Description

An operating bed lifting device

technical field

The utility model belongs to the field of surgical tools, in particular to a lifting device for an operating bed.

Background technique

In response to different surgeries, the common operating bed has been updated many times and can be placed in a variety of positions, such as prone position, lateral position, supine position, floating position and so on. At present, carbon fiber operating beds have been designed abroad to deal with some special surgical positions, but they are still not suitable for operations that require special positions.

Ankylosing spondylitis is a disease characterized by inflammation of the sacroiliac joints and spinal attachment points. Strong association with HLA-B27. It is a chronic inflammatory disease characterized by fibrosis and ossification of the large joints of the limbs, as well as the annulus fibrosus of the intervertebral disc and its adjacent connective tissue, as well as ankylosis. In severe ankylosing spondylitis, the patient's spinal joints and sacroiliac joints are rigid and deformed, and even the patient's body becomes a "ji" shape, which increases the difficulty of the operation. Similarly, how to place the surgical position is also a serious problem. Generally, the routine posterior spine surgery adopts the prone position, elevates the thorax and the ilium, and suspends the abdomen in order to reduce the pressure in the abdominal cavity, thereby reducing the amount of bleeding in the surgical field. However, for patients with severe ankylosing spondylitis who are operated on a conventional operating bed, currently only various types of cushions or other devices can be used to fill the suspended part of the "ji" type patient, and the abdomen cannot be suspended to reduce the bleeding in the surgical field; It is easy to cause pressure ulcers in patients; the height of the filler cannot be changed at any time according to the operation of the operation. The doctor on the operating table and other medical workers under the operating table must lift the patient together to complete the work, and the filler needs to be added or extracted manually. It is easy to contaminate the operating table during the whole process, resulting in adverse consequences.
