For the novice, laparoscopic surgery with the corner is not easy, the main surgeon if the temper is not very good, they will be more nervous! Analyze the reasons, simply attributed to the following: 1, the basic skills do not pass the basic skills do not pass, so the comrades usually do not try, the examination will be blindfolded. Now a lot of laparoscopic simulation training equipment, online can be bought anywhere, and then do not try really can not be said. Diligence can make up for clumsiness, more to think, more exercise will naturally be comfortable. 2, accustomed to the main knife, will not do the assistant accustomed to be the main knife, will not do the assistant, this also happens from time to time, many hospitals to invite fellow hospitals to do laparoscopic surgery performance, usually send the strongest lineup, but many doctors do the main knife to do a good job, change the direction and position, sometimes really do not know how to find it! Because they have been accustomed to a perspective, so it is important to think differently! 3, change the orientation, the instrument collision For the team with a small number of times, this one is very common, that is, change the operating position or direction of the time, the assistant two instruments east one head, west one head of the collision, the best way at this time is to be quiet, in accordance with the anatomical position of the current operating area in the abdominal wall positioning, only look at the abdominal wall, do not look at the monitor, in order to avoid blind operation may cause collateral damage. In order to avoid blind operation that may cause collateral damage, hold the mirror hand first to pull the perspective to the farthest, and then the assistant stick to the abdominal wall into the instrument, fast to the predetermined position to the abdominal cavity to explore the instrument, so that basically can accurately find the correct position. 4, the feelings of the first assistant to help the mirror hand only care about the main knife doctor, ignoring the feelings of the first assistant, to make good use of the adjustment of the near and far perspective, the appropriate time to back off the lens can avoid a lot of blindness on the operation, which is the embodiment of the big picture. 5, can not be accurately positioned 6, the price limits the hospital to carry out 3D laparoscopy
