    摘要： An artificial forearm and hand having a fully-articulated wrist motion. The invention provides an integrated digitally-controlled remote manipulator device capable of reproducing all of the major motions of the human forearm, wrist and hand in a cmpact in-line package. This motion is accomplished without the requirement for feedback thereby making the invention ideally suited to digital computer control. The packaging of the device permits it to be sealed, meaning that it can be used as a remote manipulator that can reproduce human arm and hand motions. The packaging also produces a lightweight, cosmetically pleasing prosthetic device for use by humans.

    摘要： A system for controlling the operation of an electrically powered prosthetic appliance which replaces an amputee's missing limb. The method employed consists of conducting electromyographic (EMG) signals from the stump of the missing limb and processing the signals so as to reduce them to a near minimum number of linear time series model parameters effective to differentiate between each of the several functions performed by the missing limb from each other function thereof. A filter array carried by the amputee subsequently employs the identified parameters such that each individual filter of the array is tuned according to a set of parameters related to one of the limb functions considered. The myoelectric (EMG or ME) signal as obtained at a surface electrode worn by the amputee is fed to each filter of the above array of filters, and the outputs of these various filters are used for a decision by the system as to which limb function should be actuated. In another realization, identification of partial correlation coefficients of the ME signal is performed. These coefficients are stored in memory per each limb function, and during normal operation the partial correlation parameters for the current ME signal are compared with those in memory to determine which limb function is to be actuated.

    摘要： A prosthetic wrist fitting for attachment to a fore-arm termination comprises a socket with an internally toothed ring surrounding its mouth and a complementary plug having an externally toothed ring so that the plug may be engaged with the socket in angularly adjusted relation. The plug is maintained in the socket against ejection by a spring by engagement of a keep ring slidable across the socket bore and engaging a groove in the plug. The internally toothed ring may be rotatable relatively to the body socket axis and provided with a number of over-ridable detents so that the plug may be turned through angular steps without removal from the socket. A manually operated catch retains the plug in any selected one of these adjusted steps.

    摘要： An apparatus for connecting a prosthesis to a bone of a stump of an amputated limb such as the arm or leg of a person. The apparatus includes a tubular female socket adapted to be inserted within an intermedullary cavity of the bone. The tubular socket has an open lower end with a sleeve of bio-compatible material permitting access through the skin of the amputee's stump. The prosthesis has a contoured support for receiving the stump of the amputee. A quick disconnecting lock pin is carried adjacent the center of the contoured support. The lock pin is adapted to be received within the female socket for securing the prosthesis to the tubular female socket carried within the bone. The mounting for the lock pin is adjustable so that the degree of support provided through the bone as compared to the degree of support provided through the flesh of the stump engaging the wall of the prosthesis can be varied.

    摘要： A prosthetic arm has an upper arm member having a stump receiving socket, a forearm member and an elbow unit secured to the upper arm member and pivotally connected to the forearm member. A drive, housed within the elbow unit, includes a reversible direct current permanent magnet torque motor and a transmission including a planetary gear reduction unit, a reverse locking clutch, and a plano-centric unit and the transmission is connected to the forearm member with its output shaft part of the pivotal connection therewith. The forearm member houses a battery pack and the circuitry by which the motor is operated in either direction in response to electromyographic signals that may be picked up from the biceps and triceps by electrodes when attached to the stump and processed to drive the motor in a direction and at a rate dependent on the dominant EMG signals. The locking clutch is operable to hold the arm flexed against a predetermined load and the elbow unit also houses a tachometer to provide a feedback to modify the power supplied to the motor to enhance the controlability of the amputee of flexing velocities.

    摘要： This disclosure is directed to a mechanical hand constructed to simulate the articulated movements of a human hand. The mechanical hand comprises a base member simulating the palm portion of a human hand with a plurality of finger digits and a thumb digit articulated to the base portion. Each finger and thumb digit includes pivotally connected segments or joints to simulate or duplicate the finger and thumb movements of a human hand. Tendons are operatively connected to each of the respective digits to effect the flexing thereof, and an actuator is operatively associated with each of the respective tendons to effect either independent and/or simultaneous actuation of the respective digits for movement between operative and inoperative positions.
