Fuente: Wipo "Sensorization" Surgical instrument electronic subsystem 7006 comprising a short circuit protection circuit 7012 for sensors and/or electronic components 7005. A main power supply circuit 7010 is connected to a primary circuit comprising a microprocessor and other electronic components 7008. The main power supply circuit 7010 is also connected to a short circuit protection circuit 7012. The short circuit protection circuit 7012 is coupled to a supplementary power supply circuit 7014, which supplies power to the sensors and/or electronic components 7005 via the electrical conductors 7002, 7004. To reduce damage to the processor 7008 connected to the main power supply terminals 7018, 7020, during a short circuit between the electrical conductors 7002, 7004 of the power supply terminals feeding the sensors and/or electronic components 7005, a self isolating/restoring short circuit protection circuit 7012 is provided.
