Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to capsule endoscope devices. Background Technology

[0002] Currently, existing technologies use endoscopic intubation to aspirate fluid from the endoscopic cavity for testing. The main problem is that the outer diameter of the endoscopic intubation is too large, causing discomfort to the examiner.

[0003] Another approach uses capsule endoscopes, which are flexible, small-diameter tubes. Liquid is directly aspirated from the tip of the flexible tube using a syringe or negative pressure device. However, this method is prone to blockage because the tube is flexible and relatively long; direct external negative pressure sampling can easily cause the tube to close, resulting in sampling failure. Furthermore, the flexible tube wall is susceptible to deformation, which can also block the tube. This method suffers from low sampling efficiency and low success rate. Therefore, it is necessary to research a capsule endoscope device to address these problems. Summary of the Invention

Detailed Implementation

[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0038] The terms "comprising" and "having," and any variations thereof, used in this invention are intended to cover non-exclusive inclusion. References to "embodiment" herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] Combination Figure 1 As shown, this invention mainly relates to a capsule endoscope device, including a capsule endoscope and a connecting component connected to the capsule endoscope. In this embodiment, the capsule endoscope is inserted into a designated area or near a lesion in the digestive tract by oral administration by the patient. One end of the connecting component is connected to the capsule endoscope, and the other end of the connecting component extends away from the capsule endoscope. During sampling, the other end of the connecting component is positioned outside the body.

[0040] Combination Figure 1 As shown, in this embodiment, the capsule endoscope includes a housing 1, on which a sampling port communicating with the inside and outside of the housing 1 is provided. The sampling port penetrates through the inner and outer walls of the housing 1. The housing 1 is made of a biocompatible material that is not corroded by digestive fluids, allowing it to be used directly exposed to internal organs, ensuring the patient's health.

[0041] The connecting assembly extends from the outside of the housing 1 in a direction away from the housing 1. The connecting assembly includes a connector 5 with a hollow inner cavity 51 disposed on the outer wall of the housing 1, a pump 6 disposed within the hollow inner cavity 51, and a connecting pipe 7 disposed on the side of the connector 5 away from the housing 1. A portion of the housing 1 is accommodated within the hollow inner cavity 51 to connect with the inner wall of the connector 5. During sampling, the end of the connecting pipe 7 away from the connector 5 is positioned externally.

[0042] Combination Figure 2 As shown, in this embodiment, preferably, the hollow inner cavity 51 is provided with an opening on the side near the shell 1, so that a part of the shell 1 can be accommodated in the hollow inner cavity 51 through the opening of the hollow inner cavity 51.

[0043] The pump 6 is fixed to the inner wall of the connector 5, or fixed to the inner wall of the connector 5 by means of an installation component. The connecting pipe 7 can be fixed to the connector 5 by adhesive, or the connector 5 and the connecting pipe 7 can be integrally formed by a molding process.

[0044] By placing the pump 6 inside the connector 5 outside the housing 1, this invention reduces the size of the capsule endoscope, making it easier for patients to swallow and improving their experience. Furthermore, since the pump 6 is located upstream of the liquid flow in the connecting tube 7, its normal operation will not clog the connecting tube 7, thereby improving sampling efficiency and success rate.

[0045] The connecting tube 7 is elongated so that the end of the connecting tube 7 away from the fixed part is placed outside the body during sampling, so that the collected liquid can be transported outside the body.

[0046] The pump 6 includes a pump inlet 621 in fluid communication with the sampling port and a pump outlet 631 in fluid communication with the connecting pipe 7. The connecting pipe 7 includes a liquid outlet channel 71 connecting the pump outlet 631 and the outside of the connecting pipe 7. Preferably, the pump inlet 621 is disposed towards the housing 1 and the pump outlet 631 is disposed towards the connecting pipe 7, so as to simplify the connection between the pump inlet 621 and the sampling port and the pump outlet 631 and the connecting pipe 7, respectively.

[0047] When the capsule endoscope operates within the human digestive tract, the medium can be a liquid located within the digestive tract. When pump 6 operates, it generates negative pressure, causing the medium outside the capsule endoscope to enter the interior of pump 6 through the sampling port and pump inlet 621 under pressure. Subsequently, pump 6 generates positive pressure, causing the medium inside pump 6 to exit the body through pump outlet 631 and liquid outlet channel 71 under pressure, thus achieving the purpose of directly collecting liquid from the body and transporting the collected liquid to the outside through the connecting assembly.

[0048] Preferably, the outer diameter of the capsule endoscope is less than 11.6 mm, and the axial length of the capsule endoscope is less than 33 mm.

[0049] Preferably, pump 6 is a micro pump to reduce the installation space required for pump 6.

[0050] Furthermore, the housing 1 includes a first end 14 and a second end 15 disposed opposite each other along the axial direction of the housing 1. The connector 5 is sleeved on the outside of the second end 15 along the axial direction of the housing 1. That is, the axis of the connector 5 is coincident with the axis of the housing 1 to improve the structural balance of the capsule endoscope device.

[0051] Preferably, the connector 5 is configured as a sleeve that is interference-fitted onto the outer side of the second end 15. The sleeve and the outer side of the second end 15 are fixed to each other due to friction.

[0052] Combination Figure 3 As shown, in this embodiment, the pump 6 is positioned near the second end 15. The housing 1 includes a housing outlet 13 located at the second end 15, allowing fluid communication between the sampling port and the pump inlet 621. The housing outlet 13 penetrates both the inner and outer walls of the housing 1, and its placement facilitates the flow of liquid from the sampling port through the interior of the housing 1 before entering the pump 6. Preferably, the housing outlet 13 is located at the center of the second end 15.

[0053] Furthermore, the first end 14 is an arc segment, and the second end 15 is a planar segment opposite to the arc segment.

[0054] Preferably, the housing outlet 13 is housed within the hollow inner cavity 51. It is understood that the housing outlet 13 can be directly connected to the pump inlet 621, or a pipe structure can be provided between the housing outlet 13 and the pump inlet 621.

[0055] Combination Figure 4 As shown, the pump 6 further includes a pump body 61 fixed to the inner wall of the connector 5. The pump body 61 has a pump inlet 621 on one side facing the second end 15 and a pump outlet 631 on the other side.

[0056] Pump inlet 621 and pump outlet 631 are respectively located on opposite sides of pump body 61, so that liquid can enter from one side of pump body 61 and exit from the other side. One side of pump body 61 faces the second end 15, and the other side of pump body 61 faces the connecting pipe 7, so that the flow of fluid is smoother, so that pump 6 can work normally. At the same time, the wall of connecting pipe 7 is not easily deformed, so as not to block the liquid outlet channel 71 of connecting pipe 7, thereby improving the sampling success rate.

[0057] Furthermore, the pump body 61 is provided with a vent hole 611 that penetrates one side and the other side of the pump body 61. The vent hole 611 connects the opposite sides of the pump body 61, wherein a predetermined gap is provided between the pump body 61 and the second end 15 to facilitate the passage of gas through the vent hole 611.

[0058] The connecting pipe 7 also includes a connecting channel 72 that connects the hollow inner cavity 51 to the outside of the connecting pipe 7. The hollow inner cavity 51 connects the connecting channel 72 to the vent 611. Gas outside the connecting pipe 7 can enter through the connecting channel 72, the hollow inner cavity 51, and the vent 611, while gas inside the hollow inner cavity 51 can be discharged to the outside of the connecting pipe 7 through the vent 611, the hollow inner cavity 51, and the connecting channel 72.

[0059] The connection channel 72 can be used to assemble the wires for an external power supply, which can enable the pump 6 to operate, thereby saving battery power of the capsule endoscope.

[0060] Furthermore, when the connector 5 is interference-fitted onto the outside of the second end 15, an external positive and negative pressure device draws gas from the hollow inner cavity 51 through the connecting channel 72 and the vent 611, thereby creating a negative pressure between the connector 5 and the capsule endoscope, increasing the connection strength between them. When it is necessary to detach the capsule endoscope from the connector 5, gas can be injected into the hollow inner cavity 51 through the connecting channel 72 and the vent 611. The injected gas increases the air pressure between the connector 5 and the capsule endoscope, so that the positive pressure of the gas is greater than the frictional force, releasing the capsule endoscope.

[0061] The connecting channel 72 and the liquid outlet channel 71 are respectively arranged to extend along the axis parallel to the connecting pipe 7.

[0062] Furthermore, the pump 6 also includes a circuit board 64 fixed to the inner wall of the connector 5. The circuit board 64 controls the operation of the pump body 61. The circuit board 64 and the pump body 61 are arranged adjacent to each other in the radial direction along the connector 5.

[0063] The surface of the circuit board 64 facing the second end 15 is flush with the surface of the pump body 61 facing the second end 15, and together they form a circle. This reduces the installation space of the pump 6 and the axial length of the capsule endoscope device.

[0064] Another implementation of the vent 611 is that the circuit board 64 and the pump body 61 together form the vent 611, and the number of vent 611 can be set to multiple.

[0065] Furthermore, an inlet pipe 62 for forming a pump inlet 621 is provided on one side of the pump body 61. The inlet pipe 62 protrudes into the housing 1 through the housing outlet 13. The inlet pipe 62 extends from the pump body 61 toward the second end 15 and protrudes into the housing 1 through the housing outlet 13 to communicate with the sampling port in fluid.

[0066] The capsule endoscope also includes a flexible tube 18 disposed within the housing 1 and connecting the sampling port and the inlet tube 62. Preferably, the junction of the inlet tube 62 and the flexible tube 18 is located at the housing outlet 13.

[0067] Furthermore, the flexible tube 18 is interference-fitted onto the outer wall of the inlet tube 62. The flexible tube 18 extends from the sampling port towards the inlet tube 62. Understandably, the flexible tube 18 can also be fixed to the outside of the inlet tube 62 with adhesive.

[0068] In this embodiment, the flexible tube 18 extends from the sampling port in a direction parallel to the axis of the housing 1 and then in a direction parallel to the diameter of the housing 1. The flexible tube 18 makes full use of the gap between the inner wall of the housing 1 and the equipment components disposed within the housing 1.

[0069] Furthermore, an outlet pipe 63 forming a pump outlet 631 is provided on the other side of the pump body 61, and the outlet pipe 63 extends into the liquid outlet channel 71. The outlet pipe 63 extends from the pump body 61 toward the connecting pipe 7, wherein the outer wall of the outlet pipe 63 is interference-fitted with the inner wall of the liquid outlet channel 71.

[0070] Preferably, the connecting pipe 7 comprises a flexible material. The inner wall of the liquid outlet channel 71 formed by the flexible material is fitted onto the outer wall of the outlet pipe 63. Of course, the inner wall of the liquid outlet channel 71 formed by the flexible material can also be fixed to the outer wall of the outlet pipe 63 with adhesive.

[0071] Under pressure, the liquid outside the capsule endoscope enters the pump 6 through the sampling port, flexible tube 18, and inlet tube 62. After the liquid enters the pump 6, the pump 6 generates positive pressure, and the medium inside the pump 6 reaches the outside through the outlet tube 63 and liquid outlet channel 71 under pressure, so as to achieve the purpose of directly collecting liquid from the body and transporting the collected liquid to the outside through the connecting assembly.

[0072] Furthermore, the sleeve and the housing 1 can also be glued together or fixed to the housing 1 by means of threaded connection.

[0073] Furthermore, the capsule endoscope device also includes a connector seat disposed within the sleeve and magnetically adsorbing the capsule endoscope. The connector seat is fixed inside the sleeve and is magnetically attracted to the capsule endoscope, thereby limiting the axial displacement of the capsule endoscope within the sleeve. The sleeve and the capsule endoscope are connected not only by negative pressure but also by magnetic attraction; this dual force enhances the connection strength between the sleeve and the capsule endoscope.

[0074] Furthermore, the capsule endoscope also includes a camera component 2 disposed within the housing 1 and near the first end 14, with the sampling port disposed within the field of view of the camera component 2.

[0075] The housing 1 also includes a transparent portion disposed within the field of view of the camera assembly 2. The housing 1 is at least partially made of a transparent material, which is at least partially disposed within the field of view of the camera assembly 2. It is understood that the housing 1 may be entirely made of a transparent material.

[0076] The camera component 2 observes the exterior of the shell 1 through the transparent part. When the capsule endoscope is located in the digestive tract, the operator can perform digestive tract examinations, digestive interval segmentation, and other actions through the images captured by the camera component 2. After confirming that the sampling capsule has reached the designated area or near the lesion in the digestive tract, the operator can then decide whether to start sampling, thus realizing the "visualization of the digestive tract" of the sampling capsule.

[0077] Furthermore, the camera assembly 2 includes a front camera 21 disposed along the axial direction of the housing 1 toward the first end 14. To ensure a wide-angle view, the front camera 21 is spaced a certain distance from the first end 14. Preferably, the axis of the front camera 21 coincides with the axis of the housing 1 to improve the structural balance of the housing 1, thus providing the advantage of structural stability and reliability.

[0078] The sampling port includes a front sampling port 11 located within the field of view of the front camera 21. The front camera 21 can monitor the sampling status of the front sampling port 11 in real time, providing the advantage of visualizing the sampling process.

[0079] Combination Figure 5 As shown, the camera assembly 2 also includes a side camera 22 disposed radially toward the outside of the housing 1. The sampling port includes a side sampling port 12 disposed within the field of view of the side camera 22. The side sampling port 12 is disposed near the middle of the inner wall of the housing 1.

[0080] By simultaneously setting up a front sampling port 11 and a side sampling port 12, the sampling speed of the capsule endoscope can be increased, and the area of ​​the sampling region can be increased.

[0081] Furthermore, the number of side cameras 22 is set to multiple, and the multiple side cameras 22 are arranged circumferentially with the axis of the housing 1 as the center.

[0082] In this embodiment, the camera assembly 2 may include only the front camera 21, only the side camera 22, or both. When the camera assembly 2 includes both the front camera 21 and the side camera 22, the field of view of the capsule endoscope can at least cover the front and sides of the housing 1 without rotating the capsule endoscope, thus obtaining a wider field of view and improving the patient's user experience.

[0083] Furthermore, when the camera assembly 2 includes a front camera 21 and a side camera 22, the capsule endoscope can be provided with two flexible tubes 18 that connect to the front sampling port 11 and the side sampling port 12, respectively. The pump inlet 621 is provided with interfaces that connect to the two flexible tubes 18.

[0084] Furthermore, the capsule endoscope also includes a positioning component 31 and a magnetic component 32 respectively disposed within the housing 1.

[0085] The camera assembly 2, the positioning component 31, and the magnetic component 32 are arranged sequentially along the direction from near the first end 14 to away from the second end 15.

[0086] The positioning component 31 is used to monitor the position of the housing 1, and the magnetic component 32 is configured to move the housing 1 under the action of an external magnetic field. Preferably, the positioning component 31 is a position sensor, and the magnetic component 32 is a magnet.

[0087] In this embodiment, there is no need to install a drive mechanism inside the housing 1. Instead, the magnetic component 32 is driven to rotate or move by the external magnetic field force of the external device, thereby driving the capsule endoscope to a designated area or near the lesion in the digestive tract. This has the advantage of reducing the internal volume of the housing 1. The cooperation between the positioning component 31 and the magnetic component 32 makes the capsule endoscope actively controllable under the control of the external device, thus enabling the capsule endoscope to be dragged into a designated area or near the lesion in the digestive tract.

[0088] Furthermore, the capsule endoscope also includes a battery 4 disposed within the housing 1. The camera assembly 2, positioning component 31, magnetic component 32, and battery 4 are arranged sequentially along the axial direction of the housing 1 to reduce the radial length of the housing 1. The battery 4 provides power to the capsule endoscope.

[0089] Furthermore, the housing 1 includes a transparent housing 16 and a non-transparent housing 17 that are interconnected. The transparent housing 16 and the non-transparent housing 17 together define the inner cavity of the housing 1. The transparent housing 16 and the non-transparent housing 17 are fixedly connected. Specifically, the transparent housing 16 and the non-transparent housing 17 are fixed by adhesive bonding. Of course, in other embodiments, the transparent housing 16 and the non-transparent housing 17 can also be fixed by threaded connection or snap-fit, etc., which will not be described in detail here. The transparent housing 16 and the non-transparent housing 17 are each formed into a hollow structure.

[0090] The first end 14 is an arc segment, and the second end 15 is a planar segment. The transparent shell 16 includes an arc segment and a first vertical segment extending from the arc segment to the planar segment.

[0091] refer to Figure 6 As shown, the area of ​​view of the front camera 21 is Figure 6 The area between the two dotted lines. The first arc segment or the first arc segment together with at least part of the first vertical segment forms a transparent portion within the field of view of the front camera 21.

[0092] The non-transparent shell 17 includes a planar segment and a second vertical segment extending from the planar segment to an arc segment. The connection between the planar segment and the second vertical segment is an arc transition connection. The first vertical segment and the second vertical segment are fixed by adhesive bonding to achieve a fixed connection between the transparent shell 16 and the non-transparent shell 17.

[0093] The operation method of the capsule endoscope device provided by the present invention:

[0094] 1. Fix connector 5 onto the capsule endoscope;

[0095] 2. The patient swallowed a capsule endoscope;

[0096] 3. The positioning component 31 provides timely feedback on the position of the capsule endoscope, and the external device controls the magnetic component 32 to drive the capsule endoscope to a designated area in the digestive tract or near the lesion.

[0097] 4. External equipment controls the capsule's orientation, ensuring the sampling port is submerged below the surface of the digestive tract fluid;

[0098] 5. Connect the power supply and start pump 6;

[0099] 6. Pump 6 draws the liquid out of the body through the liquid outlet channel 71 and collects it;

[0100] 7. After collection, positive pressure is injected through the connecting channel 72 and the vent 611 using an external positive and negative pressure device; since the positive pressure is greater than the friction force, the connector 5 is disengaged from the capsule endoscope.

[0101] 8. After sampling is completed, the capsule endoscope continues to take pictures and conduct tests inside the body.

[0102] Compared to existing technologies, the capsule endoscope device provided by this invention is connected to the capsule endoscope via a connecting assembly. The pump 6 is housed within the connecting member 5 outside the housing 1, reducing the volume of the capsule endoscope. The sampling port on the housing 1 is fluidly connected to the pump inlet 621. The connecting tube 7 includes a liquid outlet channel 71 connecting the pump outlet 631 to the outside of the connecting tube 7, enabling direct collection of liquid from the body and delivery of the collected liquid to the outside via the connecting assembly. Furthermore, this sampling method eliminates the need for a sampling chamber inside the capsule endoscope, further reducing its volume. The pump 6 is positioned upstream of the liquid flow within the connecting tube 7, ensuring that normal operation of the pump 6 does not clog the connecting tube 7, thereby improving sampling efficiency and success rate. This device offers advantages such as small size, ease of swallowing, high sampling efficiency, and high sampling success rate.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
