Description
Technical Field
The utility model relates to a human body film detection area that shoots especially relates to a knee joint film device of shooting.
Background
At present, with the accelerated aging degree of China, more and more knee osteoarthritis patients are caused, and the ambitious goal of healthy China is seriously influenced. Knee osteoarthritis progresses to the middle and terminal stages and often requires surgical treatment, including tibial high osteotomy (HTO), unicompartmental joint replacement (UKA) and total knee replacement (TKA). How to accurately evaluate the severity of the knee joint three-compartment lesion of a patient before an operation has very important value for the selection and formulation of an operation scheme.
Preoperative knee X-ray films are crucial for the above mentioned preoperative assessment. Different knee angles of bending, different X-ray piece projection angles and knee joint X-ray pieces under different external forces can provide different imaging information for clinicians, help clinicians to accurately judge the wearing and tearing and the pathological change degree of the three compartments of the knee joint of a patient, can help to judge the reliability of the inner and outer collateral ligaments simultaneously, and then formulate the operation scheme according with the patient. However, most of the current radiographic devices in hospitals are mainly used for photographing the knee joints under the conditions of full extension and extreme flexion, the knee joints of patients cannot be accurately fixed at a certain knee flexion angle for photographing, and the projection angle of X-rays during photographing cannot be adjusted, so that the actual help of clinicians is very limited, especially for orthopedics doctors.
In addition, how to judge the integrity and reliability of the medial and lateral collateral ligaments before the knee joint operation is also very important. Knee surgery often requires that the collateral ligaments have good integrity, without loosening or even breaking. Before operation, the tension degree of the collateral ligaments is reflected by the X-ray film of the stress position of the inversion or eversion of the knee joint, namely, the inward or outward external force of the knee joint is continuously applied during shooting, whether the gap between the inner joint and the outer joint on the X-ray film is widened or not is observed, and if the gap is widened, the ligament on the side is loosened or even broken. However, at present, when performing X-ray photography at stress positions of inversion or eversion of the knee joint, a patient generally lies on a photography table in a prone position, and an attendant or a technician can manually apply stress to the knee joint of the patient according to the photography requirement. There are three problems with this: 1. the magnitude and time of the applied force cannot be accurately quantified, and the repeatability is poor; 2. the force application size and angle are not easy to control, the applied force is small, the duration is short, the requirement of stress position cannot be met, and a false negative result is caused; 3. manual operation, more radiation exposure.
Therefore, there is a need for an auxiliary tool for knee joint X-ray radiography serving clinicians and radiology technologists to obtain X-ray films of knee joints under different knee bending angles and different stress conditions, so as to obtain more accurate preoperative imaging information.
