C-arm imitating mechanism

Abstract

The invention relates to the field of medical teaching aids, and in particular, relates to a C-arm imitating mechanism. The C-arm imitating mechanism comprises a linear transmission mechanism, a C-shaped transmission shaft, a rotating mechanism, a camera fixing bracket, a camera object distance adjusting mechanism, a camera and a control box; one end of the rotating mechanism is connected with thelinear transmission mechanism through a bottom plate and can do linear motion through the connected linear transmission mechanism, and the other end of the rotating mechanism is further connected with the C-shaped transmission shaft and drives the C-shaped transmission shaft to rotate. The camera can be driven by a series of electromechanical devices to simulate the operation effect of DSA radiography equipment, C-arm operation training and radiography practice can be conducted by means of the device, and the device is low in cost and stable and reliable in long-term operation effect.

Description

technical field [0001] The invention relates to the field of medical teaching aids, in particular to a C-arm imitation mechanism. Background technique [0002] DSA (Digital subtraction angiography) is an advanced X-ray diagnostic technology that is processed by an electronic computer. It is another major breakthrough in X-ray diagnostic technology after CT. It is mainly used in the diagnosis and treatment of systemic vascular diseases. The equipment used by DSA is the C-arm, and its main clinical applications are: 1. Examination of the head and neck vascular system: for cranial space-occupying lesions, arteriovenous malformations, cerebrovascular occlusion, carotid artery stenosis, occlusion, arterial Atherosclerosis and ulcers, etc., can provide diagnostic basis; 2. Examination of the thoracic vascular system: DSA has a better display effect on the heart and great vessels, and is used for the diagnosis of congenital heart disease, valvular disease, cardiomyopathy, and coron...

Problems solved by technology

[0003] The C-arm is a multidisciplinary product of electromagnetics, computers, automatic control, medicine and structural design. The training and C-arm operation training are undoubtedly a big limitation. In this case, in order to meet the medical needs for C-arm operation training in interventional surgery, it is necessary to simulate the C-arm and drive the imaging equipment to move around the human body. , and can position the imaging device to a specific observation position. The current similar mechanism can only realize the linear motion of the imaging device or the rotation at a fixed point, which cannot satisfy the effect of simulating the movement of the C-arm
