Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an endoscope. Background Technology

[0002] An endoscope is a medical device used to directly observe the internal cavities of human organs. Taking a laryngoscope as an example, during use, the laryngoscope needs to be partially inserted into the throat, making direct contact with human tissue. Through a camera module, it clearly reflects the internal condition of the throat, therefore it needs to meet high waterproof requirements.

[0003] Furthermore, since endoscopes such as laryngoscopes typically come into direct contact with human tissue, they often require immersion and disinfection, which places even higher demands on their waterproofing. Endoscopic devices like laryngoscopes often have various connecting structures to allow for bending during operation, and these structures can obstruct the view and compromise the waterproofing of the endoscope. Summary of the Invention

[0004] In view of this, the present invention provides an endoscope to solve the problem in the related art where the joint between the first pivot and the handle of the endoscope is prone to water leakage, which reduces the waterproof performance of the endoscope and makes it unable to meet the requirements of overall sealing and immersion waterproofing.

[0005] This invention provides an endoscope, comprising:

[0006] The housing includes a first housing and a second housing, which are connected. The housing has a pivot hole, and the first housing has a sealing ring. The sealing ring is coaxially arranged with the pivot hole, and the outer periphery of the sealing ring is sealed to the inner wall of the housing.

[0007] The first rotating shaft has its first end set inside the housing, and its second end passing through the sealing ring and the rotating shaft hole in sequence.

[0008] The first sealing ring is fitted on the outer circumference of the first rotating shaft and is disposed between the inner wall of the rotating shaft hole and the sealing ring.

[0009] The second rotating shaft is detachably connected to the second end of the first rotating shaft, and an angle is formed between the extending directions of the first and second rotating shafts.

[0010] Beneficial effects:

[0011] In the endoscope of the present invention, the first rotating shaft and the second rotating shaft are separate structures. Therefore, the diameter of the side of the first rotating shaft used to connect with the second rotating shaft is smaller, allowing the first rotating shaft to pass out from the first housing. Since the first rotating shaft passes out from the housing, during the assembly process, only the smaller second end of the first rotating shaft needs to pass through the sealing ring and the rotating shaft hole, while the larger second end does not need to pass through the sealing ring. This allows the sealing ring to be set as an integral structure and transitionally fitted with the first rotating shaft. The sealing ring fits tightly with the first sealing ring, thereby improving the sealing between the housing and the first rotating shaft, and thus improving the waterproof performance of the endoscope to ensure that the endoscope can meet the overall sealing immersion requirements.

[0012] In one optional embodiment, the second rotating shaft is provided with a limiting ring groove, and the endoscope also includes a second sealing ring sleeved outside the first rotating shaft. The housing is provided with a sealing ring wall, which is inserted into the limiting ring groove and abuts against the second sealing ring. The inner circumference of the sealing ring wall forms a rotating shaft hole.

[0013] Beneficial effects: The limiting ring groove can accommodate and limit the second sealing ring. The sealing ring wall extends into the limiting ring groove, which not only limits the second sealing ring but also seals the gap between the first and second rotating shafts through abutment. Therefore, the sealing ring wall and the second sealing ring cooperate to provide a double seal between the first and second rotating shafts, thereby reducing the risk of water ingress at the joint between the first and second rotating shafts and improving the waterproof effect of the endoscope.

[0014] In one optional embodiment, the housing includes a first housing and a rotating member, the first housing including a first shell and a second shell, the rotating member being connected to a second rotating shaft, and the endoscope further including:

[0015] A rotating component connected to a second rotating shaft;

[0016] A first wiring cavity is formed inside a first rotating shaft and extends along the length of the first rotating shaft;

[0017] The second wiring cavity is formed inside the second rotating shaft and is connected to the first wiring cavity. The second wiring cavity extends along the length of the second rotating shaft. A wire-passing hole is provided at the connection between the rotating part and the second rotating shaft. The wires in the first housing pass through the first wiring cavity, the second wiring cavity and the wire-passing hole in sequence and extend into the rotating part.

[0018] Beneficial effects:

[0019] During the assembly process of the endoscope of this application, the operator only needs to first assemble the first rotating shaft onto the first housing, then pass the wires in the first housing through the first wiring cavity and the second wiring cavity in sequence, then connect the second rotating shaft to the first rotating shaft, and finally pass the wires through the wire hole into the rotating part to easily pass the wires from the first rotating shaft into the second rotating shaft. The wiring process is simple and convenient, which helps to improve the preparation efficiency of the endoscope of this application.

[0020] In one alternative embodiment, the second end of the first rotating shaft is disposed within the second rotating shaft;

[0021] The endoscope also includes a limiting pin that passes through the end of the second rotating shaft and is inserted into the first rotating shaft. In an optional embodiment, the endoscope further includes a rotating member connected to the second rotating shaft, the rotating member comprising:

[0022] The mounting base is connected to one side of the rotating part, and the second rotating shaft passes through the mounting base and is rotatably connected to the mounting base.

[0023] Beneficial effects:

[0024] The second rotating shaft of the endoscope in this embodiment is rotatably connected to one side of the rotating member, thereby minimizing the area of ​​the opening on the rotating member and reducing the risk of water ingress at the joint between the rotating member and the second rotating shaft, which helps to improve the waterproof performance of the endoscope.

[0025] In one alternative embodiment, the rotating member further includes:

[0026] A sealing sleeve, fitted over the second rotating shaft and connected to one side of the rotating component, wherein a third sealing ring is provided between the sealing sleeve and the second rotating shaft; and / or,

[0027] A sealing groove is provided on one side of the rotating part, and the mounting seat is set in the sealing groove.

[0028] Beneficial effects:

[0029] The sealing sleeve can be sealed to the second rotating shaft via the third sealing ring, and at the same time, the sealing sleeve itself is sealed to one side of the rotating component. Therefore, the sealing sleeve forms a sealed cavity between the second rotating shaft and the wiring hole, thereby reliably waterproofing the wires extending from the second wiring cavity.

[0030] In one optional embodiment, the rotating component includes a second housing and a cover, the cover covering the opening of the second housing; one of the second housing and the cover has a first adhesive groove, and the other of the second housing and the cover has a first sealing protrusion; a sealing adhesive layer is provided between the first adhesive groove and the first sealing protrusion; and / or,

[0031] One of the second housing and the cover is provided with a first hook, and the other of the second housing and the cover is provided with a first slot, and the first hook can engage with the first slot.

[0032] Beneficial effects:

[0033] A slit is formed between the first sealing protrusion and the first dispensing groove, reducing the risk of water passing through between them. In addition, the first dispensing groove ensures that the dispensing material can flow smoothly, avoiding blockage and accumulation, ensuring the accuracy and uniformity of dispensing, and preventing leakage and overflow of adhesive, which helps to improve the sealing quality between the second housing and the cover.

[0034] In one optional embodiment, one of the first shell and the second shell is provided with a second adhesive groove, and the other of the first shell and the second shell is provided with a second sealing protrusion, the second sealing protrusion cooperating with the second adhesive groove, and a sealing adhesive layer being provided between the second adhesive groove and the second sealing protrusion; and / or,

[0035] One of the first shell and the second shell is provided with a second hook, and the other of the first shell and the second shell is provided with a second slot, the second hook being used to engage with the second slot; and / or,

[0036] The endoscope also includes a handle holder and a battery cover. The handle holder is disposed within the housing, and the battery cover is disposed on the handle holder. A space is provided between the handle holder and the battery cover to accommodate a battery. One of the handle holder and the battery cover has a third adhesive groove, and the other of the handle holder and the battery cover has a third positioning protrusion that mates with the third adhesive groove; and / or,

[0037] The endoscope also includes a pivot mounting ring, which is connected within the housing and located on the side of the sealing ring away from the pivot hole. An anti-disengagement flange is provided on the outer periphery of the first pivot, allowing the first pivot to pass through the inner ring of the pivot mounting ring and causing the anti-disengagement flange to abut against the pivot mounting ring; and / or,

[0038] The endoscope also includes a damping adjustment component connected to the first end of the first rotating shaft to adjust the rotational damping of the first rotating shaft. The area of ​​the damping adjustment component facing the sealing ring is larger than the inner ring area of ​​the sealing ring.

[0039] Beneficial effects:

[0040] The second sealing protrusion forms a slit with the second dispensing groove, reducing the risk of water passing between the second dispensing groove and the second sealing protrusion. In addition, the second dispensing groove is used to ensure that the dispensing material can flow smoothly, avoid blockage and accumulation, ensure the accuracy and uniformity of dispensing, avoid glue leakage and overflow, and help improve the sealing quality between the first shell and the second shell.

[0041] In the assembly process of the endoscope in this embodiment, the operator only needs to first connect the rotating shaft mounting ring inside the housing, and then pass the first rotating shaft through the rotating shaft mounting ring, the sealing ring and the rotating shaft hole in sequence, and make the anti-detachment flange abut against the end of the rotating shaft mounting ring away from the sealing ring, so as to complete the assembly of the first rotating shaft and prevent the first rotating shaft from coming off.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0070] According to an embodiment of the present invention, an endoscope is provided, comprising a housing, a first rotating shaft 2, a first sealing ring 3, a second rotating shaft 4, and a rotating component 5. The housing includes a first shell 101 and a second shell 102, which are connected. A rotating shaft hole 103 is provided on the housing. A sealing ring 1011 is provided on the first shell 101 near the rotating shaft hole 103, coaxially arranged with the rotating shaft hole 103, and its outer periphery is sealed to the inner wall of the housing. A first end of the first rotating shaft 2 is disposed within the housing, and a second end passes sequentially through the sealing ring 1011 and the rotating shaft hole 103. The first sealing ring 3 is sleeved on the outer periphery of the first rotating shaft 2 and disposed between the inner wall of the rotating shaft hole 103 and the sealing ring 1011. The second rotating shaft 4 is detachably connected to the second end of the first rotating shaft 2, and an angle is formed between the extending directions of the first rotating shaft 2 and the second rotating shaft 4.

[0071] In the endoscope of this invention, such as Figure 1 and Figure 2 As shown, the first rotating shaft 2 and the second rotating shaft 4 are separate structures. Therefore, the diameter of the side of the first rotating shaft 2 used to connect with the second rotating shaft 4 is smaller, allowing the first rotating shaft 2 to pass through the housing from the inside out. Since the first rotating shaft 2 passes through the housing from the inside out, during assembly, only the smaller second end of the first rotating shaft 2 needs to pass through the sealing ring 1011 and the shaft hole 103. The larger second end does not need to pass through the sealing ring 1011, allowing the sealing ring 1011 to be set as an integral structure (see...). Figure 3 It is fitted with the first rotating shaft 2 and the sealing ring 1011 is tightly fitted with the first sealing ring 3, thereby improving the sealing between the housing and the first rotating shaft 2, and thus improving the waterproof performance of the endoscope to ensure that the endoscope meets the overall sealing and immersion requirements.

[0072] It should be noted that the type of endoscope is not limited in this application embodiment. For example, the endoscope may be a laryngoscope, and the housing includes a first housing 1 and a rotating member 5. The rotating member 5 may be a screen, and the first housing 1 may be a handle housing.

[0073] The first shell 101 may be fixedly connected to the second shell 102, or it may be detachably connected to the second shell 102. The detachable connection is preferably, but not limited to, a riveting, snap-fit, or bolt connection.

[0074] The phrase "the second rotating shaft 2 is installed in conjunction with the first rotating shaft 2" means that the second rotating shaft 2 and the first rotating shaft 2 are separate structures, and the second rotating shaft 4 is connected to the first rotating shaft 2. Specifically, the first rotating shaft 2 and the second rotating shaft 4 can be either fixedly connected or detachably connected.

[0075] The rotating shaft mounting ring 7 is connected inside the housing and is located on the side of the sealing ring 1011 away from the rotating shaft hole 103. The outer periphery of the first rotating shaft 2 is provided with an anti-detachment flange 202. The first rotating shaft 2 can pass through the inner ring of the rotating shaft mounting ring 7 and make the anti-detachment flange 202 abut against the rotating shaft mounting ring 7.

[0076] During the assembly process of the endoscope in this embodiment of the application, such as Figure 4 As shown, the shaft mounting ring 7 is connected inside the housing. Then, the first shaft 2 passes through the shaft mounting ring 7, the sealing ring 1011 and the shaft hole 103 in sequence, and the anti-detachment flange 202 abuts against the end of the shaft mounting ring 7 away from the sealing ring 1011, thereby preventing the first shaft 2 from coming off.

[0077] In one embodiment, the shaft mounting ring 7 may be detachably connected to the housing, for example, by riveting, snap-fitting, or bolting. In one embodiment, the inner ring of the shaft mounting ring 7 is further provided with an annular groove 701, and an annular flange is located on the side of the shaft mounting ring 7 away from the sealing ring 1011. A sealing ring is provided between the annular groove 701 and the annular flange. The sealing ring is used to seal the gap between the first shaft 2 and the shaft mounting ring 7, thereby preventing water leakage between the first shaft 2 and the shaft mounting ring 7.

[0078] In one embodiment, the endoscope further includes a damping adjustment member 6 connected to the first end of the first rotating shaft 2 for adjusting the rotational damping of the first rotating shaft 2. The area of ​​the damping adjustment member 6 facing the sealing ring 1011 is larger than the area of ​​the inner ring of the sealing ring 1011.

[0079] Since the first rotating shaft 2 and the second rotating shaft 4 are separate structures in this application, the first rotating shaft 2 can pass through the rotating shaft hole 103 from the inside of the housing, allowing the inner ring of the sealing ring 1011 to be configured to transition fit with the first rotating shaft 2 and to cooperate with the first sealing ring 3, so as to implement a reliable connection at the joint between the first rotating shaft 2 and the housing.

[0080] In one embodiment, the damping adjustment member 6 includes a washer 601, an elastic element 602, and a nut 603 sequentially sleeved on the first rotating shaft 2 in a direction away from the sealing ring 1011. The nut 603 is threadedly connected to the first rotating shaft 2, and the operator can adjust the rotational damping of the first rotating shaft 2 by rotating the nut 603, as is well known to those skilled in the art, and therefore will not be described in detail here.

[0081] In one embodiment, such as Figure 6 As shown, the endoscope also includes a first wiring cavity 201 and a second wiring cavity 401. The first wiring cavity 201 is formed within the first rotating shaft 2 and extends along the length of the first rotating shaft 2. The second wiring cavity 401 is formed within the second rotating shaft 4 and communicates with the first wiring cavity 201. The second wiring cavity 401 extends along the length of the second rotating shaft 4. A wire-passing hole 501 is provided at the connection between the rotating component 5 and the second rotating shaft 4. Wires inside the first housing 1 pass through the first wiring cavity 201, the second wiring cavity 401, and the wire-passing hole 501 sequentially and extend into the rotating component 5.

[0082] During the assembly process of the endoscope of this application, the operator only needs to first assemble the first rotating shaft 2 onto the first housing 1, then pass the wires in the first housing 1 through the first wiring cavity 201 and the second wiring cavity 401 in sequence, then connect the second rotating shaft 4 to the first rotating shaft 2, and finally pass the wires through the wire hole 501 into the rotating part 5 to easily pass the wires from the first rotating shaft 2 into the second rotating shaft 4. The wiring process is simple and convenient, which helps to improve the preparation efficiency of the endoscope of this application.

[0083] In one embodiment, the second end of the first rotating shaft 2 is disposed within the second rotating shaft 4; the endoscope further includes a limiting pin 8, which passes through the end of the second rotating shaft 4 and connects to the first rotating shaft 2. The limiting pin 8 is used to reliably connect the first rotating shaft 2 and the second rotating shaft 4 without hindering the rotation of the second rotating shaft 4 relative to the rotating member 5.

[0084] Understandably, the connection method between the first rotating shaft 2 and the second rotating shaft 4 can be selected as plug-in riveting, snap-fit ​​or bolt connection.

[0085] In one embodiment, the second rotating shaft 4 is provided with a limiting ring groove 402, and the endoscope also includes a second sealing ring 9 sleeved outside the first rotating shaft 2. The housing is provided with a sealing ring wall 104, which is disposed in the limiting ring groove 402 and abuts against the second sealing ring 9. The inner circumference of the sealing ring wall 104 forms a rotating shaft hole 103.

[0086] The limiting ring groove 402 is used to accommodate and limit the second sealing ring 9. The sealing ring wall 104 extends into the limiting ring groove 402, which not only limits the second sealing ring 9, but also seals the gap between the first rotating shaft 2 and the second rotating shaft 4 by abutting. Therefore, the sealing ring wall 104 and the second sealing ring cooperate to provide a double seal between the first rotating shaft 2 and the second rotating shaft 4, thereby reducing the risk of water ingress at the joint of the first rotating shaft 2 and the second rotating shaft 4 and improving the waterproof effect of the endoscope.

[0087] In one embodiment, such as Figure 7 As shown, the rotating component 5 includes a mounting base 502. The mounting base 502 is connected to one side of the rotating component 5. The second rotating shaft 4 passes through the mounting base 502 and is rotatably connected to the mounting base 502.

[0088] The second rotating shaft 4 of the endoscope in this embodiment is rotatably connected to one side of the rotating member 5, which minimizes the area of ​​the opening on the rotating member 5, thereby reducing the risk of water entering at the joint between the rotating member 5 and the second rotating shaft 4 and helping to improve the waterproof performance of the endoscope.

[0089] It should be noted that the shape of the rotating member 5 is not limited in this embodiment of the application. For example, such as Figure 5 As shown, the rotating component 5 is a plate-shaped structure.

[0090] In one embodiment, such as Figure 5 As shown, the rotating component 5 also includes a sealing sleeve 503. The sealing sleeve 503 is sleeved outside the second rotating shaft 4 and connected to one side of the rotating component 5. A second sealing ring 9 is provided between the sealing sleeve 503 and the second rotating shaft 4.

[0091] The sealing sleeve 503 is sealed to the second rotating shaft 4 via the third sealing ring 10, and at the same time, the sealing sleeve 503 itself is sealed to one side plate of the rotating component 5. Therefore, the sealing sleeve 503 forms a sealed cavity between the second rotating shaft 4 and the wiring hole, thereby reliably waterproofing the wires extending from the second wiring cavity 401.

[0092] In one embodiment, a sealing groove 504 is provided on one side of the rotating member 5. The mounting base 502 is disposed within the sealing groove 504. The sealing groove 504 not only makes the endoscope structure more compact, but also forms a slit between the second rotating shaft 4 and the rotating member 5, thereby further reducing the risk of water ingress between the second rotating shaft 4 and the rotating member 5.

[0093] The rotating component 5 includes a second housing 505 and a cover 506. The cover 506 covers the opening of the second housing 505. One of the second housing 505 and the cover 506 is provided with a first adhesive groove 507, and the other of the two housings is provided with a first sealing protrusion 508. The first sealing protrusion 508 cooperates with the first adhesive groove 507. A sealing adhesive layer is provided between the first adhesive groove 507 and the first sealing protrusion 508.

[0094] A slit is formed between the first sealing protrusion 508 and the first dispensing groove 507, reducing the risk of water passing between them. In addition, the first dispensing groove 507 ensures the smooth flow of dispensing material, avoids clogging and accumulation, guarantees the accuracy and uniformity of dispensing, and prevents leakage and overflow of adhesive, thus helping to improve the sealing quality between the second housing 505 and the cover 506.

[0095] In one embodiment, a first hook 510 is provided on one of the second housing 505 and the cover 506, and a first slot 511 is provided on the other of the second housing 505 and the cover 506. The first hook 510 is used to engage with the first slot 511.

[0096] As an alternative implementation, the detachable connection between the second housing 505 and the cover 506 can also be selected as a plug-in connection, riveting connection, or bolt connection.

[0097] Specifically, the first adhesive groove 507 can be configured to surround the opening of the cover 506, and the first sealing protrusion 508 cooperates with the first adhesive groove 507 to seal the entire opening of the second housing 505.

[0098] In one embodiment, a second adhesive groove 105 is provided on one of the first shell 101 and the second shell 102, and a second sealing protrusion 106 is provided on the other of the first shell 101 and the second shell 102, and a sealing adhesive layer is provided between the second adhesive groove 105 and the second sealing protrusion 106.

[0099] A slit is formed between the second dispensing groove 105 and the second sealing protrusion 106, reducing the risk of water passing between the second dispensing groove 105 and the second sealing protrusion 106. In addition, the second dispensing groove 105 is used to ensure the smooth flow of dispensing material, avoid blockage and accumulation, ensure the accuracy and uniformity of dispensing, avoid glue leakage and overflow, and help improve the sealing quality between the first shell 101 and the second shell 102.

[0100] Specifically, in one embodiment, the second adhesive groove 105 is provided along the edge of the first shell 101, and the second sealing protrusion 106 is provided along the edge of the second shell 102.

[0101] Specifically, the connection between the first shell 101 and the second shell 102 can be a detachable connection.

[0102] In one embodiment, a second hook 107 is provided on one of the first shell 101 and the second shell 102, and a second slot 108 is provided on the other of the first shell 101 and the second shell 102, and the second hook 107 and the second slot 108 are engaged.

[0103] As an alternative implementation, the first shell 101 and the second shell 102 may also be riveted or threaded.

[0104] In one embodiment, such as Figure 8 As shown, the endoscope also includes a handle support 11 and a battery cover 12. The handle support 11 is disposed inside the housing, and the battery cover 12 is disposed on the handle support 11. A battery 13 is accommodated between the handle support 11 and the battery cover 12. One of the handle support 11 and the battery cover 12 is provided with a third adhesive groove 111, and the other of the handle support 11 and the battery cover 12 is provided with a third positioning protrusion. The third positioning protrusion cooperates with the third adhesive groove 111.

[0105] A slit is formed between the third adhesive groove 111 and the third sealing protrusion 121, reducing the risk of water passing between them. In addition, the third adhesive groove 111 ensures the smooth flow of adhesive material, avoids clogging and accumulation, ensures the accuracy and uniformity of adhesive dispensing, and prevents adhesive leakage and overflow, thus helping to improve the sealing quality between the handle bracket 11 and the battery cover 12.

[0106] Specifically, the third adhesive groove 111 can be arranged around the battery 13, and the third positioning protrusion cooperates with the third adhesive groove 111. When the battery cover 12 is placed on the handle bracket 11, the third positioning protrusion is located in the third adhesive groove 111.

[0107] Specifically, the connection between the handle bracket 11 and the battery cover 12 can be a detachable connection, preferably but not limited to snap-fit, riveting or bolt connection.

[0108] In one embodiment, such as Figure 3 As shown, the endoscope also includes an insertion end 14 and a camera module 15.
