Laser Interlock Systems for Hospital Operating Theatres

Illuminated Signs

This system is based upon the market leading ICS-1 laser interlock control panel, which has been installed in many hundreds of locations across the UK and beyond. Lasermet has a long track record in the field of laser interlocks and has been manufacturing and installing these systems since 1996.

When installing in Operating Theatres we use a configuration designed especially to address the particular needs of Surgeons and other theatre staff. This configuration we call a 'locking interlock system' (explained here).

As well as performing interlock functions the system will automatically switch the illuminated laser warning signs.

Requirement for Interlocks

The Department of Health document entitled ‘The Guidance on the Safe Use of Lasers in Medical & Dental Practice’ states that interlocks are indicated where the laser beam may exceed the MPE at the entrance to the room.  This applies to many if not most lasers used in operating theatre practice. Additionally the document adopted by the UK as the Laser Safety User Guide (IEC TR 60825-14 ‘Safety of Laser Products Part 14 – A Users Guide) states that interlocks should be used for all Class 3B and Class 4 lasers unless a risk assessment can show that they are not necessary.

Objections

Traditionally, interlocks have been unpopular in hospitals as they can disable the laser at the time when the surgeon wants to use it. Lasermet have addressed this problem by designing a laser interlock system which both protects the staff and protects the integrity of the operation by preventing interruptions to the laser. This is achieved by the use of maglocks on the doors which are powered up whenever the laser is enabled, so preventing casual opening of doors. Authorised override by the use of a keypad code enables suitably prepared staff to still enter or leave the theatre without interruption to the laser. This system has been installed in many operating theatres enabling lasers to be used uninterrupted and without risk to staff.
