Description

Technical Field

[0002] Focused ultrasound uses the principles of ultrasound directionality, tissue penetration and focusing to gather ultrasound waves that penetrate tissues and release a large amount of energy in the focused area, with good penetration and positioning. Existing focused ultrasound treatment handles can accurately position ultrasound energy in target treatment tissues, such as the dermis, subcutaneous fat layer, SMAS layer, etc., to achieve lifting, firming, skin rejuvenation and fat reduction effects.

[0003] Some current ultrasonic therapeutic devices are usually composed of a handle and a treatment head, wherein the transducer in the treatment head can emit ultrasonic waves. The focus of the transducer of the existing ultrasonic therapeutic device is generally in the form of a straight tube, that is, the handle and the treatment head are arranged in a straight tube in appearance, so as to facilitate the setting of the driving device of the transducer inside the handle. However, there are still some ultrasonic therapeutic devices on the market, which form a certain angle between the handle and the treatment head in appearance, such as a right angle setting, in order to meet the needs of ergonomic design. However, it becomes very difficult to adjust the focal length of the transducer in this type of ultrasonic therapeutic device, so it is necessary to replace the treatment handles of different focal lengths for alternating use, which brings great trouble to medical staff and the entire treatment process.

[0023] See also Figure 1As shown, a variable focus ultrasonic treatment handle of the utility model comprises: a housing 1, a driving device 2 and a transducer 3. The housing 1 is provided with a mounting cavity 10, and the driving device 2 and the transducer 3 are both arranged in the housing 1. The driving device 2 comprises a motor 21 and a connecting rod mechanism 22. The output shaft of the motor 21 is rotatably connected to the input end of the connecting rod mechanism 22, and the output end of the connecting rod mechanism 22 is movably connected to the transducer 3. The motor 21 is a linear motor capable of outputting linear motion. The output shaft of the motor 21 is arranged along the X-axis direction, thereby determining that the motor 21 outputs a linear motion along the X-axis direction. The central axis of the transducer 3 is arranged along the Y-axis direction, thereby determining that the longitudinal adjustment of the focus of the transducer 3 is an adjustment in which the focus moves along the Y-axis direction. The motor 21 drives the output shaft to perform X-axis linear motion to push the input end of the connecting rod mechanism 22 to move, so that the output end of the connecting rod mechanism 22 pushes the transducer 3 to perform Y-axis linear motion, thereby realizing the longitudinal adjustment of the focus of the transducer 3.

[0024] Specifically, the connecting rod mechanism 22 includes a first connecting rod 221 and a second connecting rod 222, one end of the first connecting rod 221 is rotatably connected to the output shaft of the motor 21, the other end of the first connecting rod 221 is rotatably connected to one end of the second connecting rod 222, the other end of the second connecting rod 222 is movably connected to the transducer 3, and a hinge hole is provided on the second connecting rod 222, and the second connecting rod 222 is hinged to the inner wall of the housing 1 through a rotating shaft 223 passing through the hinge hole. The motor 21 drives the output shaft to perform X-axis linear motion, pushes the first connecting rod 221 to swing, and the first connecting rod 221 pushes the second connecting rod 222 to swing around the rotating shaft 223, so that the second connecting rod 222 pushes the transducer 3 to perform Y-axis linear motion, thereby realizing the longitudinal adjustment of the focus of the transducer 3.

[0025] Preferably, the connection points at both ends of the second connecting rod 222 and the three-point line of the hinge point of the second connecting rod 222 form a triangle, so that the X-axis linear motion output by the output shaft driven by the motor 21 can be smoothly converted into the Y-axis linear motion of the transducer 3. It is also beneficial to optimize the spatial layout of the connecting rod mechanism 22 to adapt to the narrow space and special structural layout in the housing 1.

A guide sleeve 15 is arranged on the inner side wall of the housing 1. The guide column 33 is inserted into the guide sleeve 15. The guide column 33 can move freely in the Y-axis direction along the guide sleeve 15. A reset spring 4 is also sleeved on the guide column 33. The two ends of the reset spring 4 are respectively in contact with the guide sleeve 15 and the limit portion 34. The return spring 4 is compressed and generates an elastic force when the second connecting rod 22 pushes the transducer 3 to move downward along the Y-axis direction. When the second connecting rod 22 moves upward, the elastic force always pushes the transducer 3 toward the second connecting rod 22, which helps to make the top end of the transducer 3 reliably contact and abut with the output end of the second connecting rod 22, thereby achieving the purpose of upward movement of the transducer 3 along the Y-axis direction and realizing the longitudinal reciprocating adjustment of the transducer focus.

[0028] The contact position between the guide post 33 and the output end of the connecting rod mechanism 22 , that is, the contact position between the pusher 224 and the guide post 33 , is provided with an arc groove to fit the swing trajectory of the output end provided on the second connecting rod 22 .

The support body 5 is provided with a guide hole 51 along the Y-axis direction, and the output shaft of the motor 21 is sealed and penetrated in the guide hole 51.

[0031] A pressure balancing device 6 is also provided in the accommodating cavity to balance the pressure fluctuations in the accommodating cavity caused by the movement of the transducer 3. The pressure balancing device 6 includes a retractable airbag 61, the side wall of which is in the shape of a bellows as a whole, and the retractable airbag 61 is provided with a connection port, and a mounting platform 62 is provided on the inner side wall of the housing 1. The connection port is sealed and sleeved on the mounting platform 62, and a vent hole 63 is provided in the mounting platform 62 to connect the inner cavity of the retractable airbag 61 with the outside.
