The invention relates to the technical field of vertebral body fusion devices, in particular to a vertebral body fusion device capable of well supporting and fixing a vertebral body. The vertebral body fusion device comprises a first outer shell, a second outer shell, a first sleeve, a second sleeve, a push rod, a first distraction component, a second distraction component and a sliding block component. One end of the first outer shell stretches into the second outer shell. The first sleeve and the push rod are arranged in the first outer shell. One end of the push rod stretches into the first sleeve, the first sleeve is sleeved with one end of the second sleeve, and the other end of the second sleeve is located in the second outer shell. The first distraction component and the second distraction component are respectively connected with the sliding block component in a movable mode, and the first sleeve is movably connected with the second sleeve. The vertebral body fusion device is convenient to operate and capable of playing a good supporting role in a spine, facilitates the operation of surgery, and has good stability.
Description
technical field [0001] The invention relates to the technical field of vertebral body fusion devices, in particular to a vertebral body fusion device capable of better supporting and fixing vertebral bodies. Background technique [0002] The vertebral body fusion device is placed between the spinal segments to support the spine. Although the existing vertebral body fusion device can also support the spine, its stability is poor. Also can move thereupon simultaneously, if the supporting effect of vertebral fusion device is poor, just can't reach the purpose of expected treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vertebral body fusion device by overcoming the deficiencies in the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is: a vertebral body fusion device, including a first shell, a second shell, a first sleeve, a second sleeve, a pus...
