  • Ergonomic handpiece for laparoscopic and open surgery
    Patent number: 9655601
    Abstract: A surgical tool having an elongate shaft, with a directional operative element at its distal end, is provided with a mechanism to rotate the shaft and the operative element about a longitudinal axis shaft. This allows the operative element to be aligned with an element of tissue without excessive hand movement by the user. In a preferred version, the mechanism is electrically powered and is regulated to produce smooth, controlled, accurate motion between selected rotational positions. The mechanism may include a linear magnetic motor drive to move a drive element longitudinally along the tool. This drive element is engaged with a helical formation on a drive shaft, such that longitudinal motion of the drive element is converted to rotational motion of the drive shaft, and of the shaft and operative element, to which the shaft is mounted.
