Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, which shows a schematic structural diagram of an endoscope provided by an embodiment of the present application, the endoscope provided by the embodiment of the present application may include:
a first white light source 1 for providing white light;
a red light source 2 for providing red light;
the control switch is connected with the first white light source 1 and the red light source 2;
a camera 3 for shooting a subject containing a photosensitizer in a white light environment to obtain a first shot image and shooting the subject in a red light environment to obtain a second shot image;
and the communication component is connected with the camera 3 and is used for transmitting the first shot image and the second shot image.
When a certain tissue in a human body has tumor lesion, the photosensitizer provided for the human body enters tumor cells and is combined with the tumor cells to show a fluorescence phenomenon, and in addition, the photosensitizer also enters the interior of the tumor cells and is distributed in organelles such as mitochondria, cell nucleus and Golgi body in the tumor cells, and the photosensitizer is combined with the organelles to show the fluorescence phenomenon. For example: after several hours of administration of 5-aminolevulinic acid (5-ALA) to the venous system of a patient (5-ALA negative skin test) for onset, protoporphyrin (PpIX) (photosensitizer) is formed after a series of intracellular reactions with 5-ALA, which binds Fe under the action of ferrochelatase2+And generating heme. Since tumor metabolism is faster than that of normal cells, more PpIX is produced in mitochondria of tumor cells than in normal cell tissues, and iron chelate enzyme activity is reduced in rapidly growing cells and the activity of porphobilinogen deaminase is increased, which all cause more PpIX to be produced in tumor cells, and a part of PpIX enters into cytoplasm and distributes around nucleus, endoplasmic reticulum and lysosome, which increases the concentration of PpIX in cells (wherein the tissue concentration around the inner wall of gastrointestinal tumor is 8-15 times higher), at which time, tumor cells can be localized according to the fact that PpIX has red fluorescence.
Based on the above-mentioned fluorescence phenomenon, the present application provides an endoscope to help a doctor accurately find the location of a tumor lesion and to help the doctor improve the accuracy of surgical incision.
Specifically, the endoscope provided by the application comprises a first white light source 1, a red light source 2, a control switch, a camera 3 and a communication assembly, and in addition, the endoscope further comprises a power supply for supplying electric energy to the first white light source 1 and the red light source 2.
The control switch is connected with the first white light source 1 and the red light source 2 and is used for controlling whether the first white light source 1 and the red light source 2 work or not. The first white light source 1 is used for providing white light, and the camera 3 is used for shooting a shot object containing a photosensitizer in a white light environment so as to correspondingly obtain a first shot image, namely an image which is the same as the real model of the shot object. The red light source 2 is used for providing red light, and the camera 3 is used for shooting the shot object in a red light environment so as to correspondingly obtain a second shot image. The photosensitizer is delivered into a human body in advance before shooting a shot object in the human body, and specifically any one photosensitizer or any combination of multiple photosensitizers which can be clinically combined with tumor cells to generate a fluorescence phenomenon, and the type of the photosensitizer is not limited in any way, for example: the above-mentioned 5-ALA may be administered to a patient to produce PpIX, a photosensitizer in the human body, and the endoscope provided herein may be inserted into the human body to work in the human body to take a picture when 5-ALA reaches a peak concentration in the human body. In addition, the endoscope may specifically include a plurality of first white light sources 1 and a plurality of red light sources 2 to improve the shooting quality of the first shot image and the second shot image.
It should be noted that, when the first white light source 1 provides white light to make the camera 3 shoot an object in a white light environment, the red light source 2 may be in an on state or may also be in an off state, and the state does not affect the first shot image. When the red light source 2 provides red light to make the camera 3 shoot the object under the red light environment, the first white light source 1 needs to be in a closed state to avoid influencing the second shot image. In addition, it should be noted that the camera 3 can rapidly and alternately perform shooting in an environment of white light and red light to alternately obtain the first shot image and the second shot image, so as to obtain the related information of a relatively large number of objects to be shot.
The communication assembly is connected with the camera 3 and is used for transmitting a first shot image and a second shot image shot by the camera 3 in real time, so that a doctor can determine whether tumor lesion exists according to the first shot image and the second shot image and store the first shot image and the second shot image in real time, and follow-up examination and analysis are facilitated.
When the shot object has tumor lesion, the photosensitizer can be combined with tumor lesion cells, and releases energy to emit fluorescence when the red light irradiates, and accordingly, a fluorescence signal can appear in the second shot image, at the moment, a doctor can determine whether the shot object has the tumor lesion or not through whether the fluorescence signal exists in the second shot image or not, and if the tumor lesion exists, the doctor can compare the second shot image with the first shot image to determine the specific position of the tumor lesion, so that the certainty of determining the position of the tumor lesion by the doctor is improved, the doctor is helped to improve the accuracy of surgical cutting, and meanwhile, the doctor is helped to judge whether the tumor lesion is completely cut or not. In addition, the photosensitizer can be combined with organelles inside tumor lesion cells to generate a fluorescence phenomenon and generate a fluorescence signal under the irradiation of red light, so that the endoscope can also help doctors to timely generate tumor lesions at a cell level and below the cell level, namely the endoscope provided by the application can improve the accuracy of tumor lesion identification so as to help doctors to improve the accuracy of tumor lesion determination. Moreover, because the wavelength of the red light is longer and the energy is lower, the temperature of the red light is not so high during irradiation, and the comfort level of the human body can be improved.
In addition, because the red light has the penetrability of a certain tissue depth, even if the shot object is covered by the secretion, the shooting and the detection of the shot object cannot be influenced, and the probability of misjudgment can be reduced.
According to the technical scheme, according to the principle that the photosensitizer can enter tumor lesion tissues and can be combined with organelles in the tumor lesion tissues to show a fluorescence phenomenon under infrared irradiation, the endoscope is internally provided with the first white light source and the red light source, the control switch, the camera and the communication component are arranged, so that the first white light source and the red light source respectively work through the control switch, the camera is used for shooting a shot object containing the photosensitizer in a white light environment to obtain a first shot image, the camera is used for shooting the shot object containing the photosensitizer in a red light environment to obtain a second shot image, then the communication component is used for transmitting the first shot image and the second shot image, so that a doctor can determine whether the shot object or the organelles of the shot object have the tumor lesion by means of the first shot image and the second shot image, and when the existence of the tumor lesion is determined, the position of the tumor lesion is accurately determined by means of the fluorescence signal shot in the second shot image and the shot first shot image, so that a certain reference is provided for the surgical incision of a doctor, and the surgical incision accuracy of the doctor is improved.
