Technical Field

[0002] The existing positioning treatment head mechanism controls the dwell position and dwell time of the transducer through a stepping motor or other methods, which can also achieve a relatively good control effect to a certain extent.

[0003] However, the commonly used treatment head control mechanism has the following problems: it cannot provide real-time feedback of the transducer's position information, cannot provide timely feedback of the transducer's real-time position information when the transducer or transmission mechanism encounters resistance and cannot move, or when the stepper motor cannot rotate normally for some reason, which may cause the transducer to implement an overdose of treatment at one position. Therefore, we propose a mechanism that can accurately position the treatment head. Utility Model Content

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] A precisely positioned ultrasonic treatment handle comprises a handle housing 1, a connecting mechanism, a detecting mechanism and a treatment head 3, wherein the connecting mechanism is arranged in the handle housing 1, the connecting mechanism comprises a motor screw 22, a tenon 23, a push rod 24 and a first strong magnet 25, and the detecting mechanism comprises a sliding rheostat 26, the sliding rheostat 26 is arranged on the side of a stepping motor 21 and is connected with the tenon 23 in cooperation;

[0027] One end of the tenon 23 is fixed to the motor screw 22 via an internal thread, and the other end is connected to the sliding rheostat 26 via a slot. One end of the push rod 24 cooperates with the tenon 23, and the other end is provided with a first strong magnet 25.

[0028] The treatment head 3 includes a second strong magnet 32, a bellows 33 and a transducer 34. A partition 5 is provided between the second strong magnet 32 ​​and the first strong magnet 25 on the push rod 24, and the two magnets are in contact through the perforations on the partition 5. After the two strong magnets are connected, the bellows 33 is pushed to move, thereby driving the transducer 34 to move.

[0029] The treatment head 3 is detachably matched with the handle shell 1 and is fixed to the handle shell 1 by a lock 4.

[0030] When in use, the control system controls the rotation of the stepper motor 21, and converts the rotation of the motor screw 22 into the movement of the push rod 24 through the tenon 23. The first strong magnet 25 on the other end of the push rod 24 is connected to the second strong magnet 32 ​​in the treatment head 3; the push rod 24 drives the transducer 34 and the middle plug of the sliding rheostat 26 to move synchronously through the first strong magnet 25 and the second strong magnet 32. During the movement, the resistance value between the middle tap and any end of the sliding rheostat 26 is detected in real time; by measuring the resistance value of the middle tap of the sliding rheostat and any end thereof, the position of the middle plug can be accurately reflected, and then the position of the transducer 34 can be fed back to avoid excessive treatment of the transducer at one position.
