Description

Technical Field

[0001] The present application relates to the field of medical devices, and more particularly, to a surgical instrument and a surgical system including the surgical instrument. Background Art

[0002] Each tissue or organ in the body contains a large number of blood vessels or nerves. During the surgical process, when dissecting tissues, it is necessary to timely stop bleeding for damaged blood vessels according to the situation to reduce bleeding and avoid affecting the surgical field of view; in addition, for some areas with important nerve distributions, during the operation, it is necessary to monitor the bioelectrical signals of the area to be dissected to monitor whether there are nerves passing through the dissected area. For example, cardiac surgery, neurosurgery, tumor resection surgery, otolaryngology surgery, ophthalmology surgery, etc.

[0003] Taking the resection of brain tumors in neurosurgical craniotomy as an example, these tumors are attached near the cerebral cortex or important cranial nerve pathways (such as meningiomas, acoustic neuromas, etc.). During the surgical process, tissue dissection is required, and the electrophysiological signals are monitored at any time to determine whether there are nerves. For the bleeding sites, it is necessary to promptly electrocoagulate to seal the blood vessels and stop bleeding. Currently, during the surgical process, the surgeon needs to constantly replace surgical instruments (dissectors or forceps, bipolar electrocoagulators, bipolar electrophysiological monitoring probes) as needed to perform dissection, electrocoagulation, and physiological monitoring, which seriously affects the surgical time and causes fatigue, psychological pressure, and operation accuracy of the surgeon. In addition, most of the currently used bipolar electrocoagulators and bipolar electrophysiological monitoring probes are disposable, which greatly increases the surgical cost.

[0004] Therefore, how to provide a solution that can at least to some extent solve the above problems has become a technical problem to be solved in this field. Summary of the Invention

The bioelectricity monitoring controller is electrically connected to and communicates with the bioelectricity monitoring device, and the electrocoagulation controller is electrically connected to and communicates with the electrocoagulation device.

[0013] Preferably, the surgical system further includes a conversion device to enable the surgical instrument to be selectively converted between a tissue dissection, electrocoagulation mode and a bioelectricity monitoring mode, wherein: in the tissue dissection or the bioelectricity monitoring mode, the bioelectricity monitoring controller is electrically connected to and communicates with the bioelectricity monitoring device, while the electrocoagulation controller is disconnected from the electrocoagulation device; in the tissue dissection or the electrocoagulation mode, the electrocoagulation controller is electrically connected to and communicates with the electrocoagulation device, while the bioelectricity monitoring controller is disconnected from the bioelectricity monitoring device.

[0014] Preferably, the conversion device is provided on the instrument body of the surgical instrument; or the conversion device is provided on the electric connection line between the bioelectricity monitoring controller and the bioelectricity monitoring device and between the electrocoagulation controller and the electrocoagulation device. In a preferred case, the conversion device is a foot switch; or the conversion device is a software switch in the bioelectricity monitoring controller and / or the electrocoagulation controller.

[0015] Preferably, both the bioelectricity monitoring controller and the electrocoagulation controller are independent of the instrument body of the surgical instrument.

[0016] The surgical instrument proposed in this application has the functions of electrocoagulation and / or bioelectric signal monitoring and tissue dissection. During use, operations such as electrocoagulation, electrophysiological monitoring, or tissue dissection can be selected according to needs. The surgeon can flexibly choose according to needs, which can reduce the time waste caused by frequently replacing surgical instruments during the operation and greatly improve the surgical efficiency.

[0017] Other features and advantages of this application will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The drawings constituting a part of this application are used to provide a further understanding of this application. The schematic embodiments and descriptions thereof of this application are used to explain this application. In the drawings:

[0019] Figure 1 is a schematic diagram of the surgical instrument according to this application.

[0020] Figure 2 is a schematic diagram of the surgical system according to this application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions of this application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] During the operation, especially in operations involving delicate procedures, rich in blood vessels and important nerves, it is necessary to timely stop bleeding of the tissue at the operation site and at the same time monitor whether there are nerve fibers at the dissection site to avoid damaging the nerve fibers during the operation and affecting nerve function. Currently, different surgical instruments need to be frequently replaced during the operation to achieve these functions, which increases the operational complexity and inconvenience. In addition, most of the bioelectricity monitoring devices and electrocoagulation devices are disposable devices, which not only increases the generation of medical waste but also burdens the environment.

[0023] Therefore, according to the first aspect of this application, as Figure 1 shown, a surgical instrument is proposed. The surgical instrument includes an instrument body, which is designed in the form of forceps for tissue dissection and includes a first forcep 11 and a second forcep 12. The surgical instrument is integrally designed with a bioelectricity monitoring device 13 and / or an electrocoagulation device 14, wherein: the bioelectricity monitoring device 13 is used to monitor the bioelectric signals of the tissue to be surgically treated by using the first forcep 11 and the second forcep 12; the electrocoagulation device 14 is used to perform electrocoagulation treatment on the tissue to be surgically treated by using the first forcep 11 and the second forcep 12.

[0024] The forceps form of the above-mentioned instrument body can be an appropriate form. For example, it can be straight forceps, curved forceps, bayonet forceps, etc. The specific form is selected according to the surgical position and surgical type. In this application, bayonet forceps are taken as an example; the front ends of the first forceps 11 and the second forceps 12 are used to operate on tissue dissection, electrocoagulation or bioelectrical signal monitoring; the rear ends have connection areas; the above-mentioned connection areas can be connected by at least one of welding, riveting, bolt connection or integral molding. The rear ends of the first forceps 11 and the second forceps 12 are connected, and the first forceps 11 and the second forceps 12 are independently arranged in areas other than the rear ends, and a certain distance is maintained between the two to facilitate the operator to switch the surgical instrument between the clamping state and the released state.

[0025] The above-mentioned bioelectrical monitoring device 13 and / or electrocoagulation device 14 are arranged on the instrument body to facilitate the operator to switch the functions of the surgical instrument at any time according to needs during the operation, avoid wasting the operation time caused by continuously replacing the instrument during the operation, and reduce the fatigue degree and psychological pressure of the operator. In addition, integrating the bioelectrical monitoring device 13 and / or electrocoagulation device 14 on the surgical instrument can also avoid using disposable bioelectrical monitoring devices or electrocoagulation devices, effectively reducing the operation cost and the usage amount of disposable medical supplies, which conforms to the current medical concept of environmental protection and sustainable development. Secondly, the operator does not need to frequently replace the surgical instrument, which simplifies the operation process, improves the operation efficiency, indirectly shortens the single operation time, makes the patient have a lower exposure risk under anesthesia, and further ensures the safety, smoothness and comfort of the operation.

[0026] When performing the dissection function, the above-mentioned surgical instrument is used to separate the tissue to be treated from other tissues. The tissue to be treated is different tissues in different parts, such as mucosa, tumor tissue, muscle tissue, adipose tissue, fibrous tissue, connective tissue, blood vessels, etc. When performing the electrocoagulation function, the above-mentioned surgical instrument is used to stop bleeding of the tissue to be treated, and the tissue to be treated is blood vessels. Or when performing the dissection function, if it is not certain whether there is a nerve at the dissection site, bioelectrical monitoring is required. At this time, the above-mentioned surgical instrument is used to monitor whether there is a nerve in the tissue to be treated. The tissue to be treated is tissue with or without nerves. If there is a nerve passing through the tissue, this area is bypassed for dissection. If there is no nerve, dissection can be performed.

[0027] According to a preferred embodiment of the present application, for the convenience of using surgical instruments, preferably, the first forceps 11 and the second forceps 12 may include an operating portion and a conductor portion. Among them, the operating portion may include an insulating material and a conductive core disposed inside the insulating material, and the conductor portion may include a conductive material to integrally provide a bioelectricity monitoring device 13 and an electrocoagulation device 14. The above-mentioned operating portion is the part held by the surgeon, which is convenient for the surgeon to operate, realize the clamping state or the loosening state of the first forceps 11 and the second forceps 12, so as to realize the function of tissue dissection; the lengths and thicknesses of the above-mentioned operating portion and the conductor portion can be selected according to actual needs. For example, in tumor resection surgery, the diameter of the conductor portion can be larger; in vascular anastomosis surgery, the diameter of the conductor portion can be smaller. The distance between the above-mentioned conductor portions also needs to be selected according to the actual surgical situation. The above-mentioned operating portion is provided with a conductive core inside for realizing current transmission with the conductor portion to realize the functions of bioelectricity monitoring and / or electrocoagulation. The outside of the above-mentioned operating portion is provided with an insulating material, which can effectively prevent the current from spreading to non-target areas during the operation, reduce the thermal damage to the surrounding tissues, and also prevent the surgeon from being electrocuted or electroburned by the current. The above-mentioned conductor portion is disposed at the first end of the above-mentioned operating portion for performing the functions of bioelectricity monitoring and / or electrocoagulation or tissue dissection. Integrating electrocoagulation and / or bioelectricity monitoring in the first forceps 11 and the second forceps 12 eliminates the need for frequent instrument replacement, simplifies the operation process, and improves the surgical efficiency.

[0028] To increase the usage stability and flexibility of surgical instruments, preferably, the operating part and the conductor part can be of an integrated structure or a detachable connection structure. With an integrated structure, there are no connection gaps or interfaces on the instrument body, avoiding structural wear that may be caused by frequent disassembly and assembly, and eliminating signal transmission deviation or electrocoagulation instability problems caused by loose components, thus enhancing the equipment reliability. Secondly, the integrated design makes the appearance of the instrument more smooth and concise. During the surgical process, the cleaning and disinfection process is more convenient and efficient, reducing the potential corners for bacteria and viruses to hide and breed, and effectively reducing the risk of postoperative infection. With a detachable connection structure, on the one hand, for different surgical requirements, doctors can quickly replace the adapted conductor part. For example, for delicate nerve surgeries that require a highly sensitive conductor part to accurately detect weak electrical signals, while general surgical procedures have relatively lower requirements for the conductor. The detachable design enables the use of one "forceps" for multiple purposes, improving the utilization rate of the instrument and reducing the instrument procurement cost. On the other hand, the detachable connection facilitates daily maintenance and troubleshooting. Once a fault occurs in the conductor part, there is no need to scrap the forceps as a whole. Only the damaged component needs to be replaced, which not only saves the maintenance cost but also enables the instrument to return to the normal use state in a short time, ensuring that the surgical arrangement is not affected by the instrument maintenance cycle. The integrated structure or the detachable connection structure of the operating part and the conductor part can be selected according to actual needs. The above-mentioned detachable connection methods can be threaded fit, snap fit, plug-in fit, magnetic fit, spring lock fit, etc. In this application, it is not limited to the above connection methods, as long as the method that can firmly connect the operating part and the conductor part can be applied to the detachable connection method in this application.

[0029] To ensure the smoothness and safety of the operation of surgical instruments during use, preferably, the surface of the conductor part can be a smooth surface, and an anti-tissue adhesion coating can be provided on the outside. This coating is a conductive coating. In a preferred case, the material of the conductive coating can be one of titanium oxide coating, tungsten carbide coating, platinum coating, or diamond coating. The conductive coating not only provides excellent electrical conductivity to ensure the accuracy of current transmission but also has good corrosion resistance, high-temperature resistance, and biocompatibility, increasing the durability and stability of the instrument. The above conductive coating is preferably a platinum coating. The platinum coating has excellent electrical conductivity, corrosion resistance, and biocompatibility, can be in contact with human tissues for a long time, can effectively improve the stability and safety of surgical instruments, and also shows good durability in high-temperature environments. By setting a smooth surface on the surface of the above conductor part and coating an anti-tissue adhesion conductive coating, tissue adhesion can be effectively reduced, and the smoothness and safety of surgical operations can be improved. At the same time, the smooth surface reduces the cleaning difficulty and improves the hygiene of the instrument, making it suitable for repeated use.

[0030] To ensure the durability and safety of surgical instruments, preferably, the conductive core can be one of stainless steel, titanium alloy, copper alloy, silver alloy, platinum alloy, copper, aluminum, copper alloy, tin-plated copper, and silver-plated copper, preferably titanium alloy. Titanium alloy has excellent biocompatibility, high strength, and low weight, making it suitable for surgical instruments that require high-precision operation. Titanium alloy can effectively resist corrosion in the body and maintain long-term stability; and / or the insulating material can be one of ceramic, polytetrafluoroethylene, polyimide, polyethylene, polyvinyl chloride, silicone, polyurethane, epoxy resin, polypropylene, or polycarbonate, preferably polytetrafluoroethylene, which has excellent high-temperature resistance, chemical stability, and electrical insulation properties, is suitable for long-term operation environments, can effectively avoid current leakage, and ensure the safety of patients and surgeons; and / or the conductive material can be at least one of stainless steel, copper, nickel alloy, titanium, platinum, titanium alloy, copper alloy, silver alloy, or platinum alloy, preferably platinum alloy or titanium alloy, and more preferably platinum alloy. Platinum alloy as a conductive material has very high electrical conductivity and corrosion resistance, can ensure the stable transmission of current, provide precise control during surgery, and avoid tissue damage caused by unstable current. The above materials can achieve efficient current transmission, excellent corrosion resistance, biocompatibility, and mechanical strength of surgical instruments. The conductive material ensures the stable flow of current, and the insulating material effectively isolates the current to prevent leakage and improve safety. At the same time, the high-temperature resistance, chemical resistance, and good cleanliness of these materials improve the durability and convenience of the equipment, meet the surgical requirements of high-frequency use, and ensure the accuracy and stability of surgical operations.

[0031] To achieve bioelectric monitoring and / or electrocoagulation, preferably, a bioelectric monitoring device 13 may be provided on one of the first forceps 11 and the second forceps 12, and an electrocoagulation device 14 may be provided on the other, so as to achieve monopolar electrocoagulation and monopolar electrophysiological monitoring; in the above monopolar electrophysiological monitoring, one of the first forceps 11 and the second forceps 12 serves as a stimulating electrode for contacting tissue and applying an electrical signal in the stimulation mode, or recording a bioelectric signal in the recording mode; the other serves as a reference electrode, forming a potential difference with the stimulating electrode to ensure that there is a known reference point for the bioelectric signal, so as to accurately test and analyze the bioelectric signal; the above reference electrode may also be the patient's skin or other stable potential points; in the above monopolar electrocoagulation, one of the first forceps 11 and the second forceps 12 serves as an electrocoagulation tip, contacting the tissue and transmitting high-frequency current to coagulate blood vessels. When performing monopolar electrocoagulation operation, a large-area electrode patch is also provided on the patient's body and connected to the grounding tip, and one end of the grounding tip is connected to the electrocoagulation controller to ensure that the current can return to the electrocoagulation controller. The above grounding tip is not one of the first forceps 11 and the second forceps 12. The combined application of monopolar electrocoagulation and monopolar bioelectrophysiological monitoring can achieve real-time tissue electrophysiological monitoring and precise electrocoagulation operation during the operation, and is suitable for complex operations that require high precision, high safety and real-time feedback. It helps the surgeon accurately control the operation process, reduce the risk of complications, protect important nerves and tissues, and improve the operation efficiency and safety. Or the bioelectric monitoring device 13 and the electrocoagulation device 14 may be respectively provided on the first forceps 11 and the second forceps 12 to achieve bipolar electrocoagulation and bipolar bioelectric monitoring. In this application, taking bipolar electrocoagulation and bipolar bioelectric monitoring as an example, the above instrument body is in the form of forceps, which can achieve tissue dissection on the one hand, and form a bipolar between the first forceps 11 and the second forceps 12 on the other hand, so as to achieve bipolar electrocoagulation and bipolar electrophysiological monitoring. In bipolar electrophysiological monitoring and bipolar electrocoagulation, one of the first forceps 11 and the second forceps 12 serves as the positive electrode. The other serves as the negative electrode, and the current passes through the positive electrode, the tissue between the two electrodes, and then flows to the negative electrode.

[0032] The signal resolution of bipolar electrophysiological monitoring is higher, the signal is more accurate, and it is suitable for identifying weak or local nerve activities; bipolar electrophysiological monitoring is limited to local current, and clean signals can also be obtained in complex operations, which can accurately locate the active parts of nerve fibers, avoid misjudging the activities of other regions, and can also reduce signal mixing and avoid the risks of false positives and false negatives; the stimulating current is limited between the electrodes, avoiding excessive stimulation of the surrounding tissue and reducing the risk of intraoperative nerve injury. It is suitable for surgeries that require high-precision nerve function protection.

[0033] Bipolar electrocoagulation is adopted. The current only flows between two electrodes, and the energy is concentrated between the clamped tissues, which can reduce the thermal damage to the surrounding tissues. Secondly, the current path of bipolar electrocoagulation is short and will not interfere with other devices. By using forceps to clamp blood vessels, precise hemostasis can be achieved with good results. It is applicable to surgeries that require fine control and are close to important tissues, such as brain tumor resection and vascular malformation surgeries in neurosurgery, and can also be applied to ophthalmic surgeries, minimally invasive surgeries, and other surgeries that require fine operations.

[0034] According to the second aspect of the present application, as Figure 2 shown, a surgical system is proposed. The surgical system may include a surgical instrument, a bioelectricity monitoring controller 15, and an electrocoagulation controller 16. The surgical instrument is the above-mentioned surgical instrument. The bioelectricity monitoring controller 15 is electrically connected and communicates with the bioelectricity monitoring device 13, and the electrocoagulation controller 16 is electrically connected and communicates with the electrocoagulation device 14. Both the bioelectricity monitoring controller 15 and the electrocoagulation controller 16 are independent of the instrument body of the surgical instrument and are electrically connected to the second end of the above-mentioned instrument body. The above electrical connection can be in an appropriate manner, such as a fixed electrical connection or a detachable electrical connection. The detachable electrical connection method can be one of screw fitting, spring clip connection, and snap connection. The detachable electrical connection method facilitates the disinfection and sterilization treatment of the instrument body.

[0035] In order to facilitate the switching of different functions of the surgical system during the operation, preferably, the surgical system may further include a conversion device to enable the surgical instrument to be selectively switched between tissue dissection, electrocoagulation mode, and bioelectricity monitoring mode, where: in the tissue dissection or bioelectricity monitoring mode, the bioelectricity monitoring controller 15 and the bioelectricity monitoring device 13 may be electrically connected and communicate with each other, while the electrocoagulation controller 16 and the electrocoagulation device 14 are disconnected; in the tissue dissection or electrocoagulation mode, the electrocoagulation controller 16 and the electrocoagulation device 14 are electrically connected and communicate with each other, while the bioelectricity monitoring controller 15 and the bioelectricity monitoring device 13 are disconnected. By integrating the conversion device, the surgical system enables flexible switching between tissue dissection, electrocoagulation mode, and bioelectricity monitoring mode to meet the requirements of different stages during the operation. It improves the flexibility and safety of the operation, avoids function interference, simplifies the operation process, while enhancing the operation accuracy and efficiency, reduces the types of equipment and management complexity, and ensures that the tissue dissection, electrocoagulation, and bioelectricity monitoring functions during the operation are independent of each other and precisely controlled, which helps to improve patient safety.

[0036] For the convenience of converting different functions of the surgical instrument, preferably, the conversion device can be arranged on the instrument body of the surgical instrument; or the conversion device can be arranged on the electrical connection lines between the bioelectric monitoring controller 15 and the bioelectric monitoring device 13 and between the electrocoagulation controller 16 and the electrocoagulation device 14. In a preferred case, the conversion device is a foot switch; or the conversion device is a software switch in the bioelectric monitoring controller 15 and / or the electrocoagulation controller 16. By setting the conversion device as a foot switch or a software switch, the surgical system can conveniently switch between the electrocoagulation mode and the bioelectric monitoring mode, improving the flexibility and operation efficiency of the system. The foot switch is convenient for the surgeon not to operate with hands during the operation, reducing interference, while the software switch simplifies the operation interface, making the system more intelligent. This design improves the surgical precision, reduces misoperation, enhances safety, optimizes the use of space and cost, enhances the adaptability and versatility of the device, and ensures precise control and patient safety during the operation.

[0037] The preferred embodiments of the present application have been described in detail above. However, the present application is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present application, various simple modifications can be made to the technical solutions of the present application, and these simple modifications all belong to the protection scope of the present application.

[0038] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present application will not separately describe various possible combination methods.

[0039] In addition, any combination can be made between various different embodiments of the present application as long as it does not violate the idea of the present application, and it should also be regarded as the content disclosed in the present invention.
