Description

Image acquisition method of split endoscope system in tissue cavity
Technical Field
The present disclosure generally relates to a method of image acquisition within a tissue cavity of a split-type endoscopic system.
Background
With the development of technologies such as photoelectric technology, robot technology, wireless communication technology, etc., medical instruments are beginning to be developed towards miniaturization, intellectualization, noninvasive examination, etc., for example, in the field of digestive tract examination, the use of miniature medical instruments to acquire pathological information in the gastric cavity is becoming a research hotspot gradually.
Currently, for a lesion in the stomach cavity (e.g., a polyp on the stomach wall), a doctor or the like can perform image acquisition in the stomach cavity using a capsule endoscope having an image acquisition function to acquire pathological information of the lesion region. Compared with the traditional method for acquiring images in the gastric cavity, the capsule endoscope has the advantages of simple operation, convenient examination, no wound, no pain, no cross infection, no influence on the normal work of a patient and the like.
In the conventional method for acquiring an image in a gastric cavity, a capsule endoscope having both an illumination device and an image acquisition device is generally used, and the gastric cavity can be illuminated by using the capsule endoscope having an illumination function, so that a clearer image is acquired. However, the capsule endoscope having both the illumination device and the image acquisition device consumes a large amount of electric power during examination, and the use of such a capsule endoscope limits the effective examination time in the stomach cavity. In addition, the capsule endoscope with the illuminating device and the image acquisition device has larger volume, the difficulty of leading in or out the gastric cavity is increased by using the capsule endoscope, and the operation flexibility of examination in the gastric cavity is reduced.
Disclosure of Invention
The present disclosure has been made in view of the above-mentioned state of the art, and an object thereof is to provide an image capturing method of a split-type endoscope system within a tissue cavity, which is capable of easily introducing/discharging the tissue cavity and has high operability and flexibility.
To this end, the present disclosure provides an image capturing method of a split endoscope system in a tissue cavity, the split endoscope system including an illumination capsule having an illumination function and a capture capsule having an image capturing function, the method comprising: filling the tissue cavity with a liquid; passing the illumination capsule and the collection capsule into the tissue cavity, the collection capsule having a specific gravity no greater than that of the liquid; the collecting capsule moves up and down along with the liquid level by adjusting the liquid level height of the liquid; and controlling the capture capsule to capture an image within the tissue cavity, and the illumination capsule to provide illumination light to the capture capsule.
In the image capturing method according to the present disclosure, illumination is performed in the tissue cavity by using the illumination capsule having the illumination function, and image capturing is performed in the tissue cavity by using the capturing capsule having the image capturing function. In this case, by arranging the illumination device and the image acquisition device in the two capsules, respectively, the capsule volume can be effectively reduced, so that the capsule can be conveniently introduced into/taken out of the tissue cavity, and the operability and flexibility of the capsule are improved.
Further, in the image acquisition method according to the present disclosure, optionally, the acquisition capsule has a built-in magnet, and the movement of the acquisition capsule within the tissue cavity is controlled by magnetically controlling the built-in magnet. Therefore, the collection capsule can be conveniently controlled to move in the tissue cavity through magnetic control.
In addition, in the image capturing method according to the present disclosure, optionally, the capturing capsule does not have a magnetic effect with the illuminating capsule. In this case, when the acquisition capsule is magnetically controlled, the illumination capsule is not affected by the magnetic control, and thus, the influence of the magnetic control on the illumination capsule can be avoided.
Further, in the image acquisition method according to the present disclosure, optionally, a specific gravity of the illumination capsule is not greater than a specific gravity of the liquid. Thereby, it can be facilitated that the illumination capsule floats on the surface of the liquid.
Further, in the image acquisition method according to the present disclosure, optionally, a level of the liquid is adjusted by adding an amount of the liquid into the tissue cavity. In this case, the up-and-down movement of the collecting capsule can be conveniently controlled by adjusting the liquid level of the liquid.
In addition, in the image capturing method according to the present disclosure, optionally, the illumination capsule has illumination devices provided at both ends. Therefore, the illumination range of the illumination capsule in the tissue cavity can be effectively increased.
In addition, in the image capturing method according to the present disclosure, optionally, the capturing capsule has an activation switch for entering an image capturing mode, and the capturing capsule captures an image in the tissue cavity by turning on the activation switch. Therefore, the acquisition capsule can be conveniently activated to acquire images in the tissue cavity.
In addition, in the image capturing method according to the present disclosure, optionally, when the capturing capsule captures an image, the capturing capsule floats on a liquid surface of the liquid. In this case, the capture capsule floats on the liquid surface of the liquid, whereby it is possible to facilitate image capture of a portion above the liquid surface of the liquid.
Further, in the image capturing method according to the present disclosure, optionally, a center of gravity of the capturing capsule is offset from a center of the capturing capsule. This can increase the stability of the collection capsule when floating on the liquid surface of the liquid.
Further, in the image capturing method according to the present disclosure, optionally, the illumination capsule has a battery for supplying power to the illumination device, and a volume of the battery occupies more than 40% of a volume of the illumination capsule. Thereby, power supply to the lighting device can be facilitated.
According to the present disclosure, it is possible to provide an image capturing method of a split type endoscope system within a tissue cavity, which can conveniently introduce/discharge the tissue cavity and has high operational flexibility.

Embodiments of the present disclosure relate to a method of image acquisition within a tissue cavity of a split-type endoscopic system. The split endoscope system may be simply referred to as an endoscope system, and the endoscope system may collect images within a tissue cavity of a subject, thereby performing medical examination on the tissue cavity of the subject. Hereinafter, an image capturing method according to the present embodiment will be described in detail with reference to the drawings.
Fig. 1 is an application diagram illustrating an image acquisition method according to an example of the present disclosure. Fig. 2 is a flow chart diagram illustrating an image acquisition method according to an example of the present disclosure.
In the present embodiment, the endoscope system 2 can be used to acquire an image of the tissue cavity 11 of the subject 1. In some examples, the endoscope system 2 may include an illumination capsule 21 having an illumination function and a capture capsule 22 having an image capture function. In addition, in some examples, the endoscope system 2 may further include a magnetron device 23 having a magnetron function and a display device 24 having an image display function (see fig. 1).
Specifically, in the present embodiment, as shown in fig. 2, the image acquisition in the tissue cavity 11 may include the following steps: first, a tissue cavity 11 is filled with a liquid 12 (step S100). Next, illumination capsule 21 and collection capsule 22 are introduced into tissue cavity 11 filled with liquid 12 (step S200). Then, illumination is performed within the tissue cavity 11 using the illumination capsule 21, and image acquisition is performed within the tissue cavity 11 using the acquisition capsule 22 (step S300). Finally, the height of the liquid level of the liquid 12 is adjusted to move the collection capsule 22 up and down along with the liquid level, so as to collect images of different parts of the tissue cavity 11 (step S400).
In the present embodiment, illumination is performed in the tissue cavity 11 by using an illumination capsule 21 having an illumination function, and image acquisition is performed in the tissue cavity 11 by using an acquisition capsule 22 having an image acquisition function. In this case, by arranging the illumination device 211 and the image acquisition device 221 in two capsules, respectively, the volume of the capsules can be effectively reduced, so that the capsules can be conveniently introduced into/out of the tissue cavity 11. In addition, the tissue cavity 11 is filled with a liquid 12 and the specific gravity of the collection capsule 22 is not greater than the specific gravity of the liquid 12. In this case, the collection capsule 22 can float on the surface of the liquid 12, and the collection capsule 22 is moved up and down by adjusting the height of the liquid 12, whereby the operational flexibility of the collection capsule 22 in the tissue cavity 11 can be effectively improved.
In some examples, the tissue cavity 11 may be a digestive lumen such as a stomach lumen, a large intestine lumen, a small intestine lumen, or the like, and the subject 1 may introduce the illumination capsule 21 and the acquisition capsule 22 into the digestive lumen by, for example, swallowing or the like. Hereinafter, the image capturing method according to the present embodiment will be described in detail with reference to the drawings, taking the gastric cavity as an example.
Fig. 3 is a schematic diagram illustrating a stomach cavity filled with liquid 12 in accordance with an example of the present disclosure.
In the present embodiment, as described above, in step S100, the liquid 12 may be filled in the stomach cavity first. When the stomach cavity is filled with the liquid 12, the folds of the inner wall of the stomach cavity can be effectively reduced, thereby more effectively performing image acquisition in the stomach cavity (see fig. 3).
In some examples, the liquid 12 may be a liquid 12 that is relatively light transmissive. In some examples, the liquid 12 may be saline.
In some examples, the subject 1 may fill the stomach cavity with the liquid 12 by swallowing the liquid 12. In some examples, the subject 1 may fill the stomach cavity with the liquid 12 in a lying state. In other examples, the subject 1 may fill the stomach cavity with the liquid 12 in a standing state.
In some examples, the liquid 12 may occupy 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% of the volume of the gastric cavity before the illumination capsule 21 and the acquisition capsule 22 are introduced into the gastric cavity, i.e. before step S200 is performed.
In the present embodiment, as described above, in step S200, when the stomach cavity is filled with the liquid 12, the illumination capsule 21 and the acquisition capsule 22 may be introduced into the stomach cavity, thereby performing illumination and image acquisition within the stomach cavity.
In some examples, the subject 1 may introduce the illumination capsule 21 and the acquisition capsule 22 into the stomach cavity by swallowing. In some examples, the subject 1 may swallow the illumination capsule 21 first and then swallow the capture capsule 22. In other examples, the subject 1 may swallow the capture capsule 22 first and then swallow the illumination capsule 21.
In some examples, the illumination capsule 21 may be in an activated state, i.e., a state in which illumination light has been emitted, before the subject 1 swallows the illumination capsule 21. In some examples, the illumination capsule 21 may emit white light to illuminate within the stomach cavity.
Fig. 4A is a schematic diagram showing the structure of the illumination capsule 21.
In some examples, the illumination capsule 21 may have illumination devices 211 disposed at both ends (see fig. 4A). This can effectively improve the illumination effect of the illumination capsule 21 in the stomach cavity. In other examples, illumination capsule 21 may have illumination device 211 disposed at one end. This can effectively reduce power consumption of the illumination capsule 21 when it is illuminated. In some examples, the illumination capsule 21 may have a centrally disposed illumination device 211.
In some examples, the illumination capsule 21 may have a battery 212 to power the illumination device 211, and the volume of the battery 212 may occupy more than 40% of the volume of the illumination capsule 21 (see fig. 4A). In some examples, the volume of battery 212 may occupy 40%, 45%, 50%, 55%, 60%, 65%, or 70% of the volume of illumination capsule 21. This enables the lighting device 211 to be efficiently supplied with power.
In some examples, illumination capsule 21 may be a medical device shaped as a capsule. In some examples, the illumination capsule 21 may be shaped as a sphere. In some examples, the illumination capsule 21 may be shaped like an ellipsoid.
In some examples, the diameter of the illumination capsule 21 may be no greater than 10 mm. In some examples, the diameter of the illumination capsule 21 may be 10mm, 9mm, 8mm, 7mm, 6mm, or 5 mm. In some examples, the length of the illumination capsule 21 may be no greater than 25 mm. In some examples, the length of the illumination capsule 21 may be 25mm, 24mm, 23mm, 22mm, 21mm, 20mm, 19mm, 18mm, 17mm, 16mm, 15mm, 14mm, 13mm, 12mm, 11mm, 10mm, 9mm, 8mm, 7mm, 6mm, or 5 mm.
In some examples, the specific gravity of the illumination capsule 21 may not be greater than the specific gravity of the liquid 12. In some examples, the illumination isThe average density of the capsules 21 may be no greater than 0.9g/cm3. In some examples, the average density of the illumination capsule 21 may be 0.9g/cm3、0.85g/cm3、0.8g/cm3、0.75g/cm3、0.7g/cm3、0.65g/cm3、0.6g/cm3、0.55g/cm3、0.5g/cm3Or 0.4g/cm3. Thus, the illumination capsule 21 can float above the surface of the liquid 12, thereby facilitating illumination above the surface of the liquid 12.
In other examples, the specific gravity of the illumination capsule 21 may be greater than the specific gravity of the liquid 12. In some examples, the average density of the illumination capsules 21 may be greater than 0.9g/cm3. In some examples, the average density of the illumination capsule 21 may be 0.95g/cm3、1.0g/cm3、1.05g/cm3、1.1g/cm3、1.15g/cm3、1.2g/cm3、1.25g/cm3、1.3g/cm3、1.35g/cm3、1.4g/cm3、1.45g/cm3Or 1.5g/cm3. Thus, the illumination capsule 21 can be submerged below the liquid surface of the liquid 12, thereby facilitating illumination below the liquid surface of the liquid 12.
Fig. 4B is a schematic diagram showing the structure of the acquisition capsule 22.
In some examples, the acquisition capsule 22 may have an image acquisition device 221 and a built-in magnet 222 (see fig. 4B). The image capturing device 221 can capture an image, and the built-in magnet 222 can be acted on by a magnetic force.
In some examples, the magnetron device 23 may magnetically control the built-in magnet 222 of the acquisition capsule 22 to control movement of the acquisition capsule 22 within the gastric cavity. Thereby, the movement of the acquisition capsule 22 can be conveniently controlled by magnetic control.
In some examples, the collection capsule 22 may also have a delivery device 223 (see fig. 4B). Thus, images acquired by the acquisition capsule 22 within the gastric cavity can be conveniently transmitted to the display device 24. In some examples, the transmission device 223 may be a wireless transmission device such as a bluetooth transmission device, a WIFI transmission device, an NFC transmission device, or the like. In other examples, the transmitting device 223 may be a wired transmitting device such as a USB transmitting device, an HDMI transmitting device, a VGA transmitting device, and the like.
In some examples, the acquisition capsule 22 may be a capsule-shaped housing. In some examples, the capsule-type housing may be composed of a cylindrical main housing and two hemispherical end housings at both ends of the main housing, which in combination may be formed as an airtight packaging structure, i.e., the capsule-type housing, to maintain a liquid-tight state inside the collecting capsule 22.
In some examples, the end housings may be transparent optical elements capable of transmitting light of a specified wavelength (e.g., visible light), wherein both end housings may be transparent optical elements or only one of them may be transparent optical elements. In some examples, the image capture device 221 may be disposed at one end with a transparent optical element. Thus, light within the gastric cavity can pass through the transparent optical element to reach the image capture device 221, thereby facilitating image capture.
In some examples, the acquisition capsule 22 may have a power supply 224 (see fig. 4B). Thereby, the collection capsule 22 can be conveniently powered.
In some examples, there may be no magnetic interaction between the acquisition capsule 22 and the illumination capsule 21. In this case, there is no influence of magnetic control between the capturing capsule 22 and the illuminating capsule 21, that is, when the capturing capsule 22 is magnetically controlled using the magnetron device 23, the illuminating capsule 21 may be moved without being influenced by the magnetic control. Therefore, the operation flexibility of the acquisition capsule 22 can be effectively improved, and the misoperation of the illumination capsule 21 caused by magnetic control can be effectively avoided.
In some examples, the acquisition capsule 22 may have an activation switch (not shown) that enters an image acquisition mode, by which activation switch the acquisition capsule 22 may be caused to acquire images within the gastric cavity. Thereby, the acquisition capsule 22 can be conveniently activated for image acquisition.
In some examples, the center of gravity of the acquisition capsule 22 may be offset from the center of the acquisition capsule 22. In some examples, the center of gravity of the acquisition capsule 22 may be disposed on the centerline of the acquisition capsule 22. This effectively increases the stability of the collection capsule 22 when it floats on the surface of the liquid 12. In some examples, the center of gravity of the acquisition capsule 22 may be disposed at an end remote from the image acquisition device 221, thereby enabling to facilitate image acquisition above the level of the liquid 12. In other examples, the center of gravity of the acquisition capsule 22 may be disposed near an end of the image acquisition device 221, thereby facilitating image acquisition below the level of the liquid 12.
In some examples, the diameter of the acquisition capsule 22 may be no greater than 10 mm. In some examples, the diameter of the acquisition capsule 22 may be 10mm, 9mm, 8mm, 7mm, 6mm, or 5 mm. In some examples, the length of the acquisition capsule 22 may be no greater than 25 mm. In some examples, the length of the collection capsule 22 may be 25mm, 24mm, 23mm, 22mm, 21mm, 20mm, 19mm, 18mm, 17mm, 16mm, 15mm, 14mm, 13mm, 12mm, 11mm, 10 mm.
In some examples, the specific gravity of the collection capsule 22 may not be greater than the specific gravity of the liquid 12. In some examples, the average density of the acquisition capsule 22 may be no greater than 0.9g/cm3. In some examples, the average density of the acquisition capsule 22 may be 0.9g/cm3、0.85g/cm3、0.8g/cm3、0.75g/cm3、0.7g/cm3、0.65g/cm3、0.6g/cm3、0.55g/cm3、0.5g/cm3Or 0.4g/cm3. Thus, the capture capsule 22 is able to float above the surface of the liquid 12, thereby facilitating image capture above the surface of the liquid 12.
In other examples, the specific gravity of the collection capsule 22 may be greater than the specific gravity of the liquid 12. In some examples, the average density of the acquisition capsule 22 may be greater than 0.9g/cm3. In some examples, the average density of the acquisition capsule 22 may be 0.95g/cm3、1.0g/cm3、1.05g/cm3、1.1g/cm3、1.15g/cm3、1.2g/cm3、1.25g/cm3、1.3g/cm3、1.35g/cm3、1.4g/cm3、1.45g/cm3Or 1.5g/cm3. Thereby, the collecting glueBladder 22 is capable of submerging below the surface of liquid 12 to facilitate image acquisition below the surface of liquid 12.
In some examples, the surface of collection capsule 22 may have a hydrophobic layer. In some examples, the hydrophobic contact angle of the hydrophobic layer may be greater than 90 degrees. Therefore, the phenomenon that imaging is unclear due to the fact that water drops are attached to the surface can be effectively avoided.
Fig. 5 is a schematic diagram illustrating image acquisition in accordance with an example of the present disclosure.
In the present embodiment, as described above, in step S300, after the illumination capsule 21 and the acquisition capsule 22 enter the stomach cavity filled with the liquid 12, the illumination capsule 21 may be used to illuminate the stomach cavity and the acquisition capsule 22 may be used to acquire an image of the stomach cavity.
In some examples, the acquisition capsule 22 may float above the surface of the liquid 12 (see fig. 5) when the acquisition capsule 22 is performing image acquisition. This facilitates image capture of a portion of the liquid 12 above the liquid surface. In other examples, the acquisition capsule 22 may be submerged below the level of the liquid 12 when the acquisition capsule 22 is performing image acquisition. This facilitates image capture of the portion of the liquid 12 below the liquid surface.
In some examples, the illumination capsule 21 may float above the surface of the liquid 12 when the acquisition capsule 22 performs image acquisition, thereby conveniently illuminating a site above the surface. In some examples, the illumination capsule 21 may be submerged below the surface of the liquid 12 when the capture capsule 22 is performing image capture, thereby conveniently illuminating the sub-surface region. In some examples, the illumination capsule 21 may be proximate to the inner wall of the stomach cavity when the acquisition capsule 22 is performing image acquisition, thereby enabling illumination of the inner wall of the stomach cavity. In some examples, the illumination capsule 21 may be centered on the level of the liquid 12 when the acquisition capsule 22 is performing image acquisition, thereby enabling illumination of the entire stomach cavity.
In some examples, the magnetic control device 23 may move the acquisition capsule 22 over the surface of the liquid 12 by magnetically controlling the built-in magnet 222 when the acquisition capsule 22 performs image acquisition. For example, in some examples, the acquisition capsule 22 may be moved annularly above the level of the liquid 12 and adjacent to the inner wall of the stomach cavity (see fig. 5), thereby facilitating image acquisition of the inner wall of the stomach cavity. In some examples, the magnetic control device 23 may also be magnetically controlled to adjust the attitude angle of the acquisition capsule 22 (see fig. 5) when the acquisition capsule 22 performs image acquisition.
In some examples, the level of the liquid 12 may be adjusted by increasing the amount of liquid 12 into the stomach cavity when the acquisition capsule 22 performs image acquisition. For example, in some examples, by increasing the amount of liquid 12 into the stomach cavity, the acquisition capsule 22 may rise with the level of liquid 12, thereby enabling image acquisition of the stomach cavity from bottom to top within the stomach cavity.
In other examples, the level of liquid 12 may be adjusted by reducing the amount of liquid 12 within the gastric cavity when acquisition capsule 22 performs image acquisition. For example, in some examples, by reducing the amount of liquid 12 within the gastric cavity, acquisition capsule 22 may descend with the level of liquid 12, thereby enabling image acquisition of the gastric cavity from top to bottom within the gastric cavity.
Hereinafter, the image capturing method according to the present embodiment will be described in detail with reference to fig. 3.
First, in step S100, the subject 1 swallows the stomach under the guidance of a doctor to fill the stomach cavity with the liquid 12. Next, in step S200, when the amount of the liquid 12 in step S100 reaches 10% of the volume of the stomach cavity, the subject 1 introduces the illumination capsule 21 and the capture capsule 22 into the stomach cavity in order by swallowing under the direction of the doctor, and the illumination capsule 21 is already in an activated state before the introduction of the illumination capsule 21. Then, in step S300, the image capturing device 2 of the capturing capsule 22 is activated, and the capturing capsule 22 is controlled by the magnetic control device 23 to perform a circular movement on the liquid surface of the liquid 12 and along the inner wall of the stomach cavity, perform image capturing on the inner wall of the stomach cavity while moving, and transmit the captured image to the display device 24 for displaying. Finally, in step S400, the amount of the liquid 12 in the stomach cavity is slowly increased to slowly raise the liquid level of the liquid 12, while continuing to perform the operation in step S300, so that the acquisition capsule 22 performs image acquisition from bottom to top in a spiral manner along the inner wall of the stomach cavity in the stomach cavity.
The present embodiment is not limited thereto, and the execution sequence of the above steps may be appropriately adjusted, for example, in some cases, the subject 1 may first introduce the illumination capsule 21 and the collection capsule 22 into the stomach cavity, and then fill the stomach cavity with the liquid 12.
According to the present disclosure, it is possible to provide an image capturing method of a split type endoscope system within a tissue cavity, which can conveniently introduce/discharge the tissue cavity and has high operational flexibility.
While the present disclosure has been described in detail above with reference to the drawings and the embodiments, it should be understood that the above description does not limit the present disclosure in any way. Those skilled in the art can make modifications and variations to the present disclosure as needed without departing from the true spirit and scope of the disclosure, which fall within the scope of the disclosure.
