All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of this application is to provide a high frequency electrotome host computer for avoid the influence of the meticulous control of residual energy to high frequency electrotome energy output among the energy storage element.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Fig. 1 is a structural diagram of a high-frequency electrotome main unit according to an embodiment of the present application, and as shown in fig. 1, the main unit includes, in addition to a high-frequency energy generator 1 and a controller 2: the bleeder circuit 3, the bleeder circuit 3 is connected with energy storage element and controller 2 in the high-frequency energy generator 1;
the controller 2 outputs a control signal to control the bleeding circuit 3 to conduct to consume the energy stored in the energy storage element when receiving the bleeding signal.
The high-frequency electrotome mainly comprises a high-frequency electrotome main machine, an electrode 7, a pedal and other devices. In this embodiment, the physician typically uses a foot pedal to control the operation of the high frequency energy generator 1 in the main machine of the high frequency electric knife. As shown in fig. 1, when the high-frequency electric knife is operated in the operation state, the high-frequency energy generator 1 in the high-frequency electric knife main machine generates a high-frequency current, the high-frequency current flows to the monopolar electrode or the bipolar electrode 7, acts on the operation site of the patient 8 through the electrode, passes through the high-frequency current of the patient 8, and then flows back to the high-frequency energy generator 1 in the high-frequency electric knife main machine through the neutral electrode or the bipolar electrode 9, thereby forming an energy current loop.
Wherein, in the monopolar mode, the current from the high frequency energy generator 1 is passed through the patient 8 via the active conductor and the monopolar electrode 7 and then returned to the high frequency energy generator 1 via the neutral electrode 9 and its conductor. The heating effect of a high-frequency electric knife capable of destroying diseased tissue is not caused by a heating electrode or a knife head, like an electric cautery. It collects high-frequency current with high current density to directly destroy the tissue under the point of contact with the tip of the active electrode. Coagulation occurs when the temperature of the tissue or cells in contact with or adjacent to the active electrode rises to denature proteins in the cells, the precise surgical effect being determined by the waveform, voltage, current, type of tissue and shape and size of the electrode.
In the bipolar mode, high-frequency electric energy is provided for body tissues through two tips of a bipolar electrode, so that blood vessels between two ends of the bipolar electrode are dehydrated and coagulated, and the aim of stopping bleeding is fulfilled. The action range of the device is limited between two ends of the electrode, the damage degree and the influence range to body tissues are far smaller than those of a single-pole mode, and the device is suitable for sealing small blood vessels (the diameter is less than 4mm) and oviducts. Therefore, the bipolar mode is widely used in more delicate operations such as brain surgery, microsurgery, ophthalmology, gynecology and obstetrics, and hand surgery.
The high-frequency energy generator 1 mainly comprises a power supply conversion circuit 4, a high-frequency power amplification circuit 5, a filter circuit 6 and the like, wherein the circuits comprise energy storage elements such as a transformer, an inductor, a capacitor and the like, when the high-frequency electrotome needs to stop or reduce energy output in the operation process, the energy storage elements also store energy applied at the previous moment, and the stored residual energy can be transmitted to the operation position of a patient 8 through an electrode to influence the operation effect. In the embodiment, the bleeder circuit 3 is connected to the energy storage element, and it can be understood that, since there are a plurality of energy storage elements and the positions may be dispersed, there may also be a plurality of bleeder circuits 3 for better bleeder effect, which may be connected to each energy storage element or to a single energy storage element with more stored energy. It can be directly connected with the energy storage element as the bleeder circuit 3 of the energy storage element; the bleeder circuit 3 may be connected to a circuit such as the power conversion circuit 4 or the high-frequency power amplifier circuit 5, and then may be used as the entire circuit.
In this embodiment, the bleeding circuit 3 is further connected to the controller 2, and the controller 2 outputs a control signal to control the bleeding circuit 3 to be turned on to consume the energy stored in the energy storage element when receiving the bleeding signal. In the above-described embodiment, the doctor usually controls the operation of the high-frequency energy generator 1 in the main machine of the high-frequency electric knife by using the pedals. The doctor operates the high-frequency power generator 1 by depressing the foot pedal, and stops the operation of the high-frequency power generator 1 when the foot pedal is released. Therefore, the discharge signal in this embodiment may be a signal when the surgeon releases the pedal, so as to discharge the residual energy after the high frequency energy generator 1 stops working. Of course, the release signal may be in the form of a button, paddle, etc. that is independently provided and the doctor presses to release the energy.
The high-frequency electrotome main machine provided by the application comprises a high-frequency energy generator and a controller, and further comprises a discharge circuit, wherein the discharge circuit is connected with an energy storage element and the controller in the high-frequency energy generator. The controller outputs a control signal to control the conduction of the bleeder circuit to consume the energy stored in the energy storage element under the condition of receiving the bleeder signal. Compared with the prior art, the energy in the energy storage element in the high-frequency energy generator can not be timely dissipated to further influence the fine control energy output of the high-frequency electrotome, and by means of the technical scheme, the release circuit is additionally arranged, when the controller receives a release signal, the release circuit is controlled to be conducted, so that the energy in the energy storage element is consumed through the release circuit, the influence of energy residue on the work of the high-frequency electrotome is avoided, and the fine control of the high-frequency electrotome on the energy output is guaranteed.
It will be appreciated that the bleeding circuit 3 functions to discharge the energy in the energy storage element upon receiving a bleeding signal, and therefore, in a specific implementation, the working state of the bleeding circuit 3 should be actively controllable by the physician.
Therefore, in the present embodiment, the bleeder circuit 3 includes a bleeder resistor and a switch.
The bleeder resistor plays a role in consuming energy in the energy storage element, the resistor can be a single resistor or a combination of several connected resistors, and the resistance value of the resistor is determined according to the amount of energy stored in the energy storage element and the energy consumption rate. The switch in this embodiment determines the operating state of the bleeding circuit 3, and the switch may be a controllable device such as a transistor and a relay, or a combination thereof.

In the specific implementation, when the control signal output by the controller 2 is in a state of continuous output, if the output of the control signal is not stopped, the resource is wasted, and the subsequent use of the high-frequency electrotome is affected.
Therefore, on the basis of the above embodiment, in this embodiment, the high-frequency electrotome main body further includes: the voltage detection device is connected with the bleeder resistor and the controller 2;
the controller 2 stops the output of the control signal when the voltage detection device detects that the voltage of the bleed-off resistor is zero.

On the basis of the above embodiment, the high-frequency electrotome main unit provided by this embodiment further includes: and the prompting device is connected with the controller 2 and is used for giving out a prompt when the controller 2 stops outputting the control signal.
It can be understood that, in the concrete use, the doctor can't know whether the residual energy stored by the energy storage element has been consumed by the bleeder resistor, therefore, this embodiment adds the suggestion device, and this suggestion device can send the suggestion when the controller stops control signal's output, namely when the voltage of bleeder resistor returns to zero to remind the doctor that the residual energy is released and is finished. The prompt may be in the form of an indicator light, a prompt sound, a combination thereof, or the like, and the present embodiment is not limited thereto.
It will be appreciated that in particular implementations, the bleed circuit 3 is required to bleed residual energy from the energy storage element when the hf electrotome is not in operation, in order to avoid injury to the patient 8. At the same time, however, the discharge may be performed during the operation of the high-frequency electrotome, so as to reduce the energy output by the high-frequency energy generator 1. Therefore, the bleed-off signal in this embodiment includes: an energy output lowering signal or an energy output stopping signal.
The energy reduction signal represents that the energy of the energy storage element is not required to be completely discharged, and the energy is only required to be reduced to the required energy so as to ensure the operation. And the energy output stop signal indicates that the energy of the energy storage element needs to be completely discharged so as to avoid the damage of the residual energy to the patient.
In the above embodiment, it is described that the bleeding circuit 3 may be a bleeding circuit 3 connected to a respective energy storage element in the high-frequency energy generator 1 as a certain energy storage element; the bleeder circuit 3 may be connected to a circuit such as the power conversion circuit 4 or the high-frequency power amplifier circuit 5, and then may be used as the entire circuit.
In the present embodiment, each bleeder circuit 3 is connected to each energy storage element in the high-frequency energy generator 1 in a one-to-one correspondence.
It can be understood that the bleeder circuit is connected for every energy storage element, and the residual energy can be ensured to be discharged completely, so that the accuracy of the operation is greatly guaranteed, and the injury to the patient is avoided.
In concrete implementation, the doctor needs attention to concentrate highly during operation, easily tired to personnel are more in the operating room, and in order to avoid mistake touching and lead to bleeder circuit 3 to switch on, influence the going on of operation, the high frequency electrotome host computer that this embodiment provided still includes: and the alarm device is connected with the controller 2, and if the controller 2 continuously receives the release signals for the preset times within the first preset time, the first alarm signal is sent out to enable the alarm device to work.
It can be understood that, during the operation, the doctor needs to turn on the bleeder circuit 3 frequently, therefore, the first preset time in this embodiment should not be too long, and the normal operation is not treated as a false touch. Meanwhile, the time is not too short, otherwise, the detected times cannot reach the preset times, and the possibility of missing report is caused. In particular, the setting may be made according to the rate at which the bleed off resistor dissipates energy. If the bleed-off resistor re-receives the bleed-off signal after receiving the bleed-off signal while the residual energy has not been consumed by the bleed-off resistor, a false touch event may occur.
The high-frequency electrotome host provided by the embodiment sends out the first alarm signal to enable the alarm device to work when the controller continuously receives the release signal of the preset times within the first preset time, so that the energy loss caused by mistaken touch is avoided, and the operation is influenced.

In a specific implementation, when the bleeder circuit 3 exhausts the energy of the energy storage element, its current returns to zero, but when the bleeder circuit 3 is open, its current is also zero. The physician cannot know whether the bleeding circuit 3 bleeds the residual energy. The high-frequency electrotome main machine provided by the embodiment detects the current of the bleeder circuit through the current detection device, and if the controller receives the bleeder signal, the current of the bleeder circuit is continuously zero within a second preset time, which indicates that the bleeder circuit is broken, so that a second alarm signal is sent to enable the alarm device to work to inform a doctor.
It should be noted that the second alarm signal in this embodiment may be the same as or different from the first alarm signal in the above-mentioned embodiment. Of course, the second alarm signal should be different from the first alarm signal in order to enable the physician to know the specific alarm content accurately.
