Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Fig. 1 to 3 are schematic structural diagrams of a consumable control system of a multi-key ultrasonic scalpel according to the present invention. As is well known, ultrasonic scalpels typically include a blade assembly having a blade shaft therein. The cutter bar or the whole cutter is a consumable material, namely the cutter bar or the whole cutter needs to be scrapped after being used for a period of time, so that the parameters such as the using times, the remaining times and the like of the cutter bar need to be monitored in real time. The consumable control system of the multi-key ultrasonic scalpel comprises an electrical isolation module 10, a main control module 20 electrically connected to the input side of the electrical isolation module 10, an auxiliary control module 30 electrically connected to the output side of the electrical isolation module 10, a control signal input module 40 electrically connected to the auxiliary signal control module 30, and a consumable control module 50 electrically connected to the control signal input module 40. It is contemplated that the consumable control system of the multi-button ultrasonic scalpel may also be used to control the operation of the ultrasonic scalpel, such as to start, perform surgical procedures, and the like. The consumable control system of the multi-key ultrasonic scalpel further comprises other electronic components or functional units, such as a buffer, a voltage stabilizing circuit unit, a power supply unit and the like, which are well known to those skilled in the art and will not be described in detail herein.

The electrical isolation module 10 is used to electrically isolate the signal input end from the signal output end, that is, to provide electrical isolation for the primary and

secondary control modules

20 and 30, but is prior art and will not be described herein again. The galvanic isolation module 10 has an input side and an output side, the input side being connected to the main control module 20 for receiving control commands from the main control module 20. As is known, any ultrasonic scalpel system is connected to a controller which outputs ultrasonic energy in various parameters to drive the ultrasonic scalpel system to operate in accordance with the surgeon's instructions. The output side of the electrical isolation module 10 is electrically connected to the secondary control module 30, and the output signal enables the secondary control module 30 to start normal operation. Meanwhile, it is well known that the input side and the output side of the electrical isolation module 10 have an output end and an input end, and it is understood that in an actual product, the output end and the input end are metal pins.

The main control module 20 may be a microprocessor, and is configured to monitor whether consumables are accessed, and control the ultrasonic scalpel to start to work and perform a surgical operation according to the control signal output by the control signal input module 40 after the consumables are accessed. Specifically, main control module 20 reads the analog signal value that auxiliary control module end 30 gathered through the communication, and this analog signal can be the button end input value of consumptive material system end, and this analog signal is used for judging whether the button is pressed, and then control scalpel operating condition, main control module 20 reads the storage information that is located consumptive material system such as cutter unit in the middle of that auxiliary control module end 30 read through the communication simultaneously, judges whether this consumptive material system is in effective life-span. Of course, it is conceivable that the main control module 20 may also output or process other control signals, and the working principle and the control method thereof are per se the prior art and are not described herein again.

The secondary control module 30 may also be a microprocessor, and it may share the microprocessor with the consumable control module 50, i.e., the microprocessor may perform different tasks. The sub-control module 30 may perform information interaction with the main control module 20 through the communication interface to control respective control information. The communication interface can be any mode of communication interface. The connection between the consumable and the system is 2 wires, and the 2-wire interface is electrically connected with the module 40, so that a two-wire interface is formed. The two-wire interface can be compatible with analog signals and digital signals, namely, the analog signals and the digital signals are multiplexed in the two-wire interface in a time division mode. The sub-control module 30 mainly works for the control signal input module 40 and the consumable control module 50 to acquire ADC analog data identification keys, and to operate the memory unit, i.e., the read/write, transmit/receive information of the IC, and the like.

The control signal input module 40 includes a key input unit 41 electrically connected to the sub signal control module 30, and a detection resistor 42 connected in series with the key input unit 41. The KEY input unit 41 is connected in series to the secondary control module 30 through two wires, and specifically, the two wires of the KEY input unit 40 are electrically connected to a KEY + pin and a KEY-pin of the microprocessor, respectively. The key input unit 41 includes at least two key subunits 411 connected in parallel, and at least two voltage dividing resistors 412 electrically connected to each key subunit 411. Any two of the key subunits 411 are arranged in parallel so that the key input unit 40 has only two control wires. The key subunit 411 may be a switch. In the present embodiment, the key input unit 41 includes n key subunits 411, such as 5. The switch itself should be of the prior art, such as a key switch, etc., and will not be described herein. The voltage dividing resistor 412 is used to identify which switch is turned on. When one of the switches is turned on, the voltage division value between each of the voltage division resistors 412 and the detection resistor 42 is different, so that it is possible to identify which switch is turned on. The detection resistor 42 is conventional in the art and will not be described in detail herein. As can be seen from the actual circuit diagrams of fig. 2 and 3, the detection resistor 42 is disposed in the generator, and the key input units 41 are disposed in the ultrasonic blade, and which key input unit 41 is turned on and pressed can be detected by the detection resistor 42.

The consumable control module 50 includes a consumable database 51, a data storage unit 52 electrically connected to the key input unit 40, a data reading unit 53, a life judging unit 54, a consumable on-line identifying unit 55, a delay judging module 56, and a control signal output unit 57. It is conceivable that the consumable control module 50 further includes other functional units according to actual needs, such as a consumable self-test unit, a standby functional unit, etc., which are functions commonly found in the prior art and will not be described in detail herein. The consumable database 51 is used to record information of each consumable, such as the model and number of the consumable, the remaining life of the consumable corresponding to each number, and so on. The data storage unit 52 may be an IC memory chip, which is connected in parallel to the circuit of the key subunit 411, and is used to obtain which key switch is pressed, record the number of times that the key is pressed, and update information of consumables with corresponding numbers, such as updating the remaining life of the consumables. As shown in the actual circuit diagrams of fig. 2 and 3, the data storage unit 52, i.e., an IC memory chip, is fixedly disposed in the ultrasonic scalpel. The data reading unit 53 is configured to read information, such as a serial number, of consumables, such as a blade bar, which are provided for the ultrasonic scalpel. The life judging unit 54 is for judging the life of the assembled consumable, i.e., the remaining number of times. If the remaining number of times is equal to 0, an alarm signal is output from the control signal output unit 57 while a control signal is output for the sub-control module 30. When the sub-control module 30 receives the control signal, it stops outputting the control signal to the main control module 30, and the ultrasonic scalpel does not output any signal even if one of the key subunits 411 is pressed. The consumable on-line recognition unit 55 is used to recognize whether a consumable is assembled and whether the assembled consumable meets the requirements, such as being adapted to the consumable control system. The invalid supplies can be prevented from being accessed by the supplies on-line recognition unit 55. Of course, if the consumable control system is always in the on state, the consumable on-line identification unit 55 will be executed in a loop until there is a valid consumable connected. The delay judging module 56 is used for filtering interference and preventing misjudgment, that is, judging the time of the inserted consumable item, if the insertion time of the consumable item is too short, the delay judging module 56 will not output a control signal, so as to avoid the interference of the wrong insertion to the whole control system and prevent misjudgment. The control signal output unit 57 is configured to receive control signals from the respective functional units, transmit the control signals to the sub-control module 30, and transmit the control signals to the main control signal and peripherals such as a display device through the sub-control module 30.

For the real object diagram provided in fig. 2, after a consumable is assembled into the ultrasonic scalpel, the consumable control module 50 identifies and detects the consumable, and if the consumable is matched with the ultrasonic scalpel and the remaining number of times of use is not zero, it indicates that the ultrasonic scalpel can be used. When the delay time meets the requirement, any one of the KEY switches in the KEY subunit 411 is pressed, the IO1 of the secondary control module 30 pulls up the KEY + terminal, and when the IO2 pulls down the KEY-terminal, the KEY-and KEY + terminals form an effective loop, and an Analog2 interface is used as an ADC Analog signal interface to read the divided voltage value between the Rn and R379 terminals. Or when KEY + is pulled down from IO1 and KEY-is pulled down, KEY + and KEY-form an effective loop, and an Analog1 interface, which is used as an ADC Analog signal interface, reads a voltage division value between R382 and Rn, so that the ultrasonic scalpel can start to be started and used under the control of the main control module 20. Meanwhile, the auxiliary control module 30 sets the KEY-end to be in an output mode and pulls the KEY-signal low, the data storage unit 52, i.e., the IC chip, forms a loop and can enter a working mode, and the auxiliary control module 30 can perform read-write operation on the IC, so as to ensure the correct use of the consumable item.

It is conceivable that, for some cases, the IC chip may not be provided, and the consumable control system provided by the present invention may also control the conventional 2-wire cutter. The 2-wire cutter comprises two key subunits which are arranged in parallel, the two key subunits are respectively connected with one diode, and the connection polarities of the two diodes are opposite. The consumable control system provided by the invention can also control the consumable control system to work normally, namely, the consumable control system is compatible with the traditional ultrasonic scalpel system.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
