Description

Heating and demisting device for laparoscope

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to peritoneoscope heating defogging device.

Background

Laparoscope is similar to electronic gastroscope, and laparoscopic surgery is a newly developed minimally invasive method and is an inevitable trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities.

In particular, a laparoscope is an instrument with a miniature camera. Laparoscopic surgery is a procedure performed using a laparoscope and its associated instruments: the cold light source is used for providing illumination, the laparoscope lens (the diameter is 3-10 mm) is inserted into the abdominal cavity, the digital camera technology is used for leading the image shot by the laparoscope lens to be transmitted to a post-stage signal processing system through an optical fiber, and the image is displayed on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument. Namely, laparoscopic surgery is to make several small incisions with a diameter of 5 to 12 mm at different parts of the abdomen, insert a camera lens and various special surgical instruments through the small incisions, transmit images of various organs in the abdominal cavity shot by a camera inserted into the abdominal cavity to a television screen, and complete the surgery by observing the images and using various surgical instruments to operate in vitro.

The novel laparoscopic surgery is a surgery completed by advanced equipment principles such as electronics, optics and the like in modern high-tech medical technology, is an epoch-crossing progress of the traditional laparotomy, and is a surgery performed in a closed abdominal cavity: the camera system is under the illumination of good cold light source, through being connected to the peritoneoscope body in the abdominal cavity, take a photograph of the internal organs in the abdominal cavity on the monitor screen, and the operation doctor is under the supervision of hi-Tech display screen, guide, operates surgical instruments outside the abdominal cavity, explores, congeals, stanchs, tissue separation and incision, sews up the operation such as. The endoscope is a model of the application of high-tech technologies such as electronics, optics, camera shooting and the like in clinical operations, has the characteristics of small wound, few complications, safety and quick recovery, can be quickly developed in surgical endoscopic operations in recent years, can be used for simultaneous examination and treatment, and is the most advanced and most advanced minimally invasive technology at present. The role in the treatment of surgical disorders has become more and more attractive. And is internationally and exuberantly developed.

As described above, in laparoscopic surgery, a laparoscopic lens having a camera mounted thereon corresponds to an "eye" of an operator, and a doctor enters an abdominal cavity through one puncture hole to observe the abdominal cavity of a patient in all directions. However, during surgery, the laparoscope lens is always covered by a layer of mist. That is because the temperature of peritoneoscope camera lens will be less than the temperature in the human abdominal cavity, and after the camera lens got into the abdominal cavity, there is the difference in temperature between abdominal cavity and the camera lens to make the steam in the abdominal cavity form the fog on the camera lens surface very fast, thereby lead to the camera lens to become fuzzy, and then influence the normal clear of operation, can lead to the operation failure even.

For this situation, there are three common methods for defogging the laparoscope lens:

first, a conventional preheating method. Before the operation is started, a nurse puts the laparoscope lens into sterile physiological saline with the temperature of about 60-80 ℃ to preheat for about 5min, when the lens reaches the temperature of a body cavity, the lens is quickly put into the abdominal cavity, and when the temperature of the lens is higher than that of the abdominal cavity, water vapor can not be liquefied on the surface of the lens and form mist to influence the sight. However, during the operation, the hot saline in the container needs to be replaced at any time according to the water temperature condition. Like this, not only prepare, preheating time overlength, waste time and energy, medical staff need be carefully scalded by hot salt solution constantly when using in addition, also need very carefully when moving, prevent that hot salt solution from spilling out and polluting the operating table, and is very inconvenient, simultaneously, if hot salt solution temperature is too high, can show the life-span that shortens the peritoneoscope camera lens to cause equipment to accelerate the damage, aggravate disease medical burden.

Second, an anti-fog and oil-fog method. Before the lens of the laparoscope enters the abdominal cavity, a little antifogging oil is firstly extracted by a sterilizing injector, then the antifogging oil is directly dripped on the top end of the lens or is dripped on a cotton ball, and then the antifogging oil is uniformly smeared on the top end of the lens of the laparoscope to prevent fogging. The antifogging oil can form a monomolecular transparent film on the surface of the lens, and the transparent film can prevent water vapor from condensing into water drops. However, most of antifogging oil for endoscopes in the current market is imported abroad and is expensive, so that the burden of patients is increased. Moreover, the antifogging oil needs to be repeatedly wiped in the using process, so that the probability of pollution and lens damage is increased.

And thirdly, an iodophor wiping anti-fog method. The front end of the lens is wiped by an iodophor cotton ball before the lens is placed in the abdominal cavity, and then redundant iodophors are wiped by a dry cotton ball. The iodophor is an amorphous compound containing iodine, has smooth properties, can form a protective film on the surface of the lens, and can isolate hot air in the abdominal cavity from being attached to the lens to play a role in preventing fog. This method has the following disadvantages: the antifogging effect is better within 30min, but the effect is not good after 30min, and when the operation time is longer, antifogging measures are still required to be carried out again or repeatedly. In the operation process, if the sight is found to be fuzzy, when defogging is required again, the lens is wiped by using wet gauze, then the iodophor cotton ball is wiped, and then the redundant iodophor is wiped by using dry gauze, so that the judgment of the color of the visceral organs in the abdominal cavity of the patient by medical staff is not influenced. In addition, patients who are allergic to iodine cannot use this method. Therefore, this method also has various inconveniences and disadvantages.

In summary, there is a need for a device for defogging laparoscope lenses more conveniently, safely, quickly, cheaply and effectively during laparoscopic surgery.
