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 ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 3) The hand-held electromechanical surgical device according to claim 3, wherein the gasket is disposed between the projection and the groove. ### Claim 5 (depends on 1) The hand-held electromechanical surgical device according to claim 1, wherein the reinforcing member is a rod. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 1) The hand-held electromechanical surgical device according to claim 1, wherein the gasket includes anti-microbial substances. ### Claim 10 (depends on 1) The hand-held electromechanical surgical device according to claim 1, wherein the gasket has an H-shaped cross-sectional profile. ### Claim 11 (depends on 1) 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. ### Claim 12 (depends on 11) The hand-held electromechanical surgical device according to claim 11, wherein the power-pack includes: a battery;
