"With a grateful heart, we can efficiently complete the present thing at hand. The reasonable thing is training, and the unreasonable thing is training. In short, the reasonable and unreasonable thing is practice. We can survive within eight hours, and develop beyond eight hours. We can win when others rest by sticking to habits, making habits natural, and making nature cultural." As for the above words, we have a partner and a general manager who shared with our employees that "seeking development beyond eight hours is a second career...". Question: It is absurd for any government or any enterprise to rush to the second job after eight hours for backbone, elite and senior executives! It is possible for a nanny to take part-time jobs. Either the general manager has a problem with his understanding, or the general manager has ulterior motives. It is no wonder that the partners vary widely. Some first deal with the manufacturer's salesmen and specialize in evil ways; Some sneak around, steal some technology, engage in some processing; There are thousands of ways to succeed in life. However, some people prefer to be animals rather than people by any means for money. However, some people are very particular about life. Those who achieve great things and lead the world are all people who are very particular about the 'living method of life'.

Ni-Ti shape memory alloy biliary stent
At present, the most widely used biliary stent is the braided mesh stent made of titanium and nickel shape memory alloy (as shown in Figure 2), which is straight cylinder and one end or both ends are flares. The treatment of malignant biliary obstruction with biliary stent is minimally invasive, repeatable, and can effectively relieve malignant biliary obstruction, which is comparable to surgical shunt. Ti Ni shape memory alloy biliary stents are generally self expandable. Observe the stent expansion during implantation, and use balloon expansion if necessary. It is applicable to extrahepatic common bile duct obstruction or stenosis caused by various malignant diseases. It has the following advantages:
(1) Ti Ni shape memory alloy self expanding biliary and anastomotic stent has excellent biocompatibility and corrosion resistance, as well as unique memory properties and super elasticity. The inner bracket is softened under 0~10 ℃ (ice water), the shape is changed within a certain range, and it is put into the transmitter no more than 10F; When the internal stent is pushed out above 33 ℃, it can immediately return to its original shape, generating a continuous and gentle radial expansion tension, which acts on the inner wall of the biliary tract, making the narrow part smooth. Its radial support force is greater than 6 N.
(2) The stent has good hyperelasticity under body temperature, and can fluctuate with normal biliary tract peristalsis, so that the biliary tract can be kept smooth without discomfort.
(3) The two ends of the internal stent are small arcs, which will not damage the biliary wall. The operation is simple and effective.
(4) It can prevent bacterial infection and stent blockage caused by bile mud deposition.
