Abstract

A handheld electromechanical surgical device includes a non-sterile power-pack having a drive component(s) including a rotatable drive shaft extending therefrom, a main processor configured to control each drive component, a battery configured to power each drive component, an electrical receptacle, and a control interface(s) configured to control a functionality of the drive component. A sterile outer shell housing is configured to removably encase the power-pack to define a sterile barrier thus enabling use in a surgical environment without breaking sterility. The outer shell housing includes a coupler configured to transmit a rotation from the rotatable drive shaft through the outer shell housing, a control button(s) operatively positioned such that actuation of the control button actuates the control interface, and a pass-through connector configured to transmit electrical communications from the electrical receptacle through the outer shell housing.

First claim

What is claimed is:

1. A handheld electromechanical surgical device, comprising:
a non-sterile power-pack including:
at least one drive component, each drive component having a rotatable drive shaft extending therefrom;
a main processor coupled to the at least one drive component and configured to control each drive component;
a battery coupled to the main processor and the at least one drive component, the battery configured to power each drive component;
an electrical receptacle coupled to the main processor; and
at least one control interface coupled to the main processor, the at least one control interface actuatable to direct the main processor to control a functionality of at least one of the at least one drive component; and

a sterile outer shell housing configured to removably encase the power-pack, the sterile outer shell housing defining a sterile barrier between the power-pack and an exterior of the outer shell housing when encased about the power-pack to enable use thereof in a surgical environment without breaking sterility, the outer shell housing including:
a barrier plate assembly including:
a coupler configured to transmit a rotation from the rotatable drive shaft of each drive component through the outer shell housing, wherein the coupler includes a plurality of rotatable coupling shafts, each rotatable coupling shaft including a proximal end configured to operably couple to a respective rotatable drive shaft to receive rotative forces therefrom, and a distal end projecting from the outer shell housing;
at least one control button in operative registration with each of the at least one control interfaces such that actuation of the at least one control button actuates the at least one control interface in operative registration therewith; and
a pass-through connector configured to transmit electrical communications from the electrical receptacle through the outer shell housing, wherein the pass-through connector includes a proximal end configured to operably couple to the electrical receptacle, and a distal end projecting out of the outer shell housing.

2. The handheld electromechanical surgical device according to claim 1 , wherein the coupler transmits a rotation from the rotatable drive shaft of each drive component through the outer shell housing without breaking the sterile barrier.

3. The handheld electromechanical surgical device according to claim 1 , wherein the at least one control button actuates the at least one control interface in operative registration therewith without breaking the sterile barrier.

4. The handheld electromechanical surgical device according to claim 1 , wherein the pass-through connector transmits electrical communications from the electrical receptacle through the outer shell housing without breaking the sterile barrier.

5. The handheld electromechanical surgical device according to claim 1 , further including an adapter assembly selectively connectable to the outer shell housing in operable engagement with the coupler and the pass-through connector to enable a rotation from the rotatable drive shaft of each drive component to be transmitted through the outer shell housing to the adapter assembly and to enable electrical communications from the electrical receptacle to be transmitted through the outer shell housing to the adapter assembly.

6. The handheld electromechanical surgical device according to claim 1 , wherein the power-pack includes an inner housing enclosing each drive component, the main processor, and the battery, the inner housing including the at least one control interface and the electrical receptacle disposed thereon.

7. The handheld electromechanical surgical device according to claim 1 , wherein the at least one drive component is a motor.

8. A handheld electromechanical surgical device, comprising:
a non-sterile power-pack including at least one drive component having a rotatable drive shaft extending therefrom, a main processor coupled to each drive component, a battery coupled to the main processor and each drive component, an electrical receptacle coupled to the main processor, and at least one control interface coupled to the main processor;
a sterile outer shell housing configured to removably encase the power-pack, the sterile outer shell housing defining a sterile barrier between the power-pack and an exterior of the outer shell housing when encased about the power-pack to enable use thereof in a surgical environment without breaking sterility, the outer shell housing including;
a barrier plate assembly including:
a coupler configured to transmit an output from each drive component through the outer shell housing, wherein the coupler includes a plurality of rotatable coupling shafts supported on the barrier plate assembly, each rotatable coupling shaft including a proximal end configured to operably couple to a respective rotatable drive shaft to receive rotative forces therefrom, and a distal end projecting from the outer shell housing; and
a pass-through connector configured to transmit electrical communications from the electrical receptacle through the outer shell housing; and

at least one control button in operative registration with each of the at least one control interfaces such that actuation of the at least one control button actuates the at least one control interface in operative registration therewith;

an adapter assembly connected to the outer shell housing in operable engagement with the coupler and the pass-through connector to enable an output from each drive component to be transmitted through the outer shell housing to the adapter assembly and to enable electrical communications from the electrical receptacle to be transmitted through the outer shell housing to the adapter assembly; and
a loading unit connected to the adapter assembly, wherein the adapter assembly is configured to effect an operation of the loading unit in response to an output from at least one of the at least one drive component of the power-pack and to enable electrical communication between the electrical receptacle of the power-pack and the loading unit.

9. The handheld electromechanical surgical device according to claim 8 , wherein at least one of the loading unit and the adapter is selectively connectable.

10. The handheld electromechanical surgical device according to claim 8 , wherein the coupler transmits an output from each drive component through the outer shell housing without breaking the sterile barrier.

11. The handheld electromechanical surgical device according to claim 8 , wherein the at least one control button actuates the at least one control interface in operative registration therewith without breaking the sterile barrier.

12. The handheld electromechanical surgical device according to claim 8 , wherein the pass-through connector transmits electrical communications from the electrical receptacle through the outer shell housing without breaking the sterile barrier.

13. The handheld electromechanical surgical device according to claim 8 , wherein the at least one drive component includes a plurality of motors.

14. A handheld electromechanical surgical device, comprising:
a non-sterile power-pack including:
at least one drive component, each drive component having a rotatable drive shaft extending therefrom;
a main processor coupled to the at least one drive component and configured to control each drive component;
a battery coupled to the main processor and the at least one drive component, the battery configured to power each drive component;
an electrical receptacle coupled to the main processor; and
at least one control interf
