[0023] Such as Figures 1-8As shown in the figure, the embodiment of the present invention provides a high-power medical treatment device integrating solid laser and semiconductor laser, including a device box body 1. Inside the device box body 1, a laser 11 is fixedly installed. Below the laser in the device box body 1, a refrigerator 2 is provided.

The main transmission wheel 3041 and the driven transmission wheel 3042 are in transmission cooperation through the transmission chain 3043.

[0024] Further, a heat absorption pipe 22 is connected to the input end of the refrigerator 2. The top end of the heat absorption pipe 22 is connected to a heat absorption cylinder 221, and a heat absorption fan 222 is fixedly installed on the inner wall of the heat absorption cylinder 221. At the top end of the heat absorption cylinder 221, there are a first arc plate 223, a second arc plate 224 and two side plates 225. The first arc plate 223 is located on one side of the laser 11, the second arc plate 224 is located below the laser 11, and the two side plates 225 are respectively located on both sides of the laser 11.

The wind direction turning plate 3011 is rotationally fitted inside the third output pipe 215.

[0025] Further, a laser power supply 12 is fixedly installed on one side surface of the equipment box body 1 above the ventilation mechanism 3, an optical fiber interface 13 is arranged above the laser power supply 12 on one side surface of the equipment box body 1, and a display screen 14 is fixedly installed on the outer top of the equipment box body 1.

[0026] The treatment equipment of the present invention mainly consists of an equipment box body 1, a refrigerator 2, a laser 11, a laser power supply 12 and an optical fiber interface 13. It is controlled by a foot controller outside the equipment box body 1 (not shown in the figure). It is connected to an optical fiber through the optical fiber interface 13. The equipment power is controlled by the internal laser power supply 12, and the corresponding laser is provided outward by the laser 11.

[0027] The laser 11 is a device capable of emitting laser. A large amount of heat will be generated during the operation of the laser 11. When the ambient temperature of the laser 11 is too high (greater than 35 °C), the efficiency of the laser diode will decrease (the life is halved for every 10 °C increase), and the crystal thermal lens effect will intensify. During the use of the laser 11, an external cooling system is required to control the temperature of the laser 11. When the external ambient temperature and humidity are too high and the moisture in the air is saturated, since the surface temperature of the laser 11 is lower than the dew point temperature of the nearby air, the moisture in the air will be condensed and attached to the laser, and condensation water will appear, resulting in dew condensation. The dew condensation phenomenon may not only occur on the outer surface of the laser 11, but also there is a risk of condensation and dew formation in the internal components and optical devices of the laser 11, which will affect the use effect and service life of the equipment.

[0028] The usage steps of the present invention are as follows: After the optical fiber is plugged into the optical fiber interface 13, the device power supply is started, and the medical staff steps on the control to start the device. At this time, the laser 11 inside the device box 1 starts to operate. The laser 11 generates a large amount of heat. When the treatment device is started, the refrigerator 2, the heat absorption fan 222, and the air inlet fan 309 are simultaneously started.

[0029] The air flow control principle of the present invention is as follows: After the refrigerator 2, the heat absorption fan 222, and the air inlet fan 309 are started, the arc-shaped first arc plate 223, the second arc plate 224, and the two side plates 225 can better absorb the heat generated by the laser 11 by the heat absorption fan 222, so that the heat enters the inside of the refrigerator 2 along the path of the heat cylinder 221 - the heat absorption pipe 22. The inside of the refrigerator 2 is composed of an evaporator, a compressor, and a heat exchanger. The gas cooled by the refrigerator 2 is discharged through the output main pipe 21. When the cooled gas follows the path of the first output pipe 211 - the second output pipe 212 - the annular pipe 214 - the third output pipe 215 inside the output main pipe 21, and finally flows along the outer expansion pipe 216 connected to the top of the third output pipe 215 in the direction of the laser 11 and the laser power supply 12 provided at the top of the outer expansion pipe 216 to circulate cold air, it realizes that the heat absorption fan 222 inhales hot air and cools it through the refrigerator 2 to form cold air, and the cold air expands the low temperature through the outer expansion pipe 216, realizing the function of cooling the inside of the device and achieving the effect of cooling the laser.

[0030] During the process of cooling the laser 11, the cold air converted by the refrigerator 2 passes through the water absorption pipe 213 and the annular pipe 214 inside the output main pipe 21 to reduce the water vapor output by the refrigerator 2: The cold air output by the refrigerator 2 first passes through the horizontally arranged first output pipe 211 and then enters the second output pipe 212, and then the cold air enters the annular pipe 214 arranged in a ring. The cold air moves upward and the annular arrangement of the annular pipe 214 makes the water vapor adhere to the inner wall of the annular pipe 214, and finally flows into the bottom of the water absorption pipe 213 provided at the bottom end of the second output pipe 212. The water vapor is adsorbed by the activated carbon 2131 at the bottom of the water absorption pipe 213, improving the dryness of the cold air and avoiding condensation when the cold air output through the outer expansion pipe 216 encounters the laser 11, reducing the impact on the usage effect and service life of the treatment device.

[0031] When starting the treatment device, several blades 3071 on the ventilation mechanism 3 change from the sealed state to the open state. The use effect of the blades 3071 is similar to that of a shutter. When several blades 3071 are in the sealed state, the traction spring 3081 fixedly connected between the bottom ends of the two traction ropes 308 and the inner wall of the air inlet plate frame 306 is always in a stretched state, so that several blades 3071 are in a vertical state, and the wind direction turning plate 3011 fixedly connected to the circumferential side of the main transmission shaft 301 is close to the horizontal state; when cold air enters the third output pipe 215, the cold air will contact the wind direction turning plate 3011 on the circumferential side of the main transmission shaft 301, driving the wind direction turning plate 3011 to rotate clockwise (taking Figure 2 the direction as the standard). The rotation of the wind direction turning plate 3011 drives the main transmission shaft 301 to rotate. Through the transmission cooperation of the main transmission wheel 3041, the slave transmission wheel 3042 and the transmission chain 3043 in the transmission mechanism 304, the rotation of the main transmission shaft 301 drives the slave transmission shaft 305 at the other end of the transmission mechanism 304 to rotate, and then drives the two hexagonal shafts 3082 fixedly connected to the circumferential side of the slave transmission shaft 305 to rotate. The rotation of the hexagonal shafts 3082 can wind up the traction ropes 308 fixedly connected to the circumferential side of the hexagonal shafts 3082. The winding up of the traction ropes 308 realizes the rotation of several blades 3071, and the stretching degree of the traction spring 3081 fixedly connected between the other end of the traction rope 308 and the air inlet plate frame 306 increases until the wind direction turning plate 3011 fixedly connected to the circumferential side of the main transmission shaft 301 contacts the second limiting shaft 303, and several blades 3071 stop rotating. At this time, several blades 3071 are in a horizontal turntable state, realizing that when the treatment device is in a non-use state, several blades 3071 in the ventilation mechanism 3 are in a sealed state. When the treatment device is in a use state, several blades 3071 in the ventilation mechanism 3 are automatically opened, reducing the aging inside the treatment device, realizing the on-off control of the air flow on one side of the treatment device, avoiding the influence of dust entering the ventilation mechanism 3 on the inside of the treatment device, and reducing the influence of dust on the heat dissipation inside the treatment device.
