A low rigidity region being more stretchable and bendable than a high rigidity region, includes a main portion, and a medial first flexible portion and a lateral first flexible portion extending from the main portion in the medial and lateral directions. The main portion covers a portion of the area from the shaft of the first proximal phalanx to the shaft of the second proximal phalanx, the medial first flexible portion covers a portion of the area from the shaft of the first proximal phalanx to the head of the first metatarsal bone, and the lateral first flexible portion extends to the lateral side of the foot from the main portion. When pushing off the foot onto the medial / lateral side in a diagonally forward direction, the upper bends along the diagonal bend lines. Therefore, the diagonal portions and the main portion serve as the bend lines.

The invention discloses the foot of a humanoid robot and a control method of the foot of the humanoid robot. The foot of the humanoid robot is characterized in that an upper disc body is arranged to serve as an ankle bone, the rear end face of the ankle bone is a plane, the front end face of the ankle bone is in a V shape when the front end face of the ankle bone is overlooked, an outer front end face body and an inner front end face body are symmetrically arranged on the V-shaped front end face, the ankle bone is supported in a three-force-point mode through three rod pieces on the rear end face and the front end face of the ankle bone, the three rod pieces refer to a heel bone, an inner metatarsal bone and an outer metatarsal bone, a rear planta pedis stress triangle is formed with the lower end of the ankle bone as a rear vertex and a point head facing backwards, and the upper end face of the ankle bone is connected with the lower limbs of the robot through ankle joints. According to the foot of the humanoid robot and the control method of the foot of the humanoid robot, linear driving devices are arranged on the lower limbs of the robot, all components are driven through flexible ropes according to set actions, and thus rotation of the foot joints of the robot is driven and controlled.

The invention provides a fastener implant for osteosynthesis of fragments of the first metatarsal bone in its proximal portion situated towards the tarsal bone, the implant comprising at least a fastener element for fastening via a fastener face on or against the outside surface of the first metatarsal bone in order to hold the bone fragments together, wherein said fastener face includes at least one anatomical surface portion of shape that is substantially complementary to the shape of the plantar surface of the proximal portion of the first metatarsal bone.

A shoe insole, which supports three points on a sole to stabilize a center of gravity, is provided by considering a skeletal structure of a foot and a sequential movement from foot joints to a body. The three points, which are a first metatarsal sesamoid bone, tuberosity of fifth metatarsal bone, and a calcaneal tuberosity, are supported from a sole side, and the three point balance can stabilize a center of gravity, and thereby a stimulus that adjusts body movements derived from a sole to help a body to be back to a right position can be given.

A fully automatic airbag-type smart shoe, including an airbag-type upper. The structural formula of the airbag-type upper is: at least two airbag blocks, and the airbag blocks are connected. When the airbag shrinks, the pressure on the foot is the first The dorsal and medial sides of the first metatarsal, the dorsal and lateral sides of the second, third, and fourth metatarsals, the dorsal and lateral sides of the fifth metatarsal, the medial and lateral cuneiforms; , the inflating device inflates the airbag to realize the fit between the airbag and the instep. When taking off the shoes, the exhaust device starts to discharge the gas in the airbag; The internal preset value of the MCU processor determines the pressure or decompression of the airbag to realize the automatic operation of the airbag. It is also possible to link the mobile device through the Bluetooth chip and manually set the value in the processor to meet the needs of different individuals.

The present invention relates to a midsole for dispersing the pressure of the mesopodium and the metatarsal bones, and a shoe having the same, the midsole having, installed in a metatarsal bone portion and mesopodium portion of the central upper part thereof, a midfoot support for receiving an inner sole, which protrudes upwardly so as to support the mesopodium, and having a bridge groove formed in a metatarsal bone portion of the lower part thereof, wherein the bridge groove consists of three components, and has been improved so as to be capable of supporting joints between the metatarsal bone body and basal tarsus metatarsal bones.

An orthopedic instrument assembly for placing an implant into a medial cuneiform of a foot, the assembly includes a targeting guide having a body with an elongated linear base. A threaded rack is disposed along the elongated linear base. A compression-distraction frame pre-compresses the joint prior to placement of a joint fixation element. The compression-distraction frame is translatably connected to the rack of the guide body base. The compression-distraction frame is releasably, statically connectable to a first metatarsal bone and a post. The post has a generally cylindrical shape and a longitudinal axis, and has a plurality of threaded cylindrical bores disposed therethrough at predefined angles relative to the longitudinal axis. The post is releasably, statically connectable to the targeting guide.

The invention discloses a device for treating dysarthrosis. The device at least includes a first base, a second base, a push portion, and a support portion. The heel of the foot of a human is attachedon one side surface of the first base. The second base and the first base form an included angle. The second base has one end disposed on the side surface of the first base, and the sole of the footof the human is attached on one side surface of the second base. The push portion is disposed on the second base has an abutting surface corresponding to the outer side of the first toe of the human foot, is configured to abut against the outer side of the joints of the phalanx and the first metatarsal bone, and is moved between a first position and a second position. The support portion is disposed on the second base, has one end located between the first toe and the second toe of the human foot, and is abutted against one side of the first toe. The device can effectively treat dysarthrosis in real time.

The invention discloses a human body identity recognition system which comprises a pressure measurement device, a signal conditioning circuit, an analog / digital (A / D) converter, a microprocessor, a wireless transmission module, a wireless receiving module and an upper computer which are electrically connected in sequence. The system is characterized in that the pressure measurement device is a sock-type foot pressure measurement device which mainly comprises a sensor array mainly composed of 19 miniature pressure sensors; the miniature pressure sensor array is placed at the bottom of the sock-type foot pressure measurement device, and is distributed according to corresponding positions as follows: the first toe to the fifth toe are respectively provided with one miniature pressure sensor;the far ends of first, second, third, fourth and fifth metatarsal bones are respectively provided with miniature pressure sensor; the near ends of first, second, third, fourth and fifth metatarsal bones are respectively provided with one miniature pressure sensor; cuneiform bone, the middle part of navicular bone and the tail end of the navicular bone are respectively provided with one miniature pressure sensor; and four miniature pressure sensors are distributed at calcaneus.
