1. An adapter assembly for selectively interconnecting a surgical end effector that is configured to perform a function and a surgical device that is configured to actuate the end effector, the end effector including at least one axially translatable drive member, and the surgical device including at least one rotatable drive shaft, the adapter assembly comprising:
a housing configured and adapted for selective connection with the surgical device and to be in operative communication with each of the at least one rotatable drive shaft of the surgical device; an outer tube having a proximal end supported by the housing and a distal end configured and adapted for selective connection with the end effector, wherein the distal end of the outer tube is in operative communication with each of the at least one axially translatable drive member of the end effector; at least one coupling sleeve rotatably supported in the housing, the at least one coupling sleeve being configured and adapted for selective connection to the at least one rotatable drive shaft of the surgical device; at least one drive converter assembly for selectively interconnecting a respective one of the at least one rotatable drive shaft of the surgical device and one of the at least one axially translatable drive member of the end effector, wherein the at least one drive converter assembly includes:
a first end that is releasably connectable to a first rotatable drive shaft of the surgical device and a second end that is releasably connectable to a first axially translatable drive member of the end effector;a hollow tube rotatably disposed within the housing and the outer tube, wherein a proximal end of the hollow tube is in operative communication with the coupling sleeve;a coupling nut connected to a distal end of the hollow tube; andan axially translatable drive shaft having a threaded proximal portion connected to the coupling nut and a distal portion configured and adapted for selective connection to the first axially translatable drive member of the end effector, wherein the at least one drive converter assembly converts and transmits, within the adapter assembly, a rotation of the first rotatable drive shaft of the surgical device to an axial translation of the first axially translatable drive member of the end effector, wherein rotation of the first rotatable drive shaft of the surgical device results in rotation of the at least one coupling sleeve, the hollow tube and the coupling nut, and wherein rotation of the coupling nut results in axial translation of the axially translatable drive shaft of the at least one drive converter assembly and of the first axially translatable drive member of the end effector. |
