摘要:
An apparatus comprises a body, a shaft assembly, an end effector assembly, and a drive assembly. The body may include a handpiece with an integral motor. The shaft assembly may include two pairs of concentric shafts. The end effector assembly may include arms that selectively grasp and release a suturing needle. The drive assembly is operable to drive the end effector assembly via the shaft assembly. The drive assembly is operable to convert a single rotary input into at least two rotary outputs. In some versions, the drive assembly comprises a plurality of shaft assemblies that include an input shaft, a first output shaft, a second output shaft, and a third output shaft. The drive assembly is operable to selectively rotate and hold the shaft assemblies in accordance with a predetermined sequence, such as to perform tissue suturing through a trocar in a minimally invasive surgical procedure.
