Patent number: 10292839Abstract: The present disclosure relates to a switchable terminal device that includes a first digit having a distal end and a proximal end, a second digit moveably attached to the first digit by a first connector such that the second digit reversibly rotates around the first connector and substantially within a plane, and a lever guide having a first portion and a second portion, the lever guide attached to the second digit at least by the first connector passing through the lever guide at an angle about perpendicular to the plane. The switchable terminal device also includes a lever having a proximal end and a distal end with the proximal end of the lever moveably attached to the first portion of the lever guide by a second connector, a third connector attached near the distal end of the first digit, and an elastic cord that includes a first segment having a first end, and a second segment having a second end.Type: GrantFiled: January 23, 2017Date of Patent: May 21, 2019Assignee: Invisible Hand Enterprises, LLCInventor: Bradley Delton Veatch

Patent number: 10045865Abstract: This disclosure relates to the field of prosthetics, more specifically to a pinless anthropomorphic hinge or joint, and a digit comprising one or more phalanges connected by and articulating around pinless joints, whereby the joints provide compliant movement in more than one plane. This disclosure also relates to modular prosthetic systems comprising multiple digits, in particular for partial-hand replacements.Type: GrantFiled: September 26, 2016Date of Patent: August 14, 2018Assignee: INVISIBLE HAND ENTERPRISES, LLCInventor: Bradley Delton Veatch

Patent number: 9931229Abstract: The present invention is a switchable gripping terminal device that can be switched from a voluntary open prehension mode to a voluntary closed prehension mode, at will by the user. In an embodiment of the present invention, the terminal device may comprise a movable digit attached to a fixed digit, whereby the user can actuate the movable digit, such that the movable digit rotates relative to the fixed digit. The terminal device may comprise a lever, which enables the user to switch from a first mode, voluntary open (VO), to a second mode, voluntary closed (VC). This switchable biasing means, allows the user to decide the prehension mode, and easily switch the mode at will, according to the circumstances.Type: GrantFiled: June 25, 2017Date of Patent: April 3, 2018Assignee: INVISIBLE HAND ENTERPRISES, LLCInventor: Bradley Delton Veatch

Patent number: 8414658Abstract: An upper extremity prosthetic device is provided that comprises three main components, namely, an arm cuff, a forearm section and a distal connector. The arm cuff is adjustable to accommodate lower arms of different sizes. The forearm section may be constructed in certain limited sizes to accommodate different sized forearm residual limbs. The distal connector is designed to connect to any of the forearm section configurations, and the distal connector enables any terminal device to be attached to the connector. The components may be mixed and matched in various combinations to fit the physical dimensions of virtually any amputee. The interchangeable parts will accommodate a wide range of residual limb geometries, overall sizes and lengths. Embodiments of the present invention minimize the need for time and resource-intensive customized fitting and create an affordable, relatively low-cost prosthetic interface.Type: GrantFiled: October 1, 2009Date of Patent: April 9, 2013Assignee: Invisible Hand Enterprises, LLCInventors: Alwyn P. Johnson, Bradley D. Veatch, Norman J. Haberkorn, Ronald Krenzel

Patent number: 8052761Abstract: A voluntary opening prosthetic split hook terminal device is provided with an adjustable pinch force, functional grasping contours and illumination capabilities. Embodiments of the present invention include a tensioning mechanism that permits adjustment of the tension of a spring member to increase or decrease the pinching force of the device. The tensioning mechanism may be repositioned among multiple positions to vary the tension in a spring member. Movement of the tensioning mechanism utilizes principles of mechanical leverage in a way such that the force applied by the spring member does not need to be directly opposed in order to reposition the tensioning mechanism and the tensioning device will automatically lock into a selected position. Additional embodiments include digits with dual internal edges and logarithmic spiral contours for enhanced grasping of objects. Still further embodiments include illumination for functional and aesthetic purposes.Type: GrantFiled: May 15, 2009Date of Patent: November 8, 2011Assignee: Invisible Hand Enterprises, LLCInventor: Bradley Delton Veatch
