    • An instrument (2) for use in manipulating an implant component, which has a face with two spaced apart edges, comprises a housing (4) and first and second arms (72,74) each having a finger (76,78) which can engage the implant component at respective edges of the face, the arms being mounted for sliding movement relative to the housing in which the fingers on the arms move along a common axis. A gear mechanism (70,124), by which the first and second arms are linked to one another, ensures that sliding movement of the first arm in a first direction relative to the housing is accompanied by equal sliding movement of the second arm in a second direction which is opposite to the first direction. A shaft (122) is mounted in the housing so that it can slide along a shaft axis which is perpendicular to the axis along which the fingers slide, the shaft has a bed (46) at its end for engaging the face of the implant component. The instrument includes a ramp surface (32,34,36,38) and a follower (125) which can move along the ramp surface with one of the ramp surface and the follower being fixed relative to the shaft so that the sliding position of the shaft relative to the housing along the shaft axis is determined by the position of the follower on the ramp surface. The position of the follower on the ramp surface varies according to the positions of the first and second arms relative to the housing.

    • An auto-extensible device, which can be incorporated in a tissue distractor (1), has an electrorestrictive device (50) which has a proximal end (51) mounted in a first body member (2) and which is located within an elongate tubular member (4) that is externally screw threaded and carries a first gear ring (40) and a second gear ring (41) threaded thereon. Upon applying a voltage to the electrorestrictive device (50) a linear bearing guide (21) together with a second body member (3) is caused to move distally with respect to the first body member (2) and hence, by interference with the second gear ring (41), to carry with it the elongate tubular member (4). This movement produces a first gap (A) between the second body member (3) and the first body member (2) as well as a second gap (B) between a distal end surface of the first body member (2) and the first gear ring (41). A first motor (42) then drives a first spur gear (45) engaged with the first gear ring (40) so as to cause it to move proximally along the elongate tubular member (4) until it abuts the first body member (2) and thereby closes the second gap (B). Next the voltage is allowed to drop to zero causing the electrorestrictive device (50) to contract again, thereby causing the first gap (A) to close and a third gap (C) to open up between a second gear ring (41) screw threadedly engaged with the external screw thread (ET) on the tubular member (4) and a distal surface of the second body member (3). A second motor (46) then drives a second spur gear (49) engaged with the second gear ring (41) so as to move the second gear ring (41) proximally of the elongate tubular member (4) and to cause it to close the third gap (C).
    • 可以包括在组织牵引器(1)中的自动延伸装置具有电绝缘装置(50),其具有安装在第一本体构件(2)中的近端(51),并且位于细长管状 构件(4),其外螺纹并带有螺纹连接在其上的第一齿圈(40)和第二齿圈(41)。 当向电气限制装置(50)施加电压时,使线性轴承导向件(21)与第二主体构件(3)一起相对于第一主体构件(2)向远侧运动,因此通过与第二主体构件 齿圈(41),以便承载细长管状构件(4)。 该移动在第二主体构件(3)与第一主体构件(2)之间产生第一间隙(A)以及在第一主体构件(2)的远端表面与第一主体构件 齿圈(41)。 然后,第一马达(42)驱动与第一齿圈(40)接合的第一正齿轮(45),以使其沿着细长管状构件(4)向近侧移动,直到其抵靠第一主体构件(2) 从而封闭第二间隙(B)。 接下来,允许电压下降至零,使得电气限制装置(50)再次收缩,从而导致第一间隙(A)闭合,并且第三间隙(C)在螺纹的第二齿圈(41)螺钉 与管状构件(4)上的外螺纹(ET)和第二主体构件(3)的远侧表面接合。 然后,第二马达(46)驱动与第二齿圈(41)接合的第二正齿轮(49),以使第二齿圈(41)在细长管状部件(4)的近侧移动并使其闭合 第三个差距(C)。
