Endoscopy equipment maintenance is what keeps a tower reliable on the day of the list, and it costs far less than emergency repairs and cancelled cases. A good plan covers daily user checks, scheduled inspections of each module, electrical safety testing, software and calibration where applicable, and a documented service contract. This guide sets out a practical plan that biomedical engineering and the theatre team can adapt to their own equipment.
Daily and weekly user checks
Most failures are noticed first by the users. Before the first case, power the tower, confirm the picture on the monitor, check the light output, inspect cables and connectors for damage and make sure the insufflator and pump pass their self-tests. Record any alarm or irregularity in a log kept on the tower.
Weekly checks can include wiping vents and dust filters, inspecting castors and brakes on the trolley, checking footswitch cables and examining telescope windows and light-cable ends for damage. Anything unusual is escalated to biomedical engineering. Short, consistent routines catch problems early.
Checks per module
The camera system needs inspection of the camera head, its cable, connectors and seals. ENDOCAM Logic 4K has an autoclavable camera head with a replaceable cable, so a worn cable can be changed without replacing the head. Verify white balance, focus and the function of buttons on the head, and keep presets and user settings backed up as the manufacturer allows.
For the light source, check output and automatic control and note the operating hours of lamp or LED as the manufacturer specifies. For the insufflator, verify flow and pressure behaviour against the specification. For the irrigation pump such as FLUID CONTROL 2225, test irrigation and suction function, the touchscreen, tubing detection and, if fitted, the weighing cells of the optional balancing module for fluid deficit. See also fluid management systems.
Electrical safety and IEC 62353
Electrical safety testing after installation, after repair and at defined intervals is a core part of the plan. IEC 62353 is the standard commonly used for recurrent testing and testing after repair of medical electrical equipment. It covers protective earth resistance, leakage currents and a functional check, depending on the device class and type.
Define the interval with your biomedical engineers, manufacturer recommendations and local requirements. Keep the test results and the instrument used with its calibration certificate. Replace damaged power cords at once and do not use adaptors that bypass the earth connection.
Telescopes, cables and accessories
Telescopes and light cables are the most frequently damaged items. Inspect the telescope for bent shafts, scratched windows and moisture, and test light cables for broken fibres by looking at the transmitted light. Establish a rule that any telescope with fogging inside or a visible defect is withdrawn. See rigid endoscope repair.
Reprocessing quality also affects the equipment life. Residue on light posts or couplers degrades image quality; follow the instructions in our guide to rigid endoscope cleaning. Keep a small stock of spare cables, drapes and telescopes so that one failure does not stop the list.
Service contracts, logs and next steps
A service contract should state the scope (preventive visits, repairs, parts, software updates), the response time, loan equipment, exclusions and who performs the work. Ask where engineers are based and whether they are trained by the manufacturer. Maintain a log per device with serial number, installation date, inspections, faults and repairs; it supports decisions on replacement. For purchase planning see the tender specification guide.
Beckfinity offers installation and maintenance support for the equipment we distribute; see our service pages or contact our specialists to plan a preventive maintenance programme for your endoscopy tower.
Frequently asked questions
How often should an endoscopy tower be serviced?
Follow the manufacturer's recommended interval and your hospital policy, typically at least annually, with daily user checks in between.
What is IEC 62353?
A standard for recurrent testing and testing after repair of medical electrical equipment, covering electrical safety checks such as earth resistance and leakage current.
What should a service contract include?
Scope of visits, repairs and parts, response times, loan equipment, exclusions, software updates and the qualifications of the engineers.
Who should do the daily checks?
Theatre staff using a short checklist, with problems escalated to biomedical engineering.
