Handheld fluorescent image navigation positioning device

Abstract

The invention discloses a handheld fluorescent image navigation positioning device which comprises a handheld shell (1), a power module (2), a micro-projection module (3), an image acquisition module(4), an image processing module (5), an excitation light source module (6) and a distance measuring module (7). According to the device, pathological tissues are developed by the aid of a near-infrared fluorescent imaging technique, ICG (indocyanine green) serves as a contrast medium, acquired fluorescence images directly project to corresponding diseased regions by a real-time projection mode, and projection positions and projection sizes are calibrated by the distance measuring module in real time. Compared with an existing development mode, fluorescent images of the tissues can be more visually observed, the device has higher fluorescent efficiency and better dynamic properties, the whole device is highly integrated as a handheld device, and the device is convenient to operate, can be used for clinical operation and has a good practical prospect.

Description

technical field [0001] The invention relates to the technical field of medical imaging and medical equipment, in particular to a hand-held fluorescent image navigation and positioning device. Background technique [0002] At present, due to the limitation of surgical equipment, equipment and technology, traditional medical surgery relies heavily on the clinical experience of doctors, which not only increases the work intensity of doctors, but also causes relatively large randomness in the accuracy and success rate of surgery. [0003] With the development and innovation of medical imaging technology, image processing technology and other technologies, in recent years, surgical operations are developing in the direction of precision, accuracy and speed. The surgical navigation system is a new type of surgical auxiliary equipment developed during this process. The basic principle of this type of equipment is to process medical images such as PET, CT, MRI, and fluorescence (suc...

Problems solved by technology

Among them, the common optical axis imaging projection navigation device adopts the common optical axis design of image acquisition and projection. Such a design cannot achieve simultaneous focusing of the imaging optical path and projection optical path, or can only achieve clear focus of the acquisition and projection images by focusing separately. , Relying on the recognition with the naked eye brings projection errors and consumes a lot of operation time

And in order to ensure the coaxial system, the optical path of these coaxial systems is complicated, and most of them are large desktop products, which are inconvenient to use and operate.

[0006] In order to solve the above-mentioned clinical problems, some surgical projection navigation devices designed with parallel optical axes have been developed, such as the Chinese patent "a breast cancer imaging projection navigation system" (patent application number: 201420339875.X) and "a A Projection Navigation Device for Imaging Lesions” (patent application number: 201510068823.2). This type of projection navigation device parallel to the optical axis has a simple optical path, small device size, and high fluorescence efficiency. However, when the working distance of the device changes, the projection pattern cannot Real-time accurate registration with real biological tissue, the base design also has certain limitations on the doctor's operation
