Background technology
In the research of medical science, researcher generally selects various experimental animals and replicates disease model, to study it
Pathogenesis, pathological change etc..Wherein it is no lack of the lactations such as selection rat, mouse, new zealand white rabbit, beasle dog and miniature pig to move
Thing.In conventional animal experiment, in order to preferably observe required position or the needs due to operation, often using surgical forceps
Or haemostatic clamp clamping soft tissue.But for the tender lung tissue of quality, (such as in lung's surface of a wound sealing operation), use operation
The instrument such as tweezer or haemostatic clamp clamps lung tissue, often results in tissue damage, even results in animal lung gas leakage.Due to animal
Lung is an organ constantly moved, and even if treated not damaged tweezer can not also avoid that animal lung is caused to damage, lung
Tissue often leads to lung's atrophy, this greatly adds the difficulty of experiment once gas leakage occurs；Lung's target surface of a wound in operation
Be difficult to find, result in the inaccuracy of experimental result.
Further, since the lung of baby is more fragile, in general surgical operation, conventional operating theater instruments is to baby lung
Cause the possibility of damage bigger, and in surgical procedure, because baby's lung surface area itself is little, the gas leakage of the surface of a wound is led
Baby's lung atrophy is caused, this make it that the visual field is easily affected in surgical procedure, and this considerably increases the difficulty of operation and risk.
