[Figure 4] This is a schematic diagram of the components of an ultrasound handpiece used to probe and excise patient tissue. [Figure 5] This is a flowchart illustrating the method for operating an ultrasound tool system to probe and excise patient tissue. [Figure 6] This is a graph of the waveform of the AC drive signal supplied to the ultrasound handpiece for probed patient tissue. [Figure 7] This is a waveform graph used to identify the characteristics of patient tissue being probed by an ultrasound tool system. [Modes for carrying out the invention]

[0030] Figure 1 shows an ultrasound tool system 10 for probing and excising patient tissue. The ultrasonic tool system 10 includes a control console 12 and an ultrasonic handpiece 14. This is possible. The ultrasonic handpiece 14 can include the tip 16. While the stem 10 is operating, the control console 12 exceeds the AC drive signal that causes the chip 16 to vibrate. The ultrasonic handpiece 14 can then supply the vibration tip 16 to the patient. The probe can be positioned relative to the tissue, allowing it to probe or excise the tissue it comes into contact with.

[0031] When using the ultrasound tool system 10, the operator can leave other types of patient tissue intact. However, there may be cases where it is desirable to remove several types of patient tissue. For example, the surgeon, Remove unhealthy tissue (e.g., tumor tissue) while preserving adjacent healthy tissue intact. To cause damage to adjacent patient tissues of different types (e.g., pia mater, blood vessel walls) There are times when it is desirable to remove certain patient tissues (e.g., dura mater, muscle tissue) without resorting to other methods. In particular, when the surgeon's tissue view is obstructed or when distinguishing between one type of tissue and another. If it is difficult to distinguish between them by visual inspection, differentiate between different types of patient tissue. This can be difficult. Therefore, the ultrasonic tool system 10 probes the tissue in contact. And it detects and indicates the type of tissue it is in contact with without causing tissue damage. It can be constructed in the following way.

[0032] Specifically, the control console 12 clicks in a manner insufficient to excise the contacted tissue. It may be configured to supply an AC drive signal that vibrates the p 16 to the ultrasonic handpiece 14. Furthermore, the control console 12 monitors the displacement amplitude of the chip 16 caused by vibration. The tissue is slowly changed and pushed and pulled by the vibrating tip 16. It may be configured to monitor the tissue's response at that time. In particular, vibrations are when the displacement amplitude changes. This can result in vertical vibrations that push and pull the tissue. The displacement amplitude of tip 16 increases. As you get older, harder tissues are harder to push and pull than relatively softer tissues. It can become more difficult. In other words, with harder tissue, as the displacement amplitude of tip 16 increases... This could potentially add more resistance to the ultrasound handpiece 14 than softer tissue. Therefore, the control console 12 uses ultrasonic waves in response to changes in the displacement amplitude of the tip 16. The rigidity of the contact tissue is tracked by identifying the mechanical resistance of the handpiece 14, and based on that It can be configured to identify tissue characteristics. The tissue characteristics are determined by the ultrasonic handpiece 14. The type of tissue in contact, for example, whether the tissue is healthy or unhealthy, or the species of tissue in contact. It can show types (e.g., blood vessel walls, dura mater). Next, the control console 12 controls hearing The system is designed to show organizational characteristics to the user through visual and / or tactile displays, etc. It is possible.

[0033] The above-described operation of the ultrasonic tool system 10 is performed when the ultrasonic tool system 10 is probing This can happen when the ultrasonic tool system 10 is set to operate in professional mode. In response to receiving a display of tissue characteristics while operating in working mode, the operator can click It is possible to determine whether P16 is in contact with tissue that needs to be removed. The surgeon configures the tip 16 to vibrate sufficiently to excise the contacted tissue. The control console 12 supplies an AC drive signal to the ultrasonic handpiece 14. You can activate the control mode.

[0034] In addition to the tip 16, the ultrasonic handpiece 14 includes the main body 18 and the sleeve 20. The main body 18 is a handpiece 14 that the operator can grasp and operate. The handle can be defined. The main unit 18 can be used with different interchangeable chips 16. To enable this, the chip 16 may be detachably coupled to the main body 18. This can form the proximal end of the ultrasonic handpiece 14 and is connected to the main body 18. The tip 16 can form the distal end of the ultrasonic handpiece. "Proximal" refers to the ultrasonic... For the operator holding the sonic handpiece 14, the set to which the tip 16 is applied It can be understood that it is far from the tissue, and "distal" means far from the operator, and ultrasound It can be understood that the tip 16 of endpiece 14 is located in the tissue to which it is applied.

[0035] The ultrasonic handpiece 14 is detached from the control console 12 via the electrical cable 22. It can be connected. One end of the electrical cable 22 is connected to the ultrasonic handpiece 14. The proximal end of the main unit 18 can be permanently connected, and the other end of the electrical cable 22 is connected to the control It can include an adapter 24 that corresponds to socket 26 of console 12. Socket 2 6 may be molded to receive the adapter 24, and the adapter 24 fits into the socket 26. When fully installed, there is an electrical connection between the ultrasonic handpiece 14 and the control console 12. The adapter 24 may include electrical contacts corresponding to the electrical contacts of the adapter 24 so that a connection is formed.

[0036] When the ultrasonic handpiece 14 is in operation, the control console 12 generates an AC drive signal. This AC drive signal is supplied to the ultrasonic handpiece 14 via the electrical cable 22. Yes, it is possible. Applying an AC drive signal to the ultrasonic handpiece 14 is done by the ultrasonic handpiece 1 The four chips 16 can be vibrated. More specifically, the main body 18 is a piezoelectric driver. Any cavity containing one or more drivers 28 (three are shown) can be defined. Each driver 28 is made from a material that expands or contracts instantaneously when an alternating current is applied. It is possible. The expansion and contraction of each driver 28 is along the longitudinal axis of the driver 28, that is, And along the axis that extends between the proximal and distal surfaces of the driver 28 This is also acceptable. The driver 28 may be in the shape of a disk and stacked from edge to edge inside the main body 18. They may be placed on top of each other. The insulating disks are placed between adjacent drivers 28, and these It can make firm contact with the driver 28.

[0037] The ultrasonic handpiece 14 receives an AC drive signal from the control console 12. It may be designed to be applied to each of the 28, so that the driver 28 is A It expands and contracts according to the C drive signal. Driver 28 expands and contracts according to the expansion of driver 28 It can be coupled to the tip 16 such that the contraction and expansion cause vibration in the tip 16. Specifically The expansion and contraction of the driver 28 are controlled by the AC drive signal supplied from the control console 12. This can result in forward and backward vibrations along the longitudinal axis of the corresponding tip 16. These vibrations can lead to The distal region 17 of the tip 16 can be vibrated. The distal region 17 is used to process patient tissue. An ultrasound handpiece 14 is applied to patient tissue to bleed and / or excise. It may be a part. The distal region 17 is sized to remove tissue by cutting action. The tip head 19 (for example, Figure 4) may include teeth or grooves that may be formed on it.

[0038] The sleeve 20 may be positioned around the tip 16 and may be formed from plastic. This is also acceptable. The proximal end of the sleeve 20 is designed to allow the sleeve 20 to be released from the distal end of the main body 18. A coupling function part for joining may be formed. The sleeve 20 is placed on the chip 16. When it is attached to the main body 18, it may be spaced radially apart from the tip 16, and the tip 1 The distal region of 6 may be spaced longitudinally apart. Therefore, the ultrasonic handpiece 14 The components are sized so that the chip 16 does not come into contact with the sleeve 20 during normal operation. That's fine.

[0039] The ultrasonic handpiece 14 is used to supply perfusion fluid to the distal region 17 of the tip 16. A path can be defined that extends through at least partially the sonic handpiece 14. For example, the sleeve 20 may include a fitting 30 for receiving the perfusion line. During operation of the ultrasonic handpiece 14, the irrigation fluid is delivered via the mounting fixture 30 to the tip 16 and three It flows through the gap between the b 20 and exits from the open distal end of the sleeve 20. Yes, it is possible. Therefore, the sleeve 20 is in contact with and treated by the ultrasonic handpiece 14. This can facilitate the supply of perfusion fluid to the tissue being treated. In another example, ultrasonic heating The perfusion piece 14 extends from the proximal end of the body 18 to receive perfusion fluid from the perfusion source. It can include a line, and there is a gap between the perfusion line and the distal region 17 of the tip 16. A path can be defined that extends through the body 18 and the sleeve 20. Therefore, During the operation of the ultrasonic handpiece 14, the perfusion fluid flows through the length of the ultrasonic handpiece 14. For example, flowing through the perfusion line, body 18, and sleeve 20, sleeve 2 It can exit through the open distal end of 0.

[0040] Furthermore, the ultrasonic handpiece 14 is designed to perform suction in the distal region 17 of the tip 16. It is also possible to define a path that extends at least partially through the sonic handpiece 14. For example, the ultrasonic handpiece 14 penetrates the tip 16 from the proximal end of the main body 18. A lumen 32 extending to the open distal end of p16 can be defined. During the procedure, in the proximal direction Suction can be performed on lumen 32. Suction is performed on the irrigation flow applied to the surgical site. It can draw in the body and the debris formed by the procedure accompanied by the fluid. The pull mechanism can draw the tissue toward the distal region 17 of the tip 16, thereby, This can enhance the effectiveness of the tip 16 when it comes into contact with tissue for treatment.

[0041] The control console 12 may include a display 34 for presenting information to the operator. It is possible. A non-exclusive example of the information presented is that the control console 12 is currently connected to Identification of ultrasonic handpiece 14 and / or tip 16, ultrasonic tool system 10 The operating state, and the contact of the tip 16 of the ultrasonic handpiece 14 described herein. The characteristics of the organization in which it is located can be cited. In addition, the display 34 allows the operator to control the controls on the screen, etc. A touchscreen that allows for more user input to be provided to the control console 12. It may also be a display screen. The operator interacts with the on-screen controller to control the ultrasound hand Maximum tip displacement level, suction level, and perfusion level in piece 14, The operating parameters of the ultrasonic tool system 10 can be set.

[0042] Furthermore, the ultrasonic tool system 10 has one or more actuators coupled to the control console 12. It may also include a device. When activated by the operator, each actuator controls the control console. The wire 12 sends an AC drive signal to the tip 16 of the ultrasonic handpiece 14 to vibrate the ultrasonic handpiece It can be supplied to the end piece 14. For example, one or more actuators can be supplied to the foot pedal 3 It may include 6. The foot pedal 36 is an adapter that connects to the control console 12. It can be connected wirelessly to the control console 12 via 38, etc. Foot pedal 3 When pressed, component 6 can communicate an operating signal indicating the press to the control console 12. In some cases, the transmitted operating signal depends on the degree to which the foot pedal 36 is pressed. It may change. In response to the reception of the activation signal, the control console 12 The AC drive signal that vibrates the tip 16 according to the current settings is transmitted to the ultrasonic handpiece 14. It can be supplied to.

[0043] The ultrasonic tool system 10 further includes a remote control 40 which is coupled to the control console 12. That's fine. Similar to the touchscreen display 34, the remote control 40 is a control console. The letter 12 may include user-selectable buttons to provide user input. For example, The remote control 40 controls the maximum tip 16 maximum displacement level and suction in the ultrasonic handpiece 14.

[0062] In addition to software embodied by computer executable instructions, console media Mori 60 is the control console 12 or, more specifically, the processor 5 described herein. This may include data that supports the functions, features, processes, and methods of 2. For example, Sole memory 60 transmits various waveform_set signals to the ultrasonic handpiece 14. It can store waveform control data correlated with various supplied AC drive signals. Therefore, the processor 52 accesses this data to provide the desired AC drive signal.

[0063] Furthermore, the control console 12 has one or more electronic memory integrated with the ultrasonic handpiece 14. It may also include a memory reader 76 for communicating with the storage device. Referring to Figure 4, The sonic handpiece 14 identifies the ultrasonic handpiece 14 and / or tip 16.

[0064] For example, the main body 18 of the ultrasonic handpiece 14 is the handpiece (H) that is placed inside it. P) May include memory 78. As a non-limiting example, HP memory 78 is EPRO It may be an M, EEPROM, or RFID tag. Controlling the ultrasonic handpiece 14. Depending on the connection to console 12, processor 52 uses memory reader 76 The data stored in HP memory 78 is read, and based on the data, the control console 12 It can be configured to adjust the operation of the memory. More specifically, the control console 12 can adjust the memory It can include a communication interface such as a coil 80 connected to the 76. The 80 may be integrated with the socket 26 of the control console 12. HP memory 78 is also Similarly, it can be connected to coil 82, and coil 82 is connected to the adapter 24 of cable 22. The body may also be used. The ultrasonic handpiece 14 is connected to the control console 12 via the cable 22. When connected, coils 80 and 82 are aligned and the signal is inductively exchanged. It becomes possible to replace it. Then, the processor 52 connects to HP memory via coils 80 and 82. It can be configured to read data from 78 and write data to HP memory 78.

[0065] More specifically, the memory reader 76 receives a signal across the coil 80 from the processor 52. It can be configured to convert into a readable data signal. Also, the memory reader 76 The data to be written to HP memory 78 is received from processor 52, and the data is HP It is configured to generate a signal that crosses coil 80 so that it is written to memory 78. This is also acceptable. The structure of the memory reader 76 can complement the structure of the HP memory 78. Therefore, continuing with the non-limiting example above, the memory reader 76 is EPROM, EEP Read data from ROM or RFID tags, EPROM, EEPROM, or It may also be an assembly that can write data to an RFID tag.

[0066] In addition to or in place of HP memory 78, the ultrasonic handpiece 14 is It may include a top memory 84. As mentioned above, the chip 16 can be removed from the main body 18. It may be possible, and therefore the main unit 18 is used with various interchangeable chips 16. Different chips 16 may have different structural characteristics and operational limitations. Therefore, HP memory 78 contains data that identifies the main unit 18 and the capacitor of the driver 28. C O It can store operating parameters specific to the main unit 18, including chip memory. The 84 contains data that identifies the chip 16 currently coupled to the main unit 18, and data specific to the chip 16. It can store the operating parameters of the chip 16 and sleeve 20. Since they can be distributed together as a package, the chip memory 84 is placed inside the sleeve 20. It is possible. Chip memory 84 is the same type of memory as HP memory 78 (for example, E This could be a PROM, EEPROM, or RFID tag.

[0067] In accordance with connecting the ultrasonic handpiece 14 to the control console 12, the processor 5 2 was stored in HP memory 78 and chip memory 84 using memory reader 76.

Chip memory 84 It can include the same operating parameter values ​​as HP Memory 78. As long as the value in the terminal differs between HP memory 78 and chip memory 84, the processor Sasser 52 utilizes more restrictive values ​​to control the operation of the ultrasonic handpiece 14. It can be configured as follows. In addition to or instead of this, HP memory 78 and chip memory 8 As long as both of 4 include values ​​in the predetermined operating parameters, the processor 52 will Based on the combination of values ​​stored in Mori (for example, the sum of the values), the ultrasonic handpiece 1 To manage the operation of step 4, derive a value (for example, the maximum drive current in the AC drive signal current). It can be configured to do so.

[0068] Similar to the HP memory 78, the processor 52, via the memory reader 76 and coil 80 This involves reading data from the chip memory 84 and writing data to the chip memory 84. This is possible. In particular, the main body 18 has two conductors 8 that extend from the proximal end to the distal end of the main body 18. It can include 6. The proximal end of the conductor 86 is integrated with the adapter 24 of the cable 22. It may be coupled to the coil 82. The distal end of the conductor 86 is the distal end of the main body 18. It may be coupled to another coil 88 located at the proximal end of the sleeve 20. Il 90 may be placed. Sleeve 20 is placed around chip 16 and body 18 Once installed, coils 88 and 90 are aligned, and the signal is inductively transmitted. It will become replaceable. The main unit 18 is connected to the control console 12 via the cable 22. Then, coils 80 and 82 are also aligned, allowing for inductive signal exchange. Then, the processor 52 is powered by coils 80, 82 and coils 88, 90. Data is read from the chip memory 84 across the conductor 86 via the provided inductive communication. This allows data to be written to the chip memory 84.

[0069] Furthermore, one or more electronic memory storage devices of the ultrasonic handpiece 14 are used in the ultrasonic tool system When the Tem 10 is operating in probe mode, the ultrasonic handpiece 14 is in contact It can also store data to identify the characteristics of the organization. As mentioned above, the process S52 is described in more detail below when the ultrasonic handpiece 14 is in contact with the tissue. Based on identified operating characteristics related to the ultrasonic handpiece 14, such as the modulated mechanical resistance, It can be configured to identify the characteristics of the tissue it has come into contact with. However, the given body 18 It can be used with different interchangeable chips 16, and the main unit 18 and chip 16 Different combinations can exhibit different basic operating characteristics. In other words, different ultrasonics The wave handpiece 14 vibrates in an unloaded state, i.e., in air, and does not come into contact with any tissue. When operating without a load, it may exhibit different operating characteristics. For example, when operating under no load... The operating characteristics of one ultrasonic handpiece 14 at that time are approximately 300 ohms, and the other ultrasonic The unloaded modulation mechanical resistance of the sonic handpiece 14 is in the range of 600 ohms to 800 ohms. It may be within the range. Therefore, the modulation mechanical resistance of the ultrasonic handpiece 14, etc. The significance of the identified operational characteristics of piece 14 with respect to the characteristics of the contacted tissue is that when the tissue is in contact... This may vary depending on the specific ultrasonic handpiece 14 used.

[0070] Therefore, one or more electronic memory storage devices of the ultrasonic handpiece 14 are used for ultrasonic handpieces. Data showing the no-load modulated mechanical resistance specific to the handpiece 14, etc. The operating characteristics of the ultrasonic handpiece 14, which are identified when in contact with patient tissue, are normalized. It can store normalized data specific to the ultrasonic handpiece 14 for this purpose. The HP memory 78 can store the no-load modulated mechanical resistance specific to the main unit 18, and Alternatively, the chip memory 84 stores the unloaded modulated mechanical resistance specific to the chip 16. This can be done. As will be explained in more detail below, this data is used during manufacturing by ultrasonic handpieces. The components of S14 can be identified by testing the ultrasonic tool system. When 10 is operating to probe patient tissue, processor 52 is HP memory Read this data from 78 and / or chip memory 84 and make contact based on it It can be configured to normalize the identified operating characteristics of patient tissue.

[0071] Furthermore, the processor 52 is configured to drive the display 34 of the control console 12. They may be combined and configured. Specifically, the processor 52 presents on the display 34 To generate information and user interface (UI) components for that purpose. It may be configured as follows: such information shown on the display 34 is the main body 18 and Information for identifying the chip 16, information for describing the operating state of the ultrasonic tool system 10, and information for identifying the characteristics of the patient tissue contacted by the chip 16 when the control console 12 is operating in the probing mode can be cited. When the display 34 is a touch screen display, the processor 52 can also be configured to cause images of buttons such as the aforementioned virtual mode setting switches and other user-selectable components to be shown on the display 34. By interacting with the buttons and other user-selectable components, the operator can set the desired operating parameters of the ultrasonic tool system 10.

[0072] In addition, the processor 52 is coupled to mode setting switches of the ultrasonic tool system 10 such as the foot pedal 36, the remote control 40, and the switch 43 integrated with the ultrasonic handpiece 14, receives user input from such devices, and can process such input accordingly. For example, when the ultrasonic handpiece 14 is coupled to the control console 12, the processor 52 can be communicably coupled to the switch 43 integrated with the ultrasonic handpiece 14 via one or more electrical contacts 92 integrated with the socket 26 of the control console 12 and one or more electrical contacts 94 integrated with the adapter 24 coupled to the ultrasonic handpiece 14. In this case, the processor 52 can be configured to monitor the state of the switch 43 to determine whether the ultrasonic tool system 10 is set to operate in the probing mode or the ablation mode.

[0073] ​​​​​​​​​​​​Further, the processor 52 may be configured to drive the speaker 96 of the control console 12. For example, depending on the identification of the characteristics of the patient tissue in contact with the chip 16, the processor 52 may be configured to reproduce distinct sounds via the speaker 96 to indicate the tissue characteristics to the operator.

[0074] FIG. 5 shows a method 100 for probing patient tissue using the ultrasonic handpiece 14 to identify tissue characteristics such as characteristics indicating whether the tissue is healthy or unhealthy. The method 100 can be executed by the control console 12, such as under the instruction of the processor 52. More specifically, the processor 52 may be configured to cause the control console 12 to execute the method 100 via software stored in the console memory 60.

[0075] In block 102, the ultrasonic tool system 10 can determine whether it is set to the probing mode or the ablation mode. In the ablation mode, the control console 12, or more specifically the processor 52, may be configured to generate an AC drive signal that causes sufficient vibration of the chip 16 to excise the contacted tissue and supply it to the ultrasonic handpiece 14. In the probing mode, the control console 12, or more specifically the processor 52, may be configured to generate an AC drive signal that causes insufficient vibration of the chip 16 to excise the contacted tissue and supply it to the ultrasonic handpiece 14. In the latter mode, the vibration of the chip 16 can push or pull the contacted tissue without causing damage.

[0076] The processor 52 selects one of these operating modes based on user input. It may be configured to identify block 102. More specifically, processor 52 By monitoring the status of the mode setting switch, the ultrasonic tool system 10 is professional The system is configured to determine whether it is set to ablation mode or savage mode. Even if it is done, the mode setting switch is on the touchscreen display 34, footpeg Dal 36, remote control 40, or ultrasonic handpiece 14 (for example, switch 43) It may be integrated with at least one of these devices. Specifically, the user may use these devices It can interact with one of them and indicate one of the operating modes to the processor 52. ru.

[0077] For example, the touchscreen display 34 allows you to select between operating modes on the screen. Interactive elements (e.g., buttons) can be displayed, and the remote control 40 can also, Similarly, it can include interactive control elements for making selections. Foot pedal The 36 foot pedal can be pressed in either probing mode or ablation mode. The operating mode is determined by a processor 52 configured to determine which of the two options corresponds to. This may allow the user to select one of the following: for example, from foot pedal 36 to processor 5 Depending on whether the signal received by 2 indicates a step below the set threshold, the program The Sessa 52 allows the user to operate the ultrasonic tool system 10 in probing mode. It can be configured to specify that it desires to do so from the foot pedal 36 to the processor 52. Therefore, in response to the received signal indicating a penetration exceeding a set threshold, the processor 52 allows the user to operate the ultrasonic tool system 10 in ablation mode. It can be configured to specify what is desired. Alternatively, the foot pedal 36 is an ultrasonic tooth The system 10 may have separate foot-operated elements for operation, on the other hand This is for operating the ultrasonic tool system 10 in ablation mode, and other This is for operating the ultrasonic tool system 10 in probe mode. The switch 43, which is integrated with the handpiece 14, activates the probing mode when the switch 43 is pressed. Configure the system so that when selected, and switch 43 is released, the ablation mode is selected. It is possible.

[0078] In block 104, the ultrasonic tool system 10 operates in ablation mode. In response to the determination that it has been set to do so (the "ablation" branch in block 102), The ultrasonic handpiece 14 can be operated in ablation mode. In particular, the process The 52 controls the AC drive signal that causes the tip 16 to vibrate for excising patient tissue. The console 12 can be configured to supply the ultrasonic handpiece 14. In 3 in-mode, the AC drive signal supplied to the ultrasonic handpiece 14 is 100 microns or more. Vibration cycles with relatively high peak-to-peak displacements, such as 00 microns or less This can bring about motion in the distal region of tip 16. In other words, ultrasound in ablation mode. The AC drive signal supplied to the handpiece 14 extends the distal region of the tip 16 to 100 microns. It can be displaced back and forth along a movement path of 300 microns or less. Similarly, abrasion In 0 mode, the AC drive signal supplied to the ultrasonic handpiece 14 is 50 milliamperes or more. a mechanical current i with an amplitude of 150 milliamperes or less M such as a relatively high mechanical current i M can bring about. The generation of the AC drive signal by the control console 12 in ablation mode is performed as described in the applicant's U.S. Patent No. 10,016,209 and may be carried out, and the content of U.S. Patent No. 10,016,209 is incorporated herein by reference in its entirety into this application .

[0079] In some implementations, operating the ultrasonic handpiece 14 in ablation mode at block 104 may include suction at the distal region 17 of the chip 16 through a corresponding path defined by the ultrasonic handpiece 14, and also supplying fluid to the distal region 17 of the chip 16 through a corresponding path defined by the ultrasonic handpiece 14. In other words, depending on the specification that the ultrasonic tool system 10 is set to operate in ablation mode, the control console 12 may be configured to initiate suction and perfusion fluid supply to the ultrasonic handpiece 14. Conversely, when the ultrasonic tool system 10 is set to operate in the probing mode, the control console 12 may be configured to maintain the suction and perfusion functions in an inactive state .

[0080] At block 106, in response to a determination that the ultrasonic tool system 10 is set to operate in the probing mode (the "probing" branch of block 102), while the distal region of the chip 16 is in contact with the patient tissue, a chip for probing the patient tissue ​​​​​​​​​An AC drive signal that causes vibration of the 16 can be supplied to the ultrasonic handpiece 14. Figure 6 shows AC drive signal 1 can be supplied to the ultrasonic handpiece 14 in probing mode. 26 examples are shown. As shown in the illustrated example, the AC drive signal 126 is transmitted to the ultrasonic handpiece 1 It can include components at the resonant frequency and components at the probe frequency. The resonant frequency can be significantly lower than the resonant frequency. For example, the resonant frequency is It may be approximately 25kHz (for example ±1kHz), and the probing frequency may be approximately 4Hz (e.g. For example, it may be ±1Hz. More specifically, the AC drive signal 126 is the probing frequency. A resonant frequency with an amplitude that changes according to the wavenumber, including a base signal such as a sine wave signal. Therefore, it is possible to supply the ultrasonic handpiece 14 in probing mode. The AC drive signal 126 may also be an amplitude-modulated signal.

[0081] The AC drive signal causes vibrations of the tip 16 that are insufficient for excising patient tissue, instead It can be configured to push or pull patient tissue without causing further damage. In particular, the AC drive signal causes vibrations to push and pull the tissue, but it does not excise. This occurs when the control console 12 is operating in ablation mode. This can produce vibrations in the distal region of the tip 16 that are smaller in magnitude and velocity than the vibrations. For example, the AC drive signal supplied in probing mode is less than 100 microns. Vibrations with relatively low peak-to-peak displacements and vibration cycles are transmitted to the far end of the tip 16. This can be brought to position region 17. In other words, while operating in probing mode, the chip 16 may vibrate back and forth along a changing trajectory of up to 100 microns. As shown, the AC drive signal supplied to the ultrasonic handpiece 14 in ablation mode is 5 Mechanical current i with a fluctuation amplitude of 0 milliamperes or less M relatively low mechanical current i M possess This can be done. For example, the AC drive signal is 5 according to the probing frequency. It varies between 0 milliamperes and 25 milliamperes, or between 10 milliamperes and 5 milliamperes. A mechanical current i with an amplitude that varies between amperes M It can be configured to bring about.

[0082] The processor 52 supplies the ultrasonic handpiece 14 in probing mode. The system may be configured to cause the control console 12 to generate the AC drive signal. In particular, the processor 52 is, for example, the minimum frequency read from the electronic memory storage device of the ultrasonic handpiece 14. The AC drive signal is swept between the wavenumber and the maximum frequency, and the frequency at which the maximum mechanical current i is reached is determined. M even By specifying the frequency f such that equation (2) is satisfied, By doing so, the ultrasonic handpiece 14 can be configured to track its resonant frequency. ru.

[0083] Subsequently, the processor 52 uses, for example, a DDS to generate a signal proportional to the desired AC drive signal. Wavefo generates a wavefo at the signal generator 56 that receives an AC signal crossing the primary winding 62 of the transformer 58. It can be configured to generate an rm_set signal and communicate with the signal generator 56. Specifically, The processor 52 receives mechanical current i M (For example, 50 milliamperes, 10 milliamperes) A mechanical current i with an amplitude equal to the desired maximum amplitude is applied.M At the resonant frequency accompanied by the amplitude that brings about this A waveform-set signal is passed through the signal generator 56 to generate a sine wave-based sine waveform. Believe in a sine wave with a probing frequency that varies between 1 and a value between 0 and 1 (e.g., 0.5). A modulated waveform is generated, and this modulated waveform is multiplied by the base signal to obtain a proportional A signal across the terminals of the primary winding 62. It can generate a C signal.

[0084] In another example, such as when the signal generator 56 is an amplifier, the processor 52 uses DDS. Using methods such as those mentioned above, a waveform-set signal proportional to the desired AC drive signal is generated. It may be configured in such a way. In particular, the processor 52 has a mechanical current i M The most desirable maximum vibration for A mechanical current i with an amplitude equal to its width M At the tracked resonant frequency having an amplitude that brings about the result A sinusoidal base signal is generated, that is, a sinusoidal modulated waveform at the probing frequency. These signals are multiplied to generate an amplitude-modulated signal proportional to the desired AC drive signal. It can be configured. The processor 52 then uses this signal as a waveform-set signal. It may also be configured to communicate with the signal generator 56, thereby amplifying the signal. A desired AC drive signal can be generated that crosses the secondary winding 64 of the transformer 58.

[0085] In block 108, the voltage v of the supplied AC drive signal s and current i s , Chip Measurements can be taken while the distal region 17 of the probe 16 is in contact with the patient's tissue. Specifically, the process The 52 uses voltage sensors such as the regeneration coil 68 and the voltage measurement circuit 70 to ultrasonically analyze sound. The voltage v across the ends of the wave handpiece 14 sIt can be configured to measure a coil Using current sensors such as 72 and the current measurement circuit 74, mark the ultrasonic handpiece 14. The current i s It may be configured to measure A. Measured voltage v of the C drive signal s and current i s Based on this, mechanical current i M To estimate This is possible. Specifically, the processor 52 measures the measured voltage v s and current i s to the above By applying this to equation (1), the mechanical current i M It can be configured to calculate the following. Figure 7 The measured voltage v s and the calculated mechanical current i M voltage waveforms corresponding to each 12 8 and the mechanical current waveform 130 are shown.

[0086] During operation of the ultrasonic handpiece 14 in probing mode, the processor 52 controls the mechanical electrical Flow M The mechanical current i is at the resonant frequency of the ultrasonic handpiece 14. M The goal (for example, 5 (Amplitude varying between ~10 milliamperes, amplitude varying between 25 and 50 milliamperes) It can be configured to continuously check that it has a size equal to a certain value. For example, Pro The Sessa 52 is determined by the result of equation (1) when the mechanical current i M Whether it is substantially equivalent to the goal, then It may be configured to perform a cycle that determines whether equation (2) is substantially applicable. The result of equation (1) is the mechanical current i M If it is not substantially equal to the target, processor 52 By adjusting the amplitude of the waveform_set signal, etc., the result of equation (1) and the mechanical current i MThe voltage of the AC drive signal v is reduced so that the difference between it and the target is reduced. S Adjustable configuration It is possible. Furthermore, if equation (2) is not substantially applicable, the processor 52 will wave By adjusting the frequency of the form_set signal, the relationship in equation (2) can be substantially applied. It can be configured to adjust the frequency of the AC drive signal so that it does so.

[0087] Referring again to method 100, the voltage v of the supplied AC drive signal s and current i s to measure Determined, mechanical current i M In accordance with the calculation, processor 52 controls ultrasonic handpiece 1 Identify the operational characteristics related to 4, and the characteristics of the patient tissue in contact with the ultrasonic handpiece 14. It may be configured to identify a modulated mechanical resistor. In particular, the processor 52 is a modulated mechanical resistor as specified herein.

[0088] More specifically, in block 112, the voltage v at the probing frequency is... s and mechanical current i M The amplitudes of each, and the voltage v s and mechanical current i M The phase difference between and is The processor 52 can determine a voltage v that corresponds to the probing frequency. s Oh and mechanical current i M By detecting each envelope, the amplitude and phase difference are specifically It can be configured to set a specific value. For example, processor 52 squares the signal and performs a low-pass filter. Direct Fourier Transform (DFT) which processes or applies a Hilbert transform filter to a signal. By implementing the algorithm, we can identify the upper envelope of these signals. It can be configured as follows. Figure 7 shows the voltage envelope corresponding to the upper envelope of the voltage waveform 128. The waveform 132 and the mechanical current envelope corresponding to the upper envelope of the mechanical current waveform 130 The voltage envelope waveform 132 and are shown as shown in the illustrated example. Each of the mechanical current envelope waveforms 134 is a sine wave at the probing frequency. It is possible.

[0089] Subsequently, the processor 52 specially determines the amplitude of each envelope and the phase difference between the envelopes. By defining this, the amplitude and phase difference at the probing frequency are determined. This can be achieved. The processor 52 performs peak detection to identify the maximum and minimum values ​​of the envelope. Execute the output algorithm, subtract the minimum value from the maximum value, and divide the result of the subtraction by 2, whereby it can be configured to identify the amplitude of each envelope. The processor 52 subtracts the time index corresponding to the maximum value of one envelope from the next larger time index corresponding to the maximum value of the other envelope, and divides the result of the subtraction by the period of the envelope (e.g., the reciprocal of the probing frequency) to identify the phase difference between the envelopes. It can be configured to do so.

[0096] Alternatively, the no-load modulated mechanical resistance inherent to the ultrasonic handpiece 14 is HP memory 78 and / or one or more electronic memory chips integrated with the ultrasonic handpiece 14, such as chip memory 84 Identified from data pre-stored in Mori memory and read from electronic memory storage. It is also possible. The variation in unloaded modulated mechanical resistance between different ultrasonic handpieces 14 is mainly due to ultrasonic This may be due to the use of different tips 16 within the wave handpiece 14. Therefore, ultrasonic handpiece The data for identifying the unloaded modulated mechanical resistance in piece 14 is obtained from the ultrasonic handpiece. It can be stored in the chip memory 84 distributed together with the chip 16 of S14. For example, chip During the manufacturing of chip 16, the unloaded modulation mechanical resistance of chip 16 connects chip 16 to the body 18. An ultrasonic handpiece 14 is formed, and this ultrasonic handpiece 14 is connected to the control console 12. In addition to bonding, when the chip 16 is not in contact with the tissue, this control console 12 Execute blocks 106-114 to determine the unloaded modulated mechanical resistance in chip 16. This can be identified by doing so. Next, this no-load modulation resistor is distributed together with the chip 16. It can then be stored in the chip memory 84. After that, the ultrasonic handpiece with chip 16 -14 is connected to the control console 12, and the control console 12 prepares for operation. Depending on whether the power is on, processor 52 will receive no load from chip memory 84. The mechanical resistance is read, and this value is used in the normalized no-load variable of the ultrasonic handpiece 14. It can be configured to be used as a mechanical resistor.

[0097] Alternatively, the HP memory 78 and chip memory 84 of the ultrasonic handpiece 14 are either It also stores data to identify the no-load modulated mechanical resistance in the ultrasonic handpiece 14. It is possible. Specifically, the HP memory 78 of the main unit 18 is the unloaded modulator of the main unit 18. It can store data indicating mechanical resistance, and the chip is distributed together with the chip 16. Mori 84 can store data indicating the unloaded modulated mechanical resistance in chip 16. The no-load modulated mechanical resistance in the main body 18 controls the main body 18 without the chip 16. The block 10 is connected to the sole 12 and does not come into contact with the body 18 and tissue, and is connected to the control console 12. This can be identified during manufacturing by executing steps 6-114. No load on chip 16. The modulated mechanical resistor connects the tip 16 to the main body 18 to form the ultrasonic handpiece 14. The ultrasonic handpiece 14 is connected to the control console 12, and the ultrasonic handpiece 14 is entrusted with Without contacting the organization of the intent, the control console 12 will execute blocks 106-114. The no-load modulated mechanical resistance of the ultrasonic handpiece 14 is identified, and this no-load modulated mechanical resistance is used to determine the Subtracting the already identified unloaded modulated mechanical resistance in body 18, the unloaded resistance in chip 16 The load modulation mechanical resistance can be identified during manufacturing. Subsequently, the main body 18 and The ultrasonic handpiece 14 with the tip 16 is connected to the control console 12, and the operation preparation In response to the power being turned on to the control console 12 for safety reasons, the processor 52, Read the no-load mechanical resistance specific to the main unit 18 from HP memory 78, and from chip memory 84 The unloaded mechanical resistance specific to chip 16 is read, and based on the read data ( For example, the ultrasonic handpiece 14 has a unique no-load modulated mechanical resistance (to sum the read no-load modulated mechanical resistances).

[0099] Referring again to Figure 5, in block 118, tissue characteristics can be shown to the operator. The processor 52 provides, for example, a display 34 or an integrated view with the ultrasonic handpiece 14. Visual indicators corresponding to tissue characteristics identified via sensory indicators, speaker 96 Auditory indicators corresponding to tissue characteristics identified via and / or ultrasonic sensors Provides a tactile indicator corresponding to tissue characteristics identified via the vibration of the dopiece 14. It can be configured as follows: To provide tactile feedback, the processor 52 excises tissue. This is insufficient, and the distinct sensations that can be felt by the operator holding the ultrasonic handpiece 14 The configuration is configured to supply an AC drive signal that causes a vibration pattern to the ultrasonic handpiece 14. It is possible. For example, processor 52 includes an on-pulse separated by an off-period. The C drive signal may be configured to be supplied to the ultrasonic handpiece 14, thereby This can result in separated ultrasonic vibrations of the tip 16 that are insufficient for tissue excision.

[0100] If the identified characteristic indicates an organization type corresponding to a binary organization state (for example, the characteristic is This indicates whether the contacted tissue should be excised or not, and the characteristic is that the contacted tissue is healthy tissue. It indicates whether or not, and the characteristic is whether or not the contacted tissue is of the type defined by the operator. (to indicate) the processor 52 if the characteristic corresponds to one of the binary condition states It provides a display of the identified characteristics, and if the characteristics correspond to other states of the binary condition, it is displayed in the table. It may be configured not to provide an indication. For example, it may identify that the contacted tissue is healthy. Even if the characteristic indicates that the processor 52 is configured not to provide a display of that characteristic, Often, if the identified characteristics indicate that the contacted tissue is unhealthy, the processor 52 will It is configured to provide a visual, auditory, and / or tactile representation of the characteristics as described above. It is possible that the processor 52, regardless of the state represented by the characteristic, It may be configured to provide a display.

[0101] The identified characteristics correspond to tissue conditions of varying severity (e.g., various levels of unhealthy tissue). When indicating the corresponding organizational type, processor 52 uses the severity indicated by the characteristics. It can be configured to provide a display of identified characteristics that are changed by touch. For example, by touch If one identified characteristic indicates that the health grade of the tissue is low, the processor 52 will It may be configured to provide one auditory, visual, and / or tactile indication, Furthermore, if another identified characteristic indicates a lower health grade of the contacted tissue, the process SA52 indicates a lower health grade compared to the previous health grade, with different auditory, visual, and It may be configured to provide a visual and / or tactile indication. Some non-limiting examples include Rossessa 52 displays a larger size on the display 34 than the previous health grade. By displaying this, it is possible to achieve higher volume levels at higher frequencies than the previous health rating. Alternatively, by emitting a beep sound from speaker 96, and / or from the previous health rating The sound wave handpiece 14 is vibrated to generate on-pulses at a higher frequency. This can be configured to indicate a lower health grade.
