Embodiment Construction

[0024] Figure 1 and Figure 5 Shown: The whole complex external fixator is connected with two rings and four fully threaded rods. The right ring 5 is a tension ring, and its structure has an outer ring 5-1, a ring gear 5-2, a worm 5-3, and four small gears 5-4, wherein a pair of spicule adjustment frames 6 are housed on the outer ring, and the spicules That is, it is installed on the bone needle adjustment frame. The principle is: the worm meshes with the ring gear, the ring gear meshes with the four pinions, the internal threads of the four pinions form the thread width with the four threaded rods, and when the torque is input to the worm, the right ring moves along the four connecting rods Move, and drive the bone needle to move along the X axis through the bone needle adjustment frame. So as to achieve the purpose of stretching or compressing.

[0025] As shown in Figure 2, the left ring is a rotating ring: its structure has an outer ring 2-1, a ring gear 2-2, and a worm ...

Abstract

The computer controlled reduction external fixation system comprises: computer combined equipment is respectively connected with X-ray machine, sensor and two gearboxes, said gearboxes are connected with correspondent soft shaft and manual push-button function display lamp, and the reduction external fixator is respectively connected with sensor and two soft shafts. Said system can utilzie comptuer operation to implement 3-D 6-freedom accurate reduction of fracture in remote control mode. Its reduction process is high in automation, can implement optico-mechanico-electric integration, and can raise reduction accuracy and speed and shorten union period. It is applicable to open fracture, closed fracture and comminuted fracture.

Description

Technical field: [0001] The present invention relates to a surgical bone-synthesizing instrument, in particular to a surgical external bone-synthesized instrument for bone restoration. Background technique: [0002] Traditionally, in the treatment of human long bone fractures, the method of manual bone restoration has been used. The fixation methods include internal fixation with surgical plates and external fixation without surgery, such as plaster fixation, small clip pole fixation, and new materials. coating method. The above methods are difficult to ensure the accuracy of fracture reduction and the stability of fixation, and are prone to infection and nonunion symptoms, and the fracture healing rate is low. [0003] At present, there is a strong call for external fixation of fractures in the world, and a variety of external fixators have come out, such as: HJIn3APOB, KRONER and FISHER external fixators are all manual instruments, and they only have the function of fixat...
