Claims14
A force/rotation transmitting/converting assembly for interconnecting a drive shaft of a surgical device and an axially translatable drive member of a loading unit, wherein the force/rotation transmitting/converting assembly includes:
- a bearing assembly having a first through hole and a second through hole, the first through hole and the second through hole intersecting to define a cavity configured for housing a ball having a threaded bore formed therein, the threaded bore configured for threadably connecting to a threaded portion of the drive shaft of the surgical device.
A force/rotation transmitting/converting assembly for interconnecting a drive shaft of a surgical device and an axially translatable drive member of a loading unit, wherein the force/rotation transmitting/converting assembly includes:
- a receiving member that is connectable to a drive shaft of the surgical device, the receiving member including at least one spur gear;
- a driver including at least one spur gear configured for mating with the at least one spur gear of the receiving member, the driver defining a bore therethrough;
- and
- a force transmitting member that is connectable to a portion of the axially translatable drive member of the loading unit, the force transmitting member including:
- a sleeve configured to mate with the driver;
- an articulation bar configured to selectively engage the axially translatable drive member of the loading unit;
- and
- a bearing assembly defining a cavity configured for housing a ball having a threaded bore formed therein, the threaded bore configured for threadably connecting to a threaded portion of the drive shaft of the surgical device.
