Abstract: A mount for supporting a cylindrical bottle includes an annular core having an inner side surface defining a hollow opening, an outer side surface, a top surface and a base surface. A plurality of pliable ribs each at least partially encircles the annular core so as to overlap the outer side surface, the top surface and the base surface such that at least an upper end of each rib where it overlaps the top surface extends into the hollow opening. The mount may be used in conjunction with a collar having a body portion for surrounding the bottleneck and defining along at least a portion of an axis thereof a substantially quadrilateral cross-section having in each corner thereof a respective arcuate recess.

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 passing tray for surgical instruments includes a holder having a base portion, opposing side portions open at a first end and an end portion. A sliding member having front and rear edges is slidably supported within the holder. At least one support member projects upwardly from a surface of the sliding member toward its front edge, and an actuator projects upwardly from the surface of the sliding member intermediate the front and rear edges thereof and has front and rear surfaces facing toward the front and rear edges of the sliding member, respectively. In use an elongated surgical instrument may be retained transversely between opposing surfaces of the support member and the open first end of the holder under force of the actuator.

Abstract: A knife (10) has a handle (15) with a mount (16) for affixing a removable blade (11). 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.

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 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 being provided along a top surface of the handle, second and third indentations being provided along lateral surfaces, and a fourth indentation 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: The invention provides an ergonomic, gripping sleeve device for precision instruments, comprising a tubular product open at opposite ends thereof and attachable as a sleeve close to a proximal end of said precision instrument having a working tip at its proximal end, said sleeve device being designed to facilitate the positioning of the user's hand grip, said sleeve device comprising a longitudinally extended tubular body substantially hollow and oval in cross-section and being provided on its outer surface with four, substantially concave indentations, a first concave indentation being provided along a top surface of said sleeve device, second and third indentations being provided along lateral surfaces, and a fourth indentation being provided along the bottom surface of said sleeve device, characterized in that the surface of the top of said sleeve device is contoured such that extending from its distal end toward its proximal end and approaching said proximal end there is provided said concave indentation

Abstract: An ergonomic writing instrument designed to facilitate the positioning of the user's hand grip. The writing instrument comprises a longitudinally extending body 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 being provided along a top surface of the handle, second and third indentations being provided along lateral surfaces, and a fourth indentation being provided along the bottom surface of the body, characterized in that the surface of the top of the handle is contoured such that extending from its distal end toward its proximal end and approaching the proximal end there is provided the concave indentation which extends and merges into an elevated ridge-like surface support which tapers angularly towards the proximal end of the handle.
