An insert for use with a vibrating surgical tool has a proximal end for mounting to the vibrating surgical tool and a shaft extending from the proximal end. A head is mounted to the shaft, is curved along the longitudinal axis, and the terminal end thereof defines an edge for disposing against an incision between bone and periosteum. A passage is formed through the shaft for water to be forced through the passage and out of apertures formed on opposite sides of the insert. The edge is formed on the terminal end of the head, which is formed on a curve from one lateral side to an opposite lateral side. The edge extends from a front face to a tapered rear surface. A front face of the head forms an angle with a longitudinal axis of the shaft.

An end effector of an instrument is positioned in a patient. An ultrasonic blade of the end effector is positioned against tissue in the patient. The ultrasonic blade is activated to vibrate ultrasonically while the ultrasonic blade is positioned against tissue. At least one electrode of the end effector is positioned against tissue in the patient. The at least one electrode is activated to apply RF electrosurgical energy to tissue against which the at least one electrode is positioned against tissue.

Provided is a system and medical device that includes self diagnosing control switches. The control switch may be slidable within a slot in order to control activation of some function of the medical device. Due to natural wear and tear of movement of a control switch, the distances along the sliding slot that correspond to how much energy is used for the function may need to be adjusted over time in order to reflect the changing physical attributes of the actuator mechanism. The self diagnosing control switches of the present disclosures may be configured to automatically adjust for these thresholds using, for example, Hall effect sensors and magnets. In addition, in some cases, the self diagnosing control switches may be capable of indicating external influences on the controls, as well as predict a time until replacement is needed.

A method of marking a tumor includes positioning a surgical instrument adjacent breast tissue, generating an image of a tumor in the breast tissue on a display using an ultrasonic probe of the surgical instrument, aligning a needle of the surgical instrument with the tumor using the image of the tumor generated on the display, deploying the needle from the ultrasound probe into the breast tissue, and deploying an elongated tissue marker from the needle into the tumor, thereby fixing a distal portion of the tissue marker in the tumor.

A surgical instrument includes a handle assembly; a shaft assembly and an end effector. The shaft assembly includes an exterior shaft, a first clutch positioned within the exterior shaft to drive a first function of the surgical instrument when engaged. A second clutch within the exterior shaft to drive a second function when engaged. A rotary driver is positioned within the exterior shaft and configured to rotate within the exterior shaft. The rotary driver includes a first clutch engagement mechanism to engage the first clutch and a second clutch engagement mechanism configured to engage the second clutch independent of the first clutch engagement mechanism engaging the first clutch, such that, at different times both the first clutch and the second clutch are engaged simultaneously only the first clutch is engaged only the second clutch is engaged and neither the first clutch nor the second clutch is engaged simultaneously.

A system comprising a surgical instrument is disclosed. The surgical instrument includes a handle, a shaft, a plurality of magnets, a plurality of sensors configured to determine a distance away from one or more of the plurality of magnets, and a processor communicatively coupled to the plurality of sensors. The processor is configured to determine a three dimensional change in position of the shaft by computing a three dimensional change in position of the one or more magnets, using the change in the distances determined by the one or more plurality of sensors.

A device for cutting bone tissue and, more particularly, a sonotrode suitable for use with an ultrasonic surgical instrument. The sonotrode has a head and a distal end piece, the distal end piece being equipped as a rectangular blade for cutting bones using mechanical vibration. The sonotrode has at least one structural element and the structural element is selected from the group including: a support structure, a lateral depression on each side, an increased width of the blade together with a slit at the distal end of the blade, or at least one lateral rib.

An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.

An ultrasonic cutting tip has a hollow shaft with a proximal and distal end. The proximal end is configured to be attached to an ultrasonic hand piece, and the distal end has a smooth continuous surface. An opening is located near the distal end of the hollow shaft. The opening is configured to cut vitreous when the cutting tip is vibrated ultrasonically in a torsional manner.

A surgical instrument includes: a handpiece; a movable member configured to transmit a driving force to a treating member to treat a subject by moving relatively to the handpiece; and a connector arranged inside the handpiece, and including a strip to apply a pressing force to the movable member. The movable member includes a first conductive portion formed therein. The connector includes a second conductive portion formed on the strip. The second conductive portion abutting against the first conductive portion to connect the movable member and the handpiece electrically. The second conductive portion of the connector is a molded interconnect device constituting a three-dimensional circuit.
