Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to plantar pressure collection system when being used for heavy burden CT of foot simulation.
Background
At present, the diagnostic and evaluation effects of imaging examination technologies such as CT, MRI and the like on orthopedic diseases are highlighted gradually. For ankle deformity (such as flat foot, high arch foot, hallux valgus, etc.), it is important to maintain the examination of the foot under the state of load. The foot weight at CT is more difficult to achieve than weight X-ray. Because the patient can only assume a flat position due to the limitations of the CT machine, it is difficult to require the patient to maintain a foot load in an upright position. Arch collapse is more pronounced in soft, flat-foot patients when they are under load, and if the foot deformities may not be apparent from the acquisition of CT under non-load conditions, deviation in their diagnosis and assessment may occur.
The foot simulation load needs to reflect the sole stress condition when the foot is actually standing, namely the distribution of the ground reaction force. Conventional weight-bearing devices, particularly active compression devices, only focus on the overall force exerted by the foot and do not accurately reflect the actual force exerted by various areas of the foot. Thus, there are large variables in the implementation of such pressurization measures. The foot may be unevenly stressed and it is difficult to use these devices to finely analyze foot bone motion.
Application No. 201520310093.8 proposes an orthopedic human foot simulated weight test device, which comprises a base, a vertical foot supporting plate, a pressure scale, a seat slide and a pressurizing device, wherein the pressure is applied through the sole until the value of the pressure scale is equal to the total counter force when the patient stands, and the simulated foot load is considered to be approximately in a physiological state and in a vertical state. Practice has shown that the above-mentioned device has the following disadvantages: (1) when the foot is used for simulating load bearing, the total pressure of the sole is consistent with the counter force when the user stands, and when the user simulates the foot load and carries out CT scanning, the subjective inversion, eversion, or dorsal extension and plantar flexion of a subject can cause the pressure of the sole to be distributed on the inner side, the outer side, the front foot and the rear foot and generate larger difference when the user stands; (2) the dorsal extension, plantar flexion or inversion and eversion under the foot load cause the bone joint position inside the foot collected by the simulated load CT to be inaccurate, and cause the deviation of subsequent diagnosis and treatment. For example, a soft and flat foot patient may have heel eversion when standing upright, and when CT acquisition under simulated weight is performed, if the compression is concentrated on the outer side of the foot, the calcaneus will have a certain tendency to evert compared with the heel when standing upright, and the final CT image will have a reduced degree of eversion reflecting the calcaneus, which is also disadvantageous for subsequent diagnosis and treatment.
Therefore, an accurate and intuitive plantar pressure acquisition device for simulating the foot load CT is needed.
