Abstract

A treatment system includes: a treatment instrument for cutting living tissue in a liquid; and a controller for performing control, prior to cutting the living tissue with the treatment instrument, to suppress reduced visibility of a treatment area due to turbidity in the liquid caused by the cutting of the living tissue based on preparation information regarding cutting preparation for the treatment instrument.

Claims (49)

1 . A treatment system comprising: a treatment instrument extending in a longitudinal axis direction, the treatment instrument being configured to cut living tissue in a liquid; a controller configured to perform control, prior to cutting the living tissue with the treatment instrument, to suppress reduced visibility of a treatment area due to turbidity in the liquid caused by the cutting of the living tissue based on preparation information regarding cutting preparation for the treatment instrument; and wherein the treatment instrument includes a sensor configured to detect movement in three axial directions and rotation around each axis, the three axial directions being orthogonal to one another and including an axis parallel to the longitudinal axis, and the controller is configured to acquire, as the preparation information, information regarding the movement in each of the three axial directions and the rotation detected by the sensor.

2 . The treatment system according to claim 1 , wherein the controller is configured to acquire the preparation information.

3 . The treatment system according to claim 1 , wherein the controller is configured to calculate a movement amount of the treatment instrument based on the information regarding the movement and the rotation and perform the control to suppress reduced visibility of the treatment area based on the calculated movement amount.

4 . The treatment system according to claim 2 , further comprising

an imager configured to capture an image of the treatment instrument and a vicinity of the treatment instrument, wherein

the controller is configured to acquire, as the preparation information, image data on the living tissue and a vicinity of a distal end of the treatment instrument captured by the imager.

5 . The treatment system according to claim 4 , wherein

the controller is configured to calculate a movement amount of the treatment instrument based on the image data to perform the control to suppress reduced visibility of the treatment area based on the calculated movement amount.

6 . The treatment system according to claim 2 further comprising:

a display configured to display an image of the treatment instrument and a vicinity of the treatment instrument; and

a line-of-sight detector configured to detect a line-of-sight of a user of the treatment instrument with respect to the display, wherein

the controller is configured to acquire, as the preparation information, line-of-sight information regarding the line-of-sight of the user detected by the line-of-sight detector.

7 . The treatment system according to claim 6 , wherein

the controller is configured to calculate a movement amount of the treatment instrument based on the line-of-sight information to perform the control to suppress reduced visibility of the treatment area based on the calculated movement amount.

8 . The treatment system according to claim 7 , further comprising

a foot switch configured to be pushed in at least two stages and output a signal different in each of the at least two stages, wherein

the controller is configured to acquire, as the preparation information, the signal output from the foot switch.

9 . The treatment system according to claim 8 , wherein

the controller is configured to perform the control to suppress reduced visibility of the treatment area based on the signal output from the foot switch.

10 . The treatment system according to claim 1 , further comprising:

an imager configured to capture an image of the treatment instrument and a vicinity of the treatment instrument;

an endoscope controller configured to process the image captured by the imager; and

a display configured to display the image processed by the endoscope controller, wherein

the controller is configured to perform control to reduce deterioration of a display image to be displayed on the display as the control to suppress reduced visibility of the treatment area.

11 . The treatment system according to claim 10 , wherein

the controller is configured to perform control to enhance an edge of a subject in the image captured by the imager as the control to reduce deterioration of the display image.

12 . The treatment system according to claim 1 , further comprising

a treatment instrument controller configured to control an operation of the treatment instrument, wherein

the controller is configured to perform control to reduce the turbidity in the liquid as the control to suppress reduced visibility of the treatment area.

13 . The treatment system according to claim 12 , wherein

the controller is configured to perform control to reduce driving power for the treatment instrument as the control to reduce the turbidity in the liquid.

14 . The treatment system according to claim 12 , wherein

the controller is configured to perform control to increase driving power for the treatment instrument as the control to reduce the turbidity in the liquid.

15 . The treatment system according to claim 1 , further comprising

a perfusion device configured to control perfusion of the liquid, wherein

the controller is configured to perform control to adjust perfusion of the liquid by the perfusion device to reduce the turbidity in the liquid as the control to suppress reduced visibility of the treatment area.

16 . The treatment system according to claim 15 , wherein

the controller is configured to perform control to increase a supply speed of the liquid as the control to reduce the turbidity in the liquid.

17 . The treatment system according to claim 16 , wherein

the perfusion device is configured to suction the liquid, and

the controller is configured to perform control to increase a suction amount of the liquid.

18 . The treatment system according to claim 1 , wherein

the treatment instrument is an ultrasound treatment instrument.

19 . The treatment system according to claim 1 , wherein

the turbidity in the liquid is caused by bone powder generated when a bone is cut by hammering with ultrasonic vibration.

20 . The treatment system according to claim 1 , wherein

the turbidity in the liquid is due to white particles.

21 . A control device comprising a controller configured to, prior to cutting living tissue in a liquid using a treatment instrument that extends in a longitudinal axis direction, perform control to suppress reduced visibility of a treatment area due to turbidity in the liquid caused by the cutting of the living tissue based on preparation information regarding cutting preparation for the treatment instrument; and wherein the treatment instrument includes a sensor configured to detect movement in three axial directions and rotation around each axis, the three axial directions being orthogonal to one another and including an axis parallel to the longitudinal axis, and the controller is configured to acquire, as the preparation information, information regarding the movement in each of the three axial directions and the rotation detected by the sensor.

22 . A method of operating a treatment system, the treatment system including a treatment instrument and a controller, the treatment instrument extending in a longitudinal axis direction, the treatment instrument being configured to cut living tissue in a liquid, the method comprising: performing control, by the controller, prior to cutting the living tissue with the treatment instrument, to suppress reduced visibility of a treatment area due to turbidity in the liquid caused by the cutting of the living tissue based on preparation information regarding cutting preparation for the treatment instrument; and wherein the treatment instrument includes a sensor configured to detect movement in three axial directions and rotation around each axis, the three axial directions being orthogonal to one another and including an axis parallel to the longitudinal axis, and the controller is configured to acquire, as the preparation information, information regarding the movement in each of the three axial directions and the rotation detected by the sensor.
