In trauma it can be stated that some kind of consensus across the world exists nowadays about the use of Ilizarov methods in cases of trauma sequelae like limb shortening, bone defects, malunions, and osteomyelitis. A general statement about indications for the Ilizarov method in trauma is that the method should be considered in any situation where surgeon feels inconvenient with internal fixation. Also a suggestion should be added that the more severe fracture is, the more the Ilizarov method is suitable for the case.
The following most common trauma indications for the Ilizarov method should be considered:
• Severe open fractures with major soft tissue damage
• Limb salvage in fractures combined with vascular injuries
• Open fractures with bone loss
• Intra and periarticular fractures:
• tibial plateau and pilon fractures
• distal femur,
• distal radius
• foot
• elbow
• Intra and periarticular fractures with diaphyseal extension
• Implant failures, refractures, fractures in conditions of pre-existing limb deformities

Orthopedic Medical Devices, How To Get Out Of The Cycle Of Made In China?
With the increase of China’s aging population, “health” topic has attracted more and more attention to advanced medical equipment has become the hospital’s “pet”. In today’s high-tech driven, easy to use, intelligent medical devices medical device research and development and innovation focus. In recent years, China’s medical equipment also tasted the benefits of industrial development, rising exports and dividend policy for medical devices medical devices industry’s development into a “honeymoon period”. However, behind medical devices industry, innovation has become a big problem. Now developed into a following Europe and the development of medical devices, only the “made in China” of the cycle, in particular multidisciplinary orthopedic medical device, “innovation” has been dare not touch the pain point enterprise, the Orthopedic medical device innovation?
Found in the research and development process, orthopedic medical device is a multidisciplinary and knowledge-intensive industries, designers and developers of medical devices is not necessarily the real users, and users of products–doctors and patients, and did not know how the biological sciences, which created difficult orthopedic medical device product development. So, how do we solve this dilemma?
In sales while also focusing on customers and patients feel, “sales” and “research and development” way of combining cross orthopedic medical device innovation challenge.

Medical Equipment Enterprises In Three Multinational Companies Have The Final Say To Sprint Import Substitution
In 2016, the country continues to release policy positive, driven by domestic medical device manufacturers complete import substitution is then entered a crucial year, multinational medical device giant remains the greatest opponent: they still hold a high-end medical equipment market “initiative”, high-end market coverage of 85% on one side and “localization” layout of unboiled water.
Just look at the price, it will recognize that time has passed, the local medical device manufacturers “import substitution” campaign broken?
Three major multinational medical device giant GPS (GE, Philips, Siemens) was absent for the first time this year, the 76th CMEF (China International medical equipment fair).
This in circle is article medium of news: said big, is because as industry event, CMEF has held has 76 session, in previous years often in exhibition Shang on directly broke procurement big single, GPS collective absent can be described as incredible; said is unlikely to, is because from last year began, including GPS zainei of devices manufacturers on gradually released news, future will no longer participate in autumn exhibition, “collective absent” also can said is in expected within.
On the face of it, including the shadow, MINDRAY, homemade, Neusoft medical equipment manufacturers to replace GPS became the main force of this exhibition, which is a bit like a microcosm of China’s 300 billion medical device market, made in China is emerging, import substitution wave really hit. Despite the ferocious momentum of multinationals “localization” strategy, this alternative is not easy.
Data displayed in the current Chinese medical device market accounted for 14% of the total pharmaceutical market share, this world is 42% a global medical device industry is expected to average annual growth of 4.1%, but China’s nearly six-year compound annual growth rate reached 20%, the medical device market in China can be described as “fat”, who wants to compete.
“To use efficient methods to catch up with the import manufacturers. If you want to compete with GPS positive, is very difficult, so you need to use some method of differentiation, in specific markets to pursue. “MINDRAY medical Chairman chengming and revealed the first financial daily in an interview.

Difference Between Drills And Hand Drill
Drill just resorting to motor drive gears increase the strength of drill bit rotation, drills in metal. timber. material does scrape through.
Impact drill, drill chucks knob, adjustable drilling and impact drilling in two ways. but the impact drill is the use of gear on the shaft beating each other to realize the impact, but the impact is much less hammer. it can also drill reinforced concrete, but less effective.
Hammer is not the same, it is the use of motors driving two sets of gears on the bottom structure, a set of its drill, and the other a drive piston, hydraulic engine strokes, have a powerful impact, along with drill results. force can crack stone gold.
Electric pick is motor driven lashes left mound jumping running, so pick a gouge ground effects.
Picks are used in hydraulic pump, air compressor pump in the transmission gas pressure-driven electric pick hammers bouncing back and forth to produce picks gouge ground effects, but electric pick only chisel, its pick does not turn.
Summary drill drill drill drill drill and hammer drill hammer effect can higher hammer electric pick only the hammer does not drill.

Medical Equipment Maintenance Principle And Method
1. Repeated failure in person (if it can be repeated), do not believe the user or a third party dictating or paraphrased.
Careful observation, oral not gullible users, especially third party reporting. Some operators in order to evade their responsibilities, said instruments himself … and he didn’t move, etc. These are understandable. Engineers should be properly dealt with.
2. External and internal.
Don’t be so ready to open the Cabinet, no preliminary judgement and excluded veteran likes to roll out the stall is not practice. Expect to open the Cabinet to see where there is a break or apparent failure, purely on luck, even if good luck cannot in every case.
About 50% fault is determined by external environmental or operations, caused by cleaning. Such as whether to shut down for a long time? Whether there is a great temperature difference between day and night?
Apparatus location is near the elevator? Equipment near what equipment is in use? Computer is set up correctly? For a while.
3. Power supply, after the hosts first annex, after the hosts.
Should first check whether the stability of the power supply, the load is too heavy and the ground is good, electrodes and other accessories are good and normal, the interface is correct.
4. Take full advantage of the instrument panel buttons, display screen and operation or maintenance procedures, exclusion, which need to be extremely familiar with the structure.

Focus On The Development Of High-Performance Medical Equipment Away From Dependence On Imports Of Medical Devices
Made 2025 China has clearly put forward to enhance the medical device innovation and industrialization, focusing on the development of high performance equipment, from the high-end medical equipment import-dependent situation.
Currently domestic appliances the overall scientific and technological level 10 years gap with developed countries or regions, mainly in small scale, weak competitiveness; insufficient research and development funding domestic medical institutions buy and use homemade devices lack of policy support national industrial base is still a little weak.
Technology aggregation and concentration is the key to large medical device industry stronger, needs world-class research teams, industry leading and high levels of venture capital project third party connection, can bring the high-end medical equipment. Strengthening cooperation with the high level of scientific research institutes, national applied research projects to industry, complement, the efficient use of resources.
Our high-end medical equipment development, needed to break the foreign giants in a monopolistic situation; should pay attention to “the Internet” thinking through the consolidation of resources, develop the medical devices area of medical services, including medical devices to the Internet, data centers independent software, personalized products such as shared medical clinical samples.
Large sophisticated diagnostic equipment such as CT, MRI, MRI class, such as nuclear medicine and angiography machine DSA has long been “GPS” (GE United States GE, Philips Netherlands Philips, Siemens Germany Siemens) by foreign giants such as monopolies.
Multinational medical device companies take advantage of market dominance and keep raising the prices of products and services. Aftermarket and consumables area, prices for imported medical equipment year warranty from 6% of the contract costs soar more than 10 years ago to the current 15%.
