"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
Esophageal stent is cylindrical in shape with one end or both ends being trumpet shaped, cup shaped, spherical, mushroom shaped, etc. It generally has the following characteristics:
(1) Ti Ni shape memory alloy self expanding stent has excellent biocompatibility, corrosion resistance, memory properties and super elasticity. In the environment of 0-10 ℃ (or ice water), the stent is softened, and its shape can be changed within a certain range, which is easy to put into the implant. In the human body (the ambient temperature is more than 33 ℃), the stent can be released from the implant and gradually restored to its original state. The stent produces a continuous and gentle radial dilation force, which acts on the inner wall of the esophagus to gradually expand the stenosis and restore patency.
(2) The stent has good hyperelasticity under body temperature and can comply with the peristalsis of the esophagus, so as to keep the esophagus smooth without too much discomfort. The structure of woven stent is specially designed to reduce the discomfort of patients.
(3) Both ends of the stent are smooth without sharp corners or burrs, which can significantly reduce the damage to the esophageal wall.
(4) The silicone rubber film coated on the stent surface has good biocompatibility, which can effectively prevent the growth of granulation in the esophageal wall and the reflux of gastric juice and food.
Main classification
(1) Knitted esophageal support
Knitted esophageal stent has all the functions of ordinary esophageal stent. Its biggest feature is that the specially designed structure of the stent can adapt to the peristalsis of the esophagus, with little damage to the esophagus, and effectively reduce the patient's foreign body sensation. The knitted esophageal stent is placed with a binding implant, which is more accurate, convenient and safe.
(2) Recoverable esophageal support
The recyclable esophageal stent is specially designed for benign stenosis and short-term closure of fistula. The stent is fully covered with film, and the film is more than the end edge of the stent, so as to minimize the occurrence of stimulating hyperplasia and facilitate recovery; The recovery line at the edge of the bracket is convenient for tightening the expanded end edge of the bracket during recovery, so as to facilitate recovery; The stent with extracorporeal recovery line is very convenient to recover; The bracket without external recovery line is provided with special recovery tools to facilitate recovery.
(3) Membrane anti backflow bracket
The membranous anti reflux stent adds a reflux valve on the basis of the membranous stent of the esophagus, which can simulate the function of the cardia and reduce the occurrence of reflux esophagitis and other complications.
(4) Stent for gastric fundus fistula
The stent for blocking gastric fundus fistula has a unique mushroom shaped umbrella, which is closely attached to the gastric wall at the bottom of the stomach, effectively preventing stomach contents from flowing back into the chest through the fistula; The double mushroom shaped stent body (esophagus) has a larger contact area with the esophagus, and the fixation is stable.
