Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] figure 1As shown in -2, the combined ankle three-dimensional traction fixation frame mainly includes a horseshoe-shaped ring 1, four L-shaped connecting rods 9, 10, 11, 12, an L-shaped connecting seat 13, and four carbon fiber connecting rods 17, 18, 19, 20. Six locking pin screws 21, 22, 23, 24, 25, 26 and two locking pin screws 27, 28. The horseshoe-shaped ring 1 is provided with a plurality of through holes along the arc direction, and all the through holes are any one or any combination of round holes and waist-shaped holes. The two through holes 2 and 3 are respectively locked and connected to one end of the first and second L-shaped connecting rods 9 and 10 through nuts, and the other end of the first L-shaped connecting rod 9 passes through the upper and lower connecting rod clamps 15 and 16 and is clamped by nuts One end of the firs...

Abstract

The invention relates to a combination type ankle joint three-dimensional traction fixing frame. The fixing frame mainly comprises a horseshoe-shaped ring and four carbon fiber connecting rods. Three Kirschner pins are locked through pin locking screws, pass through heel bones, shin bones and metatarsal bones three-dimensionally and are fixed on the horseshoe-shaped ring and the four carbon fiberconnecting rods; and one or more ejector pins are locked through the pin locking screws to fix an inner ankle, an outer ankle and a rear ankle of an ankle bone. The fixing frame has a compact and stable structure, is convenient to use and detach and has low using cost, ankle joints and fracture blocks are firmly fixed, periosteum is not required to be stripped by a surgery, and the healing of damaged ankle joints is facilitated.

Description

technical field [0001] The invention relates to an ankle joint traction fixation frame, in particular to a combined ankle joint traction fixation frame for three-dimensional needle fixation. Background technique [0002] At present, traumatic ankle fractures seriously threaten human health and living standards. External fixator refers to a treatment device that percutaneously penetrates the fixation needle at the distal and proximal ends of the fracture, and then connects the needle ends exposed outside the skin with connecting rods and locking needle screws to fix the fracture site. Its advantages It can not only provide stable fixation for the fracture end, but also not destroy the local blood circulation, and create favorable conditions for fracture healing from the aspects of mechanics and biology. There are two kinds of external fixators used in ankle joint fractures at home and abroad: single arm frame and ring frame, both of which have fixation as the main functi...
