[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0044] In the description of this utility model, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0045] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0046] Reference Figures 1 to 7 As shown in the figure, this utility model embodiment proposes an electrosurgical eraser, which includes a base 100 and a first erasing assembly 200.

[0047] In this embodiment, the base 100 includes a bottom wall and two opposite, spaced-apart side walls. The bottom wall provides the main support for the first erasing assembly 200. The two side walls are located on opposite sides of the bottom wall, forming a cavity between them. After the first erasing assembly 200 removes residual tissue from the electrosurgical surface, the detached tissue falls into the cavity. After use, the tissue in the cavity needs to be cleaned. Therefore, a collection component 800 is typically installed in the cavity. The collection component 800 can collect the tissue centrally, making it easier to clean.

[0048] The first erasing assembly 200 includes a first erasing blade 210 and a second erasing blade 220 arranged opposite to each other and spaced apart. A first erasing groove is formed between the first erasing blade 210 and the second erasing blade 220. Both the first erasing blade 210 and the second erasing blade 220 are elastically connected to the base 100. Because the first erasing blade 210 and the second erasing blade 220 are elastically connected to the base 100, when the insertion cross-sectional size of the electrosurgical knife is larger than the groove width of the first erasing groove, the electrosurgical knife will open the first erasing groove, and the first erasing blade 210 and the second erasing blade 220 will also undergo elastic deformation, making the first erasing groove wider. At the same time, the first erasing blade 210 will also be in close contact with the outer surface of the electrosurgical knife. During the insertion of the electrosurgical knife, the first erasing blade 210 and the second erasing blade 220 scrape away the dirt on the surface of the electrosurgical knife. It should be noted that the surface of the electrosurgical knife is generally cylindrical or flat cylindrical, for example, having two opposite and flat opposing planes and two opposite curved surfaces. The two planes and the two curved surfaces constitute the complete outer surface of the electrosurgical knife.

[0049] The first wiping assembly 200 is configured such that: when the electrosurgical unit is inserted into the first wiping groove, the first wiping blade 210 and the second wiping blade 220 undergo elastic deformation and wipe the surface of the electrosurgical unit; when the electrosurgical unit is withdrawn from the first wiping groove, the first wiping blade 210 and the second wiping blade 220 undergo elastic deformation and wipe the surface of the electrosurgical unit. During the insertion and withdrawal of the electrosurgical unit, both the first wiping blade 210 and the second wiping blade 220 are in close contact with the outside of the electrosurgical unit, enabling both wiping blades 210 and 220 to scrape away dirt from the surface of the electrosurgical unit, achieving dual cleaning and resulting in a higher cleaning effect.

[0050] It is understandable that the automatic cleaning of the electrosurgical unit is completed when it is inserted into and withdrawn from the first cleaning slot, resulting in higher cleaning efficiency. Furthermore, the first and second wiping blades 210 and 220 can directly scrape away dirt from the surface of the electrosurgical unit, further enhancing its cleaning effect.

[0051] In addition, refer to Figure 8 and Figure 9 As shown, at least one of the first wiper blade 210 and the second wiper blade 220 is adjustablely connected to the base 100 to adjust the distance between the first wiper blade 210 and the second wiper blade 220. The first wiper blade 210 has an oblong hole in a direction away from the second wiper blade 220. The base 100 has a threaded hole. A bolt is inserted into the oblong hole and locked in place with the threaded hole, clamping the first wiper blade 210 to the base 100. After the bolt is loosened, the distance between the first wiper blade 210 and the second wiper blade 220 can be adjusted through the oblong hole. As in some other embodiments, the second wiper blade 220 may also have an oblong hole, and the base 100 may have a threaded hole corresponding to the second wiper blade 220. A bolt is inserted into the oblong hole and locked in place with the threaded hole, clamping the second wiper blade 220 to the base 100.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, a second erasing group 300 is also included, comprising a third erasing plate 310 and a fourth erasing plate 320 arranged opposite to and spaced apart, with a second erasing groove formed between the third erasing plate 310 and the fourth erasing plate 320, and both the third erasing plate 310 and the fourth erasing plate 320 being elastically connected to the base 100; wherein, the first erasing group 200, the second erasing group 300, and the base 100 are arranged sequentially along a first direction, and the second erasing groove and the first erasing groove are aligned along the first direction; wherein, the second erasing group 300 is configured such that: when the electrosurgical knife is inserted into the first erasing groove and the second erasing groove along the first direction, the third erasing plate 310 and the fourth erasing plate 320 undergo elastic deformation and erase the surface of the electrosurgical knife; when the electrosurgical knife is withdrawn from the second erasing groove, the third erasing plate 310 and the fourth erasing plate 320 undergo elastic deformation and erase the surface of the electrosurgical knife.

[0053] It is understandable that the second erasing group 300 and the first erasing group 200 work together to clean the surface of the electrosurgical unit, resulting in a better cleaning effect and greater convenience for medical personnel. In this embodiment, the electrosurgical unit is inserted sequentially into the first erasing groove and the second erasing groove along the insertion direction to achieve cleaning of the electrosurgical unit's surface.

[0054] Reference Figure 2 , Figure 3 and Figure 4As shown, in some specific embodiments of this utility model, it also includes an elastic first wall group 400 and an elastic second wall group 500. The first wall group 400 and the second wall group 500 are sequentially connected to the base 100. The first wall group 400 is connected to the first erasing group 200, and the second wall group 500 is connected to the second erasing group 300. The bending directions of the first wall group 400 and the second wall group 500 are opposite.

[0055] It is understandable that the first erasing group 200 undergoes elastic deformation through the first wall group 400, and the second erasing group 300 undergoes elastic deformation through the second wall group 500. Furthermore, since the first wall group 400 and the second wall group 500 are interconnected, when the first wall group 400 undergoes elastic deformation, it will affect the second wall group 500, causing the second wall group 500 to also undergo elastic deformation. This results in a larger deformation range of the second erasing groove, meaning that the third wiping blade 310 and the fourth wiping blade 320 exert greater force against the surface of the electrosurgical unit, leading to a better erasing effect.

[0056] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the end of the first erasing group 200 away from the first wall group 400 is disposed toward the base 100, and the end of the second erasing group 300 away from the second wall group 500 is disposed in a direction away from the base 100.

[0057] It should be noted that during the insertion of the electrosurgical unit, the angle between the first erasing group 200 and the electrosurgical unit is either an acute angle or an obtuse angle. During the withdrawal of the electrosurgical unit, the angle between the first erasing group 200 and the electrosurgical unit is either an acute angle or an obtuse angle. When the angle between the first erasing group 200 and the electrosurgical unit is an acute angle, the erasing effect of the first erasing group 200 is lower than that when the angle between the first erasing group 200 and the electrosurgical unit is an obtuse angle.

[0058] Based on this, the orientations of the first erasing group 200 and the second erasing group 300 are set to opposite directions. When the angle between the first erasing group 200 and the electrosurgical unit is an acute angle, the angle between the second erasing group 300 and the electrosurgical unit is an obtuse angle. The second erasing group 300 plays the main erasing role, while the first erasing group 200 plays an auxiliary erasing role. The second erasing group 300 has a better cleaning effect on the electrosurgical unit. When the angle between the first erasing group 200 and the electrosurgical unit is an obtuse angle, the angle between the second erasing group 300 and the electrosurgical unit is an acute angle. The first erasing group 200 plays the main erasing role, while the second erasing group 300 plays an auxiliary erasing role. The first erasing group 200 has a better cleaning effect on the electrosurgical unit.

[0059] In this embodiment, when the electrosurgical unit is inserted into the electrosurgical unit, the angle between the first erasing group 200 and the electrosurgical unit is an acute angle, and the angle between the second erasing group 300 and the electrosurgical unit is an obtuse angle; when the electrosurgical unit is withdrawn from the electrosurgical unit, the angle between the first erasing group 200 and the electrosurgical unit is an obtuse angle, and the angle between the second erasing group 300 and the electrosurgical unit is an acute angle; thus, during the insertion and withdrawal of the electrosurgical unit, either the first erasing group 200 or the second erasing group 300 can maintain a good erasing effect on the electrosurgical unit, resulting in a better cleaning effect of the electrosurgical unit.

[0060] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the first wall assembly 400 protrudes in a direction away from the first erasing groove, and the second wall assembly 500 protrudes toward the first erasing groove.

[0061] In this embodiment, refer to Figure 6 As shown, when the electrosurgical unit is inserted into the first and second erasing grooves, the end of the first wall assembly 400 away from the second wall assembly 500 deforms toward the side where the base 100 is located, i.e., it has a first torque that rotates toward the side where the base 100 is located. Under the action of the first torque, the first erasing groove of the first erasing assembly 200 will expand, and the cleaning effect of the first wiping blade 210 and the second wiping blade 220 on the surface of the electrosurgical unit will decrease. At the same time, when the first torque is transmitted to the second wall assembly 500, the first torque will cause the end of the second wall assembly 500 away from the base 100 to rotate toward the cavity in the middle of the base 100. At this time, the second wall assembly 500 drives the second erasing groove of the second erasing assembly 300 to shrink, and causes the end of the third wiping blade 310 and the fourth wiping blade 320 forming the second erasing groove to rotate toward the base 100, thereby making the third wiping blade 310 and the fourth wiping blade 320 closely adhere to the surface of the electrosurgical unit, so as to improve the cleaning effect of the third wiping blade 310 and the fourth wiping blade 320 on the electrosurgical unit.

[0062] Conversely, refer to Figure 7 As shown, when the electrosurgical unit is withdrawn from the first and second erasing grooves, the end of the second wall assembly 500 away from the base 100 will rotate outward from the base 100 and have a second torque for rotating outward from the base 100. Under the action of the second torque, the second erasing groove of the second erasing assembly 300 expands, and the cleaning effect of the third wiping blade 310 and the fourth wiping blade 320 on the surface of the electrosurgical unit decreases. At the same time, the second torque is transmitted to the first wall assembly 400, and the first wall assembly 400 will have a tendency to rotate in the direction away from the base 100, which will cause the first erasing groove to expand. The first wiping blade 210 and the second wiping blade 220 will be in close contact with the surface of the electrosurgical unit to improve the cleaning effect of the first wiping blade 210 and the second wiping blade 220 on the electrosurgical unit.

[0063] In the above process, through the elastic deformation of the first wall assembly 400 and the second wall assembly 500, the deformations of the first and second erasing grooves are opposite. When one of them has an expanding tendency, the other has a shrinking tendency, ensuring that both maintain a consistent cleaning effect on the electrosurgical unit. Furthermore, in this embodiment, when the second erasing groove has a shrinking tendency, the angle between the second erasing groove and the electrosurgical unit is acute; when the first erasing groove has a shrinking tendency, the angle between the first erasing groove and the electrosurgical unit is also acute, further improving the cleaning effect of the first and second erasing grooves on the electrosurgical unit surface.

[0064] Reference Figure 4 As shown, in some specific embodiments of this utility model, the distance between the first erasing group 200 and the second erasing group 300 along the first direction is L, and the electrosurgical excision satisfies: L≤10mm. In this embodiment, the first direction is the height direction of the cavity in the base 100. The smaller the distance between the first erasing group 200 and the second erasing group 300 along the first direction, the easier it is for the electrosurgical excision to pass through the first erasing groove and the second erasing groove in sequence. Furthermore, the fewer the cleaning dead zones between the first erasing groove and the second erasing groove, the better the cleaning effect of the electrosurgical excision to the first erasing groove and the second erasing groove on the electrosurgical excision.

[0065] Reference Figure 3 As shown, in some specific embodiments of this utility model, a housing 600 is also included. The housing 600 is connected to the base 100 and sleeved on the first erasing assembly 200. The inner circumferential surface of the housing 600 is spaced apart from the first erasing assembly 200. The housing 600 has a clearance groove, and the clearance groove, the first erasing groove, and the second erasing groove are aligned along a first direction. It is worth understanding that by sleeved on the base 100, the appearance of the base 100 is improved, thereby enhancing the product's performance. The clearance groove is used for inserting or withdrawing the power supply knife into the first erasing groove and the second erasing groove. The inner circumferential surface of the housing 600 is spaced apart from the first erasing assembly 200, the first wall assembly 400, the second erasing assembly 300, and the second wall assembly 500. When the first wall assembly 400 and the second wall assembly 500 undergo elastic deformation, the housing 600 will not interfere with the first wall assembly 400 and the second wall assembly 500, making its use more reliable.

[0066] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, the base 100 includes a first guide portion 110, and the outer shell 600 includes a first shell 610, a second guide portion disposed on the first shell 610, and a second shell 620. The first shell 610 is slidably connected to the first guide portion 110 and can be stopped by the first guide portion 110. The second shell 620 is slidably connected to the second guide portion and can be stopped by the base 100.

[0067] In this embodiment, the base 100 further includes a first stop block 120 disposed on the first guide portion 110. The first stop block 120 stops the movement of the first housing 610, allowing the first housing 610 to be spaced apart from the first erasing assembly 200, the first wall assembly 400, the second erasing assembly 300, and the second wall assembly 500. Due to the stop of the first stop block 120, when the second housing 620 is slidably connected to the second guide portion, a portion of the base 100 extends between the first wall assembly 400 and the second wall assembly 500. The second housing 620 and the extended portion of the base 100 are stopped, allowing the second housing 620 to move away from the first erasing assembly 200 and the first wall assembly 400. 0. The second erasing group 300 and the second wall group 500 are spaced apart. The second housing 620 and the base 100 stop each other, causing the second guide portion to limit and fix the first housing 610 along the length direction of the first guide portion 110. The first limiting block also limits and fixes the first housing 610 along the length direction of the first guide portion 110. The second guide portions are respectively located on opposite sides of the first housing 610 along the length direction of the first guide portion 110, thus fixing the first housing 610. The first housing 610 and the second housing 620 can be spaced apart from the first erasing group 200, the first wall group 400, the second erasing group 300, and the second wall group 500. The second guide portion is located along the height direction of the first housing 610. When the outer shell 600 needs to be removed, the second housing 620 can be removed along the second guide portion to separate the first housing 610 from the base 100.

[0068] Refer to 4 and Figure 5 As shown, in some specific embodiments of this utility model, a disinfection layer 700 is also provided in the first wiping group 200. The disinfection layer 700 is provided in the first wiping pad 210 and / or the second wiping pad 220. The disinfection layer 700 can absorb disinfectant. The disinfection layer 700 is configured such that when the electrosurgical knife is in the first wiping groove, the disinfection layer 700 is squeezed and the disinfectant is squeezed out to the surface of the electrosurgical knife.

[0069] In this embodiment, the disinfection layer 700 is used to absorb a certain amount of disinfectant. When the electrosurgical knife is inserted into the first wiping groove, causing the first wiping pad 210 and the second wiping pad 220 to undergo a certain elastic deformation, the electrosurgical knife will squeeze the disinfection layer 700 and squeeze out the disinfectant within the disinfection layer 700, thus achieving disinfection and cleaning of the electrosurgical knife during the wiping process, making the cleaning of the electrosurgical knife more convenient. In addition, the disinfection layer 700 can also be provided on the surface of the third wiping pad 310 and / or the fourth wiping pad 320.

[0070] Refer to 4 and Figure 5As shown, in some specific embodiments of this utility model, the first wiping pad 210 has a sandwich layer 211 and a communication port 212 connecting the sandwich layer 211 and the outer surface of the first wiping pad 210. The disinfection layer 700 is disposed in the sandwich layer 211 and is configured such that the disinfectant squeezed out by the disinfection layer 700 can pass through the communication port 212 to the outer surface of the first wiping pad 210.

[0071] In this embodiment, the first wiping pad 210 has a sandwich layer 211, and the disinfection layer 700 is disposed within the sandwich layer 211. The sandwich layer 211 has a connecting port 212 that communicates with the outer surface of the first wiping pad 210. When the first wiping pad 210 undergoes elastic deformation, the disinfection layer 700 will be compressed, thereby squeezing out disinfectant. The disinfectant flows out through the connecting port 212 to the surface of the first wiping pad 210 to achieve disinfection of the first wiping pad 210. The first wiping pad 210 also has a replacement port, which is located on the side of the sandwich layer 211 away from the first wiping groove and communicates with the sandwich layer 211. The disinfection layer 700 can be replaced through the replacement port or disinfectant can be injected. In addition, the second wiping pad 220, the third wiping pad 310 and / or the fourth wiping pad 320 may also have a disinfection layer 700.

[0072] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, a recycling component 800 is also included. The recycling component 800 has a recycling port, which is aligned vertically with the first erasing groove. The recycling component 800 can be separated from the base 100.

[0073] In this embodiment, the retrieval port is located at the top of the retrieval component 800, which is positioned below the first wiping groove. When the electrosurgical unit performs wiping, the tissue on the surface of the electrosurgical unit will fall into the retrieval component 800 under gravity and be collected and processed by the retrieval component 800. The outer casing 600 has a clearance opening through which the retrieval component 800 is inserted into the base 100.

[0074] Reference Figure 3 As shown, in some specific embodiments of this utility model, the electric knife wiper also includes a limiting member 130. The limiting member 130 is connected to the base 100 and is used to limit the elastic deformation angle of the first wiping piece 210, so that the deformation range of the first wiping piece 210 is within a controllable range, avoiding the first wiping piece 210 from deforming too much, resulting in too little contact pressure between the first wiping piece 210 and the electric knife, or causing the third wiping piece 310 to deform too much.

[0075] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
