When the high-frequency high-voltage current generated by the tip of the effective electrode contacts the body, the body tissues are heated to be separated and coagulated, so that the purpose of cutting and hemostasis is achieved.

[0003] At present, a surgical electric knife auxiliary suction device is disclosed in Chinese Patent No. CN117481781, published on February 2, 2024. The device includes a smoke suction device, a smoke collecting cylinder is installed above the smoke suction device, a smoke suction pipe is communicated in the smoke collecting cylinder, a surgical electric knife is installed at one end of the smoke suction pipe away from the smoke collecting cylinder, a suction force adjusting control button is installed on the outer wall of the surgical electric knife, a suction force adjusting auxiliary mechanism is arranged in the smoke suction pipe, and a smoke disinfection mechanism is arranged in the smoke collecting cylinder. The suction force adjusting auxiliary mechanism is used to assist the surgical electric knife to control the suction force adjusting control button. The smoke disinfection mechanism is used to disinfect the absorbed smoke.

[0004] When the surgical electric knife is started, the medical staff often needs to actively start the smoke suction device, so that the smoke suction device can be started at the same time when the surgical electric knife works. Meanwhile, the medical staff also needs to actively close the smoke suction device when the surgical electric knife stops working. The whole use process is very inconvenient, which brings great trouble to the operation of the medical staff. SUMMARY

[0005] The purpose of the present application is to provide a surgical electric knife smoke suction assembly convenient to synchronously open and close, which can conveniently open and close the smoke suction pipe following the surgical electric knife.

[0006] The above technical purpose of the present application is realized by the following technical scheme: a surgical electric knife smoke suction assembly convenient to synchronously open and close, comprising a surgical electric knife, a smoke suction pipe connected to one end of the surgical electric knife, and a suction device arranged at the end of the smoke suction pipe away from the surgical electric knife, characterized in that: a monitoring relay electrically connected to the surgical electric knife and used to monitor the power of the surgical electric knife is further included, a signal controller is connected to the monitoring relay, an electromagnetic valve is installed on the smoke suction pipe, and a wireless signal receiver for controlling the opening and closing of the electromagnetic valve after receiving the signal of the signal controller is connected to the electromagnetic valve.

[0007] When the monitoring relay monitors that the power of the surgical electrotome is increased (in the working state), the signal controller connected with the monitoring relay transmits a signal to the wireless signal receiver where the electromagnetic valve is located, and the wireless signal receiver controls the electromagnetic valve to open the smoke suction pipe after receiving the signal, and the smoke suction pipe generates suction force for absorbing smoke;

[0008] When the monitoring relay monitors that the power of the surgical electrotome is reduced (in the non-working state), the signal controller connected with the monitoring relay transmits a signal to the wireless signal receiver where the electromagnetic valve is located, and the wireless signal receiver controls the electromagnetic valve to close the smoke suction pipe after receiving the signal, and the smoke suction pipe is closed.

[0009] By adopting the above technical scheme, the opening and closing state of the surgical electrotome can be detected by monitoring the power through the detection relay, and the electromagnetic valve is controlled by the signal controller and the wireless signal receiver, so that the electromagnetic valve is opened and closed following the opening and closing of the surgical electrotome, and finally the smoke suction pipe can be opened and closed following the surgical electrotome.

[0010] The further setting of the present application is that the valve body of the electromagnetic valve is a three-way valve, and a smoke suction cover for sucking air in the operating room is arranged on the valve body end of the electromagnetic valve.

[0011] By adopting the above technical scheme, when the surgical electrotome is closed, the electromagnetic valve can close the suction of the smoke suction pipe to the position of the surgical electrotome, and at the same time, the electromagnetic valve opens the suction of the smoke suction cover, so that the air in the operating room is continuously absorbed and purified.

[0012] The further setting of the present application is that the smoke suction pipe is wrapped around the tool head of the surgical electrotome at one end of the surgical electrotome, and a cleaning piece for softening the scab and carbonized tissue on the surface of the tool head is arranged on the smoke suction pipe.

[0013] By adopting the above technical scheme, when the surgical electrotome is used, there will be scab and carbonized tissue on the tool head of the surgical electrotome, and at this time, the scab and carbonized tissue need to be cleaned, and the cleaning piece can be used to pass physiological saline into the smoke suction pipe until the physiological saline reaches the position of the tool head, and at this time, the physiological saline can be used to soften the scab and carbonized tissue on the surface of the tool head, and the softened scab and carbonized tissue can be conducive to the subsequent scraping of the scab and carbonized tissue on the surface of the tool head by medical staff.

[0014] The further setting of the present application is that the cleaning piece comprises a liquid supply bin containing physiological saline, a liquid supply pipe connected with the liquid supply bin at one end and connected with the smoke suction pipe at the other end, a liquid supply pump arranged on the liquid supply pipe, and a liquid supply valve arranged on the liquid supply pipe, and the liquid supply pipe is arranged on the smoke suction pipe between the electromagnetic valve and the surgical electrotome.

[0015] By adopting the technical scheme, when the surgical electrotome stops and the eschar and carbonized tissue on the knife head need to be cleaned, the electromagnetic valve first closes the smoke suction pipe following the surgical electrotome, then the infusion pump is started and the infusion valve is opened, at this time, the physiological saline in the liquid supply bin can be introduced into the smoke suction pipe, then the physiological saline can flow to the knife head position and be used to soften the eschar and carbonized tissue on the surface of the knife head; meanwhile, the continuously delivered physiological saline can also be used to cool the knife head.

[0016] The further arrangement of the present application is that the suction device comprises a shell, a motor body installed in the shell, a volute with an impeller inside and connected to the motor body, a purification component arranged on one side of the shell and used for purifying smoke, and the smoke suction port of the volute is connected to the smoke suction pipe.

[0017] By adopting the technical scheme, the rotation of the impeller in the volute driven by the motor body can generate suction in the smoke suction pipe, and the suctioned smoke is introduced into the purification component for purification.

[0018] The further arrangement of the present application is that the purification component comprises an adsorption chamber with physiological saline at the bottom and arranged on one side of the shell, an exhaust pipe arranged at the air outlet of the volute and extending below the water surface of the physiological saline, a filter chamber arranged on the side of the adsorption chamber away from the shell and communicating with the upper side of the adsorption chamber, and a filter screen group arranged in the filter chamber.

[0019] By adopting the technical scheme, the smoke discharged from the exhaust pipe first enters the adsorption chamber, and the smoke introduced into the physiological saline in the adsorption chamber reacts with the physiological saline as an electrolyte solution to generate carbonic acid, thereby adsorbing carbon dioxide gas in the smoke, which is conducive to maintaining a clear surgical field and reducing the operation risk.

[0020] Since a part of the physiological saline remains in the smoke suction pipe after the physiological saline is delivered in the smoke suction pipe, when the suction of the smoke suction pipe is opened, the part of the physiological saline remaining in the smoke suction pipe can be supplemented into the adsorption chamber through the exhaust pipe, thereby making up the volatilization and consumption of the physiological saline in the adsorption chamber; at this time, efficient use of the physiological saline remaining in the smoke suction pipe can be achieved.

[0021] The further arrangement of the present application is that the filter screen group comprises two layers of activated carbon filter screens and a core ULPA filter screen between the two layers of activated carbon filter screens.

[0022] By adopting the technical scheme, the two layers of activated carbon filter screens and the core ULPA filter screen between the two layers of activated carbon filter screens can efficiently adsorb harmful substances in the smoke, thereby reducing the harm to medical staff.

[0023] The further arrangement of the present application is that the motor body is a brushless motor.

[0024] By adopting the above technical scheme, since the brushless motor is more silent, noise pollution in the operating room can be effectively reduced, and the smooth operation is facilitated.

[0025] The shell is further provided with an acoustic cotton layer on the inner wall of the circumferential side.

[0026] By adopting the above technical scheme, the sound generated by the motor body can be absorbed by the acoustic cotton layer, thereby further reducing the noise pollution in the operating room.

[0027] The beneficial effects of the present application are as follows: first, during the use of the surgical electrotome, the detection relay detects the opening and closing state of the surgical electrotome by monitoring the power, and then the signal controller and the wireless signal receiver control the electromagnetic valve, so that the electromagnetic valve opens and closes in conjunction with the opening and closing of the surgical electrotome, and finally the smoke suction pipe opens and closes in conjunction with the surgical electrotome;

[0028] The valve body of the electromagnetic valve is a three-way valve, when the surgical electrotome is closed, the electromagnetic valve closes the suction of the smoke suction pipe at the position of the surgical electrotome, and at the same time, the electromagnetic valve opens the suction at the position of the smoke cover, thereby continuously absorbing and purifying the air in the operating room;

[0029] At the same time, after the surgical electrotome is used, there will be eschar and carbonized tissue on the head of the surgical electrotome, at this time, the eschar and carbonized tissue need to be cleaned, the electromagnetic valve first closes the smoke suction pipe in conjunction with the surgical electrotome, and then starts the infusion pump and opens the infusion valve, at this time, the physiological saline in the liquid supply bin flows into the smoke suction pipe, and then the physiological saline flows to the position of the head to soften the eschar and carbonized tissue on the surface of the head; at the same time, the continuously delivered physiological saline can also be used to cool the head, and the softened eschar and carbonized tissue can be conducive to the subsequent scraping of the eschar and carbonized tissue on the surface of the head by medical staff, wherein the physiological saline on the head needs to be wiped off after cleaning the eschar and carbonized tissue on the surface of the head, so as to avoid the influence of the physiological saline on the use of the head;

[0030] The smoke gas discharged from the exhaust pipe first enters the adsorption chamber, and after the smoke gas enters the physiological saline in the adsorption chamber, the physiological saline as an electrolyte solution can react with carbon dioxide gas to generate carbonic acid, thereby adsorbing the carbon dioxide gas in the smoke gas, and finally it is conducive to maintaining a clear surgical field and reducing the operation risk; at the same time, since a part of the physiological saline still remains in the smoke suction pipe after the physiological saline is delivered in the smoke suction pipe, when the suction of the smoke suction pipe is opened, the part of the physiological saline remaining in the smoke suction pipe can be supplemented into the adsorption chamber through the exhaust pipe, thereby making up the volatilization and consumption of the physiological saline in the adsorption chamber; at this time, the efficient use of the physiological saline remaining in the smoke suction pipe can be realized.

Detailed Implementation

[0035] The technical solutions in the embodiments will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] A smoking component for a surgical electrosurgical unit that facilitates simultaneous opening and closing, as shown in the following figure. Figure 1 The surgical electrosurgical unit 1 with easy synchronous opening and closing includes a surgical electrosurgical unit 1, a smoke tube 2, a suction device 3, and a monitoring relay 4. One end of the smoke tube 2 is connected to the surgical electrosurgical unit 1, and the other end is connected to the suction device 3. The smoke tube 2 is located at one end of the surgical electrosurgical unit 1 and is wrapped around the blade of the surgical electrosurgical unit 1. The suction device 3 provides suction to the smoke tube 2, thereby sucking up the smoke generated at the blade position through the smoke tube 2.

[0037] Reference Figure 1The monitoring relay 4 is electrically connected to the surgical electrosurgical knife 1 and is used to monitor the power of the surgical electrosurgical knife 1. The monitoring relay 4 is electrically connected to the signal controller 41. The solenoid valve 21 is installed and fixed on the smoking tube 2. The valve body of the solenoid valve 21 is a three-way valve. At the same time, a smoking hood 212 for drawing air from the operating room is provided at the valve body end of the solenoid valve 21. The solenoid valve 21 is also connected to a wireless signal receiver 211 for receiving the signal from the signal controller 41 and controlling the opening and closing of the solenoid valve 21.

[0038] The specific working state is as follows: When the monitoring relay 4 detects that the power of the surgical scalpel 1 has increased (in working state), the signal controller 41 connected to the monitoring relay 4 transmits a signal to the wireless signal receiver 211 where the solenoid valve 21 is located. After receiving the signal, the wireless signal receiver 211 controls the solenoid valve 21 to open the smoke tube 2 leading to the position of the surgical scalpel 1. The smoke tube 2 generates suction to absorb the smoke generated at the position of the surgical scalpel 1.

[0039] When the monitoring relay 4 detects that the power of the surgical electrosurgical unit 1 has decreased (is in a non-working state), the signal controller 41 connected to the monitoring relay 4 transmits a signal to the wireless signal receiver 211 where the solenoid valve 21 is located. After receiving the signal, the wireless signal receiver 211 controls the solenoid valve 21 to close the smoke tube 2 leading to the position of the surgical electrosurgical unit 1. The smoke tube 2 leading to the position of the surgical electrosurgical unit 1 is closed, and the smoke hood 212 is opened instead, so as to continue to draw air from the operating room.

[0040] Reference Figure 1 , Figure 2 The smoking tube 2 is also equipped with a cleaning component 5. The cleaning component 5 allows saline solution to be introduced into the smoking tube 2 to the blade head, which can then be used to soften eschar and carbonized tissue on the blade head surface. This cleaning component 5 includes a supply chamber 51, an infusion tube 52, an infusion pump 53, and an infusion valve 54. The supply chamber 51 contains saline solution, while the infusion tube 52 is connected to the supply chamber 51 at one end and to the smoking tube 2 at the other end. The infusion tube 52 is located on the smoking tube 2 between the solenoid valve 21 and the surgical electrosurgical unit 1. The infusion pump 53 and the infusion valve 54 are fixedly installed on the infusion tube 52, and the infusion tube 52 can be controlled by the infusion pump 53 and the infusion valve 54.

[0041] Reference Figure 1 , Figure 2 The suction device 3 includes a housing 31, a motor body 32, a volute 33, and a purification component 34. A sound-absorbing cotton layer 311 is bonded and fixed to the inner wall of the housing 31. The motor body 32 is fixedly installed inside the housing 31 and is a brushless motor. The volute 33 is fixedly installed on the motor body 32 and has an impeller inside. The impeller can be driven to rotate by the motor body 32. The air inlet of the volute 33 is connected to the smoke extraction pipe 2.

[0042] Referring to Figure 1 、 Figure 2 The purifying member 34 is arranged on one side of the shell 31 and is used for purifying flue gas. The purifying member 34 comprises an adsorption chamber 341, an exhaust pipe 342, a filter chamber 343, and a filter screen group 344. The adsorption chamber 341 is fixed on one side of the shell 31 and contains physiological saline at the bottom. The exhaust pipe 342 is connected to the air outlet of the volute 33 at one end and extends to a position below the water surface of the physiological saline at the other end. The filter chamber 343 is fixed on the side of the adsorption chamber 341 away from the shell 31 and is communicated with the adsorption chamber 341 at the top. The bubbles generated from the liquid surface of the physiological saline are discharged from the filter chamber 343. The filter screen group 344 is arranged in the filter chamber 343. The filter screen group 344 comprises two layers of activated carbon filter screens 3441 and a core ULPA filter screen 3442 between the two layers of activated carbon filter screens 3441.

[0043] Principle: first, in the use of the surgical electrotome 1, the detection relay is used to detect the opening and closing state of the surgical electrotome 1 by monitoring the power, and then the signal controller 41 and the wireless signal receiver 211 are used to control the electromagnetic valve 21, so that the electromagnetic valve 21 is opened and closed following the opening and closing of the surgical electrotome 1, and finally the suction pipe 2 on the surgical electrotome 1 can be opened and closed following the surgical electrotome 1.

[0044] The valve body of the electromagnetic valve 21 is a three-way valve. When the surgical electrotome 1 is closed, the electromagnetic valve 21 can close the suction of the position of the surgical electrotome 1 by the suction pipe 2, and open the suction of the position of the suction hood 212, so as to continuously absorb and purify the air in the operating room.

[0045] At the same time, after the use of the surgical electrotome 1, there will be eschar and carbonized tissue on the head of the surgical electrotome 1, which needs to be cleaned. The electromagnetic valve 21 first closes the suction pipe 2 following the surgical electrotome 1, and then starts the infusion pump 53 and opens the infusion valve 54. At this time, the physiological saline in the liquid supply bin 51 can be introduced into the suction pipe 2, and then the physiological saline can flow to the position of the head to soften the eschar and carbonized tissue on the surface of the head. The continuously delivered physiological saline can also be used to cool the head. The softened eschar and carbonized tissue can be beneficial to the subsequent scraping of the eschar and carbonized tissue on the surface of the head by medical staff. After cleaning the eschar and carbonized tissue on the surface of the head, the physiological saline on the head needs to be wiped off to avoid affecting the use of the head.

[0046] Wherein the flue gas from the exhaust pipe 342 will first enter the adsorption chamber 341, flue gas into the physiological saline in the adsorption chamber 341, and the physiological saline as electrolyte solution, can be weak reaction with carbon dioxide gas to generate carbonic acid, thus realizing the adsorption of carbon dioxide gas in the flue gas, ultimately can be conducive to maintain clear field, reduce the risk of operation; At the same time, due to the physiological saline in the smoke pipe 2 in the end of the delivery in the smoke pipe 2 still will remain a part of the physiological saline, at this time open the suction of the smoke pipe 2, this part of the physiological saline remaining in the smoke pipe 2 can be supplemented into the adsorption chamber 341 after the exhaust pipe 342, thus making up the volatilization consumption of physiological saline in the adsorption chamber 341; At this time, it can realize the efficient use of physiological saline remaining in the smoke pipe 2.
