. It cannot be reloaded.
Disposable Linear Cutter Staplers and Reload places two double staggered rows of titanium staples and simultaneously cut and divides tissue between the two double rows. The devices are available in 55mm, 60mm, 75mm, 80mm and 100mm five specifications. Reloads are available in two staple sizes to accommodate various tissue thicknesses: 3.8mm and 4.8mm. It may be reloaded and fired up to 8 times in a single procedure.

Ex-vivo tissue test was conducted on porcine stomach and intestine tissue for both proposed device and predicate device to evaluate the device performance. The test items include Pressure Rest, Closed Staple Dimension Test, Staple Formation Test and Force Required to Fire Stapler Test. Besides tissue test, jugular vein test was conducted on a porcine model to evaluate the device performance in thin tissues. This test was conducted on both proposed device and predicate device for 2.5mm staple height. Burst pressure, closed staple height and staple formation were evaluated in jugular vein test.
