Surgical instrument for endoscopic surgery that permits the simulation of the articulation movements of a surgeon finger, comprising a rigid tube (3) whose distal end has a first phalanx (4) articulated, being in turn articulated to a second phalanx (5), which is linked to the rigid tube (3) by means of cables housed in cross ducts (12), situated in the interior of the first phalanx (4), linking the movement of the second phalanx (5) to that of the first phalanx (4), whose articulation takes place due to the actuation of the transmission rod (11), the rigid tube (3) being attachable to a handle (1) that incorporates a controller (2) for the actuating of the instrument articulation movement by the surgeon, which operates a fork (14), which in turns actuates the transmission rod (11).

Surgical methods and fixation devices for bone fixation and stabilization on a patient include exposing at least a portion of a first phalanx and a second phalanx at a joint of a patient; creating a passage in an intramedullary canal of the first phalanx; inserting a first head portion of a fixation device along the passage in the intramedullary canal in a translating manner past the cancellous bone in the phalanx until the head portion engages the subchondral bone at a base of the first phalanx, the fixation device having an opposing second head portion extending out of the passage from the first phalanx; and introducing the second phalanx onto the second head portion so that the second head portion anchors in the second phalanx.

The invention discloses a basketball shooting training device and a wearing method of the basketball shooting training device. A magnetic stick is installed on the back face of a first phalanx of a middle finger of a shooting glove, reed pipes are installed at the periphery of the magnetic stick, normally-opened type reed pipes or normally-closed type reed pipes or simultaneously-installed the normally-opened type reed pipes and the normally-closed type reed pipes are arranged on the back face of a first phalanx of an index finger and the back face of a first phalanx of a ring finger, the back face of a metacarpal bone of the middle finger and the back face of a second phalanx of the middle finger, and when the reed pipes are all communicated and the communication continuous time reaches the set time t1 second, a first single chip microcomputer continuously outputs a low level for the time t2 second, and an output device obtains power to conduct working so as to remind a trainer that the hand shape is correct. When the communication continuous time of the reed pipes does not reach the set time t1 second or any one or more than one reed pipe is not communicated, the output device does not obtain the power so as to stop working. The basketball shooting training device not only can independently train the shooting hand shape, but also can be combined with a palm horizontal meter, a front arm vertical meter and an upper arm horizontal meter to complete three 90 degrees and stimulate lower limb strength training, training is more complete, and the basketball shooting training device is more convenient to wear.

The present invention relates to a protective device (1) for protecting a proximal interphalangeal joint and a distal interphalangeal joint of a human finger. The device comprises a flexible sheath (3) for wearing around the human finger and at least four motion constraining elements (4) integrated in or secured to the flexible sheath (3). The motion constraining element (4) is adapted for constraining a lateral and / or rotational deviation motion of a first phalanx with respect to a second phalanx. The motion constraining element (4) covers a lateral side (L) of the flexible sheath (3) at a location corresponding to the joint (2) and is adapted for resisting elongation of the motion constraining element (4) in a longitudinal direction (5) of the flexible sheath (3). The motion constrainingelement (4) is bendable in a direction to allow flexion of the joint (2). The motion constraining elements for the distal interphalangeal joint and for the proximal interphalangeal joint are distinctand separate elements having different points of engagement on the flexible sheath.

The invention discloses a buffering energy-saving and active anti-subsidence bionic mechanical foot. The foot is composed of a tarsometatarsus, metatarsophalangeal joints, a second phalanx, a third phalanx, a steering engine and a toe pad; each metatarsophalangeal joint is composed of a base, a support, a connection rod, a spring, a horizontal slider, a first phalanx, a vertical slider, a hinge pin and the like. Ostrich feet are used as a bionic prototype. On one hand, considering the motion morphology of sand touching and sand crossing of the ostrich feet when an ostrich runs on the sand land at high speed, the metatarsophalangeal joints which are permanently kept off the sand land are designed, and energy-storage, buffering and energy-saving effects are achieved; on the other hand, considering the aspect of material assembly, the phalanx adopts rigid materials, the toe pad adopts rubber materials, and rigid-flexible coupling plays a role in protecting a skeleton. Besides, considering the ostrich feet sand-off posture and active anti-subsidence characteristics, the steering engine drives the phalanxes to be off the sand land in sequence, and the active anti-subsidence effect is achieved. The bionic mechanical foot is simple in structure and multifunctional, and helps to improve the walking ability of a robot in the soft ground like sand land.

The invention discloses a biomechanics-based children shoe sole. The shoe sole is shaped like a fan with the wide front portion and the narrow rear portion, and comprises a landing layer, a pressure layer, a protective layer and a foot arch supporting layer. The hardness of the foot arch portion and the hardness of the heel portion of the landing layer are greater than that of the half sole portion. The hardness of the portion from the third phalanx to the fifth phalanx, the portion of the first phalanx and the portion of the inner side of the heel, the hardness of the portion between the first phalanx and the second phalanx, the portion between the fourth phalanx to the fifth phalanx and the portion of the outer side of the heel, the hardness of the portion between the second phalanx and the third phalanx and the hardness of other portions of the pressure layer are reduced gradually. The protective layer is made of slowly recovering materials. The shape of the foot arch supporting layer is the same with the shape of the foot arch of a child. The thickness of the foot arch supporting layer is decreased gradually from the inner side to the outer side in the transverse arch direction of the foot arch, and is decreased gradually from the middle to the two sides in the inner side longitudinal arch direction and the outer side longitudinal arch direction of the foot arch. The biomechanics-based children shoe sole has the advantages of meeting the children biomechanics characteristic, being high in comfort level and impact resistance, and the like.
