BY Ben Yoo, Sung Shim, Won Joo Woo, and Young Han

BACKGROUND OF THE INVENTION

The present invention relates to a method of dental microscopic procedure, which enables dentists to perform dental procedures including surgery by seeing the images on a screen, and not looking into a small eyepiece. Furthermore, this invention relates to a method of dental microscopic procedure, which makes recording and manipulating images obtained from the digital surgical microscope, an image data taking device more convenient. Current variations of the microscope disrupt the surgery process and do little to improve the quality, efficiency, safety, and comfort of surgical procedures. Today, many dentists use microscopes, limiting mobility, and causing neck, shoulder, and eye strain. Other telescopic microscopes require the dentist to adjust and constantly focus the scope to get an adequate image, interfering with the process of surgery and lending unnecessary difficulties during the operation. Should the dentist or the patient move, or if the scope gets displaced, relocate the image, then the image becomes blurry and requires one to refocus.

The present invention will relieve the user of the constant need to refocus due to its broader range, and will rid the user of the physical challenges posed by the current market of microscopes such as: eye, neck, shoulder and back strain.

Additionally, the digital surgical scope (DSS) offers tools and devices to improve future dental procedures and

surgeries. The digital surgical scope offers a magnified (combined optical and digital zoom) high quality display of the surgery, as it happens in real time; while the imaging software allows the recording of streaming video and capturing of snap shots during surgery.

Unlike prior microscopes, the digital surgical scope is all-inclusive, offering the previously unavailable convenience of its all-in-one combination which includes: patient management, image processing software, in-line light illumination assembly, video camera unit, computer and monitor. ,

In addition the digital surgical scope is also unique in that it is highly maneuverable. It can be moved in virtually any direction and/or angle, unlike traditional scopes that are much more limited in directional/angle maneuverability .

Also, the digital surgical scope uniquely offers a realistic depth of field. Currently, available microscopes with attached video camera can only display a limited depth of field; thus making the practice of dentistry with the traditional microscope much more difficult. The depth of field of the digital surgical scope allows the dentist to see better while performing more difficult operations.

The ^" digital surgical scope method is unique in that it offers digital enhancement to the image, allowing for much greater magnification than traditional scopes. For instance, 12Ox (combining optical and digital zoom) versus a maximum of 40x with traditional scopes.

The imaging software allows the user to record images either in a streaming video or photo snapshot directly to the patient's database. No other equipment sold today allows this function.

The dentist need not peer into a scope to perform procedures; instead, he/she can sit comfortably and view his/her work with more magnification on a monitor. He/she can also share this view with the patient or staff. A split screen allows one to view various types of images including: photos and streaming video, simultaneously.

Traditional equipment limits the dentist. With a loupe and headlight he/she is tethered to the cord by the headlamp, resulting in poor ergonomics.

According to a published study, "80% of dentists suffer from chronic back and neck pain." The digital surgical scope will relieve the dentist from neck, back, and eye strain by allowing him/her to sit upright and giving more freedom to move. No other dental microscopic device on the market today can make that claim.

Accordingly, a need for a digital surgical scope has been present for a long time. This invention is directed to solve these problems and satisfy the long-felt need.

The process of browsing the history of patient includes bl) showing all images in thumbnail format; b2) showing the digital surgical microscope image and X-ray images; b3) showing the comparison of the digital surgical

scope. video image and the X-ray image; b4) comparing images by selecting multiple images and multi-viewing; and b5) presenting a case for patient by selecting multiple images to present a possible treatment plan or treatment result from previous problems .

The digital surgical scope utilizes the best digital technology to improve upon the microscope. The current invention allows for a digital camera, which is placed at a distance of 2~20 inches from the patient' s mouth, to capture the streaming live video image of any dental procedures/surgery to be displayed on one or more monitors in high resolution with adjustable magnification, optical zoom and digital zoom combined, during the dental procedure and surgery. Dentists can record the streaming video images in the built-in hard drive, with the computer software database, or an optional external driver or a DVD recorder, for clinical charting, future referencing, training, documentation, or other uses. The streaming video can be displayed in multiple monitors in different locations/rooms and can be transmitted to a streaming video broadcast via the internet.

The invention includes the transfer of the image with the adjustable magnification and the display of the live/streaming intraoral image on the monitor during the dental procedure/surgery. The camera head, can be kept outside of the mouth at least 2-20 inches away from the mouth .

The advantages of the present invention are: (1) the method and system of dental microscopic procedures does not require a dentist to peer into a stationary eyepiece of the microscope so the dentist can view the area of interest displayed on a screen in comfort; (2) the system of the

invention magnifies the image many times more than traditional microscopes and loupes with the addition of digital enhancement; (3) with the system of the invention, the dentist does not have to refocus when the patient moves in the chair. The field of view is large that repositioning the area of interest, refocusing is not necessary. With traditional scopes and loupes, the field of view decreases with magnification, and work must cease while the dentist refocuses for each slight movement. Additionally, in order to focus on a different area of interest while zoomed in, the dentists must first zoom out, identify the area of interest, zoom back in, and refocus. By contrast, the system requires no extra steps, only minimal adjustment is needed; (4) the image processing and management software of the invention allows the dentist to take photos, or stream video , and save them directly to the patient's digital file, within the patient database. These files are saved on the included hard drive or an optional external drive, with almost no effort and no interruption in the procedure. With a click of the button, or foot pedal, the dentist saves the still image or the streaming video, whichever he chooses, or both, to the built-in computer or an optional external drive connected to the USB port or other method such as firewire and so on. No other scope available today can offer that feature which provides for better documentation of procedures and updating patient's charts; (5) the system is able to display the surgical scope images and X-ray images together, side-by-side, on a split screen, this provides for a better diagnostic tool; (6) the system has the capability of displaying streaming video or recorded images on multiple monitors at one time, which is highly advantageous in presentation or educational meetings; (7)

the system improves the ergonomics greatly, which frees the dentists from prolonged physical strain. The dentist is freer in his movements and needs not bend over with the weight of loupes and headlights burdening him, causing him pain; (8) the system is highly mobile. Because the system has no eyepiece, the dentist can move the camera head virtually any angle or position that he/she wishes, even at the side of the patient' s mouth, which is impossible with the traditional microscope; (9) the learning curve for the system is very short. The dentist does not have to become versed in microscopic techniques. The digital display of the image on a monitor and the clear and simple push button operation of the system make it simple for anyone to use; (10) the depth of field is unequalled in any other scope. The depth of field is absolutely necessary in dental procedures because the dentist needs an accurate representation of the dimensionality of the mouth in order to work accurately. Without depth of field the mouth appears to be a flat surface with no dimension. Analog scopes, that have a video camera attached, have no/or limited depth of field, making it difficult to perform almost any procedure that requires the dentist to discern the three—dimensional environment of the mouth; (11) the system is a digital microscope; (12) the system offers a digital microscope with an all-in-one package including image processing and management software, computer with hard drive for image and data storage, 17" LCD monitor, control panels, built-in motorized video camera; (13) the view of the camera can be adjusted without looking into an eyepiece, from a comfortable sitting position all viewing adjustments can be made with the click of a button; and

(14) the field of view remains large even during high magnification, not losing sight of the larger picture.

Although the present invention is briefly summarized, the fuller understanding of the invention can be obtained by the following drawings, detailed description and appended claims.

The beam splitter 18 is disposed in the optical axis 91 of the microscope with forty five (45)—angles to the optical axis 91, and reflects the light from the mirror or prism 15 to the object 90 and allows the light from the object 90 to the lens assembly 14 of the microscope 10 to pass.

The digital surgical scope 10 has an adjustable magnification up to one hundred twenty (120) times including optical and digital zoom. The method SlOOO further includes steps of creating a database of information on a new patient S1018 and searching information or an exam history on a predetermined old patient from the database S1016 as in Fig. 2.

Alternatively, a dental microscopic procedure, using a digital surgical scope 100, includes steps for a) creating an entry in the database for a new patient (S1012) ; b) selecting a predetermined patient and retrieving the related information from the database (S1016) ; c) displaying the retrieved information (S1014) ; d) creating a new exam for the patient (S1018) ; e) opening the exam history and selecting an exam of the patient (S1024) ; f) capturing images (S1022) ; g) enhancing images (S1026) ; h) browsing a history of the patient (S1028) ; and i) selecting and performing functions on the images (S1032) . The function includes deleting, exporting, importing, multi- viewing, printing, and managing the images with the database as shown in Fig. 2.

The step (SlIOO) of capturing images includes steps of cl) adjusting live image quality by adjusting the camera controls, white balance, RGB color gamma value, viewing area, zoom in, zoom out, and full screen, wherein the camera control includes gain, offset, and exposure (S1102) ; c2) viewing the adjusted live image (S1104) ; c3) capturing a snapshot image and a video clip (S1106) ; c4) controlling the capturing with a foot pedal or a button (SlIlO) ; c5) replaying the captured image or video (S1120) ; and cβ) viewing details of the image or video (S1122) by selecting functions of deleting, saving, and refreshing (S1124) as shown in Fig. 3.

The step of enhancing images (S1200) includes steps of el) adjusting the image quality by controlling brightness, contrast, edge enhancement, and histogram contrast (S1202) ; e2) analyzing the images to manipulate the image to rotate, zoom in, zoom out, pan, magnify, and measure geometrical dimension, and the geometrical dimension includes angles, lengths, distances between two points (S1208) ; and e3) annotating the image for adding text and geometrical objects, and the geometrical objects includes lines and shapes (S1212) .

One of the most remarkable claims is the control functions: zoom-in/out, focus, brightness, recording live streaming video, taking snapshots of digital images, and viewing the recorded video at any time. These functions can be easily performed by using a foot pedal or hand control .

Dentists can adjust zoom, focus, and brightness as well as record live streaming video and take snapshots of the video using the foot pedals. These foot pedals reduce the dentist's need to touch the scope during a procedure or surgery and eliminate having to put down the dental instruments to make adjustments, thus reducing the worry for possible contamination. Also, dentists can make these adjustments without another person's assistance. The Digital Surgical Scope has multiple control options for zoom, focus and light adjustment with just a touch of a button.

Front Panel Buttons

The front panel has a power button for the computer and a button to turn the light on and off. To the left are 6 blue buttons that give you control options to zoom in/out, a button to adjust focus, and a button to adjust brightness. The LCD screen allows you to view your selections . Dual Arm Controls

On the outside edge of the articulating arm is a button that controls the entire camera. Simply press this button to move the camera up or down, effortlessly. The other buttons give you control options to zoom in or out, a button to adjust focus, and a button to adjust brightness.

On the camera handles are Actuator Buttons, which controls the movement of the articulating arm. Press and hold both buttons simultaneously, then lightly push or pull the arm to position the camera in any direction; up, down, sideways, or backwards with ease and fluidity. Releasing the actuator buttons will lock the articulating arm into place.

Articulating Arm

The Articulating Arm has many advantages over other microscopes. The first advantage is the motorized arm. From a permanent base, the articulating arm locks into position giving it strong stability. This means the camera will always be stable when directed at the area of interest. Even with a reasonable amount of outer force, the articulating arm will not budge.

Another advantage is that when the camera is not in use, you can move it out of the way until you need it again and it will restore back to its original position. This means that you won't have to refocus on the area of interest when the camera returns to the position.

Another advantage is that when you release the actuator buttons, the articulating arm will lift up automatically instead of forcing the arm into another position. Foot Pedal

The Digital Surgical Scope gives you the option of hands-free operation with two different foot pedals that allow you to make adjustments while keeping your hands free during procedures. There are two Foot Pedals: The Adjustment Foot Pedal (focus/zoom/iris) and the Record and Capture Foot Pedal (replay/ ^' capture/'record.)

The Adjustment Foot Pedal has the same functions as the camera handle controls and the front panel buttons on the Membrane Switch. It is used to control zooming in/out and to adjust focus and brightness.

The Record and Capture Foot Pedal allows you take a snapshot, start or stop a live streaming video recording, or replay a video recording.

While the invention has been shown and described with reference to different embodiments thereof, it will be appreciated by those skilled in the art that variations in form, detail, compositions and operation may be made without departing from the spirit and scope of the invention as defined by the accompanying claims.
