OCS2 Cortical Stimulator

Medical Specialties: Neurology

The Integra OCS2 cortical stimulator is a portable medical device designed for brain mapping during neurosurgical procedures. Battery-powered, this bipolar stimulator delivers a constant current adjustable between 0 and 10 mA, with different pulse durations and frequencies. Thanks to its intuitive interface, LCD control screen and compact design, it enables targeted and reliable stimulation of the cortex, helping to identify essential functional areas. Used exclusively with the OCS2PND probe, it meets the requirements of complex surgical environments in complete safety.



Description

OCS2: Intraoperative Cortical Stimulation: a Reliable Solution for Surgical Teams

The Integra OCS2 cortical stimulator is designed to assist neurosurgeons during functional brain mapping procedures. This device enables the precise identification of critical areas of the cerebral cortex, particularly in the motor and language regions, in order to preserve essential functions during resections.

Battery-powered, the OCS2 is fully portable, making it easy to integrate into a variety of operating environments. It features a compact design (approximately 30 cm x 35 cm x 35 cm) and weighs only 2.3 kg. The device has an LCD screen that displays the current delivered, measured from the baseline to the peak. Two stimulation ranges are available: 0 to 1 mA and 0 to 10 mA, allowing for gradual adjustment according to clinical needs.

The practitioner can adjust the pulse duration between 0.1 and 2 milliseconds and the frequency between 5 and 100 Hz. The volume of the audible signal is also adjustable. An indicator light activates as soon as the device delivers a current, ensuring immediate visual monitoring of the operating status.

The output management has three positions: off, stimulation, and current check (Check Current mode). The latter allows stimulation to be simulated through an internal resistance of 10, 000 ohms to check the settings before application to the patient.

The device is only compatible with the OCS2PND probe, which is designed specifically for this model. This flexible probe, with polished stainless steel spherical tips, ensures precise localisation of the stimulation site. The use of older generation probes is strictly prohibited with the OCS2 model.

Particular attention has been paid to electrical safety: the system complies with IEC and EN 60601 standards and has type BF protection against electric shock. Continuous operation, combined with enhanced electromagnetic compatibility, makes it stable even in the presence of other medical equipment.

The OCS2 cortical stimulator is not intended for any use other than that specified in the instructions. Its improper use or combination with other high-frequency surgical equipment may present risks to the patient or the device.
