    摘要: The present invention relates to a wing-shaped angle steel plate and a bone shaft fixation system. The wing-shaped angle steel plate comprises a wing fitting portion and a body fixation portion which are fixedly connected to each other. The wing fitting portion is used for supporting a fracture end and has a structure matched with an inner side surface of a bone shaft. The body fixation portion is used for fixing the wing fitting portion and has a structure matched with a front side of the bone shaft. The body fixation portion is provided with at least two first locking holes for passing through first locking screws at an intersection site with the wing fitting portion and is further provided with at least two second locking holes for passing through second locking screws in the structure matched with the front side of the bone shaft. In the wing-shaped angle steel plate, the wing fitting portion and the body fixation portion of the present invention are connected to each other and cooperate to fix and support the bone shaft fracture end site, and effectively ensure and help stable reduction and healing of the fracture sites.

    摘要: A long-bone fracture-reduction robot is provided, and includes a machine base; a support slidably connected onto the machine base and able to move up and down; a plurality of electro-hydraulic drivers; and a six-degrees-of-freedom parallel robot arranged on the support, with the motion of the robot in six degrees of freedom hydraulically controllable using the plurality of electro-hydraulic drivers. The long-bone fracture-reduction robot includes two long-bone-fixing frames, one frame being coupled to the support and other being coupled to the six-degree-of-freedom parallel robot. The two long-bone-fixing frames are arranged to be side by side. Each of the two long-bone-fixing frames is fixedly connected to a corresponding mounting-and fixing plate.

    摘要: The present invention discloses a proximal humerus fixing device. The fixing device comprises: a fixer, a main nail, anti-rotation nails and locking nails; the fixer is disposed in a medullary cavity of the proximal humerus and is matched with the medullary cavity of the proximal humerus; the upper end of the fixer comprises a first contact portion and a second contact portion; the first contact portion is in contact with a head of the humerus and is of a plane structure; the second contact portion is in contact with the greater tuberosity of the humerus and is in a protrusion shape; the far end of the lower end of the fixer is in a bullet shape, and the lower end of the fixer is not in contact with the medullary cavity; the main nail is used for fixing the head of the humerus and the first contact portion; the head of each anti-rotation nail enters the head of the humerus, and the tail portion of each anti-rotation nail is fixedly connected with the fixer; the locking nails are disposed on the lower end of the fixer and are used for enabling the fixer and the humeral shaft to be fixedly connected with each other. The proximal humerus fixing device of the present invention is applied to the proximal humerus serious comminuted fracture complicated by or not complicated by shoulder dearticulation, the fixing treatment effect is good, and the surgical risk is small.
