Abstract

The invention discloses a lumbar lateral-anterior approach self-locking interbody fusion fixing device which comprises a fixing piece and an operation channel matched with the fixing piece. The fixingpiece comprises an interbody fusion device and self-locking nails; a plurality of positioning holes are formed in the interbody fusion device; and the interbody fusion device is connected with the self-locking nails through the positioning holes. The operation channel comprises a plurality of fasteners, protection corners, protection edges, an illumination device and a camera device; the fasteners are connected with the protection corners; the protection edges are mounted between the adjacent protection corners; a channel main body is defined by the multiple adjacent protection edges and protection corners jointly; the illumination device is connected with the protection corners; and the camera device is connected with the protection edges. The lumbar lateral-anterior approach self-locking interbody fusion fixing device has the beneficial effects that 1, the operation view is enlarged, and the operation time is shortened; 2, mounting, operation and using are facilitated; 3, using is safe and reliable, and direct decompression is achieved; and 4, the operation wound is small, and the complication incidence rate is decreased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a self-locking intervertebral fusion fixation device with anterior lumbar approach. Background technique [0002] Currently, posterior methods such as posterior interbody fusion (PLIF) and transforaminal fusion (TLIF) have been widely used in lumbar spine surgery. Lumbar fusion needs to be supplemented with internal fixation to achieve its stability. However, these internal fixation methods also damage the muscles of the posterior spine and spinal joints, thereby increasing surgical trauma, leading to aggravated degeneration and long-term back pain. In addition, the operation space in the rear is limited. In order to avoid nerve traction injury, the fusion cage placed in the area is small, so the restoration of the intervertebral height is not good, and the small contact area may easily cause intervertebral fusion and affect the surgical effect.
