Description
Technical field
The utility model relates to mankind life article more particularly to medical instrument, in particular to laparoscope, particularly one
Kind lens of laparoscope anti-smog device.
Background technique
Laparoscopic surgery has many advantages, such as that wound is small, post-operative recovery is fast, is widely used in surgical operation at present.Clearly
Surgical field of view is to guarantee the premise of surgical quality, can shorten operating time, reduces and damages in art.However in laparoscopic surgery,
Due to the temperature difference of camera lens temperature and intraperitoneal temperature, camera lens atomizating phenomenon is easily led to.Camera lens atomization will affect the patient visual field, extend
Operating time increases operation risk.Therefore, the antifog technology of lens of laparoscope is to guarantee the pass of surgical quality in laparoscopic surgery
Key.
Mainly and in human abdominal cavity environment is related with there are temperature differences in operating room for the reason of camera lens hazes, due to laparoscope
Temperature be lower than intraperitoneal environment, vapor agglomerates to the cold before camera lens, and camera lens is caused to haze.It is sterile due to laparoscopic procedure
It is required that the existing antifog technology of heating is impregnated with hot salt brine and preheated, it is allowed to close with intraperitoneal temperature.However hot salt brine infusion method adds
Hot spot is only located at camera lens front end and local temperature is higher, and not only heating effect is of short duration but also easily makes camera lens aging, shortens instrument
Service life.
How the atomizating phenomenon of in laparoscopic surgery lens of laparoscope is solved, the scheme of academic circles at present has very much, however
Most effect is bad or higher cost.The antifog problem of lens of laparoscope increases the difficulty of laparoscopic surgery, hinders abdomen
Endoscope-assistant surgery is promoted in vast basic hospital.
The main difficulty for solving laparoscope atomizating phenomenon is to be difficult to heat by external equipment in sterile surgical environments
Caused by lens of laparoscope.
Utility model content
The purpose of this utility model is to provide a kind of lens of laparoscope anti-smog device, this lens of laparoscope is anti-
Mist device will solve the bad technical problem of lens of laparoscope in the prior art elimination fog effect in laparoscopic surgery.
The utility model provides a kind of lens of laparoscope anti-smog device, including a laparoscope, the laparoscope packet
Camera lens, shank and handle are included, the front end of the shank is arranged in the camera lens, and the shank and the handle connect
It connects, it is characterised in that: be provided with a rubber pad on the outside of the shank, thermo-color addition is distributed in the rubber pad
Agent, the side of rubber pad are provided with an arc groove, the arc groove with and shank on the outside of be equipped with.
Further, the rubber pad is cuboid.
Further, the arc groove is semicolumn figure.
The utility model is provided with a medical silicon rubber by becoming colour additive containing heat on the outside of the shank of laparoscope
The rubber pad that glue is constituted has a groove in the rubber pad, the groove is wrapped in the outside of laparoscope shank,
Rubber pad is moved repeatedly along the length direction of laparoscope shank, reaches rubber pad and laparoscope shank is in sliding friction state,
Laparoscope shank bulk temperature is gradually risen, camera lens is then transferred heat to, to play antifog effect.
The utility model makes one piece of flexible thermal change using medical grade silicon rubber material made of doping thermochromatic material
Color rubber pad, the rubber pad make the rubber pad that can change material face when local temperature is higher than 60 DEG C since off-color material is added
Color.The rubber pad can use after disinfection on aseptic operation table.Solves the laparoscope mirror in sterile surgical environments
The difficult problem of head heating.
Specifically used method is: in laparoscopic surgery, before lens of laparoscope enters abdominal cavity, one is held tight laparoscope
Thermo-color rubber pad is bent the grip for being wrapped in laparoscope shank, and applying 15kg or so by handle, another hand, while repeatedly
Mobile rubber pad reaches rubber pad and laparoscope shank in sliding friction state, and after about 20 seconds, shank is due to anti-with rubber pad
Multiple frictional heat generation, bulk temperature gradually rises, and when shank is heated to 60 DEG C or so, rubber pad changes color tips and heated
At.At this point, lens of laparoscope bulk temperature is higher than environment temperature in abdominal cavity of patients, and camera lens is at this time due to the principle of heat transfer
Merging abdominal cavity not will lead to vapor and agglomerate to the cold before camera lens, achieve the effect that antifog.
The utility model is compared with prior art, its technical effect is that actively and apparent.The utility model utilizes friction
In the way of rubber pad and the friction of laparoscope shank made of the medical thermochromatic material, laparoscope shank is added for heat principle
Heat is instruction with rubber pad discoloration, due to the principle of heat transfer, lens of laparoscope is accurately made to be heated to keep away to 60 DEG C or more
Exempt from the temperature that intraperitoneal vapor agglomerates to the cold before camera lens, to play the antifog effect of camera lens, there is simple, quick, warp
It helps practical feature.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of improved laparoscope of the utility model.
Fig. 2 is the schematic perspective view of one of the utility model thermo-color rubber pad.
Specific embodiment
Embodiment 1
As shown in Figure 1, the utility model provides a kind of lens of laparoscope anti-smog device, including a laparoscope, it is described
Laparoscope include camera lens 5, shank 1 and handle 2, the front end of the shank 1, the shank 1 is arranged in the camera lens 5
It is connected with the handle 2, the outside of the shank 1 is provided with a rubber pad 3, heat is distributed in the rubber pad 3
Change colour additive, and the side of rubber pad 3 is provided with an arc groove 4, the arc groove 4 with and the outside of shank 1 match
Close setting.
Further, the rubber pad 3 is cuboid.
Further, the arc groove 4 is semicolumn figure.
Specifically, the rubber pad 3 has elasticity and toughness, friction be not easy it is scaling-off, can significantly deformation, rubber pad 3 sets
It is equipped with drop-center 4, groove 4 is the semicolumn bodily form, and diameter can effectively increase rubber with common laparoscope shank diameter in friction
Effective contact area of rubber mat 3 and laparoscope shank 1.
As shown in Fig. 2, specific mode of operation are as follows: hold tight laparoscope handle 2 for one when use, another hand is by rubber
It pads groove 4 and is close to laparoscope shank 1, the grip that bending rubber pad 3 wraps laparoscope shank 1, and applies 15kg or so, simultaneously
It moves repeatedly rubber pad 3 and reaches rubber pad 3 and laparoscope shank head 1 in sliding friction state.After about 20 seconds, shank 1 due to
Frictional heat generation, shank bulk temperature gradually rise repeatedly with rubber pad 3, when shank is integrally heated to 60 DEG C or so, rubber
Pad 3, which changes color tips heating, to be completed.Due to the transfer principle of heat, camera lens 5 is also heated, and lens of laparoscope 5 is whole at this time
Temperature is higher than environment temperature in abdominal cavity of patients, and camera lens 5 is placed in abdominal cavity at this time and not will lead to vapor to be agglomerated to the cold before camera lens, reaches
To antifog effect.
