In other words, the front side of any member refers to the side of the detection assembly 2 which is in the forward direction and the rear side of any member refers to the side of the detection assembly 2 which is in the backward direction.

The detection conductive material 111 and the detection wiring part 112 may be any materials that can realize electric conduction-directed soldering. Specifically, the detection conductive material 111 is connected with a conductive material on the detection assembly 2, and the detection wiring part 112 is connected with a detection wire of cables, the detection conductive material 111 can conduct with the detection wiring part 112. Therefore, signaling and/or power transmission between detection wires of cables and the detection circuit board 22 are achieved. The detection conductive material 111 and the detection wiring part 112 may be copper sheet for instance.
In a specific implementation process, the detection conductive materials 111 may be in parallel.
The main flexible plate of the FPC and the detection assembly of the present invention can prevent the cables and the detection assembly from direct soldering therebetween. In addition, comparing with soldering between wires, utilizing the detection conductive materials and the detection wiring parts on the main flexible plate favors enlarging soldering joints. Therefore, the present invention can reduce the difficulty of soldering operation, increase the strength and reliability of soldering joints and enhance the stability of electric conduction-directed soldering in various dynamic states.
In one of embodiments, the detection assembly 2 includes a detection member 21, wherein a wiring terminal of the detection member 21 is directly or indirectly connected with the main flexible plate for electric conduction. The detection member 21 is fixedly connected with the module base 3. By this embodiment, electric connection and component mounting can be achieved.
In a detailed example, the detection assembly 2 further includes a detection circuit board 22, a first conductive material (not shown in the figures) deposed on a first side of the detection circuit board 22, and a second conductive material 23 deposed on a second side of the detection circuit board 22.
The detection circuit board 22 is deposed in a vertical direction on a first side of the module base 3. The detection member 21 is deposed on a first side of the detection circuit board 22, and the wiring terminal of the detection member 21 is soldered to the first conductive material for electric conduction. The front side of the main flexible plate 11 is connected to the rear side of the detection circuit board 22. The detection conductive material 111 is soldered to the second conductive material 23 for electric conduction.
The design of the main flexible plate, the detection circuit board that is perpendicular to the main flexible plate, and the conductive material thereon prevents cables and the detection member from direct soldering. In addition, the detection member merely needs soldering to the first conductive material on the lateral side. Then is enlarged the solder points of the detection member. Therefore, the present invention can reduce the difficulty of soldering operation, increase the strength and reliability of soldering joints and enhance the stability of electric conduction-directed soldering in various dynamic states.
While a first side and a second side of the detection circuit board 22 may be planar, these sides may also be curved or circular arc in this embodiment.
The first conductive material may be any material that can realize electric conduction-directed connection, such as copper sheet. In one of embodiments, the first conductive material may be deposed on the surface of the detection circuit board 22. In alternate embodiments, the first conductive material may be deposed on a recess formed on the surface of the detection circuit board 22.
The second conductive material 23 may be any material that can realize electric conduction-directed connection, such as copper sheet. In one of embodiments, the second conductive material 23 may be deposed on the surface of the detection circuit board 22. In alternate embodiments, the second conductive material 23 may be deposed on a recess formed on the surface of the detection circuit board 22.
In one of embodiments, the detection member 21 and the module base 3 are bonded to each other with glue, and thus the detection member 21 and the module base 3 are bonded as a rigid body. By fastening the position of the detection assembly 2, connection strength between the detection member and the detection circuit board 22 is improved. Thus, separation of the detection member and the detection circuit board 22 is prevented.
In a detailed embodiment, the detection member 21 may include sensors, and the detection circuit board 22 may be a printed circuit board (PCB).
In one of embodiments, at least a portion of the outer edge of the detection circuit board 22 and at least a portion of the outer edge of the module base 3 are in the shape of a circular arc, matching the inner wall of the exterior tube. Furthermore, the detection circuit board 22 may be in the shape of a semicircular arc or an approximately semicircular structure.
In another embodiment, the detection member 21 may also be directly soldered to the main flexible plate 11 for electric conduction. For instance, the wiring terminal of the detection member 21 may be directly soldered to the detection conductive material 111 of the main flexible plate 11 for electric conduction. In the light of this embodiment, the detection circuit board 22 may not be used, and the detection member 21 may be bonded onto the module base 3 with glue.
In this embodiment, the exterior tube 6 may be connected to a flexible and controllable curved tube.
In one of embodiments, the exterior tube 6 may be filled with glue. With the glue, fixing between PCBs, members, and instruments is achieved, and the packaging of the entire device is done. “Filled with glue” can be understood as that no matter the exterior tube 6 filled with glue is fully or partly, the above-mentioned embodiments are applicable.
The detection member 21 may be an image capture member, and the detection assembly 2 may be an image capture assembly. In alternate embodiments, the detection member 21 may be a sensing device for detecting physical properties or chemical properties of liquid, gas, or solid, such as a liquid sensing device, a gas sensing device, etc.
The detection member 21 may be an image capture member. As having been developed rapidly, image sensors may have a miniature size of 0.7 mm*0.7 mm Therefore, there is an urgent demand for a package structure that is able to control the outer diameter, with lighting members, safe and reliable in package, and economical. The device provided by this embodiment and its alternatives exactly meet the requirement.
If the detection member 21 is a sensor, it may include a chip and a camera and may be in form of a cuboid structure, as shown in the figure. Besides, the detection member 21 may further include a detection member frame on which the sensor may be deposed.
To realize effective image capturing, the structure may utilize a lighting member 5 for illuminating, and the orientation of the lighting member 5 is identical to the orientation of the detection member 21.
In this embodiment, when two minor flexible plates 12 are bent to a desired position to facilitate installation of the lighting member 5, the two minor flexible plates 12 are respectively on a second side and a third side of the module base 3, which are opposite to each other. The minor flexible plates 12 and the main flexible plate 11 are flexible and may be configured to bend to each other. In an example, the aforementioned bending may be unidirectional or bidirectional. In an example, the aforementioned bending may be realized via designing the joints to be thinner structures. In another example, the flexible plates themselves are sufficient to realize bending, and additional structures suitable for bending are unnecessary. In other words, the minor flexible plate 12 may be understood as a part of the FPC which can be bent to the second side or the third side of the module base 3 for positioning and installing the lighting member 5.
In this embodiment, the end of the minor flexible plate 12 has the lighting member 5. Because the minor flexible plate 12 is connected with the main flexible plate 11, a position that is remote from the junction can be understood as the end of the minor flexible plate 12. The end of the minor flexible plate 12 is forwardly extended toward to a position approximating to the front side of the detection assembly 2.
With the minor flexible plate 12, the lighting member 5 is suitable to be deposed on the detection member 21 and thereby contributes sufficient and effective illuminating toward desired detection directions. The lighting member 5 and the detection member 21 may be planar on the same reference plane, which favors uniformly illuminating. The reference plane may be understood as a plane perpendicular to the desired detection direction.
The lighting member 5 may be any optical component that can output light, such as LED. The present invention does not limit that the lighting member 5 should output a specified color or should operate according to a specified principle. In a detailed embodiment, the lighting member 5 may project monochromatic light, dichromatic light, or light that changes color.
An adhesive sheet is applicable for deposing the lighting member 5 on the minor flexible plates 12, and more specifically, the adhesive sheet is deposed on the third plate body 123 of the minor flexible plates 12.
The bent LEDs are symmetrically arranged on the both sides of the detection member (such as sensor). In addition, the bent LEDs and the end of the detection member are on the same plane. In this way, uniform illumination is achieved.
In one of embodiments, the surface of the minor flexible plates 12 has illumination conductive materials (not shown in the figures). The illumination conductive materials are soldered to the lighting members 5 for electric conduction, and thereby two of the lighting members 5 are in parallel. The illumination conductive materials are also soldered to the illumination wires of cables for electric conduction via the illumination wiring part 113. The illumination wiring part 113 is deposed on the main flexible plate 11.
The illumination conductive material may be any material facilitating connection and electric conduction. Specifically, the illumination conductive material is a conductive material able to facilitate the connection and electric conduction with the lighting members 5 and the illumination wiring part 113. Therefore, signaling and/or power transmission between illumination wires of cables and the lighting members 5 are achieved. For instance, the conductive material for illuminating may be a metal sheet such as copper sheet. The illumination wiring part 113 may be any material able to facilitate soldering and electric conduction, such as copper sheet.
In one of the embodiments, the minor flexible plates 12 includes a first plate body 121 connected to the main flexible plate 11; a second plate body 122 connected to the front side of the first plate body 121; and a third plate body 123 connected to the front side of the second plate body 122. The lighting member 5 is deposed on the third plate body 123.
The first plate body 121 may be bent with respect to the main flexible plate 11; the second plate body 122 may be bent with respect to the first plate body 121; the third plate body 123 may be bent to the second plate body 122. The method to carry out the aforementioned bending may be in accordance with the bending between the main flexible plate 11 and the minor flexible plates 12 described hereinbefore.
When the first plate body 121, the second plate body 122, and the third plate body 123 are bend to desired positions, the first plate body 121 and the second plate body 122 of one of the minor flexible plates 12 are connect to the second side of the module base 3, and the first plate body 121 and the second plate body 122 of another one of the minor flexible plates 12 are connected to the third side of the module base 3. The third plate body 123 of the minor flexible plates 12 is positioned on the front side of the module base 3. In other words, the third plate body 123 extends to the outside of the module base 3.
When being bended to desired positions, the two third plate bodies 123 are deposed oppositely, and the two first plate bodies 121 are also deposed oppositely. In this way, it is guaranteed that two sides of the detection assembly 2 are symmetrical. Thus, the present invention can provide uniform illumination for detection.
In one of the embodiments, as shown in
When the FCP is not bent, the gap between the two first plate bodies 121 may be different from the gap between the two third plate bodies 123; for example, the gap between the two first plate bodies 121 is larger than the gap between the two third plate bodies 123. Thus, after the FCP is bent, this arrangement contributes causing position offset in a direction of the third plate bodies 123 corresponding to the first plate bodies 121, wherein the direction is perpendicular to the desired detection direction. For instance, after the third plate bodies 123 and the first plate bodies 121 have been bent to a desired position, a position offset is caused in a direction, wherein the direction is between the first plate bodies 121 and the corresponding third plate bodies 123 and is along from the fourth side of the module base 3 to the first side of that. In this way, the arrangement contributes making the lighting member 5 on the third plate body 123 closer to the detection assembly 2 and thereby provides precise and effective illuminating.

In the embodiment, therefore, by bending the FPC, the size of the package structure in radial direction is likely to be minimized. Specifically, the FPC may be understood as a FPC board having a thickness of 0.15 mm and being foldable. With FPC board, the packaged size in radial direction of the detection member and the lighting members is effectively controllable, required precision of size for manufacture and installation is facilitated, and durability to external force during installation is improved.
By utilizing FPC, this embodiment assures conductive connection favors carrying out assembly. In addition, because having flexibility, FPC is unlikely to suffer degrading of conductive connection caused by size error or external force and thereby improves the stability of conductive connection.

The detection positioning part 31 may include two positioning bosses extending externally. The gap between the two positioning bosses may match the corresponding-direction size of the detection member 21 so that the detection member 21 may pass through the gap between the two positioning bosses. Meantime, the gap between the two positioning bosses may be smaller than the corresponding-direction size of the detection circuit board 22 so that the detection circuit board will not pass through the gap. Therefore, with the detection positioning part 31, fastening the detection assembly 2 in a limited position is achieved.
The instrument tube channel 33 mentioned above may be any shape matching the instrument tube 4. The flexible plate channel 32 may be any structure channel which the detection member 12 may pass through.
With the above-mentioned design, the module base 3 may be an H-shaped structure, which may be made of metal. Referring an example shown in
Besides, the outer edge of the positioning bosses may be in the shape of a circular arc matching the exterior tube 6.
With the detection positioning part, the instrument tube channel, and the flexible plate channel formed on the module base, the following functions are achieved: simplifying installation; increasing positioning precision; and improving connection strength. Therefore, the installed detection member is unlikely to be affected by external force.
In embodiments, the main flexible plate 11 and/or the minor flexible plates 12 are bonded to the module base 3 with glue. Thus, even if the cables are pulled in axial direction, the connection strength is still reliable.
In one embodiment, the instrument tube 4 may be a flexible circular tube structure. After being installed in a metallic exterior tube and being fixed with glue together with other elements, the instrument tube 4 and those elements form an endoscope insertion unit. The cables may be multicore coaxial cables with shield layers. The shied layers may enhance soldering strength as well as exempt the cables from abnormalities.
The present invention also provides an in vivo detection apparatus, which comprises the aforementioned package structures of a detection and the aforementioned flexible and controllable curved tube. The detection package structure has an insertion member at one end thereof.
The insertion member and the controllable curved tube may respectively function as the insertion member and the controllable curved tube of the endoscope device.
In some embodiments of the present invention, the aforementioned structure and device and the modified structure thereof may be used to form a package of an insertion member of a micro sensor, wherein the packaged insertion member has a diameter of 2-10 mm. Thus is greatly expanded the application field of a micro sensor to the endoscope.
In conclusion, the present invention proposes a detection package structure and an in vivo detection apparatus, wherein the design of the main flexible plate and detection assembly on the FPC can prevent the cables from being directly soldered to the detection assembly, and wherein the detection conductive material of the main flexible plate and the detection wiring part are used to implement soldering. In comparison with the cable-to-cable soldering technology, the present invention favors enlarging soldering spots. Therefore, the present invention can lower the difficulty of soldering operation, enhance the strength and reliability of soldering, and promote the stability of the electric conduction-directed soldering in various dynamic states.
Meanwhile, the FPC used by the present invention can guarantee electric connection as well as convenience assemblage. The FPC has flexibility. Therefore, dimensional errors or external force are less likely to affect the performance of electric-conduction-directed soldering. Thus is further improved the stability of electric conduction-directed soldering.
