[0017] See Figures 1 to 2 This utility model provides a multifunctional single-stage surgical electrosurgical unit, including a single-stage electrosurgical unit 1. The single-stage electrosurgical unit 1 includes a housing 11. A retractable high-frequency electrosurgical unit 12 is provided at one end of the housing 11. An adjustment mechanism 15 is provided on the outside of the housing 11, which controls the extension and retraction of the high-frequency electrosurgical unit 12. Since the extension and retraction mechanism of the electrosurgical unit is existing technology, it will not be described in detail here. A smoke extraction channel 13 is provided inside the housing 11. A smoke extraction tube 14 communicating with the smoke extraction channel 13 is also provided on the housing 11. The other end of the smoke extraction tube 14 is connected to a negative pressure assembly. A power connection cable is provided at the rear end of the housing 11. During surgery, the single-stage electrosurgical unit 1 performs surgical cutting through the high-frequency electrosurgical unit 12. The smoke generated during the procedure is drawn into the negative pressure assembly through the smoke extraction channel 13, thereby reducing... To mitigate the interference of smoke on the surgical field of vision, in this embodiment, a suction device 2 is provided on one side of the housing 11. The suction device 2 includes a shell that is detachably snapped onto the housing 11 and a suction tube assembly disposed inside the shell. The suction device 2 is used to absorb exudate during the operation, reducing the interference of exudate on the field of vision during the surgical cutting process. The suction tube assembly includes a first pipe 23 and a second pipe 24 connected in a sleeve. The other end of the second pipe 24 is connected to a two-position three-way solenoid valve 4. The two-position three-way solenoid valve 4 connects the second pipe 24, the smoke tube 14, and the negative pressure assembly. By utilizing the one-way conduction function of the two-position three-way solenoid valve 4, independent smoke extraction and exudate absorption functions are realized. An illumination assembly 3 is provided at the end of the housing facing the first pipe 23 to facilitate local illumination during the operation.

[0018] It should be noted that in this embodiment, the diameter of the inlet end of the first pipe 23 is smaller than the diameter of the inlet end of the smoking channel 13. This design allows the large-diameter smoking channel 13 to increase the range of smoke absorption and improve the smoking effect during the operation, while the small-diameter pipe is more conducive to absorbing exudate from local tissues.

[0019] See Figure 2 The outer casing includes an outer casing body 21 and a latching part 22 disposed on one side of the outer casing body 21. The latching part 22 has a protrusion 221 at one end near the first pipe 23. The protrusion 221 extends outward from one end of the latching part 22 and is parallel to and spaced apart from one side of the outer casing body 21. The other end of the latching part 22 has a first locking block assembly 222 inside. It should be noted that a slot 111 adapted to the latching part 22 is provided on the housing 11. When the latching part 22 is inserted into the slot 111, the first locking block assembly 222 locks the latching part 22 into the slot 111, thereby realizing the detachable connection between the outer casing and the housing 11.

[0020] See Figure 3 Furthermore, in this embodiment, the first locking block assembly 222 includes a tongue lock 2221 partially disposed inside the latching portion 22 and slidably connected to the latching portion 22. The outer end of the tongue lock 2221 extends through one end of the latching portion 22, and the other end of the tongue lock 2221 is provided with a first spring 2222. One end of the first spring 2222 abuts against the tongue lock 2221, and the other end abuts against the latching portion 22. An unlocking button 2223 is fixedly disposed on one side of the tongue lock 2221. The unlocking button 2223 has an L-shaped structure, with one end connected to the tongue lock 2221 and the other end located in the outer shell body. Inside 21, and extending out of the outer shell through one side of the outer shell body 21, by pressing the unlock button 2223, the tongue lock 2221 is pushed to slide inside the latch part 22, and at the same time the first spring 2222 is compressed, thereby realizing the unlocking of the latch part 22 and the slot 111; in addition, in order to facilitate the quick engagement of the latch part 22 and the slot 111, the portion of the tongue lock 2221 extending out of the latch part 22 when the first spring 2222 is in its natural state is set as an angle. As those skilled in the art will understand, the quick engagement and locking of the latch part 22 and the slot 111 can be automatically realized by directly pressing the outer shell.

[0021] See Figure 3 and Figure 4Furthermore, a slider 25 is provided on one side of the first pipe 23, and a groove 26 adapted to the slider 25 is provided inside the outer shell body 21. A second spring 27 is also provided inside the outer shell body 21. One end of the second spring 27 abuts against the slider 25, and the other end abuts against the outer shell body 21. The second spring 27 is a tension spring, used to drive the first pipe 23 into the outer shell body 21. It can be understood that when the second spring 27 is in its natural state, the first pipe 23 is located inside the outer shell body 21. However, a push handle mechanism 29 is provided on one side of the first pipe 23. In further embodiments, the push handle mechanism 29 includes a push rod 291 with one end fixedly connected to the slider 25. The end of the push rod 291 away from the slider 25 extends out of the outer shell and connects to a push block 292. The outer shell is provided with an opening groove 211 to avoid the sliding of the push rod 291. In use, the finger pushes the push block 292, causing the push rod 291 to slide along the opening groove 211. This allows the first pipe 23 to extend out of the outer casing 21 against the elastic force of the second spring 27. To ensure that the first pipe 23 can be locked and not retracted after extending out of the outer casing 21, a second locking block assembly 28 is provided on the outer casing 21, and a locking groove 251 adapted to the second locking block assembly 28 is provided on the slider 25. Furthermore, the second locking block assembly 28 includes a lock head 281 adapted to the locking groove 251, and a pull rod 282 is fixedly provided at the end of the lock head 281 away from the slider 25. The pull rod 282 passes through the outer shell, and a third spring 283 is sleeved on the pull rod 282. One end of the third spring 283 abuts against the lock head 281, and the other end abuts against the outer shell body 21. It should be noted that in order to facilitate the first pipe 23 to be locked in place directly and quickly by pushing the push block 292, a slope is also provided on one side of the lock head 281. As those skilled in the art will understand, the inclination angle of the slope is set towards the sliding direction of the first pipe 23.

[0022] See Figure 4 Since the unlocking operation of the second locking block assembly 28 is achieved by pulling the lever 282 upward, causing the lock head 281 to disengage from the insertion limit of the lock groove 251, thereby realizing the retraction and unlocking of the first pipe 23, in some embodiments, an anti-slip structure can be provided on the protruding part of the lever 282, or it can be set into an irregular shape to facilitate the fingers to pull the lever 282. In this embodiment, preferably, a pull ring 284 is provided at one end of the lever 282, wherein the pull ring 284 is rotatably connected to the lever 282, and the radius of the arc part of the pull ring 284 is slightly larger than the radius of the lever 282. This facilitates the storage of the pull ring 284 and saves space. By setting the pull ring 284, unlocking is more effortless.

[0023] See Figure 1Furthermore, in this embodiment, the lighting component 3 includes a plurality of LED beads disposed at one end of the housing and a switch button 31 disposed on one side of the housing. In this embodiment, there are 5 LED beads, which are evenly distributed around the first pipe 23. By setting the lighting component 3, local lighting during the operation is facilitated. The switch button 31 is used to control the working state of the lighting component 3.

[0024] In addition, in this embodiment, the switch for controlling the two-position three-way solenoid valve 4 can be located on the solenoid valve body or on the housing 11 of the single-stage electrosurgical knife 1, so as to facilitate the switching and conduction of the solenoid valve at any time. The specific method can be determined according to the connection method of the two-position three-way solenoid valve 4 and the single-stage electrosurgical knife 1.

[0025] Usage process: Without needing to remove the permeation fluid, the suction device 2 can be removed first. Surgical cutting can be achieved by using a single-stage electrosurgical unit 1 in conjunction with the smoke channel 13, and the smoke can be removed. In situations where ambient light is insufficient, the suction device 2 can be assembled while the suction tube assembly is retracted. At this stage, the suction device 2 is used for lighting. It should be noted that retracting the suction tube assembly reduces the obstruction of light by the first pipe 23, thus improving the lighting function of the suction device 2. When surgical cutting and permeation fluid aspiration are required, the aspiration and cutting functions can be switched by self-contracting the high-frequency electrosurgical unit 12 or the first channel 23, and the two functions do not interfere with each other after contraction, thereby improving work efficiency.

[0026] In summary, the multifunctional single-stage surgical electrosurgical unit of the present invention, as described in the above embodiments, has a suction device installed on one side of the single-stage electrosurgical unit, and a two-position three-way solenoid valve installed at one end of the second pipe and the smoke tube of the suction device. By utilizing the one-way opening function of the two-position three-way solenoid valve, the smoke suction function and the permeate suction function of the single-stage electrosurgical unit are separated. By setting the inlet diameter of the smoke suction channel to be larger than the inlet diameter of the first pipe, the suction capacity of each is improved. In addition, an illumination component is installed on the outer shell of the suction device for local real-time illumination during surgery.
