Referring to fig. 1, fig. 1 is a schematic diagram of a harmonic knife system 1. The harmonic blade system 1 includes a harmonic blade device 10 and a charging stand 20. The harmonic blade device 10 includes a converter 12, a power module 14, and a harmonic blade 16. The converter 12 is used for converting energy, such as converting electrical energy provided by the power module 14 into mechanical energy (e.g. vibration) provided to the cutting head for performing operations such as cutting or hemostasis. Preferably, the transducer 12 includes a transducer element for energy conversion, and the material of the transducer element may be a piezoelectric material such as, but not limited to, lead zirconium titanate (PZT). The transducer 12 may be used in combination with the harmonic blade body 16 in an insert or module that may facilitate replacement or sterilization operations. The converter 12 is preferably reusable, but if problems such as over-age, reduced conversion efficiency, or damage from external impacts are encountered, replacement is required to maintain the performance of the harmonic knife device 10.
The power module 14 may include, for example, a battery or a battery pack and a power management system (BMS). The battery is not limited to, for example, a rechargeable battery such as a lithium battery. The present invention is not limited to the number of the batteries, and for example, a plurality of batteries may be connected in parallel or in series and then packaged into a battery pack according to the usage requirement. The power management system can control the charging and discharging states of the power module, for example, through a Microprocessor (MCU), so as to avoid the situation of battery damage caused by overcharge or overdischarge. The power module 14 may be used in combination with the harmonic blade body 16 in an insert or module fashion and is preferably reusable. However, if problems such as an increase in service life, a decrease in charge/discharge efficiency, or damage due to external force or sterilization are encountered, replacement is required to maintain the stability of power supply.
The harmonic blade 16 may include, for example, a body structure 161 and a blade structure 162. The body structure 161 is used for integrating the converter 12 and the power module 14 and may have control structures such as a power switch 1611 and a tool bit handle 1612. The blade structure 162 has an extension 1621 and a cutting head 1622. The extension 1621 may extend the distance of the cutting head 1622 from the body structure 161 such that the harmonic knife device 10 may facilitate operations such as, but not limited to, minimally invasive surgery. When the user presses the power switch 1611, the power module 14 provides power to the converter 12, and the converter 12 receives the power to generate high-frequency (for example, but not limited to, 55k Hz to 56k Hz) oscillation, which is transmitted to the cutter head 1622 through the extension 1621. The user can also control the opening and closing of the tool bit 1622 through the tool bit handle 1612 to clamp the object. The blade structure 162 may be detachably combined with the body structure 161, and the blade structure 162 is preferably disposable, so as to avoid the problem of infection of the patient caused by incomplete sterilization or disinfection.
The charging base 20 and the harmonic knife device 10 can be separately arranged, and the charging base 20 has a plurality of slots 201 for the power module 14 to be inserted and charged. It should be noted that the harmonic knife system 1 shown in fig. 1 is only for explaining the relationship and the approximate function between each component, and is not intended to limit the present invention.
Referring to fig. 2, fig. 2 illustrates a first embodiment of the present invention. The power module 14 has a battery 141 and a first control element 142. The first control element 142 is, for example but not limited to, a microprocessor or a field programmable logic gate array (FPGA). The first control element 142 stores the battery information BI, for example, by an external memory or register (not shown in fig. 2) or a memory element inside the first control element 142. The battery information BI is, for example, but not limited to, the accumulated charging or discharging time (the number of service hours) of the power module 14, the charging efficiency (such as the voltage or current rise curve during charging), or the number of charging and discharging times. It should be noted that the battery information BI is only an example and not intended to limit the present invention, and the battery information BI may also be information related to the safety of the power module 14, for example, temperature records during charging and discharging of the power module 14 or the number of times the power module 14 performs sterilization. When the power module 14 needs to be charged, the power module 14 is inserted into the charging dock 20 for charging.
The cradle 20 has a second control element 202. The second control element 202 is, for example, but not limited to, a microprocessor or an FPGA. When the power module 14 is inserted into the charging stand 20, the second control element 202 reads the battery information BI. Wherein, when the battery information BI exceeds the first threshold, the charging dock 20 enters the alert state. It should be noted that the unit of the first threshold is a numerical value corresponding to the battery information, for example, when the battery information BI is the usage time, the unit of the first threshold is time. In addition, the warning state may be a state display or a composite state, such as a warning of sound and light simultaneously, which is used to inform the user of the state display or the composite state. Preferably, the charging dock 20 entering the warning state may also stop supplying power, for example, when the battery information BI exceeds the first threshold, the charging dock 20 stops charging the power module 14. It should be noted that the charging base 20 may have a plurality of slots 201 for charging a plurality of power modules 14, and the charging base 20 may determine whether to charge the power modules 14 according to the battery information BI transmitted by each power module 14. With the first embodiment, the reliability of the power module 14 can be managed by the battery information BI transmitted by the power module 14.
Referring to fig. 3, fig. 3 illustrates a second embodiment of the present invention. The converter 12 comprises a third control element 122 (e.g. a microprocessor or FPGA) and a conversion unit 121, the third control element 122 providing status information SI. Specifically, the status information SI is, for example, but not limited to, the usage time of the transducer 12 or the piezoelectric conversion efficiency. Preferably, the status information SI may include an identification signal such as, but not limited to, a cargo number, a lot number or an identification ID of the transducer. The power module 14 has a first control component 142, and the first control component 142 stores the status information SI. The cradle 20 has a second control element 202. Wherein, when the power module 14 is inserted into the charging stand 20, the second control element 202 reads the status information SI. When the status information SI exceeds the second threshold, the charging dock 20 enters the alert status. It should be noted that the unit of the second threshold is a numerical value corresponding to the status information. Specifically, when the power module 14 is inserted into the charging stand 20, the charging stand 20 can determine the state of the converter 12 installed on the harmonic blade 16 according to the state information SI stored in the power module 14, such as whether the converter is still in use or whether the conversion efficiency is insufficient. Thus, the user can be assisted to make the determination of replacement or continuous use by the alert state entered by the charging stand 20.
Referring to fig. 4, the battery module 14 may further include a dc-dc converter 143. The converter 12 may further comprise an oscillator element OSC, a push-pull dc-ac amplifier 123, a Filter, a voltage amplifier VOP and a current amplifier IOP. The dc-dc converter 143 is coupled to the push-pull dc-ac amplifier 123 of the converter 12 and provides a boosted or a reduced dc power to the push-pull dc-ac amplifier 123. The push-pull type dc-ac amplifier 123 converts the dc power into the ac power according to the ac signal provided by the third control element 122, and provides the ac power to the conversion unit 121. Preferably, the conversion unit 121 and the push-pull type dc-ac amplifier 123 may be provided with a Filter to improve the signal quality. The voltage amplifier VOP and the current amplifier IOP can provide the feedback signal of the third control element 122 for the purpose of monitoring the efficiency of the converter 12, for example.
Referring to fig. 5, fig. 5 illustrates a third embodiment of the present invention. The cradle 20 also includes a read interface 204. The read interface 204 is a wireless transmission interface such as Universal Serial Bus (USB) or Bluetooth. The reading interface 204 provides the electronic device 30 to read the battery information BI or the status information SI. It should be noted that the present invention is not limited to the setting position of the reading interface 204, and the reading interface 204 may be set at any position on the charging dock 20, or may be set inside the charging dock 20, and is connected to the electronic device 30 through wireless transmission. The electronic device 30 is a computer or a mobile device. The user can perform, for example, consumable management of the harmonic knife device 10 by reading the battery information BI or the status information SI. Specifically, the second control component 202 of the charging dock 20 can store at least one set of battery information BI or status information SI. When reading one or more sets of battery information BI or status information SI via the electronic equipment 30, the user can determine whether to replace or order the consumables such as the converter 12 or the power module 14. However, the above description is only exemplary and not intended to limit the present invention, and any application performed by the electronic device 30 to read the battery information BI or the status information SI is within the scope of the present embodiment.
In a fourth embodiment of the present invention, a harmonic knife device includes a converter, a power module and an alarm device. The converter comprises a conversion unit for performing energy conversion and a third control element coupled to the conversion unit for monitoring state information of the conversion unit.
