Adapter assembly for interconnecting electromechanical surgical devices and surgical loading units, and surgical systems thereof
First Claim
1. An adapter assembly for selectively interconnecting a surgical loading unit that is configured to perform a function and a surgical device that is configured to actuate the loading unit, the loading unit 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 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 connection with the loading unit, 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 loading unit; and
a plurality of force/rotationtransmitting/converting assemblies, each of the plurality of force/rotationtransmitting/converting assemblies configured for interconnecting a respective one of the at least one rotatable drive shaft of the surgical device and a respective one of the at least one axially translatable drive member of the loading unit, wherein each of the plurality of force/rotation transmitting/converting assemblies includes;
a proximal rotation receiving member that is connectable to the respective one of the at least one rotatable drive shaft of the surgical device, each of the proximal rotation receiving members being arranged in a longitudinally extending common plane with one another; and
a distal force transmitting member that is connectable to the respective one of the at least one axially translatable drive member of the loading unit, each of the distal force transmitting members being connected to each of the proximal rotation receiving members, respectively, in such a manner whereby rotation of the proximal rotation receiving member is converted to axial translation of the distal force transmitting member;
wherein the plurality of force/rotation transmitting/converting assemblies converts and transmits a rotation of the respective one of the at least one rotatable drive shaft of the surgical device to an axial translation of the respective one of the at least one axially translatable drive member of the loading unit;
wherein the plurality of force/rotationtransmitting/converting assemblies includes a first force/rotation transmitting/converting assembly;
wherein the proximal rotation receiving member of the first force/rotation transmitting/converting assembly includes a first proximal drive shaft defining a threaded distal end; and
wherein the distal force transmitting member of the first force/rotation transmitting/converting assembly includes a distal drive member threadably connected to the threaded distal end of the first proximal drive shaft, wherein the first proximal drive shaft and the distal drive member are axially aligned with one another and with a rotational axis of the respective rotatable drive shaft of the surgical device.
