For use in endoscopic surgical procedures through cannulae to perform cutting, grasping, dissecting, retracting, and manipulating functions.
The K&W 2-Piece Take-Apart Instrumentation are endoscopic instruments which have jaws designed to cut, grasp, dissect, retract, and manipulate. The reusable handles are offered in both insulated and noninsulated actuating rings that adapt to various interchangeable jaw configurations with integral shafts. The shaft of the jaws fits into the handle and can be taken apart for cleaning. The jaws are rotated by turning the knob on the handle.
The provided text is a 510(k) summary for the K&W 2-Piece Take-Apart Instruments. It describes the device, its intended use, and claims substantial equivalence to a predicate device. However, it does not contain any information about acceptance criteria, device performance results, study design, sample sizes, ground truth establishment, or expert involvement as requested in the prompt.
Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets them based on the provided text.
The document is primarily focused on establishing substantial equivalence to a predicate device (Karl Storz Endoscopy America, Inc., K952149) based on similar intended use and technological characteristics, rather than presenting a performance study with defined acceptance criteria.
§ 876.1500 Endoscope and accessories.
(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.
