Description
Technical field
The present invention relates to medical aid fields, more particularly to one kind to be used for the antipollution air-flow protection of laparoscope mirror surface
Set.
Background technique
Laparoscopic minimally invasive surgery is to absorb visual area image by lens of laparoscope, by image transmitting to display screen, is performed the operation
Doctor implements operation when watching display screen.It can be said that lens of laparoscope is operating team's " eyes ", therefore keep laparoscope
The cleaning of camera lens is clearly most important to a laparoscopic surgery is smoothly completed.However, can be often because of camera lens in laparoscopic surgery
Mirror surface by it is various pollution and be forced to interrupt, by mirror surface it is clean after, be further continued for performing the operation.Wipe eyeglass when need to by laparoscope from
It stabs mouth (Trocar) to extract out, after instrument nurse wiped clean, then laparoscope is pushed into and stabs mouth.One operation need to wipe several times,
Ten several times even tens times.For surgeon, this wiping can break the continuity of operation, especially crucial in operation
When such as encounter big bleeding, dissection dead angle position when, seize every minute and second, camera lens is hazed or is contaminated, and directly results in hand
Art doctor " blindness " (can not see surgery location clearly causes operation to be interrupted), seriously affects the mood of procedure and operative doctor,
Even cause Accessory injury.Even if the number of wiping can be effectively reduced by the cooperation for promoting team；But in clinical practice,
Almost every laparoscopic surgery can all encounter the case where wiping mirror surface, and performing the operation, bigger, operating time is longer, and the probability of appearance is got over
It is high.
