Description

TECHNICAL FIELD

[0001] The present application relates to the field of image acquisition, and in particular to a system with image capturing function. BACKGROUND

[0002] In the medical field, there are various treatment methods, some of which can be completed by body surface operation, and some of which need to be invasive to the patient's body. There are natural cavities in the human body, such as the nasal cavity, oral cavity, urethra, etc., and artificial fistulas can also be formed to facilitate the entry of instruments.

[0003] Currently, if a medical instrument is to be sent into the body and to a predetermined position, a treatment or observation channel is generally constructed in advance, and then the medical instrument is sent in through this relatively fixed channel. However, the problem is that there is a certain risk in the construction of this treatment or observation channel. For example, there are a large number of blood vessels in the human body, and if the operator directly forms this treatment or observation channel by puncture, it may lead to excessive or insufficient penetration, and if it is penetrated too deeply, it may directly insert into the blood vessel and cause massive bleeding. In order to reduce this risk, one way is to establish this treatment or observation channel under visual conditions.

[0004] Reference is made to the accompanying drawings Figure 1A and the accompanying drawings Figure 1B , which respectively show two kinds of pipe fittings for establishing a channel at present. The pipe fitting 1P in the accompanying drawings Figure 1A has a first channel 110P and a second channel 120P, and a first opening 101P and a second opening 102P corresponding to the first channel 110P and the second channel 120P respectively, the first opening 101P is communicated with the first channel 110P, the second opening 102P is communicated with the second channel 120P, and the first opening 101P and the second opening 102P are arranged flush. The first channel 110P is adapted to be installed with an image capturing element, and the second channel 120P is adapted to pass through a guide wire, the pipe fitting 1P enters along the guide wire and adjusts the direction and speed of entry in time according to the image captured by the image capturing element. The pipe fitting 2P in the accompanying drawings Figure 1BThe pipe 1P' is similarly provided with the first channel 110P', the second channel 120P', the first opening 101P' and the second opening 102P', with the main difference being that the first opening 101P' for mounting the image capturing device is arranged protruding relative to the second opening 102P'. In actual use, the operator finds that the capturing effect of the image capturing device arranged on the pipe 1P, 1P' is not good, and it is difficult to timely feedback to guide the operator to adjust the entering direction and speed, which may cause deviation of puncture.

[0044] Summary of the application

[0045] As shown in the background, the existing pipe for establishing a channel is limited to the structure of the pipe itself, the arrangement of the first opening and the second opening, and the size requirement itself in actual use, and cannot capture the desired image information, so that the whole process still faces the risk of improper puncture, which is easy to puncture too deep to cause massive bleeding, or puncture too shallow to reach the expected position.

[0046] In the process of continuously pushing the tube towards the patient's body, the image capturing element is continuously capturing images in front, and the image capturing element itself is arranged at the front end of the tube. Since it cannot capture itself, once the speed is too fast, the image capturing element has a high probability of sticking forward to an unexpected position, causing damage. In other words, the existing tube for establishing a channel has a visual blind area, causing the operator to be unable to take the correct operation in time.

[0047] The technical concept of the present application is to creatively design the related equipment under full consideration of the actual application scene of establishing a channel in the body, so that the doctor can not only clearly observe the status in front during the operation, but also can operate under the visible condition, which helps the doctor to quickly and efficiently complete the entire channel establishment process.

[0048] Based on this, the present application provides a system with image capturing function, which includes an image capturing unit, a processing unit and a mounting unit, wherein the system is suitable for mounting a guide element and a dilation unit, the image capturing unit is used for capturing image information, the processing unit is communicatively connected to the image capturing unit to process the image information obtained by the image capturing unit, wherein the mounting unit is suitable for being detachably mounted in the operation channel of the dilation unit, the mounting unit has a working channel and a mounting channel, and a working port and a mounting port are respectively communicated with the working channel and the mounting channel, wherein when the mounting unit is mounted in the dilation unit, the working port and the mounting port are located outside the operation channel of the dilation unit, the image capturing unit is arranged in the working channel of the mounting unit, the guide element is mounted in the mounting channel of the mounting unit, and the image capturing unit is configured to capture the image information of the guide element extending out of the mounting port at and around the mounting port position.

[0049] Exemplary embodiments

[0050] With reference to the drawings of the present application Figures 2 to 6 , an embodiment of the present application provides a system with image capturing function, which can assist medical personnel to establish a surgical channel or an observation channel in the human body or the body of animals and plants. For example, in the percutaneous nephrolithotomy surgery of kidney stones, a surgical channel can be established by using the system with image capturing function, and then the corresponding lithotripsy instrument is placed into the expected position through the surgical channel.

[0051] In detail, the system with image capturing function comprises an image capturing unit 10, a processing unit 20 and a mounting unit 30, the image capturing unit 10 is adapted to be mounted on the mounting unit 30, and the processing unit 20 is communicatively connected to the image capturing unit 10 to process the image information captured by the image capturing unit 10.

[0052] The system with image capturing function can further comprise a guide 40 and an expansion unit 50, wherein the expansion unit 50 has an operation channel 500, the mounting unit 30 is adapted to be mounted on the expansion unit 50 and to pass through the operation channel 500, and the guide 40 is adapted to be mounted on the mounting unit 30 to guide the mounting unit 30 into the body.

[0053] With reference to the accompanying drawings, the specific embodiments of the present application will be described in detail. Figure 3 The application process of the system with image capturing function is shown in the figure. First, the expansion unit 50, the guide 40 and the image capturing unit 10 are mounted on the mounting unit 30 respectively, wherein the guide 40 passes through the mounting unit 30, the image capturing unit 10 is limitedly mounted on the mounting unit 30, the mounting unit 30 passes through the expansion unit 50 and extends out of the expansion unit 50. In actual operation, the mounting unit 30 is guided by the guide 40 and gradually sent into the body by the operator with the assistance of the image capturing unit 10, and at the same time, the expansion unit 50 wrapped outside the mounting unit 30 is also sent into the body. Then, based on the image information captured by the image capturing unit 10, the operator or the operating device determines that the mounting unit 30 has been sent to the desired position, and then the mounting unit 30 with the image capturing unit 10 can be detached from the expansion unit 50 to restore the operation channel 500 of the expansion unit 50 to the idle state. Finally, an operation unit 70, which can be a corresponding surgical instrument or a drug delivery device, is sent into the target position through the operation channel 500 provided by the remaining expansion unit 50 to complete the whole process.

[0054] In the above process, the mounting unit 30 can assist the image capturing unit 10 to capture ideal image information to assist the operator to operate quickly and safely.

[0055] Specifically, with reference to the accompanying drawings, Figure 4 to the accompanying drawings, Figure 6The installation unit 30 has a working channel 310, an installation channel 320, and a working port 301 and an installation port 302 respectively connected to the working channel 310 and the installation channel 320, and the working port 301 and the installation port 302 are located at the end of the installation unit 30. When the installation unit 30 is installed in the expansion unit 50, the working port 301 and the installation port 302 of the installation unit 30 are exposed outside the expansion unit 50 to collect as much surrounding environment information as possible in front of the movement of the installation unit 30 and the expansion unit 50.

[0056] The image capture unit 10 is configured to capture image information of the guide 40 extending from the installation port 302 at the position of the installation port 302 and around. In the existing pipe, the image capture unit 10 is difficult to capture image information at the position of the installation port 302, which brings the following problems, the position of the installation port 302 is in a blind area, once the guide 40 is curled or blocked by stones and the like at the position of the installation port 302, the operator is difficult to find in time, which prolongs the pipe time and increases the probability of accidents. In addition, the installation port 302 is in a blind area, which makes it impossible for the operator to observe the environment information at the front end of the installation unit 30, which is still in a blind state.

[0057] By capturing the position information of the installation port 302 by the image capture unit 10, the above problems can be solved, and the visual operation is truly realized, which is beneficial to the operator to complete the entire operation in a short time under the premise of safety.

[0058] More specifically, the working port 301 is arranged on the rear side of the installation port 302, and the relative positions of the working port 301 and the installation port 302 are designed to enable the image capture unit 10 installed in the working port 301 to capture image information at the position of the installation port 302.

[0059] The image capture unit 10 can be an electronic camera device or an image transmission optical fiber device, which is taken as an example here.

[0060] A camera of the image capture unit 10 can be arranged at the position of the working port 301 and capture image information forwardly. It can be understood that here the direction of the working port 301 and the installation port 302 of the installation unit 30 is forward, and the other end of the installation unit 30 without the working port 301 and the installation port 302 is backward.

[0061] The installation port 302 is arranged within a working range of the camera of the image capturing unit 10, so that the image of the guide 40 passing through the installation port 302 is captured.

[0062] It is worth mentioning that the installation port 302 is arranged at the most front end of the installation unit 30, and the installation port 302 and the information around the installation port 302 can be captured by the image capturing unit 10, so that the image capturing unit 10 can truly capture the information of the most front end of the installation unit 30, to provide accurate information for the operator or the related operation system, thereby avoiding the case that the most front end of the installation unit 30 penetrates too deep and the operator or the related operation system fails to timely adjust the operation.

[0063] The installation port 302 is arranged to extend forward from the position of the working port 301. The installation port 302 and the working port 301 are arranged as compact as possible to reduce the cross-sectional size of the part of the installation unit 30 that is firstly inserted into the body. In the embodiment, the installation unit 30 forms an entire opening 300, and the installation port 302 and the working port 301 are formed at the position of the opening 300, respectively. The shape of the opening 300 can be circular, oval or other shapes, which can be selected by those skilled in the art according to the needs. Preferably, the contour of the opening 300 is an arc structure to facilitate the smooth insertion of the installation unit 30 into the body.

[0064] It is worth mentioning that in the embodiment, the installation unit 30 forms the installation channel 320 and the working channel 310, and the installation channel 320 and the working channel 310 are arranged to be “separated first and combined later”. In detail, the installation unit 30 includes a surrounding wall 31 and a separation wall 32, and the separation wall 32 separates the space surrounded by the surrounding wall 31 into the installation channel 320 and the working channel 310, respectively. It can be understood that the separation wall 32 can be fully closed, can be hollow, can be arranged at intervals, or can be arranged continuously. That is, at each position of the separation wall 32, the working channel 310 and the installation channel 320 can be continuously not connected to each other, or can be arranged at intervals and connected.

[0065] The periphery of the surrounding wall 31 and the periphery of the partition wall 32 define the shape of the installation port 302 and the working port 301 respectively, and the shape of the installation port 302 and the working port 301 can be defined respectively without interfering with each other. The same part of the partition wall 32 defines the installation port 302 and the working port 301 at the same time. The periphery of the partition wall 32 forming the installation port 302 or the working port 301 is arranged to be inwardly recessed to form a gap 303, wherein the gap 303 communicates the working channel 310 and the installation channel 320, thereby forming a "separation first and then combination" structure, that is, the working channel 310 and the installation channel 320 are first separated by the partition wall 32, and then mutually penetrated due to the gap 303 formed by the partition wall 32. Through the gap 303, the image capture unit 10 is allowed to capture image information of the guide 40 in advance. According to an embodiment of the present application, the working channel 310 and the installation channel 320 can be in a separated state all the time. That is, the gap 303 can not be arranged.

[0066] Further, the guide 40 extending from the installation port 302 is arranged to extend obliquely towards the working channel 310, so that the image capture unit 10 can timely capture the guide 40. In the existing pipe, the direction of the image capture unit and the direction of the guide wire are arranged in parallel with each other. The oblique arrangement of the guide 40 extending from the installation port 302 can make at least part of the image of the guide 40 located at the optical axis position of the image capture unit 10, so as to facilitate the display of the image at a later stage. The inclined guide 40 can be located at a meridian image plane of the camera of the image capture unit 10. It can be understood that the guide 40 can be arranged below or above in the up-down direction of the image capture unit 10, or left or right in the left-right direction of the image capture unit 10.

[0067] The guide 40 extending from the installation port 302 is arranged obliquely, which is conducive to the compact arrangement of a head end 36 of the installation unit 30, so as to facilitate the installation of the installation unit 30. According to the conventional design, if the guide 40 is desired to be inclined out of the installation port 302, at least part of the installation channel 320 can also need to be designed obliquely relative to the working channel 310, thereby expanding the cross-sectional area of the installation unit 30. In the present embodiment, most of the working channel 310 and the installation channel 320 can still be arranged in parallel, and even can be arranged in parallel at the position of the head end 36, that is, the effect of the guide 40 being inclined out does not need to rely on expanding the cross-sectional area of the installation unit 30.

[0068] In detail, the surrounding wall 31 and the partition wall 32 of the mounting unit 30 define the mounting port 302 and the working port 301 at the positions of the mounting port 302 and the working port 301, and the surrounding wall 31 and the partition wall 32 can also jointly or individually play a guiding role for the guide 40. The head end 36 of the mounting unit 30 is designed as a structure with a gradually reduced cross section, and the closer to the positions of the working port 301 and the mounting port 302, the smaller the cross section. The surrounding wall 31 of the head end 36 defining the working channel 310 is arranged to be inclined, and is inclined towards the working channel 310 while extending forward to guide the guide 40 to extend forward and be inclined towards the working channel 310. In addition, under the cooperation of the gap 303 of the partition wall 32, the inclined guide 40 is not limited by the partition wall 32 at the position of the gap 303, so as to be inclined towards the working channel 310. The size of the gap 303 and the inclination of the surrounding wall 31 at the head end 36 can be set according to requirements to obtain the guide 40 with a desired inclination.

[0069] It can be understood that the inclination of the guide 40 can be realized depending on the arrangement of the surrounding wall 31 and the partition wall 32, or can be realized depending on the arrangement of the mounting port 302, which can be arranged to be inclined towards the direction in which the working channel 310 is located to constrain the guide 40 extending from the mounting port 302 to be arranged to be inclined towards the direction in which the working channel 310 is located.

[0070] In the embodiment, the mounting unit 30 has an end face 33, and the end face 33 is formed with the opening 300. The end face 33 includes a working end face 331 defining at least part of the position of the working port 301 and a mounting end face 332 defining at least part of the position of the mounting port 302. The working end face 331 is arranged to be an inclined arc shape, and the side of the working end face 331 away from the mounting end face 332 extends forward and inward to the mounting end face 332. The mounting end face 332 can be arranged as an arc shape close to a plane, and can be in a state of relative perpendicularity with a central axis of the image capture unit 10. In other words, the position of the working port 301 forms a larger inclination and is relatively sharp, and the position of the mounting port 302 forms a smaller inclination and is relatively flat. Those skilled in the art can adjust the arrangement of the end face 33 of the mounting unit 30 according to requirements.

[0071] Furthermore, regarding the installation opening 302, the surrounding wall 31 forming the installation opening 302 protrudes from the partition wall 32 forming the installation opening 302, thereby forming a structure similar to a hat brim. This "hat brim" structure can protect the guide member 40 and reduce the impact of the body tissue squeezing the guide member 40 during the forward advancement of the installation unit 30.

[0072] With respect to the working port 301, the surrounding wall 31 forming the working port 301 can be arranged in a similar position to the partition wall 32 forming the working port 301, thereby reducing obstruction to the image capture unit 10. It is understood that when the image capture unit 10 is installed in the working channel 310, the working port 301 restricts the image capture unit 10 so that the camera of the image capture unit 10 is in a relatively stable position.

[0073] The shapes of the mounting opening 302 and the working opening 301 can be configured separately and can be circular, elliptical, or other structures. In this embodiment, the opening 300 of the mounting unit 30 is configured to be flat, and accordingly, the head end 36 of the mounting unit 30 is flat to facilitate installation of the mounting unit 30. The mounting opening 302 and the working opening 301 can each be circular, and the mounting opening 302 and the working opening 301 can overlap to form a flat shape.

[0074] Furthermore, the system with image capture function may further include a display unit 60, wherein the display unit 60 is communicatively connected to the processing unit 20 to display image information. The display unit 60 may be a physical display or a virtual display screen, for example, projected by a projection device. The image captured by the image capture unit 10 is displayed on the display unit 60. Figure 7A and 7B As shown, different display effects according to two embodiments of the present invention are illustrated.

[0075] In the attached Figure 7A In the illustrated embodiment, the image capture unit 10 is positioned above the guide member 40. During installation of the mounting unit 30, the image capture unit 10 remains above the guide member 40. On the display unit 60, at least a portion of the guide member 40 is positioned at the visual center of the display unit 60, and the guide member 40 extends upward from below. The mounting opening 302 is located slightly below the entire display unit 60.

[0076] In the attached Figure 7BIn the illustrated embodiment, the image capturing unit 10 is arranged below the guide 40, and during the installation of the installation unit 30, the image capturing unit 10 is always above the guide 40. On the display unit 60, at least part of the guide 40 is displayed in the visual center of the display unit 60, and the guide 40 extends downward from above. The installation port 302 is located in the upper position in the entire area of the display unit 60.

[0077] It can be understood that, based on the structural design of the installation unit 30, the relative positions of the guide 40 and the image capturing unit 10 are controlled, so that the part of the guide 40 located on the meridian plane of the image capturing unit 10 can be displayed in the visual center of the display unit 60, so that the visual perception and control operation of the operator are consistent, that is, the operator can directly adjust the orientation and speed of the installation unit 30 based on the display result of the display unit 60, and the actual position of the installation unit 30 can also be adjusted accordingly. In other words, the actual adjustment and the visual result are consistent, and there is no visual deviation that requires the operator to think before adjusting.
