Minimally invasive poking orthopedic internal fixator

Abstract

The invention discloses a minimally invasive poking orthopedic internal fixator which comprises fixing bars 1, transverse connecting rods 2, connecting buckles 3, locking hinge components 4, poking hinge components 5, vertebral pedicle locking screws 6 and vertebral pedicle poking screws 7. Two ends of each transverse connecting rod 2 are mounted on the fixing bars 1 via the corresponding connecting buckles 3, the locking hinge components 4 are mounted on the fixing bars 1, the poking hinge components 5 are mounted on the fixing bars 1, the vertebral pedicle poking screws 7 are mounted on the poking hinge components 5, and screws 8 are respectively arranged on the connecting buckles 3, the locking hinge components 4 and the poking hinge components 5. By the aid of the minimally invasive poking orthopedic internal fixator in the design, shortcomings of long wounds, severe hemorrhage, easiness in infection, influence on in-vitro appearance of patients and the like of the current traditional open surgical treatment method can be overcome. Compared with the prior art, the minimally invasive poking orthopedic internal fixator has the advantages of wide application range, simplicity and convenience in operation, structural stability and reliability in usage procedures, good anti-rotation effect and the like.

Description

technical field [0001] The invention relates to an orthopedic surgical instrument, in particular to a minimally invasive prying orthopedic internal fixator for correcting spinal defects. Background technique [0002] At present, for patients with idiopathic scoliosis at home and abroad, traditional open surgery is often used for orthopedic and internal fixation. This treatment method has a long wound, a lot of bleeding, and is prone to infection, which especially affects the external beauty of the patient and is difficult to be accepted by the patient. With the development of high-precision technology of medical equipment and electronic digital imaging technology, the minimally invasive orthopedic surgery technology of the spine has also been developed rapidly, and the minimally invasive surgery orthopedic internal fixation treatment of the spine has been realized. This minimally invasive surgical orthopedic internal fixation treatment method is due to Small trauma, less bl...

AI Technical Summary

Problems solved by technology

This treatment method has a long wound, a lot of bleeding, and is prone to infection, especially because it affects the external beauty of the patient and is difficult to be accepted by the patient.

With the development of high-precision technology of medical equipment and electronic digital imaging technology, the minimally invasive orthopedic surgery technology of the spine has also been developed rapidly, and the minimally invasive surgery orthopedic internal fixation treatment of the spine has been realized. This minimally invasive surgical orthopedic internal fixation treatment method is due to Small trauma, less bleeding, less infection, does not affect the patient's beauty and is widely accepted by patients. To a certain extent, it overcomes the shortcomings of traditional open surgery, such as the minimally invasive spinal surgery invented by the Second Affiliated Hospital of the Third Military Medical University of the Chinese People's Liberation Army A pedicle screw and a spinal percutaneous internal fixation system (CN201210395392.7), which are only suitable for minimally invasive orthopedic internal fixation of thoracolumbar fractures and minimally invasive internal fixation of some thoracolumbar bone diseases, The scope of use is narrow, minimally invasive orthopedic internal fixation cannot be performed for idiopathic scoliosis, and the stability is poor (it uses two-dimensional fixation)
