A set of surgical products which includes an attachment mechanism for modular surgical products. The set includes a plurality of first components and a plurality of second components. One of the first components and one of the second components are to be selected for engagement with each other. The components each include an indexing means including a key on the first components and a corresponding slot on the second components for mating with the key. The orientations of the keys and slots vary, so that only first components having a key orientation that is similar to and aligns with the slot orientation of a second component will properly mate together and so that first components will not properly align and mate with second components having slot orientations that are different from the respective key orientation.
A set of surgical products including a plurality of first components and a plurality of second components wherein one of the first components and one of the second components are selected for engagement with each other and wherein the first components each have a male peg extending therefrom with a key protruding from each respective peg and wherein the second components each have a female recess with a slot in each respective recess for corresponding engagement with one of the keyed pegs, and wherein the plurality of first components includes a first group of one or more first components in which the respective key is at a first orientation relative to the respective peg and a second group of one or more first components in which the respective key is at a second orientation different from the first orientation relative to the respective peg, and wherein the plurality of second components includes a first group of one or more second components in which the respective slot is at a first orientation relative to the respective recess, and a second group of one or more second components in which the respective slot is at a second orientation different from the first orientation relative to the respective recess, and wherein the first key orientation is aligned with and corresponds to the first slot orientation and the second key orientation is aligned with and corresponds to the second slot orientation, such that the first group of first components is adapted to properly align with and attach to only the first group of second components, while the second group of first components is adapted to properly align with and attach to only the second group of second components.
A set of surgical products including a plurality of first components and a plurality of second components wherein one of the first components and one of the second components are selected for engagement with each other and wherein the first components each have a key extending therefrom and wherein the second components each have a slot for corresponding engagement with one of the keys, and wherein the plurality of first components includes a first group of one or more first components in which the respective key is at a first orientation in relation to the respective first component and a second group of one or more first components in which the respective key is at a second orientation different from the first orientation in relation to the respective first component, and wherein the plurality of second components includes a first group of one or more second components in which the respective slot is at a first orientation in relation to the respective second component, and a second group of one or more second components in which the respective slot is at a second orientation different from the first orientation in relation to the respective second component, and wherein the first key orientation is aligned with and corresponds to the first slot orientation and the second key orientation is aligned with and corresponds to the second slot orientation, such that the first group of first components is adapted to properly align with and attach to only the first group of second components, while the second group of first components is adapted to properly align with and attach to only the second group of second components.
A set of surgical products including a plurality of provisional components and a plurality of rasp components, distinct from the provisional components, wherein one of the provisional components and one of the rasp components are selected for engagement with each other and wherein the provisional components each have a key extending therefrom and wherein the rasp components each have a slot for corresponding engagement with one of the keys and wherein the relative orientation of the respective key relative to each respective provisional component is not the same on all provisional components, and wherein the relative orientation of the respective slot relative to each respective rasp components is not the same on all rasp components, and wherein only provisional components having a key orientation that is similar to and aligns with the slot orientation of a rasp component, will properly align and mate together.
A set of surgical products including a plurality of provisional components and a plurality of rasp components, distinct from the provisional components, wherein one of the provisional components and one of the rasp components are selected for engagement with each other and wherein the provisional and rasp components have an attachment mechanism therebetween which includes an indexing means so that provisional components with a first indexing orientation will properly align with and attach to only rasp components with a like first indexing orientation and so that provisional components with a second indexing orientation will properly align with and attach to only rasp components with a like second indexing orientation and such that the first and second indexing orientations are different from each other and such that provisional components and rasp components having different indexing orientations will not properly align with each other for proper mating engagement.
A set of surgical products including a plurality of provisional components and a plurality of rasp components, distinct from the provisional components, wherein one of the provisional components and one of the rasp components are selected for engagement with each other and wherein the provisional components each have a male peg extending therefrom with a key protruding from each respective peg and wherein the rasp components each have a female recess with a slot in each respective recess for corresponding engagement with one of the keyed pegs, and wherein the plurality of provisional components includes a first group of one or more provisional components in which the respective key is at a first orientation relative to the respective peg and a second group of one or more provisional components in which the respective key is at a second orientation different from the first orientation relative to the respective peg, and wherein the plurality of rasp components includes a first group of one or more rasp components in which the respective slot is at a first orientation relative to the respective recess, and a second group of one or more rasp components in which the respective slot is at a second orientation different from the first orientation relative to the respective recess, and wherein the first key orientation is aligned with and corresponds to the first slot orientation and the second key orientation is aligned with and corresponds to the second slot orientation, such that the first group of provisional components is adapted to properly align with and attach to only the first group of rasp components, while the second group of provisional components is adapted to properly align with and attach to only the second group of rasp components.
A set of surgical products including a plurality of provisional components and a plurality of rasps components, distinct from the provisional components, wherein one of the provisional components and one of the rasp components are selected for engagement with each other and wherein the provisional components each have a key extending therefrom and wherein the rasp components each have a slot for corresponding engagement with one of the keys, and wherein the plurality of provisional components includes a first group of one or more provisional components in which the respective key is at a first orientation in relation to the respective provisional component and a second group of one or more provisional components in which the respective key is at a second orientation different from the first orientation in relation to the respective provisional component, and wherein the plurality of rasp components includes a first group of one or more rasp components in which the respective slot is at a first orientation in relation to the respective rasp component, and a second group of one or more rasp components in which the respective slot is at a second orientation different from the first orientation in relation to the respective rasp component, and wherein the first key orientation is aligned with and corresponds to the first slot orientation and the second key orientation is aligned with and corresponds to the second slot orientation, such that the first group of provisional components is adapted to properly align with and attach to only the first group of rasp components, while the second group of provisional components is adapted to properly align with and attach to only the second group of rasp components.
