Abstract

The invention discloses a portable shooting auxiliary device for a knee joint axial position X-ray film. The device comprises a horizontal bottom plate, a support, a thigh placing plate, a shank placing plate, a lifting structure and a foot hooking frame. The support is fixed to the horizontal bottom plate; the thigh placing plate is hinged to the shank placing plate; and the hinged position of the thigh placing plate and the shank placing plate is fixed to the top of the support. The end, away from the hinged position, of the thigh placing plate is fixed to the horizontal bottom plate; and the shank placing plate is connected with the lifting structure fixed to the horizontal bottom plate. The foot hooking frame is arranged at the end, close to the shank placing plate, of the horizontal bottom plate. When the device is used for shooting a knee joint axial position X-ray film, the body position of a patient during film shooting is adjusted according to the individual size of the patient and different anatomical forms of patella, so that a standard knee joint axial position film is shot. The device being portable one does not occupy a large space and can be used directly after beingplaced on a physical examination bed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a portable auxiliary device for photographing knee joint axial X-ray films. Background technique [0002] The knee joint is the most complicated joint in the human body. Due to the particularity of the position between the patella and the femur, when the patella is fractured, dislocated, or patellofemoral joint osteoarthritis and other lesions occur, the patella axial view is necessary for routine knee joint anteroposterior and lateral views. supplement. In the past, the patellar axial photography method required high requirements for the patient's body position, or the projection angle was difficult to grasp, which often caused discomfort in the diseased knee joint of the examinee and poor image quality. Through previous work practice, it is very necessary to improve the mold and projection method used for the patella. [0003] The existing knee joint X-ray...
