    • Instruments and a method for minimally invasive surgery are disclosed. An implant manipulation instrument (20) comprises a driver (23) for locking a locking cap (19) against a spinal fixation rod (12) in a first spinal fixation device (11), and an actuator (22). The driver extends through the actuator and is rotatable with respect to it. An end (30) of the actuator is configured to fit over the rod, on which a second spinal fixation device (ll1) may be mounted. Pivoting (F) of the actuator with respect to the driver moves the second spinal fixation device closer to the first. An anchor delivery instrument (300) comprises a guide (302) including a cannulated body (303) to guide a surgical component (7), at least a first radio-opaque marker (313), and at least a second radio-opaque marker (330) distal to the first. A position of the first marker relative to the second on a radio image indicates whether the orientation of the guide is as desired.
    • 公开了用于微创手术的仪器和方法。 植入物操纵仪器(20)包括用于在第一脊柱固定装置(11)中将锁定帽(19)锁定在脊柱固定杆(12)上的驱动器(23)和致动器(22)。 驱动器延伸穿过致动器并且可相对于其旋转。 致动器的端部(30)构造成配合在杆上,第二脊柱固定装置(111)可以安装在杆上。 致动器相对于驾驶员的枢转(F)使第二脊柱固定装置更靠近第一脊柱固定装置。 锚固器输送器具(300)包括导向器(302),该导向器(302)包括用于引导手术部件(7)的插管体(303),至少第一不透射线标记(313)和至少第二不透射线标记 (330)远离第一个。 在无线电图像上的第一标记相对于第二标记的位置指示引导件的取向是否如所期望的那样。
