Regulatory Classification

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.

Special Controls

*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.

### Description:

The Kronner Low Profile Scope Holder consists of mechanical linkages that connect between the operating table side rail and the shaft or head of a rigid endoscope. A telescoping arm distinguishes the device from other endoscope holders. Inert nitrogen gas at 100-150 psi is used to provide the energy to multiple joints to lock the holder in position when a control button is released by the operator.

# Intended Usage:

The Kronner Low Profile Scope Holder is used to hold rigid endoscopes during endoscopic surgery and to allow rapid position changes by the pressing of a control button by the operator.

{6}------------------------------------------------

# Summary of technological characteristics of device compared to predicate devices.

The Kronner Low Profile Scope Holder is essentially equivalent to the Leonard Arm, except that it has a telescoping arm instead of an arm with a hinge joint, and uses nitrogen gas pressure as an energy source to hold position rather than vacuum.

The Kronner Low Profile Scope Holder uses flexible lines and a control which can be attached to the camera to supply and control the energy used to lock the joints. These features are built into the Leonard Arm.
