Description
Technical field
The utility model is related to the field of medical instrument technology, more particularly to a kind of laparoscopic surgery is heated with gas tube and is filled
It sets.
Background technology
Laparoscope Minimally Invasive Surgery is the invasive methods that a new development is got up, and is a certainty of the following operation method development
Trend.With advancing by leaps and bounds for industrial manufacturing technology, related discipline be fused to carry out new technology, new method established it is firm
Basis, in addition the operation that doctor is more and more consummate so that many past open operations have been taken and generation by intracavity operation now
It, considerably increases surgical selection chance.Retroperitoneoscopictechnique conventional method is to make three 1 centimetre small in patient's waist to cut
Mouthful, it is respectively inserted into a pipe-like service aisle for being called " trocar ", later every operation is carried out by these three pipelines；Again
The step same as open surgery is completed under television monitoring with special lengthening surgical instrument, reaches same surgical effect.
The advantages of Two trocars retroperitoneoscopictechnique is very it will be evident that being wound very little first, it is only necessary to 2 osculums, scar very little, this
Point is more worth noting for young man and the women to like to be beautiful.Second, it performs the operation as the entrance of single-broadsword event, to the damage of surrounding tissue
Wound minimizes, and the postoperative chance to stick together becomes smaller.Third, patient's postoperative wound pain are substantially reduced.4th, length of stay
It is less, as long as 2-3 days had can leave hospital, complete recovery of health and can devote oneself to work within 7 days, to keep patient burden expensive
It is big to reduce, while hospital bed turnover rate is accelerated.Two trocars Retroperitoneoscopicvaricocelectomy and laparoscope urological surgery can be used at present
