Head-mounted pointing device

A head-mounted pointing device, comprising:

• a frame formed from a circumferential headband and a cross strap that extends between opposite sides of the circumferential headband;
• a battery pack mounted at the center of the cross strap;
• a first laser pointer mounted on a right side of the circumferential headband, the first laser pointer emitting a first color;
• a first pneumatically controlled switch for controlling the laser pointer, the switch including a flexible straw extending from the base of the first laser pointer and is connected to a first pressure transducer, the first switch being configured to sense the difference in pressure between a high port and a low port, and switching between states when a differential pressure above a specified threshold level has been applied for a specified time period;
• a second laser pointer mounted on a left side of the circumferential headband, the second laser pointer emitting a second color different from the color;
• a second pneumatically controlled switch for controlling the second laser pointer, the second switch including a flexible straw that extends from the base of the second laser pointer and is connected to a second pressure transducer, the second switch being configured to sense the difference in pressure between a high port and a low port, and switching between states when a differential pressure above a specified threshold level has been applied for a specified time period;
• means for changing the size of the circumferential headband;
• means for changing the size of the cross strap;
• and
• a mount on a front side of the circumferential headband, the mount having an arm and a grip.

A method of using a head-mounted pointing device to point to a given target during a surgical procedure, comprising:

• donning the head-mounted pointing device;
• toggling on a laser pointer of the pointing device by breathing at a pneumatically controlled switch to generate a differential pressure above a specified threshold level for a specified time period to activate a laser beam;
• and
• pointing the laser beam at the given target;
• wherein the head-mounted pointing device comprises:
• a circumferential headband;
• a cross strap extending between opposite sides of the circumferential headband;
• a battery pack;
• the laser pointer mounted on a right or left side of the circumferential headband;
• and
• the pneumatically controlled switch extending from a base of the laser pointer.
