An orthopedic appliance includes a slab configured to be placed underneath a big toe, forward of and not extending under a head of a first metatarsal, and wherein the slab has a predetermined height and is configured to deflect a proximal phalanx upwardly relative to the first metatarsal. A method for improving stability of a foot during ambulation includes placing an orthopedic appliance, having a predetermined height, under a big toe such that the orthopedic appliance is located forward of and does not extend under a head of a first metatarsal of the big toe; and deflecting a proximal phalanx upwardly relative to the first metatarsal.

A mechanical finger comprises at least three phalanges, with a base phalanx pivotally connected at a proximal end to a base. At least one intermediate phalanx is pivotally connected at a proximal end to a distal end of the base phalanx. An end phalanx is pivotally connected at a proximal end to a distal end of a distal-most one of the at least one intermediate phalanx. The phalanges pivot about parallel pivot axes. A transmission linkage is between the base and the end phalanx. The transmission linkage has links and joints unconnected to any of the phalanges other than the end phalanx, the transmission linkage being configured so as not to constrain the degrees of freedom of the mechanical finger.

A glove formed of a flexible fabric, such as a natural or synthetic knit fabric, provides anterior and posterior portions having the outline of the phalanges and metacarpals of a human hand. A fourchette joins the anterior and posterior portions to one another. The fourchette has an arcuate shape prior to securement to the glove and thereby tends to curve the phalangeal portions of the glove. The fourchette extends to the lower edge of the cuff. Joints between the fourchette and the anterior and posterior portions maintain an opening formed by the cuff in an open position.

The invention belongs to the technical field of robots, and relates to a finger structure and a robot. In the finger structure, a proximal phalanx shell, a middle phalanx shell, a distal phalanx shelland a connecting rod form a four-rod mechanism, the proximal phalanx shell serves as a fixing frame, a driving assembly drives the middle phalanx shell to swing, the distal phalanx shell is in linkage with the connecting rod, the distal phalanx shell swings in the swinging direction of the middle phalanx shell, and the finger structure is integrally bent and straightened. The connecting rod is arranged to be a first bent section, and a notch of the first bent section faces the back face of the middle phalanx shell. When the finger structure is straightened, namely the distal phalanx shell isflush with the middle phalanx shell, the inner wall of the first near end at a distal phalanx opening extends into the bottom of the notch of the first bent section, so that the inner wall of the first near end can be closer to the center of the distal phalanx opening. The far finger opening of the finger structure can be manufactured to be small, and the integrity of the appearance of the distalphalanx shell is improved. Due to the existence of the first bent section of the connecting rod, when the distal phalanx shell is impacted, the connecting rod shows certain elasticity and absorbs theimpact.

A mechanical finger which visually and functionally resembles a human finger. The finger consists of three phalanges pivoted in their clevises. The first phalange is driven by a rod located in an arm and being connected to an actuator. The second and third phalanges are driven by tendons. The tension of the second phalange tendon is initiated by the movement of the first phalange and the tension of the third phalange tendon is initiated by the movement of the second phalange.

A manual control device including a handle configured to be grasped by a hand with a thumb, and a trigger configured to be subjected to a pressure from the distal phalanx of the thumb. The trigger is placed relative to the handle so as to be able to be subjected to a pressure from the distal phalanx while the proximal phalanx from the thumb is resting along the handle.

A robotic gripping device allows for pinch and power grasps using interconnected phalanges with configurable connections. A distal phalange is rotatably connected to a proximal phalange. A contact phalange is rotatably connected to the proximal phalange. The contact phalange is rotatably connected to the distal phalange via a contact-distal pivot or rotation connection. In response to sufficient contact between the contact phalange and an object, the contact phalange is configured to rotate in a first direction toward the proximal phalange. The rotation of the contact phalange causes rotation of the distal phalange in a second direction toward the object. The contact-distal connection may be a configurable gear connection for adjusting the movement ratio of the contact and distal phalanges.

Prosthesis for at least one cut-off finger resulting in a stump at the height of the proximal, middle and / or distal phalange, or in a finger with missing stump. The prosthesis from a modular hinged mechanism allowing for a self-return flexion movement and the activation of said mechanism from at least one force applied to any point of a plane on said mechanism. A prosthesis for a hand with missing stumps is also provided from the wrist movement providing a range of operation greater than the art, wherein said flexion is activated from an extension movement of the wrist.

The invention discloses a wearable finger rehabilitation training exoskeleton. The wearable finger rehabilitation training exoskeleton comprises a supporting frame, a driver, a first connecting rod, asecond connecting rod, a third connecting rod, a first phalanx supporting piece and a second phalanx supporting piece. The supporting frame, the driver and the first connecting rod form a first triangular structure; the first connecting rod, the second connecting rod and a near knuckle form a second triangular structure; and the second connecting rod, the third connecting rod and a middle knuckleform a third triangular structure. The wearable finger rehabilitation training exoskeleton can drive fingers to perform periodic bending training, is good in structure, concise in appearance, relatively low in cost and relatively small in size, is suitable for being popularized in families or communities, and can meet the requirements of different users.

A bionic manipulator has a palm, a thumb 1, an index finger, a middle finger, a ring finger 4 and a little finger, the index finger, the middle finger, the ring finger 4 and the little finger have respective proximal knuckles, middle knuckles and far knuckles, and the proximal knuckles are hinged to the palm; Each joint has its own pair of wire shafts and a spring located between the insertion points; each finger has its own drive motor and force output line, and each force output line includes at least two segments that can be intertwined with each other. The output line passes through the wire shaft on the finger in turn, the far end is fixed with the wire shaft on the far knuckle, and the other end of the line segment is fixed with the output end of the motor. The twisted force output line is used to drive the finger to bend, and the torque of the motor is converted to the length change of the force output line. The force output line bears a small pulling force, is not easy to break, and has a large output force.
