Electronic torque wrench
A torque wrench for use in driving fasteners is provided. The wrench includes an electronics unit disposed within a housing engaged with the body of the wrench that is capable of sensing and measuring the torque applied to a fastener by the wrench and providing an output of the level of torque to the user. The data sensed by the electronics unit can be utilized to provide feedback to the user regarding the operation of the wrench, and to monitor the overall operation of the wrench for calibration purposes, among other functions. During use, the wrench can provide the user with visual, audible and tactile feedback regarding the operation of the device relative to stored maximum torque values stored in the electronics unit. The housing for the electronics unit can be formed to be a single use component of the tool or can be designed for multiple uses with a configuration that can be engaged with cradles forming the body of the wrench having various different configurations.
1. A driving tool comprising:
a) a shaft engageable with a fastener;
b) a housing capable of being subjected to temperatures and pressures associated with medical sterilization procedures and including an electronics unit including a torque measurement system operably connected to the shaft and operable to measure the torque exerted though the shaft on a fastener; and
c) a body defining a sleeve therein, wherein the housing is positioned at least partially within the sleeve.
2. The tool of claim 1 wherein the housing is removably positioned within the sleeve.
3. The tool of claim 1 further comprising a power source operably connected to the electronics unit.
4. The tool of claim 3 wherein the power source is positioned within the housing.
5. The tool of claim 4 wherein the power source is positioned within the body.
6. The tool of claim 3 wherein the housing is not fully inserted into the sleeve.
7. The tool of claim 6 wherein the housing includes lighted indicators disposed within the housing at a location outside of the sleeve.
8. The tool of claim 6 wherein the housing includes lighted indicators disposed within the housing alignable with a window in the body.
9. The tool of claim 1 wherein the housing is affixed to the shaft.
10. The tool of claim 1 wherein the body is affixed to the shaft.
11. A method of driving a fastener into a substrate comprising the steps of:
a) providing the tool of claim 1 ; and
b) engaging a fastener with the tool.
