It can be seen that infrared imaging is an important complement to other morphological diagnostic methods such as B-ultrasound, CT, and MR.

Hysteroscopy is the core device for gynecological examination and gynecological surgery. The hysteroscope is connected with the camera host, monitor and cold light source. With a variety of surgical instruments, the doctor can go deep into the uterine cavity and treat the intrauterine cavity. Lesion.

There is currently no endoscope system that uses an infrared thermal scanning probe in combination with a hysteroscope. Therefore, it is extremely urgent to design a hysteroscopic system with infrared thermal scanning function that combines infrared thermal scanning technology with hysteroscopy. Summary of the invention

The object of the present invention is to overcome the deficiencies of the prior art and to provide a hysteroscopic system with infrared thermal scanning function, which introduces infrared thermal scanning technology into a hysteroscopic system, through an infrared thermal scanning probe to the palace The cavity wall tissue is scanned stereoscopically, and the data obtained by multi-plane continuous cross-cutting scanning is transmitted to the host of the infrared thermal scanning system for image processing, and the stereoscopic blood vessel static image of the uterine cavity wall is clearly displayed, and the doctor is provided with an infrared heat of the uterine cavity wall.

The infrared system of the present invention has a working principle: the wall of the uterine cavity is covered with abundant blood vessels, and the temperature of the arterial blood is high. The venous blood temperature is low, there is some kind of heat exchange system, both of which radiate different wavelengths of infrared rays. The temperature of the uterine wall tissue not only receives the blood flow in the blood vessels, but also is affected by its own metabolism. Therefore, the temperature of the uterine wall tissue will be different due to the difference of the blood vessels rich or not, and the wavelength of the externally radiated infrared rays. The lesions of the inflammatory tumors between the uterine walls will be due to their The metabolism is active and its temperature is significantly higher than normal. Studies have shown that blood components (serum, plasma, hemoglobin, albumin, red blood cells, lymphocytes, platelets) have the lowest absorption of infrared light in the spectrum, meaning that in addition to external radiation, the blood also has infrared rays to the surrounding tissue. The absorption effect is very small. The accuracy of the infrared system is less than or equal to 0.05 degrees, and the spatial resolution is at least 0.8mrad. The infrared thermal scanning probe scans at a close distance in the uterine cavity to obtain a fine and precise infrared image.

At the same time, the signal input to the host also has a synchronization signal, a reference black body signal, and the like. The data obtained by the multi-plane continuous cross-cut scan is transmitted to the host of the infrared thermal scanning system for image processing, and output to the infrared system monitor to clearly display the stereoscopic image of the uterine wall stereoscopic blood vessel. The doctor can analyze the image and find the intrauterine wall. Abnormal vascular abnormalities, sparse vascular abnormalities, or abnormalities such as vascular loss areas provide doctors with immediate diagnosis.
