Description

Integrated adjustable laparoscopic surgery smoke discharging and abdominal cavity liquid sucking device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an integrated adjustable laparoscopic surgery smoke evacuation and abdominal cavity liquid suction device.

Background

Laparoscopic surgery is a newly developed minimally invasive method and is a necessary 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. The traditional method of the retrolaparoendoscopic surgery is to make three small 1 cm incisions on the waist of a patient, insert a tubular working channel called trocar respectively, and carry out all the following operations through the three channels; and then special lengthened surgical instruments are used for completing the same steps as the open surgery under the television monitoring, so that the same surgical effect is achieved.

However, there are some disadvantages of the existing laparoscopic surgery, first the abstract of the original text of CN 112190324 a: in the process of laparoscopic surgery, a large amount of smoke generated by electric surgical equipment such as an ultrasonic knife and a high-frequency electrotome easily influences the surgical field of vision, so that video development is blurred, and further, the surgical risk is increased. In addition to the effects of smoke itself outside the surgical field of view, high concentrations of smoke can also easily condense on the laparoscopic lens. In operation, an assistant often needs to open the air hole of the trocar intermittently to exhaust smoke or suck the smoke out by using an aspirator; on the other hand, the assistant hand also needs to take out the lens frequently and wipe the lens with iodophor gauze. The smoke contains harmful substances such as CO, acrylonitrile, hydrogen cyanide, formaldehyde, benzene, living viruses and the like, and is directly discharged into an operating room to seriously pollute the air of the operating room. There are several reports that operating room smoke can also cause operating room personnel to become infected with viruses or bacteria. The automatic smoke discharging type cavity mirror equipment in the market is not popularized due to the purchase and use cost and the like. In the prior art, such as CN201721024116.4, smoke is automatically exhausted by using a smoke sensing device, although the above problems can be solved, the gas can not be exhausted at any time during laparoscopic surgery, for example, in cases of narrow surgical field, free large blood vessels, etc., collapse of the gas cavity caused by exhausting and exhausting smoke can seriously affect the surgical operation and even endanger the life of the patient. In the prior art, such as CN201811480418.1 and CN201720065185.3, an image analysis system is used to automatically discharge smoke, which can solve the above problems, but the technology is complex, and the device is not always compatible with different brands of laparoscopic devices, and is difficult to be popularized clinically. The problems that the smoke interferes with the operation visual field and pollutes the environment of an operating room in the laparoscopic operation are not conveniently solved, and therefore the integrated adjustable laparoscopic operation smoke exhausting and abdominal cavity liquid sucking device is provided.
