The present disclosure relates to the technical field of medical devices, and in particular, to an ultrasonic scalpel, an energy instrument for surgical use, and a control method therefor.
Ultrasonic scalpel provides ultrasonic energy in various endoscopic surgery and conventional surgery which is mainly used for hemostatic separation of soft tissue and tissue condensation. With the popularization of minimally invasive surgery, ultrasonic scalpel has become a conventional surgical instrument and is widely used. The ideal ultrasound scalpel needs to meet the following requirements simultaneously:
Firstly, it is necessary to have the safety of surgical operations. In traditional ultrasonic scalpel design, a trigger button is provided, which means that when the trigger button is pressed, the ultrasound generator is switched on to output energy, and once the trigger button is released, the ultrasound generator will be immediately switched off to stop the energy output. This can effectively reduce the risk of the ultrasound scalpel accidentally touching non surgical target human tissue in the energy excitation state, and avoid unnecessary injure, therefore, most surgeons have been trained and developed a hand-controlled mode of using trigger buttons;
Secondly, it is necessary to reduce the cost of existing ultrasound scalpels. Currently, in order to save costs, ultrasound scalpels are not used as disposable devices, so strict disinfection of the ultrasound scalpel heads is necessary to ensure sterility and safety;
Thirdly, it is necessary to have the convenience and stability of ultrasonic scalpel operation. The handheld portion of an ultrasonic scalpel usually comprises a trigger button for controlling energy output, an operation button for controlling the rotation/bending/opening and closing of the functional head, etc. When using such instrument, surgeons not only need to operate the trigger button and other different buttons, but also require different finger forces, therefore, there are high requirements for coordination between different fingers. Therefore, many doctors are accustomed to using foot switches to replace the operation that originally required one or several fingers of the surgical operator, to reduce the burden on the fingers of the surgical operator, which reduces the force and coordination requirements on the fingers of the surgical operator's hands, and makes his/her control of the instrument more stable.
The technology of ultrasonic scalpels has evolved to the point that the hand-controlled mode of trigger button in conjunction with the foot-operated mode of foot switches has become a universally accepted way of performing surgical procedures, to the point where even some doctors rely on foot switches to be able to perform their procedures at a high level.

As stated in the Background, many energy instruments for surgical use provide foot switches for surgical operators to select and use, to mitigate the finger burden and reduce finger coordination requirements. However, the foot switches bring at least the following defects:
First, due to that a doctor only needs one foot to control the foot switch, most of the weight of the body needs to be borne by the other leg, considering that some surgeries take a long time, with some lasting more than ten hours, the frequent surgical work throughout the year makes the load-bearing leg (the other leg other than the leg stepping on the foot switches) of the doctor who is accustomed to using foot switches very pone to fatigue and even damage (including muscles, joints, varicose veins, etc.);
Second, not every surgeon is accustomed to using foot switches, but as long as a hospital has one surgeon who needs to use them, the hospital needs to purchase them, the market price of a foot switch is even more expensive than an energy instrument for surgical use, leading to a significant increase in the unit cost of procurement, and operating room equipment needs to be regularly disinfected and maintained, using foot switches will increase the management costs;
Third, a plurality of instruments may be controlled by foot switches during surgery, which may result in the surgeons having more than one foot switch under their feet, when there are too many things on the ground, especially during surgery when the surgeons and nurses are highly focused on the surgery and neglect to observe the ground, they are prone to tripping when walking;
Fourth, if there are multiple surgical procedures where different surgeons have foot switch needs, and in case that it needs to take turns to use the foot switch, if the surgical schedule makes the needs of the foot switch occur at the same time and conflict with each other, it can seriously affect the qualities of surgeries or disrupt existing surgical schedules.
However, due to the fact that the combination of the scalpels and the foot switches has become an inherent mindset, it is not easy to think of changing this pattern habit that has been used for decades, even many experienced surgeons cannot perform surgeries smoothly without foot switches, therefore, even though poor standing posture during prolonged surgeries throughout the year puts a hug burden on their legs, they still cannot give up the using of foot switches.
In one embodiment of the present disclosure, an ultrasonic scalpel is provided, which comprises a handheld component and a control module, the handheld component is provided with a trigger button, the trigger button is connected to an input terminal of the control module;
The output terminal of the control module is electrically connected to the energy generating apparatus directly or indirectly, in this embodiment, the two is connected via an electronic controllable switch, or may be connected directly via a wire in other embodiments, in the case of being connected via an electronic controllable switch, if the trigger button is pressed, the control module controls the electronic controllable switch to switch on, and if the trigger button is released, the control module controls the electronic controllable switch to switch off;
Referring to
in response to a first trigger signal triggered by an external switching action, the control module switches the working mode of the trigger button to: each time the trigger button is pressed, the control module controls the electronic controllable switch to change the current switching state, and the changed switching state is maintained until the trigger button is pressed again, for example: on the premise of switching to this working mode, the energy instrument for surgical use is currently in standby mode (the electronic controllable switch is off). If the trigger button is pressed, the control module controls the electronic controllable switch to switch on, at this moment the operating system of the energy instrument for surgical use closes the circuit, the energy generating apparatus continuously outputs energy to the handheld component, even if the trigger button is released, the energy output is maintained continuously; the control module will not control the electronic controllable switch to switch off until the trigger button is pressed again, at this moment the operating system cuts off the circuit, at this moment the energy generating apparatus stops outputting energy to the handheld component, and returns to the standby mode.
In another embodiment of the present disclosure, the control module is electrically connected to the energy generating apparatus directly via a wire rather than an electronic controllable switch, that is, the control module may directly drive the energy generating apparatus, if the trigger button is pressed, it drives the energy generating apparatus to output energy; if the trigger button is released, the energy generating apparatus will not be driven, and accordingly, the energy generating apparatus will stop outputting energy. The control module is configured to execute the following procedure: in response to a first trigger signal triggered by an external switching action, each time the trigger button is pressed, the control module controls the energy generating apparatus to change the current ultrasonic energy output state, and the changed ultrasonic energy output state is maintained until the trigger button is pressed again, for example, if the energy generating apparatus is currently not outputting energy, and if the trigger button is pressed at this moment, even if the trigger button is released at this moment, the energy generating apparatus will continue to output energy, and the energy generating apparatus will not stop outputting energy until the trigger button is pressed again; if the energy generating apparatus is expected to continuously output energy again, it only needs to press the trigger button again, and repeat the process.
In another embodiment of the present disclosure, the control module is electrically connected to the energy generating apparatus via a power board rather than the electronic controllable switch, if the trigger button is pressed, the control module controls the power board to send a drive instruction to the energy generating apparatus, and if the trigger button is released, the control module controls the power board to stop sending the drive instruction; the control module is configured to execute the following procedure: in response to the first trigger signal, each time the trigger button is pressed, the control module controls the power board to change the current drive instruction output state, and the changed drive instruction output state is maintained until the trigger button is pressed again, wherein, the drive instruction output state is divided into a state of sending the drive instruction and a state of stopping sending the drive instruction, for example, if the energy generating apparatus is currently not outputting energy, and if the trigger button is pressed at this moment, even if the trigger button is released at this moment, the power board will still continue to send the drive instruction to the energy generating apparatus, to cause it to continue to output energy, and the power board will not stop sending the drive instruction to the energy generating apparatus, and the energy generating apparatus will not stop outputting energy accordingly until the trigger button is pressed again; if the energy generating apparatus is expected to continuously output energy again, it only needs to press the trigger button again, and repeat the process.
The handheld component of this embodiment can achieve the “foot mode” without being connected to a foot switch, the “foot mode” herein does not refer to the mode of controlling the operation of the energy generating apparatus by stepping on a button on a foot switch, but rather to the traditional working logic (working mode) of changing the trigger button through the first trigger signal or a second trigger signal triggered by an external release switching action, so that users can continuously excite energy without having to keep pressing the trigger button with their fingers all the time, as if stepping on the foot switch.

Referring to
In this way, it only needs to connect the two conductive wires of the power cord to the first elastic power connection piece 13a and the second elastic power connection piece 13b respectively, then the power cord can be led from the lower portion of the handle shell 11 to connect to the power supply, in this way, in the rotation process of the transducer assembly 12 about its own axis in the handle shell 11, the power cord does not rotate along with it, such that a series of problems of the large arm force and easy fatigue, and knotting of the power cord, etc. caused by the power cord extending from the rear portion of the handle shell 11 are avoided.
The ultrasonic scalpel of this embodiment may also be switched back to its previous working mode through a second trigger signal triggered by an external release switching action, specifically, the control module is further configured to execute the following procedure:
in response to the second trigger signal, the control module restores the working mode of the trigger button to the working mode before switching; wherein, the external release switching action is the same as or different from the external switching action.
The specific operation of switching the working mode according to the first trigger signal and the second trigger signal mentioned above is as follows (as the switching principle of the first trigger signal and the second trigger signal is the same, the following only takes the external switching action used to trigger the first trigger signal as an example for explanation):
The first situation is that there is only one trigger button provided on the handheld component, where the trigger button can be used to trigger the control module to switch modes, however, it should be noted that the trigger button itself has a press/release operation corresponding to the control energy output/interruption, therefore, it is necessary to adopt a method of non-clicking or non-long pressing the trigger button, such as double clicking or multi clicking the trigger button within a predefined short time;
The second situation is that there are multiple trigger buttons provided on the handheld component, or as shown in
The third situation is that a new button designed specifically for this mode switching can be used to achieve trigger mode switching, such as a mode switching button similar to the function key, or a dial switch that switches to the first working mode when flipped to a first position, or to the second working mode when flipped to a second position.
In an embodiment of the present disclosure, an energy instrument for surgical use is provided, which has a first working mode and a second working mode, and the embodiment of the present disclosure can be applied in the field of ultrasonic scalpels, such as soft tissue cutting and coagulation scalpels and ultrasonic osteotomes; it can also be applied in the field of laser knives, electric knives, or other surgical scalpels.
The energy instrument for surgical use comprises an energy generating apparatus, a handheld component, and a control module, which are described as follows:
The energy generating apparatus is configured to generate energy, and if it corresponds to the application scenario of the ultrasonic scalpel, the energy generating apparatus is an ultrasonic generator; if it corresponds to the application scenario of the laser knife, the energy generation apparatus is a laser generator; if it corresponds to the application scenario of the electric knife, the energy generation apparatus is an electrical signal generator.
The present disclosure is not limited to the three types of surgical energy instruments mentioned above, but can also be used for other medical instruments that can be connected to foot switches, for example, if the energy instrument for surgical use is a medical smoking device, the energy generating apparatus is an air pump, and the medical smoking device is used in the operating room to keep the surgical environment in a smoke-free state;
the energy instrument for surgical use is a vacuum suction apparatus, and the energy generating apparatus is a vacuum pump;
the energy instrument for surgical use is an infusion pump, and the energy generating apparatus is an infusion pump;
the energy instrument for surgical use is a manipulator with an elbow joint rotation, and the energy generating apparatus is a motor;
the energy instrument for surgical use is a monopolar electrocoagulation pencil or bipolar electrocoagulation forceps, and the energy generating apparatus is an electrical signal generator, and so on, which will not enumerate here. There are two existing buttons for the above products, namely a high-power button and a low-power button, the original modes are to close the circuit when being pressed and open the circuit when being released; using the scheme of this embodiment to switch the working mode, for example, pressing and holding the high-power and low-power buttons simultaneously for 2 seconds (this method is only an example) can switch to the foot mode, and pressing the high-power button again will continue to output high power, and the high power output will not stop until the high-power button is pressed again; the same applies to the low-power button.
The handheld component is electrically connected to the energy generating apparatus via an electronic controllable switch, the handheld component is provided with one or more operation buttons, wherein at least one of the operation buttons is the trigger button 14; taking ultrasonic scalpels as an example, different models of ultrasound scalpels are provided with different operation buttons on the handles thereof, for example, some are provided with one trigger button 14, while others are provided with corresponding trigger buttons 14 for different functions (such as cutting or coagulation) or different powers, in addition to the trigger button 14, there may also be other operation buttons 15, such as a function button (used to select cutting or coagulation functions), a power shift button (used to adjust the power), etc. The present disclosure does not limit the type of buttons on the handheld component, except for the trigger button 14, or whether there are other operation buttons 15 other than the trigger button 14, and moreover, the present disclosure does not limit the arrangement relationship between the energy generation apparatus and the handheld component to an integrated arrangement manner or the arrangement mode of the energy generation apparatus being inside the handheld component.
An input terminal of the control module is electrically connected to the operation buttons, and an output terminal thereof is electrically connected to the electronic controllable switch; the control module controls the energy instrument for surgical use to switch between the first working mode and the second working mode according to a predefined first trigger signal and a predefined second trigger signal, wherein the first trigger signal and the second trigger signal may be the same action or may each be defined as different actions, and below, the first working mode and the second working mode are first explained, and then how to switch between the two different working modes is explained.
The two working modes are shown in
The first working mode is the normal mode (hand-controlled mode), and the control logic for a single trigger button of the energy instrument for surgical use standby in the normal mode is: if the trigger button is pressed, the control module controls the electronic controllable switch to switch on, at this moment the instrument closes the circuit, and the energy generating apparatus continuously outputs energy to the handheld component; if the trigger button is released, the control module controls the electronic controllable switch to switch off, at this moment the instrument cuts off the circuit, at this moment the energy generating apparatus stops outputting energy to the handheld component, and returns to the standby mode. That is, under the premise of powering on the system, only during the time period when the trigger button is pressed, the energy instrument for surgical use is in working mode, and other time periods are in standby mode.
The second working mode is the “foot mode”, and the control logic for a single trigger button of the energy instrument for surgical use standby in the foot mode is: a single press of the trigger button will change the state of the energy instrument for surgical use before and after the press, taking the energy instrument for surgical use being currently in standby mode (the electronic controllable switch is off) as an example, if the trigger button is pressed, the control module controls the electronic controllable switch to switch on, at this moment the instrument closes the circuit, the energy generating apparatus continuously outputs energy to the handheld component, even if the trigger button is released, the energy output is maintained continuously; the control module will not control the electronic controllable switch to switch off until the trigger button is pressed again, at this moment the instrument cuts off the circuit, at this moment the energy generating apparatus stops outputting energy to the handheld component, and returns to the standby mode.
It should be noted that the definition of the second working mode as the “foot mode” refers to this new control mode that can reduce the requirements for force and coordination on the hands of surgeon without the need for a foot switch, achieving a stable control level that is basically the same as using a foot switch, rather than referring to the mode achieved by using a foot switch. However, the present disclosure does not exclude the possibility of using a foot switch, and only means that finger coordination without the use of a foot switch can be basically achieved or even exceeded that when using a foot switch.
Below is an explanation of how to switch between two different working modes in various different embodiments:
In one embodiment of the present disclosure, one or more of the operation buttons are configured to act in accordance with a predefined operation to trigger the control module, including but not limited to the following trigger methods:
clicking or long pressing one of the operation buttons other than the trigger button; double or multiple clicking one or more of the operation buttons;
pressing multiple operation buttons simultaneously;
pressing multiple operation buttons successively according to a predefined order;
flipping a dial switch in the operation buttons.
In summary, the trigger button can be used to trigger the control module to switch modes, however, it should be noted that the trigger button itself has a press/release operation corresponding to the control energy output/interruption, therefore, it is necessary to adopt a method of non-clicking or non-long pressing the trigger button, such as double clicking or multi clicking the trigger button within a predefined short time; the control module can also be triggered to activate the foot mode using a single operation button or a combination of multiple operation buttons other than the trigger button on the handle, such as double clicking (multi clicking) the function key or power shift button, or simultaneously pressing two or three of the function key, the power shift button and the trigger button, or according to a predefined pressing order of the function key—power shift button—trigger button or pressing orders in other free combinations (not limiting a certain button to single sorting and usage); a new button designed specifically for this mode switching can also be used to achieve trigger mode switching, such as a mode switching button similar to the function key, or a dial switch that switches to the first working mode when flipped to a first position, or to the second working mode when flipped to a second position.
In one embodiment of the present disclosure, the control module is connected to an external human-machine interaction device through a wired or wireless mode, and an instruction is input to the control module through the human-machine interaction device to trigger the control module. For example, a manner that the control module is in wired connection to the touch screen, and through the operation on the touch screen, the corresponding normal mode or foot mode can be controlled and activated; an application program (App) on a mobile terminal that is wirelessly connected to the control module can also be chosen and used to switch between the normal mode and the foot mode.
The above implementations through the operation buttons and the human-machine interaction device can be independently implemented, but it is not ruled out that the above different implementation schemes can be integrated into the system of the same energy instrument for surgical use.
In one embodiment of the present disclosure, after being powered on, the energy instrument for surgical use is initialized to the first working mode, when the first trigger signal triggers the control module, the control module controls the system to switch to the second working mode, which activates the foot mode; when an external canceling trigger action is received, the control module controls the system to switch to the first working mode, namely returns to the normal mode. Obviously, the initialization state can also be set to the second working mode, and a preset operation action of the operation button for switching from the first working mode to the second working mode can be the same or different from a preset operation action of the operation button for switching the system from the second working mode to the first working mode.
The present disclosure provides an energy instrument for surgical use which can switch the working modes, which takes into account the traditional working mode that when the trigger button on the handle of the energy instrument for surgical use is pressed, the instrument outputs energy, and if the trigger button is released, the instrument stops outputting energy, and which, without the need for a foot switch, provides a working mode of foot mode that changes the control mode of the trigger button on energy output, the control method (mode switching operation) comprises the following steps:
in the case that the energy instrument for surgical use is powered on, inputting a predefined trigger action to redefine a control mode of the trigger button on energy output to: no energy output in an initial state, and if the trigger button is pressed for the first time, the instrument outputs energy, and the instrument will not stop outputting energy until the trigger button is pressed again;
the trigger button will not restore the initial control mode on energy output until the energy instrument for surgical use is disconnected from the power supply or a predefined trigger action is input.
The embodiment of this control method belongs to the same concept as the above embodiments of the energy instruments for surgical use, and the above embodiments of the energy instruments for surgical use are incorporated herein into this manipulation method embodiment by reference in their entireties.
The traditional working mode of the trigger button on the energy instruments for surgical use is to press to close the circuit, and release to open the circuit, and this traditional normal mode is already in line with the usage habits of surgeons, especially since the surgical ability of surgeons is gradually accumulated based on previous surgical experience, this traditional design cannot be canceled; secondly, from an ergonomic perspective, the normal mode (hand-controlled mode) is a relatively safe design, and if the blade of the instrument accidentally touches human tissue that is not a surgical target during energy exciting, it may cause unnecessary damage.
In the traditional normal mode that needs to be preserved, during the stage of continuous energy output in an operation, the scheme of this embodiment can be used to switch the working mode of the trigger button through external trigger switching operation, so that the surgical practitioner does not need to keep pressing the trigger button with their fingers, nor does they need to keep stepping on the foot switch, which avoids damage or pain to the finger bones caused by the surgeon's constant pressing of the trigger button during a prolonged operation period, and avoids the leg burden caused by the surgeon's single foot (the foot that has not pressed the foot switch) supporting the body weight for a long time, and which at the same time can achieve finger coordination that is basically consistent with when using the foot switch.
It should be noted that herein, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, terms “comprising”, “including”, or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, item, or device that includes a series of elements not only includes those elements, but also includes other elements that are not explicitly listed, or also include elements inherent in such a process, method, item, or device. Without further limitations, elements limited by the statement “comprising a . . . ” do not exclude the existence of other identical elements in the process, method, item, or device that includes the elements.
The above are only specific implementations of the present application. It should be noted that, for those ordinary skilled/of ordinary skill in the art, any improvements or modifications can be made without depart from the technical principle and conception of the present application, and shall be covered by the protective scope of the present application.
