Description

Laparoscopic lens flushing device and flushing method thereof

technical field

The invention relates to the field of medical instruments, in particular to a laparoscopic lens flushing device and a flushing method thereof.

Background technique

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. It has become an indispensable work platform for gastrointestinal surgeons and one of the core standards for measuring the general surgery level of a medical unit.

In the actual operation, the laparoscopic lens serves as the field of vision guide for all members of the operation group, and ensuring its clarity and stability is directly related to the safety of the operation and the smooth progress of the operation. However, during the operation, it is inevitable that the lens will be contaminated due to the temperature difference inside and outside the abdominal cavity and the splash of blood-stained lipid droplets. The operation needs to be interrupted immediately for cleaning. At present, the laparoscopic lens is withdrawn from the abdominal cavity and cleaned and wiped outside the patient's body. However, temporary interruption of the operation will prolong the operation time, and at the same time, doctors cannot observe the patient's abdominal cavity in time, let alone perform key operations such as hemostasis, which poses a huge safety hazard. In the prior art, some of the mirror-holding hands adopt the tissue wiping method, that is, use the greater omentum and the surface of the liver in the abdominal cavity to wipe the lens. This method cannot guarantee the quality of cleaning, and at the same time, there is a large safety risk.

In view of the cleaning problem of laparoscopic lenses, methods such as designing new laparoscopic structures and adding anti-fog coatings have been tried in the prior art, but they cannot be applied in large-scale clinical applications 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 tilt angle adjustment transmission mechanism for an intra-abdominal vision robot unit; patent CN201810408619.0 relates to a laparoscopic cavity The inner lens is used to clean the trocar; however, these two structures are relatively complex, and there are many modifications to the laparoscope. Wiping with gauze and other methods not only limits the number of uses, but also may cause hidden dangers left by gauze. Patent CN201910017184.5 relates to a rinsing and drying device for a cavity mirror lens, which can directly flush the lens in the body cavity. However, the design of the device involves the transformation of the existing standard cavity mirror, and the scope of transformation is large, and it cannot be used. General, small scope of application.

Generally speaking, the existing laparoscopic lens has a complex structure, and the cleaning effect is not good, and the existing standard laparoscopic lens needs to be transformed before it can be used, which is inconvenient to use and has potential safety hazards.
