A percutaneous surgical instrument for de-bulking calculi or drilling bone includes an actuator for generating vibrations at ultrasonic frequencies and a horn coupled to said actuator for amplifying the actuator vibration. A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and under said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

Dual probe with floating inner probe

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

A percutaneous surgical instrument for de-bulking calculi or drilling bone includes an actuator for generating vibrations at ultrasonic frequencies and a horn coupled to said actuator for amplifying the actuator vibration. A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and over said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

Dual probe

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.

Acute care method and apparatus for treating a patient experiencing thrombotic vascular occlusion includes introducing a selected dose of an active agent proximate a vascular occlusion in the patient in order to lyse the vascular occlusion and radiating the vascular occlusion and active agent.

Apparatus for emergency treatment of patients experiencing a thrombotic vascular occlusion

An ultrasonic resonator comprising a wire member with an elongated shaft having a proximal end and a distal end, the proximal end further including a filler material disposed within the proximal end; a crimp screw with an annular end and a threaded end, the annular end adapted to receive and fixedly secure the proximal end of the wire member, the annular end being crimped after the proximal end of the wire member is inserted within the annular end of the crimp screw; an ultrasonic transducer adapted to receive the threaded end of the crimp screw; and the ultrasonic transducer operatively connected to an ultrasonic generator.

An arm assembly for supporting a surgical lighthead of a surgical light apparatus. The arm assembly includes a first arm and a second arm pivotally coupled to the first arm about a main pivot axis. A rod extends within an interior region of the second arm. A link is coupled to the rod to the first arm for pivoting movement about a link pivot axis that is spaced apart from the main pivot axis. A spring extends within the interior region of the second arm. The spring exerts a force on the rod and the link to counterbalance the surgical lighthead. A space filler includes an outer cover coupled to the first arm and formed to include a first slot and an inner cover nested within the outer cover and formed to include a second slot.

Support arm for surgical light apparatus

Apparatus and method is provided for enhancing the action of anti-cancer agents, which includes the introduction of anti-cancer agent into or proximate a tumor within a body and thereafter introducing ultrasonic energy at the solid tumor with the introduced anti-cancer agent. The ultrasonic energy is sufficient to increase the anti-cancer activity on the solid tumor without significant heating of the solid tumor or surrounding tissue.

Ultrasound enhanced chemotherapy

A surgical lighthead is provided with an outer cover, an inner reflective component, and handles disposed in recesses in the outer cover. The handles do not extend substantially beyond the outer surface of the outer cover. The recesses in the outer cover are spaced apart from the inner component. The handles and recesses are formed by multi-component handle assemblies shrink fit to eliminate gaps in the seams between the components.

Handle for surgical light apparatus

A multiple transducer assembly and method for coupling ultrasonic energy to a body for thrombolysis of vascular thrombi is provided. The assembly includes a catalytic transducer apparatus including a plurality of transducers for transmitting ultrasound into a medical target transcutaneously. Each transducer includes a front mass having structure which optimizes the transmission of ultrasound into the body. The transducers may share a common front mass. A reservoir for containing a cooling conductive medium between the front mass and the body surface is provided, and is contained within the housing. In addition, the catalytic transducer includes an irrigation manifold, disposed through a center of the front mass, for directing the medium into the reservoir generally along a perimeter thereof. The front mass includes an apex for accumulating expelled gasses. A sloped surface of the front mass functions to direct expelled gasses toward the apex and through an outlet provided by the irrigation manifold. The medium may be circulated from a degassing tank as well as a heat exchange unit in order to maintain a desired reservoir temperature at the body surface. In the multiple transducer arrangement, the transducers may share a common cooling reservoir. A flexible blanket may be provided for collectively housing a desired number and arrangement of transducers.

An arm assembly for supporting a surgical lighthead of a surgical light apparatus includes a first arm and a first clevis appended to the first arm and having a first stop surface and a second stop surface. The arm assembly also includes a second arm formed to include an interior region and a second clevis appended to the second arm and having a third stop surface and a fourth stop surface. The surigcal lighthead is supported by the second arm. The second arm and second clevis are pivotable about a main pivot axis relative to the first arm and first clevis between a first position in which the third stop surface engages the first stop surface to limit pivoting movement of the second clevis and second arm in a first direction and a second position in which the fourth stop surface engages the second stop surface to limit pivoting movement of the second clevis and second arm in a second direction
