## Abstract

An interchangeable tip comprising: a stylet; a blade module including: an enclosure that electrically connects, signally connects, or both the interchangeable tip to a power source, a signal source, or both; and blade circuitry having: one or more control buttons, one or more switches, or both for controlling operation one or more functions of the interchangeable tip.

## Claims

### Claim 1

1) An interchangeable tip comprising:
a. a stylet;
b. a blade module including:
i. an enclosure that electrically connects, signally connects, or both the interchangeable tip to a power source, a signal source, or both; and
ii. blade circuitry having:
1. one or more switches for controlling operation one or more functions of the interchangeable tip.

### Claim 2 (depends on 1)

2) The interchangeable tip of claim 1, wherein the blade circuitry includes an identification circuit that provides a signal that is monitored by a controller, a control module, a generator, or a combination thereof.

### Claim 3 (depends on 1)

3) The interchangeable tip of claim 1, wherein the blade circuitry includes an identification circuit having one or more capacitors that generate a capacitance that is monitored by a controller, a control module, a generator, or a combination thereof.

### Claim 4 (depends on 1)

4) The interchangeable tip of claim 1, wherein the enclosure includes an enclosure connector for connecting the interchangeable tip to a handpiece of a debrider so that power is provided from the handpiece to the interchangeable tip.

### Claim 5 (depends on 1)

5) The interchangeable tip of claim 1, wherein the blade circuitry includes a control circuit that controls one or more functions of the interchangeable tip.

### Claim 6 (depends on 5)

6) The interchangeable tip of claim 5, wherein the one or more switches are part of the control circuit and the one or more activate one or more functions when actuated.

### Claim 7 (depends on 6)

7) The interchangeable tip of claim 6, wherein the one or more functions are a monopolar energy source, a bipolar energy source, forward rotation, reverse rotation, oscillating rotation, reciprocating, or a combination thereof.

### Claim 8 (depends on 5)

8) The interchangeable tip of claim 5, wherein the control circuit includes a capacitor so that the monopolar energy source, the bipolar energy source, or both are prevented from being activated through the stylet if the one or more control buttons, the one or more switches, or both are not activated and a short is present in the control circuit.

### Claim 9 (depends on 1)

9) The interchangeable tip of claim 1, wherein the stylet includes an outer tube and an inner tube disposed in the inner tube, and
wherein the one or more pins are in electrical communication with the outer tube and the one or more pins are configured so that the outer tube rotates during use and maintains the electrical communication.

### Claim 10 (depends on 1)

10) The interchangeable tip of claim 1, wherein the one or more control buttons, switches or both controls an application of power to the stylet by turning a power supply on and off.

### Claim 11

11) An interchangeable tip comprising:
a. a stylet;
b. a blade module including:
i. an enclosure that electrically connects, signally connects, or both the interchangeable tip to power source, a signal source, or both; and
ii. blade circuitry including an identification circuit;
wherein the blade circuitry provides a signal to a controller, control module, generator, or a combination thereof so that the controller, the control module, the generator, or a combination thereof determines one or more functions of the interchangeable tip, and
wherein the stylet is free of contact with electrodes so that the stylet is free of power.

### Claim 12 (depends on 11)

12) The interchangeable tip of claim 11, wherein the blade circuitry is free of a control circuit for controlling the one or more functions of the interchangeable tip.

### Claim 13 (depends on 11)

13) The interchangeable tip of claim 11, wherein the interchangeable tip is free of an energy source that can be applied through the stylet.

### Claim 14 (depends on 11)

### Claim 15 (depends on 14)

15) The interchangeable tip of claim 14, wherein the signal provided by the blade circuitry is a capacitance of the one or more capacitors in the blade circuitry.

### Claim 16 (depends on 11)

16) The interchangeable tip of claim 11, wherein the enclosure includes a connection enclosure that connects the interchangeable tip to a handpiece.

### Claim 17

17) An interchangeable tip comprising:
a. a stylet;
b. a blade module including:
i. a connection enclosure and
ii. a control enclosure including two or more pins;
wherein a signal across the two or more pins have a capacitance of zero.

### Claim 18 (depends on 17)

18) The interchangeable tip of claim 17, wherein the connection enclosure is free of any spring pins for providing electrical power to the stylet.

### Claim 19 (depends on 17)

19) The interchangeable tip of claim 17, wherein the blade module is free of a printed circuit board.

### Claim 20 (depends on 1)

20) A method comprising:
a. inserting an interchangeable tip of claim 1 into a handpiece;
b. providing a signal to the handpiece and the interchangeable tip; and
c. detecting a capacitance generated by the interchangeable tip in response to the step of providing the signal;
wherein the step of detecting determines whether the interchangeable tip is configured to provide bipolar energy, monopolar energy, no power, or a combination thereof.
