[0046]

[0047] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0052] It should be noted that, at present, ultrasonic surgical equipment is generally composed of a host, a transducer and different blade heads. The blade head is installed on the transducer. The transducer is connected to the host to receive electrical energy and convert it into mechanical energy for use by the blade head.

[0053] Existing ultrasonic surgical equipment may experience various abnormal conditions when working. For example, during the ultrasonic bone knife cutting process, the tool may get stuck and unable to reciprocate due to excessive force used by the user, or the host output may fail. In these cases, the user will be confused about the current working status, and the working status can generally only be indicated on the host. When the user holds the transducer for operation, he needs to look up and observe the indication content on the host to obtain the current working status of the transducer, which leads to a poor user experience.

[0054] At the same time, when using ultrasonic surgical equipment, users generally operate under a microscope, and ultrasonic bone knives or ultrasonic cutting hemostatic knives, for example, will produce corresponding smoke during operation to block the user's line of sight. When the user does not understand the current working status, he also needs to look up and observe the instructions on the host to obtain the current working status of the transducer, resulting in a poor user experience.

[0055] In order to solve the above-mentioned defects, the present embodiment can provide a transducer with a visualized working status, and the status indication circuit 3 can be set on the shell 1 of the transducer. The working status signal generated by the host is converted into a display signal through the status receiving circuit 2 and then transmitted to the status indication circuit 3, and then the current working status is displayed through the status indication circuit 3. Compared with the existing system that requires the user to look up and observe the host indication to obtain the current working status, the present embodiment can indicate the current working status on the transducer. When the user holds the transducer for operation, it can be directly obtained through the indication on the transducer, thereby improving the user experience.

[0056] For ease of understanding, the following combination Figures 1 to 5 The transducer with visualized working status provided in the embodiment of the present application is introduced in detail.

[0057] Reference Figure 1 , Figure 1This is a structural block diagram of the first embodiment of the transducer with visualized working status proposed in the embodiment of the utility model.

[0058] like Figure 1 As shown, in this embodiment, the transducer is connected to the host, and the transducer includes: a shell 1, a status indication circuit 3 and a status receiving circuit 2; wherein the status indication circuit 3 is arranged on the shell 1, and the status receiving circuit 2 is respectively connected to the status indication circuit 3 and the host.

[0059] It should be noted that the above-mentioned working status visualization transducer provided in this embodiment can be used as a transducer on any ultrasonic surgical equipment, and can be connected to the host in the ultrasonic surgical equipment through cable 5 to transmit electrical energy, and then the electrical energy is converted into mechanical energy through the transducer. Of course, it can also be used on other equipment that requires the use of a transducer. This embodiment uses the transducer in the ultrasonic surgical equipment as the above-mentioned working status visualization transducer for illustration, but does not impose any limitation on this.

[0060] It can be understood that the transducer with visualized working status provided in this embodiment (hereinafter referred to as transducer) can still be connected to the host through the cable 5 to receive electrical energy. The above-mentioned shell 1 can be the outer shell of the transducer. The status indication circuit 3 and the status receiving circuit 2 can be set on the shell 1 of the transducer. They can be fixed on the outer wall of the shell 1, and of course can also be set in the internal cavity of the shell 1. In short, they can be set in an integrated form with the transducer.

[0061] The status receiving circuit 2 can also be connected to the host through the cable 5, and a power line, a ground line and a signal transmission line can be added to the original cable 5. Since there are only two wiring harnesses between the existing transducer and the host, in order not to increase the outer diameter of the entire cable 5, the wiring harness connecting the status receiving circuit 2 and the host in this embodiment can adopt an ordinary AWG22 wiring harness. Of course, other wiring harnesses can also be used, and this embodiment is not limited to this.

[0062] The above-mentioned status receiving circuit 2 is used to convert the current working status signal of the transducer generated by the host into a corresponding display signal, and transmit the display signal to the status indication circuit 3; the above-mentioned status indication circuit 3 is used to indicate the current working status of the transducer when receiving the display signal.

[0063] It should be understood that the above-mentioned working status signal can be a signal generated by the host itself for displaying the current working status of the transducer. Since the existing host can support the display of the working status, this embodiment can directly lead the current working status signal of the transducer generated by the host to the status receiving circuit 2, saving costs.

[0064] After the status receiving circuit 2 receives the working status signal, it can convert it into a corresponding display signal and transmit it to the status indication circuit 3. The status indication circuit 3 can be composed of a number of LED lights of different colors, and different lights can represent different current working states according to the received display signal. Of course, it can also be composed of a display screen to display the current working status.

[0065] It should be emphasized that the current working state of the transducer in this embodiment is described using three states, which may include normal working state, stuck knife working state and faulty working state, among which the normal working state may represent the normal operation of the transducer, the stuck knife working state may represent that the knife head is stuck, and the faulty working state may represent that the device itself has a fault. Then, three colors of LED lights can be set to represent the above three states, respectively, which may be a green light that is always on to represent the normal working state, a yellow light that is always on to represent the faulty working state, and a flashing red light to represent the stuck knife working state. Of course, it can also be other colors and other flashing modes, which are not limited by this embodiment.

[0066] It should also be noted that the above-mentioned host in this embodiment can determine the current working state of the transducer by detecting the working current of the transducer. For example, the above-mentioned host can collect the current transmitted to the transducer. When the current is within a preset current range, it can indicate that it is currently in a normal working state. When the current is less than the preset current range, it can indicate that it is currently in a card knife working state. When the current is greater than the preset current range, it can indicate that it is in a faulty working state. The above-mentioned preset current range can be set according to actual conditions.

[0067] In the specific implementation, the host collects the current transmitted to the transducer, and compares it with the preset current range, generates a corresponding working status signal according to the comparison result, and then transmits it to the status receiving circuit 2. The status receiving circuit 2 converts the working status signal into a corresponding display signal. The status indication circuit 3 can display the corresponding current working status according to the display signal, so that the user can directly observe the indication content on the transducer to obtain the working status without looking up, thereby improving the user experience.

[0068] Furthermore, considering that the structures of different transducers may be different, and thus the positions of the state receiving circuit 2 and the state indicating circuit 3 may also be different, this embodiment adopts Figure 2 and Figure 3 Two types of transducers are described, namely conventional cooling transducer and water-cooling transducer;

[0069] The following first combines Figures 2 to 6 For a description of conventional cooling transducers, refer to Figure 2 , Figure 2 FIG. 1 is a schematic diagram of the structure of an embodiment of the utility model applied to a conventional cooling transducer. Figure 2 As shown, a cable 5 is provided at one end of the shell 1, which is connected to the host through the cable 5. The status indication circuit 3 and the status receiving circuit 2 can be arranged in the internal cavity of the shell 1 (not shown in the figure), and a first observation window 4 is opened at one end of the shell 1 close to the cable 5, and the on and off status of the LED light can be observed through the first observation window 4.

[0070] In order not to affect the overall design of the transducer and avoid affecting the stability of the LED lamp installation due to the movement of the transducer, refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the circuit board 6 in the first embodiment of the transducer with visualized working status proposed in the embodiment of the utility model, as shown in FIG. Figure 3 As shown, the status indication circuit 3 and the status receiving circuit 2 can be integrated on a circuit board 6, a card slot (not shown in the figure) is provided inside the shell 1, the circuit board 6 is fixed inside the shell 1 through the card slot, and a first observation window 4 for observing the status indication circuit 3 is opened on the shell 1.

[0071] It should be noted that if Figure 3 As shown, since the longitudinal cross-section of the transducer is circular, the circuit board 6 can be set to be circular, and the status indication circuit 3 and the status receiving circuit 2 are integrated on the circuit board 6, and the status indication circuit 3 can be connected to the cable 5 through the wiring port H1 to receive the working status signal;

[0072] The circuit board 6 can be fixed to one end of the transducer close to the cable 5, and the LED light in the status indication circuit 3 is aligned with the first observation window 4, and then the circuit board 6 outside and inside the housing 1 is insulated by an acrylic plate, which is convenient for users to observe. Since the circuit board 6 is set at the tail of the transducer, the main change area involved is the adapter board of the transducer, that is, the back cover of the transducer, and since the LED light is used, the power consumption is low, so two signal transmission lines, a power line and a ground line can be added to the original cable 5, which will not affect the thickness change of the entire cable 5. At the same time, under the condition that the appearance of the housing 1 remains unchanged, observation can be achieved by only opening a first observation window 4, and the structure is simple.

[0073] Furthermore, in order to facilitate the connection between the circuit board 6 and the cable 5, a wiring port H1 is also provided on the circuit board 6 in this embodiment, and two signal transmission lines, a power line and a ground line are connected to the status receiving circuit 2 through the wiring port H1. The specific model of the wiring port H1 is not limited in this embodiment.

[0074] Continue to refer to Figure 3 In this embodiment, the middle part of the circuit board 6 is hollowed out, that is, a through hole is opened in the middle, which can meet the design of the inner conduit of the transducer with water cooling and can be applied to the water-cooled transducer.

[0075] Further, in order to convert the working state signal into a display signal, continue as follows Figure 1 As shown, in this embodiment, the state receiving circuit 2 includes: a signal conversion module 21 and a driving module 22; wherein the signal conversion module 21 is connected to the host and the driving module 22 respectively, and the driving module 22 is also connected to the state indicating circuit 3;

[0076] The signal conversion module 21 is used to convert the current working status signal of the transducer generated by the host into a corresponding driving signal, and transmit the driving signal to the driving module 22; the driving module 22 is used to convert the driving signal into a corresponding display signal, and transmit the display signal to the status indication circuit 3.

[0077] It should be noted that the signal conversion module 21 in this embodiment may include a microcontroller unit (MCU) chip, the signal input pin of the MCU chip is connected to the host, and the normal state output pin ( Figure 1 RUN), card knife status output pin ( Figure 1 STUCK) and fault status output pin ( Figure 1 ERROR) are connected to the drive module 22;

[0078] The MCU chip is used to convert the working state signal into any one of a normal state driving signal, a card knife state driving signal or a fault state driving signal, and transmit the driving signal to the driving module 22.

[0079] Furthermore, the above-mentioned MCU chip can receive the working status signal through the signal input pin, and convert it internally into one of the normal state drive signal, the knife state drive signal or the fault state drive signal, and then transmit it to the drive module 22, wherein the normal state drive signal corresponds to the normal working state, the knife state drive signal corresponds to the knife state, and the fault state drive signal corresponds to the fault state.

[0080] The driving module 22 may include first to third driving units; wherein the first driving unit is respectively connected to the normal state output pin of the MCU chip and the state indication circuit 3, the second driving unit is respectively connected to the card knife state output pin of the MCU chip and the state indication circuit 3, and the third driving unit is respectively connected to the fault state output pin of the MCU chip and the state indication circuit 3;

[0081] The first driving unit is used to convert the normal state driving signal into a first display signal, and transmit the first display signal to the state indication circuit 3; the second driving unit is used to convert the knife state driving signal into a second display signal, and transmit the second display signal to the state indication circuit 3; the third driving unit is used to convert the fault state driving signal into a third display signal, and transmit the third display signal to the state indication circuit 3.

[0082] When the status indication circuit 3 receives the first display signal, the green light is always on; when the second display signal is received, the yellow light is always on; when the third display signal is received, the red light flashes.

[0083] In a specific implementation, the status receiving circuit 2 and the status indicating circuit 3 are integrated on a circuit board 6 and then arranged inside the housing 1, and a working status signal is received through the wiring port H1, transmitted to the status receiving circuit 2, and then the signal is converted, and finally the corresponding working status is displayed according to the conversion. The above method can achieve observation by only opening a first observation window 4 without changing the appearance, and the structure is simple. At the same time, the user does not need to look up to observe the host display, thereby improving the user experience.

[0084] Further, refer to Figure 4 , Figure 4 The circuit schematic diagram of the wiring port H1 of the first embodiment of the transducer with visualized working status proposed in the embodiment of the utility model is as follows: Figure 4 As shown, this embodiment uses a connection port H1 of model PZ254V-11-04P for illustration, and the first pin of the connection port H1 is connected to the power line added in the cable 5 ( Figure 4 VCC), and is also connected to the status receiving circuit 2 to provide a working voltage for subsequent components. The specific voltage value is not limited in this embodiment; the second pin of the wiring port H1 is connected to the ground wire added in the cable 5 ( Figure 4 GND in the middle), and at the same time connected to the status receiving circuit 2 to provide grounding for subsequent components; the third pin and the fourth pin of the wiring port H1 are respectively connected to a signal transmission line added in the cable 5 ( Figure 4 US_RX and US_TX) and is simultaneously connected to the status receiving circuit 2 to transmit the working status signal.

[0085] Furthermore, since this embodiment uses a wired method to transmit the working status signal, Figure 5 , Figure 5 The circuit schematic diagram of the MCU chip in the first embodiment of the transducer with visualized working status proposed in the embodiment of the utility model is as follows: Figure 5 As shown, the model of the MCU chip used in this embodiment is: STM8L001J3M3 ( Figure 5 The signal conversion module 21 further includes: a first capacitor C1 and a second capacitor C2;

[0086] Among them, the first pin and the eighth pin of the MCU chip U1 are connected to the host, the third pin of the MCU chip U1 is grounded, the third pin of the MCU chip U1 is also connected to the second end of the first capacitor C1 and the second end of the second capacitor C2 respectively, the first end of the first capacitor C1 is respectively connected to the power supply, the first end of the second capacitor C2 and the fourth pin of the MCU chip U1, the fifth pin of the MCU chip U1 is connected to the first drive unit, the sixth pin of the MCU chip U1 is connected to the second drive unit, and the seventh pin of the MCU chip U1 is connected to the third drive unit.

[0087] It should be noted that the first pin of the MCU chip U1 in this embodiment can be connected to the fourth pin of the wiring port H1, and the eighth pin of the MCU chip U1 can be connected to the third pin of the wiring port H1, so as to receive the working status signal ( Figure 5 in US_TX and US_RX).

[0088] It is understandable that the first end of the first capacitor C1 can be connected to the first pin of the wiring port H1, the third pin of the MCU chip U1 can be connected to the second pin of the wiring port H1, and the voltage of the above power supply is the working voltage received by the wiring port H1.

[0089] Meanwhile, the capacitance of the first capacitor C1 may be 10 uF, and the capacitance of the second capacitor C2 may be 100 uF. Of course, other capacitance values ​​may also be used, which is not limited in this embodiment.

[0090] It should be emphasized that the fifth pin of the MCU chip U1 is the normal state output pin ( Figure 5 The sixth pin of the MCU chip U1 is the card knife state output pin ( Figure 6 STUCK in the middle), which can be connected to the second drive unit to output the card knife state drive signal; the seventh pin of the MCU chip U1 is the fault state output pin ( Figure 5 It can be connected to the third drive unit to output a fault state drive signal.

[0091] In a specific implementation, the working state signal is received through the first pin and the eighth pin of the MCU chip U1, and converted into a corresponding state driving signal, which is output through the fifth pin, the sixth pin or the seventh pin of the MCU chip U1 respectively.

[0092] Further, refer to Figure 6 , Figure 6 The circuit schematic diagram of the driving module 22 in the first embodiment of the transducer with visualized working state proposed in the embodiment of the utility model is as follows: Figure 6 As shown, the state indicating circuit 3 includes: first to third light emitting diodes LED3; the first driving unit includes: first to third resistors R3 and a first transistor Q1;

[0093] Among them, the first end of the first resistor R1 is connected to the power supply, the second end of the first resistor R1 is connected to the anode of the first light-emitting diode LED1, the cathode of the first light-emitting diode LED1 is connected to the collector of the first transistor Q1, the emitter of the first transistor Q1 is grounded, the base of the first transistor Q1 is respectively connected to the second end of the second resistor R2 and the first end of the third resistor R3, the first end of the second resistor R2 is connected to the fifth pin of the MCU chip U1, and the second end of the third resistor R3 is connected to the emitter of the first transistor Q1.

[0094] It should be noted that the first light emitting diode LED1 may be a diode for emitting green light, the first end of the first resistor R1 may be connected to the first pin of the wiring port H1, and the first transistor Q1 may be an NPN transistor of model SL3904.

[0095] In actual use, when the fifth pin of the MCU chip U1 outputs a normal state driving signal, the collector and emitter of the first transistor Q1 are turned on, the collector of the first transistor Q1 generates a first display signal transmitted to the first light-emitting diode LED1, and the first light-emitting diode LED1 is always green.

[0096] Further, the second driving unit includes: fourth to sixth resistors R6 and a second transistor Q2;
