That is, the control assembly 7 can also control the visible light assembly 5 and the laser assembly 6 to simultaneously emit corresponding visible light and infrared light, or to emit corresponding visible light and infrared light in turn according to a preset time period. The AC / DC power supply 4 is used to convert AC power and DC power. In this embodiment, the control assembly 7 can be used to control the AC / DC power supply 4 to provide DC power to the laser assembly 6.

[0080] In this embodiment, the visible light component 5 is arranged on the side of the optical path coupler 3 away from the front side plate 12, and the laser component 6 is arranged on the side of the AC / DC power supply 4 away from the front side plate 12. Since the working performance of the laser component 6 is greatly affected by temperature, and the optical path coupler 3 generates more heat when working, the laser component 6 is arranged on the rear side of the AC / DC power supply 4, so that the laser component 6 is isolated from the optical path coupler 3, so that the working performance of the laser component 6 is more stable. In addition, the AC / DC power supply 4 and the laser component 6 are arranged adjacent to each other, thereby shortening the connection line between the AC / DC power supply 4 and the laser component 6, saving the installation space of the endoscope light source host 100, and making the overall layout more reasonable and compact.

[0081] Optionally, the optical coupler 3 and the AC / DC power supply 4 and the visible light component 5 and the laser component 6 are arranged in parallel along a direction parallel to the display surface of the display screen 21, and the optical coupler 3 and the visible light component 5 and the AC / DC power supply 4 and the laser component 6 are arranged in parallel along a direction perpendicular to the display surface of the display screen 21 (i.e., the second direction Y). In this way, by reasonably arranging the optical coupler 3, the AC / DC power supply 4, the visible light component 5 and the laser component 6, the space can be effectively utilized in the assembly of the endoscope light source host 100, so that the endoscope light source host 100 has a compact layout and a reasonable center of gravity.

[0082] It should be noted that the term "arranged in parallel" used in the present invention means that a plurality of elements are arranged in a predetermined direction and in a sequential order. The projections of the plurality of elements in a direction parallel to the predetermined direction may not overlap; or they may overlap at least partially, and the projections in a direction perpendicular to the predetermined direction at least overlap.

[0083] Please also see Figure 5 and Figure 6 The visible light component 5 includes a visible light chip 51, a heat conductor 52 and a first radiator 53 which are arranged in sequence from front to back. The optical path coupler 3 is arranged on the side of the visible light chip 51 away from the heat conductor 52. The heat conductor 52 is used to transfer the heat generated by the visible light chip 51 to the first radiator 53, so that the first radiator 53 can dissipate heat for the visible light chip 51. The visible light component 5 also includes a first fan 54 arranged on the side of the first radiator 53 away from the visible light chip 51, and the first fan 54 is connected to the first exhaust port 131 provided on the rear side plate 13. In this way, the heat generated by the visible light chip 51 can be transferred to the first radiator 53 through the heat conductor 52, and then the heat is discharged to the outside of the chassis 1 by the first fan 54, thereby greatly reducing the heat generated by the visible light chip 51 from being dissipated to the inside of the box 102 and interfering with the performance of the laser component 6, thereby improving the working stability and reliability of the laser component 6.

[0084] Among them, the visible light chip 51 includes, but is not limited to, LED, halogen lamp, etc. The visible light chip 51 is used to provide a visible light source. The visible light source is white light. In this embodiment, the visible light chip 51 may include a blue LED chip, a red LED chip, and a green LED chip. The blue light emitted by the blue LED chip, the red light emitted by the red LED chip, and the green light emitted by the green LED chip can be mixed in a certain proportion to obtain the white light. The first radiator 53 is used to dissipate the heat of the visible light chip 51. The first fan 54 is used to discharge the heat of the first radiator 53 out of the chassis 1.

[0085] The visible light component 5 also includes a mounting seat 55 for fixing the visible light chip 51, and the visible light chip 51 is sandwiched between the optical path coupler 3 and the mounting seat 55. A receiving space 501 for receiving the visible light chip 51 is formed between the mounting seat 55 and the optical path coupler 3. In this way, the connection line between the visible light component 5 and the optical path coupler 3 is shortened to reduce the leakage of light emitted by the visible light chip 51.

[0086] In this embodiment, the mounting seat 55 is fixed on the optical coupler 3 to save the installation space of the endoscope light source host 100, making the overall layout more reasonable and compact. The mounting seat 55 can be fixedly connected to the optical coupler 3 by screw locking, snap-fitting, etc., so that the visible light chip 51 is located in the receiving space 501. In some variant embodiments, the mounting seat 55 can also be fixed on the chassis 1.

[0087] Optionally, the heat conductive member 52 is bent toward the side of the left side plate 14 or the right side plate 15 close to the box body 102, and the heat conductive member 52 is partially attached to the left side plate 14 or the right side plate 15 of the box body 102. In this way, the mounting seat 55, the heat conductive member 52 and the first radiator 53 are jointly formed to form an escape space for accommodating the control component 7, thereby further saving the installation space of the endoscope light source host 100, making the overall layout more reasonable and compact. In addition, since the heat conductive member 52 is partially attached to the left side plate 14 or the right side plate 15 of the box body 102, the heat dissipated by the visible light chip 51 can be partially discharged to the outside of the chassis 1 through the shell of the box body 102, thereby further improving the heat dissipation efficiency of the visible light chip 51.

[0088] Specifically, the first heat sink 53 includes heat dissipation fins 531. The heat conducting member 52 includes a first fixing portion 521 fixed on the mounting seat 55, a second fixing portion 522 fixed on the heat dissipation fins 531, and a connecting portion 523 connecting the first fixing portion 521 and the second fixing portion 522, wherein the first fixing portion 521 and the second fixing portion 522 are both bent relative to the connecting portion 523.

[0089] The first fixing portion 521 is disposed on the side of the mounting base 55 away from the visible light chip 51 , and the connecting portion 523 of the heat conducting member 52 is attached to the left plate 14 or the right plate 15 of the box 102 .

[0090] The orthographic projection of the first fixing portion 521 on the mounting base 55 overlaps with the orthographic projection of the visible light chip 51 on the mounting base 55, so that the heat of the visible light chip 51 can be quickly discharged through the mounting base 55 and the first fixing portion 521 of the heat conducting member 52, thereby improving the reliability of the working performance of the visible light chip 51.

[0091] The mounting seat 55 is fixed on the optical path coupler 3. A groove 551 is provided on the side of the mounting seat 55 away from the optical path coupler 3, and the first fixing portion 521 of the heat conductive member 52 is embedded in the groove 551, thus saving the installation space occupied by the heat conductive member 52 on the endoscope light source host 100. In this embodiment, the groove 551 is a through groove provided on the mounting seat 55, thus simplifying the processing technology of the mounting seat 55, and increasing the contact area between the heat conductive member 52 and the mounting seat 55, thereby improving the heat conduction efficiency of the heat conductive member 52.

[0092] The heat conducting member 52 includes one or more heat conducting pipes. The multiple heat conducting pipes are arranged in sequence from top to bottom to improve the heat conducting efficiency of the heat conducting member 52, and at the same time reduce the installation space occupied by the heat conducting member 52 in the endoscope light source host 100, so as to make the overall layout of the endoscope light source host 100 more reasonable and compact. The heat conducting pipe is a metal pipe, such as a copper pipe, an aluminum pipe, etc. In this embodiment, the heat conducting member 52 includes two copper pipes arranged in sequence from top to bottom. In some embodiments, the heat conducting pipe can be loaded with a heat dissipation liquid to further improve the heat dissipation efficiency of the LED chip.

[0093] In an embodiment, the control component 7 includes a power drive management board 71 and a light source drive board 72 electrically connected to the visible light component 5 and the laser component 6. The power drive management board 71 and the light source drive board 72 are both arranged between the visible light chip 51 and the first heat sink 53, and are isolated from the heat conductor 52. Among them, the power drive management board 71 is used to control the visible light component 5 and the laser component 6 to output the visible light source and the laser light source according to the set parameters, so that the visible light component 5 and the laser component 6 output the visible light source and the laser source of the target energy. The endoscope light source host 100 provides power to the visible light component 5 and the laser component 6 through the light source drive board 72. In this way, the distance between the visible light chip 51 and the laser component 6 and the power drive management board 71 and the light source drive board 72 is shortened, thereby avoiding the problem of mutual entanglement and scattered discharge caused by long cables. In addition, since the power drive management board 71 and the light source drive board 72 are isolated from the heat conductor 52, the heat of the heat conductor 52 is prevented from being transferred to the power drive management board 71 and the light source drive board 72, thereby preventing the power drive management board 71 and the light source drive board 72 from being overheated and affecting their working performance.

[0094] Optionally, the orthographic projections of the power drive management board 71 and the light source drive board 72 on the bottom plate 11 of the box 102 do not overlap with the orthographic projections of the heat conductor 52 on the bottom plate 11 of the box 102. In this way, the heat conductor 52 interferes with the assembly of the power drive management board 71 and the light source drive board 72, thereby facilitating the assembly of the power drive management board 71 and the light source drive board 72.

[0095] In this embodiment, the power drive management board 71 and the light source drive board 72 are stacked, thereby saving the installation space of the endoscope light source host 100, making the overall layout more reasonable and compact, and thus reducing the external dimensions of the endoscope light source host 100. The power drive management board 71 and the light source drive board 72 are detachably connected together through the support rod 73, and the power drive management board 71 is arranged above the light source drive board 72. It can be understood that since there are more card-position sockets on the light source drive board 72, the light source drive board 72 is fixedly arranged on the bottom plate 11 of the box 102, that is, arranged below the power drive management board 71, so as to facilitate the connection cable to be plugged into the corresponding card-position socket, and ensure the connection stability and reliability between the various functional elements. In some deformable embodiments, the power drive management board can also be arranged below the light source drive board.

[0096] Optionally, the power drive management board 71 and the light source drive board 72 are both arranged parallel to the bottom plate 11 of the box body 102 to ensure the flatness of the power drive management board 71 and the light source drive board 72, thereby facilitating the corresponding connecting cables to be plugged into the card sockets of the power drive management board 71 and the light source drive board 72, and improving the connection reliability of the corresponding connecting cables to be plugged into the card sockets of the power drive management board 71 and the light source drive board 72.

[0097] In some modified embodiments, the power drive management board 71 and the light source drive board 72 are constructed into a multifunctional integrated circuit board, so as to facilitate the assembly of the power drive management board 71 and the light source drive board 72, and save the installation space occupied by the power drive management board 71 and the light source drive board 72 in the endoscope light source host 100, so that the overall layout of the endoscope light source host 100 is more reasonable and compact, thereby reducing the external dimensions of the endoscope light source host 100.

[0098] In this embodiment, the control assembly 7 further includes a main control board 74. The main control board 74 is fixedly arranged on a side of the front side plate 12 close to the AC / DC power supply 4. The main control board 74 is electrically connected to the visible light assembly 5 and the laser assembly 6 through the light source driving board 72. Specifically, the main control board 74 is located between the front side plate 12 and the AC / DC power supply 4, and is arranged at a position of the front side plate 12 corresponding to the display screen 21.

[0099] It can be understood that the main control board 74 is used to coordinate and control the various boards and devices in the endoscope light source host 100. In this embodiment, the main control board 74 is used to control the data interaction between the power drive management board 71 and the light source driver board 72, as well as the transmission of control signals, and transmit the set light source lighting parameters to the display screen 21 for display, and can also receive user control instructions input from the display screen 21 or physical input interfaces such as keyboards and buttons, and of course can also output control signals on how to set light source lighting parameters. In some variant embodiments, the power drive management board 71, the light source driver board 72 and the main control board 74 can be constructed as a multifunctional integrated circuit board.

[0100] The laser assembly 6 includes a laser 61 and a second heat sink 62 arranged in sequence from front to back, and an AC / DC power supply 4 is arranged on the side of the laser 61 away from the second heat sink 62. In this way, it is convenient to electrically connect the AC / DC power supply 4 to the laser 61, so that the AC / DC power supply 4 provides a DC power supply for the laser 61.

[0101] The laser assembly 6 further includes a second fan 63 disposed on the second radiator 62 away from the laser 61, the second fan 63 is connected to the first exhaust port 132 disposed on the rear side plate 13, and the second fan 63 and the first fan 54 are disposed on both sides of the rear side plate 13 of the box body 102. In this way, the heat dissipation work of the first radiator 53 and the first fan 54 on the visible light chip 51 does not interfere with the heat dissipation work of the second radiator 62 and the second fan 63 on the laser 61, thereby improving the stability and reliability of the working performance of the laser 61.

[0102] Optionally, in some embodiments, the endoscope light source host 100 further includes a cooling component 8 , which is disposed close to the light guide interface 1001 and is used to cool the light guide interface 1001 .

[0103] In the present embodiment, the cooling component 8 is disposed between the optical path coupler 3 and the AC / DC power supply 4. The cooling component 8 is a turbofan, and the exhaust port of the turbofan is aligned with the connection point where the light guide interface 1001 is connected to the external light guide 200. In this way, the wind blown by the turbofan can be used to dissipate heat to reduce the temperature of the connection point where the light guide interface 1001 is connected to the external light guide 200, thereby improving the user experience. In this way, by using the turbofan, a larger air volume can be output in a smaller space occupation, and the heat dissipation effect can be improved. In some other embodiments, when the endoscope light source host 100 is large enough, the cooling component 8 can also be an ordinary fan, that is, a fan whose gas flow is perpendicular to the rotating shaft, to cool the light guide interface 1001.

[0104] Specifically, the light guide interface 1001 is provided with an air inlet 10011 and an air outlet 10012 in the circumferential direction thereof, which are connected to the air duct of the cooling component 8. The cooling component 8 is fixedly arranged on the bottom plate 11 of the box body 102, and a plurality of through holes 111 are arranged below the cooling component 8 or at the bottom periphery thereof corresponding to the bottom plate 11 of the box body 102, which are connected to the air duct of the cooling component 8.

[0105] The present invention provides an endoscope light source host and an endoscope system, wherein the optical path coupler and the AC / DC power supply are arranged near the front side panel in the chassis, and the visible light component and the laser component are arranged near the rear side panel in the chassis, and the optical path coupler and the AC / DC power supply and the visible light component and the laser component are arranged in sequence along the direction parallel to the display surface of the display screen, so that the overall structure of the endoscope light source host is compact and the force is evenly distributed, thereby reducing the overall size of the entire endoscope light source host and facilitating transfer. In addition, the heat of the visible light chip is transferred to the first radiator through the heat conductor, and the first fan directly discharges the heat of the first radiator out of the chassis, thereby avoiding the heat dissipation of the first radiator interfering with the heat dissipation of the laser, thereby improving the stability and reliability of the working performance of the laser.
