Title
(EN) Bone positioning device and method
(ZH) 骨定位装置和方法
Abstract
(EN)
A device (400) for positioning a bone cutting guide (432) on a tibia may- include a tibial attachment member (402) including a varus/valgus adjustment member (406), an anterior/posterior adjustment member (408), and at least one aperture for coupling with a pin inserted into the tibia. The device may also include a stationary arm (410) fixedly attachable to the tibial attachment member (402) at one end and extending to a pivot joint (412) at an opposite end. Further, the device may include a pivoting arm (414) movably attached at one end to the stationary arm (410) at a pivot joint (412). The device may also include a light emitter (416) attachable to the pivoting arm (414). A depth selection member (424) movably coupled to the stationary arm (410) and configured to removably attach to the bone cutting guide (432) can also be included in the device. A stylus (426) removably attachable to the bone cutting guide (432) can also be part of the device.

(ZH)
用于在胫骨上定位骨切割引导件(432)的装置(400)可包括胫骨附接件(402),胫骨附接件包括内/外调节构件(406),前/后调节构件(408),和用于与插入胫骨内的销接合的至少一个孔隙。该装置可还包括固定臂(410),固定臂在一端能够固定地附接到胫骨附接件(402)并且在相反端延伸至枢转接头(412)。另外,该装置可包括枢转臂(414),枢转臂在一端在所述枢转接头(412)处被可动地附接到固定臂(410)。该装置可还包括可附接到枢转臂(414)的发光器(416)。可动地接合到固定臂(410)并且被配置用于可移除地附接到骨切割引导件(432)的深度选择件(424)也可以包括在本装置中。可移除地附接到骨切割引导件(432)的接触突部(426)也可以是本装置的一部分。
