Abstract

Disclosed is a handpiece allowing for the forward-backward and vertical movement of an ultrasound catheter. The handpiece is configured such that an ultrasound catheter installed in the handpiece can be selectively moved back and forth by a certain distance in a straight line in a front-rear direction so that the ultrasound catheter can perform an ultrasound procedure at uniform intervals across a large area for the procedure. In addition, the convenience of using the handpiece is increased because the handpiece is configured such that the subcutaneous depth, at which the ultrasound generated from the ultrasound catheter installed in the handpiece is to be focused, can be freely changed, without having to exchange cartridges containing ultrasound catheters having different focal distances.

Description

Handpiece that can move back and forth and up and down ultrasonic wave

The present invention relates to a handpiece, and more particularly, it is configured to move so that the ultrasonic wave is installed in the handpiece to selectively reciprocate linearly by a predetermined interval in the front and rear direction at a uniform interval over a large surgical area without moving the handpiece It is not only configured to perform the ultrasound procedure, but also easy to use because the subcutaneous depth to focus the ultrasound generated from the ultrasound ceramic can be changed freely without replacing other cartridges in which the ultrasound ceramics with different focal lengths are built. A handpiece capable of moving back and forth and up and down of the increased ultrasonic wave.

In general, when converging the sunlight in one place, heat is generated in the focusing area, and concentrating high-intensity ultrasonic energy in one place generates high heat of about 65 to 100 in the focusing area.

A device for burning (coagulating necrosis) certain subcutaneous tissues such as intratumoral tumors by using heat generated by ultrasound focusing is a high-intensity focused ultrasound surgery device, and using heat generated by ultrasound focusing, A device that has been miniaturized to induce degeneration and regeneration to produce skin beauty or unshaping effects such as wrinkle improvement is a high intensity focused ultrasound device known as "Ulthera."

The high-intensity focused ultrasound apparatus includes a main body for supplying power for generating an ultrasonic wave and generating a control signal according to an operator's manipulation, and a connecting cable detachably coupled to the main body and covering a power line and a control signal transmission line. It comprises a handpiece which is connected to the end of the connecting cable and provided with an ultrasonic ceramic for generating ultrasonic waves.

However, in the case of the conventional handpiece for high-intensity focused ultrasound apparatus having the above-described configuration, the ultrasonic ceramic does not move. Therefore, in order to perform the ultrasonic treatment over a large area, the operator lifts the handpiece body and moves it slightly back and forth. Since the ultrasound procedure is very cumbersome and the interval in the front and rear directions cannot be maintained constantly, there is a problem that the procedure is inevitably made over the entire treatment area.

In addition, in the case of the conventional handpiece for high-intensity focused ultrasound apparatus, the ultrasonic ceramic is fixed in height, that is, the position in the vertical direction, and thus the subcutaneous depth at which the ultrasound is focused cannot be adjusted, so that the subcutaneous depth at which the ultrasound is focused is changed. In order to achieve this, there was an inconvenience in the procedure of having to replace and replace the other cartridge in which the ultrasound ceramics with different focal lengths were built.

The present invention has been made to solve the above problems, and an object of the present invention is to move the ultrasonic transducer installed in the handpiece to reciprocate linearly at regular intervals in the front and rear direction to be uniform over a large surgical area without moving the handpiece It is not only configured to perform ultrasonic treatment at intervals, but also to freely change the subcutaneous depth at which ultrasonic waves generated in ultrasonic ceramics can be focused even without replacing another cartridge in which ultrasonic ceramics with different focal lengths are built.

That is, when the cylinder arm 622 is extended or contracted, the coupling protrusion 631 is moved left and right in the slide groove 623a of the connecting block to compensate for the gap so that the vertical space adjusting frame 610 is not bent. To do.

It will now be described the operation and action / effect of the handpiece capable of moving back and forth and up and down the ultrasonic transducer according to the present invention configured as described above.

First, in order to perform ultrasound through the handpiece according to the present invention, the operator once closes the bottom portion (the upper and lower space adjusting frame) of the handpiece main body 100 to the skin tissue S of the patient who is the subject. Then, the ultrasonic wave 10 is generated by the operation of the operation unit 500 to perform ultrasonic waves on the skin tissue of the patient.

Here, by operating the operation unit 500, by controlling the rotation direction of the step motor 4100, the front and rear transfer screw 420 is operated to rotate forward or reverse. Then, as shown in Figures 3 and 4, the front and rear conveying pipe 430 coupled to the support 300 is selectively moved forward or backward and the ultrasonic transducer 10 coupled to the lower support 300 is selectively moved forward or You will reverse.

Therefore, since the support 300 is selectively stepped forward and backward through the front and rear transfer means 400, the ultrasonic ceramic 100 installed at the lower end of the support 300 is also stepped forward and backward to move the handpiece main body 100. There is an advantage in that the ultrasonic treatment can be performed at uniform intervals over a wide treatment area in the front and rear direction without moving.

And, as shown in Figure 5 by operating the operation unit 500 to extend or contract the cylinder 620 to adjust the vertical height of the ultrasonic ceramic 10 and the skin tissue (S). That is, as shown in FIG. 6, when the cylinder 620 is extended, the upper and lower intervals of the ultrasonic ceramics 10 and the skin tissue become high, and the subcutaneous depth at which the ultrasonic waves generated by the ultrasonic ceramics 10 are focused is shallow, and FIG. 7. As shown in FIG. 5, when the cylinder 620 is contracted, the upper and lower intervals of the ultrasonic conductor 10 and the skin tissue S are lowered to deepen the subcutaneous depth at which the ultrasonic waves generated by the ultrasonic conductor 10 are focused. Therefore, the vertical height of the ultrasonic ceramics 10 is adjusted through the vertical height adjusting means 600 so that ultrasonic waves generated by the ultrasonic ceramics 10 are focused even if the cartridges having different focal lengths are not replaced. There is an advantage that the depth to be avoided can be changed freely.

While the invention has been shown and described in connection with specific embodiments, it will be understood that various modifications and variations can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone can grow up easily.

The present invention is a skin disease, specific examples include vascular diseases such as flaming nevus, capillary dilatation, arachnoid hemangioma, senile hemangioma, and pigmented skin diseases such as moles, otamos, tattoos, melanin pigment spots, freckles, and surpluses. And it can be usefully used in the treatment of gwanjongjong, angiofibromatosis, pigmented birthmark, epidermal nevus and the like.
