Smoke evacuating electrocoagulation device

Abstract

This application discloses a smoke extraction electrocoagulation device, comprising: a smoke extraction electrocoagulation hook, which has a flue inside, including an inlet and an outlet, which are located on the smoke extraction electrocoagulation hook. Smoke enters from the inlet, passes through the flue, and is then discharged from the outlet; and a smoke extraction device, which is positioned corresponding to the outlet of the flue, with the outlet open relative to the smoke extraction device, allowing the smoke discharged from the outlet to directly contact the atmosphere. The smoke extraction device is used to extract the smoke discharged from the outlet. The smoke extraction electrocoagulation hook and the smoke extraction device are independently configured, and the outlet is open relative to the smoke extraction device. Therefore, when smoke extraction is not required, the smoke extraction device stops operating, and the outlet of the flue is directly connected to the atmosphere. In this case, the smoke extraction electrocoagulation hook will not generate a continuous negative pressure suction at the inlet of the flue during use, effectively preventing the inhalation of human tissue fragments from the flue during electrocoagulation.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically to a smoke extraction electrocoagulation device. Background Technology

[0002] Currently, electrocoagulation is a core surgical technique in hepatobiliary surgery, widely used in critical steps such as liver parenchyma transection, vascular hemostasis, and bile duct ablation. However, the high-temperature fumes and tissue vaporization particles generated during electrocoagulation pose significant challenges to the surgical process. Due to the complex anatomical structure of the hepatobiliary region, traditional fume extraction electrocoagulation equipment often struggles to balance efficient fume extraction with operational safety.

[0003] For example, in related technologies, the smoke extraction electrocoagulation hook that integrates the flue and exhaust electrocoagulation works by continuously applying negative pressure. During the electrocoagulation hemostasis process, it will generate tearing force on the surrounding normal tissue. The large negative pressure attraction can easily draw liver tissue fragments, blood clots, or small bile ducts into the flue, which can easily cause uncontrollable postoperative bleeding or infection. At the same time, it can easily block the flue, affect the smoke extraction efficiency, and even contaminate the surgical environment. Utility Model Content

[0004] The purpose of this application is to provide a smoke extraction electrocoagulation device to avoid the adverse effects of continuous negative pressure on intraoperative tissues and reduce the risk of debris being inhaled into the smoke duct.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A smoke extraction electrocoagulation device is provided, comprising: a smoke extraction electrocoagulation hook, wherein a flue is provided within the smoke extraction electrocoagulation hook, the flue including an inlet and an outlet, the inlet and the outlet being located on the smoke extraction electrocoagulation hook, smoke entering from the inlet, passing through the flue, and then exiting from the outlet; and a smoke extraction device, wherein the smoke extraction device is positioned corresponding to the outlet of the flue, the outlet being open relative to the smoke extraction device, and the smoke discharged from the outlet directly contacting the atmosphere, the smoke extraction device being used to extract the smoke discharged from the outlet.

[0006] As a preferred embodiment, the flue gas electrocoagulation hook includes: a control handle, a sleeve, and an electric hook. The control handle is connected to the sleeve, and the main body of the electric hook is disposed inside the sleeve. The electric hook is electrically connected to the control handle, and the end of the electric hook extends out of the sleeve so that the end of the electric hook can be controlled by the control handle to complete the electrocoagulation action. The air inlet of the flue is disposed in the sleeve, and the flue extends through the sleeve to the control handle so that the air outlet is disposed at the control handle.

[0007] As another preferred embodiment, the flue includes a first flue pipe and a second flue pipe, which are disposed opposite to each other within the sleeve, so that the smoke is discharged from the outlet through the first flue pipe and the second flue pipe.

[0008] Further preferably, the control handle is provided with a receiving cavity, one side of which is connected to the first flue pipe and the second flue pipe, and the other side of which is connected to the air outlet; wherein, smoke is introduced into the receiving cavity by the first flue pipe and the second flue pipe, and after being temporarily stored in the receiving cavity, the smoke is discharged through the air outlet.

[0009] In a further preferred embodiment, the containment cavity is provided with a guide wall, and the air outlet is located near the guide side of the guide wall, so that the smoke in the containment cavity is guided by the guide wall to converge to the air outlet for discharge.

[0010] Further preferably, the location of the air outlet corresponds to the smoke rising path of the first flue pipe, and the guide wall is disposed on the smoke rising path of the second flue pipe.

[0011] Preferably, a filter element is provided at the air inlet of the flue.

[0012] Furthermore, the filter element includes: an opening that communicates with the flue and is formed on the outer wall of the sleeve; a filter screen assembly that includes a filter screen and a plug-in end that is connected to the filter screen; wherein, the filter screen is inserted into the opening to filter debris in the flue path, and the plug-in end protrudes from the outer wall of the sleeve.

[0013] Furthermore, the control handle is provided with a viewing window that extends into the receiving cavity, allowing observation of the smoke state within the receiving cavity through the viewing window.

[0014] Furthermore, a one-way valve is provided inside the flue to prevent smoke backflow.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] The smoke extraction electrocoagulation hook is independently set up from the smoke extraction device, and the air outlet is open relative to the smoke extraction device. Therefore, when smoke extraction is not required, the smoke extraction device stops operating, and the air outlet of the flue is directly connected to the atmosphere. Since the smoke extraction device does not provide any suction at this time, the smoke extraction electrocoagulation hook will not generate a continuous negative pressure suction at the air inlet of the flue during use. This effectively avoids the inhalation of human tissue fragments in the flue during electrocoagulation, and also avoids trauma to the electrocoagulation site caused by continuous negative pressure suction.

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] In a preferred embodiment, see Figures 1 to 5 This application provides a smoke extraction electrocoagulation device 1, comprising: a smoke extraction electrocoagulation hook 10, wherein a flue 30 is provided inside the smoke extraction electrocoagulation hook 10, the flue 30 includes an air inlet 31 and an air outlet 32, the air inlet 31 and the air outlet 32 ​​are opened on the smoke extraction electrocoagulation hook 10, smoke enters from the air inlet 31, passes through the flue 30, and is then discharged from the air outlet 32; and a smoke extraction device 20, which is set corresponding to the air outlet 32 ​​of the flue 30, the air outlet 32 ​​is open relative to the smoke extraction device 20, and the smoke discharged from the air outlet 32 ​​is in direct contact with the atmosphere, and the smoke extraction device 20 is used to extract the smoke discharged from the air outlet 32.

[0028] In the specific use of the smoke extraction electrocoagulation device 1, the smoke extraction electrocoagulation hook 10 is externally powered for electrocoagulation operations, and the smoke extraction device 20 is also externally powered to provide suction for the smoke. During the operation, when the smoke extraction electrocoagulation hook 10 is used for electrocoagulation cutting, hemostasis, or other operations, the generated smoke will enter from the air inlet 31 of the smoke duct 30 provided inside the smoke extraction electrocoagulation hook 10, rise along the smoke duct 30, and finally be discharged from the air outlet 32. The smoke discharged into the atmosphere is then inhaled by the smoke extraction device 20. Meanwhile, since the smoke exhaust electrocoagulation hook 10 and the smoking device 20 are set independently, and the air outlet 32 ​​is open relative to the smoking device 20, the smoking device 20 stops operating when smoking is not required. At this time, the air outlet 32 ​​of the flue 30 is directly connected to the atmosphere. Since the smoking device 20 does not provide a certain suction force at this time, the smoke exhaust electrocoagulation hook 10 will not generate a continuous negative pressure suction at the air inlet 31 of the flue 30 during use, effectively avoiding the inhalation of human tissue fragments during electrocoagulation, and avoiding trauma to the electrocoagulation site caused by continuous negative pressure suction.

[0029] The smoking device 20 and the exhaust electrocoagulation hook 10 are independently set, and the exhaust port 32 is directly connected to the atmosphere. This ensures that the negative pressure suction is generated only when the smoking device 20 is running, and the negative pressure environment in the flue 30 is eliminated relatively quickly. Compared to related technologies where the flue 30 is directly connected to the negative pressure equipment, a negative pressure environment will remain in the flue 30 for a longer period after the negative pressure equipment stops running, making it impossible to eliminate the negative pressure environment quickly. For example, when electrocoagulation requires precise hemostasis or treatment of fragile tissue, the smoking device 20 can be turned off at any time to eliminate the continuous negative pressure in the flue 30, preventing the suction of normal tissue fragments or blood clots from being drawn into the flue 30, thereby reducing accidental injury and postoperative complications.

[0030] It should be noted that the smoking device 20 is composed of a vortex fan 21, and the smoking device 20 is equipped with an exhaust pipe 22, which can be connected to an external medical waste bin to collect surgical smoke.

[0031] As a preferred embodiment, the flue gas electrocoagulation hook 10 includes: a control handle 11, a sleeve 12, and an electric hook 13. The control handle 11 is connected to the sleeve 12, and the main body of the electric hook 13 is disposed inside the sleeve 12. The electric hook 13 is electrically connected to the control handle 11, and the end of the electric hook 13 extends out of the sleeve 12 so that the end of the electric hook 13 can be controlled by the control handle 11 to complete the electrocoagulation action. The air inlet 31 of the flue 30 is disposed in the sleeve 12, and the flue 30 extends through the sleeve 12 to the control handle 11 so that an air outlet 32 ​​is disposed at the control handle 11.

[0032] Specifically, the control handle 11 is equipped with a control board, which integrates a control circuit to control the electrocoagulation effect of the smoke exhaust electrocoagulation hook 10. That is, the control handle 11 is equipped with an electrocoagulation control key 14. The electric hook 13 is electrically connected to the control board integrated in the control handle 11 through an electrical connection wire 15. Medical staff can then control the electric hook 13 to perform electrocoagulation operation through the electrocoagulation control key 14.

[0033] The sleeve 12 is fitted over the electrocautery hook 13 and is made of insulating material, such as medical polymer material or ceramic coating. This effectively isolates the high-frequency current of the electrocautery hook 13 during operation, preventing the current from being accidentally conducted to non-target tissues or surgical instruments through the sleeve 12. This reduces the risk of intraoperative short circuits, burns to surrounding healthy tissues, or accidental electric shocks. Especially when operating in complex cavities or narrow spaces, the encapsulating design of the insulating sleeve 12 ensures that the current acts only on the specific area contacted by the tip of the electrocautery hook 13, improving the accuracy and controllability of electrocoagulation.

[0034] In a further preferred embodiment, the electric hook 13 can be telescopically extended relative to the sleeve 12. Specifically, a slider can be provided on the electric hook 13 and a slide rail can be provided on the inner wall of the sleeve 12 to realize the telescopic extension of the electric hook 13 relative to the sleeve 12, thereby adapting to different surgical conditions. The slider is also made of an insulating material.

[0035] As another preferred option, see Figure 4 The flue 30 includes a first flue pipe 33 and a second flue pipe 34, which are disposed opposite to each other within the sleeve 12, so that the smoke is discharged from the outlet 32 ​​through the first flue pipe 33 and the second flue pipe 34.

[0036] Further preferably, the control handle 11 is provided with a receiving cavity 111. One side of the receiving cavity 111 is connected to the first flue pipe 33 and the second flue pipe 34, and the other side of the receiving cavity 111 is connected to the air outlet 32. Smoke is introduced into the receiving cavity 111 through the first flue pipe 33 and the second flue pipe 34. After the smoke is temporarily stored in the receiving cavity 111, it is discharged through the air outlet 32.

[0037] Therefore, in actual operation, the smoking device 20 needs to be turned on first. After a certain negative pressure is generated in the receiving cavity 111, the smoke exhaust electrocoagulation hook 10 is operated to perform surgical electrocoagulation, thereby smoking through the flue 30. When smoking is no longer needed, the smoking device 20 is turned off, and a small amount of smoke remaining in the receiving cavity 111 is directly discharged into the atmosphere. The receiving cavity 111 is directly connected to the atmospheric environment. Therefore, there is no negative pressure environment in the receiving cavity 111 at this time, and smoke is not absorbed in the flue 30. This effectively avoids continuous negative pressure adsorption in the flue 30 and prevents human tissue from being inhaled into the flue 30 during surgery.

[0038] Further preferably, the receiving cavity 111 is provided with a guide wall 112, and the air outlet 32 ​​is located near the guide side of the guide wall 112. Thus, the smoke within the receiving cavity 111 is guided by the guide wall 112 to converge and be discharged through the air outlet 32. The guide wall 112 has an arc-shaped geometry, which, through physical obstruction and airflow guidance in the arc segment, forces the disordered smoke dispersed within the receiving cavity 111 to a predetermined path, reducing the generation of eddies and turbulence. This directional flow prevents the smoke from randomly spreading or stagnating within the cavity, causing the smoke to converge along the surface of the guide wall 112 towards the air outlet 32.

[0039] In a further preferred embodiment, the location of the air outlet 32 ​​corresponds to the smoke rising path of the first flue pipe 33, and the guide wall 112 is located on the smoke rising path of the second flue pipe 34.

[0040] Specifically, the smoke rises from branch to main. Specifically, the smoke is simultaneously drawn in by the first flue pipe 33 and the second flue pipe 34, and after being lifted by the pipes, it is led out into the receiving cavity 111. That is, the smoke in the first flue pipe 33 enters the receiving cavity 111 along the X1 direction and is simultaneously discharged to the air outlet 32 ​​along the X1 direction. At the same time, the smoke in the second flue pipe 34 enters the receiving cavity 111 along the X2 direction. Then, after being guided by the guide wall 112, the smoke converges into the air outlet 32 ​​along the X3 direction and is discharged. The smoke discharged from the air outlet 32 ​​can be absorbed by the smoking device 20.

[0041] Preferred, see Figure 4 and Figure 5 A filter element 40 is provided at the air inlet 31 of the flue 30.

[0042] Furthermore, the filter element 40 includes: an opening 41, which communicates with the flue 30 and is formed on the outer wall of the sleeve 12; and a filter screen 42 assembly, which includes a filter screen 42 and a plug-in end 43, which is connected to the filter screen 42. The filter screen 42 is inserted into the opening 41 to filter debris along the path of the flue 30, and the plug-in end 43 protrudes from the outer wall of the sleeve 12.

[0043] Specifically, the filter 42 can adopt a multi-layer composite structure, such as a stainless steel fine mesh superimposed with a polymer fiber filter membrane, which can intercept large molecular impurities such as tissue debris, carbonized particles, and blood clots generated during electrocoagulation, preventing them from entering the flue 30 and causing blockage. Through graded filtration using filter screens of different pore sizes, such as a coarse filter layer intercepting large particles and a fine filter layer blocking micron-sized particles, both smoke extraction efficiency and the lifespan of the device can be guaranteed. Due to the continuous nature of the smoke extraction process, the filter screen needs to be replaced frequently. Therefore, this application provides a plug-in end 43 protruding from the outer wall of the sleeve 12 on the filter screen 42 assembly. Medical personnel only need to pinch the plug-in end 43 to pull the filter screen 42 assembly out of the opening 41, achieving convenient and quick filter replacement.

[0044] Further preferably, the insertion end 43 can be designed as a snap-on or magnetic structure to improve the stability of the filter screen 42 assembly relative to the sleeve 12, while the magnetic structure facilitates the accurate insertion of the filter screen 42 assembly relative to the opening 41.

[0045] Furthermore, the control handle 11 is provided with a viewing window 50 that extends into the receiving cavity 111, allowing observation of the smoke state within the receiving cavity 111. Additionally, a one-way valve 60 is provided within the flue 30. Preferably, the one-way valve 60 is located between the first flue pipe 33 and the receiving cavity 111, and between the second flue pipe 34 and the receiving cavity 111, to prevent smoke backflow. The one-way valve 60, such as a duckbill valve or butterfly valve, is controlled by a flexible valve plate or gravity, allowing airflow only from the inlet 31 to the outlet 32. When the external negative pressure pauses or fluctuates, the valve automatically closes to prevent smoke that has entered the receiving cavity 111 from flowing back into the first flue pipe 33 or the second flue pipe 34, thus avoiding secondary contamination of the surgical area.

[0046] Specifically, the visualization window 50 is a transparent structure. The visualization window is preferably made of transparent high-temperature resistant materials, such as quartz glass or polycarbonate. The operator can directly observe the density, color and flow state of the smoke in the containment cavity 111, observe whether human tissue fragments are accidentally inhaled, and thus adjust the filter state in time. The side wall of the containment cavity 111 is sealed, and the smoke is discharged only through the air outlet 32.
