technical field

The utility model relates to the technical field of medical devices, in particular to a lumbar vertebra body position pad.

Background technique

Spinal decompression, fixation and fusion are the classic and basic surgical methods of spinal surgery, and have reliable and definite curative effects on spinal degenerative diseases, spinal deformities, spinal tumors and other diseases. Due to the development of pedicle screw technology and its unique advantages, posterior approach surgery has become the most commonly used approach for the treatment of spinal disorders in my country, so there is an incision behind the trunk. Because general anesthesia is used in conventional open spine surgery, the surgical grade is high, and the surgical trauma is relatively large. Therefore, in the early postoperative recovery process, the bed rest time is prolonged, the free movement is limited, and the time should not be too long, which has become a routine rehabilitation transition. stage.

During bed rest, patients are generally more receptive to the supine position, so this position is the position that has been used for the longest time. When the patient after spinal surgery is in the supine position for a long time, the long-term pressure of the incision can easily lead to poor local blood circulation and affect the healing of the incision; and local edema leads to increased incision tension and incision skin tension blisters. Fixtures, metal objects can also cause local pain on the soft tissue compression.
