1. Field of the Invention
The present invention relates to a minimally invasive medical manipulation apparatus, and particularly relates to a minimally invasive medical manipulation apparatus having an energy treatment instrument which is used under endoscopic observation.
2. Description of the Related Art
Conventionally as minimally invasive medical manipulation, operations under endoscopic observation using endoscope images and operations under ultrasound observation using ultrasound images have been performed.
For example, Japanese Patent Application Laid-Open Publication No. 8-52153 discloses an electric scalpel device which guides a snare to a tip end of an endoscope through a forceps channel of the endoscope, passes a current to an affected part from the snare, and treats the affected part.
Further, Japanese Patent Application Laid-Open Publication No. 2000-312681 discloses an ultrasound operation system which drives a therapeutic ultrasound treatment instrument under ultrasound observation, and treats an affected part.
When energy treatment instruments such as the electric scalpel device and therapeutic ultrasound instrument as described above are used in the minimally invasive medical manipulation using the endoscope images and ultrasound images, a problem occurs in which the treatment energy at the time of drive of the energy treatment instruments becomes noise, and has an influence on the images of the endoscope images and ultrasound images.
Thus, for example, in the ultrasound operation system of the aforementioned Japanese Patent Application Laid-Open Publication No. 2000-312681, an art is disclosed in which when the ultrasound treatment transducer of a therapeutic ultrasound treatment instrument is driven, the output level of the ultrasound treatment transducer is reduced at the timing of drive of the ultrasound observation transducer, and thereby, the resistance to noise due to treatment energy is enhanced.
Meanwhile, in recent years, as shown in, for example, Japanese Patent Application Laid-Open Publication No. 6-114000, Japanese Patent Application Laid-Open Publication No. 2006-192201, or the like, an active endoscope and an active instrument tool having active functions capable of realizing maneuverability at desired degrees of freedom have been disclosed.
An example of an active endoscope and an active treatment instrument will be described with use of
More specifically, an insufflating needle is inserted into an abdominal part 88 first, and the inside of an abdominal cavity 89 is insufflated. Next, the articulated micro manipulator 81 is inserted from the insufflated hole through a trocar 90, an organ is grasped with the micro gripper 82 with a tactile sensor, and the operative field is ensured.
Next, when a gall bladder is extracted, the gall bladder is lifted with the micro gripper 82. After a bile duct and a blood vessel are ligated with the micro clip 83 as shown in
Observation of the inside of the abdominal cavity 89 is performed with the stereoscopic endoscope 84 mounted on the articulated micro manipulator 81.
At this time, an operator performs the operation with the remote control operation mechanism 86 while watching the stereoscopic image projected on the three-dimensional display device 87.
The minimally invasive intraperitoneal surgical operation apparatus of such a configuration only has to make one insertion hole in the abdominal part 88 of a patient, and therefore, has the advantage of having extremely low invasiveness to a patient. Further, an operator can perform an intraperitoneal surgical operation while watching the stereoscopic image of the inside of the abdominal cavity 89, and therefore, the operator can perform an operation with the sense similar to a surgical operation by abdominal section.
As shown in
A medical manipulation apparatus of the present invention is configured by including
a remote active treatment section including a remote treatment instrument remotely treating a subject,
an active control section controlling the remote active treatment section,
an energy treatment section performing energy treatment for the subject, and
a control section detecting an energy output state of the energy treatment section, and changing active control of at least the remote active treatment section based on the energy output state.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in
The energy output device 10 includes an energy instruction input device 11, and the energy instruction input device 11, the energy treatment instrument 9 and the energy output device 10 configure energy treatment means such as an electric scalpel device and an ultrasound treatment device, which performs treatment modes (hemostasis, dissection or coagulation mode or the like) for an affected part.
Further, the active endoscope 2 is configured by including an image pickup device (not illustrated) such as a CCD or C-MOS sensor or the like at a distal end, for example, and having an endoscope active mechanism section 12 as remote active bending means having an active function having a desired degree of freedom. The endoscope active mechanism section 12 is controlled so as to perform a desired operation by an active endoscope control section 14 of the active mechanism control device 5 based on an instruction signal from an active endoscope instruction input device 13 such as a joy stick, for example, which is connected to the active mechanism control device 5.
Similarly, the active treatment instrument 3 is configured by including a small-diameter insertion section (not illustrated) which can be inserted through the treatment instrument channel (not illustrated) of the active endoscope 2, for example, and can be protruded from a distal end, and having a treatment instrument active mechanism section 15 as remote active treatment means having an active function having a desired degree of freedom. The treatment instrument active mechanism section 15 is controlled to perform a desired operation by an active treatment instrument control section 17 of the active mechanism control device 5 based on an instruction signal from an active treatment instrument instruction input device 16 such as a joy stick, for example, which is connected to the active mechanism control device 5.
The light source device 6 is a light source section which supplies illumination light to the active endoscope 2. Further, the video processor 7 is an image processing section which drives the image pickup device (not illustrated) of the active endoscope 2, performs signal processing for an image pickup signal and displays an endoscope image on the display device 8.
Further, the active mechanism control device 5 includes a state detecting section 20 which detects an output state of energy supplied to the energy treatment instrument 9 by a status signal from the energy output device 10.
The state detecting section 20 controls the energy output device 10, the active endoscope control section 14 and the active treatment instrument control section 17 based on the output stage of the energy to the energy treatment instrument 9. The details of control of the state detecting section 20 will be described later.
The operation of the endoscope system apparatus 1 of the present embodiment thus configured will be described.
The energy output device 10 supplies energy output as shown in
The output waveform of
Meanwhile, the waveforms of
The endoscope system apparatus 1 inserts the active endoscope 2, the active treatment instrument 3 and the energy treatment instrument 9 into a body cavity and carries out manipulation under endoscopic observation.
Subsequently, when treatment to an affected part is started by the energy instruction input device 11, the active mechanism control device 5 determines whether or not a control instruction for the active mechanism is given by an operator by detecting the instruction signal from the active endoscope instruction input device 13 or the active treatment instrument instruction input device 16 in the active endoscope control section 14 or the active treatment instrument control section 17 in step S1 as shown in
When the control instruction for the active mechanism is present, the active mechanism control device 5 acquires the energy output state information from the state detecting section 20 by the status signal from the energy output device 10 in step S2.
More specifically, in step S2, the state detecting section 20 detects first information of whether energy output is executed from the energy output device 10 or not, and second information of whether the state waveform of the output waveform when the energy is outputted is a stable state waveform or an unstable state waveform as the energy output state information, by the status signal.
The state detecting section 20 detects the second information of the energy output state information as the information based on the changing speed of the waveform, but the second information is not limited to this. The second information may be the information indicating whether or not the output is of a predetermined amplitude or more (for example, the waveform of a predetermined amplitude or more=unstable state waveform, the waveform of an amplitude less than the predetermined amplitude=stable state waveform), and may be the information combining the changing speed and amplitude of the waveform.
Subsequently, in step S3, the active mechanism control device 5 determines whether or not the energy output device 10 is under energy output (energy output is ON) based on “the information whether or not energy output is executed from the energy output device 10” which is the first information of the energy output state information detected by the state detecting section 20.
Upon determining that it is under energy output (energy output is ON), the active mechanism control device 5 determines whether the state waveform of the output waveform is a stable state waveform or an unstable state waveform by the second information of the energy output state information detected by the state detecting section 20 in step S4.
Upon determining that the state waveform of the output waveform is a stable state waveform, the active mechanism control device 5 controls the active endoscope control section 14 or the active treatment instrument control section 17, and starts control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 in step 5. If it is determined that it is not under energy output (energy output is ON) in the above described step S3, the active mechanism control device 5 still proceeds to step S5.
Subsequently, in step S6, the active mechanism control device 5 repeats the processing of the above described steps S1 to S5 until the active mechanism control device 5 detects termination of control of the active mechanism (termination of treatment by the endoscope system apparatus 1).
More specifically, when it is not under energy output (energy output is ON), or when the state waveform of the output waveform of the energy output is a stable state waveform, noise which is likely to have an influence on control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 does not occur from the energy output device 10, and therefore, the active mechanism control device 5 executes control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 in step S5.
On the other hand, upon determining that the state waveform of the output waveform is an unstable state waveform in step S4, the active mechanism control device 5 transmits an energy output control command to the energy output device 10 in step S7.
The energy output control command is a command for ordering stoppage of energy output or restriction of the output level for a certain predetermined period to the energy output device 10. When the energy output device 10 receives the energy output control command from the active mechanism control device 5, the energy output device 10 executes stoppage of energy output or restriction of the output level for a certain predetermined period.
When the active mechanism control device 5 transmits the energy output control command to the energy output device 10, the active mechanism control device 5 starts timing control of the period of stoppage of energy output or restriction of the output level for a certain predetermined period in the energy output device 10 in step S8, and proceeds to step S5.
More specifically, upon determining that the state waveform of the output waveform is an unstable state waveform, the active mechanism control device 5 performs stoppage of the energy output of the energy output device 10 or restriction of the output level for a certain predetermined period, and executes control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 based on the timing of the certain predetermined period in step S5.
Thus, in the present embodiment, the state detecting section 20 detects the energy output state information, whereby when it is not under energy output (energy output is ON), or when the state waveform of the output waveform of the energy output is a stable state waveform, noise which is likely to exert an influence on control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 does not occur from the energy output device 10, and therefore, reliable and stable control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 can be performed.
Further, the state detecting section 20 detects the energy output state information, whereby even when the state waveform of the output waveform is an unstable state waveform, noise which is likely to exert an influence on the control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 does not occur from the energy output device 10 since stoppage of energy output of the energy output device 10 or restriction of the output level is performed for a certain predetermined period, and reliable and stable control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 can be performed based on the timing of the certain predetermined period.
The endoscope system apparatus 1 of the present embodiment can perform control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 reliably and stably without receiving the influence of the energy output device 10 by the processing of the aforementioned active mechanism control device 5, and therefore, has the effect of being capable of enhancing noise resistance in the energy treatment easily at low cost.
In the present embodiment, the state detecting section 20 detects the state specified based on the differential value of the output waveform as an example of the energy output state, but the state is not limited to this, and for example, the state detecting section 20 may detect the state specified based on at least any one of the above described differential value, the integrated value, the amplitude value and the frequency of the output waveform as the energy output state.
Embodiment 2 is substantially the same as embodiment 1, and therefore, only the different point will be described. The same components are assigned with the same reference numerals, and description thereof will be omitted.
As shown in
An operation of the endoscope system apparatus 31 of the present embodiment thus configured will be described.
Ordinarily, the endoscope 32 has a release function for storing a still image of the endoscope image which the endoscope 32 picks up. However, when a still image is stored by executing the release function during output of the energy of the energy output device 10, the influence of the noise due to energy output of the energy output device 10 is reflected on the stored still image, and a desired still image is not likely to be stored with desired image quality, but in the present embodiment, storage of a still image is executed by executing the processing as shown in
More specifically, as shown in
In step S11, the video processor 7 determines whether or not the release switch not illustrated of the endoscope 32 is operated and a release instruction is given. Upon determining that the release instruction is given, the video processor 7 executes processing of storing the still image of the endoscope image by known release processing in step S12. Subsequently, the video processor 7 repeats the processing of steps S2 to S4, S11 and S12 until the video processor 7 detects termination of inspection in step S13.
On the other hand, upon determining that the state waveform of the output waveform is an unstable state waveform in step S4, the video processor 7 proceeds to step S14.
In step S14, the video processor 7 disables (unable to perform storage processing) storage processing of the still image of the endoscope image, and proceeds to step S13.
Thus, in the present embodiment, the energy output state of the energy output device 10 is detected at the time of image storage, and executable/unexecutable of the image storage is controlled in accordance with the output stage. Therefore, the present embodiment has the effect of being capable of reliably and stably executing release processing without receiving the influence of the energy output device 10, and being capable of enhancing noise resistance in the energy treatment easily at low cost.
Embodiment 3 is substantially the same as embodiment 1, and therefore, only the different point will be described. The same components are assigned with the same reference numerals, and description thereof will be omitted.
In the present embodiment, as shown in
In the present embodiment, as shown in
Next, when the output of the energy is ON, the output waveform recognition section 41 analyzes the output waveform of the energy to the energy treatment instrument 9 in step S22, and determines the waveform state (a stable state waveform or an unstable state waveform). When the output of the energy is not ON, the present processing proceeds to step S24.
Subsequently, the output waveform recognition section 41 outputs the determined waveform state (a stable state waveform or an unstable state waveform) to the active mechanism control device 5 as the energy output state information in step S23. The output waveform recognition section 41 repeats the processing until the output waveform recognition section 41 detects termination of the energy output control in step S24.
Meanwhile, the active mechanism control device 5 executes the processing of steps S1 to S6 described in embodiment 1 based on the energy output state information from the output waveform recognition section 41 as shown in
In the present embodiment, upon determining that the state waveform of the output waveform is an unstable state waveform in step S4, the active mechanism control device 5 disables the active mechanism control in step S25 to return to step S1.
Thus, in the embodiment, the output waveform recognition section 41 analyzes/recognizes energy output, whereby control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 can be performed reliably and stably without receiving the influence of the energy output device 10 as in embodiment 1, and therefore, the embodiment has the effect of being capable of enhancing noise resistance in the energy treatment easily at low cost.
Embodiment 4 is substantially the same as embodiment 3, and therefore, only the different point will be described. The same components are assigned with the same reference numerals and description thereof will be omitted.
In the present embodiment, as shown in
In the present embodiment, as shown in
In step S32, the output waveform recognition section 41 of the energy output device 10 determines whether or not the output waveform recognition section 41 receives an active control start signal from the active endoscope control section 14 or the active treatment instrument control section 17, and upon determining that it received the active control start signal, the output waveform recognition section 41 proceeds to step S33. When the output waveform recognition section 41 does not receive the active control start signal, the output waveform recognition section 41 proceeds to step S35.
In step S33, the output waveform recognition section 41 of the energy output device 10 starts timing control of energy output at the time of output of an unstable state waveform, and in step S34, the output waveform recognition section 41 outputs an enabling signal for the active mechanism control to the active endoscope control section 14 or the active treatment instrument control section 17. More specifically, the output waveform recognition section 41 stops energy output for only a predetermined period in the mode in which the unstable state waveform is outputted based on the reception of the active control start signal (step S33), and outputs an enable signal for active mechanism control to the active endoscope control section 14 or the active treatment instrument control section 17 for the predetermined period of stoppage of the output (step S34).
After the lapse of the predetermined period of the output stoppage, the output waveform recognition section 41 starts energy output in step S35, and proceeds to step S24 described in embodiment 3.
Meanwhile, the active endoscope control section 14 or the active treatment instrument control section 17 determines whether or not input of the control instruction of the active mechanism is given from the active endoscope instruction input device 13 or the active treatment instrument instruction input device 16 in step S41 as shown in
In step S42, the active endoscope control section 14 or the active treatment instrument control section 17 determines whether or not it receives the enable signal of the active mechanism control from the output waveform recognition section 41 of the energy output device 10. When receiving the enable signal for active mechanism control, the active endoscope control section 14 or the active treatment instrument control section 17 executes the processing of step S5 described in embodiment 1 during the reception period, and when receiving no enable signal for the active mechanism control, the active endoscope control section 14 or the active treatment instrument control section 17 executes the processing of step S25 described in embodiment 3, and proceeds to step S6 described in embodiment 1.
More specifically, in the present embodiment, when the active endoscope control section 14 or the active treatment instrument control section 17 controls the active mechanism, the active endoscope control section 14 or the active treatment instrument control section 17 outputs an active control start signal to the energy output device 10.
Subsequently, the energy output device 10 stops output of the energy of the unstable state waveform for a predetermined period (for example, time required by control of the active endoscope control section 14 or the active treatment instrument control section 17 is required) during output of the energy of an unstable state waveform based on the active control start signal.
The time required for one command control of the active endoscope control section 14 or the active treatment instrument control section 17 is in the order of ns or μs, and therefore, even if the energy output is stopped for this time period, energy treatment is not influenced.
As described above, in the present embodiment, as in embodiment 3, the output waveform recognition section 41 analyzes/recognizes the energy output, and controls the timing of the energy output based on the active control start signal, whereby, control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 can be performed reliably and stably without receiving the influence of the energy output device 10. Therefore, the present embodiment has the effect of being capable of enhancing noise resistance in the energy treatment easily at low cost.
Embodiment 5 is substantially the same as embodiment 1, and therefore, only the different point will be described. The same components are assigned with the same reference numerals and description thereof will be omitted.
As shown in
In the present embodiment, the active mechanism control device 5 detects the instruction signal from the active endoscope instruction input device 13 or the active treatment instrument instruction input device 16 in the active endoscope control section 14 or the active treatment instrument control section 17 in step S51 as shown in
When the control instruction for the active mechanism is given, the waveform monitor section 50 of the active mechanism control device 5 determines whether or not the energy output is executed from the energy output device 10 in step S52. When the energy output is executed, the waveform monitor section 50 monitors the energy output waveform in step S53, and analyzes the monitored energy output waveform to determine the waveform state (a stable state waveform or an unstable state waveform) of the output waveform in step S54.
Subsequently, based on the energy output state in the waveform monitor section 50, the active mechanism control device 5 executes the processing of steps S5 to S6 described in embodiment 1.
In the present embodiment, upon determining that the state waveform of the output waveform is an unstable state waveform in step S54, the active mechanism control device 5 disables the active mechanism control in step S55 and returns to step S51.
As above, in the present embodiment, as in embodiment 1, control of the active mechanism of the active endoscope 2 or the active treatment instrument 3 can be performed reliably and stably without receiving the influence of the energy output device 10, and therefore, the present embodiment has the effect of being capable of enhancing noise resistance in energy treatment easily at low cost.
The present invention is not limited to the aforementioned embodiments, and various changes, modifications and the like can be made in the range without changing the gist of the present invention.
