Lateral Drive System for Treatment Couches

Product Specifications

Technical details and manufacturing context for Lateral Drive System

Definition

The Lateral Drive System is a critical component of a medical treatment couch that provides controlled horizontal movement along the lateral axis. It allows precise positioning of the patient during medical procedures, ensuring accurate alignment with imaging or treatment equipment. This system is essential for radiotherapy, diagnostic imaging, and surgical applications where millimeter-level positioning accuracy is required. The system typically uses electric motors, lead screws or ball screws, and linear guides to convert rotational motion into precise linear movement. A control system manages the motor operation, allowing smooth acceleration, deceleration, and positioning with feedback from encoders or sensors to ensure accuracy. The drive unit is constructed from materials such as aluminum alloy, stainless steel, and engineering plastics, offering a balance of strength, corrosion resistance, and weight reduction. Key parameters include a maximum load capacity of 150–250 kg (including patient and couch top weight), a lateral travel range of 200–400 mm, positioning accuracy of ±0.1–±0.5 mm (repeatability under load, per ISO 9283), and a maximum lateral speed of 20–50 mm/s. The drive motor power ranges from 0.2–0.75 kW (per IEC 60034), with a supply voltage of 24 V DC ±10%. The operating temperature range is 10–40 °C, and the ingress protection rating is IP54–IP65 (per IEC 60529). The drive unit weight is 15–30 kg (excluding mounting brackets), and the noise level is ≤50 dB(A) at 1 m distance under load (per ISO 3746). These values are reference ranges and must be verified with the legal manufacturer for the specific model and application. The system is designed for integration into treatment couches, and its performance should be confirmed through proper testing and documentation.

Working Principle

The Lateral Drive System converts rotational motion from an electric motor into precise linear movement using lead screws or ball screws and linear guides. A control system regulates the motor's speed and position, using feedback from encoders or sensors to achieve accurate positioning. The system ensures smooth acceleration and deceleration, allowing controlled lateral movement of the treatment couch. The mechanical components are housed in a drive unit that is mounted to the couch frame, and the system operates within specified load, speed, and environmental conditions.

Frequently Asked Questions

What is the typical load capacity of the Lateral Drive System?

The maximum load capacity is 150–250 kg, including the patient and couch top weight. This is a reference range; the exact capacity depends on the specific model and configuration, so it must be confirmed with the manufacturer.

What positioning accuracy can be expected?

The positioning accuracy is ±0.1–±0.5 mm, measured as repeatability under load, according to ISO 9283. Actual accuracy may vary with installation and usage conditions, so verification with the manufacturer is recommended.

What are the electrical requirements?

The drive motor power is 0.2–0.75 kW (per IEC 60034), and the supply voltage is 24 V DC ±10%. Other voltages may be available on request, but this must be confirmed with the supplier.

What environmental conditions can the system operate in?

The operating temperature range is 10–40 °C, and the ingress protection rating is IP54–IP65 (per IEC 60529). For harsher environments, higher IP ratings may be optional, but this should be verified with the manufacturer.
