Methods Interfixation by crossing kirschners wire,transfixation ligation by steel wire of "8" after replacement of the dislocation of acromioclavicular joint.
Objective To explore a new approach on the avulsion fracture of tibial insection of anterior cruciate ligament with arthroscopic reduction and steel wire internal fixation.
By improving the BTR1-PST286 wish single sucperd hydraulie trepanner made in Germany.Realize adjustable of electric line.preventing accidents of electric line or stecly line fall down.
Materials and Methods: The 40 moloar teeth without alveolysis within one week, were tied with steel wire, treated with root cannel filling or resinifying therapy.
An intelligent clothes rack is developed with a block installed on the end of each knighthead,around which steel wire is enwind and connected to a DC motor and the clothes rail.
In order to lower residual heat on the surface of the block,the cooling mans is installed in interwall of the block.The wortle is soaked in cooling watr to reduce its working temperature.
