Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a disposable bronchoscope. Background Technology
[0002] An endoscope is an examination instrument that can directly enter the body's natural passages, providing doctors with ample diagnostic information for disease treatment. However, traditional endoscopes have a complex structure, making them difficult to thoroughly clean and sterilize. The use of the same endoscope among different patients can easily lead to cross-infection, causing serious harm to the infected person's health, and even death. Related studies show that endoscopes rank first in the list of medical device cross-infection risks, making the development of disposable endoscopes urgently needed.
[0003] However, existing disposable endoscopes have a relatively simple structure and lack any protective measures. When doctors make mistakes or are influenced by patients or others, the endoscope can easily be inserted or withdrawn excessively. This not only exacerbates the patient's unpleasant experience but can also threaten the patient's life in severe cases. In addition, most patients experience difficulty breathing during endoscopic procedures, and oxygen supply at this time can seriously affect the operation of medical staff, thereby affecting the accuracy of the examination results.
[0004] Therefore, it is necessary to provide a disposable bronchoscope to solve the above problems. Summary of the Invention
[0005] To achieve the above objectives, the present invention provides the following technical solution: a disposable bronchoscope, comprising:
[0006] The operating handle has a focusing ring and a control lever at its upper end, and an image connection line is provided at the upper end of the focusing ring and the control lever. The image connection line is externally connected to an endoscope processor.
[0007] The lower end of the operating handle is provided with a direction-transmitting light-transmitting illumination hose, and the front end of the direction-transmitting light-transmitting illumination hose is provided with an illumination and imaging probe.
[0008] A limiting device is fitted on the outside of the directional light transmission and illumination hose. A breathing mask is fixedly fitted at the lower end of the limiting device, and an insertion position guide component is fixedly fitted on the inner wall of the upper end of the breathing mask.
[0009] Furthermore, as a preferred embodiment, the breathing mask is provided with an auxiliary breathing tube on the left side, and an auxiliary breathing device or oxygen supply device is connected to the other side of the auxiliary breathing tube.
[0010] Furthermore, preferably, the limiting device includes:
[0011] The limiting tube is fixedly assembled on the upper end of the breathing mask. Three sets of elastic spacers are coaxially fixedly assembled on its inner side. The three sets of elastic spacers are coaxially fitted on the direction transmission light transmission and illumination hose. The elastic spacers and the direction transmission light transmission and illumination hose divide the limiting tube into a cooling zone, a warming zone, and a dehumidification zone.
[0012] Furthermore, as a preferred embodiment, the cooling zone, the reheating zone, and the dehumidification zone are respectively fixedly assembled with cooling components, reheating components, and dehumidification components on their pipe walls.
[0013] Furthermore, as a preferred embodiment, multiple sets of elastic limiting components are rotatably mounted on the inner wall of the cooling zone.
[0014] Furthermore, preferably, the elastic limiting component includes:
[0015] Two sets of shock-absorbing springs are arranged in a mirror image. One end of the spring is rotatably mounted on the inner wall of the cooling zone of the limiting tube, and the other end is rotatably mounted on a rotating shaft with a rotating wheel mounted on it. A one-way rotating bearing is provided between the rotating wheel and the shock-absorbing spring.
[0016] Furthermore, as a preferred embodiment, a rotation speed limiter is provided on the rotating shaft.
[0017] Furthermore, as a preferred embodiment, the telescopic rod inside the upper shock-absorbing spring is a hydraulic rod.
[0018] Furthermore, preferably, the insertion position guiding component includes:
[0019] A guide shell is fixedly mounted on the inner wall of the upper end of the respirator. A rotating ball is rotatably mounted inside the guide shell. The upper end of the rotating ball is rotatably mounted on the lower end of the limiting device, and a transmission gear is provided between the two. The transmission gear is coaxially fixed with the rotating ball. A micro motor is fixedly mounted on the outer wall of the lower end of the limiting device. A drive gear is coaxially fixedly mounted on the output shaft of the micro motor. The drive gear meshes with the transmission gear.
[0020] Furthermore, as a preferred embodiment, the rotating ball has an upper main channel and three sets of secondary channels on the lower side, and the lower side of the guide shell has an oral cavity inlet and two sets of nasal cavity inlets corresponding to the three sets of secondary channels.
[0021] Compared with the prior art, the present invention provides a disposable bronchoscope, which has the following beneficial effects:
[0022] 1. In this invention, a breathing mask is provided to assist the patient's breathing, preventing adverse reactions during surgery. When the patient's breathing is relatively good, an external oxygen supply device is connected to the auxiliary breathing tube to further ensure the patient's breathing. If the patient's breathing is poor, an external auxiliary breathing device is connected to the auxiliary breathing tube to enhance the patient's breathing and further ensure the patient's life safety. At the same time, an insertion position guide component is provided to effectively avoid poor vision caused by oxygen access and to guide the insertion of the light transmission and illumination tube. The patient can also freely choose between the oral cavity or one of the two nasal cavities according to their actual situation and personal preference, improving the patient's user experience.
[0023] 2. In this invention, a limiting device is provided, which includes a cooling zone, a reheating zone, and a dehumidification zone. The cooling zone is equipped with an elastic limiting component and a cooling component. The cooling component hardens the directional light transmission and illumination hose, facilitating the fixation of the limiting device and preventing it from being forcibly inserted into or pulled out of the patient's bronchus, thus threatening the patient's safety. The reheating component in the reheating zone can raise the temperature of the directional light transmission and illumination hose to the normal human body temperature, preventing it from irritating the patient's trachea. At the same time, it relieves the stiffness of the hose in the cooling zone, facilitating subsequent operations by medical personnel. The dehumidification component in the dehumidification zone prevents condensation from forming on the directional light transmission and illumination hose after cooling and reheating, which could harm the patient.

[0029] Please see Figures 1-4 The present invention provides a disposable bronchoscope, comprising:
[0030] The operating handle 1 has a focusing ring 2 and a control lever 3 at its upper end, and an image connection line 4 is provided at the upper end of the focusing ring 2 and the control lever 3. The image connection line 4 is externally connected to an endoscope processor.
[0031] The lower end of the operating handle 1 is provided with a direction-transmitting light-transmitting illumination hose 5, and the front end of the direction-transmitting light-transmitting illumination hose 5 is provided with an illumination and imaging probe.
[0032] The outer side of the light transmission and illumination hose 5 is fitted with a limiting device 6, and a breathing mask 8 is fixedly assembled at the lower end of the limiting device 6. An insertion position guide component 7 is fixedly assembled on the inner wall of the upper end of the breathing mask 8.
[0033] In a preferred embodiment, during use, the breathing mask 8 is placed over the patient's mouth and nose to assist breathing and prevent adverse reactions during surgery. A suitable insertion point is selected based on the patient's actual condition and personal preference, and the insertion position guide component 7 is adjusted to a suitable angle. The medical staff holds the operating handle 1 and guides the directional light transmission and illumination hose 5, equipped with an illumination and imaging probe, through the limiting device 6 and guided by the insertion position guide component 7, into the patient's bronchus for surgical procedures. If the medical staff accidentally shakes their hand or the patient experiences a violent movement such as sneezing, the limiting device 6 will lock the directional light transmission and illumination hose 5 to a certain extent, preventing it from violently entering or exiting and causing tracheal damage, further ensuring the patient's safety.
[0034] Furthermore, the breathing mask 8 is provided with an auxiliary breathing tube 9 on the left side, and an auxiliary breathing device or oxygen supply device is connected to the other side of the auxiliary breathing tube 9.
[0035] In a preferred embodiment, when the patient's breathing condition is relatively good, the auxiliary breathing tube 9 is connected to an external oxygen supply device to further ensure the patient's breathing condition. If the patient's breathing condition is poor, the auxiliary breathing tube 9 is connected to an external auxiliary breathing device to enhance the patient's breathing condition and further ensure the patient's life safety.
[0036] Furthermore, the limiting device 6 includes:
[0037] The limiting tube 61 is fixedly assembled on the upper end of the breathing mask 8. Three sets of elastic spacers 62 are coaxially fixedly assembled on its inner side. The three sets of elastic spacers 62 are coaxially fitted on the direction transmission light transmission and illumination hose 5. The elastic spacers 62 and the direction transmission light transmission and illumination hose 5 divide the limiting tube 61 into a cooling zone, a warming zone and a dehumidification zone.
[0038] In a preferred embodiment, the elastic spacer 62 is an elastic structure that can isolate the conduction of temperature to a certain extent. Its outer side is fixedly mounted on the inner wall of the limiting tube 61, and its inner side is provided with a through hole and is slidably connected to the direction-transmitting light-transmitting lighting hose 5. The through hole in the middle can elastically deform according to the size of the direction-transmitting light-transmitting lighting hose 5, thereby adapting to various sizes of direction-transmitting light-transmitting lighting hose 5 and improving the practicality of the device.
[0039] Furthermore, a refrigeration component 63, a reheating component 64, and a dehumidification component 65 are respectively fixedly assembled on the pipe walls of the refrigeration zone, the reheating zone, and the dehumidification zone;
[0040] In a preferred embodiment, the cooling component 63 can lower the temperature of the cooling zone, thereby hardening the directional light transmission and illumination hose 5 located in the cooling zone, facilitating the fixation of the limiting device 6 and preventing it from forcibly entering or being pulled out of the patient's bronchus, thus threatening the patient's safety. The warming component 64 can raise the temperature of the warming zone, raising the temperature of the directional light transmission and illumination hose 5 in the warming zone to the normal human body temperature, preventing it from irritating the patient's trachea, and simultaneously relieving its stiffness in the cooling zone, making it easier for medical staff to perform subsequent operations. The dehumidifying component 65 prevents condensation from forming on the directional light transmission and illumination hose 5 after cooling and warming, thus preventing harm to the patient.
[0041] Furthermore, multiple sets of elastic limiting components 66 are rotatably mounted on the inner wall of the cooling zone. The elastic limiting components 66 are used to limit the insertion state of the light transmission and illumination hose 5.
[0042] Furthermore, the elastic limiting component 66 includes:
[0043] Two sets of shock-absorbing springs 661 are mirror-arranged. One end of the spring is rotatably mounted on the inner wall of the cooling zone of the limiting tube 61, and the other end is rotatably mounted on a rotating shaft 664, on which a rotating wheel 662 is rotatably mounted. A one-way rotating bearing 663 is provided between the rotating wheel 662 and the shock-absorbing spring 661.
[0044] In a preferred embodiment, in the initial state, the shock-absorbing spring 661 is in a natural state, and the rotating wheels 662 of the multiple sets of elastic limiting components 66 are in contact with each other. At this time, the gap in the middle is small. When the directional light-transmitting illumination hose 5 is inserted, it becomes stiff under the action of the cooling component 63. As it is inserted, the rotating wheel 662 rotates downward with the directional light-transmitting illumination hose 5 and moves outward. The shock-absorbing spring 661 is compressed until the directional light-transmitting illumination hose 5 passes through the gap between the multiple rotating wheels 662. At the same time, the one-way rotating bearing 663 restricts the rotating wheel 662 from rotating upward, which greatly enhances the friction between it and the directional light-transmitting illumination hose 5, preventing the directional light-transmitting illumination hose 5 from being pulled out in case of an accident, which could cause irreversible damage to the patient.
[0045] Furthermore, a rotation speed limiter 665 is provided on the rotating shaft 664. By setting the rotation speed limiter 665, the insertion speed of the light-transmitting and illumination hose 5 can be further limited by limiting the rotation speed of the rotating wheel 662, preventing medical staff from inserting too quickly in tense or accidental situations, which could cause tracheal damage to the patient and further ensure the patient's safety.
[0046] Furthermore, the telescopic rod inside the shock-absorbing spring 661 on the upper side is a hydraulic rod 666;
[0047] In a preferred embodiment, the hydraulic rod 666 is not in operation in the initial state. Its front end is in a normal telescopic state, which facilitates the insertion of different sized directional light transmission and illumination hoses 5. Its rear end is in a hydraulic telescopic state. After the operation is completed, by controlling the hydraulic section of the hydraulic rod 666, the rotating wheel 662 can be moved outward and the shock-absorbing spring 661 can be compressed to release the restriction on the directional light transmission and illumination hose 5, so that it can be pulled out normally.
[0048] Furthermore, the insertion position guiding component 7 includes:
[0049] A guide shell 71 is fixedly mounted on the inner wall of the upper end of the respirator 8. A rotating ball 74 is rotatably mounted inside the guide shell 71. The upper end of the rotating ball 74 is rotatably mounted on the lower end of the limiting device 6, and a transmission gear 75 is provided between the two. The transmission gear 75 is coaxially fixed with the rotating ball 74. A micro motor 77 is fixedly mounted on the outer wall of the lower end of the limiting device 6. A drive gear 76 is coaxially fixedly mounted on the output shaft of the micro motor 77. The drive gear 76 meshes with the transmission gear 75.
[0050] Furthermore, the rotating ball 74 has an upper main channel and three sets of secondary channels on the lower side, and the guide shell 71 has an oral cavity inlet 72 corresponding to the three sets of secondary channels and two sets of nasal cavity inlets 73 on the lower side.
[0051] In a preferred embodiment, the insertion position guidance component 7 can effectively avoid poor vision caused by oxygen access, guide the insertion of the light transmission and illumination hose 5, and allow the patient to freely choose between the oral cavity or one of the two nasal cavities according to their actual situation and personal wishes, thereby improving the patient's user experience.
[0052] The specific implementation includes the following steps: When in use, the breathing mask 8 is placed over the patient's mouth and nose to assist the patient's breathing and prevent adverse reactions during the operation. According to the patient's actual situation and personal wishes, a suitable insertion point is selected, and the insertion position guide component 7 is adjusted to a suitable angle. The medical staff holds the operating handle 1 and inserts the directional light transmission and illumination hose 5, which is equipped with an illumination and imaging probe, into the bronchus of the patient through the mouth or nose under the guidance of the limiting device 6 and the insertion position guide component 7. If the medical staff accidentally shakes their hand or the patient sneezes or performs other violent actions, the limiting device 6 will lock the directional light transmission and illumination hose 5 to a certain extent to prevent it from violently entering or exiting and causing tracheal damage to the patient, thereby further ensuring the patient's life safety.
[0053] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
