CONTROL MODULE FOR A POWERED SURGICAL TOOL, THE MODULE INCLUDING A SHELL HAVING ACTIVE SEALS DISPOSED AROUND THE CONDUCTIVE PINS THAT EXTEND INTO THE SHELL
First Claim
1. A control module for regulating the operation of a powered surgical tool, said control module including:
- a shell, said shell configured for attachment to a powered surgical tool and said shell being formed with at least one opening;
a circuit disposed in said shell for regulating operation of a power generating unit integral with the powered surgical tool;
at least one conductive pin that extends through the at least one opening of said shell for establishing an electrical connection between said power generating unit and said circuit; and
a seal assembly disposed in said at least one opening of said shell, said seal including;
a first stop disposed in the at least one opening around said pin, said first stop extending to an inner surface of said shell that defines the shell opening;
a second stop disposed in the at least one opening around said pin said second stop extending to the inner surface of said shell that defines the shell opening, said second stop being spaced away from said first stop;
a seal unit disposed in the at least one opening around said conductive pin and between said first and second stops, said seal including;
a boot, said boot shaped to have an inner skirt that extends around a section of said conductive pin that that extends through the shell opening;
an outer skirt that disposed around said pin adjacent the inner surface of said shell that defines the shell opening; and
a base that extends between said skirts; and
at least one biasing member separate from said boot located between said skirts that biases the outer skirt against the shell inner surface or biases the inner skirt against said pin.

Abstract
A control module for a powered surgical tool. The module includes a shell. Internal to the shell is a circuit for controlling the power generating unit of the tool with which the module is associated. Conductive pins extend through the shell to provide electrical connections to the components within the shell. Active seals are disposed around the conductors and the inner walls of the shell that define the openings in which the pins are seated. Each active seal include an inner and outer skirt. A biasing component disposed between the skirts urges the inner skirt against the section of the conductive pin seated in the opening. The biasing component also urges the outer skirt against the adjacent opening-defining inner wall of the shell. The active seal functions as a barrier between the conductive pin and the adjacent inner wall of the shell.

12. A control module for regulating the operation of a powered surgical tool, said control module including
a shell, said shell, shaped to be formed with at least one opening, the at least one opening being defined by an inner wall of said shell: -
a circuit disposed in said shell for regulating operation of said power generating unit; at least one conductive pin that extends through the at least one opening of said shell for establishing an electrical connection between said power generating unit and said circuit; a boot disposed in the at least one opening of said shell so as to extend around a section of said conductive pin disposed in said opening, said boot having;
an inner skirt that is disposed against said at least one pin; and
an outer skirt that is connected to and extends outwardly from said inner skirt, said outer skirt extending towards the inner wall of said shell that defines shell opening;a spring located between said inner and outer of skirts of said boot that at least one of;
biases said inner skirt against said at least one conductive pin;
or biases said outer skirt against the inner wall of said shell;first and second stops that extend inwardly from the inner wall of said shell, said stops being spaced apart from each other and said boot and said spring being disposed between said stops, wherein said stops are mounted to said shell to prevent longitudinal movement of said boot and said spring beyond said stops. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
