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.
Claims32
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 interfering feature is compressed;
- and
- treating the mating surface so as to induce flow of material from the interfering feature to an area between the first joint component and the second joint component.
A method to create a precision-fit chain for an actuating device, comprising:
- creating a mating surface on a chain link so that the mating surface includes one or more interfering features;
- bringing a pin in contact with the mating surface on the chain link such that the one or more interfering features are compressed against the pin;
- and
- heating the pin to induce heating of the mating surface of the chain link above a glass transition temperature or melting temperature of the chain link so as to induce a flow of material from the interfering feature to a area of relatively low pressure between the chain link and the pin.
A precision-fit joint for a surgical device, comprising:
- a first joint component including a first mating surface, the first mating surface having at least one interfering feature;
- and
- a second joint component having a second mating surface mateable with the at least one interfering feature,
- wherein an interface between the first joint component and the second joint component produces a precision fit.
