Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] In this embodiment, as Figures 1-6 As shown, an electrosurgical suction tube includes a handle 10 for easy handholding. An electrosurgical knife 20 and a first suction tube 30 are fixedly mounted inside the handle 10, allowing simultaneous suction during electrosurgical cutting without the need for assistance, thus conserving medical resources. Both the first and second suction tubes 30 are made of high-temperature resistant materials to prevent damage from heat generated by the blade 23 during cutting. One end of the first suction tube 30 extends to the outside of the handle 10 and connects to the suction end of a negative pressure aspirator 40. The negative pressure aspirator 40 is a standard surgical instrument commonly used in the medical field for removing smoke and blood, providing a clearer surgical field and reducing the risk of infection. The other end of the first suction tube 30 is fixedly connected to a suction kit for absorbing smoke. The device handle 10 contains a second suction tube 50 located below the handle 10. The second suction tube 50 is connected to the handle 10 via a fixing component, and the other end of the second suction tube 50 is also connected to the negative pressure suction device 40. Both the first suction tube 30 and the second suction tube 50 have suction effects. The smoke generated during the operation will be sucked away by the first suction tube 30, which can extract the undispersed surgical smoke at close range. At the same time, the second suction tube 50 can be used for auxiliary suction to expand the suction range and ensure that the smoke is sucked away. Several control buttons 60 are evenly distributed on the outer surface of the handle 10. The control buttons 60 are electrically connected to the electrosurgical knife 20 and the negative pressure suction device 40. The control buttons 60 can be used to control the extension length of the internal blade 23 of the electrosurgical knife 20, the opening and closing state of the negative pressure suction device 40, etc., so that the device can be used normally.

[0024] Among them, such as Figures 2-5As shown, the electric knife 20 includes a handle 21, a shank 22, a blade head 23, and a power cord 24. The blade head 23 has internal units for electric cutting and electrocoagulation, which is existing technology. The shank 22 is fixedly connected to the blade head 23 and is slidably disposed inside the handle 21. An electric telescopic component 25 is disposed inside the handle 21. The electric telescopic component 25 can be configured as an electric push rod. The telescopic end of the electric telescopic component 25 is fixedly connected to the shank 22, which facilitates adjustment of the extension length of the blade head 23 and allows the blade head 23 to be retracted into the flared opening 80 when not in use, thus providing protection. The power cord 24 is electrically connected to the electric telescopic component 25 and is also connected to the internal electronic unit of the blade head 23 for easy power supply.

[0025] Among them, such as Figure 3 and Figure 4 As shown, the blade 23 pierces into the interior of the first straw 30 from the side, and extends out from the opening at one end of the first straw 30. The outer diameter of the blade 23 is smaller than the inner diameter of the first straw 30, creating a gap between the blade 23 and the first straw 30 to facilitate the passage of smoke. This allows the blade 23 to be positioned inside the first straw 30 and the flared opening 80, attracting smoke from around the blade 23, increasing the absorption range and area, and thus improving the effectiveness of the product.

[0026] Among them, such as Figures 1-3 As shown, the suction kit includes a fixed sleeve 70 fixedly mounted on the handle 10. The fixed sleeve 70 is located on the outside of the electric knife 20. A sealing gasket is provided at the connection between the fixed sleeve 70 and the blade head 23 to provide an isolation function. A flared end 80 is fixedly provided on the side of the fixed sleeve 70 away from the handle 21. The flared end 80 is connected to the first suction tube 30 to increase the suction range.

[0027] Among them, such as Figures 1-4 As shown, the second suction tube 50 includes a tube body 51 and a suction cover 52. The suction cover 52 is located on the side of the tube body 51 near the blade head 23. The tube body 51 is a flexible and malleable tube made of soft polyvinyl chloride plastic material. The tube body 51 is made of conventional malleable material, such as soft polyvinyl chloride plastic. The tube body 51 made of this material can be bent to a certain extent and maintain the bending angle. In use, the angle of the tube body 51 pointing towards the blade head 23 can be freely adjusted as needed to achieve the best suction effect.

[0028] Among them, such as Figures 1-6As shown, the fixing assembly includes a fixing ring 90 that is slidably connected to the outer wall of the handle 10. The tube body 51 is fixedly installed at the bottom of the fixing ring 90. A circular hole is opened on the upper surface of the fixing ring 90. An insertion post 100 is slidably installed inside the circular hole. A spring is installed between the insertion post 100 and the fixing ring 90. The spring enables the insertion post 100 to automatically return to its original position and can restrict the insertion post 100 to prevent loss and ensure the stability of the installation. The spring is sleeved on the outside of the insertion post 100. Several insertion holes 110 are evenly opened on the upper surface of the handle 10. The size of the insertion post 100 is adapted to the size of the insertion hole 110. By inserting the insertion post 100 into the interior of different insertion holes 110, the position of the suction cover 52 can be adjusted. This is convenient for other medical staff to assist in the operation, and the user can also independently adjust the second suction tube 50. By setting two suction tubes, the absorption range and area are increased, effectively improving the quality of the surgery.

[0029] Example 2

[0030] The difference from Example 1 is that, as in Example 1, Figure 1 and Figure 2 As shown, both the first straw 30 and the second straw 50 are equipped with a switch valve 120 to control the opening and closing states of the first straw 30 and the second straw 50.

[0031] Among them, such as Figures 1-4 As shown, both the flare 80 and the suction hood 52 are funnel-shaped. The funnel shape can increase the suction effect, more effectively remove smoke and blood, prevent smoke from spreading in the air, facilitate surgical operation, and improve the quality of surgery.

[0032] In use, the electric telescopic component 25 is operated by the control button 60 to adjust the distance of the blade head 23 extending out of the flare 80, ensuring a certain distance between the suction tube and the blade head 23 to prevent obstruction of the surgical field. The position of the suction cover 52 is adjusted by inserting the insertion post 100 into different insertion holes 110. The angle of the tube body 51 pointing towards the blade head 23 is then adjusted as needed to achieve the best suction effect. The switch valve 120 on the suction tube is opened to start the electrosurgical unit 20 and the negative pressure suction device 40. The user holds the handle 10 and uses the blade head 23 to perform the cutting operation. Under the suction of the negative pressure suction device 40, the first suction tube 30 and the second suction tube 50 remove the smoke and a small amount of oozing blood generated by the blade head 23, allowing the user to perform cutting and suction operations independently. This avoids the drawbacks of traditional multi-person operations and prevents residual or diffused smoke due to untimely suction or lack of coordination, thus improving the quality of the surgery.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
