In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings.

In one embodiment, a fluorescence endoscope is provided that includes a host 10 and an endoscope camera (not shown). The host computer 10 is in light-guiding connection with the endoscope camera, so that emergent light is provided for the endoscope camera by the host computer 10, and therefore, the intraoperative visualization and the focus diagnosis are carried out in the minimally invasive surgery process.

As shown in fig. 1, the host computer 10 includes a light source structure 100, and the light source structure 100 can emit required light to an endoscope camera, so as to perform intra-operative visualization and focus diagnosis in a minimally invasive surgery process. In addition, the light source structure 100 has fewer parts and simpler structure, so that the structure of the host 10 is more compact and the cost can be reduced. Moreover, the light source structure 100 of the embodiments of the present application has higher energy efficiency than the conventional light source structure that uses a laser to generate near infrared light.

It should be noted that, the host 10 may further include a chassis, a power source, a switch, a socket, etc., and the details thereof are not described herein since they may belong to the prior art. Wherein, the light source structure 100 and the power supply are both installed in the chassis, and the power supply is used for supplying power to the light source structure.

As shown in fig. 1 and 2, the light source structure 100 optionally includes an LED near infrared light source 110, an LED white light source 120, an optical film (not shown), and a controller 140.

Wherein, the LED near infrared light source 110 can emit near infrared rays emitted along the first emission path 111. The traditional laser device is used for generating near infrared rays, so that the power consumption is high, the on-off can not be performed frequently, the starting time is long, continuous work is required, and the energy efficiency is low. The embodiment of the application adopts the LED near infrared light source 110 to generate near infrared rays, and can be flexibly electrified or powered off according to the use requirement, namely, the LED near infrared light source can be lightened, the energy consumption is reduced, and the energy efficiency is improved.

Of course, in order to ensure uniformity and straightness of the near infrared light emitted by the LED near infrared light source 110, a light guide cover and other elements may be additionally arranged at the LED near infrared light source 110, so that the near infrared light exits in a straight line along the first exit path 111, thereby reducing optical loss and ensuring light intensity.

Wherein the LED near infrared light source 110 may be in the form of a lamp bead or the like.

As shown in fig. 1 and 2, the light source structure 100 further includes a first light guiding lens 150. The first light guiding lens 150 is disposed between the LED near-infrared light source 110 and the optical film, so that the near-infrared light is guided by the first light guiding lens 150, that is, the near-infrared light is guided, so that the near-infrared light can be better transmitted along the first exit path 111, and light loss is avoided.

The first light guiding lens 150 may be a collimating lens or other existing components capable of guiding near infrared light to transmit along a predetermined path.

As shown in fig. 1, in addition, the light source structure 100 further includes a first heat dissipation element 170. The first heat dissipation element 170 is disposed corresponding to the LED near infrared light source 110, so that the first heat dissipation element 170 is utilized to dissipate heat of the LED near infrared light source 110, thereby avoiding the influence of the overhigh temperature of the LED near infrared light source 110 on the operation and ensuring the reliability and the persistence of the operation of the LED near infrared light source 110.

The first heat dissipation element 170 may be a heat dissipation fan, a heat dissipation fin, or other elements capable of dissipating heat from the LED near infrared light source 110.

In addition, the second exit path 121 and the first exit path 111 are disposed at an included angle, so that the LED near infrared light source 110 and the LED white light source 120 can be flexibly arranged. Meanwhile, the second exit path 121 and the first exit path 111 can intersect at the first intersection point 130, so that the near infrared light and the white light can be converged at the first intersection point 130, and various use requirements are satisfied.

Of course, in order to ensure uniformity and straightness of the white light emitted by the LED white light source 120, a light guide cover and other elements may be additionally arranged at the LED white light source 120, so that the white light is emitted linearly along the second emitting path 121, thereby reducing optical loss and ensuring light intensity.

As shown in fig. 1 and 2, the light source structure 100 further includes a second light guiding lens 160. The second light guiding lens 160 is disposed between the LED white light source 120 and the optical film, so that the white light is guided by the second light guiding lens 160, that is, the white light is guided, so that the white light can be better transmitted along the second exit path 121, and light loss is avoided.

The second light guiding lens 160 may be a collimating lens or other existing components capable of guiding white light to transmit along a predetermined path.

As shown in fig. 1, in addition, the light source structure 100 further includes a second heat dissipation element 180. The second heat dissipation element 180 is disposed corresponding to the LED white light source 120, so that the LED white light source 120 is dissipated by using the second heat dissipation element 180, the operation is prevented from being affected by the excessively high temperature of the LED white light source 120, and the reliability and the persistence of the operation of the LED white light source 120 are ensured.

Wherein the LED white light source 120 may be in the form of a lamp bead or the like.

Wherein the optical film is disposed corresponding to the first intersection point 130, that is, the first intersection point 130 falls on the optical film. And, the optical film can transmit white light, and the optical film can reflect near infrared light to transmit along the second exit path 121. Thus, when the single white light beam is emitted onto the optical film along the second emission path 121, the white light beam is still transmitted along the second emission path 121 through the optical film; when the single near infrared ray exits along the first exit path 111 onto the optical film, the near infrared ray is reflected by the optical film and is redirected to be transmitted along the second exit path 121; when both near infrared rays are emitted onto the optical film along the first emission path 111 and white light rays are emitted onto the optical film along the second emission path 121, the white light rays and the near infrared rays are combined at the first intersection point 130 and then transmitted along the second emission path 121 under the action of the optical film.

The controller 140 is electrically connected to the LED near infrared light source 110 and the LED white light source 120, respectively, so that the controller 140 can control the power on and off of the LED near infrared light source 110 and also control the power on and off of the LED white light source 120.

The electrical connection may be realized by wired connection such as a wire, or may be realized by wireless connection such as bluetooth transmission.

When the light source structure 100 of the embodiment of the present application is used, when a white light source is needed, the controller 140 controls the LED white light source 120 to be powered on and the LED near infrared light source 110 to be powered off, so that when white light rays emitted by the LED white light source 120 are emitted onto the optical film along the second emission path 121, the white light rays still transmit to the endoscope camera along the second emission path 121 after passing through the optical film; when the near infrared light is required to be used, the controller 140 controls the LED white light source 120 to be powered off and the LED near infrared light source 110 to be powered on, so that the near infrared light emitted by the LED near infrared light source 110 is emitted onto the optical film along the first emergent path 111, reflected by the optical film and redirected to be transmitted to the endoscope camera along the second emergent path 121; when both the white light source and the near infrared light are needed, the controller 140 controls the LED white light source 120 to be powered on and the LED near infrared light source 110 to be powered on, so that the white light emitted by the LED white light source 120 is emitted onto the optical film along the second emitting path 121, and the near infrared light emitted by the LED near infrared light source 110 is emitted onto the optical film along the first emitting path 111, and under the action of the optical film, the white light and the near infrared light are combined at the first intersection point 130 and then transmitted to the endoscope camera along the second emitting path 121.

Compared with the traditional arrangement of the filter element, the light source structure 100 of the embodiment of the application omits the filter element, has fewer parts and simpler structure, and can reduce the use cost.

Meanwhile, the controller 140 can flexibly control the light emitting power of the LED white light source 120 and the light emitting power of the LED near infrared light source 110, so that the intensity of white light and the intensity of near infrared light can be flexibly adjusted according to actual use requirements, and diversified use requirements can be met.
