Laparoscope lens flushing device and flushing method thereof

Abstract

The invention relates to a laparoscope lens flushing device and a flushing method thereof. The laparoscope lens flushing device comprises a pipe sleeve, a flushing assembly and a control unit, the pipe sleeve is used for assembling a laparoscope lens, the flushing assembly is used for flushing the laparoscope lens, the control unit can acquire image information of the laparoscope lens in real time, and use a support vector machine algorithm or image processing algorithms such as a neural network to determine the pollution condition of the laparoscopic lens, the washing assembly can be autonomously controlled to wash the laparoscope lens on the basis of the pollution condition, updated in real time, of the laparoscope lens, automation and intellectualization of flushing operation are achieved, prior operation training is not required for the use of the laparoscope lens flushing device, and participation of doctors is not needed in the washing process, so that doctors can focus on the operation conveniently.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laparoscopic lens washing device and a washing method thereof. Background technique [0002] Laparoscopic technology is the premise of minimally invasive surgical technology. It is not only widely used in routine operations such as appendicitis and inguinal hernia, but has also been widely used in colorectal cancer and gastric cancer after repeated verification of its safety in a large number of high-quality clinical studies. In surgical treatment, it has become an indispensable work platform for gastrointestinal surgeons, and it is also one of the core standards for measuring the level of general surgery in a medical unit. [0003] In the actual surgical operation, the laparoscopic lens is used as the visual field guide for all members of the surgical team, ensuring its clarity and stability is directly related to the safety of the operation and whether it goes smoothly or n...

Problems solved by technology

This method cannot guarantee the cleaning quality, and at the same time, there is a greater safety risk

[0004] Aiming at the cleaning problem of laparoscope lens, in the prior art, attempts have been made to design new laparoscope structure and add anti-fog coating, etc., but all of them cannot be used in large-scale clinical application due to poor effect and high cost

For example, some existing patents propose new laparoscopic structures, such as patent CN201410244729.3, which relates to a self-cleaning and inclination adjustment transmission mechanism for intra-abdominal vision robot units; patent CN201810408619.0, which relates to a laparoscopic cavity The inner lens cleans the trocar; but these two structures are relatively complicated, and there are many modifications to the laparoscope. Wiping with gauze and other methods not only limits the number of times of use, but may also cause hidden dangers left by the gauze

Patent CN201910017184.5 relates to a washing and drying device for the lens of a cavity mirror, which can directly realize the washing of the lens in the body cavity, but the design of the device involves the modification of the existing standard cavity mirror, and the modification range is relatively large, and it cannot general purpose, limited scope

Moreover, most of the above laparoscopic lens washing devices are semi-automatic washing devices, which require the participation of doctors to complete the washing of laparoscopic lenses, that is, doctors are required to participate in the cleaning operation

However, in the actual operation process, the doctor needs to be highly concentrated. The doctor needs to observe the state of the patient's body and also needs to distract his attention to complete the cleaning operation of the laparoscopic lens, which increases the difficulty of the doctor's operation, that is, Said that the cleaning operation of the existing laparoscopic lens washing device needs to rely on the participation of doctors, and cannot realize automatic and intelligent cleaning

[0005] Generally speaking, the existing laparoscopic lens flushing device has a complex structure, poor decontamination effect, and requires modification of the existing standard laparoscope before it can be used, which is inconvenient to use and has potential safety hazards. In addition, most of them are semi-automatic flushing The device needs to rely on doctors to participate in the cleaning operation, and cannot realize automatic and intelligent cleaning
