Description

Technical Field

[0001] The invention relates to the technical field of laser treatment handpieces, and in particular to a scanning handpiece with a TEC cooling component. Background Art

[0002] Laser therapy technology is a medical method that uses the special physical properties of lasers to precisely operate and treat biological tissues. It is used in dermatology to remove tattoos, scars, hemangiomas, capillary dilation, acne, and can also be used for wrinkle removal and skin rejuvenation. In some treatments, laser scanning technology is used to improve the safety, accuracy and patient comfort of the treatment, while ensuring the maximum treatment effect. Existing laser scanning technology is usually implemented by adding a scanning galvanometer and a motor to the handpiece to form a scanning system. Although scanning technology reduces the risk of thermal damage by quickly moving the laser light spot to avoid staying at a certain point for too long, in order to further protect the skin surface, reduce pain and improve the comfort of treatment, existing technologies will use some cooling methods to reduce the epidermal temperature. The most common cooling methods are described below:

[0003] 1. Cold air cooling method: Use a separate cooling device (such as a cold air meter) to blow cold air of about -10℃ on the skin surface to quickly dissipate heat through large air volume. However, this method has limitations and cannot be applied to sensitive areas such as ears and noses. It also requires a separate device, which increases the investment of manpower and material resources.

[0004] 2. Precooling and cold compress: Before treatment, using ice packs or cold compresses to precool the skin can simply and effectively lower the skin temperature and reduce the thermal effect during treatment. However, the cooling effect of this method is difficult to accurately control and the duration is limited;

[0005] 3. Condensing agent spray cooling: It can quickly cool the skin surface, but it may cause discomfort and even require auxiliary drugs to relieve the discomfort.

[0076] The TEC cooling sheet 206 is located between the hot end water cooling head 204 and the cold end cooling sheet 205. The hot surface of the TEC cooling sheet 206 is fixed to the hot end water cooling head 204 by thermal conductive adhesive, and the cold surface of the TEC cooling sheet 206 is fixed to the cold end cooling sheet 205 by thermal conductive adhesive. The hot end water cooling head 204 is connected to the water circuit of the whole machine through the water outlet pipe 303 and the water inlet pipe 302 to form a water circulation cooling system. A temperature sensor 406 is provided at the end of the cold end cooling sheet 205.

[0077] In order to facilitate installation and removal of the cooling head 202, the installation and removal structure 4 of this embodiment includes:

[0078] Cooling head mounting 403;

[0079] A cooling head 202 mounted on the end of a cooling head mounting member 403 by means of a cooling head mounting fixing pin 401; and

[0080] With respect to the fixing screw 404 at one end of the cooling head 202 , an elastic gasket 405 is installed between the fixing screw 404 and the cooling head mounting member 403 .

[0081] Among them, the cooling head mounting member 403 of this embodiment cooperates with the cooling head mounting fixing pin 401 to open a cooling head mounting inlet 40302 at one end, and a cooling head fixing groove 40303 is connected to the cooling head mounting inlet 40302;

The cooling head anti-horizontal rotation limit pin 402 is connected to the part of the cooling head 202 embedded in the cooling head mounting part 403.

[0083] The installation process of the scanning handpiece of this embodiment is as follows: first, the reflector 109 is glued and fixed on the handpiece light inlet tube 102, and then the handpiece light inlet tube 102, the X-axis scanning galvanometer and motor 105, and the Y-axis scanning galvanometer and motor 106 are respectively connected to the scanning handpiece mounting base 1 by screws; then the cooling head anti-horizontal rotation limit pin 402 is inserted into the cooling head limit groove 40301 of the cooling head mounting part 403 to prevent the cooling head 202 from rotating horizontally after installation; the cooling head mounting part 403 is fixed below the cold end cooling plate 205 by using the fixing screws 404 and the elastic gasket 405, and at the same time, an appropriate pre-tightening force is ensured so that the cooling head mounting part 403 can have a certain displacement under the action of external force, and the displacement is reflected in the vertical direction of the cooling head limit groove 40301, and the temperature sensor 406 is fixed below the cold end cooling plate 205.

[0084] Then install the cooling head installation fixing pin 401 onto the cooling head 202, align it with the cooling head installation entrance 40302 and then rotate it upward into the cooling head fixing groove 40303. The principle of the installation and fixing process is that the external force applied during the rotation process will first compress the elastic gasket 405, and then the elastic gasket 405 will pop up and tighten the cooling head 202 when it is rotated into the cooling head fixing groove 40303.

[0085] The cold surface of the TEC cooling plate 206 and the cold end cooling plate 205, and the hot surface and the hot end water cooling head 204 are fixed by thermal conductive glue respectively, and then fixed to the cooling system shell 203 as a whole by screws, and then the TEC cooling component 2 is assembled as a whole to the TEC cooling component connecting base 201.

[0086] When disassembling the cooling head 202 of the present embodiment, it is only necessary to rotate it in the corresponding horizontal direction for a certain angle and then remove it downward.

[0087] The temperature sensor 406 of this embodiment is generally used to monitor the temperature of the detachable cooling head 202, and to control the cooling efficiency of the TEC cooling sheet 206 in real time according to the feedback temperature, so as to realize real-time control of the temperature of the cooling head 202, accurately control the temperature during the treatment process, and cool in real time as the treatment area moves. After the treatment, the cooling head 202 can be conveniently disassembled for cleaning and disinfection.

[0088] See also Figure 8 As shown, as an extended implementation method, the control system of the scanning handpiece of the TEC cooling component of this embodiment includes: a central processing unit, a light output system, a temperature monitoring system, a TEC cooling system and a water circulation system; wherein the central processing unit controls the light output of the light output system according to the set light output parameters; the TEC cooling system, the TEC cooling system realizes refrigeration operation according to the output current of the central processing unit; the water circulation system, the water circulation system realizes the adjustment of water flow rate according to the output current of the central processing unit, and the temperature monitoring system includes an infrared temperature measuring probe A407, a contact probe B408 and a temperature monitoring unit.

[0089] The specific working process is as follows: the central processing unit controls the light emitting system to emit light according to the set light emitting parameters, and the central processing unit also controls the basic current signal of the TEC cooling system to realize cooling work; the infrared temperature measuring probe A407 is used to test the temperature of the skin at different times, and the contact probe B408 is used to test the real-time temperature of the alloy probe. The infrared temperature measuring probe A407 and the contact probe B408 send the obtained temperature signals to the temperature monitoring unit, and the temperature monitoring unit sends the actual temperature signal to the central processing unit. The central processing unit adjusts the working current of the TEC cooling system again according to the feedback signal of the temperature monitoring system to adjust the cooling temperature of the alloy cooling head.
