Description

Technical Field

[0001] This application relates to the field of medical device manufacturing technology, and in particular to an endoscope probe based on a dual-lens telescope with adjustable focal length. Background Technology

[0002] An endoscope is an important medical tool used to examine internal organs and tissues of the human body. It can be inserted into the body through natural cavities or minimally invasive surgical incisions to provide doctors with intuitive image information, playing an irreplaceable role in assisting doctors in disease diagnosis and surgical treatment.

[0003] In related technologies, imaging lasers and ablation lasers can share the same optical path to a movable mirror via a reflector and a semi-transparent mirror, achieving integrated diagnosis and treatment; alternatively, the near-infrared laser signals emitted and received by optical coherence tomography (OCT) itself can be used as the basis for adjusting the working distance of the endoscope, achieving self-focusing OCT imaging with a variable working distance; or the first light emitted by the light source can be transmitted through an optical fiber to a first superlens for light modulation, forming a structured light pattern and projecting it onto the area to be measured to achieve three-dimensional imaging, thereby performing laser ablation surgery.

[0004] However, in related technologies, the focal length of the endoscopic probe is fixed, requiring the replacement of probes with different focal lengths or adjustment of the position of the endoscopic probe to examine tissues at different depths. This operation is cumbersome and can easily affect the accuracy and efficiency of diagnosis and treatment. In addition, it cannot achieve the goal of integrated diagnosis and treatment, and cannot effectively improve surgical efficiency. It has certain limitations in practical applications and urgently needs improvement. Summary of the Invention

[0005] This application provides an endoscope probe based on a dual-lens telescope with adjustable focal length to solve the problems in related technologies, such as the need to replace probes with different focal lengths or adjust the position of the endoscope probe to examine tissues at different depths, which is cumbersome, affects the accuracy and efficiency of diagnosis and treatment, fails to achieve the goal of integrated diagnosis and treatment, reduces surgical efficiency, and has certain limitations in practical applications.

[0006] The first aspect of this application provides an endoscopic probe based on a dual-lens telescope with adjustable focal length, comprising: a first lens for coupling initial ablation light to obtain ablation light coupled to the initial ablation light; a second lens for coupling initial imaging light to obtain imaging light coupled to the initial imaging light; a MEMS (Micro-Electro-Mechanical Systems) galvanometer for reflecting the coupled imaging light based on lesion tissue to obtain reflected imaging light; a dual-lens telescope for adjusting the focal length of the reflected imaging light to obtain reflected imaging light with adjusted focal length; and a dichroic mirror for reflecting the coupled ablation light and transmitting the reflected imaging light with adjusted focal length to obtain reflected ablation light and transmitted imaging light, and scanning the reflected ablation light and transmitted imaging light onto the lesion tissue to generate a scanning result of the lesion tissue.

[0007] Optionally, in one embodiment of this application, it further includes: an ablation fiber for transmitting ablation light to obtain initial ablation light for scanning the lesion tissue; and an imaging fiber for transmitting imaging light to obtain initial imaging light for scanning the lesion tissue.

[0008] Optionally, in one embodiment of this application, the angle between the initial position of the first lens and the dichroic mirror is a first preset angle, and the axial optical axis of the first lens is consistent with the axial optical axis of the dichroic mirror.

[0009] Optionally, in one embodiment of this application, the angle between the second lens and the initial position of the MEMS galvanometer is a second preset angle, and the axial optical axis of the second lens is consistent with the axial optical axis direction of the MEMS galvanometer.

[0010] Optionally, in one embodiment of this application, the lens at the initial position of the dichroic mirror is arranged parallel to the lens at the initial position of the MEMS galvanometer, and the radial optical axis of the dichroic mirror is aligned with the radial optical axis of the MEMS galvanometer and the radial optical axis of the doublet superlens.

[0011] Optionally, in one embodiment of this application, the angle between the initial position of the dual superlens and the initial positions of the dichroic mirror and the MEMS galvanometer is a third preset angle.

[0012] A second aspect of this application provides an electronic device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement an endoscope probe based on a dual-lens telescope with adjustable focal length as described in the above embodiments.

[0013] A third aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described endoscope probe based on a dual-lens telescope with adjustable focal length.

[0014] A fourth aspect of this application provides a computer program product, including a computer program that, when executed, implements the above-described endoscope probe based on a dual-lens telescope with adjustable focal length.

[0015] This embodiment utilizes a first lens to couple the initial ablation light and a second lens to couple the initial imaging light. Based on the lesion tissue, a MEMS galvanometer reflects the imaging light, and a double-lens superlens adjusts the focal length of the imaging light. Then, a dichroic mirror scans the reflected ablation light and transmitted imaging light onto the lesion tissue, generating a scanning result. This allows for simultaneous diagnosis and treatment of lesions at different depths, achieving high-precision lesion removal and realizing integrated diagnosis and treatment. Furthermore, the focal length can be adjusted according to different distances from the lesion tissue, offering advantages such as minimally invasiveness, intelligence, and precision. This solves the problems of related technologies, which require changing probes with different focal lengths or adjusting the position of the endoscopic probe to examine tissues at different depths, resulting in cumbersome operations that affect the accuracy and efficiency of diagnosis and treatment, fail to achieve integrated diagnosis and treatment, reduce surgical efficiency, and have certain limitations in practical applications.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The following description, with reference to the accompanying drawings, describes an embodiment of the endoscopic probe based on a dual-lens telescope with adjustable focal length. Addressing the issues mentioned in the background art, such as the need to change probes with different focal lengths or adjust the position of the endoscopic probe to examine tissues at different depths, which is cumbersome, affects the accuracy and efficiency of diagnosis and treatment, and fails to achieve the goal of integrated diagnosis and treatment, thus reducing surgical efficiency and having certain limitations in practical applications, this application provides an endoscopic probe based on a dual-lens telescope with adjustable focal length. In this method, an initial ablation light is coupled using a first lens, and an initial imaging light is coupled using a second lens. Then, based on the lesion tissue, the imaging light is reflected using a MEMS galvanometer, and the focal length of the imaging light is adjusted using a dual-lens telescope. Finally, based on a dichroic mirror, the reflected ablation light and the transmitted imaging light are scanned onto the lesion tissue, generating a scanning result of the lesion tissue. This allows for simultaneous diagnosis and treatment of lesions at different depths, achieving high-precision resection of lesions and realizing the goal of integrated diagnosis and treatment. Furthermore, the focal length can be adjusted according to different distances from the lesion tissue, offering advantages such as minimally invasiveness, intelligence, and precision. This solves the problems in related technologies, such as the need to change probes with different focal lengths or adjust the position of endoscopic probes to examine tissues at different depths, which is cumbersome, affects the accuracy and efficiency of diagnosis and treatment, fails to achieve the goal of integrated diagnosis and treatment, reduces surgical efficiency, and has certain limitations in practical applications.

[0024] Figure 1 This is a block diagram of an endoscope probe based on a dual-lens telescope with adjustable focal length, provided according to an embodiment of this application.

[0025] like Figure 1 As shown, the endoscope probe 10 based on the adjustable focal length of the double superlens includes: a first lens 100, a second lens 200, a MEMS galvanometer 300, a double superlens 400, and a dichroic mirror 500.

[0026] The first lens 100 is used to couple the initial ablation light to obtain the ablation light after coupling the initial ablation light. The angle between the first lens 100 and the initial position of the dichroic mirror 500 is a first preset angle, and the axial optical axis of the first lens 100 is consistent with the axial optical axis of the dichroic mirror 500.

[0027] In some embodiments of this application, the first lens 100 can couple the ablation light transmitted through the ablation fiber into the endoscopic probe.

[0028] Furthermore, in this embodiment, the angle between the initial position of the first lens 100 and the dichroic mirror 500 is a first fixed angle, such as 45°, and is consistent with the axial optical axis of the dichroic mirror 500. This first fixed angle can be set by those skilled in the art according to actual conditions, and this application does not impose specific limitations.

[0029] The second lens 200 is used to couple the initial imaging light to obtain the coupled imaging light. The angle between the second lens 200 and the initial position of the MEMS galvanometer 300 is a second preset angle, and the axial optical axis of the second lens 200 is consistent with the axial optical axis of the MEMS galvanometer 300.

[0030] In some embodiments of this application, the second lens 200 can couple the imaging light transmitted by the imaging fiber into the endoscope probe.

[0031] Furthermore, in this embodiment, the angle between the second lens 200 and the initial position of the MEMS galvanometer 300 is a second fixed angle, such as 45°, and is consistent with the axial optical axis direction of the MEMS galvanometer 300. This second fixed angle can be set by those skilled in the art according to actual conditions, and this application does not impose specific limitations.

[0032] MEMS galvanometer 300 is used to reflect coupled imaging light based on lesion tissue to obtain reflected imaging light.

[0033] As one possible implementation method, the MEMS galvanometer 300 in this application embodiment can reflect the imaging light to obtain the reflected imaging light, and use the reflected imaging light to scan the lesion tissue.

[0034] Additionally, it should be noted that in the embodiments of this application, the MEMS galvanometer 300 has a deflection angle of ±4° in both the horizontal and vertical directions, which is controlled by a motor. The specific settings can be made by those skilled in the art according to the actual situation, and this application does not impose any specific limitations.

[0035] The dual-lens superlens 400 is used to adjust the focal length of the reflected imaging light to obtain the reflected imaging light with adjusted focal length. The angle between the initial position of the dual-lens superlens 400 and the initial positions of the dichroic mirror 500 and the MEMS galvanometer 300 is a third preset angle.

[0036] Those skilled in the art will understand that the dual superlens 400 in this application embodiment can adjust the focal length of the reflected imaging light, and then use the reflected imaging light with the adjusted focal length to obtain the scanning results of the lesion tissue.

[0037] Furthermore, in this embodiment, the angle between the initial position of the dual superlens 400 and the initial positions of the dichroic mirror 500 and the MEMS galvanometer 300 is a third preset angle, such as 45°. The specific angle can be set by those skilled in the art according to the actual situation, and this application does not impose any specific restrictions.

[0038] Additionally, it should be noted that in the embodiments of this application, the dual superlens 400 can be a focusable superlens. The focal position of the focusable superlens can be adjusted along the optical axis direction according to the change of the spacing between the dual superlenses 400. The specific settings can be made by those skilled in the art according to the actual situation, and this application does not impose any specific limitations.

[0039] For example, in this application embodiment, the dual-lens superlens 400 is divided into dual-lens superlens one and dual-lens superlens two. By controlling the magnitude of the input micro-voltage through a microcircuit, the distance between dual-lens superlens one and dual-lens superlens two is changed, thereby adjusting the focal length of the imaging light and realizing imaging of lesion tissue at different distances.

[0040] The dichroic mirror 500 is used to reflect the coupled ablation light and transmit the reflected imaging light after focal length adjustment, thus obtaining the reflected ablation light and the transmitted imaging light. These two lights are then scanned onto the lesion tissue to generate a scanning result of the lesion tissue. The lens at the initial position of the dichroic mirror 500 is parallel to the lens at the initial position of the MEMS galvanometer 300, and the radial optical axis of the dichroic mirror 500 is aligned with the radial optical axis of the MEMS galvanometer 300 and the radial optical axis of the doublet superlens 400.

[0041] In actual implementation, the color mirror 500 of Embodiment 2 of this application can reflect the coupled ablation light and transmit the reflected imaging light, thereby obtaining the reflected ablation light and the transmitted imaging light.

[0042] Furthermore, in this embodiment, the lens at the initial position of the dichroic mirror 500 is arranged parallel to the lens at the initial position of the MEMS galvanometer 300, and the radial optical axis directions of the dichroic mirror 500, the MEMS galvanometer 300, and the double superlens 400 are consistent.

[0043] Additionally, it should be noted that in this embodiment, the dichroic mirror 500 is a high-pass type, which can be deflected according to the angle of the MEMS galvanometer 300, so that the reflected ablation light ablates the lesion tissue scanned by the transmitted imaging light. Its deflection is controlled by a motor, and can be specifically set by those skilled in the art according to the actual situation. This application does not impose any specific limitations.

[0044] For example, in this embodiment, the dichroic mirror 500 is a high-pass type. Since the ablation light and imaging light have different wavelengths (the ablation light is shorter and the imaging light is longer), the dichroic mirror 500 can reflect the ablation light and transmit the imaging light. Further, in this embodiment, the initial ablation light coupled into the endoscope probe reaches the lesion tissue for ablation through reflection by the dichroic mirror 500. The initial imaging light coupled into the endoscope probe reaches the lesion tissue for imaging after reflection by the MEMS galvanometer 300, focusing by the dual-lens superlens 400, and transmission by the dichroic mirror 500. Specifically, in this embodiment, the dichroic mirror 500 and the MEMS galvanometer 300 serve as the ablation mechanism and scanning mechanism, respectively. Both change their deflection angle by controlling the input microcurrent through microcircuit, thereby reflecting the imaging light and reaching the surface of the lesion tissue for ablation and imaging.

[0045] Optionally, in one embodiment of this application, it further includes: an ablation fiber and an imaging fiber.

[0046] Among them, the ablation fiber is used to transmit ablation light to obtain the initial ablation light for scanning the lesion tissue.

[0047] In some embodiments of this application, the ablation fiber can be used to transmit ablation light, thereby obtaining the initial ablation light for scanning lesion tissue.

[0048] In this embodiment of the application, the light source for transmitting ablation light through the ablation fiber has a center wavelength of 850nm. The specific wavelength can be set by those skilled in the art according to the actual situation, and this application does not impose any specific limitations.

[0049] For example, in the embodiments of this application, since the lesion tissue has a high absorption coefficient for light at a wavelength of 850nm, it can effectively convert light energy into heat energy during ablation, and the photothermal conversion rate is relatively suitable, thereby achieving the purpose of ablation of the lesion tissue.

[0050] Imaging fiber is used to transmit imaging light to obtain the initial imaging light for scanning lesion tissue.

[0051] In some embodiments of this application, the imaging fiber can be used to transmit imaging light, thereby obtaining initial imaging light for scanning lesion tissue.

[0052] In this embodiment of the application, the center wavelength of the light source for transmitting imaging light in the imaging fiber is 1310nm. The specific wavelength can be set by those skilled in the art according to the actual situation, and this application does not impose any specific limitations.

[0053] For example, in the embodiments of this application, since the lesion tissue has relatively weak scattering of light at a wavelength of 1310nm and strong penetrating power, the interference of reflection and scattering on the tissue surface can be reduced during imaging, thus enabling imaging of deep tissues.

[0054] In summary, in this embodiment, the initial imaging light transmitted by the imaging fiber to scan the lesion tissue is coupled into the endoscope probe through the second lens 200, then reflected by the MEMS galvanometer 300, and the focal length of the reflected imaging light is determined by the double superlens 400. Finally, it is transmitted through the dichroic mirror 500 and then illuminates the lesion tissue to generate a scanning result of the lesion tissue, such as imaging of the lesion area of ​​the lesion tissue. This application does not impose specific limitations. The initial ablation light transmitted by the ablation fiber to scan the lesion tissue is coupled into the endoscope probe through the first lens 100, and then reflected by the dichroic mirror 500. According to the position of the lesion area of ​​the lesion tissue, the dichroic mirror 500 is controlled by a motor to finally make the reflected ablation light exit onto the lesion tissue for ablation. In this embodiment, by using the common optical path of the imaging light and the ablation light at the rear end of the endoscope probe, the focal length of the adjustable three-dimensional optical diagnosis and treatment is realized, which improves the efficiency and accuracy of the operation.

[0055] The following is combined with Figures 2-3 The working principle of the endoscopic probe based on the adjustable focal length of the dual superlens proposed in this application will be introduced through multiple embodiments.

[0056] in, Figure 2 This is a schematic diagram of the structure of an endoscope probe based on a dual-lens telescope with adjustable focal length according to another embodiment of this application.

[0057] Figure 3 This is a schematic diagram of the optical path of an endoscope probe with adjustable focal length based on a dual-lens superlens according to another embodiment of this application.

[0058] Among them, such as Figure 2 As shown, the endoscope probe 20 based on the adjustable focal length of the dual superlens includes: lens I 201, lens II 202, dichroic mirror 203, MEMS galvanometer 204, dual superlens 205a, dual superlens 205b, ablation fiber 206, and imaging fiber 207.

[0059] Among them, lens I 201 is used to couple the ablation light transmitted by the ablation fiber 206 into the endoscope probe; lens II 202 is used to couple the imaging light transmitted by the imaging fiber 207 into the endoscope probe; MEMS galvanometer 204 is used to reflect the imaging light and then scan the lesion tissue; dichroic mirror 203 is used to reflect the ablation light and transmit the imaging light; and double superlens 205a and double superlens 205b are used to adjust the focal length of the imaging light.

[0060] Furthermore, in this embodiment, the initial ablation light is coupled into the endoscope probe via the ablation fiber 206, and then reflected by the dichroic mirror 203 before being projected onto the lesion tissue; the initial imaging light is coupled into the endoscope probe via the imaging fiber 207; in addition, the initial imaging light transmitting the scanning lesion tissue via the imaging fiber 207 in this embodiment is coupled into the endoscope probe via the lens II 202, then reflected by the MEMS galvanometer 204, and the focal length of the reflected imaging light is determined by the double superlens 205a and double superlens 205b, and finally transmitted by the dichroic mirror 203. The dichroic mirror 203 completely transmits light of a certain wavelength while almost completely reflecting light of other wavelengths. Depending on the different wavelengths of the initial imaging light and the initial ablation light, reflection and transmission can be achieved along the same optical path.

[0061] It should be noted that in this embodiment, lens I 201 and dichroic mirror 203 are aligned on their axial optical axes; the initial positions of lens I 201 and dichroic mirror 203 are at a 45° angle; lens II 202 and MEMS galvanometer 204 are aligned on their axial optical axes; the initial positions of lens II 202 and MEMS galvanometer 204 are at a 45° angle; the radial optical axes of dichroic mirror 203, MEMS galvanometer 204, and double superlens 205 are aligned; the initial positions of double superlens 205, dichroic mirror 203, and MEMS galvanometer 204 are... Both are at 45°; the initial position of the dichroic mirror 203 is parallel to the initial position of the lens of the MEMS galvanometer 204, and its angle can be adjusted according to actual needs. Specifically, it can be set by those skilled in the art according to actual conditions, and this application does not impose specific limitations; the MEMS galvanometer 204 has a deflection angle of ±4° in both the horizontal and vertical directions, which is controlled by a motor; the dichroic mirror 203 is a high-pass type and can be deflected according to the angle of the MEMS galvanometer 204, so that the ablation light ablates the lesion tissue scanned by the imaging light, and its deflection is controlled by a motor.

[0062] In addition, in this embodiment, the center wavelength of the ablation light source transmitted by the ablation fiber 206 is 850 nm, and the center wavelength of the imaging light source transmitted by the imaging fiber 207 is 1310 nm. The dual superlens 205 can be a focusable superlens.

[0063] Combination Figure 3 As shown, the optical path of the endoscopic probe in the embodiments of this application is described.

[0064] In this embodiment, the imaging light transmitted by the imaging fiber 207 is coupled into the endoscope probe through lens II 202, then reflected by the MEMS galvanometer 204, and finally its focal length is determined by the double superlens 205. After being transmitted through the dichroic mirror 203, it illuminates the lesion tissue, generating an image of the lesion area. By changing the distance between the double superlens 205a and double superlens 205b, scanning and imaging of lesions at different distances can be achieved without moving the endoscope probe. The ablation light transmitted by the ablation fiber 206 is coupled into the endoscope probe through lens I 201, then reflected by the dichroic mirror 203. The dichroic mirror 203 is controlled by a motor according to the location of the lesion area, and finally the ablation light is emitted to the lesion tissue for ablation.

[0065] The embodiments of this application enable the imaging light and the ablation light to be perfectly matched in terms of optical path. By adjusting the distance between the double superlens 205a and the double superlens 205b, the focal length of the imaging light is changed. By controlling the dichroic mirror 203 and the MEMS galvanometer 204, the purpose of three-dimensional optical diagnosis and treatment of lesions by ablation light and imaging light can be achieved.

[0066] The endoscopic probe based on a dual-lens telescope with adjustable focal length proposed in this application can couple initial ablation light using a first lens and initial imaging light using a second lens. Then, based on the lesion tissue, the imaging light is reflected using a MEMS galvanometer. The focal length of the imaging light is adjusted using the dual-lens telescope, and the reflected ablation light and transmitted imaging light are scanned onto the lesion tissue using a dichroic mirror to generate a scanning result of the lesion tissue. This allows for simultaneous diagnosis and treatment of lesions at different depths, achieving high-precision resection of the lesion tissue and realizing the goal of integrated diagnosis and treatment. Furthermore, the focal length can be adjusted according to different distances from the lesion tissue, offering advantages such as minimally invasiveness, intelligence, and precision. This solves the problems of related technologies, which require changing probes with different focal lengths or adjusting the position of the endoscopic probe to examine tissues at different depths, resulting in cumbersome operations that affect the accuracy and efficiency of diagnosis and treatment, fail to achieve the goal of integrated diagnosis and treatment, reduce surgical efficiency, and have certain limitations in practical applications.
