Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a bipolar electrocoagulation forceps and an electrocoagulation device which can be used for intraoperative nerve electrophysiological stimulation and monitoring. Background Art

[0002] Bipolar electrocoagulation forceps are currently a commonly used surgical instrument in electrosurgery, with the advantages of good hemostasis, simple operation, safety and convenience. Compared with the traditional mechanical scalpel, the clinical use of bipolar electrocoagulation forceps can greatly shorten the operation time, reduce the patient's blood loss and blood transfusion, and thus reduce complications. During the operation, when using bipolar electrocoagulation forceps for coagulation, tissue cutting and other operations, in order to avoid damage to the nerves, it is necessary to monitor the presence of nerves.

[0003] However, most of the electrocoagulation forceps currently on the market only have the function of coagulation, and a few have the function of nerve monitoring, but do not have the function of nerve stimulation, and other equipment is required to stimulate the nerves at the fixed site. Specifically, after the tip of the bipolar electrocoagulation forceps is inserted into the surgical site, the tip of the forceps is electrically connected to the monitoring component to form a monitoring circuit. When the monitoring device detects the electrophysiological signal transmitted by the nerve, it can be determined that there is a nerve at that location. When the monitoring device does not detect the electrophysiological signal transmitted by the nerve, it can be determined that there is no nerve at that location. Because the surgical site is in a paralyzed state during the operation, the electrophysiological signal obtained by stimulating the nerve at the fixed site is very weak or even non-existent, resulting in an inability to accurately determine whether there is a nerve, which can easily lead to misoperation and damage to the nerve. Utility Model Content

[0033] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0034] like Figure 1As shown, in one embodiment, an electrocoagulation device is provided, which includes a host device (not shown) and a bipolar electrocoagulation forceps 10 capable of intraoperative nerve electrophysiological stimulation and monitoring, wherein the bipolar electrocoagulation forceps 10 capable of intraoperative nerve electrophysiological stimulation and monitoring are electrically connected to the host device, and a high-frequency current, a monitoring current or a stimulation current corresponding to the gear information is transmitted to the bipolar electrocoagulation forceps 10 capable of intraoperative nerve electrophysiological stimulation and monitoring via the host device. In this way, the host device can transmit high-frequency current to the bipolar electrocoagulation forceps 10 that can stimulate and monitor nerve electrophysiology during surgery to perform coagulation, tissue cutting and other operations on the affected area; the host device can transmit monitoring current to the bipolar electrocoagulation forceps 10 that can stimulate and monitor nerve electrophysiology during surgery to monitor the presence of nerves and avoid damage to the nerves; the host device can transmit stimulation current to the bipolar electrocoagulation forceps 10 that can stimulate and monitor nerve electrophysiology during surgery to stimulate the nerves so that the nerves can transmit electrophysiological signals sufficient to be monitored. Compared with the fixed-site stimulation of the prior art, stronger electrophysiological signals can be obtained, thereby accurately judging whether there are nerves at the surgical site and avoiding damage to the nerves due to misoperation; and, the stimulation current and the monitoring current can flow through the bipolar electrocoagulation forceps 10 at the same time, so that the nerve monitoring operation can be performed immediately after the nerve stimulation at the surgical site. Nerve stimulation and nerve monitoring can be completed at the same time without the use of other equipment, thereby improving surgical efficiency and enhancing the operating experience.

[0035] like Figures 1 to 4 As shown, in one embodiment, a bipolar electrocoagulation forceps 10 capable of intraoperative nerve electrophysiological stimulation and monitoring is provided, including a forceps body 100 and a switch assembly 200 .

[0036] like Figure 1 and Figure 3 As shown, the forceps body 100 includes a first body 110 and a second body 120. During the operation, the tip of the first body 110 and the tip of the second body 120 can be inserted into the surgical site to complete coagulation, tissue cutting, nerve monitoring, nerve stimulation and other operations according to actual surgical needs.

[0037] Specifically, the first body 110 and the second body 120 can both be existing shapes, and the first body 110 and the second body 120 can both be made of conductive materials such as copper. By coating an insulating layer around the first body 110, the tip of the first body 110 is exposed to form a front end that is conductive and the surrounding sides are insulated. By coating an insulating layer around the second body 120, the tip of the second body 120 is exposed to form a front end that is conductive and the surrounding sides are insulated. In this way, after the tip of the first body 110 and the tip of the second 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.

[0038] Optionally, the first body 110 is provided with a first tip portion used as a first electrode, and the second body 120 is provided with a second tip portion used as a second electrode. In the electrocoagulation function, one of the first tip portion and the second tip portion is used as an output electrode and the other as a return electrode; in the nerve electrical stimulation and monitoring function, one of the first tip portion and the second tip portion is used as a stimulation electrode and the other as a receiving electrode.

[0039] Among them, the switch component 200 has a first gear, a second gear and a third gear. The switch component 200 is used to send the corresponding gear information to the host device when it is in the first gear, the second gear or the third gear. That is, when the switch component 200 is in different gears (the first gear, the second gear and the third gear), the host device can be selectively electrically connected to the first body 110 and the second body 120, so as to complete different surgical operations according to actual usage needs.

[0040] 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 switch assembly 200 .

[0041] Specifically, when the switch assembly 200 is in the first position, both the first body 110 and the second 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 switch assembly 200 is switched to the first position, so that the high-frequency current flows through the first body 110 and the second body 120 at the same time to form a loop, thereby enabling coagulation or tissue cutting operations to be performed on the surgical site.

[0042] Specifically, when the switch assembly 200 is in the second position, one of the first body 110 and the second body 120 can be used for the monitoring current to flow through. In this way, when it is necessary to perform nerve monitoring on the surgical site, the switch assembly 200 is switched to the second position so that the monitoring current flows through one of the first body 110 and the second 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.

[0043] Specifically, when the switch assembly 200 is in the third position, the other of the first body 110 and the second body 120 can be used to allow the stimulation current to flow through. In this way, when it is necessary to perform nerve stimulation on the surgical site, the switch assembly 200 is switched to the third position, so that the stimulation current flows through the other of the first body 110 and the second body 120 to form a loop, thereby enabling nerve stimulation to be performed on the surgical site to stimulate the nerves so that the nerves can transmit electrophysiological signals sufficient to be monitored. Compared with the fixed-site stimulation of the prior art, stronger electrophysiological signals can be obtained, thereby accurately determining whether there are nerves at the surgical site to avoid damage to the nerves due to misoperation.

[0044] Furthermore, the switch assembly 200 can be in the second position and the third position at the same time, so that the stimulation current and the monitoring current can flow through their respective bodies (the first body 110 and / or the second body 120) at the same time, thereby enabling nerve stimulation of the surgical site and then immediate nerve monitoring. Neural stimulation and neural monitoring can be completed at the same time without the use of other equipment, thereby improving surgical efficiency and enhancing the operating experience.

[0045] Furthermore, the bipolar electrocoagulation forceps 10 also includes a neutral electrode (not shown), which can be selectively electrically connected or disconnected with the switch assembly 200 according to actual use needs.

[0046] Specifically, when the switch assembly 200 is in the first gear, the first body 110 and the second body 120 are both disconnected from the neutral electrode. In this way, when it is necessary to perform coagulation or tissue cutting operations on the surgical site, the switch assembly 200 is switched to the first gear. At this time, the high-frequency current flows through the first body 110 and the second body 120 at the same time to form a loop and does not flow through the neutral electrode, so that the tip of the first body 110 and the tip of the second body 120 can be used to perform coagulation or tissue cutting operations on the surgical site.

[0047] In one embodiment, high-frequency current flows from one of the first body 110 and the second body 120 into the affected area, and then flows out from the other of the first body 110 and the second body 120 to form a loop, thereby being able to perform coagulation and tissue cutting operations on the affected area.

[0048] Specifically, when the switch assembly 200 is in the second gear, one of the first body 110 and the second body 120 for the monitoring current to flow through forms an electrical circuit with the neutral electrode. In this way, when it is necessary to perform nerve monitoring on the surgical site, the switch assembly 200 is switched to the second gear, so that the monitoring current flows through one of the first body 110 and the second body 120 and the neutral electrode to form a circuit, so that the nerve monitoring operation can be performed on the surgical site to monitor the presence or absence of nerves and avoid nerve damage.

[0049] In one embodiment, the neutral electrode can be brought into contact with the human body, and the monitoring current flows from one of the first body 110 and the second body 120 into the affected area, and then flows out from the neutral electrode to form a loop, so that nerve monitoring operations can be performed on the surgical site to monitor the presence or absence of nerves and avoid damage to the nerves.

[0050] Specifically, when the switch assembly 200 is in the third position, one of the first body 110 and the second body 120 for the stimulation current to flow through forms an electrical circuit with the neutral electrode. In this way, when it is necessary to perform nerve stimulation on the surgical site, the switch assembly 200 is switched to the third position, so that the stimulation current flows through the other of the first body 110 and the second body 120 and the neutral electrode to form a circuit, so that the surgical site can be stimulated to stimulate the nerve so that the nerve can transmit an electrophysiological signal sufficient to be monitored. Compared with the fixed site stimulation of the prior art, a stronger electrophysiological signal can be obtained, so as to accurately determine whether there is a nerve at the surgical site, and avoid damage to the nerve due to misoperation.

[0051] In one embodiment, the neutral electrode can be brought into contact with the human body, and the stimulation current flows from the other one of the first body 110 and the second body 120 into the affected area, and then flows out from the neutral electrode to form a loop, so that nerve stimulation can be performed 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 at the surgical site to avoid damage to the nerves due to misoperation.

[0052] Optionally, the neutral electrode may be in a plate-shaped, strip-shaped, or sheet-shaped structure.

[0053] like Figure 3 and Figure 4 As shown, more specifically, the switch assembly 200 includes a first switch part 210 corresponding to the first gear, a second switch part 220 corresponding to the second gear, and a third switch part 230 corresponding to the third gear, that is, when the first switch part 210 is turned on, it is in the first gear, when the second switch part 220 is turned on, it is in the second gear, and when the third switch part 230 is turned on, it is in the third gear. In addition, the first switch part 210, the second switch part 220, and the third switch part 230 are mutually disconnected. In this way, the first switch part 210, the second switch part 220, and the third switch part 230 are independent of each other, and will not interfere or affect each other. The corresponding switch parts (the first switch part 210, the second switch part 220, and the third switch part 230) can be flexibly selected for conduction according to actual use needs.

[0054] like Figures 1 to 5As shown, in addition, the bipolar electrocoagulation forceps 10 further includes a plug-in element 300. One end of the plug-in element 300 is electrically connected to the switch assembly 200, and the other end of the plug-in element 300 is used to be electrically connected to the host device. In this way, the high-frequency current, monitoring current and stimulation current of the host device are selectively transmitted through the plug-in element 300 to meet the actual use needs.

[0055] The plug-in element 300 may be in the form of a plug or a pin, as long as it can achieve the transmission of the corresponding current.

[0056] like Figure 2 and Figure 4 As shown, in one embodiment, the plug element 300 has a first plug 310, a second plug 320 and a third plug 330 that are mutually disconnected, that is, the first plug 310, the second plug 320 and the third plug 330 transmit current independently of each other. In addition, the first plug 310 is electrically connected to the first switch part 210, the second plug 320 is electrically connected to the second switch part 220, and the third plug 330 is electrically connected to the third switch part 230. In this way, when the first switch part 210 is turned on, the first plug 310 transmits the high-frequency current of the host device to the first body 110 and the second body 120; when the second switch part 220 is turned on, the second plug 320 transmits the monitoring current of the host device to one of the first body 110 and the second body 120; when the third switch part 230 is turned on, the third plug 330 transmits the stimulation current of the host device to the other of the first body 110 and the second body 120.

[0057] In one embodiment, the first plug 310, the second plug 320 and the third plug 330 are integrated into one body. In this way, the first plug 310, the second plug 320 and the third plug 330 can be integrated into one socket, and only one plug is required to achieve docking with the host device, which is convenient for use, and the wires of the three plugs can be bundled to avoid clutter.

[0058] In another embodiment, the first plug 310, the second plug 320 and the third plug 330 are separately provided, so that the first plug 310, the second plug 320 and the third plug 330 can be flexibly selected to be connected with the host device according to actual use needs to avoid interference or influence.

[0059] like Figures 1 to 5As shown, optionally, the bipolar electrocoagulation forceps 10 further includes a handle 400, and one end of the first body 110 and the second body 120 in the same direction is arranged on the handle 400, for example, the handle 400 is arranged at one end away from the tip of the first body 110 and away from the tip of the second body 120. In this way, it is convenient to hold the handle 400 and insert the tip of the first body 110 and the tip of the second body 120 into the surgical site for corresponding operations. Among them, the handle 400 can be a cylindrical structure, and the first body 110 and the second body 120 can be connected to the handle 400 by plugging or snapping.

[0060] like Figures 1 to 4 As shown, in one embodiment, the switch assembly 200 is disposed on the handle 400 by means of a snap connection or the like, so as to facilitate the operation of the switch assembly 200 and flexibly select the gear position.

[0061] In another embodiment, the host device includes a switch assembly 200, that is, the switch assembly 200 is disposed on the host device. In this way, the shift operation can also be performed on the host device.

[0062] The switch assembly 200 includes a toggle switch or a push button switch, so that the gear position can be selected by toggling or pressing.

[0063] like Figure 1 and Figure 2 As shown, in one embodiment, the first switch unit 210, the second switch unit 220 and the third switch unit 230 can be turned on respectively in the form of toggling. For example, the first switch unit 210 is turned on when it is turned to the leftmost side, the second switch unit 220 is turned on when it is turned to the middle, and the third switch unit 230 is turned on when it is turned to the rightmost side.

[0064] like Figure 3 and Figure 4 As shown, in one embodiment, the first switch unit 210, the second switch unit 220 and the third switch unit 230 can be turned on respectively by pressing. For example, the first switch unit 210 is turned on when the left side is pressed, the second switch unit 220 is turned on when the middle side is pressed, and the third switch unit 230 is turned on when the right side is pressed.

[0065] In addition, the host device includes an electrocoagulation component (not shown) for delivering high-frequency current, a monitoring component (not shown) for delivering monitoring current, and a stimulation component (not shown) for delivering stimulation current. In this way, when it is necessary to perform coagulation or tissue cutting operations on the surgical site, the switch component 200 is switched to the first gear. At this time, the electrocoagulation component transmits the high-frequency current to the first body 110 and the second body 120 through the first plug 310 to form a loop, so that the surgical site can be coagulated and tissue cut using the tip of the first body 110 and the tip of the second body 120. When it is necessary to perform nerve monitoring operations on the surgical site, the switch component 200 is switched to the second gear. At this time, the monitoring component transmits the monitoring current to one of the first body 110 and the second body 120 and the neutral electrode through the second plug 320 to form a loop, so that the surgical site can be subjected to nerve monitoring operations to monitor the presence or absence of nerves and avoid nerve damage. When it is necessary to perform nerve stimulation on the surgical site, the switch assembly 200 is switched to the third gear. At this time, the stimulation assembly transmits the stimulation current through the third plug 330 to the other of the first body 110 and the second body 120 and the neutral electrode to form a loop, thereby enabling nerve stimulation on the surgical site to stimulate the nerves so that the nerves can transmit electrophysiological signals sufficient to be monitored by the monitoring assembly, and stronger electrophysiological signals can be obtained, thereby accurately determining whether there are nerves at the surgical site to avoid damage to the nerves due to misoperation.

[0066] It should be noted that the electrocoagulation component can be an existing device that can generate high-frequency current to perform coagulation and tissue cutting operations on the surgical site; the monitoring component can be an existing device that can generate a monitoring current to monitor the presence or absence of nerves; and the stimulation component can be an existing device that can generate a stimulation current to stimulate the nerves so that the nerves can transmit electrophysiological signals sufficient to be monitored by the monitoring component.

[0067] In one embodiment, the electrocoagulation component, the monitoring component and the stimulation component are integrated into one body, so that the host device is modularly arranged, the structure is more compact, takes up less space, and is easy to use.

[0068] In another embodiment, the electrocoagulation component, the monitoring component and the stimulation component are separately provided, so that the electrocoagulation component, the monitoring component and the stimulation component can be flexibly selected to work according to actual use needs to avoid interference or influence.

[0073] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0074] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0075] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it can be directly on the other element or there can be a central element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a central element at the same time. Further, when an element is considered to be "fixed transmission connected" to another element, the two can be fixed in a detachable connection manner or in a non-detachable connection, as long as power transmission can be achieved, such as socketing, snap-on, one-piece molding fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0076] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

[0077] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
