66 Vision YZ20P5 Surgical Microscope Analysis Report

Device Identification

The device shown in the visuals is a surgical microscope (Operation Microscope) used in medical surgical procedures, equipped with a wheeled and portable stand. The device consists of a mobile floor stand, a vertical support column, a horizontal arm containing the power and control box, an articulated (movable) microscope arm, and a binocular (double-eyed) microscope head.

Brand and Model

Upon examining the labels and logos on the device, the brand and model information has been definitively identified as follows:

• Brand: 66 Vision (Manufacturer: Suzhou 66 Vision Tech Co., Ltd.) – The company’s “eye-shaped” logo and its Chinese/English trade name are clearly visible on the device’s power box.
• Model: YZ20P5 – The model code “YZ20P5” followed by the Chinese phrase “Surgical Microscope” is clearly readable on the power box.

Areas of Use

This device, by its “YZ20P5 Operation Microscope” model definition, is used in medical surgical procedures. It allows the surgeon to view the operation area magnified, especially in microsurgical interventions requiring detailed vision, primarily in ophthalmology (eye surgery). Thanks to its portable design, it can be easily transferred to different locations in operating rooms or examination rooms.

Authenticity Status

Upon examination of the brand logos, model print quality, paint finish, and industrial design (cast parts, original knobs) on the device, the product is assessed as Original. No indications of aftermarket modifications or “assembled” parts are observed.

General Condition and Cosmetic State

The device appears to be second-hand and used in terms of its general appearance. However, its structural integrity has been preserved. Its general condition can be detailed as follows:

• Physical Deformation: No deep dents, cracks, or breaks have been detected on metal and plastic components. However, slight dulling and very minor signs of use (hairline scratches) may be present on metal connection points and painted surfaces due to aging.
• Cleanliness: The device generally appears clean, but there is a possibility of slight dust accumulation in the lens areas or joints. No significant dirt or rust has been observed.

Mechanical and Movable Components

The analysis of the mechanical parts providing the microscope’s mobility is as follows:

• Articulated Arm: The pantograph arm system supporting the microscope head appears sturdy. The spring mechanism is housed within a closed casing.
• Wheels: There are 4 wheels located under the mobile stand. The wheels appear to be in place.
• Adjustment Knobs: The black fixation and adjustment knobs on the microscope head are complete and appear physically sound.

Electronic Components and Control Unit

Visual analysis regarding the power unit and illumination system:

• Control Box: On the white main unit, there is a green illuminated On/Off switch, fuse slots, and a potentiometer knob, presumed to be for illumination brightness adjustment.
• Cabling: A blue cable (likely a fiber optic light or power cable) extends from the control box to the microscope head. Additionally, black power and data cables are visible. No visual breaks or severe crimps have been detected on the outer surfaces of the cables. The markings “CHANG 300/300V” are readable on the cable, indicating its insulation standard.

Optical Head and Lenses

The microscope head, being the most critical part of the device, is in place:

• Binocular Tube: Dual eyepieces (oculars) are present. The rubber eye guards are in place.
• Objective: The main objective lens at the bottom is attached.
• Sterilization Caps: Black caps, used for surgical sterility, are present over the focus and magnification adjustment knobs.

Accessories and Missing Parts Check

The accessories provided with the device in the visuals are as follows:

• Foot Pedal (Footswitch): A black, dual-button foot pedal is present at the base of the stand. This pedal typically allows the surgeon to perform motorized focusing without using their hands.
• Power Cable: The device’s power cable is present.

Risk of Deficiency: The device’s original dust cover is not present in the visuals. Box contents such as a spare bulb or user manual are not visible in the image.

Label Information

The label and prints on the side surface of the device’s control box contain the following information:

• Logo: Blue eye symbol with “六六” (66) written underneath.
• Product Name: YZ20P5 手术显微镜 (Surgical Microscope).
• Manufacturer: 苏州六六视觉科技股份有限公司 (Suzhou 66 Vision Tech Co., Ltd.).
• Fuse Ratings:
  • 220V: T1.25A 250V
  • 110V: T2.5A 125V
• Other Codes: The serial number (S/N) could not be clearly read from the visual angle; it is usually located on the device’s rear label.

Potential Malfunction Risk

Based on visual inspection, there is no “visible” evidence of malfunction (broken parts, severed cables, burn marks, etc.) on the device. However, issues like fungal growth on lenses or the light source (bulb) having reached the end of its life, which can occur in optical devices, cannot be determined by external examination. The possibility of mechanical balance springs becoming stretched over time should also be considered. Given its clean and well-maintained general condition, the device has a high probability of being in working order.

Quantity Information

The visuals show 1 unit of a complete microscope (including stand, arm, head, and power unit) and 1 unit of a connected foot pedal.
