Maxillofacial fixation system -- micro-plate for cranial and maxillofacial fracture fixation, designed for the surgical treatment of maxillofacial trauma fractures, suitable for the forehead, nose, orbit, zygomatic, maxillary region, and pediatric craniofacial bones.
The system is an orthopedic surgical instrument for neurosurgical tools. The maxillofacial fixation system includes micro-plates, straight plates, L-shaped plates, T-shaped plates, Y-shaped plates, double Y-shaped plates, H-shaped plates for cranial and maxillofacial fractures. The product range is complete, covering three-dimensional titanium mesh, self-drilling rotary bone screws, anatomical orbital floor plates, orthodontic nails, etc. However, the facial anatomical structure is special, and the screw plate needs to be placed away from the fracture line and avoid important anatomical structures such as nerves and teeth roots. Therefore, the specifications of the screw plate system are required to be as diverse as possible in order to be used in different bone structures, such as different radian, length, and number of screw holes. The bone plates forcranial and maxillofacial fractures are mainly divided into 1.5mm, 2.0mm and 2.4mm systems.
Titanium (including pure titanium and titanium alloy) is the most common material for hard tissue implants. Its elastic modulus and tensile strength are higher than those of human bone, and it is better than other metal materials such as nickel-titanium alloy and cobalt-chromium alloy in terms of biocompatibility and corrosion resistance. Our maxillofacial plate is made of titanium, and the self-tapping screws are mainly made of titanium alloy.
Jaw fractures include maxillary fractures and mandibular fractures. According to whether the fracture trauma is exposed, it can be divided into open fracture and closed fracture. Trauma is the most common cause of jaw fracture, which usually includes hit, traffic injury, fall injury, firearm injury, and a few iatrogenic injuries. All are caused by external forces acting directly or indirectly on the maxillofacial region. With the popularization of motor vehicles, the proportion of jaw fractures caused by traffic accidents has increased year by year, which has become the main cause of jaw fractures. In addition, neoplastic lesions in the maxillofacial region often lead to pathological jaw fractures.
In summary, maxillofacial fixation system has been widely used in clinical maxillofacial surgery, plastic surgery and ENT, and has a relatively mature market.

Loach conservation techniques involve several key steps to ensure a healthy and productive environment for the fish. First, the construction of a suitable pond is essential. The Jianchi Pond should be located in a sheltered area that receives ample sunlight, has a reliable water source, and allows for efficient drainage and irrigation. It should also avoid any risk of water pollution. The pond area should range between 100 to 150 square meters, ideally divided into smaller pools for better management, disease prevention, and feeding control. The depth of the pond is typically between 1 and 1.2 meters, with drain outlets placed 30 cm from the bottom. Anti-escape measures must also be installed. During winter, a plastic greenhouse should be built to maintain a warm environment and prevent freezing.
Before stocking, proper preparation is crucial. A 20 cm layer of mud should be laid at least 10 to 15 days prior to stocking. The pond should then be disinfected using appropriate agents. After one week, add 20 to 30 cm of water and introduce livestock manure at a rate of 0.3 to 0.5 kg per square meter. Then, add another 40 to 50 cm of water. Loaches should be introduced only after the water turns yellow-green with a transparency of 15 to 25 cm, which usually takes a few days.
When it's time to stock the loaches, choose healthy, disease-free, and active individuals. Ensure that the size of the loaches in each pool is consistent, and if necessary, they can be transported in batches. However, before placing them in the pond, all loaches must be immersed in a saline solution (2–4%) for 10 to 15 minutes to sterilize them. The stocking density is generally around 25 kg per cubic meter of water. As the loaches grow, the water level should be gradually increased to about 90 cm.
Effective management is vital during the holding period. Feeding should be done carefully, as loaches are omnivorous. They consume a variety of natural foods such as small crustaceans, aquatic insects, snails, cockroaches, animal organs, algae, rice bran, soybean residue, and leaves. A balanced diet combining both animal and plant-based food sources is recommended. Bait should be provided in a fixed location, at regular intervals, and in measured quantities. Avoid feeding when the water temperature exceeds 30°C or drops below 10°C.
Fertilization is also important. Every 4 to 5 days, apply well-decomposed manure to the pond at a rate of 50 to 100 grams per square meter to maintain water clarity between 15 and 25 cm. Regular water changes are necessary to keep the environment clean. Change 30 cm of water every 7 days, twice a week, to prevent water quality from deteriorating and reduce the risk of floating heads.
Disease prevention requires daily monitoring of the pond. Clean feeding areas regularly and apply bleaching powder every 10 to 15 days to maintain hygiene. These practices help prevent illness, reduce mortality, and ensure the overall health of the loach population.
