Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an insertion part, an endoscope, an intrarenal pressure detection system and an endoscope processing system. BACKGROUND

[0002] In the field of minimally invasive treatment of urology, transurethral ureteroscopy laser lithotripsy has become an important treatment for upper urinary tract calculi due to its significant advantages of small trauma and rapid recovery. However, the accurate control of intrarenal pressure during the operation is always a core challenge affecting the safety of the operation. The continuous perfusion of the renal pelvis and the accumulation of debris generated by stone crushing during the operation can lead to abnormally high intrarenal pressure, and the high intrarenal pressure can cause acute complications such as renal parenchyma injury and renal pelvis venous reflux, and significantly increase the risk of postoperative infection and sepsis. Therefore, real-time monitoring and accurate regulation of intrarenal pressure are key technical requirements for optimizing the safety of the operation and the clinical prognosis.

[0003] At present, the monitoring of intrarenal pressure during the operation mainly relies on two types of schemes, namely, endoscope integrated pressure sensing technology and indirect measurement in vitro. The former realizes real-time feedback by embedding a miniature pressure sensor at the front end of the ureteroscope insertion part, but is limited by the size and power supply requirements of the sensor. Such design significantly increases the diameter of the end of the endoscope, resulting in decreased operational flexibility when the scope passes through the narrow ureter, and even increases the risk of intraoperative tissue damage. The latter connects a pressure sensor in vitro through an extended pipeline, but due to the long perfusion pipeline, dynamic changes in the flow resistance of the irrigation fluid, and fluctuations in the manual perfusion pressure, there is a significant error between the actual measured pressure value and the true intrarenal pressure, especially during complex surgical fields or stone crushing operations, making it difficult to achieve accurate calibration.

[0004] Therefore, it is a technical problem to be solved by those skilled in the art to develop a miniaturized, low-delay, high-precision intrarenal pressure detection technology. SUMMARY

[0005] The present application discloses an insertion part, an endoscope, an intrarenal pressure detection system and an endoscope processing system to solve the above technical problems in the related art.

[0006] To solve the above problems, the present application adopts the following technical solutions:

[0007] In a first aspect, the present application provides an insertion part applied to an endoscope, the insertion part comprising an insertion part body and a transparent display screen, the transparent display screen being movably arranged at the distal end of the insertion part body; wherein:

[0008] The transparent display screen is used for displaying a mark, a camera module and a window opening corresponding to the camera module are arranged in the insertion part body, the transparent display screen is distributed on the far end side of the camera module, and at least part of the transparent display screen is located in the optical area of the window opening, and the mark can be captured by the camera module.

[0009] In a second aspect, the present application provides an endoscope, which comprises the insertion part as described above.

[0010] In a third aspect, the present application further provides a renal pressure detection system based on the insertion part as described above, which comprises:

[0011] A first acquisition module is configured to acquire first image information collected by the camera module, wherein the first image information comprises environmental image information and mark image information;

[0012] A recognition module is configured to recognize the mark image information in the first image information;

[0013] A comparison module is configured to compare the mark image information with standard image information, wherein the standard image information is image information of the mark captured by the camera module under standard atmospheric pressure;

[0014] A calculation module is configured to calculate a pressure value of the transparent display screen in a current environment based on a difference between the mark image information and the standard image information.

[0015] In a fourth aspect, the present application further provides an endoscope processing system, which comprises:

[0016] A second acquisition module is configured to acquire first image information collected by the camera module, wherein the first image information comprises at least environmental image information;

[0017] A display module is configured to display the first image information.

[0018] The technical solution adopted by the present application can achieve the following beneficial effects:

[0019] The insertion part, endoscope, intrarenal pressure detection system and endoscope processing system of the present application, when the distal end of the insertion part is in the intrarenal environment of the human body, is affected by the intrarenal pressure, the transparent display screen moves relative to the body of the insertion part, and this relative movement can include but is not limited to at least one of axial movement, attitude deflection or elastic deformation, so that the shape, size, etc. of the mark in the image information taken by the camera module changes accordingly, the current image information after the mark changes is recorded by the camera module, and the change of the mark can be quantified by image processing, so that the pressure value in the intrarenal environment can be calculated. This detection method does not need to embed a micro pressure sensor at the distal end of the insertion part, so as to effectively control the radial size of the distal end of the insertion part, while ensuring the passability of the distal end of the insertion part, the trauma risk can be significantly reduced; and since the transparent display screen is directly in the intrarenal environment, compared with the detection method of connecting the pressure sensor outside the body through the extension pipeline, the influence of factors such as pipeline length, flushing liquid flow resistance dynamic change and manual perfusion pressure fluctuation can be eliminated, the accuracy and timeliness of intrarenal pressure detection can be ensured;

[0020] At the same time, since the mark is displayed through the transparent display screen, the transparent display screen displays the mark only in the measurement state, and the transparent display screen is completely transparent in the non-measurement state, the measurement of intrarenal pressure can be carried out intermittently and frequently during the operation, and the transparent display screen in the non-measurement state will not block the surgical field, so that the surgeon can clearly observe the operation area, thereby avoiding the operation error caused by the mark blocking.

DETAILED DESCRIPTION

[0033] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0034] The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" and the like are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents a "or" relationship between the front and rear associated objects.

[0035] The present application will be described in detail below with reference to the accompanying drawings. Figures 1 to 9 ​​The insertion portion, the endoscope, the intrarenal pressure detection system and the endoscope processing system provided by the embodiments of the present application are described in detail through specific embodiments and application scenarios.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the insertion portion disclosed comprises an insertion portion body 100 and a transparent display screen 200, the transparent display screen 200 is movably arranged at the distal end of the insertion portion body 100, wherein the insertion portion body 100 can comprise an active bending section and a lens seat, the lens seat is installed and connected to the distal end of the active bending section, the active bending section can be one of a riveted snake bone, an integral cutting snake bone and an integral injection snake bone, the lens seat can provide a mounting basis for the distal end part of the camera module 110, the light source 120 and the instrument tube, that is, the distal end part of the camera module 110, the light source 120 and the instrument tube can be installed in the lens seat.

[0037] In the embodiments of the present application, the transparent display screen 200 is movably arranged at the distal end of the insertion portion body 100, when the distal end of the insertion portion body 100 is in the intrarenal environment, the transparent display screen 200 moves relative to the insertion portion body 100 under the influence of the intrarenal pressure. Exemplarily, the transparent display screen 200 can move axially relative to the insertion portion body 100 under the influence of the intrarenal pressure; or, the transparent display screen 200 can deflect in posture at the distal end of the insertion portion body 100 under the influence of the intrarenal pressure; or, the transparent display screen 200 can elastically deform at the distal end of the insertion portion body 100 under the influence of the intrarenal pressure. It can be understood that in the embodiments of the present application, the transparent display screen 200 is movably arranged at the insertion portion body 100, including but not limited to at least one of axial movement, posture deflection and elastic deformation.

[0038] In the embodiments of the present application, the transparent display screen 200 is used to display a mark 300, exemplarily, the insertion portion body 100 is provided with a camera module 110 and a window opening corresponding to the camera module 110, the camera module 110 can observe through the window opening, at least part of the transparent display screen 200 is located in the optical region of the window opening, and in the case that the transparent display screen 200 displays the mark 300, the mark 300 can be captured by the camera module 110.

[0039] Based on the above scheme, when the distal end of the insertion part is in the renal environment of the human body, the transparent display screen 200 is affected by the intrarenal pressure and moves relative to the insertion part body 100. This relative movement can include at least one of axial movement, attitude deflection, elastic deformation, or the like. The movement of the transparent display screen 200 changes the shape, size, and other characteristic information of the mark 300 displayed in the image information captured by the camera module 110. The camera module 110 captures and records the current image information of the mark 300 after the change, and the change of the mark 300 can be quantified through image processing, so that the pressure value of the transparent display screen 200 in the renal environment can be calculated, that is, the intrarenal pressure is measured.

[0040] At the same time, since the mark 300 is displayed by the transparent display screen 200, please refer to Figure 3 and Figure 4 , the mark 300 is displayed on the transparent display screen 200 only in the measurement state, please refer to Figure 2 , the transparent display screen 200 is completely transparent in the non-measurement state, and the measurement of the intrarenal pressure can be performed at intervals and multiple times. In this way, the transparent display screen 200 in the non-measurement state does not appear on the display device to block the surgical field, so that the surgeon can clearly observe the surgical area and avoid operation errors caused by the mark 300.

[0041] This detection method does not need to embed a micro pressure sensor at the distal end of the insertion part, so that the radial size of the distal end of the insertion part can be effectively controlled, the passability of the distal end of the insertion part is ensured, and the trauma risk can be significantly reduced. Moreover, since the transparent display screen 200 is directly in the renal environment and is affected by the intrarenal pressure to move relative to the insertion part body 100, compared with the detection method of connecting the pressure sensor outside the body through the extension pipeline, the influence of the pipeline length, the dynamic change of the flow resistance of the irrigation liquid, and the fluctuation of the manual perfusion pressure can be eliminated, and the accuracy and timeliness of the intrarenal pressure detection can be ensured.

[0042] In the embodiment of the present application, the transparent display screen 200 can be a rigid display screen or a flexible display screen. It can be understood that, in the case that the transparent display screen 200 is a rigid display screen, the transparent display screen 200 generally moves axially and / or deflects in posture in the intrarenal environment, and in the case that the transparent display screen 200 is a flexible display screen, the transparent display screen 200 can generally both move axially and / or deflect in posture and elastically deform in the intrarenal environment. Exemplarily, the conductive layer of the transparent display screen 200 in the embodiment of the present application can be an ITO electrode (indium tin oxide electrode), a graphene electrode, a silver nanowire electrode, and the like. The conductive layer deposited on a rigid substrate such as glass can make the transparent display screen 200 a rigid display screen, and the conductive layer deposited on a flexible substrate such as PET (polyethylene terephthalate) and PI (polyimide) can make the transparent display screen 200 a flexible display screen, which is not limited in the present application.

[0043] It should be noted that, in the embodiment of the present application, the insertion portion body 100 has a sealed cavity, which is distributed at the proximal end side of the transparent display screen 200 and corresponds to the camera module 110. Exemplarily, the sealed cavity can be located between the camera module 110 and the transparent display screen 200, the distal end side of the sealed cavity is sealed by the transparent display screen 200, and the proximal end side of the sealed cavity can be sealed by a transparent glass sheet to ensure that the camera module 110 can normally capture the mark 300 on the transparent display screen 200; or the camera module mounting cavity of the lens seat for mounting the camera module 110 can constitute the sealed cavity, the distal end side of the sealed cavity is sealed by the transparent display screen 200, and the proximal end side of the sealed cavity can be sealed by the injection glue. In this case, the distal end side of the transparent display screen 200 is exposed to the intrarenal environment, the proximal end side of the transparent display screen 200 is exposed to the sealed cavity, and the driving force of the dynamic change of the transparent display screen 200 relative to the insertion portion body 100 is derived from the pressure difference between the intrarenal environment and the sealed cavity, that is, the sealed cavity can provide a stable reference pressure to make the dynamic change of the transparent display screen 200 truly reflect the intrarenal pressure.

[0044] It can be understood that, if the sealed cavity leaks, the pressure difference between the intrarenal environment and the sealed cavity decreases, the "activity" of the transparent display screen 200 decreases, and thus the deformation amount of the mark 300 obtained by image information decreases, which further causes the mapping relationship between the deformation of the mark 300 and the intrarenal pressure to be invalid, that is, the real intrarenal pressure value cannot be accurately measured in this case.

[0045] In the embodiment of the present application, the transparent display screen 200 can be movably arranged at the distal end of the insertion portion body 100 by an elastic film. Specifically, please continue to refer to Figure 1The insertion part further comprises a first elastic film 500 connected to the outer side of the distal end of the insertion part body 100. The first elastic film 500 is made of high-transparency silicone or optical-grade epoxy resin. The first elastic film 500 is connected to the lens seat by gluing. The first elastic film 500 serves as the mounting base of the transparent display screen 200. The transparent display screen 200 is attached to the inner side of the first elastic film 500 by gluing. In the intrarenal pressure environment, the first elastic film 500 elastically deforms adaptively, causing the transparent display screen 200 to move axially, deflect, and elastically deform relative to the insertion part body 100. That is, the transparent display screen 200 is movable relative to the insertion part body 100, and the marker 300 changes to be captured and recorded by the camera module 110. At the same time, the first elastic film 500 is used as the bridging piece between the transparent display screen 200 and the insertion part body 100. The first elastic film 500 can elastically deform to fit the curved surface or irregular structure of the insertion part body 100 during installation, simplifying the assembly process of the entire insertion part.

[0046] In the embodiments of the present application, the first elastic film 500 comprises a base 510 and a connecting portion 520. The base 510 covers the distal end surface of the insertion part body 100. The connecting portion 520 is arranged around the base 510. The transparent display screen 200 is arranged on the base 510. The connecting portion 520 is connected and fixed to the insertion part body 100. The connecting portion 520 is sleeved on the radial outer side of the insertion part body 100 and is connected and fixed to the insertion part body 100 by gluing. That is, the first elastic film 500 is sleeved on the distal end of the insertion part body 100. It can be understood that, when the insertion part body 100 has an instrument channel, the base 510 is provided with a through hole corresponding to the instrument channel to facilitate the passage of the instrument for surgical operation.

[0047] In the related art, the insertion part body 100 usually further comprises a skin covering the outer side of the active bending section. The skin serves as a physical barrier to prevent body fluids and tissues in the human body from penetrating into the internal structure of the insertion part and damaging the mechanical parts or electronic elements of the insertion part.

[0048] Based on this kind of situation, in the further technical scheme, in the case that the insertion part body 100 has a skin, the skin can be wrapped on the outside of the connecting part 520, based on the wrapping effect of the skin, the edge peeling of the first elastic film 500 can be prevented in the process of bending, twisting or rubbing with the tissue of the insertion part body 100, and at the same time, the first elastic film 500 can also be prevented from being worn; at the same time, the skin can also be glued and fixed with the outside of the connecting part 520, so that the inside and outside of the connecting part 520 are glued and fixed, which can guarantee the stability of the connection of the first elastic film 500 and at the same time can play a good sealing effect on the distal end of the insertion part.

[0049] In some embodiments, the transparent display screen 200 is preferably a hard display screen. In this way, the transparent display screen 200 can maintain its own shape within a predetermined pressure range, thereby benefiting the reduction of changes in the geometric shape of the image information captured by the camera module 110. Specifically, the image distortion or stretching can be reduced. In this way, the tissue morphology in the image observed by the operator (usually a doctor) is more true, which is beneficial to improve the diagnostic accuracy and reduce the risk of surgical operation. In addition, after the transparent display screen 200 is set as a hard display screen, the transparent display screen 200 only changes in position, which is beneficial to simplify the difficulty of subsequent image processing, save image processing time, and thereby benefit the real-time performance of pressure detection. At the same time, the use of a hard display screen by the transparent display screen 200 makes the marker 300 only change in size and deflection attitude, and does not produce distortion and deformation, which can reduce the processing difficulty of image information in the later image processing process, and facilitate more accurate measurement of the pressure value of the intrarenal environment.

[0050] In the further technical scheme, in the case that the transparent display screen 200 is a hard display screen, the transparent display screen 200 covers the entire optical area of the window opening. With such a setting, the entire viewfinder window of the camera module 110 is covered by the hard transparent display screen 200, and there is no distortion area of the first elastic film 500 in the viewfinder window of the camera module 110, so that each local area of the image information captured by the camera module 110 has a high restoration degree, thereby guaranteeing the accuracy of clinical diagnosis by the doctor during the diagnosis and treatment process, reducing the risk of surgical operation, and also greatly reducing the difficulty of later image processing.

[0051] In an optional embodiment of the present application, the first elastic film 500 is provided with a hydrophilic coating. Exemplarily, the hydrophilic coating can be made of PEG (polyethylene glycol) or PVP (polyvinylpyrrolidone) material. The hydrophilic coating forms a uniform hydrogel layer on the surface of the first elastic film 500 by forming hydrogen bonds with water molecules. This structure can effectively repel non-polar contaminants such as blood proteins and lipids, reduce their adhesion and deposition pollution on the surface of the first elastic film 500, thereby ensuring the transparency of the first elastic film 500, and further ensuring the observation effect of the camera module 110, avoiding the situation that the observed human tissue and / or deformation markers are disturbed, thereby ensuring the effectiveness and accuracy of the camera module 110.

[0052] In an embodiment of the present application, the marker 300 can have various forms, for example, at least one of a linear marker, a curved marker, a ring-shaped marker, and a grid marker. In a preferred embodiment of the present application, the marker 300 can be a square ring-shaped marker or a circular ring-shaped marker. The axial symmetry design of the ring-shaped marker makes it have uniform changing response characteristics in the viewfinder window of the camera module 110 when it moves axially, that is, the ring-shaped marker in the viewfinder window deforms uniformly in the circumferential direction. This changing characteristic can simplify the model in the later quantification process, reduce the processing difficulty, and reflect the intrarenal pressure value in time. At the same time, when the first elastic film 500 is affected by the intrarenal pressure, even if the hard transparent display screen 200 deflects at a certain angle while the first elastic film 500 elastically deforms and moves axially, this deflection change can also be reflected by the marker 300, for example, the circular ring-shaped marker changes to an elliptical shape after deflection, and the square ring-shaped marker changes to a prismatic shape after deflection. This changing mode of the ring-shaped marker is beneficial to the later image correction process.

[0053] The inventors found in the research process that after the transparent display screen 200 is attached to the inner side of the first elastic film 500, due to the material difference between the transparent display screen 200 and the first elastic film 500, the edge of the transparent display screen 200 is prone to be separated from the first elastic film 500 with the elastic deformation of the first elastic film 500, and thus is prone to fall off, especially in the case of a hard display screen.

[0054] Based on this situation, in an embodiment of the present application, please refer to Figure 5The insertion portion can further include a second elastic film 600, which is distributed on the proximal side of the transparent display screen 200 and is attached to the proximal side of the transparent display screen 200. The second elastic film 600 has a smaller elasticity than the first elastic film 500, that is, the first elastic film 500 and the second elastic film 600 jointly hold the transparent display screen 200, and the second elastic film 600 is relatively harder than the first elastic film 500. In this way, the transparent display screen 200 can have a better attachment effect with the second elastic film 600. During the elastic deformation of the first elastic film 500 under pressure, the second elastic film 600 can apply a certain abutting force to the transparent display screen 200, so that the edge of the transparent display screen 200 can be in better abutting contact with the first elastic film 500, weakening the separation effect between the edge of the transparent display screen 200 and the first elastic film 500, thereby ensuring the stability and reliability of the connection between the transparent display screen 200 and the first elastic film 500.

[0055] In the embodiments of the present application, please refer to Figure 6 The insertion portion can further include a circuit board 400, and the camera module 110, the light source 120 and the transparent display screen 200 can be electrically connected to the circuit board 400. For example, the circuit board 400 can be a rigid circuit board or a flexible circuit board, and the present application does not make a specific limitation in this regard.

[0056] In the preferred embodiments of the present application, please continue to refer to Figure 6 The circuit board 400 can be a flexible circuit board, and the circuit board 400 is arranged to be bent on the insertion portion body 100 and has a portion distributed between the camera module 110 and the light source 120. In this way, the circuit board 400 can have a certain isolation effect on the light generated by the light source 120, so as to avoid the light source 120 directly irradiating the camera module 110 to generate glare or light spots in the image, thereby affecting the imaging effect.

[0057] In some embodiments of the present application, the mark 300 can be displayed on the display device after being photographed by the camera module 110. When performing a surgical operation, the doctor can roughly judge the pressure of each part in the visual field range through the real-time change of the mark 300, so as to consciously control the perfusion operation.

[0058] The embodiments of the present application also disclose an endoscope, which includes the insertion portion described above. For example, the endoscope further includes an operation handle, and the proximal end of the insertion portion is connected to the operation handle.

[0059] Please refer to Figure 7The embodiment of the present application also discloses a renal internal pressure detection system 700. The renal internal pressure detection system 700 is applied to the renal internal pressure detection by the insertion part. Specifically, the renal internal pressure detection system 700 comprises a first acquisition module 710, an identification module 720 and a calculation module 740, wherein:

[0060] The first acquisition module 710 is used for acquiring first image information collected by the camera module 110. The first image information comprises renal internal environment image information and marker image information. The renal internal environment image information can be transmitted to a display device for observation by a doctor, and the marker image information can be used for the measurement of the renal internal pressure.

[0061] The identification module 720 is used for identifying the marker image information of the marker 300 in the first image information. It can be understood that, in the process of identifying the marker image information, the identification module 720 identifies the marker image information including but not limited to the geometric shape information, the position information, the angle information, the size information, the stretching state information and / or the compression state information of the marker 300.

[0062] The calculation module 740 calculates the pressure value of the transparent display screen 200 in the current environment according to the marker image information. The pressure value is the renal internal pressure.

[0063] In a further technical solution, referring to Figure 8 The renal internal pressure detection system 700 can further comprise a comparison module 730. The comparison module 730 is used for comparing the marker image information with standard image information to determine the difference or difference value between the marker image information and the standard image information. The standard image information is the image information of the marker 300 captured by the camera module 110 under the standard atmospheric pressure. The standard image information includes but is not limited to the geometric shape information, the position information, the angle information, the size information, the stretching state information and / or the compression state information of the marker 300 under the standard atmospheric pressure.

[0064] In this case, the calculation module 740 can calculate the pressure value of the transparent display screen 200 in the current environment based on the difference value between the marker image information and the standard image information.

[0065] Of course, in the optional embodiment of the present application, a database corresponding to the image information of the marker 300 and the pressure information can be established in advance. In the renal internal pressure detection process, according to the current image information of the marker 300 acquired by the camera module 110, the marker 300 that is the same or closest to the current image information can be matched in the database. At this time, the pressure information corresponding to the marker 300 can be regarded as the pressure information in the renal internal environment.

[0066] The detection mode does not need to embed a micro pressure sensor at the distal end of the insertion part, so as to effectively control the radial size of the distal end of the insertion part, ensure the passability of the distal end of the insertion part, and significantly reduce the trauma risk; and since the transparent display screen is directly in the intrarenal environment, compared with the detection mode of connecting the pressure sensor outside the body through the extension pipeline, the influence of factors such as pipeline length, flushing liquid flow resistance dynamic change, and manual perfusion pressure fluctuation can be eliminated, and the accuracy and timeliness of intrarenal pressure detection can be ensured.

[0067] Please refer to Figure 9 The embodiment of the present application also discloses an endoscope processing system 800, and the disclosed endoscope processing system 800 can apply the aforementioned insertion part. Specifically, the endoscope processing system comprises:

[0068] A second acquisition module 810 is configured to acquire second image information collected by the camera module 110, and the camera module 110 is arranged at the distal end of the insertion part. The second image information at least includes intrarenal environment image information, and the second image information can also include marker image information.

[0069] A display module 820 is configured to display the second image information. In the measurement state, the display module 820 displays both the intrarenal environment image information and the marker image information. In the non-measurement state, the display module 820 only displays the intrarenal environment image information.
