Description

Technical Field

[0001] This utility model relates to the field of medical consumables technology, and more specifically, to a laparoscopic surgery smoke extraction device and drainage equipment. Background Technology

[0002] In recent years, with the rapid development of medical technology, modern surgical tools such as electrosurgical equipment, laser scalpels, and ultrasonic scalpels have been widely used in clinical practice, greatly improving the precision and efficiency of surgical procedures. However, behind these advancements lies a problem that cannot be ignored: the potential threat to the health of medical staff posed by surgical fumes generated during surgery is becoming increasingly prominent. Surgical fumes are mainly composed of 95% water or water vapor and 5% cell debris in particulate form. This 5% particulate component contains blood and tissue fragments, harmful chemical components, active viruses, active cells, inactive particles, and mutagenic substances, seriously threatening the physical and mental health of doctors and patients, and also affecting the surgeon's field of vision.

[0003] Existing technologies offer three main types of protection against surgical fumes:

[0004] The first method is to use a smoke-removing electrosurgical pen, which features an integrated suction device in the electrosurgical head that can instantly remove the smoke generated during surgery, thereby reducing the impact of smoke on the environment. However, this type of device can only be used in electrosurgical procedures and cannot solve the smoke problem in ultrasonic scalpel surgery, thus limiting its applicability to certain surgical procedures.

[0005] The second method is to use an operating room ventilation system. This method usually requires a high-efficiency air purifier to ensure the air quality in the operating room. It relies on a smoke absorption and emission system installed in the operating room. This system exhausts the exhaust gas to the outside through an exhaust pipe installed in the operating room. However, this method is not only expensive and complicated to install, but it can only exhaust the exhaust gas in the air in the operating room and cannot immediately remove the smoke inside the patient's abdominal cavity, which in turn obstructs the surgical field of vision and affects the surgical procedure.

[0006] Thirdly, it relies on the personal protection of medical staff, such as wearing protective masks, which can reduce the inhalation of smoke and reduce the harm to the human body. However, the protective effect of this method is limited and it cannot effectively remove smoke from the operating room, especially from the patient's abdominal cavity, thus adversely affecting the surgical field of vision.

[0007] In conclusion, how to solve the problem of surgical smoke interfering with the surgical process in different surgical procedures is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The core of this utility model is to provide a laparoscopic surgery smoke exhaust device. The first branch for smoke exhaust and the drainage tube are combined into one through a three-way component. They use the negative pressure of the drainage device to exhaust smoke together. Without adding extra equipment, the smoke exhaust problem of different surgeries is solved. At the same time, a smoke purification device is integrated in the first branch to purify the smoke and prevent the odor from being generated in the operating room.

[0039] Another core aspect of this invention is to provide a surgical drainage device that includes the aforementioned laparoscopic surgery smoke extraction device, which can solve the same technical problem.

[0040] Please refer to Figures 1-3A laparoscopic surgery smoke exhaust device includes a three-way component 5, a main pipe 6 connected in series at the first interface of the three-way component 5, a first branch pipe 4 connected in series at the second interface, and a plug-in port provided at the third interface for plugging in the second branch.

[0041] The free end of the first branch pipe 4 is provided with a branch end connector 1, and the first branch pipe 4 is provided with a smoke purification device 2 and a flow rate adjustment component 3. The flow rate adjustment component 3 is used to adjust the internal flow rate of the first branch pipe 4.

[0042] The free end of the main pipeline 6 is provided with a main pipeline end connector 7.

[0043] like Figure 1 As shown, a three-way component 5 is used to split the main pipeline 6 into two parts. One end is equipped with a plug-in port for connecting the second branch, i.e., the original drainage pipeline. The other end is directly connected to the first branch pipe 4 used for smoke exhaust, so that the first branch pipe 4 and the second branch can work together using the negative pressure generated by the original drainage equipment, thus avoiding the need for additional equipment in the operating room.

[0044] Meanwhile, a smoke purification device 2 is integrated in the first branch pipe 4 to purify the smoke in the first branch pipe 4, preventing the smoke from escaping after entering the drainage equipment and causing odor in the operating room. This eliminates the impact of smoke on the surgical field of vision and also eliminates the harm of smoke to the surgical personnel.

[0045] Furthermore, a flow rate adjustment component 3 is integrated within the first branch tube 4, which can adjust the effective flow rate of the first branch tube 4, that is, adjust the negative pressure at the free end of the first branch tube 4, so as to avoid excessive extraction of gas from the patient's abdominal cavity due to excessive negative pressure, which would reduce the patient's abdominal space and affect the doctor's operating space, thereby ensuring the smooth progress of the operation.

[0046] In some embodiments, a filter disc 21 and an activated carbon adsorption mechanism 22 are arranged sequentially inside the smoke purification device 2.

[0047] Several sets of filter screens are arranged sequentially inside the filter disc 21, and the mesh count of the filter screen on the downstream side is greater than that of the filter screen on the upstream side.

[0048] The activated carbon adsorption mechanism 22 includes several stacked activated carbon layers, and gaps are provided between adjacent activated carbon layers to allow airflow to pass through.

[0049] like Figure 1 and Figure 2As shown, the smoke purification device 2 uses two-stage filtration. First, the filter screen in the filter disc 21 performs primary filtration of the flue gas to remove large particles. At the same time, the filter disc 21 is equipped with several layers of stacked filter screens, and the mesh size of the filter screens increases progressively, which effectively slows down the clogging cycle of the filter screens and ensures the rated removal effect of large particles in the flue gas.

[0050] Meanwhile, the smoke purification device 2 also integrates an activated carbon adsorption mechanism 22 to perform secondary adsorption filtration on the smoke. With the adsorption capacity of activated carbon, small particulate matter in the smoke is adsorbed and removed, thereby eliminating the odor in the smoke, preventing the odor from spreading, and thus preventing the generation of odors in the operating room.

[0051] In some embodiments, the flux adjustment assembly 3 includes a micro-dose adjustment device, the two ends of which are connected in series within the first branch pipe 4;

[0052] The micro-dose adjustment device includes a fixed part and an adjustment part that rotate relative to each other. Both the fixed part and the adjustment part are equipped with valve plates. The valve plates are provided with valve holes on their surfaces. When the two sets of valve plates rotate relative to each other, the overlapping conduction area of ​​the two sets of valve holes changes.

[0053] The surfaces of the fixing part and the adjusting part of the micro-dose adjustment device are provided with anti-slip texture 31. The surface of the fixing part is provided with an indicator strip 33, and the corresponding position of the surface of the adjusting part is provided with a flow bar 32, which is used to indicate the actual flow rate of the micro-dose adjustment device.

[0054] like Figure 1 and Figure 3 As shown, a flow rate regulating component 3 is connected in series in the first branch pipe 4. By controlling the flow rate regulating component 3, the gas flow rate in the first branch pipe 4 is changed, thereby changing the pressure at the free end of the first branch pipe 4, and thus controlling the smoke exhaust speed and adsorption intensity. This prevents objects on both sides from moving towards the free end of the first branch pipe 4 due to insufficient pressure in the surgical area, thereby preventing negative pressure closure in the surgical area and affecting the surgical operating space.

[0055] The micro-dose adjustment device is used as the flux adjustment component 3. The two sets of valve plates inside rotate relative to each other, which can accurately control the flux in the pipeline and the adjustment process is simple and easy to execute. Moreover, anti-slip textures 31 are provided on the outer periphery of both the fixed part and the adjustment part to avoid slippage and other difficult-to-control problems during the adjustment process. At the same time, indicator strips 33 and flow strips 32 are set at corresponding positions on the outer periphery of the fixed part and the adjustment part, which can intuitively display the current flux in the micro-dose adjustment device.

[0056] In some embodiments, the flux regulation assembly 3 includes an adjustable Robert clamp that snaps onto the outside of the first branch pipe 4.

[0057] An adjustable Robert clamp is used as the flow rate regulating component 3. It does not need to be connected in series inside the first branch pipe 4, but only needs to be snapped onto the outside of the first branch pipe 4. The Robert clamp does not come into direct contact with the flue gas, thereby reducing the number of interfaces inside the first branch pipe 4 and avoiding flue gas leakage caused by assembly sealing problems.

[0058] In some embodiments, the branch end connector 1 includes a Luer connector for connecting the valve of the puncture device.

[0059] like Figure 1 As shown, the branch end connector 1 adopts a Luer connector, which facilitates communication and fixation with a variety of existing surgical instruments, thereby enabling this application to be applied to different surgical procedures and improving the applicability of this application. For example, when connected to the valve of the trocar, the surgical smoke inside the abdominal cavity can be directly discharged after the trocar enters the abdominal cavity, reducing the obstruction of the surgical view.

[0060] In some embodiments, the tee assembly 5 is a U-shaped or Y-shaped tee, the main pipe 6 is connected to the main interface of the tee, and the first branch pipe 4 and the plug-in port are connected to the secondary interface of the tee respectively.

[0061] A U-shaped or Y-shaped tee connects the main pipe 6, the first branch pipe 4, and the drainage pipe. The main pipe 6 is used to connect and communicate with the drainage equipment, the first branch pipe 4 is used for smoke exhaust, and the drainage pipe is used for liquid drainage. Both the first branch pipe 4 and the main pipe 6 are directly fixed to the tee by adhesive bonding or interference fit. The drainage pipe is connected to the tee by an interference fit with a plug-in port. This allows the drainage pipe and the present application to be used in combination. Both the present application and the drainage pipe can be made from conventional medical materials in the prior art to produce disposable sterile consumables, ensuring the sterility and safety of the surgical environment.

[0062] In some embodiments, the three-way assembly 5 is a directional valve, the main pipeline 6 is connected to the common end of the directional valve, the first branch pipeline 4 is connected to the normally open end of the directional valve, and the plug-in port is connected to the normally closed end of the directional valve.

[0063] Using a reversing valve as the three-way component 5 allows the first branch pipe 4 and the second branch pipe to be connected in a time-separated manner. During the surgical procedure, by controlling the reversing valve, the first branch pipe 4 or the second branch pipe can be connected independently for smoke exhaust or liquid drainage, thereby improving the efficiency of smoke exhaust or drainage. At the same time, it can help reduce the power of the drainage equipment, reduce equipment noise, and save equipment energy consumption.

[0064] In some embodiments, the three-way assembly 5 is a proportional valve, the main pipeline 6 is connected to the common end of the proportional valve, and the first branch pipeline 4 and the plug-in port are connected to the other two ports of the proportional valve.

[0065] A proportional valve is used as the three-way component 5. By controlling the proportional valve, the conduction ratio of the first branch pipe 4 and the second branch pipe is adjusted. Even if there is a pressure difference between the free ends of the first branch pipe 4 and the second branch pipe, the drainage speed and smoke exhaust speed can be adjusted according to the actual surgical needs, thereby ensuring the smooth progress of the operation and effectively reducing the noise and power of the drainage equipment.

[0066] In addition to the laparoscopic surgery smoke extraction device disclosed in the above embodiments, this utility model also provides a surgical drainage device including the above-mentioned laparoscopic surgery smoke extraction device. For the structure of other parts of the surgical drainage device, please refer to the prior art, which will not be described in detail here.

[0067] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The above provides a detailed description of the laparoscopic surgery smoke extraction device and drainage equipment provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
