Description

Irrigation aspirator for laparoscopic surgery

Technical Field

The utility model relates to the technical field of irrigation attractors, in particular to an irrigation attractor for laparoscopic surgery.

Background

Laparoscopic surgery is a newly developed minimally invasive method, and is a necessary trend for the development of future surgical methods. Along with the rapid progress of industrial manufacturing technology, the fusion of relevant disciplines lays a firm foundation for developing new technologies and new methods, and doctors are more and more skilled to operate, so that a plurality of past open operations are replaced by intracavity operations at present, and the operation selection opportunities are greatly increased. The traditional method of laparoscopic surgery is to make several small incisions of 0.5-1 cm in the chest and abdomen of the patient, each of which is inserted with a tubular working channel called trocar, and all the subsequent operations are carried out through these several tubes; and then the special lengthened surgical instrument is used for completing the same steps as the open surgery under the monitoring of a television, so as to achieve the same surgical effect. The advantages of single port laparoscopic surgery are very clear, firstly the trauma is small, only a single small incision is needed, and the scar is small, which is more noticeable to young people and women loving beauty. Second, the surgery is a single-knife straight-in access, the damage to surrounding tissues is minimized, and the chance of adhesion after surgery is reduced. Third, the pain of the wound of the patient after operation is obviously relieved. Fourth, the number of hospital days is small, some hospital can be discharged only in 2-3 days, and the patient can be completely recovered in 7 days and put into operation, so that the burden cost of the patient is greatly reduced, and meanwhile, the turnover rate of the hospital bed is accelerated.
