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:

a power-pack configured to selectively control a surgical accessory;

an outer shell housing including 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; and

a gasket located between the distal half-section and the proximal half-section of the outer shell housing, the gasket 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 environment outside the outer shell housing.

2. The electromechanical surgical device according to claim 1, wherein the distal half-section includes a proximal facing edge and the proximal half-section includes a distal facing edge, wherein in a first position, the proximal facing edge and the distal facing edge are spaced apart, and wherein in a second position, the proximal facing edge and the distal facing edge are approximated defining an interface therebetween.

3. The electromechanical surgical device according to claim 2, wherein the gasket is disposed at the interface defined between the distal facing edge of the proximal half-section of the outer shell housing, and the proximal facing edge of the distal half-section of the outer shell housing.

4. The electromechanical surgical device according to claim 2, wherein the proximal facing edge of the distal half-section of the outer shell housing defines a groove configured to receive the gasket.

5. The electromechanical surgical device according to claim 4, wherein the distal facing edge of the proximal half-section defines a protrusion configured to engage the gasket, wherein in the second position, at least a portion of the gasket is nested in the groove defined in the distal half-section when the proximal half-section and the distal half-section are approximated.

6. The electromechanical surgical device according to claim 5, wherein the gasket includes a reinforcing member configured to strengthen the seal between the distal half-section and the proximal half-section.

7. The electromechanical surgical device according to claim 6, wherein the reinforcing member is configured to be nested in the groove defined in the distal half-section of the outer shell housing when the proximal half-section and the distal half-section are approximated.

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

installing a gasket onto a proximal half-section of an outer shell housing of a hand-held electromechanical surgical device;

inserting a power-pack into a receiving cavity of the outer shell housing while maintaining a sterility of the outer shell housing; and

closing the outer shell housing by approximating the proximal half-section with a distal half-section of the outer shell housing to substantially entirely encase the power-pack within the outer shell housing, the gasket creating a seal between the distal half-section and the proximal half-section and providing a sterile barrier between the power-pack and an environment outside the outer shell housing.

9. The method according to claim 8, wherein installing the gasket onto the outer shell housing comprises:

removing a removable coating from a second side of the gasket; and

positioning the second side of the gasket on the proximal half-section of the outer shell housing.

10. The method according to claim 9, wherein installing the gasket onto the outer shell housing comprises:

inserting the gasket into a track defined in an insertion guide configured to guide the insertion of the power-pack into the receiving cavity of the outer shell housing;

positioning the insertion guide onto the proximal half-section of the outer shell housing such that the gasket is located on a distal facing edge of the proximal half-section of the outer shell housing; and

releasing the gasket from the track defined in the insertion guide such that when the insertion guide is removed from the proximal half-section of the outer shell housing, the gasket remains located on the distal facing edge of the proximal half-section of the outer shell housing.

11. A kit comprising:

a power-pack;

an electromechanical surgical device including an outer shell housing having 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; and

an insertion guide, the insertion guide locatable on the distal facing edge of the proximal half-section of the outer shell housing, the insertion guide configured to shield an outer surface of the outer shell housing from the power-pack when the power-pack is being inserted into the cavity of the outer shell housing.

12. The kit according to claim 11, wherein the insertion guide includes a body defining a track, the track configured to engage the distal facing edge of the proximal half-section of the outer shell.

13. The kit according to claim 12, further including a gasket, wherein the gasket is positioned in the track of the insertion guide, such that when the insertion guide is disposed on the distal facing edge of the proximal half-section of the outer shell housing, the gasket is disposed on the distal facing edge of the proximal half-section of the outer shell housing.

14. The kit according to claim 13, wherein the insertion guide includes a mechanical release configured to release the gasket from the track therein.
