Description

TECHNICAL FIELD

[0001] The utility model relates to the field of laparoscopic surgery, specifically for a waste gas drainage bottle for surgical smoke exhaust. BACKGROUND

[0002] At present, the abdominal cavity technology has been widely applied in various special operations, and doctors completely rely on the image information conducted by the endoscope during the laparoscopic surgery process to carry out the operation, therefore, it is extremely important to maintain the definition of real-time images during the operation; the common problems in the laparoscopic surgery mainly include: lens fogging, carbon dioxide and irritating gas smoke emission in the abdominal cavity.

[0003] Surgical smoke refers to gaseous substances generated during the operation process, also known as aerosol, burning smoke, etc., which is formed by gamma knife, high-frequency electric cauter, laser knife, ultrasonic surgical knife, high-speed drill, saw blade, instrument burr damage and vaporization of tissue protein and fat. Surgical smoke not only hinders the vision of the surgical staff, but also releases toxic and harmful substances into the air. Therefore, surgical smoke exhaust can timely remove the CO2 waste gas and smoke during the operation, clean the air in the operating room, and reduce the occupational hazards of medical staff.

[0004] Generally, the following methods are used to solve the problem:

[0005] ① A thermos cup is used to contain 70-80 degree hot sterilized water for injection, and the laparoscope lens is placed in the cup for preheating for ten seconds before being placed in the cup to prevent the lens from fogging, and the lens is placed in the cup for preheating after each time of lens contamination, and then wiped with clean gauze;

[0006] ② Iodophor gauze ball is used to wipe the lens, and then clean gauze is used to wipe, so that a thin film formed by iodine liquid is left on the lens, which can prevent the lens from fogging;

[0007] ③ The carbon dioxide gas inlet is converted, and the Trocar is not shared with the lens, so as to reduce the influence factor of low temperature of the lens;

[0008] ④ A special anti-fog oil is used to smear the lens.

[0009] These methods can only alleviate the lens fogging for a short time, and cannot fundamentally solve the problem of lens fogging.

[0010] The exhaust can be achieved through the following small skills:

[0011] 1) Directly connect the negative pressure aspirator tube to exhaust

[0012] The aspirator tube connection port is connected to the Trocar exhaust hole, the Trocar exhaust hole valve is opened, and the irritating gas and carbon dioxide are directly sucked by the negative pressure.

[0013] Disadvantages: the thick pipe diameter can easily affect the pressure in the laparoscope, and two sets of negative pressure aspirators are needed;

[0014] Advantages: active exhaust, clear surgical field, no emission of irritating gas and carbon dioxide during operation.

[0015] 2) Direct exhaust through drainage tube

[0016] Connect the drainage tube to the Trocar exhaust hole, and immerse the other end of the drainage tube in saline. Since carbon dioxide is soluble in water, it can reduce the emission of carbon dioxide into the operating room.

[0017] Disadvantages: passive exhaust, poor effect, pungent odor, and saline easily wetting the table;

[0018] Advantages: simple operation.

[0019] Therefore, the existing laparoscopic surgery lacks a special smoke exhaust collector when smoke is generated, and cannot treat smoke and harmful gases. The use of active exhaust will occupy the space of the operating field, which will affect the progress of laparoscopic surgery.

[0020] Therefore, it is necessary to design a new type of waste gas drainage bottle for surgical smoke exhaust to solve the above problems. Content of the utility model

[0021] The utility model aims at providing a waste gas drainage bottle for surgical smoke exhaust to solve the problems in the above background art.
