Embodiment Construction

[0011] Such as figure 1 Shown:

[0012] One end of the propeller screw 3 is fixedly connected to the knob 10, the other end of the propeller screw 3 is connected to the telescopic rod 9, the other end of the telescopic rod 9 is connected to the cross bar 8, and the other end of the cross rod 8 is connected to the pressure plate 7, and on the outside of the pressure plate 7 Connect the buffer pad 6; the pressure plate 7 and the buffer pad 6 are arc-shaped to meet the requirements of the human body as much as possible and increase the contact surface, and the pressure plate 7 can be made of metal material, but the buffer pad 6 should be as close as possible to the human body due to contact with the human body. It is made of plastic including soft plastic; a pressure gauge is connected between the cross bar 8 and the telescopic rod 9, so that the pressure value of advancing can be observed and recorded.

Abstract

The invention relates to a radiograph fulcrum pressurizer for lateral flexion of vertebral column. The invention has the technical scheme that one end of a propeller screw is fixedly connected with a knob, the other end of the propeller screw is connected with a telescopic rod, the other end of the telescopic rod is connected with a cross rod, and the other end of the cross rod is connected with a pressure plate. The invention solves the defects that standardization is difficult to perform because orthopedic force is not maximized and is instable, and the effectiveness and reliability are reduced. The invention has the effects that: the propeller installed on one side of an examining table enables the metal pressure plate to move forward and continuously pressurize the projecting points of scoliosis through a cushion pad, so that the form of the image of the scoliosis after correction is simulated, and a correction effect similar to that of implantation of an orthopedic material is achieved; the pressure measuring result can realize standardization of the photographical art operation; the pressure cushion pad pressurizes the projecting points of the scoliosis constantly, thus enabling the orthopedic force applied in vitro to be maximized; a patient is protected from compression injury due to too high pressure; and the problems of radioprotection and the like during auxiliary propelling are solved.

Description

technical field [0001] The invention relates to a medical imaging device, in particular to a fulcrum presser for lateral flexion films of the spine. Background technique [0002] Assessment of spinal flexibility can determine the structural features of scoliosis, the extent of fused levels, and predict the effect of correction. By comparing the lateral flexion X-ray films taken in the supine position, the rate of change of the scoliotic Coob angle can be measured and the spinal flexibility index can be calculated. Spine surgery uses orthopedic materials to correct scoliosis in vivo. Therefore, it is necessary to take supine lateral flexion X-rays before surgery to evaluate the degree of correction of scoliosis in order to predict the effect of orthopedics and design a surgical plan. [0003] Before the present invention, the supine and lateral flexion photography of the spine mainly relied on the patient's own lateral bending position, or the help of family members to push ...
