Description

Technical Field

[0001] The present invention relates to the field of endoscopes, and in particular to an insertion portion membrane assembly and an endoscope assembly. Background Art

[0002] Endoscopes are one of the most widely used diagnostic and therapeutic tools in modern medicine, especially in gastrointestinal endoscopy, bronchoscopy, cystoscopy, etc., playing an irreplaceable role. However, since endoscopes are in direct contact with the digestive tract, respiratory tract and other parts of the patient's body, there is a high risk of infection. Therefore, they must be strictly cleaned and disinfected after each use to ensure patient safety. This disinfection process usually includes multiple steps such as mechanical cleaning, chemical disinfection, drying and sterilization. The cost of the equipment and consumables required is very high and the cycle is long. Therefore, for medical institutions, the cost of disinfection and reprocessing of endoscopes has become a cost burden that cannot be ignored, especially when the number of patients is large. This problem is particularly prominent.

[0003] In order to reduce the cost of disinfection and improve the efficiency of use, disposable endoscopes came into being. Disposable endoscopes solve the problems of high cost, complicated disinfection process and difficult infection control caused by repeated disinfection by reducing the disinfection steps of traditional endoscopes. In some departments that are particularly sensitive to infection risks, such as emergency and intensive care, the rapid use and safety of disposable endoscopes are particularly important. However, although disposable endoscopes have significant advantages in specific situations, their production costs are still high, especially the manufacturing of core components such as endoscope lenses and sensors requires sophisticated technical processes. In addition, disposable endoscopes are discarded after use, generating a large amount of medical waste. Since medical waste needs to undergo special treatment procedures to avoid its negative impact on the environment and public health, new environmental burdens and treatment costs are generated, which further increases the overall expenditure of hospitals.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0031] The inventive concept of the present application is described here:

[0032] Endoscopes are one of the most widely used diagnostic and therapeutic tools in modern medicine, especially in gastrointestinal endoscopy, bronchoscopy, cystoscopy, etc., playing an irreplaceable role. However, since endoscopes are in direct contact with the digestive tract, respiratory tract and other parts of the patient's body, there is a high risk of infection. Therefore, they must be strictly cleaned and disinfected after each use to ensure patient safety. This disinfection process usually includes multiple steps such as mechanical cleaning, chemical disinfection, drying and sterilization. The cost of the equipment and consumables required is very high and the cycle is long. Therefore, for medical institutions, the cost of disinfection and reprocessing of endoscopes has become a cost burden that cannot be ignored, especially when the number of patients is large. This problem is particularly prominent.

[0033] In order to reduce the cost of disinfection and improve the efficiency of use, disposable endoscopes came into being. Disposable endoscopes solve the problems of high cost, complicated disinfection process and difficult infection control caused by repeated disinfection by reducing the disinfection steps of traditional endoscopes. In some departments that are particularly sensitive to infection risks, such as emergency and intensive care, the rapid use and safety of disposable endoscopes are particularly important. However, although disposable endoscopes have significant advantages in specific situations, their production costs are still high, especially the manufacturing of core components such as endoscope lenses and sensors requires sophisticated technical processes. In addition, disposable endoscopes are discarded after use, generating a large amount of medical waste. Since medical waste needs to undergo special treatment procedures to avoid its negative impact on the environment and public health, new environmental burdens and treatment costs are generated, which further increases the overall expenditure of hospitals.

[0034] Based on this, the inventor provides an insertion part membrane assembly and an endoscope assembly. The insertion part membrane assembly is a disposable product. The insertion part membrane assembly can be sleeved on the outer surface of the insertion part and is used to prevent the insertion part from contacting the external environment. In this way, the operator will not contaminate the insertion part during the use of the endoscope. When the operator has finished use, the membrane on the outside of the insertion part can be directly removed and replaced with a new membrane for reuse. This process does not require disinfection of the endoscope, reduces the use cost of the endoscope, and shortens the vacuum period when the endoscope is in a disinfected state and cannot be used.

[0035] The following is combined with Figures 1 to 8 , an insertion membrane assembly 10 and an endoscope assembly 1 provided in the present application are described in detail through specific embodiments and their application scenarios.

[0036] Please also see Figure 1 and Figure 2An embodiment of the present application provides an insertion membrane assembly 10, which can be used for an endoscope 90. The endoscope 90 can include an insertion portion 80. The insertion membrane assembly 10 can be used to be sleeved on the outer surface of the insertion portion 80 to prevent the insertion portion 80 from being contaminated by the external environment.

[0037] Please also see Figure 2-Figure 4 , the insertion membrane assembly 10 may include: a front end seat 110, a membrane body 20 and an instrument tube 30. Both the membrane body 20 and the instrument tube 30 may be connected to the front end seat 110. In the present embodiment, the front end seat 110 may be used as a mounting base. The present application embodiment does not limit the specific material of the front end seat 110. For example, in one embodiment, the front end seat 110 may be made of a hard material, which can facilitate the connection of the membrane body 20 and the instrument tube 30 to the front end seat 110. It should be noted that the present application embodiment does not limit the connection method between the membrane body 20 and the front end seat 110, and does not limit the connection method of the instrument with respect to the front end seat 110. As long as the connection is sealed, it can be sufficient. For example, in one embodiment, welding can be used for connection. The specific setting can be made according to the actual situation.

[0038] Further, the distal end of the front seat 110 can be transparently set, so that the endoscope 90 can observe the external environment, and the front seat 110 has a sealing area 111 and an open area 112 in the radial direction. The sealing area 111 can be used to accommodate the insertion part 80 to prevent the insertion part 80 from being contaminated by the external environment. The open area 112 can be used to accommodate the instrument tube 30, so that the medical device can be extended from the instrument tube 30, thereby facilitating the operator to perform surgery on the patient. It is understandable that the instrument tube 30 and the medical device can adopt a disposable structure. The production cost of these components is low. The disposable setting can help save time and save the additional costs generated during the disinfection process. It is understandable that in some other embodiments, the instrument tube 30 and the medical device can also adopt a reused structure. Similarly, due to the low production cost of the instrument tube 30 and the medical device, a large number of instrument tubes 30 and medical devices can be prepared. After use, they can be disinfected using a low-cost, long-term disinfection method to achieve the purpose of reuse, which can also reduce the use cost of the endoscope 90.

[0039] Further, in some embodiments, the front end seat 110 may be provided with a stopper 113 protruding into the installation channel 210, and the stopper 113 may be used to assist in clamping the insertion portion 80, so that the insertion portion 80 is more closely connected to the membrane body 20 after the membrane is applied, reducing the probability of the membrane body 20 falling off from the insertion portion 80, which is conducive to ensuring that the insertion portion 80 is not contaminated by the external environment. It is understandable that the embodiment of the present application does not limit the specific position and number of the stopper 113, and it can be adaptively set according to the specific structure of the front end seat 110. For example, in this embodiment, a part of the area of ​​the front end seat 110 can extend in the second direction 50, and the stopper 113 can be set on the inner wall of the aforementioned area extending in the second direction 50.

[0040] The membrane body 20 may be formed with a mounting channel 210, the membrane body 20 may be sealed and connected to the front end seat 110, and extend in the first direction 40. Specifically, in the present embodiment, the membrane body 20 may be set to a cylindrical structure, the membrane body 20 may have a first surface and a second surface opposite to each other, wherein the first surface may be an inner surface, the second surface may be an outer surface, and the first surface may be sealed and connected to the front end seat 110. When the user performs a film covering operation on the insertion part 80, the insertion part 80 may be aligned with the mounting channel 210, at which time the insertion part 80 contacts the first surface of the membrane body 20, and then the user may push the insertion part 80 to move in the first direction 40 to achieve reverse film covering, during which the first surface is fitted with the insertion part 80, and when the user completes the film covering, the first surface changes from the original inner surface to the outer surface.

[0041] Please also see Figure 5-Figure 7 In one embodiment, a support ring 220 may be provided at the distal end of the membrane body 20, and the size of the support ring 220 may be larger than the size of the membrane body 20. It is understood that the size here refers to the cross-sectional size along the axial direction of the membrane body 20, which can facilitate the use of the support ring 220 to more conveniently perform the membrane during the membrane covering process. It should be noted that the aforementioned distal end refers to the distal end of the membrane body 20 before it is sleeved on the insertion part 80. After the membrane body 20 is sleeved on the insertion part 80, the support ring 220 is located at the proximal end of the membrane body 20. It is understood that when the membrane body 20 is gradually sleeved toward the proximal end of the insertion part 80, the size of the proximal end of the insertion part 80 is usually slightly larger than the size of the front end of the insertion part 80, so the provision of the support ring 220 can make the portion of the membrane body 20 that fits the insertion part 80 more matched.

[0042] The instrument tube 30 can be sealed and connected to the open area 112, and extend along the second direction 50. The interior of the instrument tube 30 is through-set to form an instrument channel 310, and the instrument channel 310 can be used for medical instruments to pass through. In this embodiment, the second direction 50 is set opposite to the first direction 40. When the user performs the sheathing operation on the insertion part 80, the insertion part 80 and the instrument tube 30 can be moved simultaneously in the first direction 40 to achieve the sheathing process of the insertion part 80 and the instrument tube 30 at the same time. That is to say, in this embodiment, the instrument channel 310 is located inside the installation channel 210 and occupies a part of the area of ​​the installation channel 210. The remaining area of ​​the installation channel 210 can be used as an area for accommodating the insertion part 80.

[0043] Please continue reading Figure 2 In this embodiment, the proximal end of the instrument tube 30 may be provided with a functional device 910, which may be a negative pressure valve or an instrument plug, etc., and may be specifically provided according to the situation. For example, when the operator needs to use the endoscope 90 to suck out foreign matter in the patient's body, the functional device 910 may be provided as a negative pressure valve, and negative pressure may be applied thereto to suck out the foreign matter in the patient's body. It should be noted that in this embodiment, the functional device 910 may be detachably connected to the instrument tube 30, so that the operator can connect different functional devices 910 according to different situations.

[0044] Please continue reading Figure 5-Figure 7 In one embodiment, the insertion portion membrane assembly 10 may further include: an auxiliary assembly 60, which may be used to assist the user in straightening the insertion portion 80, thereby facilitating the insertion portion 80 to perform a membrane operation. The auxiliary assembly 60 is detachably disposed at the distal end of the instrument channel 310, and extends in the first direction 40 out of the area surrounded by the membrane body 20, so that the user can pull the auxiliary assembly 60.

[0045] In a specific embodiment, the auxiliary component 60 may include: a plug body 610 and a rope body 620, wherein the plug body 610 is detachably disposed at the distal end of the instrument channel 310, and the rope body 620 may be connected to the plug body 610 and extend along the first direction 40, and extend out of the area surrounded by the membrane body 20. It should be noted that the embodiment of the present application does not set a specific connection method between the rope body 620 and the plug body 610. For example, in an embodiment, the rope body 620 may be integrally formed with the plug body 610, which may improve the consistency between the rope body 620 and the plug body 610, thereby avoiding or reducing the possibility of tearing the rope body 620 and the plug body 610 apart.

[0046] Also, please read Figure 5-Figure 7In some embodiments, the insertion portion membrane assembly 10 may further include: a support assembly 70, which may be sleeved outside the front end seat 110. It is understandable that since the membrane body 20 is made of a soft elastic material and the insertion portion 80 is also made of a soft elastic material, the membrane may be sleeved slowly during the process of inserting the membrane body 20 into the insertion portion 80. Therefore, the support assembly 70 may be used to support the membrane body 20, thereby facilitating the membrane body 20 to be sleeved on the insertion portion 80.

[0047] The embodiments of the present application also do not limit the specific structure of the support assembly 70. For example, in some embodiments, the insertion assembly can be configured to have a funnel-like structure, that is, the support assembly 70 can have a first end 710 and a second end 720 relative to each other, wherein the size of the second end 720 is larger than the size of the first end 710, and the first end 710 is sleeved outside the front end seat 110. The aforementioned configuration can facilitate sleeveing ​​of the support assembly 70 on the front end seat 110.

[0048] In addition, in one embodiment, the support assembly 70 can be configured as a hollow cylindrical structure. After the insertion portion 80 completes the membrane, it is usually necessary to apply a layer of lubricating oil to the outer surface of the membrane body 20 so that the insertion portion 80 can move more smoothly in the patient's body. Therefore, the structure of the aforementioned support assembly 70 can facilitate the application of oil to the outside of the membrane body 20. Specifically, when the user needs to apply oil, the lubricating oil can be directly poured from the second end 720 into the support assembly 70. The user can complete the oiling operation of the membrane body 20 while removing the support assembly 70 from the insertion portion 80.

[0049] In one embodiment, the support assembly 70 may also have a limiting ring 730. The limiting ring 730 may be disposed between the first end 710 and the second end 720. The limiting ring 730 may be disposed so as to protrude away from the instrument channel 310. The limiting ring 730 may be used to limit the position of the membrane body 20 so that the membrane body 20 is in a taut state before contacting the insertion portion 80, thereby facilitating the membrane body 20 to better fit the outer surface of the insertion portion 80.

[0050] For further information, please also refer to Figure 7 and Figure 8 In one embodiment, a portion of the membrane body 20 may be wrinkled or folded, which can reduce the length of the membrane body 20 and facilitate the storage or transportation of the insertion membrane assembly 10. In a more specific embodiment, the wrinkled area or folded area of ​​the membrane body 20 is disposed close to the support ring 220.

[0051] The assembly process and working principle of the insertion membrane assembly 10 provided in the embodiment of the present application will be described below:

[0052] First, the membrane body 20 can be aligned with the sealing area 111, and the front end seat 110 is sealed and connected with the membrane body 20, at which time the membrane body 20 extends in the first direction 40, and then the instrument tube 30 is aligned with the open area 112, and then the instrument tube 30 is sealed and connected with the front end seat 110, at which time the instrument tube 30 extends in the second direction 50, and then the insertion part 80 is aligned with the installation channel 210. Then the front end seat 110 is fixed, and the insertion part 80 and the instrument tube 30 are pushed in the first direction 40 at the same time, so that the insertion part 80 and the instrument tube 30 can be sleeved inside the membrane body 20, so as to realize the sleeve operation of the insertion part membrane assembly 10 on the insertion part 80 and the instrument tube 30.

[0053] In summary, the insertion portion membrane assembly 10 provided in the embodiment of the present application is provided with a sealing area 111 and an open area 112 on the front end seat 110, and the membrane body 20 is sealedly connected to the front end seat 110, and the instrument tube 30 is sealedly connected to the open area 112. At this time, the instrument channel 310 formed in the instrument tube 30 is sealed relative to the installation channel 210 in the membrane body 20. In this embodiment, the membrane body 20 extends along the first direction 40, and the instrument tube 30 extends along the second direction 50. When it is necessary to cover the insertion portion 80, the insertion portion 80 can be directly docked with the installation channel 210 in the membrane body 20, and then the insertion portion 80 and the instrument tube 30 are simultaneously pushed in the first direction 40, and the inner surface of the membrane body 20 is wrapped around the outer surface of the insertion portion 80 and the instrument tube 30, so as to realize the covering operation of the insertion portion 80. After the insertion part membrane assembly 10 provided in the embodiment of the present application completes the sheathing operation on the insertion part 80 and the instrument tube 30, the insertion part 80 can be located in the sealing area 111, and the external environment cannot affect the insertion part 80, so that the insertion part 80 can be reused without disinfection, thereby solving the problem of high cost of disinfection of the endoscope 90 in the prior art and reducing the use cost of the endoscope 90.

[0054] Please refer again Figure 1 The embodiment of the present application also provides an endoscope assembly 1, which may include the insertion portion membrane assembly 10 and the endoscope 90 as described above, and the endoscope 90 may have an insertion portion 80, and the insertion portion 80 may be nested in the insertion portion membrane assembly 10. The endoscope assembly 1 provided in the embodiment of the present application is provided with the insertion portion membrane assembly 10 as described above, so it can also solve the problem of high cost of disinfection of the endoscope 90 in the prior art, and reduce the use cost of the endoscope 90.
