Abstract: A surgical instrument includes an elongated shaft, with components arranged in the shaft. The elongated shaft is slightly curved. Arranged on a proximal end of the surgical instrument is an actuation device in the form of a lever mechanism and rotary knob. A force transmission element in the form of a plastic hollow section is arranged in the shaft. The force transmission element is a plastic section designed for transmitting compressive and tensile forces. The plastic section is provided with a plurality of longitudinally extending channels. Therefore, the plastic section does not only serve as a force transmission element, but electric lines and a pull-push shaft may additionally extend in the channels. The longitudinal channels may be used for supplying cooling media for the electrodes or the thermo-fusion device or for feeding agents promoting wound repair. The plastic section is electrically insulating, so that the risk of short-circuits is reduced.

In order to use the drive control device for the most varied application cases, a parameter specification device is provided upstream of the motor control unit. The parameter specification device determines the current medical application on the basis of a detected state or state history of the surgical motor system, in particular of the electric motor, selects a control mode which is suitable for the medical application, and gives the motor control unit the open or closed loop parameters that the open or closed loop control profile of the electric motor corresponds to the selected control mode.

Abstract: A surgical clip is provided having two clip arms and a resiliently flexible element via which the two clip arms are connected to each other. The two clip arms each have a first free end, these first free ends being held parallel to and in contact with each other with a predetermined closing force by the resiliently flexible element when the clip is in a rest position. The clip arms are held at a second end opposite the free end on the resiliently flexible element. The clip arms have between their first and second ends sections configured to cross each other. The clip arms further have stop elements configured to complement each other. The stop elements are adapted to be brought in mutual contact when the clip is transferred from the rest position to an application position in which the free ends are spaced apart from each other.

Abstract: A method of controlling electrosurgical power delivery is based on a comparison of sensed tissue impedance to various impedance threshold values. Energy is delivered to tissue in a sealing cycle as a series of pulses. A pulse has a profile with a preset energy starting value that increases at a ramping rate to a preset end value. Sensed impedance data are monitored throughout each pulse and compared to each of an impedance threshold value for RF setpoint, an impedance threshold value for cumulative time, and an impedance threshold value for energy cutback. Based on sensed impedance during a pulse, the profile of a subsequent pulse can be modified. In the event of a high impedance event that reflects low tissue presence, energy may be cutback. A sealing cycle is stopped when a cumulative amount of time with an impedance value over the impedance cumulative time threshold value reaches a limit.

Abstract: A spinal rod persuader, system and method can include an outer tube, an inner tube, and a locking element. A first actuation mechanism can be movable in a linear fashion along a longitudinal axis direction to cause the locking element to move in a linear fashion over the inner tube and to lock the inner tube onto a pedicle screw. A second actuation mechanism can be rotated to cause the outer tube to move in a longitudinal axis direction with respect to the inner tube to push the spinal rod into a final position with respect to the pedicle screw while the pedicle screw is locked to the inner tube. A slot and/or tab structure can be provided in the outer tube such that actuation of the slot/tab will allow disassembly of the inner tube, outer tube and locking element with respect to each other.

Abstract: A knee prosthesis having a femoral component with two condyles, an opening disposed between the two condyles, and a tibial component having bearing surfaces to engage and support each of the femoral component condyles. Moving the femoral and tibial components in flexion from about 0° to about 165° causes medial pivot rotation of the femoral component upon the tibial component. Rotation may be caused by interaction between an asymmetrical cam extending between the femoral condyles and a post disposed between the bearing surfaces and extending superior from the tibial component. Rotation may alternatively be caused by asymmetrical medial and lateral condyles which translate posteriorly upon respective medial and lateral bearing surfaces at disparate rates, without a femoral cam, a tibial post, or a post/cam contact surface. Embodiments of the knee prosthesis may be used in cruciate-substituting or cruciate-retaining procedures. Embodiments of the knee prosthesis may also prevent roll forward.
