Holographic image showing blood vessels
Recently, the Wuhan Union Hospital Orthopaedic Hospital successfully implemented the world's first mixed reality (MR)-guided hip fracture surgery for a patient. The real-time shared holographic image allows doctors to perform surgery such as “transparent peopleâ€. The patient was a 15-year-old girl who suffered a left hip fracture due to a fall and was diagnosed with a left femoral neck fracture after admission. If not handled properly, it is prone to sequelae such as nonunion of the fracture and avascular necrosis of the femoral head.
To this end, the Concord Hospital Orthopaedic Hospital Ye Zhewei Chief Physician and Associate Professor Wu Xinghuo's surgical team decided to adopt the latest mixed reality technology - a holographic image of the female femoral neck fracture.
On June 25, before the operation, the patient wore VR glasses, and under the doctor's explanation, 360-degree view of the 3D digital “replica†of his fracture site, and an intuitive understanding of his fracture specific situation and surgical plan.
On the 26th, the surgeon and assistant doctor used the holographic image information to overlap the patient's virtual 3D digital model with the patient's lesion. The doctor has a new high-dimensional "perspective" surgical area tool. Hollow Man.
Ye Zhewei explained that the mixed reality technology has brought great convenience to the surgery. Previously, the doctor could not see the 3D display of the human tissue during the operation, and the 3D display was corresponding to the actual anatomical part of the patient. The hybrid reality technology can grasp the internal information of the patient under the condition that the surgeon does not fully open, and superimpose it on the virtual physical space to realize the precise surgical treatment plan.
What is even more amazing is that the holographic image model is moved to the patient's position or superimposed on the patient's lesion structure, and the fusion of the virtual and the real ensures the maximum exposure of the lesion structure on the basis of minimal trauma, and the effect of transparent tissue and organs. The accuracy and safety of the operation are improved, the operation efficiency is improved, and the operation time is effectively shortened.
Wu Xinghuo introduced that the Wuhan Union Hospital Orthopaedic Hospital took the lead in the use of the star map holographic imaging system in orthopedics in China, and it is the first in the world.
It is understood that at present, a set of MR equipment is worth more than 2 million yuan. In addition to orthopedic surgery, MR technology has applications in the fields of breast surgery, neurosurgery, and urology. There are several large hospitals in China. At present, the world's most advanced medical colleges such as Harvard Medical School have begun to introduce this system for clinical and medical education.

What is Mixed Reality Technology (MR)?
Mix reality (MR), which includes both augmented reality and enhanced virtual, refers to a new visual environment created by combining real and virtual worlds. In the new visualization environment, physical and digital objects coexist and interact in real time. It is a further development of virtual reality technology. By introducing real-world scene information in the virtual environment, the technology creates an interactive feedback information loop between the virtual world, the real world and the user to enhance the realism of the user experience.
Introduction to MR
Hybrid Reality (MR) is a further development of virtual reality technology. By introducing real-world scene information into the virtual environment, the technology creates an interactive feedback information loop between the virtual world, the real world and users to enhance the user experience. Realism.
Compared to VR and AR, mixed reality can be said to be the least known of the three, but what is interesting is that it may be the easiest way to enter the mainstream market.
The key to mixed reality is flexibility, which attempts to combine the advantages of VR and AR. In theory, mixed reality allows users to see the real world (like AR), but at the same time present a credible virtual object (like VR). Later, it will fix the virtual object in the real space, giving it a sense of realism.
For example, the characters that players see in "Pokémon Go" do not follow the rules of mixed reality. When encountering an elf, its distance does not change as the player moves. More directly, it is in the real world, and does not make people feel that it actually exists in the real world.
In mixed reality, the experiencer can feel the dependence between the virtual object and the real world. It also fully conforms to the perspective law of the real world. It will become larger when it is approached, and will become smaller after it is far away. This sounds great, but the application research on mixed reality is still in closed-door testing. Take the example of Magic Leap, which has received investment from giants such as Google and Qualcomm. The company has not publicly demonstrated its technology so far, and we don’t know anything about its related hardware products.
MR characteristics
Mixed Reality (MR) (both augmented reality and enhanced virtual) refers to a new visual environment created by the combination of real and virtual worlds. In the new visualization environment, physical and digital objects coexist and interact in real time. The system usually uses three main features:
1. It combines virtual and reality
2. In virtual 3D (3D registration)
3. Real-time operation
The implementation of Mixed Reality (MR) needs to be in an environment that interacts with the real world. If everything is virtual, that is the realm of VR. If the virtual information presented can only be superimposed on real things, it is AR. The key point of MR is to interact with the real world and obtain timely information.
The birth of MR
MR, which is both "Mixed Reality", is the mediation reality proposed by Steve Mann, the "father of intelligent hardware" by the University of Toronto professor, full name Mediated Reality.
In the 1970s and 1980s, Steve Mann designed wearable smart hardware to enhance the simplicity of his own visual effects and allow the eyes to "see" the environment in any situation. This is seen as an initial exploration of MR technology. .
VR is a pure virtual digital picture, while AR virtual digital picture plus naked-eye reality, MR is digital reality plus virtual digital picture. Conceptually, MR and AR are closer, half of the reality is half of the virtual image, but the traditional AR technology uses the prismatic optical principle to refract the real image, the angle of view is not as large as the VR angle of view, and the sharpness is also affected.
MR technology combines the advantages of VR and AR to better represent AR technology.
According to Steve Mann's theory, intelligent hardware will eventually transition from AR technology to MR technology. "The difference between MR and AR is that MR allows you to see the reality that the naked eye can't see through a camera. AR only superimposes the virtual environment regardless of the reality itself."
MR application
In general, the common carrier of virtual reality is smart glasses. Today, the first smart glasses that incorporate MR technology are in the development stage, and it will take some time before it goes into commercial use.
Conceptually, MR and AR are closer, half of the reality is half of the virtual image, but the traditional AR technology uses the prismatic optical principle to refract the real image, the angle of view is not as large as the VR angle of view, and the sharpness is also affected. In order to solve the problem of viewing angle and clarity, the new MR technology will be put into a richer carrier. In addition to glasses and projectors, the R&D team is currently considering the possibility of using helmets, mirrors and transparent devices as carriers.
MR prospects
Some research institutes estimate that by 2020, the annual sales of virtual reality devices will reach 40 million units worldwide, with a market size of about 40 billion yuan, plus content services and enterprise-level applications, with market capacity exceeding 100 billion yuan. Domestic first-line technology companies have joined the research and development of VR equipment and content, and in terms of content creation, there are already works such as super-dimensional MR, which will inevitably promote the transition of VR to AR and MR technology.
At present, there are relatively few companies and teams engaged in the field of MR in the world, and many of them are in the research stage.

The generic name of VTM Virus Sampling Tube is a single-use virus sampling tube, which is generally used for the detection and sampling of infectious pathogenic microorganisms in disease control departments and clinical departments. It is suitable for detection and sampling of influenza viruses (including general influenza, highly pathogenic viruses, H1N1 influenza virus, etc.), hand, foot and mouth virus, new coronavirus, measles and rubella and other types of viruses. VTM virus sampling tube can also be used for detection and sampling of Mycoplasma, Chlamydia and Ureaplasma urealyticum.
The virus and related samples in the VTM virus sampling tube should be stored and transported within 48 hours in a refrigerated state (2-8°C). Viruses and related samples can be stored for a long time in -80℃ environment or liquid nitrogen environment. The virus can maintain the activity of the virus in a lower temperature range, reduce the speed of virus decomposition, and improve the positive rate of virus isolation.
The VTM virus sampling tube is generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for different Partial sampling person. Moreover, the flocking swab is designed with a breaking point that conforms to the length of the sampling tube and the natural orifice of the human body, which is not only convenient for sampling but also convenient for transportation of the specimen.
