Put.
Background technology
With the development of modern medical techniques, micro-wound surgical operation is clinically carried out extensively, and laparoscopic surgical techniques
It is the important component of surgery minimally invasiveization.Laparoscope be melt machinery, electricity, optical technology in one advanced Medical Devices,
Laparoscopic surgery is exactly to provide illumination using cold light source, and lens of laparoscope (about 10 mm) insertion is intraperitoneal, with endoscope skill
Art and image display technology carry out analysis judgement to the state of an illness of patient, and are performed the operation with special laparoscopic instrument, but
It is that the phenomenon that lens of laparoscope hazes often occurs in laparoscopic surgery operating process, causes surgical field of view unintelligible, puzzlement is faced
Bed medical personnel.Its main cause is that abdominal cavity internal-external temperature difference is larger, when intraperitoneal part water vapour runs into cold lens of laparoscope
After be condensed into one layer of fine liquid particles, so as to form one layer of mist, influence the definition of the visual field over the display.Clearly surgical field of view
It is the key of laparoscopic surgery safety, therefore the antifog processing of hysteroscope camera lens is most important.It is now clinically to use physiology salt more
Water heating, Iodophor wipe, tissue wipe method progress camera lens is antifog, but still suffer from some shortcomings or deficiency, such as physiological saline
Heating time is long, and needs the physiological saline that regularly more exchanges heat, and wastes time and energy；Iodophor is colored liquid, and Iodophor is wiped
Also need to be wiped with dry cotton ball after wiping, in case unnecessary Iodophor covering camera lens, influences judgement of the patient to abdominal visceral browser color, and
Some patients have its limitation to iodine allergy.When it is intraperitoneal have more watery blood when use tissue wipe method, often more wipe more mould
Paste.
Utility model content
Part in order to overcome the above-mentioned deficiencies of the prior art, it is disposably antifog that the utility model provides a kind of lens of laparoscope

One end open is closed in hysteroscope hole one end, and heater is sealed in laparoscope hole blind end with sealant, and heater is in laparoscope
End face of the hole openend in addition to the aperture in laparoscope hole is sealed by sealant, and packaging is additionally provided with heater periphery
Bag.
Further, the blind end of described heater by being followed successively by sealant, zone of heating and sealant inside outside.
Further, described air-permeable layer is non-woven fabrics.
Further, described zone of heating is put including the galvanic cell device that activated carbon, iron powder, salt and water are formed
Electrical heating.
Further, described galvanic cell device Exotherm Time is 4~6h, and exothermic temperature is 60~75 DEG C.
Further, the long 25cm of described heater, a diameter of 8cm.
Further, the periphery of described heater is provided with the fixing device for being used for fixing heater.
Further, the blind end of described heater is provided with the fixing device for being used for fixing heater.
Further, described fixing device is double faced adhesive tape.
Further, described packaging bag is provided with the strip of paper used for sealing for being easy to Kaifeng.
The beneficial effects of the utility model are：The utility model is simple in construction, easy to use, mitigates lens of laparoscope and hazes
Phenomenon, increase surgical field of view, meet the needs of clinical laparoscopic surgery, operating time is shortened with this, reduces laparoscopic surgery
Complication, and cost is cheap, easily fabricated, good antifogging effect.

Embodiment
The utility model is further illustrated below according to drawings and examples.
As shown in Figure 1, Figure 2 and Figure 3, the disposable antifog heater of a kind of lens of laparoscope, described heater master
Body is tubular, and the endoporus of pipe is all as the laparoscope hole 5 to match with lens of laparoscope, the inwall in laparoscope hole 5
Sealant 4, the outermost periphery of pipe is air-permeable layer 3, is zone of heating 2 between sealant 4 and air-permeable layer 3, laparoscope hole 5 one
End seal closes one end open, and heater seals in the blind end sealant 4 of laparoscope hole 5, and heater is open in laparoscope hole 5
Hold the end face in addition to the aperture in laparoscope hole 5 to be sealed by sealant 4, packaging bag 6 is additionally provided with heater periphery.
Described air-permeable layer 3 is non-woven fabrics, and the air permeable effect of non-woven fabrics is good.
Described zone of heating 2 includes the galvanic cell device that activated carbon, iron powder, salt and water are formed and carries out electric discharge heating.
Described galvanic cell device Exotherm Time is 4~6h, and exothermic temperature is 60~75 DEG C.
Described heater long 25cm, a diameter of 8cm.
The periphery of described heater is provided with the fixing device 1 for being used for fixing heater.
The blind end of described heater is provided with the fixing device 1 for being used for fixing heater.
Described fixing device 1 is double faced adhesive tape, and the stickup of double faced adhesive tape is more firm, and material is the common thing of daily life
Product, easily obtain.
Described packaging bag 6 is provided with the strip of paper used for sealing 6-1 for being easy to Kaifeng, and packaging bag 6 can be thrown off by opening strip of paper used for sealing 6-1.
