Inductive powered surgical device with wireless control
A system and method for wirelessly powering an electrosurgical device using a generator to generate a radio frequency (RF) energy field. A switch on the electrosurgical device sends a wireless signal to the generator, where the generator allows a current to pass through an inductive coil to generate the RF energy field. The RF energy field induces a current to flow across an inductive coil within the electrosurgical device. The current flow is then processed through a RF conditioning circuit and outputted to the end effector assembly of the device.
1. A method for wirelessly operating a hand held electrosurgical device, comprising;
selecting a switch on the hand held electrosurgical device;
sending an instruction wirelessly to a generator to generate an RF energy field;
generating the RF energy field;
inducing, by the RF energy field, a current across an inductor within the hand held device that causes an RF signal;
charging a capacitor within the device; and
supplying the RF signal to an end effector assembly to perform a surgical procedure.
2. The method of claim 1 , wherein selecting the switch further comprises selecting a mode of operation for the device.
3. The method of claim 2 , wherein the mode is cut, ablate, coagulate or seal.
4. The method of claim 2 , further comprising:
conditioning the RF signal into the selected mode.
5. The method of claim 4 , wherein the selected mode is seal and the RF signal is conditioned into a pulsed waveform.
6. The method of claim 4 , wherein the selected mode is cut and the RF signal is conditioned into a sinusoidal waveform.
7. The method of claim 1 , wherein the device is a pencil or a forceps.
8. The method of claim 1 , further comprising charging a rechargeable battery within the device.
9. A method for wirelessly operating a hand held electrosurgical device, comprising:
generating an RF energy field;
selecting a switch on the device to select a mode of operation;
inducing, by the RF energy field, a current across an inductor within the device that causes an RF signal;
charging a capacitor within the device;
conditioning the RF signal into the selected mode; and
supplying the conditioned RF signal to an end effector assembly to perform a surgical procedure.
10. The method of claim 9 , wherein the mode is cut, ablate, coagulate or seal.
11. The method of claim 9 , wherein the device is a pencil or a forceps.
12. The method of claim 9 , further comprising charging a rechargeable battery within the device.
