technical field

The invention relates to the technical field of staplers, in particular to an electric stapler and a power display method thereof.

Background technique

It is well known that intracavitary cutting staplers have been widely used in intracavitary surgery such as the abdominal cavity. The doctor operates the stapler into the body to cut and sew the tissue. The traditional stapler is a mechanical stapler, and the user's manual operation is used as power to drive the stapler. In recent years, more labor-saving and easy-to-operate electric staplers have appeared, using a battery-driven motor to drive the stapler. Due to the use of batteries, providing a battery level indication on the stapler enables better human-machine interaction. The traditional battery power display method is the voltage detection method, which directly detects the voltage of the battery or battery pack, etc., and then compares it with the preset threshold of the battery or battery pack to determine the current power of the battery or battery pack, and then use it. Different forms of lights to indicate the power level. Since the stapler is a one-time device in the medical device, one is discarded after the operation, therefore, the disposable battery is selected. If the traditional battery indicator method is applied to the electric stapler, it will have the following shortcomings:

1. Due to the weak discharge capacity of the disposable battery, when the motor of the electric stapler is used with a large load, the voltage drop of the battery is very large. For example, when the electric stapler cuts thick tissue under a fully charged battery, the electric stapler will indicate the power of the electric stapler. The light will appear jumping light directly. When the doctor uses the electric stapler for surgery, especially during the firing process, the electric stapler frequently jumps the light, which affects the doctor's firing process, that is, the light jumps during firing. The doctor may think that the electric stapler will stop firing when it is out of power , and then the battery indicator light returned to normal display, and the doctor fired again, which was a very poor experience for the user. Secondly, the power indicator light of the electric stapler can not reflect the real power of the battery. Only when the electric stapler is static and uncut can the voltage of the battery indicate the current real power of the battery.

2. After the load in the electric stapler stops, due to the characteristics of battery voltage recovery, the power indicator light may rise rapidly or jump back and forth.

To sum up, in the electric stapler using disposable batteries in the prior art, when the motor is used, the power display jumps over the light or jumps back and forth. Therefore, it is necessary to develop a more accurate power display method to solve the above problems. question.

Since the stapler is a one-time instrument in medical equipment, it is discarded after one operation. Therefore, in order to reduce the cost, ordinary electric staplers usually use disposable batteries. There is a situation where the power display skips the light or jumps back and forth. Therefore, especially in the special application environment where the electric stapler adopts a primary battery, in order to solve the problem of inaccurate power display when the motor is in use, as shown in FIG. 1 , this embodiment provides an electric stapler and a power display method thereof, The electric stapler includes a battery unit 600, and the battery unit 600 may include a primary battery for supplying electrical energy, and of course may also be a rechargeable battery. The battery unit 600 is detachably mounted on the electric stapler, or the battery unit 600 is located in the main body of the electric stapler and cannot be detached. The electric stapler may further include: a jaw assembly, a cutting knife assembly, a motor 100 , a motor state detection unit 400 , keys, a key detection unit 700 , a battery state detection unit 200 , a power display unit 300 and a control unit 500 .

Wherein, as shown in FIG. 1 , the motor 100 is electrically connected to the battery unit 600 , which is used for receiving the electric energy of the battery unit 600 to operate, and the motor 100 drives the jaw assembly to perform actions and drives the cutting knife assembly when running. perform an action. For example, performing an action may include jaw opening, jaw closing, firing, retracting, and the like.

As shown in FIG. 1 , the battery state detection unit 200 is used to detect the state parameters of the battery unit 600 . The state of the power display unit 300 indicates the power of the battery unit 600 . The control unit 500 may be electrically connected to the motor state detection unit 400 , the battery state detection unit 200 , the power display unit 300 and the like. In one embodiment, the control unit 500 is used to determine whether the motor 100 is running, to receive the state parameter of the battery unit 600 , and to control the state of the power display unit 300 at least according to the state parameter of the battery unit 600 . The control unit 500 may also obtain the electric quantity parameter of the battery unit 600 according to the state parameter of the battery unit, and control the state of the electric quantity display unit 300 according to the electric quantity parameter of the battery unit 600 . When judging that the motor 100 is running, the control unit 500 controls the state of the power display unit 300 to keep the last state of the motor 100 before the running state, that is, the state of the power display unit is not updated in real time. As feasible, the motor state detection unit can be used to determine whether the motor 100 is running.

In another implementation manner, the control unit 500 may detect a motor control signal sent by a key capable of controlling the motor, and control the motor 100, so as to receive the state parameters of the battery unit 600 and control all the battery cells according to the state parameters of the battery. The state of the power display unit 300 is described. The control unit 500 obtains the state parameter of the battery unit 600, obtains the electric quantity parameter according to the state parameter of the battery unit 600, and then controls the state of the electric quantity display unit 300 according to the electric quantity parameter. When it is determined that the motor control signal given by the button is the motor start signal, the control unit 500 controls the state of the power display unit 300 to keep the last state of the motor 100 before the running state, that is, the state of the power display unit 300 is not changed. for real-time updates.

As shown in FIG. 1 , the motor state detection unit 400 is used to detect the state parameters of the motor 100 , and the control unit 500 receives the state parameters of the motor and determines whether the motor 100 is running according to the state parameters of the motor. The state parameters of the motor 100 may include the current of the motor 100, the voltage difference between the positive electrode and the negative electrode of the motor 100, the rotational speed of the motor 100, etc. These state parameters can reflect whether the motor 100 is running. Such parameters are used to determine whether the motor 100 is running. The battery state detection unit 200 may detect voltage parameters across the battery unit 600 and send the detected voltage across the battery unit 600 to the control unit 500 . When the battery cell is discharged, the power decreases, and the voltage of the battery cell also decreases, and the voltage can reflect the power of the battery cell. The control unit 500 can obtain the electric quantity parameter of the battery unit 600 by converting the voltage at both ends of the battery unit 600 , and then controls the state of the electric quantity display unit 300 according to the electric quantity parameter of the battery unit 600 . Of course, the battery state detection unit 200 can also detect other state parameters of the battery that can reflect the power, so that the control unit 500 can obtain the power parameters of the battery unit 600 and control the state of the power display unit, such as the charge transfer amount of the battery, usage time, etc. Wait.

As practicable, the power display unit 300 may include a plurality of indicator lights. When the power of the battery unit 600 is more, the number of the indicator lights is green; when the power of the battery unit 600 is about to be insufficient, the indicator lights up red or bright. glows red and flashes. Of course, the power display unit 300 may also adopt other manners, which are not limited in this application. For example, the power display unit 300 can also display a display screen to indicate the power of the battery unit 600 by displaying percentage or length.

In order to enable the user to clearly know the remaining power of the battery unit 600, in a preferred implementation, FIG. 2 shows the detection of the power of the battery unit 600 of the electric stapler in the embodiment of the present invention, and through The display unit displays the flow chart of the power of the battery unit 600 at this time. As shown in FIG. 2 , there can be five indicator lights. When the power of the battery unit 600 is greater than or equal to 80%, the five indicator lights light up green; when the battery unit 600 When the power of the battery unit 600 is less than 80% and greater than or equal to 60%, the four indicators light up green; when the power of the battery unit 600 is less than 60% and greater than or equal to 40%, the three indicators light up green; when the power of the battery unit 600 is less than 40% %, greater than or equal to 20%, 2 indicators light up yellow; when the power of the battery unit 600 is less than 20%, greater than or equal to 10%, one indicator light lights up red; when the power of the battery unit 600 is less than 10%, 1 One indicator lights up red and flashes to give an alarm. In the above manner, the power of the battery unit 600 is illuminated in different forms under different remaining levels, so that the user can clearly know the specific range of the remaining power of the battery unit 600, so that it is possible to estimate the power of the electric stapler. time to continue using.

As shown in FIG. 2 , when the electric stapler obtains power from the battery unit 600 for the first time, it generally takes about 100ms after the power of the battery unit 600 is stabilized. Of course, the waiting time can be any time longer than the above-mentioned time. The battery state detection unit 200 detects the state parameters of the battery unit 600 , the control unit 500 receives the state parameters of the battery unit 600 and obtains the power of the battery unit 600 according to the battery state parameters, and controls the power display unit 300 according to the power of the battery unit 600 state, so as to achieve real-time update of the state of the power display unit 300 . Real-time update refers to allowing changes over time, that is, during real-time update, if the state parameters of the collected battery cells change, the state of the updated power display unit 300 may change, if the collected state parameters of the battery cells does not occur, the state of the updated power display unit 300 may be the same as before. If the power parameters of the battery unit 600 are changed after calculation, the updated state of the power display unit 300 may be changed. If the state parameters of the unit 600 have not changed, the updated state of the power display unit 300 may be the same as before. For example, in the embodiment in which the power display unit 300 includes a plurality of indicator lights, the number of the lights on the power display unit 300 indicates the state of the battery power. At present, the three indicators light up in green, and when the real-time update is performed, It may happen that 4 lights are on, or 3 lights may continue to be on. The change of the state of the power display unit 300 during the real-time update must be caused by the change of the state parameter of the front-end battery. When the battery unit is powered for the first time, the motor has not yet worked and is in a state of stop. The battery unit only provides a small current to some low-power circuits of the stapler. The voltage of the battery unit can well reflect the remaining power of the battery, so the state of the battery unit The parameter can be selected as a voltage parameter. Stop running means that the motor does not run, including the motor does not run when the battery is just powered, and the motor does not run after the motor stops after running.

When judging that the motor 100 is running, the control unit 500 controls the state of the power display unit 300 to keep the last state of the motor 100 before the running state, that is, the state of the power display unit 300 is not updated in real time. When the motor 100 is just running, the large current discharge of the battery unit 600 causes the voltage of the battery unit 600 to drop sharply, but at this time, the power of the battery unit does not decrease greatly. Therefore, when the voltage parameter is selected according to the state parameter of the battery When controlling the state of the power display module, the power information displayed by the power display unit 300 will drop sharply. Contrary to the above, not updating in real time means not changing with time, that is, keeping the state of the power display module unchanged. For example, the last state before running is that 3 indicator lights are on, and when it goes to running, 3 indicator lights are kept on. Therefore, the present application can effectively avoid situations such as sudden drop or jumping of lights or jumping lights back and forth in the power display unit 300 when the motor 100 is in use, and it can also avoid that the voltage detected by the battery unit 600 is not true at this stage. Reflecting the power of the battery unit 600, the user experience of using the electric stapler is effectively improved, so that the doctor can obtain a more realistic power of the battery unit 600 through the power display unit 300.

As feasible, as shown in FIG. 1 , the motor state detection unit 400 may include a current detection unit 4001. The current detection unit 4001 is used to detect the current of the motor 100. When the current of the motor 100 is greater than the first preset value, the first preset value is The set value is the current of the motor 100 when the motor 100 stops running, and it is determined that the motor 100 is running; otherwise, it indicates that the motor stops running. As feasible, the motor state detection unit 400 may include a voltage detection unit 4002. The voltage detection unit 4002 is used to detect the voltage difference between the positive pole and the negative pole of the motor 100. When the voltage difference between the positive pole and the negative pole of the motor 100 is greater than the second When the preset value is used, the second preset value is the voltage difference between the positive electrode and the negative electrode when the motor 100 stops running, indicating that the motor 100 is running; otherwise, it means that the motor stops running. As feasible, the motor state detection unit 400 may include a motor rotation speed detection unit 4003, which is used to detect the rotation speed of the motor 100. The motor rotation speed detection unit 4003 may be a Hall sensor capable of detecting the rotation speed of the motor 100. When the rotation speed of the motor 100 is greater than the third preset value, the third preset value is the rotation speed when the motor 100 is not running, indicating that the motor 100 is running; otherwise, it means that the motor is stopped. Before installing the battery unit for the first time until the user operates the stapler to perform actions, the motor stops running if it does not run; when the motor is running, the motor stops running if the motor does not run.

As feasible, the key detection unit 700 can be used to determine whether the motor 100 is running. The button is used to send the motor control signal to the control unit to control the motor. The motor control signal can include the motor start signal and the motor stop signal. The button detection unit 700 is used to detect the button state of the button. The button may include one of the firing button, the jaw closing button, the retract button, and the jaw opening. When the button state of the button represents the running signal, that is, the motor control given by the button The signal is the motor start signal. When it is determined that the motor control signal given by the button is the motor stop signal, and the preset time is reached, the control unit 500 can update the state of the power display unit 300 in real time. The state of the power display unit 300 is updated in real time; within a preset time, the control unit 500 controls the state of the power display unit 300 to maintain the last state of the motor before the running state, that is, the state of the power display unit 300 is not updated in real time. The preset time is the voltage recovery time of the battery cell. For example, the button detection unit 700 is used to detect the button states of the firing button and the jaw closing button of the electric stapler. The control unit 500 is configured to receive the button states of the firing button and the jaw closing button and determine whether the motor 100 is running according to the button status. When it is determined that the button status of the firing button or the jaw closing button represents the running signal, it is determined that the motor 100 is running. . The electric stapler cuts and sutures the tissue during the firing process, and during the closing process of the jaws, since the jaws need to compress the tissue, therefore, during the above two operations, the motor 100 runs under a large load and consumes electricity big. Therefore, when it is detected that the firing button of the electric stapler or the button state of the jaw closing button represents the operation signal, the battery unit 600 displayed by the battery level display unit 300 remains in the same state as before, which can avoid the above two processes. causes the power level of the battery unit 600 displayed by the power level display unit 300 to jump and jump to the position where the power level of the battery unit 600 is too low. The keys are triggered by the user to provide a running signal representing the start of the motor and a stop signal representing the stop of the motor. The key state may specifically include that the key is pressed and released. When the user manipulates the key, the change of the key state will give a running signal or a stop running signal. For example, when the user presses the button for the first time, the button changes from a low level to a high level, and a running signal is given at this time; when the user releases the button, the button changes from a high level to a low level, and the given Stop running signal. For another example, when the user presses the button for the first time, the button changes from low level to high level for the first time, and a running signal is given at this time. During this process, if it is not released, the motor will not stop; , the user presses the button again, the button changes from low level to high level for the second time, and a stop operation signal is given at this time. The above characterization can be understood to mean that the operation signal can be a variety of different types of signals, for example, a sudden change from a low level to a high level, and the stop operation signal is a sudden change from a high level to a low level. . Alternatively, the running signal can also be the odd-numbered sudden change from low level to high level, and the stop-run signal can be the even-numbered sudden change from low level to high level. Of course, the running signal can also be changed to Swap the signal type with the stop signal, etc.

In order to more accurately determine whether the motor 100 is running, in a preferred embodiment, the key detection unit 700 is further configured to detect the key states of the retract key and the jaw opening key of the electric stapler. The control unit 500 is used to receive the button states of the firing button, the jaw closing button, the retract button and the jaw opening button, and determine whether the motor 100 is running according to the button status. Or when the key state of the jaw opening key represents a running signal, it indicates that the motor 100 is running. When none of the firing button, the jaw closing button, the retracting button and the jaw opening button sends out a signal representing the operation, it means that the motor 100 is stopped.

Optionally, when it is determined that the motor 100 is running, since the control unit 500 does not update the state of the power display unit 300 in real time, the battery state detection unit 200 may stop real-time detection of the state parameters of the battery unit 600 . The power and burden of the battery state detection unit 200 can be reduced in the above manner. At the same time, since the motor 100 is in a running state and the battery unit 600 is in a discharging state, the state parameters of the battery unit 600 detected by the battery state detection unit 200 cannot accurately reflect the power of the battery unit 600 .

When it is judged that the motor 100 has changed from running to stopped running, and has stopped running for a preset time, the control unit 500 updates the state of the power display unit 300 in real time, and the preset time is the voltage recovery time of the battery unit 600, for example, according to the battery The real-time state parameter of the unit 600 updates the state of the power display unit 300 in real time. Within a preset time, the control unit 500 does not update the state of the power display unit 300 in real time, and the state of the power display unit 300 remains the last state of the motor 100 before the running state.

When the motor 100 just stops, it takes a certain time for the voltage of the battery unit 600 to recover to the voltage that can reflect the real power. Therefore, if the battery state detection unit 200 immediately detects the state parameters of the battery unit 600, the detected The state parameters of the battery unit 600 cannot accurately reflect the real power of the battery unit 600 , so when the motor 100 needs to stop running for a preset time, the control unit 500 will then perform a state of the power display unit 300 according to the real-time state parameters of the battery unit 600 . It is updated in real time, and the state of the power display unit 300 is continuously updated in real time as the shutdown state continues after a preset time. Through the above method, after the motor 100 stops running and reaches the preset time, the electric quantity of the battery unit 600 displayed by the electric quantity display unit 300 is more accurate, and can better reflect the real electric quantity of the battery unit 600 , which can prevent the electric quantity display unit 300 from displaying the electric quantity of the battery unit 600 . The problem of a sudden increase in power, for example, the indicator light of the power level jumps back and forth. For example, if 3 indicators light green, it will jump to 5 indicators light green.

The motor changes from running to stopped running, and the stopped running state lasts for a total duration. When the total duration exceeds the preset time, the total duration is divided into the duration of the previous preset time - the first period, and the preset time. Duration - the second period, after the above-mentioned stop operation reaches the preset time, it refers to the period during which the operation continues to stop after the preset time - that is, the second period. If the motor changes from running to stopped running, and then immediately turns to running after stopping, and the duration of the motor stop running is very short and less than the preset time, that is, the above total time is less than the preset time, then the motor is running from running. During the period of time when it is turned to stop running and then turn to running, the real-time update of the state of the power display unit will not occur, that is, a display state is always maintained, for example, three lights are always on.

In another embodiment, the key detection unit 700 is configured to detect the key state of the key capable of controlling the motor, and the control unit 500 is configured to receive the key state of the key capable of controlling the motor to detect the motor control given by the key capable of controlling the motor Signal. For example, a key capable of controlling a motor may include a firing key, and when the key state of the firing key represents a running signal, it is determined that the motor control signal given by the key is a motor starting signal. For another example, the button capable of controlling the motor may include a jaw closing button. When the button state of the jaw closing button represents a running signal, it is determined that the motor control signal given by the button is a motor start signal. For another example, the button capable of controlling the motor includes a tool retract button, and when the button state of the tool retract button represents a running signal, it is determined that the motor control signal given by the button is a motor start signal. For another example, the button capable of controlling the motor includes a jaw opening button. When the button state of the jaw opening button represents a running signal, it is determined that the motor control signal given by the button is a motor start signal. When none of the firing button, the jaw closing button, the retracting button and the jaw opening button sends out a signal representing the operation, it means that the motor 100 is stopped.

FIG. 3 is a flow chart of the method for displaying the power of the electric stapler in the embodiment of the present invention. As shown in FIG. 3 , the method for displaying the power of the electric stapler may include the following steps:

S101: Determine whether the motor is running.

In this step, the working current of the motor 100 may be detected to determine whether the motor 100 is running. When the working current is greater than the first preset value, it is determined that the motor 100 is working; otherwise, it is determined that the motor 100 is stopped, and the first preset value is the current of the motor 100 when the motor 100 stops running. For another example, the voltage difference between the positive pole and the negative pole of the motor 100 may be detected to determine whether the motor 100 is running. When the voltage difference between the positive pole and the negative pole of the motor 100 is greater than the second preset value, it is determined that the motor 100 is in operation, otherwise it is determined that the motor 100 is stopped, and the second preset value is that the motor 100 stops running. Voltage difference. For another example, the rotational speed of the motor 100 may be detected to determine whether the motor 100 is running. When the rotation speed of the motor 100 is greater than the third preset value, the third preset value is the rotation speed when the motor 100 stops running, indicating that the motor 100 is running; otherwise, it is determined that the motor 100 is stopped. For another example, the key states of the firing button and the jaw closing button of the electric stapler can also be detected to determine whether the motor 100 is running. When the button state of the firing button or the jaw closing button represents the running signal, it is determined that the motor 100 is running; otherwise, it is determined that the motor 100 is stopped. Further, the key states of the firing button, the jaw closing button, the retracting button or the jaw opening button of the electric stapler can be detected to determine whether the motor 100 is running. When the state of the firing button jaw closing button, the knife retracting button or the jaw opening button represents a running signal, it is determined that the motor 100 is running, otherwise it is determined that the motor 100 is stopped. Of course, other methods may also be used to determine whether the motor 100 is running, which is not limited herein.

As feasible, step S101 may be replaced by: detecting a motor control signal given by a key capable of controlling the motor.

S102: If the electric motor 100 is running, the state of the electric power display unit 300 remains the last state of the electric motor 100 before the running state, that is, the state of the electric power display unit 300 is not updated in real time.

As feasible, step S102 can be replaced with: if the motor control signal sent by the button is the motor start signal, the state of the electric power display unit remains the last state of the motor before the running state, that is, the state of the electric power display unit is not performed in real time. renew.

S103 : Optionally, if the motor 100 is running, the battery state detection unit 200 may stop the real-time detection of the state parameters of the battery unit 600 .

S104 : When it is determined that the motor 100 has changed from running to stopped running and reaches a preset time, the state of the power display unit 300 is updated in real time, and the preset time is the voltage recovery time of the battery unit 600 . A real-time update in such a situation can indicate the real-time power level of the battery cell 600 .

Real-time means changing with time, and the real-time state parameter of the battery unit is the state parameter that changes with time. From this, real-time power parameters can be obtained according to the real-time state parameters, and the real-time state parameters can be used to control the real-time update of the power display unit. Similarly, That is, the real-time power parameters can be used to control the real-time update of the power display unit. In this step, judging that the motor 100 has changed from running to stopped running can be realized by the motor state detection unit 400 or the key detection unit 700 . Judging that the motor 100 has changed from running to stop running can also be replaced by detecting whether the jaw opening button of the electric stapler is pressed or is in the process of retracting the knife, when it is detected that the jaw opening button of the electric stapler is pressed or in During the retraction process, and when the preset time is reached, the state of the power display unit 300 is updated in real time according to the real-time state of the battery unit 600 or the real-time power parameter, and the power display unit 300 indicates the real-time power of the battery unit 600. The process of opening the jaws and pushing the knife is the process of loosening the tissue. During the above two operation processes, the load of the motor 100 during operation is small and the power consumption is small. Therefore, the battery unit displayed by the power display unit 300 will not appear. The power level of 600 jumps and jumps to the position where the power level of the battery unit 600 is too low. Therefore, the state of the power level display unit 300 can be updated in real time directly according to the real-time power level of the battery unit 600. At this time, the power level display unit 300 The displayed updated power of the battery unit 600 is accurate and can truly reflect the power of the battery unit 600 .

As feasible, part of step S104 can be replaced with: when it is judged that the motor control signal given by the button is a motor stop signal, and after reaching a preset time, the state of the power display unit is updated in real time.

S105 : When it is determined that the motor 100 has changed from running to running and has stopped running for a preset time, the battery state detection unit 200 needs to perform real-time detection on the state parameters of the battery unit 600 again.

In this step, if S103 is previously performed, this step is performed when it is determined that the motor 100 has changed from running to stopped running, and the stopped running has reached the preset time. Of course, it can also be determined that the jaw opening button of the electric stapler is pressed or is in the process of retracting, and after the preset time is reached, the battery state detection unit 200 needs to perform real-time detection of the state parameters of the battery unit 600 .
