Abstract

A chassis for mounting a set of operating components of a power head of a surgical instrument is disclosed. The power head has a housing enabling access to an interior volume of the power head encompassed by the housing. The set of operating components have a proper configuration for alignment when mounted within the interior volume encompassed by the housing. The chassis is configured to provide the proper configuration for alignment of either an original or replacement set of operating components mounted on the chassis if the chassis and set of operating components are mounted within the interior volume of the housing. The chassis may be formed from metal and the housing formed from a polymer. The chassis may be configured to ground at least one electrical component.

Claims

1. A chassis for mounting a set of operating components of a power head of a hand-held surgical instrument,

the power head having a housing enabling access to an interior volume of the power head encompassed by the housing,

the set of operating components having a proper configuration for alignment when mounted within the interior volume encompassed by the housing,

wherein the chassis is configured to provide the proper configuration for alignment for either of:

the set of operating components mounted on the chassis if the chassis and set of operating components are mounted within the interior volume of the housing, and

a replacement set of operating components of the power head mounted on the chassis if the chassis and replacement set of operating components are mounted within the interior volume of the housing.

2. The chassis according to claim 1, wherein the chassis is formed from metal and the housing is formed from a polymer.

3. The chassis according to claim 2, wherein the set of operating components includes at least one electrical component and wherein the chassis is configured to enable electrical grounding of the at least one electrical component.

4. The chassis according to claim 1,

wherein the power head comprises a housing formed of two halves that are attached to each other at least two boss locators on each housing half, the boss locators disposed to align the two housing halves to each other,

the chassis comprising at least two boss locator ports that are configured and disposed to align with the at least two boss locators on each housing half.

5. The chassis according to claim 4,

wherein the power head comprises a firing rod that causes ejection of surgical fasteners via translation of the firing rod,

the chassis further comprising a slot formed therein, the slot configured and disposed as a datum for alignment of the firing rod with respect to the power head.

10. The power head according to claim 1,

wherein the power head comprises a housing formed of two halves that are attached to each other at least two boss locators on each housing half, the boss locators disposed to align the two housing halves to each other,

the chassis comprising at least two boss locator ports that are configured and disposed to align with the at least two boss locators on each housing half.

11. The power head according to claim 10,

wherein the power head comprises a firing rod that causes ejection of surgical fasteners via translation of the firing rod,

the chassis further comprising a slot formed therein, the slot configured and disposed as a datum for alignment of the firing rod with respect to the power head.

6. A power head for a hand-held surgical apparatus having

an interior volume formed within the power head;

and

a chassis for mounting a set of operating components of the power head,

the interior volume configured to receive the chassis.

7. The power head according to claim 6, the power head having a housing enabling access to the interior volume of the power head, the interior volume encompassed by the housing,

the set of operating components having a proper configuration for alignment when mounted within the interior volume encompassed by the housing,

wherein the chassis is configured to provide the proper configuration for alignment for either of:

the set of operating components mounted on the chassis if the chassis and set of operating components are mounted within the interior volume of the housing, and

a replacement set of operating components of the power head mounted on the chassis if the chassis and replacement set of operating components are mounted within the interior volume of the housing.

8. The power head according to claim 7, wherein the chassis is formed from metal and the housing is formed from a polymer.

9. The power head according to claim 8, wherein the set of operating components includes at least one electrical component and wherein the chassis is configured to enable electrical grounding of the at least one electrical component.
