[0044] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The electrocoagulation forceps currently on the market only have the coagulation function, and a few have the function of nerve monitoring, but do not have the function of nerve stimulation. In actual surgical procedures, the surgical site of the patient is usually in a paralyzed state. At this time, the electrophysiological signal transmitted by the nerve is very weak or even absent. The existing electrocoagulation forceps cannot effectively monitor the electrophysiological signal, and cannot effectively detect whether the nerve is damaged, and cannot play a role in assisting surgery. In order to overcome the deficiencies in the prior art, the utility model provides an electrocoagulation forceps with intraoperative neuroelectrophysiological monitoring function and a function gating circuit. On the basis of the existing electrocoagulation forceps, a gating control module and an electrophysiological stimulation module are added. The electrophysiological stimulation module can release a nerve stimulation signal to electrically stimulate the paralyzed nerve tissue, so that the nerve can transmit an electrophysiological signal sufficient to be monitored, and then the electrophysiological monitoring module monitors the electrophysiological signal of the nerve tissue to detect whether the nerve is damaged, thereby playing a role in assisting doctors in surgery.

[0046] Furthermore, in actual surgical scenarios, it is impossible to perform coagulation, tissue cutting and electrical stimulation on the surgical site of the patient at the same time, so the electrocoagulation generation module and the electrophysiological stimulation module cannot work at the same time. Generally, it is necessary to perform electrophysiological monitoring while electrically stimulating the paralyzed surgical site, so the electrophysiological stimulation module and the electrophysiological monitoring module can work at the same time. In order to achieve the above-mentioned working purpose, and at the same time to avoid the user's misoperation when selecting the working mode of the electrocoagulation forceps, causing surgical accidents, the utility model further provides a corresponding gating control module, which includes multiple gating enable terminals, multiple logic gate circuits and multiple working enable terminals. Through the gating control module provided by the utility model, the electrophysiological stimulation module or the electrophysiological monitoring module will not be selected at the same time as the electrocoagulation generation module, that is, they will not work at the same time, avoiding surgical accidents caused by doctor's misoperation, and the electrophysiological stimulation module and the electrophysiological monitoring module can work at the same time, so that electrophysiological monitoring of paralyzed nerve tissue can be realized.

[0050] When the surgical site of the patient is usually in a paralyzed state, the doctor selects the electrophysiological stimulation module 52, which can electrically stimulate the nerve tissue according to the work enable signal, so that the nerve can generate electrophysiological signals sufficient to be monitored; then the electrophysiological monitoring module 53 monitors the electrophysiological signals of the nerve tissue to detect whether the nerve is damaged.

[0051] Since in actual surgical scenarios, it is impossible to perform coagulation, tissue cutting and electrical stimulation operations on the patient's surgical site at the same time, the electrocoagulation module 54 and the electrophysiological stimulation module 52 cannot work at the same time. Generally, it is necessary to perform electrophysiological monitoring operations while electrically stimulating the paralyzed surgical site. Therefore, the electrophysiological stimulation module 52 and the electrophysiological monitoring module 53 can work at the same time.

[0052] In order to achieve the above-mentioned working objectives and at the same time to avoid the user's misoperation when selecting the working mode of the electrocoagulation forceps, thereby causing surgical accidents, the utility model further provides a corresponding selection control module.

[0056] The output end of the third AND gate circuit U3 is connected to the input end of the third work enable end DN_EN_OUT, and the output end of the third work enable end DN_EN_OUT is used to output a work enable signal, specifically to output a high-frequency current signal to perform coagulation and / or tissue cutting on the lesion tissue.

[0058] Through the selection control module 51 provided by the utility model, the electrophysiological stimulation module 52 or the electrophysiological monitoring module 53 will not be selected at the same time as the electrocoagulation generation module 51, that is, they will not work at the same time, thereby avoiding surgical accidents caused by doctor's misoperation, and the electrophysiological stimulation module 52 and the electrophysiological monitoring module 53 can work at the same time to realize electrophysiological monitoring of paralyzed nerve tissue.

[0062] Figure 4 One of the structural schematic diagrams of an electrocoagulation forceps device with intraoperative neuroelectrophysiological monitoring function provided by the embodiment of the utility model, please refer to Figure 4 As shown, the electrocoagulation forceps device with intraoperative neuroelectrophysiological monitoring function includes an electrocoagulation forceps 10 and a host ( Figure 4 (not shown in the figure), the main control module 50, the gating control module 51, the electrophysiological stimulation module 52, the electrophysiological monitoring module 53 and the electrocoagulation generation module 54 are all arranged in the host, and the output end of the electrophysiological stimulation module 52, the output end of the electrophysiological monitoring module 53 and the output end of the electrocoagulation generation module 54 are all electrically connected to the electrocoagulation forceps 10. In other words, the electrocoagulation forceps 10 are plugged into the host through a cable, and the host transmits signals and energy to the electrocoagulation forceps 10 through the cable to control the operation of the electrocoagulation forceps 10.

[0063] Please refer to Figure 4 As shown, the electrocoagulation forceps 10 includes a first forceps body 110 and a second forceps body 120. Both the first forceps body 110 and the second forceps body 120 can be made of conductive materials such as copper. An insulating layer is coated on the periphery of the first forceps body 110 so that the tip of the first forceps body 110 is exposed to form a conductive front end and insulating on the periphery. An insulating layer is coated on the periphery of the second forceps body 120 so that the tip of the second forceps body 120 is exposed to form a conductive front end and insulating on the periphery. In this way, after the tips of the first forceps body 110 and the second forceps body 120 are inserted into the surgical site, operations such as coagulation, tissue cutting, nerve monitoring and nerve stimulation can be completed according to actual surgical needs.

[0064] Specifically, during operation, the electrophysiological stimulation module 52 is used to generate a stimulation current, which flows through the first forceps body 110 and the second forceps body 120 to electrically stimulate the nerve tissue; the electrophysiological monitoring module 53 is used to generate an electrophysiological monitoring signal, which flows through the first forceps body 110 or the second forceps body 120 to perform neural monitoring on the nerve tissue. The electrocoagulation generation module 54 is used to generate a high-frequency current signal, which flows through the first forceps body 110 and the second forceps body 120 to perform coagulation and / or tissue cutting on the lesion tissue.

[0065] In one embodiment, please refer to Figure 4As shown, the multifunctional electrocoagulation forceps device further includes a power supply component 300, one end of the power supply component 300 is electrically connected to the main control module 50, and the other end is used to connect to a power supply to supply power to the electrocoagulation forceps.

[0066] Please refer to Figure 4 As shown, in one embodiment, the electrocoagulation forceps 10 further includes a handle 400 (i.e., a handheld portion), the first forceps body 110 and the second forceps body 120 are arranged at one end of the handle 400, and the power supply assembly 300 is arranged at the other end of the handle 400;

[0067] The multi-function switch 200 in this embodiment is a sliding switch, and the multi-function switch 200 is disposed outside the housing of the handle 400 .

[0068] In one embodiment, the electrocoagulation forceps with intraoperative neuroelectrophysiological monitoring function can be designed as an integrated structure. The electrocoagulation forceps 10 include a handle 400, a first forceps body 110 and a second forceps body 120 are arranged at one end of the handle 400, and a power supply component 300 is arranged at the other end of the handle 400; the main control module 50, the selection control module 51, the electrophysiological stimulation module 52, the electrophysiological monitoring module 53, the electrocoagulation generation module 54 and the switch control module 55 are all arranged inside the shell of the handle 400, and an insulating layer is arranged between each circuit module and the outside of the shell of the handle 400 to prevent leakage of electricity during the operation of the electrocoagulation forceps.

[0069] In one embodiment, the multi-function switch 200 has a first gear, a second gear, and a third gear, that is, when the multi-function switch 200 is in different gears (the first gear, the second gear, and the third gear), it can selectively achieve electrical connection with the first tweezers body 110 and the second tweezers body 120, thereby completing different surgical operations according to actual usage needs.

[0070] It should be noted that the first gear position, the second gear position and the third gear position refer to three different electrical states of the multi-function switch 200 .

[0071] Specifically, when the multi-function switch 200 is in the first position, both the first forceps body 110 and the second forceps body 120 can be used to allow high-frequency current to flow through. In this way, when coagulation or tissue cutting operations are required at the surgical site, the multi-function switch 200 is switched to the first position, so that the high-frequency current flows through the first forceps body 110 and the second forceps body 120 at the same time to form a circuit, thereby enabling coagulation or tissue cutting operations to be performed on the surgical site.

[0072] Specifically, when the multi-function switch 200 is in the second position, one of the first tweezers body 110 and the second tweezers body 120 can be used for monitoring current to flow through. In this way, when it is necessary to perform nerve monitoring on the surgical site, the multi-function switch 200 is switched to the second position so that the monitoring current flows through one of the first tweezers body 110 and the second tweezers body 120 to form a loop, thereby enabling nerve monitoring of the surgical site to monitor the presence or absence of nerves and avoid damage to the nerves.

[0073] Specifically, when the multi-function switch 200 is in the third position, the other one of the first tweezers 110 and the second tweezers 120 can be used for the stimulation current to flow through. In this way, when it is necessary to perform nerve stimulation operation on the surgical site, the multi-function switch 200 is switched to the third position, so that the stimulation current flows through the other one of the first tweezers 110 and the second tweezers 120 to form a loop, thereby enabling nerve stimulation operation on the surgical site to stimulate the nerves so that the nerves can transmit electrophysiological signals sufficient to be monitored, thereby accurately determining whether there are nerves in the surgical site to avoid damage to the nerves due to misoperation.

[0074] In one embodiment, the electrocoagulation forceps 10 further includes a neutral electrode. Figure 5 The schematic diagram of the neutral plate structure provided in the embodiment of the utility model, the output end of the electrophysiological stimulation module 52 and the output end of the electrophysiological monitoring module 53 are also electrically connected to the neutral plate 60. When working, the electrophysiological stimulation module 52 is used to generate a stimulation current, and the stimulation current flows through the first tweezers body 110 and the neutral plate 60 to form a nerve stimulation circuit to electrically stimulate the nerve tissue; the electrophysiological monitoring module 53 is used to obtain an electrophysiological monitoring signal, and the electrophysiological monitoring signal flows through the first tweezers body 110 and the neutral plate 60 to form a nerve monitoring circuit to perform nerve monitoring on the nerve tissue. It should be noted that here only the first tweezers body 110 is used as an example for explanation. In actual design, an electrical circuit can be formed for any one of the first tweezers body 110 and the second tweezers body 120 and the neutral plate 60 to achieve the above-mentioned nerve stimulation and electrophysiological monitoring functions.

[0075] In one embodiment, when the multi-function switch 200 is in the third position, any one of the first forceps body 110 and the second forceps body 120 is electrically connected to the neutral electrode 60. Thus, when it is necessary to perform nerve stimulation on the surgical site, the multi-function switch 200 is switched to the third position, so that the stimulation current flows through any one of the first forceps body 110 and the second forceps body 120 and the neutral electrode 60 to form a loop, thereby performing nerve stimulation on the surgical site, stimulating the nerve so that the nerve can transmit an electrophysiological signal sufficient to be monitored, thereby accurately determining whether there is a nerve at the surgical site to avoid damage to the nerve due to misoperation.

[0076] In one embodiment, the neutral electrode can be brought into contact with the surgical site, and the monitoring current flows from one of the first tweezers 110 and the second tweezers 120 into the affected area, and then flows out from the neutral electrode 60 to form a loop, so that nerve monitoring can be performed on the surgical site to monitor whether there are nerves in the current surgical site and avoid damage to the nerves.

[0077] In one embodiment, the multi-function switch 200 can be set to only two gears. When the multi-function switch 200 is in the first gear, the electrocoagulation forceps 10 first performs nerve stimulation on the paralyzed part and performs electrophysiological monitoring on the paralyzed part; when the multi-function switch 200 is in the second gear, the electrocoagulation forceps 10 can perform coagulation and tissue cutting operations on the affected area.

[0078] In one embodiment, after the electrocoagulation generating module 54 is activated, the bipolar electrocoagulation forceps 10 can be used to coagulate the tissue. During this process, the intraoperative electrophysiological stimulation module 52 and the electrophysiological monitoring module 53 can be selectively started to diagnose and analyze the nerve tissue at the surgical site to determine whether the surrounding nerves are damaged, provide doctors with clinical intraoperative diagnosis, diagnose related symptoms in advance and intervene in treatment to avoid secondary injuries to patients after surgery.

[0079] Figure 6 The second schematic diagram of the structure of a multifunctional electrocoagulation forceps device provided by the embodiment of the utility model, please refer to Figure 6 As shown, the multifunctional switch 200 may be a button switch, specifically including a stimulation function button 210 , a monitoring function button 220 and an electrocoagulation function button 230 .

[0080] In one embodiment, the multi-function switch 200 is a foot-operated control switch; the foot-operated control switch is electrically connected to the switch control module 55 via a signal line. During the operation, the doctor can switch the working mode of the electrocoagulation forceps through the foot-operated control switch, which can free both hands and facilitate the operation.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
