Description

Improved structure of endoscope

The present invention relates to an endoscope, and in particular, to an improved structure of the endoscope that integrates multiple wavelength light sources and digital image processing, has good heat dissipation, and simplifies the system architecture.

Endoscopy is a diagnostic tool that has been used by the medical community for decades. It is used to peer into the inside of the body, such as the stomach, large intestine, ovaries or uterus... and other diseases. Until recent years, with the development of electronic technology, endoscopic surgery combined with sophisticated surgical instruments has led to the development of endoscopic surgical therapy, also known as minimally invasive surgery (MIS).

In addition, the term "minimally invasive surgery" was coined by British physician John EA Wickham in 1984 and published in the British Medical Journal in 1987. Early minimally invasive surgery specifically referred to laparoscopic surgery, and the original laparoscopic surgery could only be replaced by minimally invasive surgery. It was not until later, when minimally invasive surgery technology became more popular, that it was gradually extended to operations on other parts of the body; if the endoscope is applied to the chest, it is called "thoracoscopy", and if it is applied to the abdomen, it is called "laparoscopy". Commonly used in orthopedics is called "arthroscopy". These endoscopes are further connected to an external display imaging system, which can clearly display the patient's internal condition on the screen, and then use special surgical instruments to perform surgical treatment on the patient.

Generally speaking, a typical endoscope system usually includes an endoscope, a system platform, and an optical fiber cable. The system platform generally includes a light source device for providing a light source, and a light source device for displaying the images captured by the endoscope. Image display devices, processors for processing image signals, etc. The system machine is connected to the endoscope through an optical fiber cable. The light generated by the light source device is transmitted to the endoscope through the optical fiber cable. At the same time, the image obtained by the endoscope is transmitted back to the processor through the optical fiber cable. However, traditional endoscopes Telescope surgical systems often have the following shortcomings and need to be further improved:

(1) A special light-guiding multi-mirror structure is provided in the conventional endoscope to transmit the light image at the objective end of the endoscope to an image eyepiece located at the rear end of the endoscope, and the illumination source is passed through a special The light guide is transmitted to the objective lens end structure, which is not only complex in structure but also expensive.

(2) Traditional endoscopes use charge-coupled devices (CCD for short) as image sensors, so an additional analog-to-digital converter (A/D converter for short) is required. To convert the analog signal output by the CCD into a digital signal, the analog-to-digital converter will not only cause image distortion but also occupy additional volume.

(3) Today’s medical institutions all follow standard disinfection, sterilization and other procedures before reusing them. However, the aforementioned standard disinfection and sterilization procedures cannot achieve complete sterilization of endoscope components. That is to say, even if the used endoscope components undergo rigorous multi-channel standard disinfection and sterilization procedures, it is impossible to ensure that the endoscope components are completely sterilized. Once there are still bacteria or viruses remaining in the endoscope components after disinfection and sterilization procedures, the subjects who use the endoscope in the future are prone to risks of bacterial infection, viral infection, etc. due to the transfer of bacteria or viruses. Furthermore, the disinfection and sterilization procedures only deal with the endoscope structure. However, the optical fiber cables connecting the system machine and the endoscope cannot be sterilized, resulting in the endoscope connection after sterilization. After fiber optic cables, there are still issues with bacterial infections.

(4) Although some manufacturers have tried to develop products that install image sensors at the front end of endoscopes, they have been unable to solve the problem of how to squeeze the illumination light source, image sensor, and image sensing into the narrow front end of the endoscope at the same time. The high heat generated during the operation of the device will cause the temperature of the front end of the endoscope to rise to above 42°C in a short period of time, thereby scalding human tissue, and it does not comply with the safety regulations of electrical medical equipment.

(5) In the technical field of existing medical equipment, in order to solve the aforementioned problems of bacterial infection, viral infection, etc., there is a technical concept of disposable equipment. This means that medical equipment such as syringes cannot be reused when placed in the patient's body, such as syringes, etc. . However, in the field of endoscopes and other endoscope devices, due to factors such as the precision, complexity, and reliability of the overall mechanism of the endoscope device, and the expensive equipment costs, existing endoscopes and other endoscopes are maintained Due to the reuse method, problems such as bacterial infection and viral infection caused by repeated use of endoscope components during the use of endoscopes and other endoscope devices cannot be overcome.

Endoscopic surgery, also known as minimally invasive surgery, appeared in the 1980s and is a safe and effective surgical method. As the benefits of endoscopic surgery include: ● Small incision or few incisions ● Reduce pain ● Low risk of infection ● Short hospital stay ● Fast recovery time ● Reduce scars ● Reduce blood loss Therefore, endoscopic surgery techniques and various instruments were developed and gradually expanded to be applicable to the treatment of a variety of most surgical diseases.

Surgical instruments are high-risk instruments that come into contact with blood and body fluids and even various germs and microorganisms. Sterilization before reuse is very important. In particular, the cleaning steps of endoscopes are quite cumbersome, including pre-processing, leak detection, cleaning and disinfection. The process from drying, storage to use involves multiple steps. If each step is not accurate, cross-infection may easily occur.

In particular, the instruments used in endoscopic surgery are complex and small in structure, which are not only difficult to clean and sterilize, but also easily increase the risk of infection. They are also easily damaged during handling steps. Therefore, there is a strong demand and trend for disposable instruments for endoscopic surgery.

The present invention uses the miniaturization of smartphone camera digital components and the illumination of LEDs of various wavelengths and intensity to form a new structure of surgical endoscopes, which can achieve the functionality, safety and low cost that disposable instruments must meet. Price conditions.

Surgical endoscopes mainly consist of an imaging part and an illumination part.

So far, the image part, as shown in Figure 1, is transmitted from the objective lens to the eyepiece through a combination of multiple lenses. Because there are many lens groups, the fixation must be precise otherwise it will cause dispersion and image distortion. It is difficult to make, and the resolution requires a very thin optical fiber to transmit the image to the host for image processing. Therefore, it is expensive and only suitable for repeated use. And although the endoscope can be sterilized, the fiber optic cable can only be disinfected by wiping, so the risk of infection still exists.

As shown in Figure 2, the image processing part of the present invention uses a near-focus lens group like that of a smartphone to be fixed on the objective lens end and processed directly by the COM image sensor and digital IC, and then transmitted to the image processing module in the host through wires. , save and edit the image and then send it to the monitor. These new lens sets, image sensors, digital ICs and wires are all inexpensive, and are completely sterilized from the host interface to the endoscope, which can minimize the risk of infection.

The current method of illumination is as shown in Figure 3. A 300W discharge electrode is placed at the focus of a parabolic surface, the necessary spectrum is taken out through a filter, and then the illumination light is transmitted to the illumination interface on the side of the endoscope through the condenser lens.

As shown in Figure 4, the present invention uses LEDs with various spectrums and products that can produce 100Lux at 1W as lighting sources. Usually, endoscopic illumination is 1000~2000Lux, so only 10~20W LEDs are needed. Figure 3 is To produce a wide spectrum and strong light, a large 300W power is used. As for the position of the LED at the objective lens end, it will generate heat, which is harmful to the organs and the area is limited. In addition, a light-concentrating light-conducting material placed at the original eyepiece at the upper end of the endoscope is used to transmit the illumination light to the objective lens end.

As shown in Figure 5, the LED COB can also use LEDs of different spectrums as two or more different light sources at the same time. Because LEDs generate heat, they must be cooled with cold air to ensure the stability of the light source. The present invention does not require a 300W discharge method, not only saves power, but also can switch between two or more light sources of different spectrums using a button, and the lighting intensity can be adjusted by adjusting the voltage of the LED to suit the luminosity. A disposable new sterilized catheter is used from the host computer to the endoscope, which is a disposable disposable catheter that is discarded after use to reduce the risk of infection.
