Minimally invasive and minimally invasive techniques are one of the major developments in modern surgery, and the prerequisite for effective implementation is the correct determination of the surgical incision. Generally, surgeons use more anatomical markers on the surface of the human body to perform positioning, but this method has poor positioning accuracy due to differences of patients and experiences of operators, and is difficult to meet the requirements of minimally invasive and minimally invasive techniques on accurate positioning.
X-ray examination is the most common clinical examination method, and can reveal the internal anatomical structure of the human body and the location and form of a specific lesion or foreign body. With X-ray examination, an important reference can be provided for the location of the surgical incision. However, the fluoroscopic image of the X-ray examination lacks positioning information to be projected on the body surface. Due to the influence of factors such as perspective angle, magnification, experience difference and the like, surgeons are difficult to accurately position incisions and entry points of minimally invasive and minimally invasive operations through X-ray films.
In the operation and operation process, the deviation of the incision positioning often leads to the fact that the operation incision has to be prolonged in the operation, and the operation wound surface is enlarged to obtain the ideal exposure effect. This can increase the surgical trauma of the patient, prolonging the post-operative healing time; repeated X-ray irradiation for precise positioning of the incision during surgery increases the radiation exposure of the patient and the operating personnel, affecting the healing of the soft tissue in the exposed surgical area;
