DETAILED DESCRIPTION OF THE INVENTION

[0048] In this detailed description, desired modes/structuring of the instrument for early diagnosis of larynx cancer (1) are given for clarity without any limitations.

[0049] This invention is concerned with an indirect laryngoscope instrument (1) for early diagnosis of larynx cancer, to be used in the field of medicine for imaging the larynx.

[0050] FIG. 1 depicts a three-dimensional view of the instrument for early diagnosis of larynx cancer (1). This invention, as seen in FIG. 3 in its indirect laryngoscope section (1.1), involves a camera (1.1.2) at the center of the semi-transparent mirror (1.1.1). During the examination, the doctor is able to image the larynx tissue using the camera (1.1.2) and transmit using the RF transmitter (1.3.1) to the external monitor. The larynx images of the patients that are acquired with the camera (1.1.2), can be gathered in a portal. Thus, the images that are collected at the portal are shared with specialists for correct diagnosis of the symptoms. For example, tissue images that are gathered during a dental examination are also transferred to an otorhinolaryngologist, thus enabling early diagnosis and treatment of the possible larynx cancer, preventing metasthasis.

[0051] The invention includes LED lights (1.1.3) at the periphery of the semi-transparent mirror (1.1.1) in the indirect laryngoscope section (1.1). LED's (1.1.3) are stroboscopic light sources. Main advantages of the instrument for early diagnosis of larynx cancer (1) is the ability of the long-lasting LED lights to act as a continuous as well as stroboscopic light source, smart and low decibel, having a pure white illumination at 6300 K. The instrument for early diagnosis of larynx cancer (1) is locked to the fundamental frequency of the sound that is detected with the microphone (1.1.4) and calculated with the known techniques. The instrument for early diagnosis of larynx cancer (1) deduces the fundamental frequency as follows: A circuit (1.2.3) is located in the handle section (1.2). This circuit (1.2.3) could either be an electronic circuit or a PLL (Phase-locked-loop). The circuit (1.2.3) measures the fundamental frequency through the software embedded inside the microcontroller or using PLL. LED lights (1.1.3) are illuminated with the measured frequency. Owing to the stroboscopic nature of the LED's (1.1.3) the doctor observes the vocal cords as stationary during larynx examination.

[0052] The invention comprises a microphone (1.1.4) at the indirect laryngoscope section (1.1). In an alternative arrangement, the microphone (1.1.4) is located in the handle section (1.2). The physician carefully inserts the instrument for early diagnosis of larynx cancer (1) into patient's mouth. The larynx is first observed while the patient is at rest. Then, the vocal cords are examined while the patient is asked to make A and Hi sounds, during which the microphone (1.1.4) automatically deduces the fundamental frequency of the sounds and the operation frequency of the LED (1.1.3) is adjusted accordingly. The number of cycles that the glottis (inter-vocal cord tissue) makes is denoted as the fundamental (basal) frequency. The fundamental frequency during speech is typically in the 100-150 Hz for men and 150-250 Hz for women. The instrument for early diagnosis of larynx cancer (1) first determines the fundamental frequency of sound with techniques known by those skilled in the art. Then, the instrument adjusts illumination frequency of LEDs (1.1.3) according to the determined frequency again with techniques known by those skilled in the art.

[0053] The invention includes a frequency adjustment knob (1.2.1) at the handle section (1.2). The frequency adjustment knob (1.2.1), is used for tuning the LED (1.1.3) frequency in accordance with the fundamental frequency of the voice that is captured through the microphone (1.1.4). With the frequency adjustment knob (1.2.1), the fundamental frequency can be adjusted as 10, . . . 2, 1, 0, +1 or +2 . . . , +10. For example, if the frequency adjustment knob (1.2.1) is set to 0, the LED frequencies are tuned to the fundamental frequency of the sound, captured through the microphone (1.1.4). On the other hand, if the frequency adjustment knob (1.2.1) is adjusted to +1, the instrument for early diagnosis of larynx cancer (1) adjusts its frequency to 1 Hz above that of the fundamental frequency that is captured via the microphone (1.1.4). When the frequency adjustment knob (1.2.1) is set to 0, the physician observes the vocal cords as stationary. When adjusted to 1, 2, +1 or +2, the doctor observes the vocal cords to be moving very slowly. The doctor is free to set the frequency adjustment knob (1.2.1) to a fundamental frequency with which s/he is comfortable to work with to examine vocal cord movement. For example, if the patients fundamental frequency is observed to be 300 Hz, when asked to make A or Hi sound, and if the frequency adjustment knob (1.2.1) is set to 0, the device for early diagnosis of larynx cancer (1) automatically sets its frequency to 300 Hz. But, if the frequency adjustment knob (1.2.1) is set to +1, the instrument for early diagnosis of larynx cancer automatically sets its frequency to 301 Hz. When the measured frequency of the patient is 300 Hz and the frequency adjustment knob (1.2.1) is set to 0, the physician observes the vocal cords as stationary. If the measured frequency of the patient is 300 Hz and the frequency adjustment knob (1.2.1) is set to +1, the instrument for early diagnosis of larynx cancer (1) operates at 301 Hz and the doctor observes the vocal cords as moving.

[0054] The invention involves an RF transmitter (1.3.1) in its power section (1.3). With the RF transmitter (1.3.1) the images acquired with the camera (1.1.2) can be transferred to an external monitor. The larynx images that are acquired with the camera (1.1.2) can be gathered in a portal. This way, as mentioned earlier, the images that are gathered in the portal can be shared with larynx experts for precise diagnosis.

[0055] The instrument for early diagnosis of larynx cancer (1), consists of an indirect laryngoscope section (1.1), the handle (1.2) and the power (1.3) sections. These units can be integrated, or alternatively combined in a modular fashion as shown in FIG. 4. That is, while the indirect laryngoscope (1.1) and the handle (1.2 sections) are integrated, the power section (1.3) is modular and can be separated. The benefit is to be able to isolate the power section (1.3) from the indirect laryngoscope (1.1) and handle (1.3) for charging also to be able to sterilize the indirect laryngoscope (1.1) and the handle (1.2) sections, without the power (1.3) section. The physician's office can keep a single power unit (1.3), while having 10 or more of the indirect laryngoscope (1.1) and handle (1.2) units. After the examination, the physician separates the integrated indirect laryngoscope (1.1) and handle (1.2) section from the power section (1.3) for sterilization, while connecting a sterilized pair of integrated indirect laryngoscope (1.1) and handle (1.2) sections to the power unit (1.3) that he has just used, for the next patient.

[0056] In another aspect, device modularity embodiment involves, rechargeable batteries (1.3.4) that are located in between the connection point of the power section (1.3) and the handle section (1.2). After being separated from the entire mechanism, the rechargeable batteries (1.3.4) are charged and re-inserted between the power (1.3) and handle (1.2) sections, for the continuity of electronic operation. In another embodiment, the instrument for early diagnosis of larynx cancer (1) is composed of an integrated indirect laryngoscope (1.1), the handle (1.2) and the power sections (1.3). in this alternative form, the instrument for early diagnosis of larynx cancer (1) is sterilized as a whole. The power input (1.3.2) that is dedicated for charging the device (1.3.2) stays outside the sterilization boundary to prevent oxidation. The power input (1.3.2) is located at the top of the power unit (1.3)

[0057] The interconnection between the power section (1.3) and the LEDs (1.1.3), the camera (1.1.2), the microphone (1.1.4) and the frequency adjustment knob (1.2.1) located in the indirect laryngoscope section (1.1) are maintained via electronic cables (1.2.2).

[0058] The instrument for early diagnosis of larynx cancer (1) can be powered up through the power section (1.3), by rechargeable batteries (1.3.4), through being charged using the power input (1.3.2) or also via a power cable (1.3.3) that can be externally connected.

[0059] The application of the instrument for early diagnosis of larynx cancer (1) is as follows:

[0060] The physician observes the larynx of the patient by inserting the instrument for the early diagnosis of larynx cancer (1) inside the patient's mouth, through the illuminating the area with the LED lights (1.1.1). Afterwards, the vocal cords are examined through asking the patient to make A and Hi sound. The microphone (1.1.4) acquires the sound and deduces the fundamental frequency, with which the illumination frequency of the LEDs (1.1.3) of the instrument for early diagnosis of larynx cancer (1) is adjusted using known techniques (Via electronic circuitry or PLL). The physician able to adjust the LED illumination frequency adjustment knob of the instrument for early diagnosis of larynx cancer (1) to one of 10, . . . 2, 1, 0, +1 or +2 . . . , +10 settings. The physician is able to understand and diagnose the larynx through either observing the vocal cords at matched LED illumination frequency and voice fundamental frequency, or at slightly unmatched frequencies to observe the vibration of the vocal cords in slow motion.
