Laparoscopic surgery is thought from coming out, and always in fast-developing and variation, is mainly shown as new operative model or hand
Art type is constantly created and is promoted, and is performed the operation known to numerous doctors（Such as Cholecystectomy）Also continuous
It improves and optimizes.Generally, operation type gradually increases, and the operation that can be completed becomes increasingly complex, in operation used in
Instrument type is also more and more, and the method that puncture channel system is built in operation is also constantly improved or optimized.Such as it is a kind of
In uterectomy, a part of doctor, which generally selects, establishes 1 10mm puncture channel and 3 5mm puncture channels, and crushing is picked-off
It is the channels 15mm again to expand one of channels 5mm when uterus；And another part doctor generally selects and establishes 1 10mm puncture
Channel and 3 5mm puncture channels, crushing additionally establish a 15mm puncture channel again when picked-offing uterus.Such as a kind of stomach is cut
Except in operation, a part of doctor tends to " 5 puncture channel method ", i.e. 1 channel 10mm, 1 channel 12mm, 3 channels 5mm.
Another part doctor tends to 6 puncture channel methods, i.e. 2 channels 10mm, 1 channel 12mm and 3 channels 5mm.Such as abdominal cavity
Develop in videoendoscopic surgery earliest and apply most ripe one of operation --- Cholecystectomy, all the time 4 tiretube process of generally use,
2 large diameter puncture channels and 2 small internal diameter puncture channel are established in patient's stomach wall, are completed with 3 doctors.In recent years
