Abstract:
The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.
Abstract:
The present invention relates to an injectable composition for labeling a lesion and a method for providing information on the position of the lesion using the injectable composition. More specifically, the injectable composition for labeling a lesion according to the present invention can include a second composition comprising a biocompatible viscous material in a first composition comprising a complex containing an active ingredient to resolve a problem of rapid settling of the complex. Additionally, in particular, the injection composition for labeling a lesion according to the present invention can have an effect of allowing a predetermined amount of the complex to be injected by resolving the problem of rapid settling of the complex during preparation of the injection, allowing a certain amount of the complex to be injected, and an effect of enabling convenient and stable use thereof for clinical purposes by resolving the problems of injecting an excessive amount of the complex and the quick spread thereof to the periphery.
Abstract:
The present disclosure relates to an augmented reality (AR) image projection system capable of simultaneously capturing a real image and projecting an AR image, and capable of applying same to a subject requiring precise work or in an environment having spatial restrictions. The present disclosure includes a real image capture device for capturing a real image illuminated by invisible rays without interference with visible rays, and an AR image projection device for projecting an AR image, wherein the real image capture device captures a real image and the AR image projection device projects an AR image through the same optical axis. Further, the present disclosure includes a real image capture device, an AR image projection device, as well as additional imaging devices such as a fluorescent camera configured integrally along the same optical axis, and configured to avoid wavelength interference between a light source and an excitation light and the like.
Abstract:
The present invention relates to a fluorescent image system capable of generating white light by mixing three monochromatic lights, i.e. red, green and blue monochromatic lights, having a narrow band wavelength, instead of white light of constant wavelength; providing a fluorescent image-use light source that generates a mixed light by adding a fluorescent excitation light source suitable for fluorescent substances; and photographing a general image and fluorescent image simultaneously with the light sources. The fluorescent image system includes a monochromatic light source to generate white light by mixing red, green and blue monochromatic lights, and a fluorescent excitation light source for fluorescent images; and includes a mixed light source to provide a mixed light which mixes monochromatic light and fluorescent light, and an image photographing device which separates the wavelengths of visible light and fluorescent light in the mixed light, and photographs a general image, fluorescent image and mixed image.
Abstract:
The present invention relates to a labeling composition for a cancer lesion, having a complex in which a pigment for straining living tissues, a radioactive isotope, or a combination thereof binds to macro aggregated albumin (MAA). A method for providing information regarding a cancer lesion site using the labeling composition for a cancer lesion. A labeling kit for a cancer lesion having the labeling composition for a cancer lesion; and a complex in which a pigment for straining living tissues binds to MAA included in the labeling composition for a cancer lesion. The labeling composition for a cancer lesion according to the present invention binds to a cancer lesion to detect a site, size, and the like of the cancer lesion in real time, thereby improving the success rate of a surgical operation for the cancer lesion and also preventing excessive loss of normal tissues.
