摘要： An occipitocervical fixation system includes a plate for securing to the occiput and at least one pre-bent rod. The plate includes holes for receiving bone fasteners, and at least one clamping assembly for retaining a portion of a rod. The clamping assembly is selectively pivotable and lockable in place to fix the position of the rod.

摘要： A retractor with multiple blades for use in surgery. The retractor may comprise first and second elongated portions which are pivotally connected to each other. A first blade may be connected to the first elongated portion and a second blade may be connected to the second elongated portion. The retractor may also comprise a sliding bar having a third blade. The sliding bar may be associated with the first and second elongated portions such that movement of the elongated portions relative to each other may result in movement of the sliding bar and, consequently, movement of the third blade relative to the first and second blades. In one embodiment, the retractor may comprise a tension limiting device so that the third blade may remain relatively stationary as the first and second blades are moved. The retractor may also comprise a fourth blade operatively connected to the first and second elongated portions. The fourth blade may be moved independently of the other blades or may move with the other blades. Also disclosed is a method of retracting tissue.

摘要翻译： 具有多个刀片的牵开器用于手术。 牵开器可以包括彼此枢转地连接的第一和第二细长部分。 第一叶片可以连接到第一细长部分，并且第二叶片可以连接到第二细长部分。 牵开器还可以包括具有第三叶片的滑动杆。 滑动杆可以与第一和第二细长部分相关联，使得细长部分相对于彼此的移动可导致滑动杆的移动，并且因此导致第三叶片相对于第一和第二叶片的运动。 在一个实施例中，牵开器可以包括张力限制装置，使得当第一和第二叶片移动时，第三叶片可保持相对静止。 牵开器还可以包括可操作地连接到第一和第二细长部分的第四叶片。 第四刀片可以独立于其他刀片移动，或者可以与其他刀片一起移动。 还公开了一种缩回组织的方法。
