Description

Technical Field

[0001] This utility model relates to the field of experimental equipment, specifically a surgical smoke collection device for simulating a surgical microenvironment. Background Technology

[0002] The surgical microenvironment refers to the environmental characteristics within a 15-20cm radius of the surgical incision during surgical procedures. Surgical fumes are toxic and harmful substances produced when energy instruments cut physiological tissues during surgery, causing water in cells to heat and boil, resulting in localized dryness and high-temperature coagulation.

[0003] Related studies have shown that surgical fumes contain high concentrations of particulate matter, harmful chemicals, and mutagenic substances, making them a major source of air pollution in operating rooms. Because surgeons are in this microenvironment for extended periods, their respiratory systems are highly susceptible to inhaling harmful components from the fumes. These pollutants can then enter the bloodstream through the alveoli, posing a serious threat to health. Polycyclic aromatic hydrocarbons (PAHs), in particular, have attracted significant attention due to their potent carcinogenicity.

[0004] Therefore, this invention constructs a surgical microenvironment simulation system to quantitatively detect and analyze particulate matter and polycyclic aromatic hydrocarbons in surgical fumes, aiming to provide a scientific basis for formulating effective protective measures and thereby strengthen the occupational health protection of surgeons.

[0005] The current experimental chambers on the market fail to meet the needs of relevant research mainly in the following aspects: 1. Insufficient sufficiency: There are currently no surgical smoke collection devices for simulated surgical microenvironments on the market; 2. Insufficient data acquisition and analysis functions: Some experimental chambers have limited data acquisition and analysis functions, which cannot meet the high-precision requirements and affect the accuracy of experimental results; 3. Insufficient scalability: Some experimental chambers do not support modular expansion, making it difficult to adapt to new experimental needs; 4. Insufficient durability and maintenance: Some experimental chambers are made of non-durable materials, are easily damaged, and are complex to maintain, increasing usage costs; 5. Insufficient compatibility: Some experimental chambers have poor compatibility with other equipment, making it difficult to integrate them into existing experimental systems; 6. Insufficient safety: Some experimental chambers have potential risks in terms of biosafety, electrical safety, and material safety. Improvements will enhance the practicality and user experience of the experimental chambers. Utility Model Content

[0017] Figure 1 This is a schematic diagram of the structure of this utility model;

[0018] Figure 2 yes Figure 1 A three-dimensional structural diagram of the middle box. Detailed Implementation

[0019] like Figure 1 and 2As shown, a surgical smoke collection device simulating a surgical microenvironment includes a rectangular box 1 made of transparent acrylic material, placed on a worktable. The box has a cuboid structure of 600mm*400mm*416mm. An electrosurgical unit a is placed on the worktable on one side of the box 1. One pole of the electrosurgical unit a is connected to a negative electrode plate, and the other pole is connected to the electrosurgical unit. The negative electrode plate and the electrosurgical unit are placed at the center of the bottom of the box through the electrosurgical unit's inlet.

[0020] A negative pressure suction device b is placed on the workbench on the other side of the housing 1. Since both the electrosurgical unit and the negative pressure suction device are purchased components in the existing technology, their structures will not be described in detail here.

[0021] A specimen delivery window 1b is provided on the side wall of the back side of the box 1. The window size is 300mm*200mm, which allows specimens to enter and exit the box. The specimen delivery window and the window sealing plate are automatically aligned and sealed by magnetic attraction.

[0022] On one side wall of the front of the housing 1, there is a pair of glove-passing openings 1a with a diameter of 15mm. A connecting channel 2 extends outward from the glove-passing opening 1a to connect with a plastic glove (not shown in the figure). The plastic glove is placed in the connecting channel 2 and then fixed by cable ties.

[0023] A lifting bracket 3 is installed on the upper surface of the housing 1. The lifting bracket 3 is made entirely of 6061 silver-white aluminum alloy. The lifting bracket 3 includes a pair of spaced-apart brackets 3a. Longitudinally distributed sliding grooves 3b are provided on the inner side of the brackets 3a, and the two sliding grooves 3b are correspondingly distributed.

[0024] Each of the two slide grooves 3b has a corresponding sliding block 3c, and a crossbeam 3d spans between the two sliding blocks 3c. A locking pin (not shown in the figure) corresponding to the slide groove 3b is also installed on the sliding block 3c. A top beam 3e spans the top of the two supports 3a, and a trident-shaped parallel distributor 4b is inserted into the top beam 3e. For ease of viewing, Figure 2 The top beam 3e and the diverter 4b are not shown in the diagram.

[0025] Three rotor flow meters 4 are installed side by side and evenly distributed on the crossbeam 3d. Each rotor flow meter 4 is equipped with an interface 4a that is connected to the negative pressure device. Each interface 4a has one end connected to the same parallel flow divider 4b. One end of the parallel flow divider 4b is connected to the air inlet pipe of the negative pressure device b.

[0026] Each rotor flowmeter 4 is connected to the detection pipeline assembly 6 via a 90-degree elbow gas pipeline quick-connect plug at its inlet end.

[0027] The housing 1 has three through holes 5 that correspond one-to-one with the detection pipeline assembly 6, so that one end of the detection pipeline assembly 6 passes through the through hole 5 and is partially inserted into the housing 1.

[0028] The detection pipeline assembly 6 includes a first flexible tube 6a connected to the rotor flow meter 4, a Tenax TA stainless steel analytical tube 6b connected to the lower end of the first flexible tube 6a and inserted into the through hole 5, a second flexible tube 6c inserted into the lower end of the Tenax TA stainless steel analytical tube 6b located in the housing 1, and a polytetrafluoroethylene filter membrane clip 6d inserted into the lower end of the second flexible tube 6c.

[0029] A set of particulate matter monitoring holes 7 is also provided on the housing 1 on one side of the through hole 5. A corresponding removable plug (not shown in the figure) is installed on the particulate matter monitoring holes 7 for use by a handheld particulate matter detector.

[0030] An air inlet 1c is provided at the bottom of the housing 1 to ensure smooth suction when the negative pressure suction device is performing its suction function. An electric knife inlet 1d is provided at the bottom of the housing 1.

[0031] Work process:

[0032] First, place the electrosurgical unit and corresponding electrode plate a1 on the bottom surface of the chamber through the sample submission window on the back of the chamber. Pull the wires of the electrosurgical unit and electrode plate out from the electrosurgical unit's wire inlet hole on the chamber and make an electrical connection with the electrosurgical unit. Then, attach a plastic glove to the connection channel 2, with the handheld end of the glove placed inside the chamber. Next, open the sample submission window on the back of the chamber, place the experimentally cut tissue on the electrode plate, close the sample submission window, and finally turn on the negative pressure suction device, adjust the flow rotor on the rotor flow meter, start the electrosurgical unit, turn on the dust particle detector, and conduct the tissue cutting experiment. The surgical fumes generated during cutting pass through the detection pipeline assembly, adsorbing the associated compounds onto the PTFE filter membrane inside the TenaxTA stainless steel analytical tube and the PTFE filter membrane clamp. Collecting multiple surgical fumes samples at the same time will greatly improve experimental efficiency, reduce systematic errors, and improve the objectivity and accuracy of the experiment.
