Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a body position fixing device for an operating table. Background Art

[0002] Traditional operating tables only have one bed surface and no position adjustment device. During surgery, the patient's position needs to be adjusted according to the position required by the surgery. For example, when the "human" position is used, the operating table needs to be further tilted to the left or right according to the needs of the surgery to facilitate exposure. At this time, the patient needs to be fixed; for example, when performing surgery on the side of the knee joint, the patient needs to be turned over as a whole. If the legs are turned over alone, it is easy to cause a greater impact on the knee joint surgery; At present, most body position fixation adopts manual fixation, which requires multiple doctors to cooperate with each other. For example, in knee joint surgery, it is necessary to be responsible for fixing the position of the patient's legs and feet, and adjust them as needed during the operation. This method increases the number of people involved in the operation, and the doctor responsible for fixing the position of the patient's legs maintains a posture for a long time, the work intensity is high, and muscle fatigue is easy to occur, which will have a great impact on the stability of the fixation, resulting in a significant reduction in the effect of the operation. At the same time, there are many uncertainties in the use of manual fixation, and factors such as the doctor's technical level and mutual cooperation may affect the effect of the operation. Therefore, a body position fixation device that can adaptively adjust the patient's overall position according to the requirements of the operation is needed.

[0003] The above information disclosed in the above Background section is only for enhancement of understanding of the background of the present application and therefore it may contain information that does not constitute the prior art that is already known to a person of ordinary skill in the art.
