The near-infrared light-gold nanorod treatment system of Qilu Hospital has been busy for 9 days and finally performed cancer cell killing surgery on 17 patients.

If it is in the early stage, the tumor is not big, then you can undergo a surgery in twenty or thirty minutes.

If you are a patient with complex conditions similar to Wang Jinbang, you need to do a slow and meticulous work, and a single operation may not be completed in two or three hours.

Wang Jinbang, the first to undergo surgery, has recovered for nine days, although the large intestine has not been able to defecate for the time being.

However, according to Chang Zhiwen's follow-up observation, Wang Jinbang's large intestine lesions have begun to recover bit by bit. It is estimated that after raising it for one or two months, he can restore his normal life.

The other 16 patients recovered in line with expectations, and even the most difficult pancreatic cancer to treat was killed very thoroughly.

Near-infrared light does not have any serious harm to normal human cells. After all, the sunlight we emit daily contains a lot of infrared, visible light, ultraviolet light, etc.

Generally speaking, in each frequency band of light wave, the longer the wavelength, the stronger the penetration effect on the human body. According to the wavelength, it is arranged from long to short, namely: mid-infrared light, near-infrared light, visible light, near-ultraviolet light, medium-ultraviolet light, deep ultraviolet light, and X-ray.

Compared with the scary ultraviolet light, X-rays and near-infrared light are even safer than visible light, after all, the penetration of wavelengths is there.

Near-infrared light and human cells (including cancer cells) are difficult to form a "resonance effect" and will directly penetrate the human body.

To describe it in one sentence, it means coming quietly and slipping away quietly without leaving a trace of energy.

Near-infrared light ignores human cells but has a special liking for metal crystals. It is easy to encounter nano-level metal crystals, causing a "resonance effect".

In summer, if you touch some metal products exposed to the sun, it will feel very hot, because metal is a good conductor of heat.

Silver, copper, gold and aluminum rank among the best in thermal conductivity in metals. Excluding copper and aluminum that may be harmful, gold and silver are most suitable as "light wave resonance" targets for gold-infrared light.

In a series of studies, the thermal conductivity and light wave resonance effects of one of the gold nanorods stand out from a number of materials and meet the safety window of near-infrared light.

This is how to achieve the perfect combination of near-infrared light and gold nanorods, and the technology to jointly annihilate cancer cells.

According to the current near-infrared development power and light-heat killing power, the development power, even if it is continuously irradiated for four or five hours, it will not cause any serious harm. It may be smaller than the amount of radiation we emit from the sun for more than ten minutes.

The light-heat killing power will be relatively high, but this power will usually not exceed 2 to 3 minutes for the same part, and the optical radiation dose is only less than one-seven percent of the CT. Perhaps the optical radiation dose we look at mobile phones is higher than this dose.

This is the resonance effect of near-infrared light, which only transmits energy to the gold nanorod, and other energy will directly penetrate the human body with infrared light.

Compared with the cruel X-knife, gamma sword, wave shooting sword, or the neutron sword, proton sword, and meson sword that have emerged in recent years.

The infrared light heater has better treatment effect, and the side effects are very low, so the price does not need to be too high.

Under medical insurance reimbursement, the treatment cost of patients in the early stage will not exceed 5,000 yuan, the intermediate stage will be about 10,000 to 20,000 yuan, and the late stage will be about 30,000 to 80,000 yuan.

The cost-effectiveness basically beats the second-generation radiotherapy equipment and the third-generation radiotherapy equipment. It is definitely a huge benefit for the promotion of infrared light heaters in China, where the population is large and medical resources are relatively tight.

These days, many media at home and abroad have been watching Qilu Hospital, just waiting for the clinical test of infrared light heater equipment.

Wang Xiaobing, who was sent to interview, gave an exclusive interview to Chang Zhiwen outside the sanitary ward.

Facing the camera, Wang Xiaobing introduced: "My viewers in front of the TV, Wang Xiaobing, a reporter from our national TV station, is now reporting to you the world's first infrared light heat-knife tumor treatment system..."

The camera turned and cut to Chang Zhiwen.

"Hello, Dr. Chang, what is the current situation of the first batch of patients tested?"

Chang Zhiwen replied with a smile: "At present, the bodies of the 17 patients have all passed the dangerous period. Among them, four of the early patients can be discharged after staying in the hospital for about ten days. The advanced patients need to be observed for about one month."

Next, Wang Xiaobing interviewed several patients, but did not commit fraud on the spot. Although the patients' expressions were not very good, their energy gradually recovered.

This is the advantage of the photothermal knife, which is ultra-low radiation and ultra-low damage, and the patient does not experience side effects such as hair loss, osteonecrosis, insomnia and nausea.

The killed cancer cells will also become nutrients for normal cells and are gradually decomposed or excreted from the body.

After interviewing several patients, the picture changed and Wang Xiaobing and Chang Zhiwen appeared in the operating room of Guangren.

"Doctor Chang, is this device an infrared light heater device?"

"Yes." Chang Zhiwen nodded.

Wang Xiaobing asked many questions that people are concerned about: "What is the overall price of this equipment?"

"Currently, Shennong Group offers a set of 8.5 million yuan. Compared with the heavy proton knife equipment with a cost of more than one billion yuan, the cost performance is very high."

Wang Xiaobing nodded and continued to ask: "Doctor Chang, I believe many patients are very concerned about one issue, that is, the treatment cost of light heat knife therapy, which is the approximate range?"

"The depreciation fee of the equipment itself is not high, but the solar thermal knife requires special gold contrast agent, the price is 2,000 yuan per unit. Usually, patients use 1 to 4 units in the early stage, patients use 5 to 8 units in the middle stage, and patients may need 9 to 15 units in the late stage."

Chang Zhiwen did some calculations for the patient. It seems that the minimum price is tens of thousands, but considering the reimbursement ratio of medical insurance, the price is already acceptable to ordinary people.

If it is really difficult, you can also apply for charitable funds, local financial assistance, social donations, etc.

Compared with the radiotherapy that was hundreds of thousands of dollars in the past, it was costly and painful, and there were many patients who could not last for five years after treatment.

Nowadays, the maximum price of the hot knife is only 70,000 to 80,000, and usually 10,000 or 20,000 can be handled. Most patients are willing to accept this price.

What's more, the Ministry of Health is already making plans, intending to include tumor treatment in special subsidies, increase the overall reimbursement ratio to about 80%, and set up a special subsidy for poor households.
