In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

With the rapid advance of industrial manufacturing technology, the endoscope operation is a necessary trend of future operation development, and the endoscope is used for examination and treatment in the abdominal cavity, can directly and clearly observe the conditions in the abdominal cavity of a patient, and can perform operation treatment on abnormal conditions. However, during the operation, the endoscopic lens is easily contaminated by smoke generated by tissues or equipment in the body, so the operation has to be temporarily interrupted, the endoscope is taken out, and the lens is cleaned. At present, most of the cleaning operations of the endoscope lens are manually completed, and the specific process is to take the endoscope out, clean the lens, wipe the lens and then place the lens in the abdominal cavity for continuous operation. Such cleaning methods not only can waste operation time and reduce operation efficiency, but also can increase operation cost by being equipped with special personnel cleaning lenses, and the cleaning effect is often unsatisfactory, the problem of residual water stain cannot be thoroughly solved, and the cleaning effect cannot meet the actual use requirement. And in the current chamber mirror washing mode, the washing liquid is provided for the washing equipment mainly by manual extrusion, for example, the washing liquid is provided with power by pressing a pressure bag or pushing an injector, the washing liquid can not reach the washing pressure required actually, the stain on the chamber mirror lens can not be thoroughly removed, and after washing, the water stain can be left on the chamber mirror lens, the definition of the chamber mirror lens can still be influenced, and the smooth operation of the operation is further influenced.

In order to solve the problems, the invention provides a method and equipment for washing an endoscope. In the using process, the cleaning solution is provided by implementing the washing step, so that the washing piece can wash the endoscope in the operation process; and then, blowing gas is provided through the blowing step, so that the flushing piece can blow residual water stains on the endoscope in the operation process. Thereby avoided the manual cleaning chamber mirror to lead to wasing thoroughly and influence the problem of operation progress to solve extravagant operation time, increased operation cost scheduling problem.

The endoscope flushing method and the flushing device provided by the invention are described in detail below with reference to the attached drawings.

Referring to fig. 1, fig. 1 is a flow chart of a laparoscopic flushing method comprising: a flushing step and a blowing-off step. In this embodiment, the flushing step may be performed first and then the purging step may be performed. Specifically, the endoscopic washing method comprises the following steps:

s110, a washing step: and introducing a cleaning fluid into the flushing part so that the flushing part flushes the cavity mirror.

In this step, the manner of introducing the cleaning liquid into the flushing member may be to increase the pressure of the cleaning liquid storage device to press out the cleaning liquid, or to press out the cleaning liquid in other manners, which is not specifically limited herein. In this step, the flushing process may be continuous flushing or pulse flushing. For example, in some embodiments, the rinsing fluid is continuously introduced into the rinsing member to continuously rinse the cavity mirror through the rinsing member, and in other embodiments, the rinsing fluid is introduced into the rinsing member in a pulsed manner, for example, the rinsing fluid is introduced into the rinsing member for a period of t2 at intervals of t1, so that the rinsing member pulses the cavity mirror. After the endoscope is subjected to the washing step, the in-vivo tissues, blood and the like on the endoscope or smoke generated by equipment in the operation process can be washed clean.

S120, a blowing-off step: blowing clean gas into the flushing piece so that the flushing piece blows air to the cavity mirror.

In general, although the cavity mirror achieves the cleaning effect after the washing step, a small amount of cleaning liquid may be remained on the lens, and the cleaning liquid may form water stains on the lens. Blow-off gas is introduced into the flushing piece, so that the flushing piece blows air to the endoscope. Similarly to step S110, the air blowing process may be continuous air blowing or pulse air blowing. For example, in some embodiments, purging gas is continuously supplied to the flushing member to continuously insufflate the cavity mirror through the flushing member, and in other embodiments, purging gas is supplied to the flushing member in pulses, for example, for a period of t4 at intervals of t3, so that the flushing member insufflates the cavity mirror. Residual water stain on the lens can be avoided after the blowing-cleaning step, and the effect of thoroughly cleaning the cavity mirror is achieved. And the steps of suspending the operation, taking out the endoscope and the like are not needed in the whole flushing process, so that the operation time and the cost of cleaning equipment in the operation process are saved.

In a specific embodiment, the endoscopic irrigation method comprises: in the washing process, the washing step and the blowing-off step can be alternately carried out according to actual needs, and the endoscope lens can be timely and quickly washed clean, so that the endoscope lens can be always kept clean and tidy in the whole operation process, and the cleaning effect is improved.

The flushing device 12 and the blowing-out device 13 of the cavity mirror flushing device 1 are supplied with pressure gas through a pressure gas input port 17. The pressure gas input port 17 is also provided with a device having a pressure reducing function, such as a control device shown in fig. 4. Since the pressure of the gas input by the pressure gas input port is large and cannot be directly used, the pressure of the gas needs to be reduced from high pressure to lower pressure before the gas is input into the flushing device 12 and the blowing-out device 13. The device having the pressure reducing function may be configured such that a pressure reducing device 21 as shown in fig. 4 is provided at the pressure gas input port 17 to reduce the pressure of the gas to a pressure suitable for use.

As shown in fig. 3, one end of the first branch gas pipe 174 is connected to the main gas pipe 173, and the other end is connected to the cleaning solution containing part 121, so that the pressure gas transmitted from the main gas pipe 173 is transmitted to the cleaning solution containing part 121 to pressurize the interior of the cleaning solution containing part 121. The cleaning liquid in the cleaning liquid containing part 121 can be pressed out by pressurizing the inside of the cleaning liquid containing part 121 and then opening the first control switch 14, and the cleaning liquid can reach the actually required pressure to wash the stains on the surface of the endoscope lens by adjusting the pressure in the cleaning liquid containing part 121.

With continued reference to FIG. 4, a second branch air delivery conduit 175 has one end connected to the other end of the main air delivery conduit 173 and the other end connected to the buffer chamber 131; the input of pressurized gas into the buffer chamber 131 through the pressurized gas input port 17 facilitates buffering the pressurized gas and increasing the pressure of the purge gas in the buffer chamber 131.

The intensity of the cleaning liquid discharged from the cleaning member 11 depends on the CO in the cleaning liquid container 121 ₂ And the pressure is controlled by a corresponding switch in the control switch group 18, and the control mode may be PWM control, open duration control, pressure value integral control, and the like. The pressure in the cleaning liquid accommodating part 121 can be adjusted within a range from 0bar to Nbar, wherein the larger the water pressure is, the stronger the washing capacity of the endoscope lens is, but the comprehensive safety and the body feeling comfort of a patient are, and the pressure is set to be 0.5bar-1.5bar. Another path of reduced CO ₂ Enters the buffer chamber 131 after passing through the corresponding switch in the control switch group 18, and CO with a certain volume and a certain pressure intensity is stored in the buffer chamber 131 ₂ The gas, controlled by the operator, opens the second control switch 15, and CO is in the buffer chamber 131 ₂ And (4) gas is sprayed out. CO sprayed from the flushing member 11 ₂ Is dependent on the CO in the buffer chamber 131 ₂ Pressure of (2), CO in the buffer chamber 131 ₂ Is controlled by a corresponding switch in the control switch bank 18. The pressure in the buffer chamber 131 can be adjusted in the range of 0bar to Nbar, and the higher the air pressure is, the stronger the cleaning capability of water stains on the lens is, but the pressure is set to 0.5bar-1bar for safety and patient comfort. The function of the pressure detection means 16 is to monitor the pressure in the abdominal cavity of the patient, and if the pressure in the abdominal cavity of the patient is higher than a certain pressure, for example higher than 20mmHg, the apparatus prohibits the controlled opening of the second control switch 15, ensuring the safety of the patient. The air injection function can be started only when the abdominal cavity pressure of the patient is lower than the safe air pressure. At the second control switch 15In an open state, that is, when the device is in the process of injecting air, the pressure detection device 16 monitors the abdominal cavity pressure of the patient in real time, when the pressure is higher than a certain pressure, for example, 30mmHg, the second control switch 15 is immediately closed to stop injecting air, and if necessary, the abdominal cavity of the patient can be rapidly reduced through other external pressure reduction devices.
