Multi-pedal footswitch/joystick selected for ophthalmic surgery microscope

Herga Technology : 21 September, 2014  (Application Story)
As an important part of its switching and sensing products range, Herga Technology designs and supplies hand and foot controls for medical equipment applications. One such application example is the 8-way footswitch/joystick controller supplied to the global medical and optical equipment manufacturer, Leica Microsystems, as an innovative option for its M220 F12 routine ophthalmic surgery microscope.
Multi-pedal footswitch/joystick selected for ophthalmic surgery microscope

The M220 F12 microscope provides high quality optics at reasonable cost and is the entry level model of a modular range that offers ophthalmic surgeons the enabling technology to perform very complex eye operations. A version of the M220 F12 that includes the Herga footswitch/joystick is in wide use in India as part of a large-scale government programme for low-cost cataract surgery. The programme, which is conducted throughout the country by mobile specialist teams that travel to remote rural areas, aims to provide this blindness reversing procedure for hundreds of thousands of individuals each year.


 


Whilst cost considerations are important factors, the patient throughput and success rate is critical - and for such work the speed and quality of each operation relies upon an excellent microscope system. The operation throughput rate is also optimised with the use of the Herga-designed electric footswitch/joystick which includes an integral joystick that is actually operated by the surgeon adjusting the X and Y positions of the microscope by gripping the joystick between his toes. This cost and time effective one-man operation involves remotely focussing and fine positioning the microscope over the patient’s eye by jogging each axis into position with a combination of push switches and ‘on-off’ joystick switches for each direction. The footswitch/joystick design also includes small raised area to support the surgeon’s heel whilst he operates the joystick.


 


The low profile and fully sealed IPx8 footswitch/joystick is able to withstand the rigours of portable use in the harsh weather extremes found throughout Asia as well as provide the consistent sensitivity required for the ophthalmic surgeon. To ensure the IEC/UL 60601 quality specified for this demanding application, each unit is fully encapsulated after rigorous electrical testing and individually pressure tested before despatch.


 


Herga won the contract to supply the footswitch against stiff international competition following initiatives by Leica to drive down the costs of its product for the Indian and Asian markets.


 


The diverse requirements for this demanding industry calls for single and multi-pedal switch controls that cover contact and non-contact electric switching as well as pressure and vacuum switching technologies. For many medical applications areas, Herga is able to call upon its IEC/UL 60601 approval status to supply "standard" products - these options extend to switching/sensing parameters, number of switches, mechanical and electrical interfacing, colours, logos etc. When standard products are not adaptable, Herga provides a custom design service.
