The present invention discloses a ball probe ultrasonic bone removal device that is designed to assist surgeons with foraminotomy procedures. The device comprises a shaft at a first end of the device and a spherical ball tip at a second end of the device. In between the shaft and the ball tip is a foot piece that connects to the shaft through an angle. On the foot piece, serrations or a course surface cover a portion of the circumference of the foot piece. In some embodiments, serrations or a course surface may also cover a portion of the circumference of the shaft. The spherical ball tip is smooth and designed to cause no damage to the sensitive nerves and tissue in the intervertebral foramina, but the surface with the serrations or the course protrusions are designed to remove bone and tissue under ultrasonic movement (e.g., vertical vibration, rotational oscillation).

An ultrasonic surgical system includes an ultrasonic generator configured to provide an ultrasonic drive signal, and an ultrasonic transducer electrically coupled to the ultrasonic generator to receive the ultrasonic drive signal therefrom and configured, in response to the received ultrasonic drive signal, to produce a mechanical motion. The ultrasonic surgical system further includes a sensor configured to sense a frequency and a magnitude of the mechanical motion, and a controller configured to receive a target mechanical motion to be produced by the ultrasonic transducer and control the ultrasonic drive signal so that a frequency of the ultrasonic drive signal falls within a frequency range around a resonant frequency of the ultrasonic transducer, the frequency range corresponding to the target mechanical motion produced by the ultrasonic transducer.

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

A surgical tool may move a saw blade in a sagittal plane. The saw blade has a distal blade end with teeth. The surgical tool comprises a handpiece body and a carrier operatively attached to the handpiece body. The carrier is configured for oscillating movement about a pivot axis. A retainer is operatively attached to the carrier for concurrent movement and releasably secures the saw blade in the sagittal plane relative to the handpiece body. An actuator is coupled to the handpiece body to selectively oscillate the carrier relative to the handpiece body such that the retainer and the saw blade pivot back and forth about the pivot axis within the sagittal plane. An ultrasonic transducer is operatively attached to the handpiece body to selectively generate ultrasonic energy to resonate the saw blade such that the teeth at the distal blade end reciprocate proximally and distally within the sagittal plane.

A method for producing a surgical instrument is disclosed. The method comprises obtaining a handle, wherein the handle comprises a distal end comprising a shaft interface surface and a first set of magnetic elements. The method further comprises obtaining a shaft, wherein the shaft comprises a proximal end comprising a handle interface surface, a second set of magnetic elements, and a third set of magnetic elements. The method further comprises attaching the shaft to the handle, wherein the shaft interface surface is configured to engage the shaft at the handle interface surface, wherein an attractive magnetic force is configured to pull the handle towards the shaft when the first set of magnetic elements interact with the second magnetic elements, and wherein a repulsive magnetic force is configured to repel the handle from the shaft when the first set of magnetic elements interacts with the third set of magnetic elements.

A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the insulative surface. A second jaw member of the end effector assembly includes an ultrasonic blade body positioned to oppose the insulative surface of the first jaw member, and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the ultrasonic blade body and positioned to oppose the first and second electrically-conductive surfaces, respectively, of the first jaw member. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The first and second electrically-conductive surfaces of the second jaw member are movable, independent of the first jaw member, relative to the first jaw member and the ultrasonic blade body between a retracted position and an extended position.

Surgical devices and systems having rotating end effector assemblies for treating tissue are provided. Methods for using the same are also provided.

A method for controlling an operation of an ultrasonic blade of an ultrasonic electromechanical system is disclosed. The method includes providing an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade via an ultrasonic waveguide; applying, by an energy source, a power level to the ultrasonic transducer; determining, by a control circuit coupled to a memory, a mechanical property of the ultrasonic electromechanical system; comparing, by the control circuit, the mechanical property with a reference mechanical property stored in the memory; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the comparison of the mechanical property with the reference mechanical property.

A work tip for an ultrasonic surgical hand piece has a solid knife with a sharp distal edge. A first fluid tube located on one side of the knife and has open ends to receive or discharge fluid. A second fluid tube is located on the other side of the knife and is slidably connected with the knife. The second fluid tube has an opening at a distal end and a smaller side hole. During phacoemulsification the knife is vibrated independent of the fluid tubes. The second fluid tube has irrigation fluid passing from the opening and side hole, and the first fluid tube is positioned so as to receive fluid from the second tube. During I/A cleanup the second fluid tube receives aspiration fluid only through the side hole because the knife is positioned to block the aspiration fluid from entering through the opening.

A skin treatment apparatus, such as a microdermabrasion or dermaplaning apparatus, includes a housing having a top end and a bottom end, a treatment head attached to the top end of the housing and arranged to exfoliate skin within a treatment area, and a cooling member provided on the bottom end of the housing arranged to cool skin within the treatment area.
