Abstract
Electrical apparatus includes a probe, having a proximal end and a distal end. The probe includes a sensor, which outputs a sensor signal, and a first connector at the proximal end of the probe, electrically coupled at least to the sensor. A probe adapter includes a second connector, which is arranged to mate with the first connector, and a third connector, for coupling to a console. A shield includes a material of high magnetic permeability, which is configured to enclose an internal volume containing the first and second connectors when the probe is connected to the probe adapter.
Claims12
Electrical apparatus, comprising:
- a probe, having a proximal end and a distal end, the probe comprising:
- a sensor, which outputs a sensor signal;
- and
- a first connector at the proximal end of the probe, electrically coupled at least to the sensor;
- a probe adapter, comprising:
- a second connector at a distal end of the probe adapter, which is arranged to mate with the first connector of the probe;
- and
- a third connector located proximal from the first connector and the second connector, and coupled to a console;
- and
- a shield, comprising a mu-metal material of high magnetic permeability, the shield being made of unitary tubular form which is configured to enclose an internal volume containing the first connector and second connectors when the probe is connected to the probe adapter, the unitary tubular form of the shield preventing leakage of electromagnetic fields from the first connector and the second connector when the probe is connected to the probe adapter.
A method for producing an electrical device, comprising:
- providing a probe, having a proximal end and a distal end, which comprises a sensor, which outputs a sensor signal, and a first connector at the proximal end of the probe, electrically coupled at least to the sensor;
- providing a second connector, for use in a probe adapter to mate with the first connector of the probe;
- coupling a third connector located proximal of the second connector to connect the probe adapter to a console;
- and
- configuring a shield, comprising a mu-metal material of high magnetic permeability and being made of unitary tubular form, so as to enclose an internal volume containing the first connector and the second connector& when the probe is connected to the probe adapter, the unitary tubular form of the shield preventing leakage of electromagnetic fields from the first connector and the second connector when the probe is connected to the probe adapter.
