detailed description

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment of the present invention: the structural schematic diagram of the device for minimally invasive surgery of the cervical spine is shown in Figures 1-2, including a sleeve 1, and the sleeve 1 includes an outer core 11, a scale 12, a pressing point 13, a sharp needle 14. The spring 15 and the handle 16. The outer surface of the outer core 11 is provided with a scale 12. The outer end of the outer core 11 is integrally provided with a handle 16. The outer core 11 is also movable with a pressing point 13. The pressing point 13 A sharp needle 14 is integrated on one side of the body, a spring 15 is installed inside the pressing point 13, and an auger bone drill 2 is installed inside the outer core 11, and the auger bone drill 2 can be drilled into the inside of the vertebral body of the spine, The bone drill 2 includes an inner core 21, a hand-held rotating head 22 and sawtooth 23. An inner core 21 is installed inside the outer core 11. The inner core 21 is a member of a hollow structure. One end of the inner core 21 is integrally provided with a hand Hold the rotating head 22, the other end of the inner core 21 is provided with a sawtooth 23, and the inside of the inner core 21 is provided with a threaded bone extractor 3, which includes a bone extractor main body 31, a fixed cap 32, an operating device 33, a movable Head 34 and bone-taking blade 35, one end of bone-taking device main body 31 is equipped with fixed cap 32, and operating device 33 is installed on the fixed cap 32, and the other end of bone-taking device main body 31 is equipped with movable head 34, and movable head 34 is movable The bone extraction blade 35 is installed, and the inner core 21 is provided with a positioning pin 4.
