Description
Technical Field
The invention relates to the field of medical auxiliary instruments, in particular to a liquid-containing coating, a protective sleeve and a preparation method thereof.
Background
The endoscopic minimally invasive surgery is characterized in that an image of a surgical part is shot in real time through an endoscopic lens, the image is transmitted to a display screen, a surgeon can see the display screen to analyze and judge the actual condition of the focus part, and a tiny instrument is utilized to implement local surgery. The endoscope is used as the eyes of an operator, and the observation mode in the operation process is changed from original direct visual observation into endoscopic observation, so that the maintenance of the clearness of the endoscope lens is very important for smoothly completing the endoscopic operation. However, the endoscope operation is often interrupted due to the contamination or fogging of the mirror surface, the operation is continued after the mirror surface is cleaned, the interruption breaks the continuity of the operation, especially when the lens is fogged or contaminated during the operation, the operating doctor cannot see the operation part clearly, the operation process is seriously affected, the operation time is prolonged, the energy and physical exertion of the operating doctor are increased, and even additional damage is caused to the patient.
In actual operation, the fogging and the pollution of the lens need to be treated by taking measures respectively. Such as: in the enteroscopy operation, an effective removing mode for smoke generated when the operation electrotome cuts off diseased tissues does not exist, and the operation can be performed only after the smoke is automatically dissipated; and blood, protein, tissue debris and other pollutants adhered to the lens are removed by a surgeon in a water-jet flushing mode. For another example: in laparoscopic surgery, a certain amount of air is introduced into the abdominal cavity to form pneumoperitoneum before the surgery, so that the temperature difference is formed between the metal endoscope and a human body, and the phenomenon of lens fogging is more serious and frequent; when the lens is fogged, the endoscope is placed into hot saline for preheating, and is quickly placed into the body of a patient after being preheated in advance, so that the lens is prevented from being fogged; however, the metal laparoscope has fast heat conduction, the method can only temporarily maintain the lens to be clear, and the laparoscope still needs to be repeatedly taken out of the body and preheated again in the operation process; when the lens is polluted by blood, tissue fluid and the like in the laparoscopic surgery, the lens is taken out and cleaned in vitro. In clinical operation, take out repeatedly, put into the chamber mirror and can seriously influence the operation process, increase the operation risk even, recycle simultaneously and assist article clearance camera lens also can increase the sore infection probability.
To the above-mentioned problem of need taking out the camera lens from the body repeatedly, a variety of solutions have been disclosed in the prior art, such as: chinese patent document CN 208065285U discloses a method for cleaning a lens by adding a cleaning system similar to a wiper of an automobile; chinese patent document CN 205514519U discloses that a group of air tubes are installed around the endoscope, and the lens is continuously heated and contaminants adhered to the lens are purged by blowing hot air; chinese patent document CN 205597889U discloses that a layer of electrothermal film is adhered to the body of a cavity mirror, and the lens is heated by electrothermal means to prevent fogging. Although the structures solve the problem that part of the lens needs to be taken out of the body repeatedly, the schemes introduce more complex structures into the cavity mirror, so that the volume of the cavity mirror is increased, and dead angles of disinfection and cleaning are increased; moreover, the auxiliary units are high in modification cost, and the interior, interlayer and the like of the existing laparoscope need to be modified in all directions, so that the auxiliary units are difficult to popularize and utilize.

The central axis of the sleeve body is perpendicular to the plane where the liquid-containing coating is located.
The liquid film coating comprises a liquid film, a substrate layer and a transparent support piece, wherein the liquid film is arranged on the substrate layer, and the side, deviating from the liquid film, of the substrate layer in the liquid-containing coating is arranged on the transparent support piece.

and forming a base material layer with a laminated structure by adopting a base material, and pouring a protective solution on the base material layer until the base material layer is saturated and a liquid film is formed on the base material layer.
The technical scheme of the invention has the following advantages:
1. the invention discloses a liquid-containing coating, which specifically comprises a substrate layer and a liquid film, wherein the substrate layer is adsorbed or/and swelled with a protective liquid, the protective liquid is in a liquid state, and the liquid film with low surface energy is formed on the surface of the substrate layer. Because the liquid film has low surface energy, the water vapor condensation and the blood stain adhesion can be prevented; the liquid-containing coating is of a layered structure and can be effectively attached to the lens of the cavity mirror without changing the structure of the lens of the cavity mirror. Therefore, after the liquid-containing coating is arranged on the lens of the cavity mirror, the effects of avoiding the fogging and the pollution of the lens can be achieved under the condition of not changing the structure of the lens of the cavity mirror, and the effects are very obvious.
2. Because in the process of using the endoscope, the lens needs to continuously move in the body, so that the friction between the lens and the inner wall of the stomach and intestine in the body is very frequent, if a conventional coating is adopted to protect the lens, the damage of the coating is very easily caused in the friction process, and the service life of the coating is greatly reduced. According to the invention, by optimizing the structural arrangement of the substrate layer, the method specifically comprises the following steps: the base material layer is made of organic silicon high polymer capable of swelling the protective solution; or a porous structure capable of adsorbing the protective liquid is arranged, the porosity of the porous structure is not lower than 80%, and the pores are continuous through holes which are communicated with each other in a penetrating way; through the arrangement, when the liquid-containing coating is applied to the lens of the endoscope, the substrate layer can play a role in storing and locking the protection liquid, so that the protection liquid is supplemented to the worn part in time to form a new liquid film, and the purpose of prolonging the service life is effectively achieved. Specifically, when the substrate layer is made of the organic silicon polymer, the protection liquid is swelled in the organic silicon polymer, and the organic silicon polymer is matched with the protection liquid, so that after a liquid film on the surface layer of the organic silicon polymer is worn, the liquid film at the worn part can be supplemented by the protection liquid swelled in the organic silicon polymer in time, a new liquid film is formed, and the anti-fog and anti-fouling duration is effectively prolonged. When the substrate layer is formed by adopting a porous structure, the protection liquid is adsorbed in pores of the porous structure, when the liquid film on the surface of the liquid-containing coating is lost due to factors such as friction and the like, the protection liquid at the non-worn part can flow to the worn part through the continuous through holes which are mutually communicated in a penetrating way, so that the purpose that the substrate layer spontaneously supplies the supplementary protection liquid to the worn part to promote the formation of a new liquid film is achieved, and the service life is effectively prolonged.
3. According to the invention, through the optimized arrangement of the porous structure and the material, the purpose of reducing the loss of the protection liquid can be achieved; specifically, the porous organic silicon film is directly prepared from the organic silicon high polymer, and when the substrate layer is prepared from the porous organic silicon film, the substrate layer can have the functions of swelling and adsorbing the protective solution. After the substrate layer is prepared by adopting the porous organic silicon film and is swelled and adsorbs the protective liquid, the thickness of a liquid film formed on the surface of the substrate layer can be obviously reduced, and meanwhile, the detection proves that after the anti-fog and anti-fouling effectiveness is verified for 48 hours, the loss of the thickness of the liquid film is minimum, and the effect is very obvious.
4. The invention provides a specific structure of a protective sleeve, which is provided with a sleeve body, a fixing device and a liquid-containing coating, wherein the protective sleeve can be effectively fixed at the tail end of a cavity mirror through the matching of the sleeve body and the fixing device, and the liquid-containing coating is arranged at an opening at one end of the sleeve body.
