Description

C-arm structure and medical equipment Technical Field The application relates to the technical field of medical equipment, in particular to a C-arm structure and medical equipment using the C-arm structure. Background Digital subtraction angiography (Digital SubtractionAngiography, DSA) equipment is a core medical equipment for vascular disease diagnosis and treatment, wherein the structure of a C-arm is important, and the opposite sides of the C-arm are respectively connected with an X-ray tube and an image receiver and can rotate 360 degrees around a patient examination part, so that vascular images of different angles are acquired. However, during the movement of the C-arm, the tip is very prone to collide with the catheter bed, and once the tip collides, structural deformation, electronic component damage and the like of the C-arm may occur, and a cascading failure of the equipment system may also be caused, so that the overall diagnosis and treatment performance of the equipment may be affected. In the related art, two technical means are mainly adopted for preventing the collision between the end head of the C-arm and the catheter bed. One is to calculate the relative position relationship by software, and calculate the relative distance between the C-arm end and the catheter bed by setting specific points, so as to judge the collision risk. The other is to adopt a capacitive anti-collision structure, and the collision is pre-warned according to the capacitance value change caused by the distance change between the C-arm and the catheter bed by utilizing the capacitive induction principle. However, in the first anti-collision means, the calculation based on the set point has a monitoring blind area, so that the collision danger in the blind area cannot be timely perceived, and in the second anti-collision means, the capacitive anti-collision structure is seriously interfered by external environment factors due to sensitivity, so that effective early warning is difficult when the collision is actually faced. Disclosure of utility model The embodiment of the application provides a C-arm structure and medical equipment, which can accurately and timely judge whether a C-arm end is collided or not, and can prevent the C-arm end structure from being damaged to a certain extent through the arrangement of an elastic buffer assembly, so that the overall diagnosis and treatment accuracy of the medical equipment can be improved.
