Abstract

A hand-held electromechanical surgical device is configured to selectively connect with a surgical accessory. The surgical device includes a power-pack, an outer shell housing, and a gasket. The power-pack is configured to selectively control a surgical accessory. The outer shell housing includes a distal half-section and a proximal half-section, the distal half-section and the proximal half-section together defining a cavity configured to selectively encase substantially the entire power-pack therein. The gasket is located between the distal half-section and the proximal half-section of the outer shell housing. The gasket is configured to create a seal between the distal half-section and the proximal half-section and to provide a sterile barrier between the power-pack and an outside environment outside the outer shell housing.

Claims

1. A hand-held electromechanical surgical device, comprising:

an outer shell housing including;

a distal section having a proximal-facing edge defining a mating feature; and

a proximal section having a distal-facing edge defining a mating feature configured to engage the mating feature of the distal section, the mating feature of the proximal section or the mating feature of the distal section including a groove, the distal and proximal sections together defining a cavity configured to selectively encase a power-pack therein; and

a gasket located between the distal and proximal sections of the outer shell housing and including;

a body configured to compress between the distal-facing edge of the proximal section and the proximal-facing edge of the distal section; and

a reinforcing member disposed within the body and configured for receipt in the groove, wherein the gasket is configured to create a seal between the distal and proximal sections of the outer shell housing and to provide a sterile barrier between the power-pack and an environment outside the outer shell housing.

2. The hand-held electromechanical surgical device according to claim 1, wherein the mating feature of the distal section extends at least partially around a periphery of the proximal-facing edge of the distal section, and the mating feature of the proximal section extends at least partially around a periphery of the distal-facing edge of the proximal section.

3. The hand-held electromechanical surgical device according to claim 1, wherein the mating feature of the distal section is one of the groove or a projection, and the mating feature of the proximal section is the other of the groove or the projection.

4. The hand-held electromechanical surgical device according to claim 3, wherein the gasket is disposed between the projection and the groove.

5. The hand-held electromechanical surgical device according to claim 1, wherein the reinforcing member is a rod.

6. The hand-held electromechanical surgical device according to claim 1, wherein the reinforcing member is fabricated from a material having a hardness greater than a hardness of a material of the body.

7. The hand-held electromechanical surgical device according to claim 1, wherein the gasket is disposed at an interface defined between the distal-facing edge of the proximal section and the proximal-facing edge of the distal section.

8. The hand-held electromechanical surgical device according to claim 1, wherein the distal and proximal sections of the outer housing shell are movable relative to one another between a first position, in which the proximal-facing edge of the distal section and the distal-facing edge of the proximal section are spaced apart from one another, and a second position, in which the proximal-facing edge and the distal-facing edge are approximated to compress the gasket therebetween.

9. The hand-held electromechanical surgical device according to claim 1, wherein the gasket includes anti-microbial substances.

10. The hand-held electromechanical surgical device according to claim 1, wherein the gasket has an H-shaped cross-sectional profile.

11. The hand-held electromechanical surgical device according to claim 1, further comprising a power-pack configured to be received in the cavity of the outer housing shell.

12. The hand-held electromechanical surgical device according to claim 11, wherein the power-pack includes:

a battery;

control circuitry; and

at least one motor electrically connected to the control circuitry and the battery.

13. The hand-held electromechanical surgical device according to claim 12, wherein the power-pack further includes an inner handle housing defining a cavity, the cavity of the inner handle housing having the battery, the control circuitry, and the at least one motor situated therein.

14. A method of assembling a hand-held electromechanical surgical device, comprising:

inserting a power-pack into an outer shell housing while maintaining a sterility of at least an outer surface of the outer shell housing; and

closing the outer shell housing by approximating a proximal section of the outer shell housing and a distal section of the outer shell housing to encase the power-pack within a cavity cooperatively defined by the proximal and distal sections of the outer shell housing, thereby compressing a gasket between a groove or a projection of a distal-facing edge of the proximal section and the other of the groove or the projection of a proximal-facing edge of the distal section.

15. The method according to claim 14, further comprising engaging a first side of the gasket with the projection to urge at least a second side of the gasket into the groove.

16. The method according to claim 14, further comprising positioning a reinforcing member of the gasket in the groove, wherein the reinforcing member is disposed within a compressible body of the gasket.

18. The method according to claim 14, wherein inserting the power-pack into the outer shell housing includes passing the power-pack through an insertion guide coupled to the distal-facing edge of the proximal section, the insertion guide covering the distal-facing edge of the proximal section.

19. The method according to claim 18, further comprising detaching the insertion guide from the proximal section of the outer shell housing after the power-pack is disposed within the proximal section of the outer shell housing.

20. The method according to claim 19, wherein the outer shell housing is closed after the insertion guide is detached from the proximal section of the outer shell housing.

21. The method according to claim 20, further comprising removing a film covering a distal-facing side of the gasket after the insertion guide is detached from the proximal section of the outer shell housing.

23. A hand-held electromechanical surgical device, comprising:

an outer shell housing including;

a distal section having a proximal-facing edge defining a mating feature; and

a proximal section having a distal-facing edge defining a mating feature configured to engage the mating feature of the distal section, the distal and proximal sections together defining a cavity configured to selectively encase a power-pack therein; and

a gasket having an H-shaped cross-sectional profile and located between the distal and proximal sections of the outer shell housing, wherein the gasket is configured to create a seal between the distal and proximal sections of the outer shell housing and to provide a sterile barrier between the power-pack and an environment outside the outer shell housing.
