摘要： Methods and devices are provided for retracting tissue. In one exemplary embodiment, a retractor is provided that includes a base, a plurality of blades extending from the base, and an actuator coupled to the base and operatively connected to the blades. The actuator can be configured to be actuated to move the blades relative to the base, thereby allowing the blades to retract tissue. The actuator can be self-locking so as to allow the blades to be freely movable within their entire range of motion relative to the base through actuation of the actuator without using another mechanism to lock the blades in a fixed position and to unlock the blades from the fixed position. The retractor can be formed from one or more radiolucent materials.

摘要： Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.

摘要翻译： 本文公开了骨锚和外科器械（例如，骨挖掘器，驱动器等），其包括集成引导尖端。 使用这些锚固器或仪器可以消除常规骨锚安装程序中的一个或多个步骤，从而提高手术效率和安全性。 例如，外科器械可以包括引导突起，其被配置为当外科器械联接到骨锚时插入穿过骨锚固件中的插管。 手术器械还可以包括用于调节引导突起相对于骨锚的位置的各种机构。 引导突起可以代替在典型插入过程中使用的针，探针和导丝。 骨锚还可以包括集成的敲击特征，以消除对单独的骨头敲击器械的需要。 因此，在一些实施例中，可以在单个步骤中执行靶向，攻丝和驱动骨锚。
