Abstract

Adapter assemblies are provided for selectively interconnecting a surgical end effector that is configured to perform at least a pair of functions and a surgical device that is configured to actuate the end effector, wherein the end effector includes a first axially translatable drive member and a second axially translatable drive member, and wherein the surgical device includes a first rotatable drive shaft and a second rotatable drive shaft.

Claims

1. An adapter assembly for selectively interconnecting a surgical end effector and a surgical device that is configured to actuate the end effector, the end effector including an axially translatable drive member, and the surgical device including a rotatable drive shaft, the adapter assembly comprising:

a housing configured to connect to the surgical device and to operatively couple to the rotatable drive shaft of the surgical device;

an inner housing tube supported by the housing and defining an internal cavity, the inner housing tube having an outer surface including a heat dissipation feature formed therein; and

a drive converter assembly at least partially disposed within the internal cavity of the inner housing tube, the drive converter assembly interconnecting the rotatable drive shaft of the surgical device and the axially translatable drive member of the end effector.

2. The adapter assembly according to claim 1, wherein the drive converter assembly further includes:

a first end configured to couple to the rotatable drive shaft of the surgical device; and

a second end configured to couple to the axially translatable drive member of the end effector, wherein the drive converter assembly converts and transmits a rotation of the rotatable drive shaft of the surgical device to an axial translation of the axially translatable drive member of the end effector.

3. The adapter assembly according to claim 1, wherein the heat dissipation feature includes at least one groove formed on the outer surface of the inner housing tube.

4. The adapter assembly according to claim 3, wherein the at least one groove includes a plurality of grooves defining a plurality of ridges on the outer surface of the inner housing tube.

5. The adapter assembly according to claim 4, wherein each of the plurality of grooves extends annularly about the outer surface of the inner housing tube.

6. The adapter assembly according to claim 4, wherein each of the plurality of grooves extends longitudinally along the outer surface of the inner housing tube.

7. The adapter assembly according to claim 1, wherein the inner housing tube includes at least one drainage opening formed therein.

8. The adapter assembly according to claim 7, wherein the at least one drainage opening includes a plurality of apertures disposed along one side of the inner housing tube.

9. The adapter assembly according to claim 8, wherein the plurality of apertures extend in a longitudinal direction.

10. A surgical system comprising:

a surgical end effector including an axially translatable drive member;

a surgical device configured to actuate the end effector and including a rotatable drive shaft; and

an adapter assembly including;

a housing configured to connect to the surgical device and to operatively couple to the rotatable drive shaft of the surgical device;

an inner housing tube supported by the housing and defining an internal cavity, the inner housing tube having an outer surface including a heat dissipation feature formed therein; and

a drive converter assembly at least partially disposed within the internal cavity of the inner housing tube, the drive converter assembly interconnecting the rotatable drive shaft of the surgical device and the axially translatable drive member of the end effector.

11. The surgical system according to claim 10, wherein the drive converter assembly further includes:

a first end configured to couple to the rotatable drive shaft of the surgical device; and

a second end configured to couple to the axially translatable drive member of the end effector, wherein the drive converter assembly converts and transmits a rotation of the rotatable drive shaft of the surgical device to an axial translation of the axially translatable drive member of the end effector.

12. The surgical system according to claim 10, wherein the heat dissipation feature includes at least one groove formed on the outer surface of the inner housing tube.

13. The surgical system according to claim 12, wherein the at least one groove includes a plurality of grooves defining a plurality of ridges on the outer surface of the inner housing tube.

14. The surgical system according to claim 13, wherein each of the plurality of grooves extends annularly about the outer surface of the inner housing tube.

15. The surgical system according to claim 13, wherein each of the plurality of grooves extends longitudinally along the outer surface of the inner housing tube.

16. The surgical system according to claim 10, wherein the inner housing tube includes at least one drainage opening formed therein.

17. The surgical system according to claim 16, wherein the at least one drainage opening includes a plurality of apertures disposed along one side of the inner housing tube.

18. The surgical system according to claim 17, wherein the plurality of apertures extend in a longitudinal direction.
