Embodiment 1

[0046] like Figures 1 to 18 As shown, a minimally invasive lumbosacral unidirectional barbed axial fusion internal fixation system includes an implant rod 1, an internal fixator 2, a thorn blade pushing mechanism 3, an anterior thorn blade mechanism 4, a rear thorn blade mechanism 5, a plug Head push rod 6, front plug 7, rear plug 8 and locking pin 9.

[0047] The implant rod 1 has a tubular shape and is provided with a through inner hole 11. The inner hole 11 is provided with a locking pin groove A112 that extends along the axial direction and runs through the entire length of the inner hole 11. The front end of the inner hole 11 is a screw hole section C111. . The implant rod 1 is also fixed with a positioning block 12 , and the positioning block 12 is provided with a positioning hole 121 and a locking pin groove C122 into which the bent section 91 of the locking pin 9 falls.

[0048] The inner fixer 2 is a stepped cylindrical body, one end of which is provided with a scr...

Abstract

An internal fixing system for minimally invasive lumbosacral vertebrae one-way axial fusion with a spine comprises an implantation rod, an internal fixator, spine sheet pushing mechanisms, a front spine sheet mechanism, a rear spine sheet mechanism, a plug pushing rod, a front plug and a rear plug. After the internal fixator is mounted between a vertebral body of a waist 5 and a sacrum 1 of a patient, the front plug, a front spine sheet, a rear spine sheet and the rear plug are sequentially mounted. A blade of the front spine sheet and a blade of the rear spine sheet are drilled out from an axial kidney-shaped hole A and an axial kidney-shaped hole B in the internal fixator and the two blades are inserted in two vertebrae of the patient respectively. Relative rotation between the two vertebrae can be effectively prevented, the number of wounds needing to be opened in the body surface of the patient during an operation is decreased, and the amount of bleeding during the operation is reduced. Compared with existing lumbosacral vertebrae axial fusion with a lock, the internal fixing operation difficulty and operating difficulty are lowered, and operation time can be shortened.

Description

technical field [0001] The invention relates to an orthopedic surgical instrument, in particular to a minimally invasive lumbosacral vertebra unidirectional barbed axial fusion internal fixation system. Background technique [0002] Lumbar-sacral fusion is a common surgical method for the clinical treatment of lumbosacral degeneration and instability. At present, routine anterior surgery in clinical practice is easy to damage internal organs, blood vessels and nerves, while posterior surgery interferes greatly with the physiological function of the spine and does not conform to the biomechanical structure of the spine. In the past decade or so, with the development of minimally invasive concepts and science and technology, the new minimally invasive anterior lumbar spine surgery represented by laparoscopic anterior puncture, minimally invasive small incision, and percutaneous internal fixation and fusion has made great progress. . [0003] The invention patent with the pub...
