Surgical hair clippers and vacuum apparatuses including sensing and feedback devices
A surgical hair clipper includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A touch sensor is exposed at the guide surface for contact with the skin area during use. A processor receives a signal from the touch sensor when the touch sensor contacts the skin area. The processor uses logic saved in a memory to instruct a feedback device to provide an indication of skin contact between the touch sensor and the skin area.
1. A surgical hair clipper comprising:
a clipper body;
a blade assembly configured to removably connect to the clipper body, the blade assembly comprising a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade, the blade housing having a guide surface that faces the skin area during a hair removal process;
a touch sensor arranged and configured to be exposed through an opening through the guide surface for contact with the skin area during use; and
a processor that receives a signal from the touch sensor when the touch sensor contacts the skin area, wherein the processor instructs a feedback device comprising a light to provide an indication of skin contact between the touch sensor and the skin area based on the signal;
wherein the clipper body is configured to retain the touch sensor with the blade assembly removed from the clipper body, the opening through the guide surface arranged and configured to align with the touch sensor such that the touch sensor extends at least partially through the opening with the blade assembly removably connected to the clipper body.
2. The surgical hair clipper of claim 1 , wherein the touch sensor comprises a capacitance sensor.
3. The surgical hair clipper of claim 1 , wherein the touch sensor provides a signal to the processor that is indicative of pressure against the skin area.
4. The surgical hair clipper of claim 1 , wherein the touch sensor is connected directly to the clipper body.
5. The surgical hair clipper of claim 4 , wherein the touch sensor has a height to extend at least partially through the opening through the guide surface.
6. The surgical hair clipper of claim 1 , wherein the touch sensor is a first touch sensor, the surgical hair clipper further comprising a a second touch sensor exposed at the guide surface for contact with the skin area during use.
7. The surgical hair clipper of claim 6 , wherein the processor receives a signal from the first and second touch sensors when the first and second touch sensors contact the skin area, wherein the processor uses logic saved in a memory to instruct the feedback device to provide the indication of skin contact between the first and second touch sensors and the skin area.
8. The surgical hair clipper of claim 7 , wherein the processor uses logic saved in memory to instruct a light to illuminate to provide an indication of lack of skin contact between at least one of the first and second touch sensors and the skin area.
9. A method of using a surgical hair clipper, the method comprising:
contacting a skin area with a guide surface of the surgical hair clipper, the surgical hair clipper comprising:
a clipper body;
a blade assembly configured to removably connect to the clipper body, the blade assembly comprising a moveable blade configured to reciprocate to remove hair from the skin area and a blade housing that houses the moveable blade, the blade housing having a guide surface that faces the skin area during a hair removal process;
a touch sensor arranged and configured to be exposed through an opening through the guide surface for contact with the skin area; and
a processor that receives a signal from the touch sensor when the touch sensor contacts the skin area, wherein the processor instructs a feedback device comprising a light to provide an indication of skin contact between the touch sensor and the skin area based on the signal;
wherein the clipper body is configured to retain the touch sensor with the blade assembly removed from the clipper body, the opening through the guide surface arranged and configured to align with the touch sensor such that the touch sensor extends at least partially through the opening with the blade assembly removably connected to the clipper body; and
the processor instructing the feedback device to provide the indication of skin contact between the touch sensor and the skin area based on a signal from the touch sensor.
10. The method of claim 9 , wherein the touch sensor comprises a capacitance sensor.
11. The method of claim 9 further comprising providing a signal to the processor that is indicative of pressure against the skin area using the touch sensor.
12. The method of claim 9 , wherein the touch sensor is connected directly to the clipper body.
13. The method of claim 12 , wherein the touch sensor has a height to extend at least partially through the opening through the guide surface.
14. The method of claim 9 , wherein the touch sensor is a first touch sensor, the surgical hair clipper further comprising a second touch sensor exposed at the guide surface for contact with the skin area during use.
15. The method of claim 14 , wherein the processor receives a signal from the first and second touch sensors when the first and second touch sensors contact the skin area, wherein the processor uses logic saved in a memory to instruct the feedback device to provide the indication of skin contact between the first and second touch sensors and the skin area.
16. The method of claim 15 , wherein the processor uses logic saved in memory to instruct a light to illuminate to provide an indication of lack of skin contact between at least one of the first and second touch sensors and the skin area.
