Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a gas perfusion and recirculation system with an attraction function.
Background
In minimally invasive surgery, because organs or other tissues of a human body are extruded together, and sufficient space observation and surgery are not available, the pneumoperitoneum machine is required to provide air pressure to prop open the abdominal cavity so as to provide a proper surgical space and surgical field, and the traditional pneumoperitoneum machine adopts a single-channel pipeline to intake air in a single direction at present to control the pneumoperitoneum establishment and abdominal cavity pressure detection so as to realize pneumoperitoneum control; the working principle of the pneumoperitoneum machine is similar to that of the pneumoperitoneum machine which is filled with 3 seconds of air and stops for 1 second to measure the intra-abdominal pressure, the working principle of the existing pneumoperitoneum machine determines that no brand pneumoperitoneum machine can be adjusted immediately, so that the peak value of the generated intra-abdominal pressure is higher than expected, the abdominal cavity pressure fluctuation is large, the operation space is unstable, and the operation space is large and small in time, so that the phenomenon similar to tide is generated. Further bringing about: the visual field is not clear enough, pneumoperitoneum is easy to lose, air pressure is unstable, the efficiency of an operating room is low, hypercapnia, acidosis, shoulder pain, low back pain, arterial and venous reflux pressure reduction, subcutaneous emphysema and other laparoscopic surgery problems.
In addition, in clinical medicine, when an electrotome in the puncture outfit cauterizes or electrocoagulates human tissues, a large amount of smoke and water vapor are inevitably generated, and when a deep operation of a human body is performed, particularly important organs such as deep blood vessels are electrocauterized, the smoke can obscure an electron microscope inside, the sight of medical personnel is influenced, the hemostasis is difficult, and even the operation is blind or busy, so that a smoke removal device is needed to ensure the smoothness of the operation.
Currently, the current situation of smoke removal in operating theatres:
1) The traditional method is to open an exhaust valve of the puncture cannula to directly remove smoke until the visual field is clear and then close a valve. Under the method, the smoke removal speed is influenced by abdominal pressure and the aperture of a smoke discharge valve, and the smoke discharge valve is a luer valve, so the aperture is small and the ventilation capacity is small, therefore, under the method, the smoke removal efficiency is extremely low, the continuity of the operation is influenced, and the smoke generated in the abdominal cavity contains various harmful substances and is directly discharged into an operation room, thereby causing the physical harm of operating room staff and the environmental pollution.
2) And (5) adopting an aspirator to perform suction treatment. The suction apparatus is mainly used as a wound-clearing apparatus in the thoracoscopy, the abdominal cavity endoscopy and the operation process. In the cavity operation, the washing treatment is carried out through the washing wound and the negative pressure suction wound to expose tissues; the smoke generated by the energy instrument is attracted, and the smoke is eliminated; the suction apparatus and the pneumoperitoneum machine are two mutually independent devices, the suction apparatus washes the wound surface and sucks liquid smoke and smoke to bring the change of an abdominal cavity space, the pressure balance of the abdominal cavity space is changed, and the suction flow of the suction apparatus is usually large, so that the pressure fluctuation in the endoscope is very large when the suction apparatus is used, and sometimes the abdominal pressure loss even occurs. Similarly, when the aspirator is adopted to suck waste liquid and blood stain in the abdominal cavity, the pressure balance of the abdominal cavity can be changed when the aspirator is an independent device.
In addition, the smoke generated by the combustion of the organic matter generated by the energy equipment is a strong carcinogen, and no matter the sleeve exhaust valve is opened or the suction device is used for suction, the gas is discharged to an operating room, so that unnecessary injuries are caused to an operator and medical staff in the operating room; direct reaction of CO 2 Discharged to the operating room, and will increase CO 2 The amount of CO used, and the pollution of the operating room and the gas source 2 The gas consumption will be greater.

Through adding the suction function, wash aspirator access device and pneumoperitoneum and establish equipment no longer each other independent equipment like this, pneumoperitoneum control and wash suction control and realize under same equipment, can realize closed loop feedback between. And the gas that attracts through the aspirator can return to the abdominal cavity through filtering, no longer discharges to the operating room, and then realizes the gaseous full closed loop management and control of abdominal cavity.
