Hand held surgical handle assembly, surgical adapters for use between surgical handle assembly and surgical end effectors, and methods of use
First Claim
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 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 inner housing tube having a proximal end supported by the housing, the inner housing tube defining an internal cavity and at least one aperture opening into the cavity;
a distal coupling assembly disposed at a distal end of the inner housing tube, wherein the distal coupling assembly is configured to selectively connect with the end effector;
at least one drive converter assembly for 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 is at least partially disposed within the cavity of the inner housing tube, the at least one drive converter assembly including;
a first end that is connectable to a first rotatable drive shaft of the surgical device; and
a second end that is connectable to a first axially translatable drive member of the end effector, wherein the at least one drive converter assembly converts and transmits 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; and
a plurality of seals disposed between the inner housing tube and the at least one drive converter assembly so as to prevent ingress of fluid into the cavity of the inner housing tube, wherein the plurality of seals includes a first seal interposed between the distal coupling assembly and a drive tube of the at least one drive converter assembly, the first seal being an X-ring gasket.
