Abstract

A device for applying a medical element has a housing defining a longitudinal axis with a channel disposed therethrough. The housing has a proximal and a distal opening. The device also has at least one sensing device positioned adjacent to the distal opening. The device also has a signaling device disposed adjacent the housing. The at least one sensing device interrogates a bone location for one or more variables of the bone location as the device is moved over the bone location. The at least one sensing devices outputs a signal to the device and the signaling device signals an identification of a homogenous bone region. The medical element is applied to the homogenous bone location coaxially from the proximal opening through the channel and through the distal opening without removal of the device from the homogenous bone region.

Claims

1. A device for applying a medical element comprising:

a housing defining a longitudinal axis having a channel being disposed therethrough, said housing having a proximal and a distal opening;

at least one sensing device mounted to the housing adjacent said distal opening thereof;

a signaling device mounted in said housing, the signaling device including a controller operatively connected to control the sensing device; and

an alarm mounted in said housing, operatively connected to be controlled by the controller;

wherein said at least one sensing device is configured and adapted to interrogate an external surface of a bone location for one or more variables of the cortical and cancellous bone of the bone location as the at least one sensing device is moved over the external surface of the bone location;

wherein said at least one sensing device is configured and adapted to generate a signal based upon the one or more variables of the cortical and cancellous bone of the bone location when positioned along the external surface of the bone location;

wherein said at least one sensing device is configured and adapted to output the signal to the signaling device;

wherein said signaling device is configured and adapted to provide an identification of a homogenous bone region and to activate and deactivate the alarm accordingly; and

wherein the channel of the housing is configured and adapted so that a medical element can be applied to the homogenous bone location coaxially from said proximal opening through said channel and through said distal opening without removal of the device from the homogenous bone region wherein said at least one sensing device includes a plurality of ultrasonic transducer elements disposed around said distal opening.

2. The device of claim 1, wherein said housing is cylindrical.

3. The device of claim 1, wherein said alarm is disposed on an outer surface of said housing.

4. The device of claim 1, wherein said alarm is configured and adapted to emit an audible alarm.

5. The device of claim 1, wherein said alarm is configured and adapted to emit a visual alarm.

6. The device of claim 1, wherein said one or more variables of the bone location are selected from the group consisting of bone mineral density data, bone thickness data, bone histology data, bone disease data, bone degeneration data, bone water content data, bone blood content data, bone marrow content data, bone cartilage composition data, and any combinations thereof.

7. The device of claim 1, wherein the channel of the housing is configured and adapted so that the medical element can be applied to the homogenous bone region coaxially from said proximal opening through said channel and through said distal opening without removal of the device from the homogenous bone region to form a pedicular channel.

8. The device of claim 7, wherein the channel of the housing is configured and adapted to accommodate a medical element that is a drill bit.

9. The device of claim 1, further comprising a filter coupled to said at least one sensing device for removing noise from said signal.

10. The device of claim 1, wherein the alarm includes a vibration device for providing a tactile indication that said homogenous location has been determined.

11. The device of claim 1, further comprising a plurality of sensing devices positioned adjacent said distal opening.

12. The device of claim 1, wherein the channel of the housing is configured and adapted to accommodate a medical element that is a Kirschner wire.

13. A device for applying a medical element comprising:

a housing defining a longitudinal axis having a channel being disposed therethrough, said housing having a proximal and a distal opening;

at least one sensing device mounted to the housing adjacent said distal opening thereof;

a signaling device mounted in said housing, the signaling device including a controller operatively connected to control the sensing device; and

an alarm mounted in said housing, operatively connected to be controlled by the controller;

wherein said at least one sensing device is configured and adapted to interrogate an external surface of a bone location for one or more variables of the cortical and cancellous bone of the bone location as the at least one sensing device is moved over the external surface of the bone location;

wherein said at least one sensing device is configured and adapted to generate a signal based upon the one or more variables of the cortical and cancellous bone of the bone location when positioned along the external surface of the bone location;

wherein said at least one sensing device is configured and adapted to output the signal to said signaling device;
