Alternatively, the shield can include an integral attachment portion configured to engage the bone fixation assembly directly. | 2020-12-24 |
20200397485 | MEDICAL INSERTING APPARATUS - A medical inserting apparatus includes a screw nail which is inserted into a human body, a driver which inserts the screw nail into the human body, a current generator disposed in the driver to generate a predetermined current, a current meter disposed in the driver to measure the current, and a conductor element disposed in the screw nail and the driver along a lengthwise direction including an exposed portion to outside, wherein the conductor element includes a forward conductor element connected to the current generator to allow the current generated by the current generator to flow into the human body, and a reverse conductor element having one end electrically connected to the forward conductor element and the other end connected to the current generator, and including a variable resistor and the current meter installed to allow the current generated by the current generator to flow to the current meter by current division with resistance of the human body. | 2020-12-24 |
20200397486 | Rod Reducer - A rod reducer including a housing defining an opening, a body member defining an opening and a slot, a shaft disposed through the opening of the housing and coupled to the opening of the body member, an anvil including a linkage extending therefrom, the linkage coupled to the body member and the anvil, a plurality of arm members, and a biasing element disposed between the body member and the anvil. A pin of the linkage is slidably disposed within the slot, and the biasing element is configured to bias the anvil distally with respect to the body member. Rotation of the shaft translates into linear movement, relative to the housing, of the shaft, the body member, and the anvil. The arm members are coupled to the housing and movable towards a parallel configuration as the anvil is advanced away from the housing to engage a bone screw. | 2020-12-24 |
