Abstract

A removable component configured for insertion into an internal compartment of a surgical instrument is provided including a housing defining first and second ends, a grasping member, and a biasing member. The grasping member is operably coupled to the housing at the second end thereof and is movable relative to the housing between a presented position, wherein at least a portion of the grasping member is spaced-apart from the second end of the housing, and a stored position, wherein the grasping member is approximated relative to the second end of the housing. The biasing member is disposed between the grasping member and the second end of the housing and is configured to bias the grasping member towards the presented position. Systems including a surgical instrument and such a removable component and methods of assembling a surgical instrument using the same are also provided.

Claims

1. A removable component configured for insertion into an internal compartment of a surgical instrument, the removable component comprising:

a housing defining a first end and a second end;

a grasping member including a finger ring portion, at least one hinge leg, and an extension portion interconnecting the finger ring portion and the at least one hinge leg, the grasping member pivotably coupled to the housing at the second end of the housing via the at least one hinge leg, the grasping member pivotable about the at least one hinge leg and relative to the housing between a presented position, wherein at least a portion of the grasping member is spaced-apart from the second end of the housing, and a stored position, wherein the grasping member is approximated relative to the second end of the housing; and

a biasing member disposed between the grasping member and the second end of the housing, the biasing member configured to bias the grasping member towards the presented position.

2. The removable component according to claim 1, wherein the removable component is a battery pack, the battery pack including at least one electrical contact disposed at the first end of the removable component.

3. The removable component according to claim 1, wherein the housing includes a hinge block defining at least one lumen, the at least one hinge leg pivotably disposed within the at least one lumen to enable pivoting of the grasping member relative to the housing.

4. The removable component according to claim 1, wherein the housing includes a retainer block, and wherein the biasing member is partially-disposed within the retainer block.

5. The removable component according to claim 4, wherein, an exposed portion of the biasing member extends from the retainer block, the exposed portion of the biasing member configured to contact the finger ring portion of the grasping member upon pivoting of the grasping member towards the stored position to bias the grasping member against further movement towards the stored position.

6. The removable component according to claim 4, wherein, in the stored position of the grasping member, the finger ring portion is disposed about the retainer block in surrounding relation therewith.

7. A surgical system, comprising:

a surgical instrument defining an internal compartment and a door movable between an open position and a closed position for providing access to the internal compartment and closing the internal compartment; and

a removable component, including;

a housing defining a first end and a second end, the housing configured for insertion into the internal compartment of the surgical instrument led by the first end thereof;

a grasping member including a finger ring portion, at least one hinge leg, and an extension portion interconnecting the finger ring portion and the at least one hinge leg, the grasping member pivotably coupled to the housing at the second end of the housing via the at least one hinge leg, the grasping member pivotable about the at least one hinge leg and relative to the housing between a presented position, wherein at least a portion of the grasping member is spaced-apart from the second end of the housing, and a stored position, wherein the grasping member is approximated relative to the second end of the housing; and

a biasing member disposed between the grasping member and the second end of the housing, the biasing member configured to bias the grasping member towards the presented position,

wherein, upon moving the door of the surgical instrument to the closed position with the removable component disposed within the internal compartment, the door urges the grasping member towards the stored position against the bias of the biasing member.

8. The surgical system according to claim 7, wherein the surgical instrument further includes a lock assembly configured to lock the door in the closed position upon movement of the door to the closed position.

9. The surgical system according to claim 8, wherein, with the door locked in the closed position with the removable component disposed within the internal compartment, the biasing member is disposed in a loaded state.

10. The surgical system according to claim 8, wherein the lock assembly further includes a release button, the release button selectively depressible to unlock the door from the closed position.

11. The surgical system according to claim 10, wherein, upon depression of the release button to unlock the door, the grasping member is configured to bias the grasping member towards the presented position, thereby urging the door towards the open position.

12. The surgical system according to claim 7, wherein the removable component is a battery pack configured to provide power to the surgical instrument.

13. The surgical system according to claim 12, wherein the battery pack includes at least one electrical contact disposed at the first end of the removable component, the at least one electrical contact configured to electrically couple to a corresponding at least one electrical contact of the surgical instrument upon insertion of the removable component into the internal compartment for providing power to the surgical instrument.

14. The surgical system according to claim 7, wherein the finger ring portion is configured to facilitate manipulation of the removable component.
