    • Devices and methods are provided for performing microfracture surgery on an articular surface in a joint space. A surgical tool comprising an elongated body and a distal probe is provided. The probe is coupled to the elongated body and is adapted to be inserted in the joint space. The probe is positioned over the articular surface. A first and second channel through the subchondral bone into the marrow cavity are created with perforating elements, fluid jets, laser beams, or other channeling methods. The second channel is discrete from the first channel and is separated therefrom by a predetermined distance. The first channel and the second channel may be simultaneously created. In this way, a microfracture procedure is performed faster and with greater precision than existing techniques and with less risk of thermal damage and other complications.
    • 提供了用于在关节空间中的关节表面上进行微创骨折手术的装置和方法。 提供了包括细长主体和远端探针的手术工具。 探针耦合到细长主体并且适于插入关节空间中。 探针位于关节面上方。 通过软骨下骨进入骨髓腔的第一和第二通道用穿孔元件,流体射流,激光束或其它引导方法产生。 第二通道与第一通道离散并且与之隔开预定距离。 可以同时创建第一通道和第二通道。 以这种方式,微裂缝程序比现有技术更快,更精确地执行,并且具有较少的热损伤和其他并发症的风险。
