Abstract

The invention discloses a distraction reduction device for an anterior cervical surgery and a using method thereof. The distraction reduction device comprises a sliding rod, a limiting rod and a vertebral body fixator, wherein the sliding rod is in sliding connection with the limiting rod, and the sliding rod and the limiting rod are fixedly connected with the fixator through an L-shaped supporting rod; the vertebral body fixator comprises two bearing plates arranged side by side and a connecting plate connected with one ends of the two bearing plates; fixing blocks are arranged at the other ends of the bearing plates, and the bearing plates, the connecting plate and the fixing blocks form a U-shaped structure. The distraction reduction device is used in cervical vertebra joint noose distraction reduction in an anterior cervical vertebra operation, can be used for fixing and lifting vertebrae for reduction, has small operation trauma, and is favorable for postoperative recovery.

Description

Technical field: [0001] The invention relates to the technical field of surgical instruments, in particular to a distraction reduction device for anterior cervical surgery and a method of use thereof. Background technique: [0002] Anterior cervical surgery is often used in the treatment of cervical degenerative diseases, cervical fractures and other diseases. Anterior cervical distractors are widely used in anterior cervical surgery. The two vertebral bodies expand the soft tissues such as skin and muscles and the intervertebral space to facilitate the operation. However, since the cervical vertebrae belong to the deeper tissues of the human body, and human muscles have good elasticity, after the cervical vertebrae are opened with a spreader in minimally invasive surgery, the muscles will still block the doctor's field of vision. The method for solving the above problems in the prior art is that several assistants use pull hooks to pull the skin and muscles around the woun...
