[0002] The gold standard for diagnosing difficult cardiovascular diseases such as cardiomyopathy and rare cardiovascular diseases is myocardial pathology. Currently, myocardial pathology requires myocardial biopsy to obtain myocardial tissue before diagnosis. However, myocardial biopsy is an invasive interventional procedure, which requires the use of biopsy forceps to clamp 1-2 mm of myocardial tissue. 2 However, due to the uneven thickness of the cardiac chamber walls, the range of myocardial tissue that can be clamped is relatively limited, which may lead to false negatives in pathological diagnosis. In addition, there is a high risk of cardiac perforation and bleeding during the clamping process, and the patient acceptance is low, which increases the difficulty of diagnosing difficult cardiovascular diseases such as cardiomyopathy and becomes an important obstacle to the diagnosis of difficult cardiovascular diseases.

DETAILED DESCRIPTION

[0027] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0028] First embodiment

[0029] like Figures 1 to 3 As shown, the operating table 200 includes a housing 210, a control unit, a light source, a fiber coupler, a data acquisition unit and a display unit. The control unit, the light source, the fiber coupler and the data acquisition unit are arranged inside the housing 210, and the display unit is arranged on the surface of the housing 210;

[0030] The light source, the fiber optic coupler, the data acquisition unit and the display unit are connected in sequence, the control unit is connected to the light source, the fiber optic coupler, the data acquisition unit and the display unit respectively, and the fiber optic coupler is also connected to a reference mirror and an optical fiber probe 121 for scanning the myocardium respectively.

[0031] The control unit can control the opening and closing of the light source, the fiber coupler, the data acquisition unit and the display unit. The control unit controls the light source to emit incident light to the fiber coupler. When the controller 111 is executed to start the fiber optic probe 121, the fiber optic coupler serves as a connector between the light source and the optical fiber 131, so that the fiber optic probe 121 emits a measuring beam to the myocardium. At the same time, the fiber optic coupler receives the reflected measuring beam and sends the reflected measuring beam to the data acquisition unit. Finally, the display unit displays the image scanned by the fiber optic probe 121, so that medical staff can observe the different structures of the myocardium and even the distribution of different cells in real time according to the image displayed by the display unit. At this time, there is no need to perform biopsy sampling, and myocardial damage will not be caused, which greatly reduces the risks of cardiac perforation and bleeding.

[0032] refer to Figure 1The fiber coupler sends a reference beam to the reference mirror and receives the reference beam sent by the reference mirror. The control system can perform analysis based on the reference beam and the measuring beam, that is, the light source and the fiber coupler display through light interference, and integrate the signal arm and the reference arm to form an optical signal of the tissue. After the optical signal is analyzed and processed by the data acquisition unit, it is displayed in the form of a tomographic image of the tissue through the display unit, that is, the image scanned by the optical fiber probe 121.

[0033] The light source can emit broadband near-infrared light, with a central wavelength of about 1300um and a bandwidth of 40-50nm.

[0034] like Figure 1 and Figure 2 As shown, the operating table 200 further includes a drive control board, which is disposed on the surface of the housing 210 and is connected to the control unit.

[0035] Medical staff can open and close the operating table 200 according to the driving control panel, and related operations of the operating table 200 are controlled by the control unit.

[0036] like Figure 1 and Figure 2 As shown, the operating table 200 further includes a photosensitive detector, which is disposed inside the housing 210 , connected between the optical fiber coupler and the data acquisition unit, and connected to the control unit.

[0037] The photosensitive detector converts the optical signal into an electrical signal by using the photoelectric effect, and converts the light beam output by the optical fiber coupler into an electrical signal that can be collected by the data acquisition unit. The control unit can analyze and process the electrical signal that can be collected by the data acquisition unit, so that the display unit can display a clear image scanned by the optical fiber probe 121.

[0038] like Figure 2 As shown, a roller 220 is disposed at the bottom of the housing 210 , and a handle 230 is disposed at the top of the housing 210 .

[0039] The rollers 220 and the handles 230 are provided to facilitate the transportation of the operating table 200 .

[0040] Optical coherence tomography (OCT) is an imaging method using near-infrared interference. That is, the optical fiber probe 121 emits near-infrared light to scan the inside of the myocardium, and uses an interferometer to receive and record the reflected light of biological tissue components at different depths, and then processes it through a computer system to obtain a biological tissue tomographic image. The resolution of OCT can reach 10um, and the tissue penetration depth can reach 2mm. It can clearly observe the fine structure inside the tissue, so the results are highly consistent with pathological examinations, and is also called "optical biopsy."

[0041] The utility model is based on the principle of OCT, does not require biopsy sampling, will not cause myocardial damage, greatly reduces the risk of cardiac perforation and bleeding, and its penetration depth is about 2mm, which is consistent with the sampling depth of myocardial biopsy. The resolution of OCT is micron-level, and different structures of the myocardium and even the distribution of different cells can be observed in real time.

[0042] Second embodiment

[0043] like Figures 2 to 4 As shown, the myocardial imaging device includes the operating table 200 of the first embodiment, and the myocardial biopsy device also includes a fusion catheter 100, a controller 111 and an optical fiber probe 121, the controller 111 is connected between the proximal end of the fusion catheter 100 and the operating table 200, the optical fiber probe 121 is arranged at the distal end of the fusion catheter 100, an optical fiber 131 is arranged in the fusion catheter 100, the optical fiber 131 is connected between the optical fiber probe 121 and the controller 111, and a control button for controlling the opening and closing of the optical fiber probe 121 is arranged on the controller 111.

[0044] The optical fiber probe 121 is arranged at the distal end of the fusion catheter 100, and the controller 111 is arranged at the proximal end of the fusion catheter 100. The optical fiber probe 121 is controlled to open and close by the controller 111, so as to transmit the light source generated by the operating table 200 to the optical fiber probe 121, and the optical fiber probe 121 emits near infrared rays to scan the inside of the myocardium. The distal end of the fusion catheter 100 is inserted into the heart cavity of the patient, and the proximal end of the fusion catheter 100 is located outside the body cavity of the patient to operate the controller 111. It can be seen that by scanning the inside of the myocardium in real time through the optical fiber probe 121, different structures of the myocardium and even the distribution of different cells can be observed in real time.

[0045] The optical fiber probe 121 can emit broadband near-infrared rays to scan the inside of the myocardium, with a central wavelength of about 1300um and a bandwidth of 40-50nm.

[0046] like Figure 3As shown, a bend 100a is provided on the outer wall of the distal end of the fused catheter 100, a drive cable 133 is provided inside the fused catheter 100, the drive cable 133 is connected between the bend 100a and the controller 111, and a control button for controlling the bending of the bend 100a of the fused catheter 100 is provided on the controller 111.

[0047] The fusion catheter 100 is made of a flexible material to achieve the bending of the fusion catheter 100. The distal end of the fusion catheter 100 can be controlled to bend, and the optical fiber probe 121 can bend along with the bending of the distal end of the fusion catheter 100, thereby increasing the use function.

[0048] like Figure 2 and Figure 3 As shown, the proximal end of the fused catheter 100 is connected with a flushing catheter 113. The flushing catheter 113 is respectively connected between the contrast agent and the proximal end of the fused catheter 100, so that the contrast agent can enter the fused catheter 100 and be ejected from the distal end of the fused catheter 100 to flush the blood on the myocardial surface, thereby improving the clarity of the optical fiber probe 121 scanning the myocardium.

[0049] refer to Figure 3 The fusion catheter 100 is divided into an optical fiber passage 1001 and a flushing passage 1002 from the inside to the outside. The optical fiber probe 121 and the optical fiber 131 are arranged in the optical fiber passage 1001, and the flushing catheter 113 is connected to the flushing passage 1002.

[0050] It can be seen that the optical fiber probe 121 and the contrast agent are respectively arranged in different passages, and are transported and controlled separately.

[0051] After puncturing the femoral vein, the operator delivers the fusion catheter 100 to the right heart system, i.e., the right atrium and right ventricle, or delivers the imaging catheter to the left heart system, i.e., the left atrium and left ventricle, through puncturing the radial artery or femoral artery. Then, after the optical fiber probe 121 is delivered to the vicinity of the myocardium to be observed through the fusion catheter 100, the contrast agent is injected with the flushing catheter 113 to flush the surface of the myocardium. After the optical fiber probe 121 is attached to the observed myocardium, the near-infrared light emission is controlled by the controller 111, and the myocardial tissue structure can be observed in real time through the display unit of the operating console 200, and a diagnosis can be made for the observed myocardium based on the characteristics of the myocardial tissue structure, and the structural image of the observed myocardium can be saved.

[0052] Third embodiment

[0053] like Figure 2 , Figure 5 and Figure 6As shown, the myocardial imaging device of the third embodiment is different from the second embodiment in that the myocardial imaging device further includes a biopsy forceps handle 112 and a biopsy forceps 122, which can perform myocardial biopsy.

[0054] The biopsy forceps 122 are arranged at the distal end of the fusion catheter 100, and the biopsy forceps handle 112 is arranged at the proximal end of the fusion catheter 100. A control line 132 is arranged inside the fusion catheter 100, and the control line 132 is connected between the biopsy forceps handle 112 and the biopsy forceps 122. An operation button for operating the biopsy forceps 122 to open and close is arranged on the biopsy forceps handle 112.

[0055] The biopsy forceps 122 is arranged at the distal end of the fusion catheter 100, and the biopsy forceps handle 112 is arranged at the proximal end of the fusion catheter 100. The biopsy forceps 122 is controlled to open and close by the biopsy forceps handle 112. The distal end of the fusion catheter 100 is inserted into the patient's heart cavity, and the proximal end of the fusion catheter 100 is located outside the patient's body cavity, so as to operate the controller 111 and the biopsy forceps handle 112. The optical fiber probe 121 can scan the inside of the myocardium, and the biopsy forceps 122 clamps the myocardial tissue. It can be seen that the optical fiber probe 121 scans the inside of the myocardium in real time. After determining the myocardium that needs to be biopsied, the biopsy forceps handle 112 can be operated to make the biopsy forceps 122 clamp the myocardial tissue that needs to be biopsied, and the clamping position, clamping depth, and whether to repeat the clamping can be directly and real-time judged, thereby avoiding serious complications such as empty clamping, wrong clamping, and even heart rupture, thereby improving the success rate of myocardial biopsy.

[0056] The fusion catheter 100 is divided into an optical fiber passage 1001 , a flushing passage 1002 , and a clamp passage 1003 from the inside to the outside. The biopsy forceps 122 and the steering wire 132 are arranged in the clamp passage 1003 .

[0057] It can be seen that the optical fiber probe 121 and the biopsy forceps 122 are respectively arranged in different passages, so as to prevent the optical fiber 131 and the control line 132 from being in the same passage, thereby preventing the optical fiber 131 and the control line 132 from being entangled or even unable to operate.

[0058] like Figure 5 and Figure 6As shown, the biopsy forceps 122 includes two clamps 1221, which are arc-shaped, surround the outer side of the optical fiber probe 121, and are arranged at intervals, one of the clamps 1221 is connected to the control line 132, and the biopsy forceps handle 112 pulls and releases the control line 132 to change the angle between the clamp 1221 and the other clamp 1221, thereby completing the opening and closing of the biopsy forceps handle 112. When the biopsy forceps handle 112 is closed, myocardial tissue can be clamped.

[0059] Further, refer to Figure 5 The biopsy forceps 122 further includes a connecting rod 1222, and the two clamps 1221 are divided into an upper clamp and a lower clamp, and the lower clamp is connected to the control line 132, wherein the upper clamp is fixedly connected to the connecting rod 1222, and the lower clamp is rotatably connected to the connecting rod 1222. When the control line 132 is operated and pulled by the biopsy forceps handle 112, the lower clamp and the upper clamp are closed or opened. Figure 5 The connecting rod 1222 passes through the wall between the optical fiber passage 1001 and the clamp passage 1003 and is fixed inside the fusion catheter 100 .

[0060] As can be seen from the above, optical coherence tomography OCT uses near-infrared light interference imaging, that is, the optical fiber probe 121 emits near-infrared rays to scan the inside of the myocardium, and uses an interferometer to receive and record the reflected light of biological tissue components at different depths, and then processes it through a computer system to obtain a biological tissue tomographic image. The resolution of OCT can reach 10um, and the tissue penetration depth can reach 2mm, so that the fine structure inside the tissue can be clearly observed. OCT can not only detect abnormal myocardial tissue in real time and improve the positive detection rate of biopsy, but also determine the thickness and structure of the myocardium to be biopsied, and prevent the occurrence of complications such as cardiac perforation or mis-clamping of normal heart structures such as valves.

[0061] OCT, also known as "optical biopsy", can help the surgeon observe the structure of the heart and myocardium in real time due to its penetration depth and resolution, and guide the surgeon to truly target and clamp the myocardial tissue that requires pathological biopsy during myocardial biopsy. At the same time, through clear and real-time images, the surgeon can avoid clamping too thin myocardium, prevent heart perforation, and avoid accidentally clamping valves, blood vessels, conduction bundles and other tissue structures.

[0062] The biopsy route can be selected according to the biopsy site. For example, the biopsy of the left ventricle and left atrium can reach the left heart system through radial artery puncture or femoral artery puncture; the biopsy of the right atrium and right ventricle can reach the right heart system through the femoral vein. After operating the fusion catheter 100 to reach the vicinity of the myocardium to be biopsied, the contrast agent is injected into the flushing catheter 113 to flush the myocardial surface. After the optical fiber probe 121 is attached to the observed myocardium, the optical fiber probe 121 is controlled by the controller 111 to emit near-infrared light. The myocardial tissue structure can be observed in real time and in a positioned manner through the display unit of the operating table 200. After the myocardium to be biopsied is determined, the biopsy forceps handle 112 connected to the biopsy forceps 122 is operated to clamp the myocardial tissue.

[0063] The embodiments described above are only used to illustrate the technical ideas and features of the utility model, and their purpose is to enable technicians in this field to understand the content of the utility model and implement it accordingly. The patent application scope of the utility model cannot be limited only by this embodiment, that is, any equivalent changes or modifications made according to the spirit disclosed by the utility model still fall within the patent scope of the utility model.
