For example, when the left and right treatment elements 28A and 28B are rocked in the same phase as in the example of the treatment mode shown in FIG. It is determined whether or not it is at the position (the front end position in the example shown). Then, if one of the left and right treatment elements 28A, 28B is at a different position from the other, one or both of them are swung to be positioned at the same starting position (step S102). If the left and right treatment elements 28A, 28B are at the starting position, a treatment mode is executed in which the left and right treatment elements 28A, 28B are rocked in the same phase (step S101). Further, even during execution of the same treatment mode, the swing positions of the left and right treatment elements 28A and 28B may be detected by the left and right detectors 29A and 29B, and appropriate correction may be made so that they swing in the same phase. .

In the example of FIG. 4(c) showing a modified example of the treatment mode, the right and left treatment elements 28A and 28B are oscillated so that their phases are different by 180 degrees, that is, in opposite phases. In this example as well, in step S100, it is determined whether or not the left and right treatment elements 28A and 28B are at starting positions that are 180 degrees out of phase (in the example shown, the left treatment element 28A is at the front end and the right treatment element 28B is at the rear end). determine whether Then, if the angle difference (phase difference) between the left and right treatment elements 28A and 28B is not 180 degrees, one or both of them are swung to position them so that they have an angle difference of 180 degrees (step S102). If the left and right treatment elements 28A, 28B are at the start position, a treatment mode is executed in which the left and right treatment elements 28A, 28B are rocked in opposite phases (step S101). Further, even during execution of the same treatment mode, the swing positions of the left and right treatment elements 28A and 28B may be detected by the left and right detectors 29A and 29B, and appropriate correction may be made so that they swing in opposite phases. .
Further, the rocking mode of the left and right treatment elements 28A and 28B in the treatment mode executed by the control unit 10 is not limited to the mode described above. For example, the left and right treatment elements 28A and 28B may be oscillated with a phase difference of an arbitrary angle other than 180 degrees, such as 90 degrees. Also, the left and right treatment elements 28A and 28B may be rotated at mutually different rotation speeds (periods) or may be rotated in opposite directions, and other various rocking modes may be employed. Such various rocking modes may be set in advance according to the treatment site, or may be arbitrarily selectable.

FIGS. 11A to 11D are diagrams schematically showing an example of a treatment element unit 20O according to the thirteenth modification.
In this modification, the rocking mechanism (left rocking mechanism 24A and right rocking mechanism 24B) 24I is interlocked with the upper treatment elements (left treatment element 28A and right treatment element 28B) 28C to move the lower treatment element (lower left). The side treatment elements 38A and the lower right treatment elements 38B) and 38D are configured to swing. In this modification, the rocking mechanism 24I includes a treatment element holding portion 27A provided with a cam receiving portion 27a that rotatably receives a disk-shaped eccentric cam 26 that is non-rotatably fixed to the eccentric shaft 25. and a lower treatment element holding part 37 rotatably connected to the treatment element holding part 27A. In this modification, the axial direction of the eccentric shaft 25 is generally the width direction of the body. In this modification, the treatment element holding part 27A is elongated substantially in the longitudinal direction of the body, and is configured such that an upper treatment element 28C is attached to an attachment part projecting forward from the upper end thereof. . A guide groove 27b is provided on the lower side of the cam receiving portion 27a of the treatment element holding portion 27A so as to extend in the longitudinal direction of the treatment element holding portion 27A. A restriction projection 24a similar to that described above is inserted into the guide groove 27b.

Approximately the same as in the first modification, the upper treatment element 28C rotates the disk-shaped eccentric cam 26 when the motor 22 is driven, thereby moving in an arc while being restricted by the restriction protrusion 24a. In conjunction with the treatment element holding portion 27A, it swings up and down so as to draw an ellipse with a major axis. In this modified example, the upper treatment element 28C swings so as to draw an ellipse with a major axis vertically, with the upper side being the rear side of the lower side.
The lower treatment element holding part 37 is rotatably connected to the lower end of the treatment element holding part 27A by a connecting shaft 27c. Similar to the treatment element holding part 27A, the lower treatment element holding part 37 has a plate shape whose thickness direction is the axial direction of the eccentric shaft 25, and extends obliquely forward and downward from the upper end connected to the connection shaft 27c. It is provided so as to extend to the side. The lower treatment element holding portion 37 is provided with a guide groove 37a into which a pin-shaped restricting projection 24b fixedly provided on the support portion 21 side is inserted. The guide groove 37a is provided so as to extend generally in the body thickness direction (front-rear direction). The lower treatment element holding part 37 is regulated by the regulating projection 24b inserted into the guide groove 37a, and interlocks with the swinging motion of the treatment element holding part 27A accompanied by the rotation of the disk-shaped eccentric cam 26 described above. It swings so as to interlock with the connecting shaft 27c that swings so as to draw an (ellipse). Thus, the lower treatment element holding part 37 swings, and the lower treatment element 38D provided at the front end part swings so as to draw a circle (ellipse).

In this modified example, the upper treatment element 28C and the lower treatment element 38D are configured to oscillate in a circle with a phase difference (in the figure, a phase difference of approximately 180 degrees). . The upper treatment element 28C and the lower treatment element 38D are configured to swing toward and away from each other. In other words, when the motor 22 is driven to rotate in one direction, the upper treatment element 28C swings in a circular motion passing through the front end position, the lower end position, the rear end position and the upper end position in order, and then swings downward. The side treatment element 38D swings in a circular motion passing through the rear end position, the upper end position, the front end position and the lower end position in order. When the motor 22 is driven to rotate in the other direction, the upper treatment element 28C swings in a circular motion passing through the front end position, the upper end position, the rear end position and the lower end position in order, and then swings downward. The side treatment element 38D oscillates in a circle so as to pass through the rear end position, the lower end position, the front end position and the upper end position in order.

The mutually different configurations described in each of the above examples may be rearranged or combined for application.
In the above examples, the upper treatment elements 28, 28A to 28H and the lower treatment elements 38, 38A to 38D are oscillated periodically along a predetermined circumference. One or both of the elements 28, 28A to 28H and the lower treatment elements 38, 38A to 38D may be configured to swing substantially linearly by a crank mechanism or the like.
