Abstract
An ergonomic grip for an instrument or tool handle is provide which reduces upper extremity musculoskeletal disorder (MSDs) by increasing the grip cross-sectional area, reducing the grip force necessary to manipulate the instrument and increasing the grip comfort using an elastomeric gripping surface. Vibrations from the instrument or tool are reduced or eliminated to further reduce MSDs.
Claims26
In combination with a periodontal instrument having a handle portion and a working end portion, a removable ergonomic grip comprising:
- an elongated body member having a gripping surface, a pair of spaced-apart ends and a longitudinally extending internal aperture;
- said aperture receiving the handle portion of said periodontal instrument;
- a channel extending longitudinally from said first end to said second end and radially from said gripping surface to said aperture;
- and
- a contact adhesive along a circumference of said aperture;
- said body member comprising an elastomer having a shore hardness value in a range from approximately 20 to 80, and a cross-sectional diameter of approximately 0.5 inch to 2 inches.
In combination with a periodontal instrument having a handle portion and at least one working end portion, a removable ergonomic grip comprising:
- an elongated body member having a gripping surface, a pair of spaced-apart ends, and a longitudinally extending internal aperture, said aperture receiving the handle portion of said periodontal instrument;
- said body member having a cross-sectional diameter ranging from approximately 0.5 inch to 2 inches and comprising a first elastomer layer and a second elastomer layer having different shore hardness values.
A removable ergonomic grip for an elongated instrument handle comprising:
- an elastomeric sheet having first and second surfaces and a plurality of layers having shore hardness values ranging from approximately 20 to 80,
- a first open configuration, and
- a second closed configuration,
- whereby said sheet being adapted to wrap around said instrument handle in said second closed position with said first surface adjacent said instrument handle, said second surface forming an exterior gripping surface, and having a cross-sectional diameter ranging from approximately 0.5 to 2 inches in said second closed position.
