摘要： Various embodiments of the present invention generally relate to prosthetic partial finger designs that can mimic the last two joints of the finger. Some embodiments include a proximal phalange, a distal phalange coupled to the proximal phalange, and a knuckle track (e.g., formed in an arc). The knuckle track can be moveably coupled to the proximal phalange an may include multiple teeth formed on which the proximal phalange slides along. A ratcheting mechanism can contact the multiple teeth to allow sliding in only a first direction while the ratcheting mechanism is engaged. Some embodiments include a release mechanism (e.g., a button) configured to disengage the ratcheting mechanism from the multiple teeth to allow the distal phalange to slide in a second direction. In some embodiments, the device may include a spring-back capability that automatically extends the finger after reaching full finger flexion, enabling one-handed use.

摘要： Systems and methods for postural control of a multi-function prosthesis are provided. Various embodiments provide for a postural controller that use EMG signals to drive a point in a posture space and outputs continuously varying joint angles for a powered prosthetic hand. The postural controller can include an EMG signal processing unit to receive signals from electrodes for processing (e.g., band pass filtering, rectification, root mean square averaging, dynamic tuning, etc.). The processed EMG signals can then be combined or converted to produce a point in the postural control domain. The PC domain map defines the posture that corresponds to each PC cursor coordinate. This map can have limitless possible postures and limitless possible positions of the postures. The Joint Angle Transform converts the PC cursor coordinate into the joint angle array which is sent to the prosthetic hand thereby creating more natural movements.

摘要： Various embodiments of the present technology generally relate to robotics and prosthetics. More specifically, some embodiments of the present technology relate to multi-modal fingertip sensors with proximity, contact, and for localization capabilities. Various embodiments of the present technology provide for a novel multi-modal tactile sensor which comprises an infrared proximity sensor and a barometric pressure sensor embedded in an elastomer layer. Signals from both of these sensors can be fused to measure proximity (0-10 mm), contact (0N), force (0-50N) and localize impact at five spatial locations and three angles of incidence. Gaussian processes in a regression setting can be used to obtain calibrated force measurements with an R-squared value of 0.99. Supervised machine learning approaches can be used to localize the position and direction of probing with classification accuracies of 96% and 89% respectively.

摘要： A slotted cannula for surgical procedures is disclosed. The slotted cannula has an elongated semi-circular body comprising a cavity extending along a longitudinal axis of the semi-circular body, the cavity having an open distal end and an open proximate end and an integrally formed outward bend extending curvilinear from the cavity on the proximate end and at least one fold line across the width of the cannula, perpendicular to the longitudinal axis. The cannula can be bent or broken along the at least one fold line to adjust the operable length of the cannula during a surgical procedure.

摘要： Embodiments disclosed herein concern a distraction system for use with a surgical table having a table portion and a base portion. The distraction system includes a pair of arms rotatably connectable to the base portion at a proximal end portion of each arm. A pair of telescopically adjustable support posts extend upwardly from corresponding arms. Each arm rotates about a vertically oriented axis to provide for hip adduction and abduction of a patient's leg. Each support post extends from a linear bearing attacked to the corresponding one of the pair of arms for movement along the arm to facilitate applying traction to a patient's leg. The system can also include a table extension attachable to the table portion and a friction pad mounted on the table extension.
