Abstract

A surgical instrument includes a housing, an elongated portion, and a loading unit. The elongated portion extends distally from the housing, defines a longitudinal axis, and includes an electrical contact. The loading unit is configured to releasably engage the elongated portion. The loading unit includes an electronic component, a proximal portion including an electrical contact in electrical communication with the electronic component, and an end effector coupled to the proximal portion and configured to manipulate tissue. Engagement between the elongated portion and the loading unit causes the electrical contact of the elongated portion to engage the electrical contact of the loading unit thereby electrically connecting the elongated portion and the loading unit.

Claims (27)

1. A surgical instrument configured to releasably engage a loading unit having an electronic component, the surgical instrument comprising:

a powered assembly;

an elongated portion coupled to the powered assembly, defining a central longitudinal axis, and including an outer wall; and

an electrical contact disposed within the outer wall of the elongated portion, at least a portion of the electrical contact being movable radially inward and outward relative to the central longitudinal axis, the electrical contact having at least three segments including a first segment, a second segment, and a third segment, the second segment disposed distally of and radially inward from the first segment, and the third segment disposed distally of the second segment and disposed at an angle relative to the central longitudinal axis,

wherein the electrical contact is configured to communicate with the electronic component of the loading unit when the surgical instrument is engaged with the loading unit.

2. The surgical instrument according to claim 1 , wherein at least a portion of the first segment of the electrical contact is parallel to the central longitudinal axis.

3. The surgical instrument according to claim 2 , wherein at least a portion of the second segment is parallel to the central longitudinal axis.

4. The surgical instrument according to claim 1 , wherein the electrical contact is made from sheet metal.

5. The surgical instrument according to claim 1 , further including at least one of a processor or a storage unit disposed in electrical communication with the electrical contact.

6. The surgical instrument according to claim 1 , wherein the third segment of the electrical contact is disposed at an angle with respect to the first segment.

7. The surgical instrument according to claim 6 , wherein at least a portion of the first segment is parallel to at least a portion of the second segment.

8. The surgical instrument according to claim 6 , wherein at least a portion of the first segment, and at least a portion of the second segment are parallel to the central longitudinal axis.

9. The surgical instrument according to claim 1 , wherein the third segment of the electrical contact is linear.

10. A surgical instrument configured to releasably engage a loading unit having an electronic component, the surgical instrument comprising:

an elongated portion defining a central longitudinal axis, and including an outer wall; and

an electrical contact disposed within the outer wall of the elongated portion, at least a portion of the electrical contact being movable radially inward and outward relative to the central longitudinal axis, the electrical contact having at least three segments including a first segment, a second segment, and a third segment, the second segment disposed distally of and radially inward from the first segment, the second segment disposed at an angle relative to the central longitudinal axis, and the third segment disposed distally of the second segment,

wherein the electrical contact is configured to communicate with the electronic component of the loading unit when the surgical instrument is engaged with the loading unit.

11. The surgical instrument according to claim 10 , wherein at least a portion of the first segment of the electrical contact is parallel to the central longitudinal axis.

12. The surgical instrument according to claim 11 , wherein at least a portion of the third segment is parallel to the central longitudinal axis.

13. The surgical instrument according to claim 10 , wherein the electrical contact is made from sheet metal.

14. The surgical instrument according to claim 10 , further including at least one of a processor or a storage unit disposed in electrical communication with the electrical contact.

15. The surgical instrument according to claim 10 , wherein the third segment of the electrical contact is parallel to the first segment.

16. The surgical instrument according to claim 10 , wherein the second segment of the electrical contact interconnects the first segment and the third segment.

17. The surgical instrument according to claim 10 , wherein the third segment of the electrical contact is linear.

18. The surgical instrument according to claim 10 , wherein the at least three segments of the electrical contact includes a fourth segment, the fourth segment disposed distally of the third segment.

19. The surgical instrument according to claim 18 , wherein a distal portion of the fourth segment of the electrical contact is positioned radially outward from a proximal portion of the fourth segment.

20. The surgical instrument according to claim 19 , wherein a distal portion of the second segment of the electrical contact is positioned radially inward from a proximal portion of the second segment.
