Description

Technical Field

[0001] The present invention belongs to the technical field of thoracic cavity illumination, and particularly relates to an endothoracic thoracoscope imaging device. Background Art

[0002] The objective lens system at the front end of the thoracoscope collects the light in the thoracic cavity and transmits the light to the observation eyepiece or the connected imaging system through an optical transmission / imaging conversion system. This process utilizes optical elements such as lenses and optical fibers to image the organs, tissues, blood vessels and other structures in the thoracic cavity, enabling doctors to observe details such as the shape, color, and structure inside the thoracic cavity. Modern thoracoscopes mostly adopt electronic imaging technology, and high-resolution charge-coupled devices or complementary metal oxide semiconductor image sensors are installed inside their lenses. These sensors convert the optical image in the thoracic cavity into an electrical signal, which is then digitally processed and optimized by an image processing circuit and finally transmitted to a display to be shown as a clear image. Traditional thoracoscopic surgeries usually require multiple incisions on the patient's body surface to insert the thoracoscope and other surgical instruments. Most existing thoracoscope imaging devices are fixed outside the patient through a complex external support structure or in combination with other instruments. This not only occupies a large amount of surgical operation space, but also increases the complexity of the surgery, easily causing additional trauma to the patient, and also affecting the surgical efficiency and safety to a certain extent. For this reason, we have proposed an endothoracic thoracoscope imaging device. Summary of the Invention

[0003] The purpose of the present invention is to provide an endothoracic thoracoscope imaging device, which fixes the imaging device inside the chest wall by magnetic attraction or attachment. The imaging system includes an imaging unit, a fixing device, a power supply unit, and a signal transmission unit. The imaging unit is fixed on the chest wall and can capture high-definition images inside the thoracic cavity. The fixing device adopts magnetic attraction or attachment technology to ensure the stability and safety of the imaging device in the thoracic cavity. The power supply unit can be an internal battery or an external power supply connected through a signal transmission line to provide continuous and stable power supply for the imaging device. The advantages of the present invention are that by integrating the imaging system, the number and complexity of instruments during the surgery are significantly reduced, thereby increasing the operation space for surgical instruments, improving the surgical efficiency and safety. In addition, this design reduces the invasiveness of traditional thoracoscopic surgeries, improves patient comfort, and is suitable for real-time imaging observation in thoracic surgery.
