摘要： A battery and control module to which a powered surgical tool is releasably attached. Internal to the module there is: a cell for energizing the tool; a sensor for monitoring an operational state of the tool; a sensor for monitoring a trigger external to the module; and a control circuit. Based on the signals output by the sensors, the control circuit selectively applies energization signals from the cell to the power generating unit internal to the surgical tool. In some versions of the invention, the trigger is attached to the module.

摘要： A knee arthroplasty system may have a femoral joint prosthesis with a femoral bone engagement surface with an anterior portion, a posterior portion, and a distal portion that connects the anterior portion to the posterior portion. A first femoral anchoring member may protrude from the distal portion, and may be connected to the anterior portion with a primary femoral web. A tibial resection guide may have a base member and a guide member with a slot that guides a cutting blade to resect the tibial plateau. The guide member may slide along an arcuate path relative to the base member.

摘要： Ultrasonic surgical device is provided. The device includes a shell which holds an energy converter and an amplitude-change pole. The energy converter may include piezoceramic stack that converts electrical signals into mechanical ultrasonic movement in the longitudinal direction of the device. The amplitude-change pole is a mechanical amplifier that uses mass differentials to amplify the ultrasonic motion. A cutting instrument interfaces with the amplitude-change pole. The system also includes a rotary drive device comprising a drive motor also axially arranged with the cutting instrument. The motor rotates the amplitude-change pole, energy converter, and ultimately the cutting instrument. In some embodiments the rate of rotation is at 40-1000 rpm, at 50-650 rpm and at 60-350 rpm depending on configuration. In some cases the user may be enabled to alter the rotational speed within these ranges

摘要： A method and instrumentation for performing a patellofemoral arthroplasty orthopedic procedure includes coupling an anterior cutting block to a femur of a patient such that the cutting block references local anatomy of the femur. The anterior cutting block is used to perform a number of bone cuts to establish a trochlear cavity in the femur. The trochlear cavity is formed such that a trochlear prosthesis may be inset into the cavity and substantially flush with the surrounding cartilage. A finishing burring guide and burr bit may be used to detail the shape and/or size of the trochlear cavity. Additionally, a trochlear drill guide may be used to facilitate establishing peg holes in the patient's femur to receive corresponding pegs of the trochlear prosthesis.

摘要： A surgical sagittal saw blade with a static blade bar, an oscillating blade head and at least one drive rod disposed in the blade bar that pivots the blade head. The blade bar is formed with an opening located proximal to the distal end of the blade. A finger connected to a distal end of the drive rod is located above the drive rod so as to be seated in the opening in the blade bar. The finger extends forward of the drive rod over a base section of the blade head. A pin that extends from the finger pivotally connects the blade head to the finger and, by extension, to the drive rod.

摘要： A number of improvements are provided relating to computer aided surgery utilizing an on tool tracking system. The various improvements relate generally to both the methods used during computer aided surgery and the devices used during such procedures. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled using the OTT device. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure including the rate of and type of data processed depending upon a CAS mode.

摘要： A measurement system and method for determining a depth of penetration of a working portion of a surgical instrument (e.g., a rotating drill bit in a bore). A first sensor outputs a first signal representative of a displacement of the leading edge of the drill bit in the bore. A second sensor outputs a second signal representative of a force applied to the leading edge of the drill bit. A processor outputs a third signal representative of the depth of penetration of the leading edge of the drill bit when the leading edge of the drill bit passes from a first medium having a first density to a second medium having a second density. The third signal is based on the first and second signals.

摘要： A surgical system for cutting tissue of a patient includes an outer housing and a reciprocating assembly structurally configured to carry a cutting tool in a reciprocating motion. An actuator knob is manually accessible to the user and may be fixed axially to the outer housing. The reciprocating assembly may reciprocate relative to the actuator knob. The actuator knob may be configured for rotational movement between a lock position and an unlock position. The system may also include a locking mechanism configured to retain a cutting tool within the reciprocating assembly. The locking mechanism may be responsive to movement of the actuator knob to maintain the tool within the output shaft when the actuator knob is in the lock position and permit removal of the tool when the actuator knob is in the unlock position. Surgical cutting tools, such as blades include thickness enhancing features.
