Abstract

A surgical device is provided. The surgical device includes: a jaw assembly comprising a first jaw and a second jaw moveable relative to the first jaw and an elongated body removably coupled to a proximal end of the jaw assembly. The elongated body includes an actuation bar movable upon engagement of the jaw assembly with the elongated body to secure the jaw assembly thereto; a release button coupled to the actuation bar such that the release button is movable by the actuation bar upon engagement of the jaw assembly with the elongated body and the release button is configured to move the actuation bar to allow for removal of the jaw assembly from the elongated body; and a lockout button in mechanical cooperation with the release button, the lockout button configured to prevent actuation of the release button.

Claims

1. A surgical device, comprising:

a jaw assembly comprising a first jaw and a second jaw moveable relative to the first jaw; and

an elongated body removably coupled to a proximal end of the jaw assembly, the elongated body comprising;

an actuation bar, wherein engagement of the jaw assembly to the elongated body moves the actuation bar thereby securing the elongate body to the jaw assembly;

a release button coupled to the actuation bar, wherein movement of the actuation bar due to the engagement of the jaw assembly with the elongate body moves the release button and the release button is configured to move the actuation bar to allow for removal of the jaw assembly from the elongated body; and

a lockout button in mechanical cooperation with the release button, the lockout button configured to prevent actuation of the release button.

2. The surgical device of claim 1, further comprising:

a handle assembly removably coupled to a proximal end of the elongated body and comprising at least one motor mechanically coupled to the jaw assembly.

3. The surgical device of claim 1, wherein the release button is configured to move along a first longitudinal axis.

4. The surgical device of claim 3, wherein the lockout button is configured to move along a second longitudinal axis that is transverse to the first longitudinal axis.

5. The surgical device of claim 4, wherein the release button comprises a resilient arm extending therefrom and a tab coupled to the resilient arm.

6. The surgical device of claim 5, wherein the lockout button comprises a base having a first surface feature configured to engage the tab.

7. The surgical device of claim 6, wherein the first surface feature has a substantially arcuate shape having a convex side and a concave side.

8. The surgical device of claim 7, wherein upon movement of the release button in response to the engagement of the jaw assembly with the elongated body the tab engages the concave side of the surface feature.

9. A surgical device, comprising:

a jaw assembly comprising a first jaw and a second jaw moveable relative to the first jaw; and

an elongated body removably coupled to a proximal end of the jaw assembly, the elongated body comprising;

an actuation bar, wherein engagement of the jaw assembly to the elongated body moves the actuation bar thereby securing the elongate body to the jaw assembly;

a release button coupled to the actuation bar, wherein movement of the actuation bar due to the engagement of the jaw assembly with the elongate body moves the release button; and

a lockout button movable from a home position to a release position, wherein in the home position the lockout button engages the release button being moved by the actuation bar to prevent actuation thereof and in the release position the lockout button unlocks the release button such that the release button is actuatable to move the actuation bar to allow for removal of the jaw assembly from the elongated body.

10. The surgical device of claim 9, further comprising:

a handle assembly removably coupled to a proximal end of the elongated body and comprising at least one motor mechanically coupled to the jaw assembly.

11. The surgical device of claim 9, wherein the release button is configured to move along a first longitudinal axis.

12. The surgical device of claim 11, wherein the lockout button is configured to move along a second longitudinal axis that is transverse to the first longitudinal axis.

13. The surgical device of claim 12, wherein the release button comprises a resilient arm extending therefrom and a tab coupled to the resilient arm.

14. The surgical device of claim 13, wherein the lockout button comprises a base having a first surface feature configured to engage the tab.

15. The surgical device of claim 14, wherein the first surface feature has a substantially arcuate shape having a convex side and a concave side.

16. The surgical device of claim 15, wherein upon movement of the release button in response to the engagement of the jaw assembly with the elongated body the tab engages the concave side of the surface feature.

17. A surgical device adapter for coupling a jaw assembly comprising a first jaw and a second jaw moveable relative to the first jaw to a handle assembly, the adapter comprising:

an elongated body removably coupled to a proximal end of the jaw assembly at a distal end thereof and to the handle assembly at a proximal end thereof;

an actuation bar, wherein engagement of the jaw assembly to the elongated body moves the actuation bar thereby securing the elongate body to the jaw assembly;

a release button coupled to the actuation bar, wherein movement of the actuation bar due to the engagement of the jaw assembly with the elongate body moves the release button; and

a spring-loaded lockout button movable from a home position to a release position, wherein in the home position the lockout button engages the release button being moved proximally by the actuation bar to prevent actuation thereof and in the release position the lockout button unlocks the release button such that the release button is actuatable to move the actuation bar to allow for removal of the jaw assembly from the elongated body.

18. The surgical device adapter of claim 17, wherein the release button is configured to move along a first longitudinal axis and the lockout button is configured to move along a second longitudinal axis that is transverse to the first longitudinal axis.

19. The surgical device adapter of claim 18, wherein the release button comprises a resilient arm extending therefrom and a tab coupled to the resilient arm and the lockout button comprises a base having a first surface feature configured to engage the tab.

20. The surgical device adapter of claim 19, wherein the first surface feature has a substantially arcuate shape having a convex side and a concave side, such that upon movement of the release button in response to the engagement of the jaw assembly with the elongated body the tab engages the concave side of the surface feature.
