Description
Technical field
The invention belongs to the hard mirror of medical equipment, soft lens technology technical field, in particular to a kind of road Shuan Qian single hole is flexible
Laparoscope system.
Background technique
Modern surgery continues to develop health demand and excellent with scientific and technological progress, the raising of Medical treatment level and patient
Change.Booming minimally invasive surgery is exactly surgical principle and patient opponent of the surgeon for " reduce wound, palliate the agonizing sufferings "
The requirement of art " painless, without scar, small wound " and the inevitable outcome constantly explored.
Surgery is introduced the minimally invasive epoch by the laparoscopic technique that last century the nineties are risen.From world's the first laparoscopic cholecystectomy
For resection to the introducing and integration of micro-wound operation robot platform, the development of minimally invasive surgery is swift and violent, traditional at present various to open abdomen
Operation has shifted towards conventional laparoscopic, single-hole laparoscopic surgery operation.However, single-hole laparoscopic technology is not the same as conventional laparoscopic skill
Art generally rapidly changes the operation habit of surgeon, and reason is all instruments in art while occupying the space that unique stamp blocks,
This causes instrument to interfere with each other, it is difficult to which formation operation triangle, the operation difficulty of operation is big, learning curve is long；Single notch simultaneously
Diameter is big, and actual minimally invasive income is limited.In view of this, related practitioner attempts to increase single-hole laparoscopic technology by bending instrument
Operability, but because of the defect of stiff rod instrument itself, and particular instrument is only capable of completing specific operation, and single-hole laparoscopic technology is still
It is difficult to popularize.
Endoscopic technique all promotes the continuous development of medical career in the period of different, and endoscope is one equipped with light
The pipeline in source, it can be entered in stomach with direct oral cavity or enter internal corresponding site through other natural holes.It can be with using endoscope
See the lesion that X-ray cannot be shown, therefore it is highly useful to doctor.For example, doctor can observe in stomach by gastroscope
Ulcer or tumour make optimal therapeutic scheme accordingly.The endoscope clinically used is usually soft lens, and outer diameter is thinner,
Generally in 10mm or so, shank is more soft, flexible, can carry out large scale bending, completes relevant operation.Currently, being solved under scope
Certainly the means of surgical disease also continue to develop.But its soft flexible characteristic, it is insufficient to also result in its rigidity, it is difficult in abdominal cavity
Satisfied positioning is obtained, executable operation is also less.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of flexible abdomens of road Shuan Qian single hole
