Description
Technical Field
The invention relates to articles for daily use for human beings, in particular to medical equipment, in particular to a laparoscope, and specifically relates to an antifogging method and an antifogging device for a laparoscope lens.
Background
Laparoscopic surgery has the advantages of small trauma, quick postoperative recovery, and the like, and is widely used in surgical operations at present. The clear surgical field is a precondition for ensuring the surgical quality, and can shorten the surgical time and reduce the injury in the surgery. However, in laparoscopic surgery, due to the temperature difference between the lens temperature and the temperature in the abdominal cavity, the lens fogging phenomenon is easily caused. Lens fogging can affect the operator's field of vision, extend the procedure time, and increase the risk of surgery. Therefore, the anti-fog technology of the laparoscopic lens in laparoscopic surgery is a key to ensure the surgical quality.
The reason of lens fogging is mainly related to the temperature difference between the environment in the abdominal cavity of a human body and the operating room, and because the temperature of the laparoscope is lower than that of the environment in the abdominal cavity, water vapor is condensed before the lens, so that the lens fogging is caused. Due to the sterility requirement of laparoscopic procedures, the prior art of heating anti-fog is preheated by hot saline to approach the temperature in the abdominal cavity. However, the heating part of the hot brine soaking method is only positioned at the front end of the lens and the local temperature is higher, so that the heating effect is short, the lens is easy to age, and the service life of the instrument is shortened.
How to solve the problem of atomization of a laparoscopic lens in laparoscopic surgery, a lot of solutions exist in the current academic world, however, the solutions are not good or the cost is high. The anti-fog problem of the laparoscopic lens increases the difficulty of laparoscopic surgery and prevents the laparoscopic surgery from being popularized in the vast primary hospitals.
The main difficulty in solving the laparoscopic fogging phenomenon is that it is difficult to heat the laparoscopic lens by means of external equipment in a sterile surgical environment.
Disclosure of Invention
The invention aims to provide a laparoscope lens antifogging method which aims to solve the technical problem that a laparoscope lens in the prior art is poor in antifogging effect in laparoscopic surgery.
The invention relates to a method for preventing fog of a laparoscope lens, which comprises a process of heating the laparoscope lens body, wherein in the process of heating the laparoscope lens body, a thermochromic rubber pad is used for repeatedly rubbing the outer side surface of the laparoscope lens body, the laparoscope lens body is heated by heat generated by friction, when the thermochromic rubber pad prompts that the temperature reaches 60 ℃ in a color changing mode, the heating is finished, and the lens of the laparoscope is also heated simultaneously by a heat transfer principle, so that the effect of preventing fog of the lens of the laparoscope is achieved.
The invention also provides a laparoscope lens antifogging device, which comprises a laparoscope, wherein the laparoscope comprises a lens, a lens body and a handle, the lens is arranged at the front end of the lens body, and the lens body is connected with the handle, and the antifogging device is characterized in that: the outer side of the mirror body is provided with a rubber pad, a thermochromic additive is distributed in the rubber pad, one side of the rubber pad is provided with an arc-shaped groove, and the arc-shaped groove is matched with the outer side of the mirror body.
Further, the rubber pad is cuboid.
Further, the arc-shaped groove is semi-cylindrical.
The invention is provided with a rubber pad formed by medical silicone rubber containing thermochromic additives at the outer side of the laparoscopic body, a groove is formed in the rubber pad, the groove is wrapped at the outer side of the laparoscopic body, and the rubber pad is repeatedly moved along the length direction of the laparoscopic body, so that the rubber pad and the laparoscopic body are in a sliding friction state, the whole temperature of the laparoscopic body is gradually increased, and then heat is transferred to a lens, thereby playing an anti-fog effect.
The medical silicon rubber material made of the doped thermochromic material is used for manufacturing an elastic thermochromic rubber pad, and the color of the rubber pad can be changed when the local temperature of the rubber pad is higher than 60 ℃ due to the addition of the thermochromic material. The rubber pad can be used on a sterile operating table after being sterilized. Solves the problem that the laparoscopic lens is difficult to heat in a sterile operation environment.
The specific using method is as follows: in laparoscopic surgery, before the laparoscopic lens enters the abdominal cavity, one hand holds the laparoscopic handle, the other hand bends and wraps the thermochromic rubber pad on the laparoscopic lens body, and about 15kg of holding force is applied, meanwhile, the rubber pad is repeatedly moved to achieve the state that the rubber pad and the laparoscopic lens body are in sliding friction, after about 20 seconds, the overall temperature of the laparoscopic lens body is gradually increased due to repeated friction with the rubber pad to generate heat, and when the laparoscopic lens body is heated to about 60 ℃, the rubber pad changes color to prompt the heating to be completed. At this time, due to the heat transfer principle, the whole temperature of the laparoscope lens is higher than the environment temperature in the abdominal cavity of a patient, and the lens is placed into the abdominal cavity at this time, so that water vapor cannot be condensed before the lens, and the anti-fog effect is achieved.
Compared with the prior art, the invention has the technical effects of being positive and obvious. According to the invention, the friction heating principle is utilized, the rubber pad made of the medical thermochromic material is utilized to rub the laparoscopic lens body, the laparoscopic lens body is heated to more than 60 ℃, the rubber pad changes color to be used as an indication, and due to the heat transfer principle, the laparoscopic lens is precisely heated to the temperature for avoiding condensation of water vapor in the abdominal cavity before the lens, so that the anti-fog effect of the lens is achieved, and the anti-fog laparoscopic lens has the characteristics of simplicity, rapidness, economy and practicability.
