Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a high-frequency energy host and a high-frequency surgical device. Background Technology

[0002] High-frequency surgical equipment typically consists of a high-frequency energy generator and a surgical blade. The blade applies energy from the high-frequency energy generator to the lesion tissue to achieve a range of surgical functions. Operators can change blades to achieve different surgical outcomes depending on the specific surgical needs. The high-frequency energy generator also performs identification and verification when connected to the blade to prevent issues such as incorrect blade specifications or blade detachment.

[0003] Currently, the identification and verification between high-frequency energy generators and cutting tools is typically achieved through inductive identification (such as NFC, encrypted chip identification, etc.). This identification method is a digital technology that relies on data communication. However, when the energy frequency output by the high-frequency energy generator is high, such as reaching megahertz levels or above, inductive identification can be affected by high-frequency radiation, leading to problems such as inability to identify or incorrect identification. If the generator is outputting energy but cannot accurately and effectively verify the correctness of the cutting tool's specifications or its stable connection, and the tool falls out or is disconnected, the energy output from the generator will not follow the ideal loop, potentially leading to surgical risks or harm to the operator or patient.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0041] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a high-frequency surgical device provided by this utility model. As shown, the high-frequency surgical device consists of a high-frequency energy host and a cutting tool. The cutting tool receives energy output from the high-frequency energy host to achieve a series of medical functions. When facing different medical needs, the operator can achieve different medical effects by changing the cutting tool. The host will also identify and confirm the connection with the cutting tool to avoid problems such as incorrect tool specifications or tool detachment.

[0042] Currently, the identification and verification between high-frequency energy generators and cutting tools is typically achieved through inductive identification (such as NFC, encrypted chip identification, etc.). This identification method is a digital technology that relies on data communication. However, when the energy frequency output by the high-frequency energy generator is high, reaching megahertz or higher, inductive identification can be affected by high-frequency radiation, leading to problems such as inability to identify or incorrect identification. If the generator is outputting energy but cannot accurately and effectively verify the correctness of the cutting tool's specifications or its stable connection, and the tool falls out or is disconnected, the energy output from the generator will not follow the ideal loop, potentially leading to surgical risks or harm to the operator or patient.

[0043] Therefore, refer to Figures 1 to 4 This utility model proposes a high-frequency energy host, which includes an interface for connecting a cutting tool and an energy output circuit. The energy output circuit is used to output energy to the connected cutting tool to achieve a series of medical functions. The high-frequency energy host also includes:

[0044] Access detection component 10 is disposed close to the interface and is used to detect the access status of the interface and output a corresponding access detection signal;

[0045] The prompting circuit 20 is electrically connected to the access detection component 10 and is used to receive the access detection signal and output a corresponding prompting signal. The prompting circuit is used to indicate the access status.

[0046] The control circuit 30 is electrically connected to the access detection component 10 and the energy output circuit, respectively, and is used to receive the access detection signal and output a corresponding tool drive signal. The tool drive signal is used to control the working state of the energy output circuit.

[0047] It should be understood that high-frequency energy generators and cutting tools are typically connected via a male-female connector. The female connector on the high-frequency energy generator is used to connect the cutting tool, while the cutting tool has a corresponding male connector. The generator is compatible with various cutting tools and accessories. This detachable connection allows the high-frequency energy generator to achieve different medical effects by changing the cutting tool. For example, when the cutting tool connected to the high-frequency energy generator is a bipolar electrosurgical unit, the user can perform delicate procedures and coagulation. Types of bipolar electrosurgical units include cutting blades, coagulation blades, electrocoagulation forceps, and incision blades. Therefore, the high-frequency energy generator can also select the corresponding energy output mode by confirming the type of cutting tool connected. The method of confirming the cutting tool type can be achieved using inductive identification (such as NFC, encrypted chip identification, etc.).

[0048] In this embodiment, the access detection component 10 can be implemented using a mechanical trigger switch assembly, a Hall effect sensor, a photoelectric sensor, or a capacitive sensor, etc. The access detection component 10 is installed at the interface of the high-frequency energy host for tool access, thereby detecting tool engagement and outputting an access detection signal. Please refer to [link to relevant documentation]. Figure 5 Taking the access detection component 10 as an example, which is a mechanical trigger switch assembly, the triggering element of the mechanical trigger switch assembly is located in the pin hole of the female connector of the high-frequency energy host interface. When the male connector of the tool is connected to the female connector of the high-frequency energy host interface, the pins on the male connector will insert into the corresponding pin holes, thereby contacting the triggering element and causing the mechanical trigger switch assembly to output an access detection signal. Furthermore, this triggering element can be implemented using a physical switch, which is turned on when triggered and turned off when not triggered, thereby realizing the detection of the interface access status.

[0049] In this embodiment, the prompting circuit 20 can be implemented using a voice prompting circuit, a visual prompting circuit, a vibration prompting circuit, etc. Specifically, to achieve rapid confirmation of the access status, the prompting circuit 20 is electrically connected to the access detection component 10. This allows it to receive the access detection signal output by the access detection component 10 and quickly confirm the output of the prompting signal, avoiding the delay caused by controlling the prompting circuit 20 to output the prompting signal via the control circuit 30. Please refer to [link to relevant documentation]. Figure 1 Taking the visual prompting circuit 20 as an example, the visual prompting circuit includes an LED indicator light. When a tool is connected to the interface of the high-frequency energy host, the system receives the connection detection signal output by the connection detection component 10 to confirm that the interface is currently in the connected state and illuminates the LED indicator light. Taking the voice prompting circuit 20 as an example, when a tool is connected to the interface of the high-frequency energy host, the system receives the connection detection signal output by the connection detection component 10 to confirm that the interface is currently in the connected state and outputs a corresponding voice prompt signal indicating that the interface is in the connected state. When no tool is connected to the interface of the high-frequency energy host, the system receives the connection detection signal output by the connection detection component 10 to confirm that the interface is currently in the unconnected state and outputs a corresponding voice prompt signal indicating that the interface is not in the connected state.

[0050] In this embodiment, the control circuit 30 can be implemented using a main controller, such as a DSP (Digital Signal Processor), MCU (Microcontroller Unit), FPGA (Field Programmable Gate Array), or SOC (System-on-Chip). By receiving the access detection signal, it determines whether the interface of the high-frequency energy host is connected to a tool and whether to output an energy control signal, thereby controlling the operating state of the energy output circuit. It should be understood that the control circuit 30 itself also receives user-input energy output commands such as those from buttons or foot pedals. Therefore, the control circuit 30 outputs a tool drive signal to the energy output circuit based on the user-input energy output command and the access detection signal; that is, the tool drive signal is only output when both the user-input energy output command and the interface are currently connected.

[0051] By employing the access detection component 10, the access status of the high-frequency energy host interface can be detected when a cutting tool is connected to the interface, and an access detection signal can be output. The prompting circuit 20 will acquire this access detection signal and output a corresponding prompt signal based on the access detection signal, so as to intuitively inform the user of the access status of the high-frequency energy host interface. The control circuit 30, by receiving the access detection signal output by the access detection component 10, confirms the access status of the host interface and outputs an energy control signal, thereby controlling the operation of the energy control board. This effectively ensures that the high-frequency energy host outputs energy when its interface is connected to the cutting tool, improving the safety of the high-frequency surgical equipment.

[0052] In one embodiment of the present invention, the access detection component 10 includes a slotted optical coupler detection component, which is used to output a first detection signal when a tool is connected to the interface; the slotted optical coupler detection component is also used to output a second detection signal when no tool is connected to the interface.

[0053] In this embodiment, the access detection component 10 is implemented using a slotted optical coupler detection component, and the access status of the interface is determined by the access detection signal output by the slotted optical coupler detection component. The access detection signal includes a first detection signal and a second detection signal. The first detection signal corresponds to the signal output when the tool is connected to the high-frequency energy host, and the second detection signal corresponds to the signal output when the tool is not connected to the high-frequency energy host.

[0054] Furthermore, the interface has at least one pin hole for corresponding to the pin of the tool; the light-collecting slot of the slotted optical coupler detection component is provided corresponding to any of the pin holes;

[0055] When the cutting tool is connected to the interface, the tool's pin is inserted into the pin hole and into the light-collecting slot; the slot-type optical coupler detection component is used to output a first detection signal when the pin is inserted into the light-collecting slot.

[0056] In this embodiment, the interface has multiple pin holes corresponding to the tool pins to facilitate the separate transmission of energy and data between the high-frequency energy host and the tool. Among the tool pins, there is a set of grounding pins, which are slightly longer than the others for grounding protection. The other pins have the same length. The pin holes of the high-frequency energy host interface must be correspondingly configured to accommodate the differences in the number and length of the tool pins. It is understood that when the number of tool pins always corresponds to the number of pin holes of the high-frequency energy host interface, the light-collecting slot of the slot-type optocoupler detection component can be configured to correspond to any pin hole. When a pin is connected to any pin hole, it can be detected by the optocoupler detection component. Furthermore, to ensure a complete connection between the tool and the high-frequency energy host, the light-collecting slot of the slot-type optocoupler detection component can be located at the end of the pin hole furthest from the outer casing, so that the first detection signal is output only when the pin on the tool is fully connected to the pin hole. When no pin is connected to the pin hole, a second detection signal is output.

[0057] Optionally, to prevent the slotted optocoupler detection component from being falsely triggered due to foreign objects in the pin hole, multiple sets of slotted optocoupler components can be set to correspond to multiple pin holes respectively. Only when multiple sets of slotted optocoupler components in multiple pin holes are blocked can the connected detection component 10 output the first detection signal.

[0058] refer to Figures 3 to 4 In one embodiment of this utility model, the slotted optical coupler detection component includes:

[0059] power supply

[0060] A slotted optocoupler circuit 11 is electrically connected to the power supply terminal. When a tool is connected to the interface, it outputs a first optocoupler signal; when no tool is connected to the interface, it outputs a second optocoupler signal.

[0061] The switch circuit 12 is electrically connected to the slotted optocoupler circuit 11, the first end of the switch circuit 12 is electrically connected to the power supply terminal and the control circuit 30, and the second end of the switch circuit 12 is electrically connected to the ground terminal. It is used to receive the first optocoupler signal and output a first detection signal; it is also used to receive the second optocoupler signal and output a second detection signal.

[0062] In this embodiment, the slot-type optocoupler detection component consists of a power supply terminal, a slot-type optocoupler circuit 11, and a switching circuit 12. One end of the slot-type optocoupler circuit 11 is electrically connected to the power supply terminal, and the other end is electrically connected to the switching circuit 12. It detects whether there is any obstruction in the light-collecting slot of the slot-type optocoupler circuit 11, thereby outputting a first optocoupler signal or a second optocoupler signal to change the on / off relationship between the power supply terminal and the switching circuit 12. Specifically, the slot-type optocoupler circuit 11 includes a first resistor R1, a second resistor R2, and a slot-type optocoupler; the switching circuit 12 includes a third resistor R3, a fourth resistor R4, a fifth resistor R5, a first NMOS transistor Q1, and a second NMOS transistor Q2.

[0063] Wherein, the first end of the first resistor R1 is electrically connected to the power supply terminal, and the second end of the first resistor R1 is electrically connected to the anode of the light-emitting diode of the slotted optocoupler; the cathode of the slotted optocoupler is electrically connected to the ground terminal; the first end of the second resistor R2 is electrically connected to the power supply terminal, and the second end of the second resistor R2 is electrically connected to the first end of the phototransistor of the slotted optocoupler; the second end of the phototransistor is electrically connected to the gate of the first NMOS transistor Q1 and the first end of the third resistor R3; the second end of the third resistor R3 is electrically connected to the ground terminal; the drain of the first NMOS transistor Q1 is electrically connected to the second end of the fourth resistor R4, the gate of the second NMOS transistor Q2, and the first end of the fifth resistor R5; the source of the first NMOS transistor Q1 is electrically connected to the ground terminal; the first end of the fourth resistor R4 is electrically connected to the power supply terminal; the second end of the fifth resistor R5 is electrically connected to the ground terminal; the source of the second NMOS transistor Q2 is electrically connected to the ground terminal, and the drain of the second NMOS transistor Q2 is electrically connected to the control circuit 30.

[0064] In this embodiment, the LED of the slot-type optocoupler is always in the on-state to continuously output light. When the light-collecting slot of the slot-type optocoupler is not blocked, the phototransistor of the slot-type optocoupler is always receiving the light signal output by the LED of the slot-type optocoupler, thereby opening the path between the power supply terminal and the switching circuit 12. At this time, the voltage output by the power supply terminal (i.e., the second optocoupler signal) will directly act on the first NMOS transistor Q1, thereby turning on the first NMOS transistor Q1. The drain of the first NMOS transistor Q1 is electrically connected to the second terminal of the fourth resistor R4 and the gate of the second NMOS transistor Q2, the source of the first NMOS transistor Q1 is electrically connected to the ground terminal, and the first terminal of the fourth resistor R4 is electrically connected to the power supply terminal. Therefore, when the first NMOS transistor Q1 is on, the gate voltage of the second NMOS transistor Q2 will be pulled low, thereby turning it off. The drain of the second NMOS transistor Q2 is electrically connected to the power supply terminal and the control circuit 30, and the source of the second NMOS transistor Q2 is electrically connected to the ground terminal. When the second NMOS transistor Q2 is off, the main control circuit receives a high-level signal output from the power supply terminal, i.e., the second detection signal. When the light-collecting slot of the slotted optocoupler is blocked, the phototransistor of the slotted optocoupler will not be able to receive the light signal output from the light-emitting diode of the slotted optocoupler, thereby cutting off the path between the power supply terminal and the switching circuit 12. At this time, the voltage output from the power supply terminal (i.e., the first optocoupler signal) will block the phototransistor of the slotted optocoupler, thereby causing the first NMOS transistor Q1 to turn off. The drain of the first NMOS transistor Q1 is electrically connected to the second terminal of the fourth resistor R4 and the gate of the second NMOS transistor Q2, the source of the first NMOS transistor Q1 is electrically connected to the ground terminal, and the first terminal of the fourth resistor R4 is electrically connected to the power supply terminal. Therefore, when the first NMOS transistor Q1 is off, the gate voltage of the second NMOS transistor Q2 will be pulled high, thus putting it in a conducting state. The drain of the second NMOS transistor Q2 is electrically connected to the power supply terminal and the control circuit 30, and the source of the second NMOS transistor Q2 is electrically connected to the ground terminal. When the second NMOS transistor Q2 is in the on state, the main control circuit will receive a low-level signal pulled low by the ground terminal, which is the first detection signal.

[0065] Furthermore, the prompting circuit 20 includes a sixth resistor R6 and a first light-emitting diode;

[0066] Wherein, the first end of the sixth resistor R6 is electrically connected to the power supply terminal, and the second end of the sixth resistor R6 is electrically connected to the anode of the first light-emitting diode; the cathode of the first light-emitting diode is electrically connected to the drain of the second NMOS transistor Q2 and the control circuit 30.

[0067] In this embodiment, the prompting circuit 20 is implemented using a visual prompting circuit 20. The visual prompting is achieved using a light-emitting diode (LED). The anode of the LED is electrically connected to the power supply terminal, the cathode is electrically connected to the drain of the second NMOS transistor Q2, and the source of the second NMOS transistor Q2 is electrically connected to the ground terminal. Therefore, the operating state of the prompting circuit 20 is adjusted according to the on or off state of the second NMOS transistor Q2. Specifically, when the second NMOS transistor Q2 is on, the power supply terminal connected to the anode of the first LED is connected to the ground terminal connected to the cathode of the first LED, thereby making the first LED work and outputting a lit prompt signal; when the second NMOS transistor Q2 is off, the power supply terminal connected to the anode of the first LED is turned off, thereby making the first LED stop working and outputting a turned-off prompt signal. The different operating states of the prompting circuit 20 indicate whether the interface of the high-frequency energy host is in the connected state. It should be noted that the first LED is the LED prompt light mentioned above, which serves as a prompt.

[0068] Alternatively, the first NMOS transistor Q1 and the second NMOS transistor Q2 can also be implemented using switching transistors with the same function.

[0069] Optionally, the high-frequency energy host further includes a pull-up circuit 40, the first end of which is electrically connected to the power supply terminal, and the second end of which is electrically connected to the control circuit 30.

[0070] In this embodiment, the pull-up circuit 40 is implemented using a resistor circuit. The first end of the resistor circuit is electrically connected to the power supply terminal, and the second end is electrically connected to the drain of the second NMOS transistor Q2. By setting the pull-up circuit 40, the pin connecting the switching circuit 12 and the control circuit 30 has an internal pull-up function, ensuring that the pin is at a high level when the second NMOS transistor Q2 is not turned on. This guarantees the stability of the control circuit 30's operation and its ability to determine the interface connection status.

[0071] Please see Figure 1 , Figure 3 and Figure 6 In one embodiment of the present invention, the high-frequency energy host further includes an identification component 50, which is electrically connected to the control circuit 30 and is used to receive the identification control signal and feed back the identification signal.

[0072] It's important to understand that the high-frequency energy generator can connect to various cutting tools, but the connection detection component 10 can only confirm whether a tool is connected to the high-frequency energy generator; it cannot identify the type of tool connected. Therefore, after a tool is connected, the high-frequency energy generator interface still needs to confirm the type of tool to output the corresponding energy control signal to the energy control board, thereby outputting energy corresponding to the tool type. This effectively avoids the problem of energy output under incorrect tool specifications; for example, the connection of counterfeit or substandard tools will prevent energy output.

[0073] In this embodiment, the identification component 50 can be implemented using RFID, short-range wireless communication, or encrypted identification chips. The identification component 50 is located near the interface to perform identification and confirmation when the tool holder is connected to the interface. The identification component 50 does not actively perform identification; instead, it operates by receiving identification control signals output from the control circuit 30 and feeding back an identification signal. The control circuit 30 confirms the type of tool connected to the high-frequency energy host by receiving the feedback identification signal from the identification component 50. Furthermore, the identification component 50 operates only after the access detection component 10 detects the tool connection, and does not perform a second identification as long as the access detection component detects the tool remains connected, avoiding the wear and tear caused by continuous identification. When the tool is disconnected from the interface of the high-frequency energy host, and the access detection component 10 detects the tool connection again, the identification component 50 will again receive the identification control signal output from the control circuit 30 and perform identification again to feed back an identification signal. The identification signal is located on the tool holder to facilitate the operation of the identification component 50.

[0074] Furthermore, the identification component 50 includes:

[0075] antenna;

[0076] The identification circuit has a first terminal electrically connected to the control circuit 30 and a second terminal electrically connected to the antenna. The identification circuit is used to receive the identification control signal and control the antenna to operate.

[0077] In this embodiment, the identification component 50 operates using a radio frequency identification (RFID) component. It acquires the identification signal sent by the sensing chip located on the tool holder by placing an antenna and identification circuit near the high-frequency energy host interface. When the identification circuit receives the identification control signal output from the control circuit 30, it outputs a corresponding signal to the antenna, causing the antenna to generate a radio frequency signal to the tool and receive the identification signal fed back by the tool's sensing chip. The identification component 50 outputs the received identification signal to the control circuit 30, allowing the control circuit 30 to confirm the identification signal, thereby achieving tool identification and preventing the high-frequency energy host from erroneously outputting energy due to tool problems.

[0078] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
