The present invention relates to a device with an ultrasonic-based probe for drilling and coring. The invention uses ultrasonic and subsonic vibrations produced by a frequency compensation coupler or free mass to produce the hammering action of a partially disengaged probe, with a relatively low axial force required. The invention can also be fitted with irrigation and aspiration capabilities. The invention can furthermore be furnished with a body sensor-feedback apparatus, which provides feedback to the operator as to the optimal frequency and power use of the generator. One embodiment of the invention also has a cooling mechanism to keep the drill or coring apparatus at an optimum temperature.

Floating probe for ultrasonic transducers

Apparatus for probing, sensing, testing penetrating and sampling a medium generally includes an actuator () for generating vibrations at ultrasonic frequencies and a horn () coupled to the actuator () for amplifying the actuator vibrations along with a non-rotating coring and drilling bit () for penetrating the medium. A bit () includes a drill stem () attached to the horn () and a bore () extends through the bit (), horn () and actuator () for withdrawal of samples. A free mass () is disposed between the horn () and the drill stem () for oscillating therebetween in response to the actuator vibration for causing migration of medium debris around and through the actuator bore for effectively self-cleaning of the bit (). The hammering action of the free mass () is used for penetration of the medium and for analysis of the medium though the use of spaced apart accelerometers (and).

Smart-ultrasonic/sonic driller/corer

The present invention relates to a novel device with an ultrasonic based drill and corer. The invention uses ultrasonic and subsonic vibrations, which is produced by a frequency compensation coupler or free mass, to produce the hammering action with relatively low axial-force required. The invention can also be fitted with irrigation and aspiration capabilities. The invention is furnished with a body sensor-feedback apparatus, which provide feedback to the operator as to the optimal frequency and power use of the generator. The assembly presented also has a coolant jacket to keep the drill or coring apparatus at optimum temperature prolonging the life of the instrument and the quality of the sample. The invention can be used in numerous applications one of such notable application is on the field of orthopedics.
