Description
Technical field
The invention belongs to technical field of medical auxiliary equipment, and in particular to a kind of demister of lens of laparoscope.
Background technique
It is well known that lens of laparoscope is equivalent to " eyes " of operator in laparoscopic surgery, it can be worn by one
Acanthopore enter it is intraperitoneal carry out comprehensive observation, can " eyes " of nowadays operator can always be covered by one layer of fog, that
It is the temperature due to lens of laparoscope lower than intraperitoneal temperature, it is intraperitoneal to have between camera lens after camera lens enters abdominal cavity
The temperature difference, so that intraperitoneal hot gas forms fog on camera lens surface quickly and camera lens is made to form fringe, in response to this,
Common are three kinds of solutions: the first, lens of laparoscope merging temperature is before the start of the surgery 60 ± 10 DEG C by instrument nurse
Sterile saline in preheat 1min or so, then camera lens is placed in rapidly it is intraperitoneal, when camera lens temperature is higher than temperature in peritoneal cavity
When, vapor, which would not liquefy on camera lens surface and form fog, influences sight, but in the course of surgery, the hot salt in container
Water need to be replaced at any time according to water temperature condition.In this way, it is not only time-consuming and laborious, but also using very inconvenient.The second, Iodophor wiping is anti-
Camera lens, i.e., is first wiped the front end of camera lens by mist method before being placed in abdominal cavity with Iodophor cotton balls, then extra Iodophor is wiped with dry cotton ball.
Iodophor is a kind of unformed compound containing iodine, and character is smooth, can form layer protecting film on camera lens surface, be isolated intraperitoneal
Hot gas is attached to camera lens, plays antifogging action.This method has the disadvantage in that anti-fog effect effect in 30min is preferable, but
Less effective after 30min still needs to again or repeatedly carry out anti-fogging measure when operating time is longer.Third, spray-proof oil are antifog
Method first extracts a little spray-proof oil out with sterilizing syringe before lens of laparoscope enters abdominal cavity, then directly drip on camera lens top or
It instills on cotton balls, then is uniformly applied to lens of laparoscope top, with antifog view.Spray-proof oil can form one layer single point on camera lens surface
The hyaline membrane of son, the hyaline membrane can prevent Water vapor condensation at droplet.But it is mostly for the spray-proof oil of scope currently on the market
External import, it is expensive, increase the burden of patient.
To sum up, be badly in need of it is a kind of can be more convenient in laparoscopic procedures, it is faster, it is more inexpensive, more effectively progress abdomen
The device of hysteroscope camera lens demisting.
