Abstract
A joint and a corresponding method of creating a precision-fit joint, including creating a mating surface on a first joint component so that the mating surface includes one or more interfering features, connecting a second joint component with the mating surface such that the interfering feature is compressed, and heating the mating surface above a glass transition temperature or melting temperature of the mating surface, or otherwise treating the surface, so as to induce flow of material from the interfering feature to a area of relatively low pressure between the first joint component and the second joint component.
Claims7
A method of creating a precision-fit joint, comprising:
- creating a mating surface on a first joint component so that the mating surface includes one or more interfering features;
- connecting a second joint component with the mating surface such that the one or more interfering features are compressed, wherein the first joint component is a link for a chain comprising a plurality of links and the second joint component is a pin that connects the first joint component with another link in the chain;
- treating the mating surface so as to induce flow of material from the one or more interfering features to an area between the first joint component and the second joint component;
- and
- applying a stabilization mechanism that dampens vibrations between the first and second joint components, wherein the stabilizing mechanism stabilizes operation of a hydraulically controlled surgical device.
