Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an ultrasonic treatment head and an ultrasonic treatment device. Background Art

[0002] Ultrasound is a high-frequency mechanical wave that has the characteristics of focusability, tissue penetration and energy deposition. An ultrasonic treatment device is a device that uses a focused ultrasonic transducer to focus ultrasound on a biological body, and produces thermal effects, cavitation effects and mechanical effects through the interaction between ultrasound and biological tissues to exert corresponding biological effects. It includes an ultrasonic treatment handle and a treatment head. The treatment head is detachably connected to the handle, and the transducer in the treatment head can emit ultrasound to act on the skin.

[0003] The invention patent application with application number CN201410794037.6 discloses an ultrasonic treatment handle, in which the motor drives the transducer to perform at least one or more combined movements of transverse linear scanning, longitudinal linear scanning and transverse plane scanning to achieve multiple scanning output modes, which can be adapted to rapid treatment of various parts, but the specific driving structure is not disclosed.

[0004] The utility model patent with application number CN201520088495.8 discloses a focused ultrasonic beauty instrument, which is equipped with a rotating motor. Under the control of the rotating motor and the moving motor, the precise distribution of the focused energy points of the focused piezoelectric ceramic sheet on the skin action surface can be accurately controlled. Through a single operation, multiple evenly arranged high-temperature points arranged in a surface can be emitted, and the lateral and longitudinal action positions between points can be accurately controlled.

[0005] Although the utility model patent with application number CN201520088495.8 solves the problem of achieving planar treatment in a single operation, it still has the following problems:

[0006] 1. The connecting rod lacks guidance when driving the rotating rod to make linear and rotational motion, which makes the ceramic piece unstable. During the movement, the ceramic piece will shake slightly, which will change the point of action of the ultrasound and affect the treatment effect.

[0007] 2. The gas in the seals on both sides of the rotating rod cannot flow to each other, so when the linear motion occurs, the gas pressure in the seals will produce a certain resistance to the linear motion, which is not conducive to reciprocating motion;

[0008] 3. When the treatment head is removed from the handle, there is no limit on the connecting rod, ceramic plate and rotating rod, so the connecting rod can be flexibly extended into or out of the treatment head shell, and the ceramic plate and the rotating rod can also move freely in the treatment head. Improper protection may easily cause damage to the transmission structure and the ceramic plate. Summary of the invention

[0044] One end of the connecting rod 11 located in the first housing 10 is a mounting end 111, and the transducer assembly 12 is arranged on the mounting end 111. A first sealing member 14 is arranged between the first mounting seat 101 and the mounting end 111, and a second sealing member 15 is arranged between the second mounting seat 102 and the mounting end 111.

[0047] In the ultrasonic treatment head, when the connecting rod 11 drives the transducer assembly 12 to perform linear motion and rotational motion, the connecting rod 11 slides along the guide rod 13. The connecting rod 11 is guided by the guide rod 13, which can prevent the installation end 111 of the connecting rod 11 from shaking, so that the transducer assembly 12 can move more stably, thereby ensuring the treatment effect; the first seal 14 and the second seal 15 can effectively prevent the liquid in the first shell 10 from leaking from the active gap of the connecting rod 11 and prevent leakage of electricity.

Specifically, Figure 6 and Figure 7 As shown, when the ultrasonic treatment head is removed, the mounting end 111 is pushed to the rightmost end by the reset member 17, so that the second connector 19 of the connecting end 113 abuts against the first mounting seat 101, preventing the connecting rod 11 and the transducer assembly 12 from moving at will, thereby playing a protective role.

[0051] In this embodiment, the reset member 17 is a reset spring, which is sleeved on the outside of the guide rod 13. Specifically, the reset spring can effectively push the mounting end 111 to reset, with a simple structure and high reliability; in other embodiments, other methods such as magnetic attraction can also be used to achieve the same reset effect.
