Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a camera device and an endoscope. Background Technology

[0002] Endoscopes are widely used medical diagnostic tools in recent years. An endoscope has a camera device installed at the tip of its insertion section inside the patient's body. This camera device has an image sensor that converts light passing through the lens assembly into image information. This image information is then transmitted to the endoscope's main unit via the camera device's base plate and the camera cable connected to the base plate for image processing.

[0003] Currently, when connecting the camera cable to the substrate, part of the outer sheath of the camera cable is cut off to expose the inner core of the cable composed of multiple signal lines, and the multiple signal lines are soldered to the corresponding positions on the substrate.

[0004] However, during actual use, the endoscope tip is bent. When the endoscope bends, the internal tubing and camera cable move relatively linearly. After repeated movement, the outer sheath of the camera cable may not completely cover the inner core, thus failing to protect it and causing the inner core to break. In severe cases, this can lead to interruption of image transmission, preventing the endoscope from displaying images correctly and posing a significant safety hazard to the patient.

[0005] Furthermore, the outer sheath of camera cables is generally made of fluoropolymer plastics, which have lubricating properties. This results in poor bonding strength with adhesives such as epoxy resins. To improve adhesion, current technology uses activation equipment to pre-treat the bonding area; however, this activation process has time limitations, causing difficulties in endoscopic assembly. Additionally, other chemical corrosion treatments can damage the cable sheath, leading to breakage. Therefore, the problem of securing the outer sheath of camera cables remains. Utility Model Content

[0006] In order to solve at least one of the problems existing in the prior art, the present invention proposes a camera device and an endoscope, the purpose of which is to reliably fix the outer sheath of the camera cable so that the outer sheath can fully protect the inner core of the cable and prevent the inner core of the cable from breaking.

[0007] To achieve the above objectives, one embodiment of the present invention is a camera device, characterized in that it includes: a housing; a substrate disposed within the housing; and a camera cable including a cable core and a cable sheath, the cable core being connected to the substrate, the cable sheath including a first sheath covering the outer peripheral surface of the cable core and a second sheath connected to the first sheath and peeled off from the outer peripheral surface of the cable core, a first fixing member being disposed on the first sheath near the second sheath, the second sheath being divided into multiple segments, at least one segment being retained, and one or more segments of the second sheath being retained being fixed to the substrate and / or the housing.

[0008] Preferably, the second outer skin is fixed to the substrate by a second fixing member.

[0009] Preferably, the substrate is provided with a groove, and the second outer skin is fixed in the groove by the second fixing member.

[0010] Preferably, the interior of the outer shell is filled with an adhesive, and the second outer skin is bonded and fixed to the adhesive or formed as a single unit.

[0011] Preferably, the second outer skin is fixed to the outer surface of the outer shell by a third fixing member.

[0012] Preferably, the outer shell is provided with an outer diameter deformation portion, and the second outer skin is fixed to the outer diameter deformation portion by the third fixing member.

[0013] Preferably, the outer casing also has a through hole, through which the tip of the second outer skin enters the interior of the outer casing from the outside of the outer casing and is fixed inside the outer casing.

[0014] Preferably, the top of the second outer skin emerges from the inside of the outer shell through a through hole and is fixed to the outer diameter deformation portion.

[0015] Preferably, the first fixing member is located inside the housing.

[0016] On the other hand, one embodiment of this utility model is an endoscope having any of the above-mentioned imaging devices.

[0017] Preferably, the endoscope includes: an insertion portion,

[0018] The front end is located on the front end side of the insertion part;

[0019] A snake-bone connecting ring is provided at the front end. The snake-bone connecting ring is closer to the front end of the insertion part than the first fixing member. The snake-bone connecting ring extends axially at one end near the base end and covers the first fixing member.

[0020] According to the camera device and endoscope of this utility model, part of the outer sheath is torn into multiple pieces to expose the inner core of the cable. The second outer sheath, which is torn into multiple pieces, is not cut off. The previously discarded second outer sheath is used to fix the cable outer sheath to the outer shell and / or circuit board of the camera device. This can increase the fixing length of the cable outer sheath, thereby improving the fixing reliability, and can also improve material utilization and be more environmentally friendly. Furthermore, the first fixing member set near the second outer sheath of the first outer sheath can prevent the first outer sheath from being further peeled from the inner core of the cable when the second outer sheath is under force. The second outer sheath, which is divided into multiple pieces, can increase the fixing contact area during fixing, further improving the fixing reliability and preventing the inner core of the cable from breaking.

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0033] The imaging device of this embodiment will now be described in detail with reference to the accompanying drawings. Furthermore, in this embodiment, as shown in the drawings, the tip of the insertion part near the patient's body is referred to as the front end direction, and the side near the operating part is referred to as the base end direction.

[0034] like Figure 1 As shown, the imaging device includes components such as a lens assembly 1, an image sensor (not shown), a lens base 2, a housing 3, a substrate 4, and an imaging cable 5. The lens assembly 1 is fixedly connected to the lens base 2. Furthermore, the lens base 2 and the housing 3 cooperate to form a sealed space, within which the image sensor is fixed on the lens base 2. The image sensor converts light incident from the lens assembly 1 into image information and transmits the image information to the substrate 4 disposed inside the housing 3. In addition, the lens assembly 1, the lens base 2, the housing 3, and the substrate 4 are fixed inside the tip (not shown) located at the top of the insertion section of the endoscope.

[0035] The camera cable 5 includes a cable core 51 and a cable sheath. The cable core 51 is inserted into the housing 3 and connected to the substrate 4 by means of soldering or other methods. Furthermore, the camera cable 5 is disposed inside the insertion part of the endoscope, extends along the insertion part, and connects to the endoscope host via the operating part, endoscope connector, etc., to further transmit the image information received by the substrate 4 to the endoscope host for image processing.

[0036] like Figure 1As shown, the outer sheath of the camera cable 5 includes a first outer sheath 52 and a second outer sheath 53. The first outer sheath 52 covers the outer peripheral surface of the cable core 51 and fits tightly against the cable core 51, providing protection for the cable core 51. The second outer sheath 53 is connected to the first outer sheath 52 and is peeled off from the outer surface of the cable core 51. A first fixing member 61 is provided at a position of the first outer sheath 52 near the second outer sheath 53.

[0037] The second outer sheath 53 is divided into multiple segments (at least two segments), and at least one segment of the divided second outer sheath 53 is fixed to the substrate 4 and / or the outer shell 3. That is, in this embodiment, the second outer sheath 53 stripped from the inner core 51 is retained on the camera cable 5, and the second outer sheath 53 is divided into multiple segments, and at least one segment of the divided second outer sheath 53 is fixed to the camera cable 5.

[0038] This increases the fixed length and contact area of ​​the cable sheath, thus reliably securing the camera cable 5. Even if the endoscope tip bends and the camera cable 5 moves, this movement will be absorbed by the second sheath 53. Furthermore, the first fixing member 61 ensures that the first sheath 52 reliably covers the cable core 51, preventing relative movement between the first sheath 52 and the cable core 51. Simultaneously, when the second sheath 53 is subjected to force, it also prevents the first sheath 52, which is connected to the second sheath 53, from peeling off from the cable core 51, providing more reliable protection for the cable core 51. This prevents the first sheath 52 protecting the cable core 51 from peeling or being damaged, and prevents the cable core 51 from breaking.

[0039] Furthermore, if only one segment of the peeled second outer skin 53 is retained, the remaining excess portion can be discarded.

[0040] The length of the second outer sheath 53 can be set as needed, as long as it can be fixed to the substrate 4 and / or the outer shell 3. If the length of the second outer sheath 53 is insufficient, part of the inner core 51 of the cable can be cut to extend the second outer sheath 53. After the inner core 51 of the cable and the substrate 4 are soldered, the length of the second outer sheath 53 can be covered inside the outer shell 2.

[0041] The first fixing member 61 can be made of materials such as thread or cable ties. An adhesive can also be applied to the outside of the first fixing member 61 to further improve the fixing effect.

[0042] Specifically, such as Figure 1 As shown, the second outer skin 53 can be fixed to the base plate 4 by the second fixing member 62. The second fixing member 62 can be made of wire, cable tie, etc. The second fixing member 62 can firmly fix the second outer skin 53 to the base plate 4.

[0043] The camera cable 5 may retain a second outer sheath 53, which is stripped from the outer surface of the inner core 51 into multiple segments, or only one segment may be retained for fixing the camera cable 5.

[0044] Preferably, the multi-lobed second outer sheath 53 are wrapped around the outer surface of the substrate 4 at approximately equal distances, thereby effectively protecting the cable core 51 from multiple directions and improving the reliability of the connection between the cable core 51 and the substrate 4.

[0045] Furthermore, in this embodiment, a groove 41 can be provided on the substrate 4, and the second outer skin 53 is fixed to the groove 41 of the substrate 4 by the second fixing member 62. This can further improve the reliability of the fixing.

[0046] In addition, in this embodiment, an adhesive such as epoxy resin can be filled inside the outer casing 3, and the second outer skin 53 is integrally formed with the adhesive, thereby fixing the second outer skin 53 inside the outer casing 3. When the second outer skin 53 is divided into multiple petals and remains as multiple petals, the second outer skin 53 can be integrally formed with the adhesive by intertwining, twisting in various directions, etc. Therefore, even if the second outer skin 53 is made of fluoroplastic material, the second outer skin 53 can be reliably fixed in a simple manner.

[0047] Furthermore, the above-mentioned fixing methods can also be combined. For example, after the second outer skin 53 is fixed to the groove 41 of the substrate 4 by the second fixing member 62, the adhesive can be poured into the interior of the outer shell 3 to bond and fix the second outer skin 53 with the adhesive or form it as a whole, thereby obtaining a more secure fixing effect.

[0048] like Figure 3 As shown, in another example of this embodiment, the housing 3 includes a housing body 31 and a cable channel 32 protruding from the housing body 31 toward the base end. On the outer surface of the channel wall of the cable channel 32, an outer diameter deformation portion 33 is formed by providing protrusions or etching.

[0049] Next, as Figure 4 As shown, the second outer skin 53 is fixed to the outer surface of the outer shell 3 by the third fixing member 63. The third fixing member 63 can be the same as the second fixing member 62, and can be made of thread, cable ties, etc. In this way, the second outer skin 53 can also be reliably fixed.

[0050] Specifically, the outer diameter deformation portion 33 is fixed to the outer surface of the cable channel 32. By providing the outer diameter deformation portion 33, the third fixing member 63 can more tightly bind the second outer sheath 53 to the outer casing 3, further providing the reliability of the fixation.

[0051] The outer diameter deformation part 33 has a feature of changing outer diameter on the base end side relative to the insertion direction of the endoscope. It can be configured as a groove fixing structure, a flange fixing structure, a convex dot array fixing structure, a combined fixing structure, etc., so that the second outer skin 53 can be more tightly bound to the outer shell 3 through the outer diameter deformation part 33.

[0052] Preferably, the multi-lobed second outer sheath 53 is wrapped around the outer surface of the cable channel 32 and fixed with approximately equal spacing between them. This protects the cable core 51 from all directions and improves the reliability of the connection between the cable core 51 and the substrate 4.

[0053] In addition, after the second outer skin 53 is fixed to the outer diameter deformation portion 33 by the third fixing member 63, an adhesive can be filled into the outer diameter deformation portion 33 to bond and fix the second outer skin 53 to the adhesive or to make the two into one, thereby further improving the reliability of the fixation.

[0054] like Figure 5 As shown, in this embodiment, when viewing the housing 3 from the base to the front, the projection of the cable channel 32 is completely within the projection range of the housing body 31. Therefore, even if a second outer sheath 32 is fixed to the outer surface of the cable channel 32, the maximum radial dimension of the housing 3 will not increase, and the installation of the camera device will not be hindered.

[0055] In addition, although Figure 4 The diagram shows the second outer sheath 53 fixed to the outer surface of the channel wall of the cable channel 32. However, the second outer sheath 53 can also be fixed to the outer surface of the outer shell body 31. Alternatively, an outer diameter deformation part can be provided on the outer surface of the outer shell body 31, or no outer diameter deformation part can be provided.

[0056] like Figure 6 As shown, in another example of this embodiment, the outer casing 3 also has a through hole 34. The through hole 34 penetrates the outer casing 3, connecting the interior and exterior of the outer casing 3.

[0057] Thus, as Figure 7 As shown, the top of the second outer skin 53 enters the interior of the outer shell 3 from the outside of the outer shell 3 through the through hole 34 and is fixed inside the outer shell. For example, it is fixed inside the outer shell 3 by being integrally formed with an adhesive, or by being fixed inside the outer shell 3 by the second fixing member 62 to the substrate 4.

[0058] The top of the second outer skin 53 emerges from the inside of the outer shell 3 through the through hole 34 and is fixed to the outer diameter deformation part 33.

[0059] Therefore, the outer skin 53 can be fixed both on the outside (outer diameter deformation part 33) and inside the outer shell 3, which greatly improves the reliability of the fixation.

[0060] Furthermore, the first fixing member 61 can be located inside the housing 3. In this way, it is possible to more reliably prevent external forces from pulling on the first outer sheath 52 and prevent the first outer sheath 52 from being peeled off from the inner core 51 of the cable.

[0061] In this case, the second outer skin 53 can be directly fixed to the substrate 4 or the inside of the outer shell 3, or it can be fixed to the outer surface of the outer shell 3 by returning from the inside of the outer shell 3 to the outside of the outer shell 3 via the cable channel 32.

[0062] Furthermore, the first fixing member 61 is part of the outer shell 3. The first fixing member 61 is formed by the deformation of the outer shell 3 under external force, which can reliably prevent the external force from pulling the first outer sheath 52 and prevent the first outer sheath 52 from being peeled off from the inner core 51 of the cable.

[0063] Furthermore, the fixation of the second outer skin 53 involved in this embodiment can be used simultaneously, in combination of several methods, or individually. For example, a portion of the second outer skin 53, which is divided into multiple segments, can be fixed to the substrate 4 by the first fixing member 61, a portion can be integrated with the adhesive by an adhesive, and a portion can be fixed to the outer surface of the outer shell 3, etc.

[0064] On the other hand, this embodiment also relates to an endoscope having any of the above-described imaging devices. Please refer to... Figure 8 The endoscope 101 includes a camera 1 capable of being inserted into a subject such as a human body and optically imaging a designated observation site within the subject. Furthermore, the subject inserted into the endoscope 101 is not limited to a human body; it can also be other living organisms, or artificial objects such as machinery or buildings.

[0065] The endoscope 101 mainly consists of an insertion section 102 that is inserted into the body of the patient, an operating section 103 located at the base of the insertion section 102, and the insertion section 102 is configured to continuously provide a front end portion 105 disposed at the front end, a flexible bending portion 104 disposed at the base of the front end portion 105, and a flexible tube portion disposed at the base of the bending portion 105 and connected to the front end of the operating section 103. The imaging element output signal from the imaging device 1 generates an image signal and outputs it to the image display unit 121.

[0066] Please see Figure 9The curved section 104 contains a plurality of segmented rings forming a curved serpentine structure. A connecting ring 106 for connecting to the curved serpentine structure is provided in the front end 105. The connecting ring 106 is fitted around the outer periphery of the front end side of the curved serpentine structure, and is located at the front end side of the first fixing member 61, meaning the connecting ring 106 is closer to the front end 105 than the first fixing member 61. The rear end of the connecting ring 106 is at least partially fitted onto the front end of the first fixing member 61, forming a certain overlap area in the axial direction. This overlap helps provide a stable assembly connection and provides axial restraint. Simultaneously, the inner diameter of the connecting ring 106 is less than or equal to the outer diameter of the first fixing member 61, ensuring that the first fixing member 61 is radially restricted, preventing radial loosening, and improving assembly accuracy and stability. This design ensures stability in connection with the connecting ring 106 and the end seat while also accommodating the flexibility of the curved serpentine structure of the insertion section.
