摘要： An instrument may be used to move a rod attached to vertebrae to an opening of a fixation device. Positioning the rod in the opening may properly align the vertebrae with respect to the vertebra attached to the fixation element. A fixation holder may be coupled to the fixation element. The holder may include a protrusion. The protrusion may engage a guide of the instrument during use. The protrusion and the guide may ensure that the rod is properly positioned within the opening in the connector. The instrument and holder may automatically align the rod to the opening without requiring manual manipulation of the rod or the fixation element. The fixation element may include a connector. The connector may be positioned within the fixation element so that removal of the connector from the fixation element is inhibited.
摘要翻译：可以使用仪器将连接到椎骨的杆移动到固定装置的开口。将杆定位在开口中可以使椎骨相对于附接到固定元件的椎骨适当地对准椎骨。固定架可以联接到固定元件。保持器可以包括突起。在使用期间，突起可以接合仪器的引导件。突起和引导件可以确保杆被适当地定位在连接器的开口内。仪器和支架可以自动将杆对准开口，而不需要手动操纵杆或固定元件。固定元件可以包括连接器。连接器可以定位在固定元件内，使得连接器从固定元件的移除被禁止。

摘要： A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. The distractor includes blades that are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. The jaws include a mating fixture and the blades include a mating portion for removable association with the mating fixture.
摘要翻译：用于分离相邻元件（如椎骨）的牵引器。牵引器优选地具有剪刀式分心机构，无论是在简单的剪刀或双作用剪刀配置中。牵引器包括可从牵引器的钳口移除的刀片，使得根据患者和使用牵引器的情况可以使用不同的刀片。夹爪包括配合夹具，并且刀片包括用于与配合夹具可拆卸联接的配合部分。

摘要： A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. Additionally, one or more of the blades, distracting mechanism, and handles are offset with respect to the other to facilitate visualization and to increase the space available for an implant holder. The blades are configured to enhance versatility of the distractor. In a first embodiment, the blades are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. In a second embodiment, curved portions are provided between the blades and jaws such that the blades are offset from the jaws in a smooth transition which does not expose sharp edges to internal organs or vasculature of the patient. In a third embodiment, a pair of blades is provided on each jaw such that an implant may be inserted between the spaced apart blades without having a blade engage an external blade-receiving slot in the implant.
摘要翻译：用于分离相邻元件（如椎骨）的牵引器。牵引器优选地具有剪刀式分心机构，无论是在简单的剪刀或双作用剪刀配置中。此外，一个或多个刀片，牵引机构和手柄相对于另一个偏移，以便于可视化并增加可用于植入物保持器的空间。刀片被配置为增强牵引器的多功能性。在第一实施例中，叶片可以从牵引器的夹爪移除，使得根据患者和使用牵引器的情况可以使用不同的叶片。在第二实施例中，弯曲部分设置在叶片和夹爪之间，使得叶片以平滑的过渡方式从钳口偏移，其不会使锋利的边缘暴露于患者的内部器官或脉管系统。在第三实施例中，在每个钳口上设置一对刀片，使得植入物可以插入在间隔开的刀片之间，而不需要刀片与植入物中的外部刀片容纳槽接合。
