Description

Technical Field

[0001] This disclosure relates to the field of cardiovascular diagnostic and therapeutic equipment technology, and more specifically, to a diagnostic and therapeutic device. Background Technology

[0002] Optical coherence tomography (OCT) is an imaging measurement method where OCT light is guided onto an object, especially human tissue, and the scattering center of the object is inferred from the reflected light. The object light rays reflected back from the object are then superimposed with reference light rays. Image information is obtained by evaluating the interference signal of the two light rays. Lesions are diagnosed based on the acquired image information. In related technologies, for cardiovascular fields such as coronary arteries and atherosclerosis, after OCT diagnosis, additional laser treatment equipment is needed to treat the lesions, resulting in multiple diagnostic and treatment steps and low efficiency.

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the component itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0020] In related technologies, for cardiovascular diseases such as coronary arteries and atherosclerosis, diagnosis requires OCT followed by additional laser treatment equipment to treat the lesions, resulting in cumbersome and inefficient diagnostic and treatment procedures.

[0021] To solve the above technical problems, such as Figures 1-8 As shown, this disclosure provides a diagnostic and treatment device, including: a diagnostic and treatment module 1 and a first lens assembly 2 spaced apart from the diagnostic and treatment module 1, wherein the diagnostic and treatment module 1 includes an OCT module 11 and a laser module 12, and the first lens assembly 2 includes a first lens body 21, the first lens body 21 having a first reflective surface 22 in the shape of a cone ring in the circumferential direction, the first reflective surface 22 being used to receive the light emitted from the OCT module 11 or the laser module 12 and guide the light to be reflected to the area to be examined.

[0022] Through the above technical solution, the diagnostic and treatment equipment includes a diagnostic and treatment module 1 and a first lens assembly 2. The diagnostic and treatment module 1 includes an OCT module 11 and a laser module 12. The first lens assembly 2 includes a first lens body 21, on which a first reflective surface 22 in the shape of a conical ring is provided. This allows light from the OCT module 11 to be transmitted through the conical ring and reflected through the first reflective surface 22 to diagnose the area to be examined, and light emitted from the laser module 12 to be transmitted through the first reflective surface 22 to treat the area to be examined. This integrates OCT diagnosis and laser treatment, achieving a unified approach to diagnosis and treatment and improving the efficiency of diagnosis and treatment. Furthermore, the conical shape of the first reflective surface 22 simplifies the diagnostic and treatment process.

[0023] It should be noted that only one of the OCT module 11 and laser module 12 can be used; that is, diagnosis and treatment are performed separately. The OCT module 11 may include a light source module, which can be a near-infrared light source with a wavelength of 840nm, 1060nm, or 1310nm, balancing tissue penetration depth (reducing hemoglobin absorption) and resolution (short coherence length). The laser module 12 can use ultraviolet light, for example, with a wavelength of 308nm or 355nm. The light emitted by the OCT module 11 and laser module 12 is arranged circumferentially around the first lens body 21, meaning the light rays are arranged in a ring around the central axis of the first lens body 21, thereby forming a ring-shaped diagnostic or treatment area.

[0024] Of course, the aforementioned diagnostic and treatment equipment also includes other essential components. For example, the diagnostic and treatment equipment also includes an endoscopic probe 50, an interferometer, a high-speed detector, a high-speed data acquisition and processing module, a guidewire, a catheter sheath, a control console, and a power supply. The first lens assembly 2 is housed within the endoscopic probe 50, which can be housed within a catheter sheath. The probe penetrates deep into the blood vessel through the catheter sheath. The guidewire works in conjunction with the catheter sheath to guide the probe to the lesion site. The blood vessel can be a coronary artery or a peripheral blood vessel. The first lens assembly 2 is integrated into the endoscopic probe 50 to receive and reflect the light emitted by the light source module to obtain a cross-sectional image of the blood vessel. Simultaneously, the endoscopic probe 50 is designed to advance along the axial direction of the blood vessel to obtain a three-dimensional image along its long axis. The interferometer splits the light emitted by the OCT module 11 into two paths: a reference light (returning after passing through the first lens assembly 2) and a sample light (entering the blood vessel tissue through the probe). When the path difference between the two paths is within the coherence length of the light source, the interference signal carries tissue depth information. The high-speed data acquisition and processing module may include a balanced detector and a high-speed ADC (Analog-to-Digital Converter). The system includes an analog-to-digital converter (ADC), an FPGA (Field-Programmable Gate Array), and a motion artifact correction algorithm. A balanced detector is used to suppress strong background noise from blood scattering and improve the signal-to-noise ratio of weak signals from the vessel wall. A high-speed ADC and FPGA are used to acquire spectral signals in real time, supporting real-time imaging under dynamic vascular motion. The motion artifact correction algorithm compensates for periodic vascular displacement caused by heartbeats through phase correlation analysis between adjacent frames. The control console integrates the light source, detector, signal processing unit, and software, while the power supply provides stable power to the light source and detector.

[0025] It is understandable that the interferometer, high-speed detector, high-speed data acquisition and processing module, guidewire, catheter sheath, control console, and power supply in the aforementioned diagnostic and treatment equipment can also be components from existing technologies. The light emitted by the aforementioned OCT module 11 and laser module 12 is arranged circumferentially around the first lens body 21, that is, the light is incident in a ring shape with the central axis of the first lens body 21 as the ring, thereby forming a ring-shaped diagnostic or treatment area, eliminating the need to rotate the corresponding endoscopic probe and simplifying the diagnostic and treatment process.

[0026] Endoscopic probes in related technologies typically include phased array MENS lenses, which acquire images of cross-sectional blood vessels through rotation. The endoscopic probe 50 provided in the embodiments of this application can be referenced from... Figure 9 and Figure 10 As shown, a first reflective surface 22 in the shape of a cone is provided circumferentially on the first lens body 21, which can replace the above-mentioned rotation method to obtain images of the blood vessel cross-section. By sequentially guiding the light from multiple OCT modules onto the first reflective surface 22, images of the blood vessel cross-section can be obtained. Of course, in order to obtain three-dimensional imaging of the blood vessel, the first lens assembly 2 can also be driven to move along the axial direction of the blood vessel to obtain three-dimensional imaging in the long axis direction of the blood vessel, thereby completing the diagnosis of the blood vessel. Of course, after the diagnosis is completed, the light source can be switched, that is, the OCT module 11 is turned off and the laser module 12 is turned on. The light from the laser module 12 passes through the first reflective surface 22 to treat the lesion area.

[0027] To expand the scope of diagnosis and treatment, in some feasible embodiments, the diagnostic and treatment device further includes a second lens assembly 3. The second lens assembly 3 includes a second lens body 31, which is cylindrical and fitted around the outer periphery of the first lens assembly 2. The inner wall of the second lens body 31 has an annular second reflective surface 32 opposite to the first reflective surface 22. The second reflective surface 32 receives light reflected from the first reflective surface 22 and reflects it to the area to be examined. Thus, because the second lens body 31 is cylindrical and fitted around the outer periphery of the first lens assembly 2, and its inner wall has an annular second reflective surface 32 corresponding to the first reflective surface 22, the light emitted by the OCT module 11 or the laser module 12 can pass through the first reflective surface 22 and the second reflective surface 32, thereby changing the original light transmission direction and expanding the scope of diagnosis and treatment.

[0028] In some feasible embodiments, the diameter of the annular second reflective surface 32 at various positions along the axial direction gradually increases from the first end to the second end of the second lens body 31. The second end is the exit end of the light emitted from the OCT module 11 or the laser module 12. The light emitted by the OCT module 11 or the laser module 12 can first pass through the first reflective surface 22 and then be reflected to the second reflective surface 32 and guided to the area to be detected. Since the diameter of the second reflective surface 32 gradually increases from the first end to the second end of the second lens body 31, the second reflective surface 32 can be flared in the direction of light transmission. The flared second reflective surface 32 can increase the illumination range of the light, thereby expanding the scope of diagnosis and treatment and improving the efficiency of diagnosis and treatment.

[0029] In some feasible embodiments, the second reflecting surface 32 has a generatrix that forms a circumferential ring around the second reflecting surface 32, the generatrix extending in an arc; or, the generatrix extending in a straight line; or, the generatrix extending in a zigzag line. The generatrix segment of the frustum-shaped cone surface here can be referenced. Figures 4 to 7 The line segment referred to by L in the diagram. For example, the generatrix is ​​composed of multiple straight line segments, namely, multiple sequentially connected first straight line segments 33, second straight line segments 34, and third straight line segments 35. The slope of the first straight line segments 33, second straight line segments 34, and third straight line segments 35 gradually increases from the first end to the second end of the second lens body 31. In this way, the light rays passing through the first reflecting surface 22 can selectively be reflected through the first straight line segments 33, second straight line segments 34, and third straight line segments 35 to the area to be inspected. As the slope of the first straight line segments 33, second straight line segments 34, and third straight line segments 35 gradually increases, the detection range of the light rays passing through the first straight line segments 33, second straight line segments 34, and third straight line segments 35 gradually expands, eventually forming a ring-shaped detection area, thereby expanding the scope of diagnosis and treatment and improving the efficiency of diagnosis and treatment.

[0030] Of course, in some feasible methods, the busbar extends in an arc, such as... Figure 7 As shown, the arc extends from the first end of the second lens body 31 toward the second end, and the slope of the tangent corresponding to the arc segment gradually increases. As a result, the light reflected from the first reflecting surface 22 can gradually expand the detection range through the second reflecting surface 32, thereby improving the efficiency of diagnosis and treatment.

[0031] In some feasible embodiments, to further improve the efficiency of diagnosis and treatment, the first lens assembly 2 and / or the second lens assembly 3 are configured to be movable relative to each other along the axial direction. For example, the first lens assembly 2 is configured to be movable along the axial direction, which can be referred to as the X direction in the figure. The second lens assembly 3 is fitted around the outer periphery of the first lens assembly 2. Thus, by moving axially individually, the light emitted by the OCT module 11 or the laser module 12 can be reflected by the first reflecting surface 22 on the first lens body 21 and then reflected by the second reflecting surface 32 on the second lens body 31 to the area to be inspected. Since the cross-section of the second reflecting surface 32 gradually increases from the first end to the second end of the second lens body 31, the second reflecting surface 32 can be made to be flared in the direction of light transmission. In this way, the detection range gradually expands, eventually forming a ring-shaped detection area, thereby expanding the scope of diagnosis and treatment and improving the efficiency of diagnosis and treatment.

[0032] Of course, the above-described embodiment in which the first lens assembly 2 is configured to move along the axial direction is illustrative. In other embodiments, the second lens assembly 3 can also be configured to move along the axial direction. In this way, the light emitted by the OCT module 11 or the laser module 12 can be reflected to the area to be inspected after passing through the first reflecting surface 22 on the first lens body 21 and then through the second reflecting surface 32 on the second lens body 31. Since the cross-section of the second reflecting surface 32 gradually increases from the first end to the second end of the second lens body 31, the second reflecting surface 32 can be made to be flared in the direction of light transmission. In this way, the detection range gradually expands and eventually forms a ring-shaped detection area, thereby expanding the scope of diagnosis and treatment and improving the efficiency of diagnosis and treatment.

[0033] To facilitate the axial movement of the first lens assembly 2 and / or the second lens assembly 3, in some feasible embodiments, the diagnostic and therapeutic device further includes a drive mechanism 4 configured to selectively drive the first lens assembly 2 and / or the second lens assembly 3 axially. For example, the drive mechanism 4 may include a first connecting rod 41, a second connecting rod 42, and a drive element (not shown in the figure). The drive element may be a linear motor or a lead screw assembly. The first connecting rod 41 is fixedly connected to a first end of the first lens body 21. A receiving groove may be provided on the end face of the first connecting rod 41 opposite to the first lens body 21, and the first end of the first lens body 21 can be fixed in the receiving groove. The second connecting rod 42 is fixedly connected to a first end of the second lens body 31. The connection method between the second connecting rod 42 and the second lens body 31 can refer to the connection method between the first connecting rod 41 and the first lens body 21. The second end of the first connecting rod 41 and / or the second end of the second connecting rod 42 is connected to the drive element. For example, the first lens assembly 2 is configured to move along the axial direction, while the second lens assembly 3 is configured to remain stationary. The driving component can be a linear motor, and the output end of the driving component is connected to the first connecting rod 41. For example, the first connecting rod 41 can be fixedly connected to the output end of the driving component by bolts. In this way, the driving component can push the first connecting rod 41 to move along the axial direction, so that the reflected light rays passing through the first reflecting surface 22 on the first lens body 21 are reflected by the second reflecting surface 32 at different positions in the second lens body 31 as the first lens body 21 moves axially. This forms a ring-shaped diagnostic and treatment area, expands the scope of diagnosis and treatment, and improves the efficiency of diagnosis and treatment. Of course, the second lens assembly 3 can be configured to move along the axial direction, while the first lens assembly 2 is configured to remain stationary. The driving component can be a linear motor, and the output end of the driving component is connected to the second connecting rod 42. In this way, the driving component can push the second connecting rod 42 to move along the direction, so that the reflected light rays passing through the first reflecting surface 22 on the first lens body 21 are reflected by the second reflecting surface 32 at different positions in the second lens body 31 as the second lens body 31 moves axially, thereby forming a ring-shaped diagnostic and treatment area, expanding the scope of diagnosis and treatment, and improving the efficiency of diagnosis and treatment.

[0034] It is understood that the above-described implementation of driving the first lens assembly 2 and the second lens assembly 3 separately is illustrative. In other implementations, the driving component may also include a first driving component and a second driving component, wherein the first driving component is connected to the first lens assembly 2 and the second driving component is connected to the second lens assembly 3, thereby controlling the relative axial movement of the first lens assembly 2 and the second lens assembly 3. This allows the reflected light rays passing through the first reflecting surface 22 on the first lens body 21 to be reflected by the second reflecting surface 32 at different positions in the second lens body 31 as the first lens body 21 and the second lens body 31 move axially, thereby expanding the scope of diagnosis and treatment and improving the efficiency of diagnosis and treatment.

[0035] Of course, in some feasible ways, the driving member can also drive the second lens assembly 3 to move axially on its own, that is, the driving member drives the second connecting rod 42 to move axially, so that the reflected light rays passing through the first reflecting surface 22 on the first lens body 21 can be reflected by the second reflecting surface 32 at different positions in the second lens body 31 as the first lens body 21 moves axially, thereby expanding the scope of diagnosis and treatment and improving the efficiency of diagnosis and treatment.

[0036] In some feasible ways, such as Figure 8 As shown, to facilitate light transmission, the diagnostic and treatment device also includes an optical fiber assembly 13. This optical fiber assembly is disposed between the diagnostic and treatment module 1 and the first lens assembly 2. Multiple optical fiber assemblies 13 are arranged at circumferential intervals along the first lens assembly 2. The optical fiber assemblies 13 are used to transmit light emitted from the OCT module 11 and the laser module 12 and guide the light to the first reflecting surface 22 of the first lens assembly 2. For example, the optical fiber assembly 13 may include multiple optical fibers, with at least some fibers used to transmit light emitted by the OCT module 11 and the remaining fibers used to transmit light emitted by the laser module 12.

[0037] Of course, to facilitate light transmission and avoid interference between the light emitted by the OCT module 11 and the laser module 12, the fiber optic assembly 13 includes a first fiber 14 and a plurality of second fibers 15 arranged in a circumferential ring around the first fiber. The first fiber 14 is used to transmit the light emitted by the OCT module 11, and the second fibers 15 are used to transmit the light emitted by the laser module 12. Thus, when diagnosis is required, the light emitted by the OCT module 11 is guided through the first fiber 14 to the first reflecting surface 22 of the first lens assembly 2, and then diagnoses the area to be examined through the second reflecting surface 32 of the second lens assembly 3. After the diagnosis is completed, the diagnostic and treatment device is moved to the area to be treated. At this time, the OCT module 11 is turned off and the laser module 12 is turned on. The light emitted by the laser module 12 is guided through the second fibers 15 to the first reflecting surface 22 of the first lens assembly 2, and then treats the area to be treated through the second reflecting surface 32 of the second lens assembly 3.

[0038] Of course, the structure of the first optical fiber 14 with multiple second optical fibers 15 arranged in an axial ring is illustrative. In other embodiments, the arrangement can be made according to the specific working conditions.

[0039] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0041] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
