Abstract: A reusable surgical implement is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable rigid, and optionally flexible material to enable the implant to conform to the desired use for the implement in a surgical procedure. The material forming the enclosure is also stretchable and flexible to accommodate the configuration and/or any flexing of the core, and is biologically inert to enable the implant to be sterilized after use for use in subsequent surgical procedures while protecting the material forming the core. The enclosure can be molded around the core in separate portions or components using multiple molding steps to form an enclosure with the desired attributes.
Abstract: This invention relates to a fastener driving device including a variable ratio gear mechanism that enables the ratio of the rotation of the handle to the rotation of a driving bit extending from the handle to be varied to allow the bit to rotate at different speeds from the handle. The device includes a gear mechanism disposed within a housing for the device that includes a locking member. The locking member can be engaged with the gear mechanism to lock the gear mechanism in a configuration for a 1:1 gear ratio. The locking member can be moved with regard to the gear mechanism to provide an increased gear ratio for the gear mechanism when desired.

Abstract: 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.

Abstract: A reusable surgical implement is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable flexible material to enable the implement, which can be any suitable device such as a reusable surgical trial implant, rod template or flex driver, among others, to be bent to conform to the desired shape for an actual implant to be placed in the location of the implement. The material forming the enclosure is also flexible to accommodate the flexing of the core, and is biologically inert to enable the implement to be sterilized after use for use in subsequent surgical procedures.

Abstract: A handle for a tool is provided that is formed of a core positioned within a sleeve of a temperature resistant material to form a handle with a space between the core and the sleeve. The core can be formed by machining a metal material while the sleeve and an optional skin positioned on the sleeve can be molded. The materials forming the sleeve and skin, and the space formed between the core and sleeve, create a handle that can be adapted to form a variety of different tools with different mechanisms located in the core that also has improved heat transfer characteristics for sterilization purposes.
Abstract: A process for producing molded products having portions formed with two separate materials is provided. The process involves forming a first component over a structural core in a first step, and forming a second component that is secured to the first component and the core in a second step. The second component can be formed directly over the first component or can be secured thereto after formation. The first and second components can additionally be formed with indicia thereon, or with recesses within which inserts containing the desired indicia can be positioned. Additionally, the first component can be formed with a ridge disposed on a projection formed on the first component that effectively seals off a portion of the first component when the second component is formed around the core and the first component to ensure the portion of the first component surrounded by the ridge remains visible after formation of the second component.

Abstract: A tool including selectively operable torque-limiting mechanism is provided. The tool includes a housing, a torque-limiting mechanism disposed within the housing and including a first gear engaged with the housing and including a number of first recesses, a second gear rotatably disposed within the housing adjacent the first gear and including a number of second recesses, a number of bearings disposed between the first gear and the second gear partially within the first recesses and partially within the second recesses, and a variable force-applying assembly engaged with the first gear opposite the second gear, a drive body engaged with the second gear and extending outwardly from the housing, and a cover disposed around the housing and selectively engaged with the drive body to control the operation of the torque-limiting mechanism.
