Description
Technical field
This utility model relates to a kind of medical assistant product field, particularly a kind of anti-smog device for endoscope lens.
Background technology
Along with the development of modern medicine, clinical operation strides forward to Wicresoft in the epoch, and wherein endoscope is as a kind of conventional medical apparatus and instruments assistant product, is widely used in clinical Minimally Invasive Surgery.The structure of current endoscope is become by flexible part, light source and an arrangement of mirrors head group.During use, endoscope lens is the natural hole by human body, or the minimal incision * that underwent operative is done enters in human body.Because endoscope can import the organ of preliminary examination, the change of relevant portion directly can be spied on.The quality of endoscope lens picture quality directly affects the result of use of endoscope, also indicates the level of development of endoscopic technique.
But, in use, because endoscope head is generally metallic article, surface temperature is lower in actual endoscope, lower than room temperature, when entering patient's in-vivo procedures, patient temperature at 36-37 DEG C, due to the difference of endoscope head and patient temperature, there is larger temperature difference, part water vapour is very easy to cohesion after running into the lower endoscope lens of surface temperature, formed one deck mist, thus greatly affect endoscope lens visual area definition over the display within short several seconds time.Therefore, the quality of the anti-fog effect of endoscope lens, direct relation the success or failure of operation.
Enter for endoscope lens the problem that steam is easily condensed on human body rear lens surface, the antifog means of current domestic endoscope camera lens mainly adopt following methods:
1. physics anti-fog method
It is a kind of method adopting hot salt brine preheating camera lens, it is a kind of traditional anti-fog method, particular by endoscope lens is inserted before abdominal cavity through perforator, endoscope lens is put into the physiological saline solution of about 70 DEG C, and preheating 5min, its mechanism can raise the temperature near camera lens front end in the short time, before entering human body again after making it taking-up, temperature and the Intraabdominal temperature of endoscope head surface are close, thus stop water vapour to continue cohesion;
2. chemical anti-fog method
The method adopts conventional povidone iodine cotton balls, spray-proof oil, disinfectant liquid for skin cotton balls, ethanol or silicone oil to carry out wiping endoscope head surface, makes its surface form layer protecting film, to weaken the adhesive force of steam on endoscope lens, to reach the effect of demist;
3. biological anti-fog method
Omentum majus wipe method, its concrete grammar is, inserts veress needle, by veress needle by CO at the umbilical part of patient
2gas pushes to treats patient's abdominal part, after patient's abdominal tympanites, extracts veress needle, then changes endoscope, and by camera lens from puncture needle insertion abdominal cavity, on intraperitoneal omentum majus, wiping camera lens carries out antifog process; The method of application omentum majus wiping, owing to carrying out at intraperitoneal, camera lens and temperature in peritoneal cavity are comparatively close, and camera lens not easily hazes.
At present in above-mentioned three kinds of methods, its deficiency is respectively: physics anti-fog method, and need the normal saline realizing providing 70 DEG C, preheating time is longer, operates comparatively loaded down with trivial details; Chemistry anti-fog method, because need endoscope camera lens surface smear chemical substance, life-time service can damage endoscope lens, and chemical agent remains camera lens easily to tissue generation infringement; And omentum majus wipe method, be only only applicable to laparoscopic surgery at present, cannot be applicable to peep operation in other positions.
