Description

Spinal operating table

Technical Field

The invention relates to the technical field of spinal surgery devices, in particular to a spinal operating table.

Background

97% of middle-aged and elderly people in China have spine diseases, and in recent years, the spine disease trend is younger, in people under 40 years old, more than 40% of people have various diseases, and the incidence rate of scoliosis of children is more than 25%. The domestic spine diseases not only spread widely in middle-aged and elderly people, but also gradually spread to teenagers and children, and more people enter hospitals due to the spine diseases. The spine lateral curvature and other symptoms of the teenagers can be physically corrected by means of physical traction, bracket fixation and the like, while the spine diseases of the adults and the old cannot be corrected simply by means of physical means due to long suffering time, the elderly patients and the like, and at the moment, surgical treatment becomes the first choice for the middle-aged and the elderly patients with the spine diseases. With the increasing aging of the population in China, more and more middle-aged and elderly people suffer from spinal diseases, and the increase of patients year by year brings great working pressure to limited medical care personnel. Therefore, improvement of the existing medical equipment is urgently needed to improve the working efficiency of medical staff and reduce the labor intensity of the medical staff through mechanical assistance.

At present, in the operation process of a hospital, a patient with a spine always needs to turn over after going up an operating table and then turns over from supine to prone, and when the mode is solved, the patient can be manually turned over after being transferred to the operating table from a sickbed by the existing doctors and nursing personnel, and the mode needs to be operated by a plurality of nursing personnel or doctors together, so that time and labor are wasted, and the injury of the patient is easily aggravated. If the structure commonly used by the existing turn-over sickbed is adopted, the following defects exist:

1. the manual turning-over type is inconvenient to use, the labor capacity of medical personnel is large, and a patient is easy to be injured when turning over;

2. the electric turnover type matching equipment occupies large space and is inconvenient to maintain, and the patient needing the operation is easy to suffer secondary injury;
