Description

Technical Field

[0001] The utility model relates to the technical field of laser medical equipment, in particular to a dual-mode thulium laser medical equipment. Background Art

[0002] With the rapid development of laser technology, laser medical equipment has been widely used in the medical field, including medical equipment such as surgical treatment, medical imaging and skin beauty. In particular, the wavelength of 2μm band medical equipment is exactly at the absorption peak of human water molecules, and has been used in human lithotripsy and human soft tissue cutting surgery.

[0003] Thulium laser medical equipment outputs laser wavelengths of 1.94μm (fiber) or 2.02μm (solid), with high average laser power (greater than 100W) and low peak power (less than 5kW). The power output at the end of the optical fiber of the equipment can cut human soft tissue, and the equipment can be widely used in human soft tissue cutting surgery. Thulium laser medical equipment can also be used in human lithotripsy, but clinical research results show that the existing thulium laser medical equipment cannot complete lithotripsy for stones with slightly larger hardness CT values ​​during human lithotripsy, due to low peak power, and the lithotripsy is not ideal.

[0004] The output wavelength of the laser of the holmium laser medical device is 2.1μm. The energy output from the end of the optical fiber of the device can vaporize the water between the end of the optical fiber and the stone, forming tiny cavitation bubbles, and transmit the energy to the stone, crushing the stone into powder. The device is widely used in human lithotripsy. However, the holmium laser medical device is prone to cause splitting damage during human soft tissue cutting surgery, and the bleeding is difficult to control. The patient's recovery period is long and the surgical risk is high. Therefore, the holmium laser medical device cannot be well applied to human soft tissue cutting surgery.

[0005] If laser medical equipment is to take into account both human lithotripsy and human soft tissue cutting surgery, the current practice is mainly to merge a holmium laser medical device and a thulium laser medical device to obtain a holmium-thulium laser medical device. Although this device can ideally take into account both human lithotripsy and human soft tissue cutting surgery, the device includes two systems with complex structure, many components and high price, resulting in low equipment utilization efficiency, increased surgical difficulty, increased surgical risks, and increased patient treatment time and medical expenses.

[0035] Combine the following Figure 1 to Figure 3 Describe the specific details of the dual-mode thulium laser medical device of the present invention.

[0036] One embodiment of the utility model provides a dual-mode thulium laser medical device, see Figure 1 As shown, it includes a dual-mode thulium laser module 1, a guiding light module 2, an optical coupling module 3, an optical fiber 4 and an operation and display module 5. The dual-mode thulium laser module 1 modulates the laser repetition frequency and pulse width through a Q switch 13, and adjusts the laser output performance through an output mirror control component 11, so that the dual-mode thulium laser module 1 can selectively output a high peak power greater than 50,000 watts of thulium laser or a high average power greater than 100 watts of thulium laser. The guiding light module 2 is a visible light source (red light / green light); the input end of the optical coupling module 3 is respectively connected to the dual-mode thulium laser module 1 and the guiding light module 2; the optical fiber 4 is connected to the output end of the optical coupling module 3 and is transmitted to the surgical site of the human body; the operation and display module 5 is electrically connected to the dual-mode thulium laser module 1, and is used to control and display the operating status of the dual-mode thulium laser medical device.

[0037] The dual-mode thulium laser medical device in this embodiment can selectively output two different performance thulium laser radiations by adjusting the output performance of the dual-mode thulium laser module 1 through the Q switch 13 and the output mirror control component 11. The thulium laser radiation output by the dual-mode thulium laser module 1 is coupled with the visible light output by the guide light module 2 in the optical coupling module 3, and then transmitted to the surgical site of the human body by the optical fiber 4 for the corresponding surgery. It can realize high peak power (>50,000 watts) thulium laser output as a human lithotripsy laser, and high average power (>100 watts) thulium laser output as a human soft tissue cutting laser. The dual-mode thulium laser medical device can be controlled for mode conversion on the operation and display module 5, and the corresponding mode can be displayed on the operation and display module 5.

[0038] It can be understood that the dual-mode thulium laser medical device of this embodiment can output high peak power (>50,000 watts) thulium laser which is very suitable for human lithotripsy, and can output high average power (>100 watts) thulium laser which is very suitable for human soft tissue cutting surgery. One device can meet the needs of both human lithotripsy and human soft tissue cutting surgery, has a simple structure, improves the efficiency of equipment use, reduces the difficulty of surgery, lowers the risk of surgery, is cheap, and reduces patient pain and medical expenses.

[0039] Specifically, the dual-mode thulium laser module 1 includes an output mirror control component 11, a thulium laser component 12, a Q switch 13, a high reflective mirror 14 and a power module 15, wherein the power module 15 is connected to the thulium laser component 12 to provide continuous wave direct current so that the thulium laser component 12 generates thulium laser radiation; the Q switch 13 is located on the thulium laser radiation path of the thulium laser component 12, and is used to modulate the laser repetition frequency and pulse width, and output nanosecond laser radiation with a low repetition frequency of 100Hz to 1000Hz or output laser radiation with a high repetition frequency greater than 5kHz; the output mirror control component 11 is located on the thulium laser radiation output path, and is used to convert the laser output performance between high peak power and high average power; the high reflective mirror 14 is located on the other side of the thulium laser component 12 relative to the Q switch 13, and is used to reflect laser radiation.

[0040] The output mirror control assembly 11 includes an output mirror position regulator 111, an output mirror controller 112, a high transmittance output mirror 113, a low transmittance output mirror 114, a high transmittance output mirror position feedback device 115, and a low transmittance output mirror position feedback device 116. The output mirror position regulator 111 is located on the thulium laser radiation output path, and can reciprocate in a direction perpendicular to the thulium laser radiation output path; the output mirror controller 112 is connected to the output mirror position regulator 111, and is used to control the output mirror position regulator 111 to move; the high transmittance output mirror 113 is arranged on the output mirror position regulator 111, and is located on one side of the thulium laser radiation output path, and the transmittance of the high transmittance output mirror 113 is greater than 15%; the low transmittance output mirror 114 is arranged at the output mirror position regulator 111. The output mirror 114 has a transmittance of less than 15%. The high transmittance output mirror position feedback device 115 is located on the movement path of the output mirror position regulator 111 and is located on the same side of the thulium laser radiation output path as the low transmittance output mirror 114. The low transmittance output mirror position feedback device 116 is located on the movement path of the output mirror position regulator 111 and is located on the same side of the thulium laser radiation output path as the high transmittance output mirror 113.

[0041] It should be understood that the high transmittance output mirror 113 and the low transmittance output mirror 114 in this embodiment are both film lenses for 2.02 μm wavelength lasers, and the film transmittance satisfies T 高 >T 低 The output mirror position regulator 111 can reciprocate so that the high transmittance output mirror 113 or the low transmittance output mirror 114 located on the output mirror position regulator 111 reaches the position in the laser oscillation process (on the path of the dual-mode thulium laser module 1 outputting laser radiation), and the motion state of the output mirror position regulator 111 is controlled by the output mirror controller 112. The high transmittance output mirror position feedback device 115 and the low transmittance output mirror position feedback device 116 can both be position sensors, which are located on the reciprocating motion path of the output mirror position regulator 111, and their purpose is to feedback that the output mirror position regulator 111 has reached the corresponding position.

[0042] See also Figure 2As shown, the output mirror position regulator 111 moves upward or downward, so that the high transmittance output mirror 113 or the low transmittance output mirror 114 on it can move to the position in the laser oscillation process, respectively satisfying the laser oscillation. When performing human lithotripsy mode, the output mirror position regulator 111 automatically moves downward in the horizontal direction until it contacts the high transmittance output mirror position feedback device 115 to stop moving. At this time, the high transmittance output mirror 113 is located in the position in the laser oscillation process. At this time, the laser working repetition frequency is low, which is convenient for outputting high peak power thulium laser without damaging the laser device, and performing human lithotripsy surgery; when performing human soft tissue cutting mode, the output mirror position regulator 111 automatically moves upward in the horizontal direction until it contacts the low transmittance output mirror position feedback device 116. At this time, the low transmittance output mirror 114 is located in the position in the laser oscillation process. At this time, the laser working repetition frequency is high, effectively maintaining the gain in the laser oscillation cavity, which is convenient for efficient extraction of thulium laser to obtain high average power output, and performing human soft tissue cutting surgery.

[0043] Furthermore, in some other embodiments of a dual-mode thulium laser medical device of the present invention, the output mirror control component 11 also includes a high-transmittance output mirror position regulator 117, a low-transmittance output mirror position regulator 118, a high-transmittance output mirror position adjustment feedback device 119 and a low-transmittance output mirror position adjustment feedback device 110, wherein the high-transmittance output mirror position regulator 117 is installed on the output mirror position regulator 111, and the high-transmittance output mirror 113 is installed on the high-transmittance output mirror position regulator. The low transmittance output mirror position regulator 118 is installed on the output mirror position regulator 111, and the low transmittance output mirror 114 is installed on the low transmittance output mirror position regulator 118; the high transmittance output mirror position adjustment feedback device 119 is connected to the high transmittance output mirror position regulator 117 to feedback the position of the high transmittance output mirror 113; the low transmittance output mirror position adjustment feedback device 110 is connected to the low transmittance output mirror position regulator 118 to feedback the position of the low transmittance output mirror 114.

[0044] It can be understood that in the present embodiment, during the precise adjustment of the laser, the high transmittance output mirror 113 and the low transmittance output mirror 114 are fixed on the output mirror position regulator 111 via the high transmittance output mirror azimuth regulator 117 and the low transmittance output mirror azimuth regulator 118 respectively; the relative positions of the high transmittance output mirror 113 and the low transmittance output mirror 114 during the laser oscillation process are adjusted via the output mirror position regulator 111, the vertical, pitch, and horizontal swing azimuths of the high transmittance output mirror 113 and the low transmittance output mirror 114 are optimized via the high transmittance output mirror azimuth regulator 117 and the low transmittance output mirror azimuth regulator 118, and the high transmittance output mirror azimuth adjustment feedback device 119 and the low transmittance output mirror azimuth adjustment feedback device 110 are used to confirm that the dual-mode laser oscillation amplification requirements are met.

The dehumidification and dustproof seal 16 is used for cleaning, sealing and dehumidifying the internal components of the dual-mode thulium laser module 1.

[0046] In some embodiments, the thulium laser component 12 of the dual-mode thulium laser module 1 includes a thulium laser crystal 121, a continuous diode laser array 122 and a supporting sealing structure. The continuous diode laser array 122 can select a 785nm series continuous diode laser array to pump the thulium laser crystal 121 to generate laser radiation. The thulium laser crystal 121 and the continuous diode laser array 122 are located in the supporting sealing structure. A cooling environment is formed in the supporting sealing structure, and liquid cooling, air cooling or semiconductor cooling sheets can be used for cooling.

[0047] It can be understood that the power module 15 can be a continuous DC power supply, which is used to provide continuous wave DC power to the continuous diode laser array 122; the Q switch 13 is used to modulate the repetition frequency of the laser to achieve nanosecond thulium laser radiation output with different repetition frequencies, low repetition frequency (100Hz~1000Hz) corresponds to high peak power laser, and high repetition frequency (greater than 5KHz) corresponds to high average power laser; the high reflective mirror 14 can be a high reflective mirror for 2.02μm wavelength, which is installed on a precision adjustment fixed structure.

[0048] For some specific examples, see Figure 1 As shown, the thulium laser crystal 121 is a rod-shaped structure or a slab structure, and the continuous diode laser array 122 is located on the side of the thulium laser crystal 121. The power module 15 provides continuous wave direct current to the continuous diode laser array 122 to pump the thulium laser crystal 121 to generate laser radiation. The radiation wave generated on one side of the thulium laser crystal 121 directly enters the Q switch 13, and the radiation wave generated on the other side also enters the Q switch 13 after being reflected by the high reflective mirror 14.

[0049] For some specific examples, see Figure 3As shown, the thulium laser crystal 121 is a rod-shaped structure, a slab structure or a block-shaped structure, the continuous diode laser array 122 is located at one end face of the thulium laser crystal 121, and the high reflective mirror 14 is located between the thulium laser crystal 121 and the continuous diode laser array 122. The power module 15 provides continuous wave direct current to the continuous diode laser array 122, and the continuous diode laser array 122 first pumps the thulium laser crystal 121 through the high reflective mirror 14, and the thulium laser crystal 121 generates laser radiation. The radiation wave generated on one side of the thulium laser crystal 121 directly enters the Q switch 13, and the radiation wave generated on the other side also enters the Q switch 13 after being reflected by the high reflective mirror 14.

[0052] In the human lithotripsy mode, the dual-mode thulium laser module 1 outputs high-peak power thulium laser radiation greater than 50,000 watts. The output thulium laser radiation is coupled with the visible light output by the guide light module 2 in the optical coupling module 3, and then transmitted to the human surgical site through the optical fiber 4 for lithotripsy.

[0053] Specifically, in human lithotripsy modalities:

[0054] The thulium laser crystal 121 is pumped by a continuous diode laser array 122 to generate thulium laser radiation;

[0059] In the human soft tissue cutting surgery mode, the dual-mode thulium laser module 1 outputs high average power thulium laser radiation greater than 100 watts. The output thulium laser radiation is coupled in the optical coupling module 3 with the visible light output by the guide light module 2, and then transmitted to the human surgical site through the optical fiber 4 for soft tissue cutting surgery.

[0060] Specifically, in human soft tissue cutting surgical modalities:

[0066] In some specific examples, the dual-mode thulium laser medical device can adjust the human lithotripsy surgical mode and the human soft tissue cutting surgical mode by one button through the operation and display module 5; when the human lithotripsy surgical mode is adjusted through the operation and display module 5, the high-transmittance output mirror 113 automatically translates to the position in the laser oscillation process, and the power module 15 provides continuous wave direct current to the continuous diode laser array 122. The selected high-transmittance output mirror 113 has a transmittance of 40% for 2.02μm wavelength laser, and the power density in the laser oscillation cavity is only 4 times that outside the cavity.
