Detailed Analysis Report of Leica M841 Surgical Operating Microscope

Device Identification and Description

The device shown in the visuals is an advanced surgical operating microscope used in medical procedures, especially in microsurgical operations (sensitive branches such as ophthalmology, neurosurgery, or ENT). The product consists of an articulated arm system and an optical head unit mounted on a mobile wheeled base (floor stand).

Brand and Model Information

Upon examining the text and logos on the visuals, the brand and model of the device have been identified with unmistakable clarity:

• Brand: Leica
• Model: M841

This identification is based on the black-colored “LEICA M841” text located on the side of the optical head unit and the red “Leica” logos found on the device’s arm, control unit, and optical body.

Originality Assessment

The font of the logos on the device, their placement, the shade of “Leica” red, material quality, and craftsmanship details (joint connections, paint quality) indicate that the product is a 100% original Leica production. There are no indications of it being an aftermarket or replica product.

Areas of Use

This device is used during surgical operations to enable the surgeon to see the operating field in more detail by magnifying it. Known for their optical quality and precision, these systems are designed for use in hospital operating theaters.

Quantity Information

A total of 1 unit of the integrated surgical microscope system (including base, stand, arms, and optical head) is present in the visuals.

Overall Condition and Physical State

The overall appearance of the device is used but well-preserved (clean second-hand). No significant damage is visible on the device.

• Physical Deformation: No dents, deep scratches, cracks, or breakages have been detected on the metal stand and arms or plastic coatings. Its paint has generally maintained its whiteness, and no severe corrosion signs such as yellowing or rust are observed.
• Cleanliness: While the device appears quite clean, there might be slight signs of use or dust accumulation on the black sections of the base, but this is not an operational fault.

Mechanical Component Examination

The device’s movable mechanisms appear visually sound.

• Arms and Joints: The articulated arms, which allow the microscope to be positioned, are in place and sturdy. Screws and covers at the connection points appear complete.
• Base and Wheels: The device’s heavy base stand and the wheel structure enabling its movement are intact. The fastening (brake) mechanisms on the base are visually present.
• Adjustment Knobs: The manual adjustment knobs (black colored) on the optical head and binocular parts are present and sturdy.

Electronic Components and Screen Analysis

• Control Unit: A white electronic control box is mounted on the central body of the stand. This box features a “Leica” logo, an LCD screen, and membrane-type control buttons (up/down arrows and menu buttons).
• Screen Status: Since the device is turned off, there is no visual data regarding the operational status of the screen; however, no cracks or breakages are visible on the screen panel.
• Cabling: Power and data cables are visible hanging from the back of the device. No visible breaks or compressions have been noticed in the outer insulation of the cables.
• Foot Switch: In the visuals (especially images 1, 5, and 6), a foot control unit platform integrated into the device is visible on the base. However, an external wired pedal unit is not distinctly visible in the visuals; the integrated area on the base might be reserved for pedal placement, or the control unit is coupled to this section.

Optical Components and Accessories

• Binocular Tubes: The device includes two sets of observation binoculars (binocular tubes). This indicates that the device can be used simultaneously by both a surgeon and an assistant. No significant damage is visible on the lens covers or glass of the optical tubes.
• Objective Lens: The objective lens located at the very bottom of the optical head bears the inscription “WD = 200mm“. This indicates that the working distance of the device is 200 millimeters.
• Eyepieces: The rubber parts of the oculars are in place and do not appear worn.

Technical Labels and Inscriptions

Technical details readable in the visuals are as follows:

• Model Name: LEICA M841
• Brand Logos: Leica (At various points)
• Lens Information: WD – 200mm
• Graduation (angle and adjustment) markings are present on the optics.
• Serial Number / Year of Manufacture: While small labels are visible on the device, text indicating the serial number or year of manufacture cannot be read due to the camera’s distance.

Current Faults and Potential Risk Analysis

As a result of visual inspection, no obvious evidence of malfunction (e.g., breakage, severed cable, error message) that would prevent the device from operating has been detected. As potential risks, non-visual factors such as dust accumulation inside the lenses or electronic board lifespan should be considered, given that it is a second-hand optical device. However, based on its external appearance, the device gives the impression of being ready for immediate use or having been maintained. On-site inspection of cable entries and optical head movement capability is recommended.
