1296 results about "Hand palms" patented technology

The palm comprises the underside of the human hand. Also known as the broad palm or metacarpus, it consists of the area between the five phalanges (finger bones) and the carpus (wrist joint).

Under-actuated artificial limb hand

The invention provides an under-actuated artificial limb hand which comprises a palm, a thumb and four fingers, wherein the fingers are composed of finger main bodies and driving mechanisms in the finger main bodies; the thumb is composed of a thumb main body and a driving mechanism in the thumb main body; a finger-web driving mechanism and a thumb driving mechanism are arranged in the palm; pulleys are taken as the main parts of the finger main bodies; tensioning ropes and releasing ropes are adopted by the driving mechanisms in the fingers and are alternately wound on the pulleys of the fingers; a single motor is adopted by the finger-web driving mechanism for driving two fingers and multiple degrees of freedom; a pulley is taken as the main part of the thumb main body; driving ropes are used as driving mediums by the driving mechanisms in the finger main bodies: a slot wheel component, a gear component and a crank block component are adopted for coordinately driving by the finger-web driving mechanism, so that the control of the single motor on the multiple degrees of freedom of the thumb is realized. According to the under-actuated artificial limb hand, the fingers, the thumb and the driving mechanisms thereof form an under-actuated mechanism for finishing the enveloping self-adaption capture for various articles, the structure is simple, the volume is small, the weight is light and the under-actuated artificial limb hand is attractive and practical.

Under-actuated prosthetic hand capable of reproducing hand grasping function

ActiveCN104382674APrecise bendingPrecise straighteningArtificial handsElastic componentCoupling
The invention discloses an under-actuated prosthetic hand capable of reproducing a hand grasping function; the under-actuated prosthetic hand is provided with an interphalangeal drive mechanism and a thumb drive mechanism in a palm; finger bodies take pulleys as main parts, and transmission mechanisms arranged in fingers are sequentially and alternately wound on all the pulleys of the fingers by steel wire ropes; joints in the fingers are in flexible coupling by elastic components; the interphalangeal drive mechanism adopts two motors to drive four fingers and multiple degrees of freedom of the fingers in a synergetic way; a thumb body takes a pulley as a main part, the transmission mechanisms in the finger bodies take transmission ropes as transmission mediums, the interphalangeal drive mechanism adopts a gear component for transmission matching, and the four degrees of freedom of the thumb can be controlled by two motors. After the under-actuated prosthetic hand is adopted, self-adaptive grasping of various objects can be accurately completed, and the rich grasping operation function of a human hand can be reproduced; the under-actuated prosthetic hand has the characteristics of being compact in structure, smaller in size, lighter in weight, convenient to control, accurate in grasping action, and the like.

Triangular hand massager

InactiveUS6241694B1Easily and firmly held with minimal effortFunctionalSurgeryGenitals massageMassageEngineering
An aesthetic and highly functional massage tool is disclosed which comprises a generally triangular frame adapted to be held in the palm of one hand. It has three leg members, each leg member extending generally from a bottom side corner portion of the frame a height generally exceeding the thickness of a finger. Each leg having a generally rounded bottom portion. The legs and triangular frame are monolithically molded from plastic. The frame has a generally triangular opening so that one may extend their fingers therethrough and around a side portion of the frame. This triangular design enables one to securely and comfortably hold the massage tool in multiple positions while during use. This is important because use in any one position tires particular muscles of the massageur. It also facilitates massaging different body portions in differing manners. The triangular void facilitates wrapping one's fingers around the massage tool. It enables one to slide the tool along while pushing downwardly on it. One's hand effortlessly falls within the triangular void and over the exterior of the triangular frame sufficiently to prevent the tool from slipping out from beneath one's hand. The triangular void also allows one to massage holding the tool in an upright position. In the most preferred embodiment the generally triangular frame has the shape of a heart and the plastic is marbled in more than one color.
