Patella axial x-ray angle photography chair

Abstract

The invention provides an X-ray angle photographic device for axial view patella. The device comprises a seat board, wherein the bottom of the seat board is connected with a support frame; the front side edge of the seat board is hinged with an angle plate; an angle testing mechanism is arranged on the left side edge or the right side edge of the angle plate and is close to a hinged point of the seat board and the angle plate; a backrest is connected with the rear side edge of the seat board; an angle adjusting mechanism is arranged between the support frame and the angle plate. The motion track of the axial view patella can be photographed continuously at the constant speed or the axial view patella can be photographed at the fixed angle through matching of the angle adjusting mechanism and the angle plate, great convenience is brought to accurate diagnosis and treatment of axial view patella pain, the overall structure is simple, and the control is accurate.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a patella axial X-ray angle photography chair. Background technique [0002] In the case of longitudinal fractures of the patella, bone cracks, dislocation of the patella, the measurement of the relationship between the patella and the femoral condyle, and the abnormal patella track, X-ray photography of the patient's patella axis is required. Existing X-ray photography positions are often taken in the prone or supine position. However, due to the knee joint swelling and pain and the inconvenience of position fixation, it is difficult to meet the requirements of the X-ray incident angle or point of incidence, resulting in poor imaging of the patella and femoral joints. Complete or overlapping conditions; at the same time, to facilitate accurate diagnosis, it is often necessary to shoot multiple angles of the patella axis, such as 30 degrees, 60 degrees, 120 degrees, etc., or images of...

AI Technical Summary

Problems solved by technology

The existing X-ray photography positions often adopt the prone or supine position for shooting, but because of the swelling and pain of the patient's knee joint, it is inconvenient to fix the position, and it is difficult to meet the requirements of the X-ray incident angle or incident point, resulting in poor imaging of the patella and femoral joints. Complete or overlapping; at the same time, in order to facilitate accurate diagnosis, it is often necessary to take pictures of the patella axis at multiple angles, such as 30 degrees, 60 degrees, 120 degrees, etc., or images of the entire movement trajectory, and conventional shooting positions cannot meet the requirements. need

[0003] In the prior art, devices such as fixed brackets and angle plates are also used to take X-ray images of different angles of the patella axis, but there are problems such as single function, limited angle selection, inaccurate angle positioning, and inconvenient operation.
