Abstract:
A device (12) for coupling and decoupling a blade (14) and a handle (16) includes a housing (22). The housing (22) defines an interior chamber (28) and an exterior slot (24) adjacent the interior chamber (28). The exterior slot (24) is dimensioned to pass the blade (14) and is configured to receive a portion of the handle (16). The housing (22) defines a groove in the interior chamber (28) configured to retain the blade (14) in a ready configuration for coupling the blade (14) to the handle (16). The device (12) includes a pivot member (26) secured within the interior chamber (28) of the housing (22). The pivot member (26) is pivotable between an unlocked configuration and a locked configuration. The unlocked configuration of the pivot member (26) is configured to allow the blade (14) in the ready configuration to be coupled to the handle (16). The locked configuration of the pivot member (26) is configured to lock the blade (14) within the interior chamber (28).
Abstract:
A hand-held tool (10) has a handle having (11) a first end (12) configured for engaging a removable rotationally directional working tip (13). A sealing element (14) mountable in association with the handle and the working tip in known rotational alignment with the working tip seals the first end of the handle where it engages the working tip and provides tactile feedback to a user of the rotational direction of the working tip. The tactile feedback may also be achieved by one or more annular sleeves (30) formed of a flexible material mounted on the tool handle (11).
Abstract:
A surgical instrument (10, 100) configured to facilitate gripping and manual adjustment by a left-handed or righted-handed user. The surgical instrument includes a rod (11) having a first end (12a) attachable to a working end (13, 113) of the instrument via a mount (16). The rod has a second end (12b) coupled to a handle (14) having rotational directionality for gripping by a first hand of the user. The handle is rotatable about the rod so as to allow the user to adjust an angular displacement of the user's finger relative to the working end, and a locking member (20, 146) prevents rotation of the handle relative to the rod when the beveled indent is optimally located relative to the working end.
Abstract:
The invention provides an ergonomic handle for precision, surgical, and dental tools including electro-surgical devices and surgical devices used in microsurgery designed to facilitate the positioning of the user's hand grip comprising a longitudinally extending body (4) substantially oval in cross-section and being provided with four, substantially concave indentations positioned towards the proximal end of the handle, a first concave indentation (7) being provided along a top surface of the handle, second (5) and third (6) indentations being provided along lateral surfaces, and a fourth indentation (8) being provided along the bottom surface of the body respectively and positioned relative to each other to provide a contiguous interface respectively with the user's thumb, index finger and middle finger.
Abstract:
A finger-held instrument (25) having a handle (10) supporting a working tip (11, 31) on a mount (15) located at an end of the handle that is held proximate a working surface (43) during use, said handle being characterized by a projection (20) supported by or on said portion proximate the working tip and being dimensioned and shaped for supporting or shielding a user's finger (26a, 27a, 29a) and for exerting a contact force on the working surface so as to allow fine control of the working tip during use.
Abstract:
A knife (10) has a handle (15) with a mount (16) for affixing a removable blade (1 1). A concave surface (17) of the mount supports an elongate protrusion (18) for engaging a complementary slot (12) in the blade and reaches a landing (20) rearward of the tip that is exposed when the blade is mounted on the handle with a surface of the blade being completely supported by the concave surface. A channel (25) in the landing is dimensioned such that a rearmost part (26) thereof remains exposed when the blade is mounted on the handle. The blade is removed by inserting a curved lever (30) into the channel underneath a rearmost part of the blade and swiveling the lever so as to disengage the blade from the elongate protrusion.
