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.

First claim

What is claimed is:

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.
