Description
Technical field
This application involves a kind of medical instruments, and in particular, to a kind of laparoscope antifogging and dustproof camera lens.
Background technique
Laparoscope is a kind of surgical instrument for prying through intraperitoneal situation using miniature webcam and complete corresponding surgical procedure.
Light source provides illumination through light source conduction path, lens of laparoscope is inserted into through incision of abdominal wall intraperitoneal, is imaged with digital camera
The situation of abdominal cavity inner tissue and organ is sent to image processing system by image receiving path by technology, is finally shown in display
On device, operation etc. is completed with operation instrument to assist performer to carry out intraperitoneal detect.
For patient safety angle, operating room environment temperature is low relative to body temperature, and lens of laparoscope is through incision of abdominal wall
When being inserted into intraperitoneal, because of the intraperitoneal outer biggish temperature difference, part vapor is easy agglutination in colder lens of laparoscope, thus
Fumulus is formed on lens of laparoscope, influences the clarity in the pried through visual field of lens of laparoscope, and then is influenced to check or be performed the operation
Process.
With the progress of operation, lens of laparoscope temperature is increased, but is cut using electricity knife of peritoneoscope, laparoscope coagulation hook etc.
Tissue debris, flue dust caused by operation due to CO2 pneumoperitonium presence and be attached to lens of laparoscope surface, further plus
Acute blurring of vision causes performer to be unable to judge accurately the depth of tissue and blood vessel, and then increases in operation and accidentally injure surrounding tissue
And the risk of vitals.
Lens of laparoscope is fetched into repeatedly outside abdominal cavity wipe the methods of antifog reagent or hot-water soak there are it is ineffective,
Inconvenient, extension operating time reduces the drawbacks such as lens of laparoscope service life, and current existing heated type lens of laparoscope is still deposited
In the latent dangerous factors such as surrounding tissue and blood vessel, electric leakage of burning, brush lens of laparoscope greatly increases lens of laparoscope
Abrasion.
Therefore, it is necessary to provide a kind of antifogging and dustproof lens of laparoscope to solve the above problems.
Summary of the invention
Technical problems to be solved in this application are to overcome existing design and technological deficiency, provide a kind of antifogging and dustproof abdomen
Hysteroscope camera lens, it can prevent lens of laparoscope from hazing when just entering patient's body by hydrophobicity plated film fog-proof lens, by anti-
Dirt component reach not because caused by electricity knife of peritoneoscope, laparoscope coagulation hook etc. tissue debris, flue dust be attached to lens of laparoscope table
The purpose of face and blurring of vision makes performer obtain good surgical field of view, reduces because wiping lens of laparoscope extended hand
The art time, while reducing because the lens of laparoscope abrasion caused by wiping avoids heated type while shortening operating time
Antifog lens of laparoscope burns the potential risk of abdomen inner tissue, organ, also reduces erroneous estimation tissue, blood due to blurring of vision
Pipe depth in turn results in the probability of its unnecessary damage.
The application is achieved through the following technical solutions：Antifogging and dustproof lens of laparoscope, including gripping handle, laparoscopic tube,
Light source conduction path, image receiving path, dust-proof airway path, fog-proof lens, dust preventing component, the gripping handle and the abdomen
Hysteroscope pipe, which is connected, constitutes abdominal cavity shank, and the light source conduction path, dust-proof airway path, fog-proof lens, is prevented at image receiving path
Dirt component is closely embedded in the abdominal cavity shank.
Further, the fog-proof lens outer surface is coated with silicon dioxide layer, and silicon dioxide layer is cladded with magnesium fluoride layer, dioxy
SiClx layer, magnesium fluoride layer are with a thickness of 70-90nm.
Further, the dust preventing component is made of annular fan-shaped air drain, dust-proof exhaust guide hole and air inlet access aperture, dust-proof
Exhaust guide hole is located in annular fan-shaped air drain and is centrosymmetric, and dust preventing component realizes dust-proof mesh via dust-proof airway path
's.
Further, the dust-proof exhaust guide hole is 8-16, diameter 0.5-1.5mm, is inverted funnel shape structure.
Further, the air inlet access aperture outer diameter is 10-15mm, and is equipped with 5-8 layered tower non-slip groove.
The beneficial effect of the application is：Silicon dioxide layer and fluorination are coated on the eyeglass of this kind of antifogging and dustproof lens of laparoscope
Magnesium layer, magnesium fluoride layer can achieve the antifog purpose of hydrophobicity, and silicon dioxide layer increases film adhesion, wearability and anti-impact
Hitting property；Arrange in pairs or groups dust-proof airway path of dust preventing component forms a gas curtain in front of fog-proof lens, thus reach do not enable electricity knife of peritoneoscope,
Tissue debris caused by laparoscope coagulation hook etc., flue dust are attached to the effect on lens of laparoscope surface, and then obtain performer
To good surgical field of view, extended operating time is reduced because wipe lens of laparoscope, while caused by reducing because wiping
Lens of laparoscope abrasion, shorten operating time while, avoid heating type antifog lens of laparoscope and burn abdomen inner tissue, device
The potential risk of official also reduces erroneous estimation tissue, vessel depth due to blurring of vision and in turn results in its unnecessary damage
Probability.
