Lying position load-bearing CT simulation device and method

Abstract

The invention discloses a lying position load-bearing CT simulation device and method, and relates to the field of medical equipment. The device comprises a push plate, a soft cushion bottom plate, amovable pedal, a large hydraulic cylinder and a small hydraulic cylinder, wherein the push plate is perpendicular to the soft cushion bottom plate; the large hydraulic cylinder is used for driving thepush plate to translate relative to the soft cushion bottom plate; a hinged support is fixedly arranged on one side of the push plate, one side of the movable pedal is hinged to the hinged support, and the small hydraulic cylinder is used for driving the movable pedal to overturn relative to the push plate. The method comprises the steps of firstly collecting target data when a patient stands, and carrying out closed-loop control on the action of the large hydraulic cylinder and the action of the small hydraulic cylinder according to the target data in the simulation process, thereby completing automatic simulation. According to the device and the method disclosed by the invention, more accurate simulation can be carried out through automatic control and adjustment, accurate diagnosis data can be obtained, and the control is convenient; and when the diagnosis is simulated, the patient can directly adopt a lying posture, and the application range is wide.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a lying position load-bearing CT simulation device and method. Background technique [0002] In the treatment of foot and ankle surgery, in order to accurately diagnose foot and ankle related diseases and formulate surgical plans, CT scanning technology is often introduced to observe the foot and ankle conditions. However, traditional CT scans are performed in a non-weight-bearing state, which cannot simulate the physiological weight-bearing state when standing on the foot, which will cause certain deviations in the diagnosis of diseases. In response to this problem, a series of weight-bearing simulation devices have appeared, but these devices often only apply pressure to the soles of the feet, and cannot completely simulate the force state of the patient when standing, and cannot accurately obtain diagnostic results; and their The degree of automation is low, and the simulatio...

Problems solved by technology

However, traditional CT scans are performed in a non-weight-bearing state, which cannot simulate the physiological weight-bearing state when standing on the foot, which will cause certain deviations in the diagnosis of diseases.

In response to this problem, a series of weight-bearing simulation devices have appeared, but these devices often only apply pressure to the soles of the feet, and cannot completely simulate the force state of the patient when standing, and cannot accurately obtain diagnostic results; and their The degree of automation is low, and the simulation control is inconvenient; at the same time, the structure of such devices is usually relatively simple, and the patient cannot adjust the posture in time during the simulation, and it is impossible to achieve accurate simulation for some patients who are difficult to maintain a sitting posture
