A surgical placement device that is convenient for placing the patient's body position

technical field

The invention relates to the technical field of surgical placement devices, in particular to a surgical placement device that is convenient for placing a patient's body position.

Background technique

Medical equipment is the basic condition for continuously improving the level of medical science and technology, and it is also an important symbol of modernization. Medical equipment has become an important field of modern medical care. The development of medical care depends to a large extent on the development of instruments, and even in the development of the medical industry, its breakthrough of bottlenecks also plays a decisive role. Medical devices refer to instruments, equipment, appliances, materials or Other items, also including required software.

In knee joint surgery, a knee joint surgery body frame is often used, because doctors in the early stage require the patient's legs to be passively fixed in different positions when performing surgery on the patient, because there is no special assistance in the prior art. The tool can fix the knee joint in an ideal position, so the assistant doctor needs to fix it manually during the operation, which not only increases the work intensity, but also easily leads to mistakes in the operation. However, the currently used knee joint surgery posture frame is too simple in terms of adjustment. Generally, it can only be adjusted up and down, and there is no rotatable adjustment in line with human joints, and it cannot support the patient's legs in a large area, which is easy to cause pressure ulcers in patients. , and the body position frame that supports the patient's leg in a large area has a gap in the adjustment position, which leads to the unsupported part of the patient's leg, which leads to congestion and itching in the unsupported position of the patient after a long time, which is especially reflected in The position of the buttocks of the human body is not conducive to the operation of the operation.
