On May 20th, good news came again from the First Affiliated Hospital of Xi'an Jiaotong University. After the world's first 30W blue laser surgical equipment was successfully developed and put into clinical use, Professor He Dalin's team and Dr. Mu Liyue's team from Lanji Medical worked together to achieve excellent results. They successfully developed a high-power 200W blue laser surgical equipment and officially obtained the Class III medical device registration certificate issued by the National Medical Products Administration. This is also the most efficient laser energy platform equipment in the world for vaporization cutting, fully reflecting the various advantages of laser surgery, while avoiding the disadvantage of low vaporization cutting efficiency of other laser energy platforms. The successful launch of the equipment is a significant achievement in the establishment of the National Medical Center of the hospital, fully demonstrating the huge achievements of medical industry intersection, medical enterprise cooperation, and achievement transformation. It is a concrete manifestation of promoting medical technology innovation and leading the new trend of high-quality development of public hospitals.

The 30W blue laser surgical system is a laser treatment equipment designed for the treatment of human luminal mucosal epithelial lesions. Combining the characteristics of blue laser in biomedical and biophysics, as well as the treatment principles and requirements of human luminal mucosal epithelial lesions, it achieves fast vaporization speed, high cutting accuracy, and good hemostatic effect. Based on the research concept of 30W blue laser, Professor He Dalin's team found that under the same power and unit time, the 200W blue laser surgical equipment has a significant effect on treating prostate hyperplasia. This device has the highest tissue vaporization efficiency, with an appropriate thickness of the coagulation layer, which can quickly vaporize the prostate tissue blocked in the urethra. At the same time, it has the characteristics of minimal damage to the periphery of the surgical area, less intraoperative bleeding, fast postoperative recovery, and low noise, greatly shortening the surgical time for doctors and improving patient satisfaction.

On May 7th, the urology department of Xi'an Jiaotong University First Affiliated Hospital successfully performed two surgeries using the world's first 200W blue laser surgical equipment. Patients A and B were diagnosed with benign prostatic hyperplasia by ultrasound due to difficulty urinating and were admitted to the hospital. After communicating with the patient's family, they were given transurethral prostate vaporization surgery. During the surgery, a domestically produced blue laser surgical system was used for prostate vaporization, which had high vaporization efficiency, low noise, good field of vision, and almost no bleeding during the operation, Non carbonized tissue (beneficial for wound healing). On the second day after surgery, the patient's urinary tract drainage was clear, the condition was stable, and he felt good. He had eaten and received water. Currently, the patient has recovered and been discharged from the hospital.

According to the requirements of the National Medical Products Administration for Class III medical device certification application and registration, this device was mainly studied by Professor Liang Chaochao from the First Affiliated Hospital of Anhui Medical University, Professor Li Zhijun from the First Affiliated Hospital of Henan University of Science and Technology, and Professor Li Lei from the First Affiliated Hospital of Xi'an Jiaotong University. According to the relevant requirements, strict clinical trials were conducted, fully demonstrating the efficient vaporization speed of the 200W blue laser surgical equipment Stable security performance. At present, the surgical system has been clinically applied in the First Affiliated Hospital of Xi'an Jiaotong University, the First Affiliated Hospital of Anhui Medical University, Xianyang Central Hospital, and Xi'an High tech Hospital.

Associate Professor Zou Zhihui from the First Affiliated Hospital of Anhui Medical University, who participated in the clinical trial, gave feedback that "200W blue laser vaporization of the prostate is currently the fastest energy platform in the world. This surgical system has the conditions for performing daytime BPH (benign prostatic hyperplasia) surgery, making it a high-risk and complex patient with benign prostatic hyperplasia."

At the same time, breaking the boundaries between disciplines, the 30W blue laser surgical equipment was applied to the field of obstetrics and gynecology surgery, and successfully performed endometrial polyp surgery in the First Affiliated Hospital, Second Affiliated Hospital, and Provincial People's Hospital of Xi'an Jiaotong University. Afterwards, the 30W blue laser surgical system will also be applied in the treatment of diseases such as ear, nose, throat, and digestive tract.

The research and development of the equipment reflects the interdisciplinary development direction of hospital medical engineering and collaborative innovation, while the cooperation between hospitals and enterprises reflects the problem of technology achievement transformation. Professor He Dalin's team fully demonstrates the scientific spirit of Chinese medicine. On the path of future medical technology innovation in China, Xi'an Jiaotong University First Affiliated Hospital will continue to deeply integrate medical and industrial fields, creating a world leading research and development and manufacturing highland in the field of laser medical equipment.
