The present invention relates to the field of dental diagnosis and treatment technologies, and in particular, to an image enhancement system of an operating microscope and an implementation method therefor.
Modern medicine has made substantive progress in the fields of in vitro diagnosis, micro treatment, medical imaging, minimally invasive treatment, and the like, and diagnosis and treatment means of cross-category and multidisciplinary integration are emerging. Due to the continuous development of medical imaging devices and the rapid development of medical imaging technologies, sub-disciplines of medical imaging such as CT, MR, interventional radiography, ultrasound, and nuclear medicine are gradually established, and a medical imaging technology discipline is also gradually formed.
Medical imaging information is more sensitive, intuitive, specific, and early-stage. Image analysis develops from qualitative to quantitative, and from displaying diagnostic information to providing a surgical path solution. Image camera and display develops from two-dimensional simulation to three-dimensional full digitalization. Image storage develops from film hard copy to soft copy without film, and even image transmission networking; and from a single image technology to an integrated image technology.
To adapt to the digitization, networking, and integration of medical imaging, it is necessary to establish a viewpoint of integrating three majors of diagnosis, technology, and engineering. A single major can no longer complete the functions of the modern medical imaging discipline.
Root canal therapy is used as an example. A doctor needs to completely open a pulp cavity, and find and treat all root canals. A human being generally has one to four root canals per tooth, with a rear tooth having the most root canals. When a root canal orifice of a multi-root canal tooth is difficult to find due to a case such as age-related changes or deposition of reparative dentine, pulp stone, pulp cavity calcification, or root canal morphological variation, an anatomic form of the pulp cavity should be understood and viewed from all directions and positions with the aid of the three-dimensional anatomic form of a tooth. Quantities, shapes, positions, directions, and bending of roots and root canals, a relationship between a root of tooth and a dental crown, and various variation conditions of anatomic forms of the root of tooth and the root canal are learned and pointed out by using X-ray films captured by using a multi-angle projection method. Because a quantity of root canals in some teeth may reach four, there may be complicated cases such as lateral canals, accessory root canals, apical ramification, and apical bifurcation, which may be missed even under magnification observation. It is necessary to estimate a possible position of the root canal. If necessary, a small ball drill may be used to remove a small amount of dentin at a developmental groove where the root canal may or is expected to be located, then a sharp probe may be used to attempt to pierce any calcified region to indicate dentinal collar with a tooth neck being removed in a root canal orifice to expose a position of the root canal orifice. That is, if there is calcification in the root canal orifice and the like, it is more necessary for a doctor to repeatedly explore each possible position, which inevitably removes too much healthy tooth tissue.
At present, a manner of preoperative dental film is often used to help a doctor judge and determine a quantity and shapes of root canals. First, the doctor needs to pay most attention on remembering the shapes of the root canals, and even suspend the operation to observe the dental film again. In addition, because the tooth film is only a two-dimensional planar image, a three-dimensional shape of the root canal cannot be accurately reflected. In fact, a plurality of root canals are bent for a plurality of times, and cannot rely on the tooth film for accurate positioning.
CBCT and other three-dimensional images are complex and difficult to remember. The doctor needs to remember a three-dimensional shape of a tooth structure, and take a lot of effort to compare, stack, and fuse the three-dimensional shape with a real object under a microscope during operation, which is difficult to ensure accuracy and precision.

The media signal processing apparatus may be a computer independent of the microscope, or may be a part of the microscope, or may be a mobile terminal with a touch screen such as a touchscreen mobile phone or a tablet computer.

The media signal processing apparatus 4 processes image data of the target tooth to obtain an optimal path for operating the target tooth, and then selectively display the position information of the surgical instrument and relative position information between the surgical instrument and the optimal path in the information display region of the display device 21. For example, position information of the handpiece (the dental drill) may be displayed in a window in the information display region. Alternatively, position image information between a path point and the handpiece (the dental drill) is displayed in a window in the information display region, to prompt the operator whether a head of the handpiece (the dental drill) deviates from the path point.

A quantity, a size, a position, a direction, and an angle of the superposed information superposed in the field of view region of the eyepiece may be all adjusted as required, to adapt to different habit requirements of operators. The superposed information superposed in the field of view region of the eyepiece may be directly adjusted through a handle, a mouse, a keyboard, or the like, or may be controlled by acquiring biometric feature information such as user voice, a gesture, a facial expression, an eyeball action, a brain nerve wave, and a shape of a mouth, so that the operator completes an operation without a touch skill, and the operation is simple and quick. A region displayed in the display device other than a region in which the superposed information needs to be superposed is displayed in black. In this way, during optical path observation of the binocular tube 3, the image in the main optical path of the microscope body can be observed, and the image displayed in the display device can also be observed. Root canal therapy is used as an example, a slice image of CBCT of a tooth and a real image in the main optical path of the microscope body may be calibrated and then superposed and displayed, so that a highlighted dental pulp hole image may be superposed on a real tooth image, which greatly facilitates operation positioning for a doctor, reduces an operation difficulty, and improves operation accuracy. In combination with a positioning and navigation device, a surgical instrument can be positioned in real time, thereby further improving the operation accuracy.
