In this way, by reasonably arranging the optical coupler 3, the AC/DC power supply 4, the visible light module 5, and the laser module 6, the space can be effectively utilized in the assembly of the entire light source main unit 100 for an endoscope, and the entire light source main unit 100 for an endoscope is compact in layout and reasonable in center of gravity.

It should be noted that, as used herein, the term "juxtaposed" means that a plurality of elements are arranged in a predetermined direction and in a sequential order. Wherein projections of the plurality of elements in a direction parallel to the preset direction may not overlap; alternatively, at least some overlap is possible, and projections in a direction perpendicular to the predetermined direction at least partially overlap.

Referring to fig. 5 and 6 together, the visible light assembly 5 includes a visible light chip 51, a heat conducting member 52 and a first heat sink 53 sequentially arranged from front to back. The side of the visible-light chip 51 facing away from the heat conducting member 52 is provided with the optical path coupler 3. The heat conducting member 52 is used for transferring heat generated by the visible light chip 51 to the first heat sink 53, so that the first heat sink 53 can dissipate heat of the visible light chip 51. The visible light assembly 5 further includes a first fan 54 disposed on a side of the first heat sink 53 away from the visible light chip 51, and the first fan 54 is communicated with a first exhaust opening 131 disposed on the rear side plate 13. Therefore, heat generated by the visible light chip 51 can be transferred to the first heat sink 53 through the heat conducting member 52, and then the heat is discharged to the outside of the case 1 by the first fan 54, so that the interference of the heat generated by the visible light chip 51 to the inside of the case 102 and the performance of the laser assembly 6 is greatly reduced, and the stability and reliability of the operation of the laser assembly 6 are improved.

The visible light chip 51 includes, but is not limited to, an LED, a halogen lamp, and the like. The visible light chip 51 is used to provide a visible light source. The visible light source is white light. In the present 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 according to a certain proportion to obtain the white light. The first heat sink 53 is used to dissipate heat of the visible light chip 51. The first fan 54 is used to discharge the heat of the first radiator 53 to the outside of the cabinet 1.

The visible light module 5 further includes a mount 55 for fixing the visible light chip 51, and the visible light chip 51 is sandwiched between the optical path coupler 3 and the mount 55. An accommodating space 501 for accommodating the visible light chip 51 is defined between the mounting seat 55 and the optical coupler 3. In this way, the connection line between the visible light module 5 and the optical path coupler 3 is shortened to reduce leakage of light emitted from the visible light chip 51.

In the present embodiment, the mounting seat 55 is fixed to the optical coupler 3, so as to save the mounting space of the light source main unit 100 for an endoscope, and make the layout of the whole device more reasonable and compact. The mounting seat 55 may be fixedly connected to the optical coupler 3 by a screw locking method, a clamping method, or the like, so that the visible light chip 51 is located in the accommodating space 501. In some variant embodiments, the mounting seat 55 may also be fixed to the chassis 1.

Alternatively, the heat-conducting member 52 is bent toward a side close to the left or

right side plate

14 or 15 of the case 102, and the heat-conducting member 52 is partially attached to the left or

right side plate

14 or 15 of the case 102. Thus, the mounting seat 55, the heat conducting member 52 and the first heat sink 53 together enclose a space for accommodating the control unit 7, thereby further saving the mounting space of the light source main unit 100 for an endoscope and making the overall layout more reasonable and compact. In addition, since the heat conducting member 52 is partially attached to the left side plate 14 or the right side plate 15 of the box 102, the heat dissipated by the visible light chip 51 can be partially exhausted out of the chassis 1 through the casing of the box 102, thereby further improving the heat dissipation efficiency of the visible light chip 51.

Specifically, the first heat sink 53 includes heat dissipating 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 dissipating fins 531, and a connecting portion 523 connecting the first fixing portion 521 and the second fixing portion 522, wherein both the first fixing portion 521 and the second fixing portion 522 are bent with respect to the connecting portion 523.

The first fixing portion 521 is disposed on a side of the mounting seat 55 away from the visible light chip 51, and the connecting portion 523 of the heat conducting member 52 is attached to the left side plate 14 or the right side plate 15 of the case 102. In the present embodiment, the connecting portion 523 of the heat-conducting member 52 is attached to the left side plate 14 of the case 102.

The orthographic projection of the first fixing portion 521 on the mounting seat 55 is overlapped with the orthographic projection of the visible light chip 21 on the mounting seat 55, so that the heat of the visible light chip 21 can be quickly discharged through the mounting seat 55 and the first fixing portion 521 of the heat-conducting member 52, and the reliability of the working performance of the visible light chip 21 is improved.

The mount 55 is fixed to the optical path coupler 3. The side of the mounting seat 55 facing away from the optical coupler 3 is provided with a groove 551, and the first fixing portion 521 of the heat conducting member 52 is embedded in the groove 551, so that the mounting space of the light source main unit 100 for an endoscope occupied by the heat conducting member 52 is saved. In the present embodiment, the groove 551 is a through groove disposed on the mounting seat 55, so that the processing process of the mounting seat 55 is simplified, and the contact area between the heat conducting member 52 and the mounting seat 55 is increased, thereby improving the heat conducting efficiency of the heat conducting member 52.

The thermally conductive member 52 includes one or more thermally conductive tubes. The plurality of heat conducting pipes are sequentially arranged from top to bottom, so that the heat conducting efficiency of the heat conducting member 52 is improved, and meanwhile, the heat conducting member 52 occupies the installation space of the light source main unit 100 for the endoscope, so that the overall layout of the light source main unit 100 for the endoscope is more reasonable and compact. The heat conduction pipe is a metal pipe, such as a copper pipe, an aluminum pipe and the like. In the present embodiment, the heat-conducting member 52 includes two copper pipes arranged in this order from top to bottom. In some embodiments, a heat dissipating liquid may be loaded in the heat conducting tube to further improve the heat dissipating efficiency of the LED chip.

In the embodiment, the control unit 7 includes a power supply drive management board 71 and a light source drive board 72 electrically connected to the visible light unit 5 and the laser unit 6. The power driving management board 71 and the light source driving board 72 are both disposed between the visible light chip 51 and the first heat sink 53, and are disposed apart from the heat conductive member 52. The power driving management board 71 is configured to control the visible light module 5 and the laser module 6 to output the visible light source and the laser source according to the set parameters, so that the visible light module 5 and the laser module 6 output the visible light source and the laser source with target energy. The light source unit 100 for an endoscope supplies power to the visible light unit 5 and the laser unit 6 via the light source driving board 72. Thus, the distances between the visible light chip 51 and the laser module 6 and the power drive management board 71 and the light source drive board 72 are shortened, and the problems of mutual winding and scattered discharge caused by the long cables are avoided. In addition, since the power driving management plate 71 and the light source driving board 72 are disposed separately from the heat conductive member 52, heat of the heat conductive member 52 is prevented from being transferred to the power driving management plate 71 and the light source driving board 72, and the power driving management plate 71 and the light source driving board 72 are prevented from being overheated to affect the workability.

Alternatively, the orthographic projections of the power drive management board 71 and the light source drive board 72 on the bottom plate 11 of the case 102 and the orthographic projection of the heat conductive member 52 on the bottom plate 11 of the case 102 do not overlap. In this way, the heat conductive member 52 interferes with the assembly of the power driving management board 71 and the light source driving board 72, thereby facilitating the assembly of the power driving management board 71 and the light source driving board 72.

In the present embodiment, the power supply driving management board 71 and the light source driving board 72 are stacked, so that the installation space of the light source main unit 100 for an endoscope is saved, the layout of the whole device is more reasonable and compact, and the overall size of the light source main unit 100 for an endoscope can be reduced. The power drive management board 71 and the light source driving board 72 are detachably connected together by a support rod 73, and the power drive management board 71 is disposed above the light source driving board 72.

In some variant embodiments, the power drive management board may also be disposed below the light source driving board.

Optionally, the power driving management board 71 and the light source driving board 72 are both disposed in parallel with respect to the bottom plate 11 of the box 102 to ensure flatness of the power driving management board 71 and the light source driving board 72, so that the corresponding connection cables can be conveniently plugged into the locking sockets of the power driving management board 71 and the light source driving board 72, and connection reliability of the corresponding connection cables plugged into the locking sockets of the power driving management board 71 and the light source driving board 72 is improved.

In some modified embodiments, the power driver management board 71 and the light source driving board 72 are configured as a multifunctional integrated circuit board, so as to facilitate the assembly of the power driver management board 71 and the light source driving board 72, and save the installation space of the light source host 100 for an endoscope occupied by the power driver management board 71 and the light source driving board 72, so that the overall layout of the light source host 100 for an endoscope is more reasonable and compact, and the overall size of the light source host 100 for an endoscope can be reduced.

In some variant embodiments, the power driving management board 71, the light source driving board 72 and the main control board 74 may be configured as one multifunctional integrated circuit board.

The laser assembly 6 comprises a laser 61 and a second heat sink 62 which are arranged in sequence from front to back, and an AC/DC power supply 4 is arranged on one side of the laser 61, which is far away from the second heat sink 62.
