HS HAAG-STREIT SURGICAL / MÖLLER-WEDEL Hi-R Surgical Microscope Analysis Report

Device Identification

The product in the examined images is an advanced surgical operating microscope used in medical and surgical operations. The device is an integrated system consisting of a mobile floor stand, articulated arms, an optical head unit, a touch control screen, and a light source/power unit.

Brand and Model Information

The following brand and model identifiers were detected during detailed visual inspections of the product:

• Optical Head Brand/Model: The microscope head part of the product clearly displays the MÖLLER Hi-R logo and inscription. Additionally, a MÖLLER-WEDEL INTERNATIONAL label is present on the head.
• Power and Light Source Unit: The HS HAAG-STREIT SURGICAL logo and brand are clearly visible on the power unit integrated into the device’s body.

Based on this information, the device is a Hi-R series surgical microscope incorporating Möller-Wedel technology within Haag-Streit Surgical.

Originality and Label Information

Upon examining the logos, labeling standards, and component quality on the product, it is assessed to be an original MÖLLER-WEDEL / HAAG-STREIT equipment. The label information on the optical head includes the following details:

• REF (Reference Number): 658 935
• SN (Serial Number): 4209

Areas of Use

This device is designed for use in microsurgical operations requiring high precision and magnification. The “branch” option in the touch screen menu indicates that the device can be adapted for multiple disciplines (such as Ophthalmology – Eye diseases, Neurosurgery – Brain surgery, or ENT). Its precise optical structure and illumination system particularly provide detailed imaging in operating room environments.

General Condition and Physical State

The device generally appears to be assembled, with all its parts together, and electrically operational. However, there are some notable details regarding its casing and hygiene:

Physical Deformation and Damage Detection

• Casing Crack: Immediately below the plastic body containing the control screen, there is a distinct vertical crack (image 6). This indicates that the body has suffered an impact or that the plastic has experienced fatigue over time.
• Cosmetic Condition: Friction marks and discoloration due to use have been observed on the device’s blue base plate and wheel covers.
• Cleaning Requirement: Dust accumulation and cobweb-like structures are visible in the ventilation grilles of the light source unit (image 7). This condition indicates that the device’s ventilation system requires maintenance.

Mechanical and Electronic Component Analysis

• Electronic Control Panel: The integrated touch screen is operational (image 6). Screen brightness is adequate, and the Turkish language option is active in the menu. The menu displays options such as Brightness, Microscope, User, Settings, Branch, and Balance. Additionally, information such as “display” in the bottom bar, “5.4x” as magnification ratio, and “253 mm” as working distance/focus can be read.
• Light Source: The device’s illumination system is active and operational. Image 8 clearly shows a powerful and focused beam of light cast onto a hand. Furthermore, the green “STATUS” LED on the power unit is illuminated.
• Mechanical Arms: Visually, no missing components (screws, covers, etc.) have been detected in the device’s head and arm structure. The balance and braking buttons on the arm are in place.
• Wheels: The lower stand has a wheeled structure, and its braking mechanisms (yellow pedals) are visible on it.

Accessories and Connections

• The device has two handgrips on the right and left sides, equipped with functional joysticks/buttons, for the surgeon’s use during operation.
• Binocular (double-eyed) viewing tubes are attached to the optical head.
• The necessary power cables are present on the device.
• Extra accessories such as an external foot pedal, additional monitor, or spare bulb box are not visible in the images.

Quantity Information

The images show 1 (one) unit of a surgical microscope in an integrated system.

Potential Failure Risk and Assessment

The device powers on electrically, and the screen and light system operate without issues; this proves that the basic functions of the electronic components are sound. However, the crack below the screen could expand over time, compromising the casing’s integrity or allowing dust/liquid ingress. Additionally, the dirt in the ventilation grilles of the power unit indicates that the device requires fan cleaning and filter maintenance; otherwise, there is a risk of overheating. Apart from this, although optical clarity can only be determined by physical testing, no breaks or cracks are visible in the lenses based on external appearance.
