Abstract

The digital foreign matter position finder mainly comprises a high-voltage generator, an X-ray tube, a collimating device, an image amplifier, a digital CCD, a computer digital image-forming system, an image display and a mechanical support bracket, wherein the image amplifier is provided with a digital CCD at the rear end, the digital image-forming module control the digital CCD to perform signal acquisition and input the signal to the digital image-forming device for real time treatment, and the treated signal is transmitted to the image display for displaying.

Description

technical field [0001] The invention relates to a medical device, in particular to a digital foreign object locator for detecting and locating foreign objects inside human tissues. Background technique [0002] In the past, the traditional localization methods for foreign bodies at home and abroad mainly include: 1. Anteroposterior and lateral methods: according to the anteroposterior (i.e., anteroposterior or posteroanterior) observation of metal foreign bodies located on the inside or outside, and lateral observation of metals located on the ventral or dorsal side In some cases, judge the position and depth of the foreign body, and make skin marks for surgical removal. Generally, it is necessary to use a combination of fluoroscopy and radiographs to achieve accurate positioning; For removal, first turn the patient under fluoroscopy to find the point closest to the body surface of the foreign body, then carry out local disinfection and anesthesia, th...
