Description

Imaging Probes and Medical Endoscopes {IMAGING PROBE AND MEDICAL ENDOSCOPE}

The present invention relates to imaging probes and medical endoscopes.

The imaging probe is an optical element inserted into a channel of a commercially available medical endoscope to guide the imaging light inside the living body, and the display module may convert the imaging light guided through the imaging probe to reproduce a fluorescence image or a high resolution image.

Imaging probes can be made very small, less than 1 mm in diameter. Such microscopic micro-imaging probes have a wide range of applications in various clinical fields such as gastroenterology, urology, otolaryngology, ophthalmology, cardiovascular and neurosurgery.

On the other hand, when acquiring accurate diagnosis and high resolution images in vivo, the shaking of the subject (subject) due to heartbeat or swelling contraction of the pleura limits the image quality (optically unstable image is obtained). There is a problem in that the disease cannot be precisely diagnosed due to deterioration of image quality.

In particular, in a super resolution imaging system that overcomes the optical diffraction limit, the shaking of a specimen (subject) has a greater effect on the deterioration of the image quality, and thus a method of correcting it is required.

Hereinafter, the endoscope 1000 of the first embodiment will be described with reference to the drawings. 1 is a conceptual diagram showing the endoscope of the present invention, Figure 2 is a perspective view showing a part of the endoscope of the first embodiment of the present invention. The endoscope 1000 of the first embodiment may include the covering tube 100, the imaging probe 200, the suction member 300, the manipulation member 500, and the display module 600.

The cladding tube 100 may be a member of a substantially elastic cylindrical form. The length of the covering tube 100 may be formed extending from the front to the rear. The operation member 500 may be disposed in the middle of the coating tube 100. The imaging probe 200 may be disposed inside the coating tube 100. The cladding tube 100 may protect the imaging probe 200 from an external environment. Therefore, at least part of the covering tube 100 may be made of an insulating material, and may be made of an optically opaque material.

The covering tube 100 has a first surface 110 forming a front surface, a second surface 120 extending rearward from the first surface 110 to form an outer surface, and a first surface 110. It may include an imaging probe channel 130 extending rearward to form an internal space.

The imaging probe 200 may guide the imaging light of a specimen located inside the biological tissue to the display module 600. That is, the imaging probe 200 forms an optical system and may be optically connected to the display module 600. The length of the imaging probe 200 may extend from front to back.

Imaging probe 200 may be disposed in imaging probe channel 130 of cladding tube 100. In this case, the imaging probe 200 may slide forward and backward (lengthwise). As the imaging probe 200 moves forward, the angle of view (FOV) may be narrowed (Narrow), and as the imaging probe 200 moves backward, the angle of view may be widened (Wide). Therefore, the user may adjust the position of the imaging probe 200 according to the angle of view of the image to be photographed.

Depending on the position of the imaging probe 200, the front portion of the imaging probe 200 may be an open portion of the first surface 110 of the coating tube 100 formed by the imaging probe channel 130 of the coating tube 100. It may be exposed to the outside through the built-in imaging probe channel 130 of the coating tube 100 may not be exposed to the outside.

The imaging probe 200 may include an exterior member 210, an optical element 220, and a protection window 230.

The protection window 230 may be disposed in front of the optical device 200. The protection window 230 may cover the opening located in front of the exterior member 210 to protect the optical device 220. Thus, the protection window 230 may be referred to as a "cover glass." In addition, at least a portion of the protect window 230 may be formed of an optical transparent material so that the imaging light of the specimen may pass through the protect window 230. Therefore, the imaging light of the specimen may be irradiated to the optical device 220 through an open portion positioned in front of the protection window 230 and the exterior member 210. As a result, the endoscope 1000 of the first exemplary embodiment may photograph a sample located approximately in front of the imaging probe 200.

The suction member 300 may be attached to the living tissue. That is, the suction member 300 may be attached to the specimen and / or the biological tissue adjacent to the specimen, and may connect the imaging probe 200 and the specimen and the biological tissue adjacent to the specimen like a single member. Therefore, the suction member 300 can reduce the shaking of the sample due to the biological activity, and can prevent the image quality of the captured image from being degraded by the shaking of the sample.

When the suction member 300 is attached, the suction member 300 may suck at least a portion of the sample and the biological tissue adjacent to the sample. For example, the suction member 300 may include a plurality of suction cups 310, and the specimen may be formed by the material of the suction cup 310 (for example, an elastic material such as rubber) and structural features. At least a portion of the biological tissue adjacent to the sample may be sucked toward the suction member 300.

The suction member 300 may be disposed in front of the covering tube 100. The suction member 300 may be disposed to face forward. Therefore, the suction member 300 may be attached to the biological tissue located in front of the imaging probe 200. The suction member 300 may be disposed on the first surface 110 of the covering tube 100. In this case, the suction member 300 may be disposed to be spaced apart from the open portion of the first surface 110 of the covering tube 100 formed by the imaging probe channel 130. Therefore, the forward and backward sliding movement of the imaging probe 200 may not be interfered by the suction member 300.

The operation member 500 may be disposed in the middle of the covering tube 100. The manipulation member 500 may manipulate the imaging probe 200 to slide in the front-rear direction. On the other hand, the endoscope 1000 of the first embodiment may be added to a variety of functions (for example, a suction channel is formed to suck foreign matter), these various functions can be operated by the operation member 500.

The display module 600 may convert the imaging light of the specimen delivered through the imaging probe 200 to reproduce the image. Accordingly, the display module 600 may include an image sensor for converting an optical signal into an RGB electronic signal, and a display panel electrically connected to the image sensor to convert the RGB electronic signal into an image. On the other hand, the display module 600 is not limited thereto. The display module 600 may use any kind of device capable of converting the imaging light guided by the imaging probe 200 to the naked eye. For example, the display module 600 may be an optical microscope or a super resolution imaging system having an ultra high resolution that overcomes an optical diffraction limit.

Second Embodiment

This second embodiment has substantially the same technical features as the first embodiment except that the arrangement and structure of the suction member 300 are changed in comparison with the first embodiment. Therefore, the technical features of the first embodiment may be analogically applied to the second embodiment. In describing the second embodiment, descriptions of technical features substantially the same as those of the first embodiment will be omitted.

Hereinafter, the endoscope 1000 of the second embodiment will be described with reference to the drawings. 3 is a perspective view showing a part of the endoscope of the second embodiment of the present invention. The endoscope of the second embodiment may include the covering tube 100, the imaging probe 200, the suction member 300, the operation member 500, and the display module 600, similarly to the endoscope of the first embodiment. .

The suction member 300 of the second embodiment may be disposed in the imaging probe 200. Therefore, the suction member 300 may be a component included in the imaging probe 200. In this case, the suction member 300 may be disposed in front of the exterior member 210 of the imaging probe 200, and at least a portion (front part) may be exposed to the exterior of the exterior member 210. That is, in the imaging probe 200 of the second embodiment, the protection window 230 is omitted, and the suction member 300 is disposed in place.

Therefore, at least a portion of the suction member 300 may be formed of an optical transparent material so that the imaging light of the specimen may pass therethrough. In addition, the suction member 300 may be disposed to be forward and attached to a living tissue positioned in front of the imaging probe 200. To this end, the suction member 300 may include a single suction cup 310. However, the suction member 300 of the second embodiment is not limited thereto. According to the design request, the suction member 300 of the second embodiment may include a plurality of suction cups.

In summary, the suction member 300 of the second embodiment may cover the front of the exterior member 210 to protect the optical element 220 (perform a cover glass function), and adhere to and reproduce the living tissue. It is also possible to improve the image quality of the video to be performed (perform fixed).

Furthermore, in the second embodiment, since the suction member 300 and the optical element 220 of the imaging probe 200 are formed to be aligned in the front-back direction (the center of the suction member may coincide with the optical axis of the optical element), The biological tissue fixed by the suction member 300 may be taken as a specimen. Therefore, the image played by the display module 600 may be further stabilized.

Meanwhile, a surplus space may be formed on the first surface 110 of the covering tube 100 by the member of the suction member 300. By utilizing this, a plurality of surplus channels 140 may be formed. The surplus channel 140 may be a channel for absorbing foreign substances, a channel in which an optical fiber equipped with a narrow band imaging (NBI) filter is disposed, or a channel for irradiating biological tissue with a specific bandwidth of light. As a result, an image-enhanced endoscope capable of performing various functions may be implemented.

Hereinafter, a modification of the second embodiment will be described with reference to this drawing. In the modification of the second embodiment, the arrangement and structure of the suction member 300 are changed. 4 is a perspective view showing a part of the endoscope of the modification of the second embodiment of the present invention.

The suction member 300 of the modified example of the second embodiment may be disposed on an outer surface of the exterior member 210 of the imaging probe 200. In this case, at least a portion of the suction member 300 may be exposed to the outside from the exterior member 210 of the imaging probe 200. That is, at least a portion of the suction member 300 may be exposed and disposed on the side of the imaging probe 200. In this case, the suction member 300 may be disposed toward the side. In addition, the suction member 300 may include one or more suction cups 310. One or more suction cups 310 may be spaced apart from each other. In this case, one or more suction cups 310 may be spaced apart in the front-rear direction. In addition, as in the first embodiment, at least a portion of the front of the exterior member 210 may be opened, and a protection window 230 may be disposed in front of the exterior member 210.

Therefore, the suction member 300 may be attached to the biological tissue facing the outer surface of the outer member 210 of the imaging probe 200. Since the imaging probe 200 photographs the biological tissue located in front, it may be necessary to attach the imaging probe 200 to the biological tissue facing the outer surface of the exterior member 210 in some cases. Prevent deformation by members). For example, the endoscope of the modified example of the second embodiment may be used when the imaging probe 200 is attached to the latitude, and the inside of the stomach located in front of the latitude is photographed.

Hereinafter, another modification of the second embodiment of the present invention will be described. 5 is a cross-sectional view showing an imaging probe and a suction member of another modification of the second embodiment of the present invention.

The imaging probe 200 may further include a light guide element 230. The light guide element 230 may be disposed inside the exterior member 210 and may be disposed in front of the optical element 220. In this case, if there is no need to guide light forward by design request, the front open portion of the exterior member 210 can be closed. That is, unlike the modification of the second embodiment, the "protect window" may be omitted, and instead, a cover cap 210-1 to be described later may be added.

The light guide element 230 may be a “reflection prism”. However, the light guide element 230 of the modification of the second embodiment is not limited thereto. For example, the light guide element 230 may be various kinds of reflective mirrors, or may be an optical lens or a lens array. That is, the light guide element 230 may optically connect the suction member 300 and the optical element 220 by at least one of reflection or refraction.

The reflective surface (or refractive surface) of the light guide element 230 may face the suction member 300. At the same time, the reflective surface (or refractive surface) of the light guide element 230 may face the surface located in front of the optical element 220.

In more detail, the imaging light of the biological tissue facing the outer surface of the exterior member 210 of the imaging probe 200 passes through the suction member 300 and moves to the light guide element 230. The light may be reflected (or refracted) by 240 to move to the optical device 220, and may move to the display module 600 through the optical device 220. Through the optical path, the display module 600 may reproduce an image of biological tissue positioned to face the outer surface of the imaging probe 200.

Meanwhile, the exterior member 210 may further include a cover cap 210-1. The cover cap 210-1 may be disposed in front of the exterior member 210.

The light guide element 240 may be disposed inside the cover cap 210-1, and the light guide element 240 may be disposed in front of the optical element 220.

In summary, the modified example of the second embodiment of the present invention is a case where the imaging probe 200 photographs a living tissue located in front. In this case, at least a portion of the protection window 230 may be formed of a light transmitting material, and the light guide element 230 may not exist. Therefore, the suction member 300 is only responsible for attaching to the biological tissue, and the imaging light of the biological tissue may be transmitted to the optical element 220 through the protection window 230 (see FIG. 4).

On the contrary, a modification of the second embodiment of the present invention is a case where the imaging probe 200 photographs a living tissue facing the outer surface of the exterior member 210. In this case, the cover cap 230-1 may be formed of a light opaque material. In addition, at least a portion of the suction member 300 may be formed of a light transmitting material. In addition, the light guide device 240 may further include. Therefore, while the suction member 300 is attached to the biological tissue, the imaging light of the biological tissue may pass through the suction member 300 and then be guided by the light guide element 240 to be irradiated to the optical element 220. (See FIG. 5).

Therefore, the rigidity of the first suction tube 410 inserted into the biological tissue may be greater than the rigidity of the second suction tube 420 not inserted into the biological tissue. In this case, the pump 700 may be connected to the second suction tube 420 to form a negative pressure inside the first suction tube 410 and the second suction tube 420. As a result, the first suction tube 410 may suck and fix the sample, and thus, in the third embodiment, the first suction tube 410 may have substantially the same effect as the fixing effect of the first and second embodiments.
