Hand-hold ultrasonic treatment gun

Abstract

The invention discloses a hand-held ultrasonic therapy gun which comprises a handle (4) and a therapy head (24) in which an ultrasonic transducer (21) is provided, wherein, a therapy head motion mechanism that can lead the therapy head to move is connected between the handle and the therapy head. The therapy head motion mechanism comprises a drive unit, a transmission unit that is connected with the drive unit, a fixed sleeve (3) that is connected with the handle and a movable sleeve (2) that is sheathed at the front end of the fixed sleeve and can slide against the fixed sleeve; the movable sleeve is connected with the transmission unit and the therapy head is fixed on the movable sleeve. The hand-held ultrasonic therapy gun can cause the therapy head to move at a constant speed and is simple and compact in structure and convenient in operation.

Description

technical field [0001] The invention belongs to the field of ultrasonic treatment, and relates to a hand-held ultrasonic treatment gun. Background technique [0002] Traditional hand-held ultrasonic therapy guns mostly use manual methods to move the treatment gun to cover the treatment area. Due to human factors during the movement of hands, this type of treatment gun cannot ensure that the ultrasonic energy emitted by the ultrasonic transducer can evenly cover the lesion. It is very likely that the treatment intensity of a certain lesion is too large, and the treatment intensity of a certain area is not enough, which is unpredictable for both patients and doctors. Therefore, in the field of ultrasonic therapy, a treatment gun with a higher degree of automation has been sought to make up for the shortcomings of traditional hand-held treatment guns. [0003] There was a treatment gun in which the transducer could move automatically in the treatment head afterwards, as the pu...

Problems solved by technology

But because this kind of treatment gun is equipped with devices such as drivers and position detectors in the treatment head part, the treatment head is usually relatively large, and has the disadvantages of being heavy and inconvenient to operate; When the transducer moves with the driver, it will drag the cable and move, which will easily lead to disconnection and poor contact during the treatment process; since the treatment head needs to be cooled and coupled in the ultrasonic treatment, the sealing problem of the gun body becomes a big problem , and the treatment head adopts the method of installing the control device and the transducer into the treatment head at the same time, and then performing a waterproof partition. The manufacturing process and material selection of the partition are very demanding, which is obviously unreliable. Once there is leakage, it will cause the drive and other electric control devices to be burned
