Description
Technical field
The utility model relates to medical device field, especially a kind of black light for operation shows equipment and optics
Instruct system.
Background technique
Iconography equipment in medical surgery can help doctor to obtain the information that naked eyes can not observe directly in time,
Carry out the imagings such as X-ray, nuclear magnetic resonance, CT before the surgery or in the process to judge surgery location, angle and depth, though it can provide
Accurate morphologic information, but with the process of operation, anatomical structure changes, and preoperative image information is difficult to continue to instruct
Operation.Moreover, because radiological imaging will cause ionization damage to doctor and patient, while imaging technique and equipment valuableness are stupid
Weight, it is difficult to be integrated with surgical procedure.These factors limit radio nuclide imaging, positron emission computerized tomography, single photon emission
Application of the imaging modes such as computerized tomography and magnetic resonance imaging in art in navigation/guidance.So a very long time faces
Bed operation still relies primarily on the identifying by naked eye lesion and normal tissue of operative doctor, cause to operation doctors experience it is serious according to
Rely, lacks specific objective standard.
Therefore clinically system is instructed to have urgent need real-time operation optics.With near-infrared fluorescence imaging technology
Development, near-infrared fluorescence imaging technology navigation/guidance become the hot spot of current development.Presently, there are studied using near infrared light
The system of picture has been used to clinical guidance operation, and naked eyes can be provided for operative doctor or operation microscopy apparatus is difficult to the light distinguished
Learn information, and have imaging sensitivity, high resolution, it is easy to operate the features such as, gradually by surgical favor, but there are still
Some problems have to be solved.
Near-infrared fluorescence imaging technology has been demonstrated there is very low tissue scatter, and bigger penetration depth, low is self
Fluorescence background is capable of providing the higher image of resolution ratio in practical applications.But since near-infrared (760nm-1mm) function indicates
Property fluorescence it is fainter, and naked eyes it is invisible, therefore realize near-infrared function fluorescence imaging need using sensitive refrigeration mode it is close
Infrared camera carries out the acquisition of image, and on the screen by image real-time display.In order to compared with morphology White-light image, also often
By this two kinds of image split screens or fusion display on large screen, as shown in Figure 1, so that surgeon observe in art, instructs to swell
Tumor excision or other surgical procedures.In Fig. 1,01 is infrared camera, and 02 is general camera, passes through infrared camera 01 and common phase
Machine 02 is imaged respectively to be shown side by side or additive fusion is shown.
But visually observe the visual field there are difference with doctor since screen is shown, and doctor need in art constantly screen with
Operative region switching, the error between the image for be easy to causeing screen to show and the actual operation operation visual field, it is difficult to increase operation
Degree also extends valuable operating time.
Insider further researches and develops wear-type imaging device, and near-infrared function image real-time display is shown device in head,
Part solves the problems, such as this.Doctor, which rotates eyeball, can be completed the comparison of image Yu surgical procedure region.Although this is in certain journey
Solve the problems, such as constantly to switch in screen and operative region on degree, but still need to patient repeatedly by screen picture and operative region it
Between image be compared, and additional head can be brought to bear a heavy burden to doctor, the visual field of doctor be limited, to the flexible of surgical procedure
Property is adversely affected with accuracy.
