Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to smog filter equipment that laparoscopic surgery used.
Background
The operation smoke refers to gaseous substances generated by cutting, electrocoagulation or vaporization of tissue and organs by medical equipment such as a high-frequency electric knife, an ultrasonic scalpel, a laser knife and the like used by operating personnel in the operation process. The literature reports that surgical smoke is composed of 95% water vapor and 5% cellular debris in the form of particles containing active viruses, active cells, blood and tissue debris, harmful chemical components, and substances that induce genetic mutations, among others. For a long time, when a surgeon performs a laparoscopic surgery, because smoke generated by the surgical operation seriously interferes with the sight of a surgeon, the surgery smoke is usually discharged by opening an air injection valve of a puncture outfit for the laparoscopic surgery, so that carbon dioxide gas containing harmful substances overflows the abdominal cavity and is dispersed to a surgical room. After the surgical personnel inhale surgical smoke, uncomfortable symptoms such as headache, dizziness, nausea and the like can appear, and the surgical safety and the health of medical personnel are seriously threatened. Therefore, there is a need for a filtering and adsorbing device capable of effectively filtering harmful smoke and absorbing carbon dioxide leaked out of the abdominal cavity in laparoscopic surgery.
The existing operation gas filtering device for the laparoscope has the defects of complex structure, high cost, inconvenience in operation, need of external power support and the like, and is difficult to popularize and apply in all levels of medical institutions.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. connecting a pipeline; 2. a filtration adsorption tank; 3. an air inlet; 4. a one-way valve; 5. an activated carbon particle layer; 6. a perforated partition plate; 7. a layer of sodium lime particles; 8. a non-porous separator; 9. an air outlet; 10. a gas storage bag; 11. a flow port.
Detailed Description
As shown in fig. 1, the smoke filtering device for laparoscopic surgery of the present invention comprises a connecting pipeline 1, a filtering and adsorbing tank 2, a check valve 4 and an air storage bag 10, wherein one end of the connecting pipeline 1 is connected to a top air inlet 3 of the filtering and adsorbing tank 2, the check valve 4 is installed in the top air inlet 3, and the check valve 4 is designed in the air inlet 3 of the filtering and adsorbing tank 2; the gas storage bag 10 is communicated with a gas outlet 9 at the top of the filtering and adsorbing tank, so that the unabsorbed carbon dioxide gas can be prevented from leaking, a vertical baffle 8 is arranged in an inner cavity of the filtering and adsorbing tank between the gas inlet 3 and the gas outlet 9, a flow port 11 is reserved between the bottom of the vertical baffle 8 and the inner bottom wall of the filtering and adsorbing tank 2, namely the vertical baffle divides the inner cavity of the filtering and adsorbing tank into two cavities with communicated bottoms, and adsorbing particles are arranged in the cavity of the filtering and adsorbing tank corresponding to the side of the gas inlet 3 at the top; the adsorption particles comprise an upper layer and a lower layer, the upper layer is an activated carbon particle layer 5, and the lower layer is a sodium lime particle layer 7 (changing into pink after absorbing carbon dioxide) added with a color-changing indicator and separated by a horizontal perforated partition plate 6.
The material of the filtering adsorption tank is transparent medical polypropylene. The connecting pipeline is made of ethylene-vinyl acetate copolymer, and the other end of the connecting pipeline is connected with the puncture outfit gas injection valve for the laparoscope. The air storage bag is made of silicon rubber.
The one-way valve 4 in the air inlet 3 can prevent the smoke of the operation from reversely flowing into the abdominal cavity, and the residual carbon dioxide and water vapor enter the air storage bag 10 through the air outlet 9, so that the carbon dioxide gas is prevented from leaking to pollute the air in the operation room.
Before the laparoscopic surgery is started, the connecting pipeline is connected with the puncture outfit gas injection valve for the laparoscope. Smog generated by cutting and electrocoagulation tissues such as a high-frequency electrotome and an ultrasonic scalpel in the operation disturbs the sight of an operator, an assistant opens an air injection valve of a puncture outfit for the laparoscope, carbon dioxide gas containing active viruses, cells and harmful chemical components enters an active carbon particle layer and a sodium lime particle layer containing a color-changing indicator through an air inlet of a filtering adsorption tank, harmful substances and the carbon dioxide gas are absorbed, and the sodium lime particle layer containing the color-changing indicator becomes pink after absorbing carbon dioxide. The one-way valve at the air inlet of the filtering adsorption tank can prevent the smoke of the operation from flowing back into the abdominal cavity. If excessive carbon dioxide gas is discharged during the operation, the gas storage bag at the gas outlet of the filtering and adsorbing tank is expanded, the internal pressure of the connecting pipeline and the filtering and adsorbing tank is reduced to be lower than the internal pressure of the abdominal cavity, and the carbon dioxide gas is prevented from leaking to an operation room. After the operation is finished, the medical staff removes the filtering device and processes the medical waste according to the medical waste.
The utility model has the advantages of simple structure, convenient use, safety, reliability and the like, can ensure the smooth implementation of the laparoscopic surgery, lightens the environmental pollution of the surgery and ensures the health of medical staff.
