Abstract: A suturing instrument includes a suturing head that is coupled to the shaft of an elongate body member of the instrument by a connector member which may be biased in either a linear orientation along the longitudinal axis of the shaft or any one of a variety of non-linear orientations with respect to the shaft's longitudinal axis. The connector member can comprise a resilient material such that an external force may be applied to the suturing head and move the suturing head from a biased orientation (e.g., linear) to an unbiased orientation (e.g., non-linear). Once the external force is removed, the resiliency of the connector member allows the suturing head to return from the unbiased orientation to the biased orientation. Therefore, a user may adjust the shape of the instrument by applying or removing an external force on the suturing head.

Abstract translation: 缝合器具包括缝合头，该缝合头通过连接器构件联接到器械的细长本体构件的轴上，该连接器构件可以沿着轴的纵向轴线的线性取向或各种非 - 相对于轴的纵向轴线的线性取向。 连接器构件可以包括弹性材料，使得外力可以施加到缝合头并且将缝合头从偏置的取向（例如线性）移动到无偏向的方向（例如，非线性）。 一旦去除了外力，连接器构件的弹性允许缝合头从无偏向的方向返回到偏置方向。 因此，用户可以通过施加或去除缝合头上的外力来调节器械的形状。

Abstract: A suturing instrument for placing multiple sutures include an elongate body engaged to a handle. A suturing head extends from a distal end of the elongate body, and the suturing head is articulable relative to the elongate body. Both a first needle carrier and a second needle carrier are movable into and out of the suturing head. A first actuator allows controlled movement of the first needle carrier, and this first actuator extends from a proximal end of the handle. A second actuator allows controlled movement of the second needle carrier, and this second actuator also extends from the proximal end of the handle. The suturing head can be articulated within a range of about 0 degrees to about 30 degrees, as measured from a longitudinal axis running along the length of the elongate body, and this variable articulation angle of the head allows deployment of the first needle carrier and the second needle carrier at various orientations with respect to the longitudinal axis.
