The components of subject device and predicate devices both include inner stylet, cutting cannula, operating handle, actuation button, and depth stopper, but they are named differently. The function of components of subject devices are the same. The differences in design do not affect the safety and effectiveness of product. In sum, subject device and predicate devices have similar structure. - Difference 2: Nominal length of Cutting Cannula It can be seen from the table above that subject device provides more selections on the nominal length of Cutting Cannula, namely 80mm, 130mm and 180mm. Considering the different shape of patients and the distance between needle insertion point and lesion, 80mm. 130mm and 180mm are provided by subject device. Besides, 80mm and 180mm are within the length range (60mm to 250mm) of predicate devices. So this difference does not affect the safety and effectiveness of device. - Difference 3: Length of sample notch {12}------------------------------------------------ The length of subject device is 18.5 mm, and the length of sample notch of predicate devices are 18mm, 19mm and 20mm. Although the lengths are not the same, the length of within the length range of predicate devices. So this difference does not affect the safety and effectiveness of device. ### Conclusion Comparison of the device in question with the predicate devices K141552 is performed, and comparison items include indications for use, operation mechanics, material of paient, component, body contact site, structure, visualization technique, nominal length of Cutting Cannula, needle size, length of sample notch, biocompatibility, sterilization method and single we. It can be concluded that subject device and predicate device perform the same clinical conditions. The differences between the subject device and predicate devices do not affect the safety and effectiveness. Therefore, they can be considered as equivalent devices. {13}------------------------------------------------ | Comparison<br>Elements | Subject Device | Predicate Device | Comment | |------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------| | Proprietary Name | Semi-Automatic Core Biopsy Instrument | Bard® Mission® Disposable Core Biopsy<br>Instrument | - | | Classification<br>Regulation | 876.1075 | 876.1075 | Same | | Product Code | KNW | KNW | Same | | 510(k) Number | - | K171953 | - | | Indications for use | Semi-Automatic Core Biopsy Instrument is<br>intended for use in obtaining biopsies from soft<br>tissues such as lung, liver, spleen, kidney, prostate,<br>lymph nodes, breast, thyroid, and various soft<br>tissue tumors.

The components are both including the Inner stylet, Cutting cannula, fixed handle, Plunger, and Protective sheath with identical appearances, but named differently. Both products are designed with two firing positions and support single-handed operation. Major differences in structure Compared to Predicate device: - Fixed Handle: Fixed handle of Subject device adopts a structure of a rectangular cover shell and a base shell. Two complete circular a. rings are designed on the base shell to facilitate effective gripping during operation. In contrast, Predicate device features a symmetrical cover and base shell design, forming open semi-circular rings on both sides when combined, allowing effective gripping. {16}------------------------------------------------ - Safety Switch: Subject device includes a safety switch at the end of the fixed handle to prevent accidental firing during the puncture b. process, ensuring safe usage. - Window Design: The window of Subject device is marked with "10" and "20" indicator lines (with numbers) on both sides. When the C. plunger is pulled, a indicator line appears to show the firing length. Predicate device displays numbers ("(0", "10") directly within the window without using indicator lines. Above all, The subject device and predicate device have fundamental Scientific Technology, including Mechanism/Mode of Action, and Energy Used/Delivered. These differences changes of structure are ergonomically designed and do not affect the safety and effectiveness of the product. - Difference 2: Nominal length of Cutting Cannula ● Due to the different body shapes of patients and the different distances between different lesions and the needle entry point, clinical and market demand, subject product has increased 5 kinds of needle length of 8cm, 15cm and 18cm compared with the predicate product, this will not raise any safety issue. ### The above mentioned differences do not raise new questions of safety and effectiveness. ### Conclusion Comparison of the device in question with the predicate devices K171953 is performed, and comparison for use, operation mechanics, material of patient component, body contact site, structure, visualization technique, nominal length of Cutting Cannula, needle size, penetration depths, biocompatibility, sterlization method and single that subject device and predicate device perform the same finical conditions. The differences between the subject device and predicate devices do not affect the safety and effectiveness. Therefore, subject device can be considered as equivalent devices. {17}------------------------------------------------ | Comparison Elements | Subject Device | Predicate Device | Comment | |------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------| | Proprietary Name | Disposable Coaxial Biopsy Needle | BARD® TRUGUIDE® Disposable<br>Coaxial Biopsy Needle | - | | Classification Regulation | 876.1075 | 876.1075 | Same | | Product Code | KNW | KNW | Same | | 510(k) Number | - | K171953 | - | | Indications for use | Intended for use as a guiding needle in<br>obtaining core biopsy samples from soft<br>tissue such as lung, liver, spleen, kidney,<br>prostate, lymph nodes, breast, thyroid and<br>various soft tissue tumors.
