[0002] Solid-state laser is a holmium laser with a wavelength of 2.1μm. It is a pulsed laser that mainly breaks up stones through thermal effects.

[0032] Furthermore, the input end of the refrigerator 2 is connected to a heat absorption pipe 22, the top of which is connected to a heat absorption tube 221. A heat absorption fan 222 is fixedly mounted on the inner wall of the heat absorption tube 221. A first curved plate 223, a second curved plate 224, and two side plates 225 are installed at the top of the heat absorption tube 221. The first curved plate 223 is located on one side of the laser 11, the second curved plate 224 is located below the laser 11, and the two side plates 225 are located on both sides of the laser 11.

Wind deflector 3011 is rotatably engaged within third output pipe 215.

[0033] Furthermore, a laser power supply 12 is fixedly installed on one side of the equipment box 1 above the ventilation mechanism 3 , an optical fiber interface 13 is provided on one side of the equipment box 1 above the laser power supply 12 , and a display screen 14 is fixedly installed on the top outside the equipment box 1 .

[0034] The therapeutic device of the present invention is mainly composed of an equipment box 1, a refrigerator 2, a laser 11, a laser power supply 12 and an optical fiber interface 13. A foot controller is used outside the equipment box 1 for control, which is not shown in the figure. The optical fiber interface 13 is connected to the optical fiber plug, and the internal laser power supply 12 controls the equipment power supply, and the laser 11 provides the corresponding laser to the outside.

[0035] Laser 11 is a device that can emit laser. A large amount of heat is generated during the operation of laser 11. When the ambient temperature of laser 11 is too high (greater than 35°C), the efficiency of laser diode will decrease (lifespan is halved for every 10°C increase) and the thermal lens effect of crystal will be aggravated. During the use of laser 11, an external cooling system is required to control the temperature of laser 11. When the external ambient temperature and humidity are too high and the water in the air is saturated, since the surface temperature of laser 11 is lower than the dew point temperature of the nearby air, the surface will condense the water in the air and attach it to the laser, and condensation will occur. However, the condensation phenomenon does not necessarily occur only on the outer surface of laser 11. The components and optical devices inside laser 11 are also at risk of condensation, which will affect the performance and service life of the equipment.

[0036] The steps for using the present invention are as follows: after plugging the optical fiber into the optical fiber interface 13, start the power supply of the device, and the medical staff starts the device by foot control. At this time, the laser 11 inside the device box 1 starts running, and 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 intake fan 309 are also started.

[0037] The air flow control principle of the present invention is as follows: after the refrigerator 2 and 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 refrigerator 2 along the path of the heat tube 221-heat absorption tube 22. 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 gas is cooled, it is discharged along the output main pipe 21. The path of the first output pipe 211-the second output pipe 212-the annular pipe 214-the third output pipe 215 in the main pipe 21, and finally the external expansion pipe 216 connected to the top of the third output pipe 215 flows cold air toward the laser 11 and the laser power supply 12 set on the top of the external expansion pipe 216, so that the heat-absorbing fan 222 draws the hot air into the refrigerator 2 for cooling to form cold air, and the cold air expands the low temperature outward through the external expansion pipe 216, realizing the function of cooling the inside of the equipment and achieving the effect of cooling the laser.

[0038] During the cooling process of the laser 11, the cold air converted by the refrigerator 2 passes through the water absorption pipe 213 and the annular pipe 214 in 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 an annular manner. The cold air moves upward and the annular arrangement of the annular pipe 214 causes the water vapor to adhere to the inner wall of the annular pipe 214, and finally flows into the bottom of the water absorption pipe 213 arranged 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, thereby improving the dryness of the cold air, avoiding condensation of the cold air output through the external expansion pipe 216 when encountering the laser 11, and reducing the impact on the use effect and service life of the treatment equipment.

[0039] When the treatment device is started, the blades 3071 on the ventilation mechanism 3 are changed from a sealed state to an open state. The use effect of the blades 3071 is similar to that of blinds. When the blades 3071 are in a sealed state, the traction springs 3081 fixedly connected between the bottom ends of the two traction ropes 308 and the inner wall of the air inlet plate frame 306 are always in a stretched state, so that the blades 3071 are in a vertical state, and the wind direction rotating plate 3011 fixedly connected to the side of the main transmission shaft 301 is close to a horizontal state; when cold air enters the third output pipe 215, the cold air will contact the wind direction rotating plate 3011 on the side of the main transmission shaft 301, driving the wind direction rotating plate 3011 to rotate clockwise (by Figure 2 The direction is standard), the wind direction turning plate 3011 rotates to drive the main transmission shaft 301 to rotate, and 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 main transmission shaft 301 rotates to drive 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 side of the slave transmission shaft 305 to rotate. The rotation of the hexagonal shaft 3082 can reel in the traction rope 308 fixedly connected to the side of the hexagonal shaft 3082. The retraction of the traction rope 308 is realized by rotating several blades 3071, and the traction spring fixedly connected between the other end of the traction rope 308 and the air inlet plate frame 306 The stretching degree of 3081 increases until the wind direction rotating plate 3011 fixedly connected to the side surface of the main transmission shaft 301 contacts the second limit shaft 303, and the plurality of blades 3071 stops rotating. At this time, the plurality of blades 3071 are in a horizontal turntable, so that when the treatment device is not in use, the plurality of blades 3071 in the ventilation mechanism 3 are in a sealed state. When the treatment device is in use, the plurality of blades 3071 in the ventilation mechanism 3 are automatically opened, reducing the aging of the interior of 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 interior of the treatment device, and reducing the influence of dust on the heat dissipation inside the treatment device.
