The description focuses on mechanical and pneumatic features for holding medical devices, with no mention of AI or ML.
No
The UniARM is described as a device for holding other medical devices like endoscopes and retractors, serving as a stable platform during surgery. It does not directly provide therapy to a patient.
No
The device is described as a holder for medical devices like endoscopes and retractors during surgery, providing a stable platform. It does not perform any diagnostic functions such as analyzing data, imaging, or providing diagnostic interpretations.
No
The device description clearly states it is a physical device ("balanced device using pneumatic brakes") designed to hold other medical devices, not a software application.
Based on the provided information, the UniARM device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to hold medical devices like endoscopes and retractors during surgery. This is a mechanical function performed on the patient's body or within the surgical field, not on a sample taken from the body.
- Device Description: The description details a mechanical arm with pneumatic brakes for holding instruments. It does not mention any components or processes related to analyzing biological samples.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening based on sample analysis
The UniARM is a surgical accessory designed to assist the surgeon by holding instruments, which is a function performed in vivo (within the living body) during a surgical procedure, not in vitro (in glass or outside the living body) on a sample.

Device Description
Summary: the Mitaka UniARM-device is for use in holding medical devices in surgery such as neuro endoscopes, general endoscopes, and hand held instruments. It is a balanced device using pneumatic brakes that can be released from a single switch near the endoscope or hand held instrument. Often referred to as a third arm it provides a stable platform to hold an endoscope or hand held instrument allowing the surgeon the use of his two arms. The system can be released by the push of one button and fixes with the release of that button. A second button is depressed by the palm as a safety device.
A. Design configuration:
- Brakes Uses fail safe clutches which when activated by Nitrogen pressure from operating a. room source allow the clutches to turn freely. When the nitrogen pressure is released by surgeon controlled button the pressure escapes and the clutches hold tight.
- ت Mechanics - The UniARM uses a system of counterweights that allow the surgeon to balance the weight of an endoscope or instrument. This gounter balancing allows greater ease and precision in repositioning the endoscope or instrument.
- Base The system is mounted to a base with four wheels so it can be positioned at the side of patient. Base brakes hold the base securely. The base has mounted an elevating unit to allow arm to be raised and lowered for optimal positioning.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
- Non-clinical performance data: The system goes through a test procedure using a force gauge to test all brake holding power. The same force measurement system is used on the Point Setter. See section 18.
- Clinical Performance: The system has been tested in operating rooms with patients for over one year in Japan where it is manufactured.
- Conclusion: Clinical, performance, and non-clinical validation compared to Kroner-Wingman and Mitaka Point Setter show that the devices are substantially equivalent to the UniARM. The UniARM merely offers improvements in reach, holding power, and convenience.

§ 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.
