DETAILED DESCRIPTION

[0044] 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.

[0045] 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.

[0046] 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".

[0047] The inventive concept of the present application is described here:

[0048] 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.

[0049] In the prior art, the outer surface of the insertion part of the endoscope is covered with a film to prevent the endoscope from being contaminated during the operation. After the operation, the film layer on the outer surface of the insertion part of the endoscope can be directly replaced and reused, which can reduce the cost of disinfection and reprocessing of the endoscope. However, due to the low structural rigidity of the insertion part of the endoscope, it is difficult for the user to quickly cover the insertion part of the endoscope. Specifically, wrinkles are likely to appear on the protective film during the process of bonding with the surface of the insertion part, which will reduce the surface flatness of the insertion part after the protective film is covered, which is not conducive to subsequent use. Therefore, it is necessary to eliminate the aforementioned wrinkles, which will greatly increase the covering time of the insertion part.

[0050] Based on this, the inventor provides an insertion portion membrane assembly and an endoscope assembly, wherein the insertion portion membrane assembly is configured so that the protective film is in a taut state before the sleeve is applied, so that the protective film can fit tightly with the insertion portion when in contact with the insertion portion, thereby eliminating wrinkles, thereby greatly improving the progress and efficiency of the sleeve application.

[0051] The following is combined with Figures 1 to 19 , an insertion membrane assembly 10 and an endoscope assembly 1 provided by the present application are described in detail through specific embodiments and their application scenarios. The present application embodiment provides an insertion membrane assembly 10, which can be used for an endoscope 20, and the endoscope 20 includes an insertion portion 210, and the insertion membrane assembly 10 can be used to apply a film to the insertion portion 210 of the endoscope 20.

[0052] Please also see Figure 1-Figure 2, the inserting part membrane assembly 10 may include: a sleeve mold 110, a protective film 120 and a glass slide 130. The sleeve mold 110 may serve as a carrier of the protective film 120. The protective film 120 may be sleeved on the sleeve mold 110, so as to facilitate the subsequent sleeve of the protective film 120 on the inserting part 210. The embodiment of the present application does not limit the specific structure of the sleeve mold 110. In one embodiment, the sleeve mold 110 may be set as a cylindrical structure, which can facilitate the sleeve of the protective film 120 on the sleeve mold 110. It should be noted that the two ends of the sleeve mold 110 may be set through, and the sleeve mold 110 has a through hole 1111 inside, which can facilitate the insertion part 210 to pass through the through hole 1111 of the sleeve mold 110 during the sleeve process to reduce the length of the sleeve mold 110.

[0053] Please also see Figure 1-Figure 5 In a specific embodiment, the film sleeve mold 110 may include a first barrel 111 and a second barrel 112, a through hole 1111 may be formed inside the first barrel 111, the second barrel 112 may be sleeved on the periphery of the first barrel 111, and an installation space 114 may be formed between the first barrel 111 and the second barrel 112, specifically, the installation space 114 may be formed between the inner wall of the second barrel 112 and the outer wall of the first barrel 111, and the installation space 114 may be used to store the protective film 120. The distal end of the second barrel 112 may be connected to the distal end of the first barrel 111, and the proximal end of the first barrel 111 may protrude from the proximal end of the second barrel 112, so that the user can more intuitively observe the relative position relationship between the protective film 120 and the first barrel 111, thereby facilitating the convenience of subsequent users to apply the film. A gap 113 may be provided between the proximal end of the second barrel 112 and the first barrel 111, and the gap 113 may be used for the protective film 120 located in the installation space 114 to move from the installation space 114 to the outside of the installation space 114 and to fit with the surface of the insertion portion 210. In this embodiment, the protective film 120 is disposed in the installation space 114 to prevent the protective film 120 from being contaminated before being fitted to the insertion portion 210.

[0054] It is understandable that, since the length of the insertion portion 210 is usually long, storing the protective film 120 in the installation space 114 can reduce the length space occupied by the protective film 120. The embodiment of the present application does not limit the specific manner of storing the protective film 120 in the installation space 114. For example, in one embodiment, the protective film 120 can be rolled up for easy storage in the installation space 114. For example, in another embodiment, the protective film 120 can be set to be stored in the installation space 114 in a folded state. The specific form can be set according to actual conditions.

[0055] In this embodiment, the protective film 120 may be formed with a first channel 121 for accommodating the inserting portion 210, the protective film 120 may be configured to have a proximal opening, the distal end of the first channel 121 may be configured to have a closed and transparent structure, and the distal end of the protective film 120 may be disposed in the sleeve mold 110, specifically, may be disposed in the interior of the first cylinder 111, at which time the outer surface of the protective film 120 is disposed opposite to the inner surface of the first cylinder 111, and a certain area between the distal end and the proximal end of the protective film 120 abuts against the end of the first cylinder 111, and the distal end of the protective film 120 abuts against the distal end of the protective film 120. The ends are both located in the first cylinder 111, and the aforementioned area and the proximal end of the protective film 120 are sleeved on the outer surface of the first cylinder 111. That is to say, in this embodiment, the protective film 120 is turned outward at the proximal end port of the through hole 1111 of the sleeve mold 110, and the outer surface of the protective film 120 is sleeved on the outer surface of the sleeve mold 110, specifically, it can be sleeved on the outer surface of the first cylinder 111, and in this embodiment, the wall thickness of the first cylinder 111 can be used to tighten the protective film 120, that is, the proximal end port and / or the outer surface of the through hole 1111 of the sleeve mold 110 are in a tightened state.

[0056] When the user needs to cover the insertion part 210, the insertion part 210 can be directly aligned with the first cylinder 111 and inserted into the first cylinder 111, so that the insertion part 210 contacts the inner surface of the protective film 120 in the first cylinder 111, and the insertion part 210 can be continuously inserted into the first cylinder 111. At this time, relative sliding can occur between the insertion part 210 and the covering mold 110, and the protective film 120 located in the installation space 114 can slide accordingly and fit on the outer surface of the insertion part 210, so that the protective film 120 is covered on the outer surface of the insertion part 210. Specifically, after the user inserts the insertion part 210 into the first barrel 111, the insertion part 210 can be extended from the first barrel 111, thereby facilitating continuous covering. When the covering is completed, the first barrel 111 is located at the proximal end of the insertion part 210. Since the proximal end of the insertion part 210 will not enter the patient's body, the endoscope 20 with covering can be directly used at this time. After the operator pulls the insertion part 210 out of the patient's body, the operator can directly hold the covering mold 110 and slide in the opposite direction of the covering to remove the protective film 120 from the surface of the insertion part 210.

[0057] Please refer again Figure 1-Figure 3, the glass slide 130 can be set at the distal end of the protective film 120, and the glass slide 130 can be used to dock the insertion part 210. It can be understood that since the distal end of the insertion part 210 is integrated with the lighting device and the image acquisition device, in order to ensure that the protective film 120 does not affect the image acquisition after the film is covered, the distal end of the insertion part 210 and the distal end of the protective film 120 can be set without any gap. During the production process of the protective film 120, it is inevitable that there is a tolerance, and it is difficult to avoid a gap between the protective film 120 and the insertion part 210. Therefore, the glass slide 130 can be used as an intermediate medium. When the user completes the covering of the insertion part 210, the insertion part 210 can be abutted against the glass slide 130, and the glass slide 130 can be abutted against the protective film 120. In this way, the aforementioned gap can be eliminated to ensure the accuracy of the image information acquired by the insertion part 210. It should be noted that the embodiments of the present application do not limit the specific form and structure of the glass slide 130. For example, in some embodiments, the glass slide 130 can be made of elastic and transparent materials such as resin or rubber. This not only helps to eliminate the aforementioned gaps, but also avoids the possibility of the glass slide 130 squeezing the distal end of the insertion part 210 and causing damage.

[0058] For further information, please also refer to Figure 5-Figure 11 In one embodiment, the insertion membrane assembly 10 may further include an instrument tube 30, which may also be sleeved in the protective membrane 120. Specifically, the protective membrane 120 may further form a second channel 122 parallel to the first channel 121, which may be used to accommodate the instrument tube 30. The second channel 122 may be through-set so that the medical device can extend from the second channel 122. In this embodiment, the instrument tube 30 may be detachably connected to the second channel 122, which may facilitate the assembly of the instrument tube 30 and the second channel 122. Meanwhile, the glass slide 130 may have a first region 131 and a second region 132, the insertion portion 210 may be docked and sealed in the first region 131, and the instrument tube 30 may be docked and sealed in the second region 132.

[0059] It should be noted that the embodiment of the present application does not limit the formation method of the first channel 121 and the second channel 122. For example, in one embodiment, the distal end of the protective film 120 can be set to a sealed state, and after the insertion part 210 and the instrument tube 30 are sleeved in the protective film 120, the second channel 122 can be opened separately.

[0060] For example, in another embodiment, the distal end of the protective film 120 may be preset with two channel openings, wherein the channel opening corresponding to the first channel 121 is sealed, and the channel opening corresponding to the second channel 122 is open, so that the insertion portion 210 and the instrument tube 30 can be used directly after being sleeved in the protective film 120.

[0061] For example, in another embodiment, the distal end of the protective film 120 can be through-through, and the distal end of the protective film 120 can be connected to the glass slide 130, and the first channel 121 in the protective film 120 is blocked, and the second channel in the protective film 120 is opened. The specific matching form can be set according to actual conditions and is not limited here.

[0062] The embodiment of the present application does not limit the specific structure and shape of the first area 131 and the second area 132. For example, in one embodiment, the cross-sections of the first area 131 and the second area 132 can be set to circular cross-sections so that the first area 131 and the second area 132 can match the insertion portion 210 and the instrument tube 30.

[0063] For example, in another embodiment, in the radial direction of the instrument tube 30, the second region 132 may be a semi-open region, and the open portion of the second region 132 is located on the side away from the first region 131, so that the size of the entire glass slide 130 can be reduced and the material consumption of the glass slide 130 can be saved. In this embodiment, the distal end of the second channel 122 can be surrounded by the glass slide 130 and the protective film 120.

[0064] Furthermore, in one embodiment, the second region 132 may be provided with a step surface 1321 for supporting the instrument tube 30 , and the step surface 1321 may be used to abut against the distal end of the instrument tube 30 to prevent the instrument tube 30 from penetrating too deeply into the protective film 120 .

[0065] In addition, in some embodiments, a tear strip 133 can be embedded in the protective film 120. The tear strip 133 can extend along the axial direction of the protective film 120 and extend out of the protective film 120 from the proximal end of the protective film 120. The tear strip 133 can facilitate the operator to tear off the protective film 120 along the tear strip 133 after use.

[0066] See also Fig.12 In a more specific embodiment, in the radial direction of the instrument tube 30, the length of the step surface 1321 is less than the wall thickness of the instrument tube 30. When the protective film 120 is sleeved on the outer surface of the instrument tube 30, the protective film 120 can squeeze the instrument tube 30 and force the instrument tube 30 to tilt toward the side wall above the step surface 1321. This can further make the connection between the instrument tube 30 and the protective film 120 tighter and reduce the size of the distal end of the entire instrument tube 30 after the sleeve is applied.

[0067] As mentioned above, please refer to Figure 3 and Figure 4In one embodiment, the proximal end of the second cylinder 112 may be provided with a limiting portion 1121 protruding toward the first cylinder 111. The limiting portion 1121 may be used to reduce the size of the connection between the installation space 114 and the outside world, thereby further preventing the protective film 120 in the installation space 114 from being contaminated before being installed.

[0068] In addition, the proximal end of the second barrel 112 may be provided with a hand-held portion 1122 protruding away from the first barrel 111, and the hand-held portion 1122 may facilitate the user to hold the film sleeve mold 110 when performing the film sleeve operation. Specifically, the user may hold the hand-held portion 1122 and apply a thrust to the hand-held portion 1122 toward the insertion portion 210, so that the protective film 120 can be quickly sleeved on the insertion portion 210.

[0069] In addition, the second cylinder 112 can be configured so that when subjected to radial extrusion force, its proximal end can retract radially to squeeze the portion of the protective film 120 that passes through the gap 113. That is to say, when the user holds the sleeve mold 110, the user can make full use of the force applied to the second cylinder 112 along the radial direction of the second cylinder 112 by the user. This force can squeeze the protective film 120, thereby facilitating tightening the protective film 120.

[0070] It is understandable that if the hand-held portion 1122 is not provided, the user can only hold the first cylinder 111. At this time, when an external force is applied to the first cylinder 111 for film covering, the force applied to the film covering mold 110 is friction force. After the hand-held portion 1122 is provided, the force applied to the film covering mold 110 is pressure. Since the friction force can be obtained by multiplying the pressure by the dynamic friction coefficient, the film covering with a structure without the hand-held portion 1122 requires greater force to obtain mechanical energy. In other words, the provision of the hand-held portion 1122 can also save effort.

[0071] In addition, in one embodiment, the aperture of the proximal end of the sleeve mold 110 can be larger than the aperture of the distal end of the sleeve mold 110, and the aperture of the sleeve mold 110 tends to gradually increase from the distal end to the proximal end. Specifically, the aperture of the proximal end of the first cylinder 111 can be larger than the aperture of the distal end of the sleeve mold 110. It can be understood that since the distal end of the insertion part 210 is connected to the handle part of the endoscope 20, the distal end size of the insertion part 210 will be larger than the proximal end size of the insertion part 210, so the aforementioned sleeve mold 110 can play a role in facilitating the sleeve.

[0072] In addition, in some embodiments, the cross-sectional size of the proximal end of the first cylinder 111 may also be larger than the cross-sectional size of the distal end of the sleeve mold 110, so that the protective film 120 can be stretched tighter when sleeved on the proximal end of the first cylinder 111, thereby facilitating subsequent sleeve coating.

[0073] In one embodiment, the proximal end of the protective film 120 can be connected to the outer surface of the first barrel 111, so as to avoid the proximal end of the protective film 120 from being knotted or stuck in the installation space 114, which is not conducive to the film covering operation. In addition, connecting the proximal end of the protective film 120 to the outer surface of the first barrel 111 can make the outer surface of the first barrel 111 straighten the protective film 120, further play the role of tightening the protective film 120, especially the process of covering the proximal end of the protective film 120, so as to ensure that the protective film 120 always remains in a taut state during the entire covering process. Similarly, in another embodiment, the proximal end of the protective film 120 can also be connected to the inner surface of the second barrel 112, which can also play the role of tightening the protective film 120.

[0074] It should be noted that the embodiment of the present application does not limit the specific connection method between the proximal end of the protective film 120 and the outer surface of the first cylinder 111. For example, in one embodiment, the proximal end of the protective film 120 can be connected to the first cylinder 111 in the form of a stamp hole, that is, the connection between the proximal end of the protective film 120 and the first cylinder 111 is intermittent, which can facilitate the user to separate the protective film 120 from the first cylinder 111 when pulling the first cylinder 111 forcefully, and the protective film 120 will also bounce toward the insertion part 210, so that the protective film 120 can be tightly connected to the insertion part 210.

[0075] For further information, please also refer to Figure 13-Figure 15 In some embodiments, the inserting membrane assembly 10 may further include a base 140, the base 140 may be provided with a plug hole 141, the distal end of the film sleeve mold 110 may be connected to the base 140, and the film sleeve mold 110 is provided corresponding to the plug hole 141. Specifically, the first cylinder 111 may be provided corresponding to the plug hole 141. The provision of the base 140 can free one hand of the user, that is, the base 140 can be used to fix the film sleeve mold 110, and the user can complete the film sleeve operation with only one hand when performing the film sleeve operation. Specifically, the user only needs to assist the inserting part 210 and extend the inserting part 210 into the first cylinder 111 to complete the film sleeve operation.

[0076] Furthermore, in one embodiment, a skirt 142 may be provided at the distal end of the base 140, and a through fixing hole 143 may be provided on the skirt 142. In this embodiment, the user can use the fixing hole 143 to fix the base 140 on a desktop or other operating surface during film application to prevent the base 140 from sliding during the film application process, thereby preventing the film application process from being adversely affected.

[0077] Also, see Figure 16-18In one embodiment, the insertion membrane assembly 10 may further include an upper cover 150, which is detachably connected to the base 140, and a closed space 151 may be formed between the upper cover 150 and the base 140, and the protective film 120 may be located in the closed space 151, which may further reduce or avoid the possibility of the protective film 120 being contaminated before the film is applied. The embodiment of the present application does not limit the connection method between the upper cover 150 and the base 140, for example, it may be a threaded connection, or an interference connection, etc., which may be specifically set according to actual conditions and is not limited here.

[0078] It is understandable that, in other embodiments, the upper cover 150 may be detachably connected to the second cylinder 112, which may also reduce or avoid the possibility of the protective film 120 being contaminated before being covered.

[0079] In summary, the insertion membrane assembly 10 provided in the embodiment of the present application is configured such that the first channel 121 in the protective film 120 is set to a state in which the distal end is sealed and transparent, and the distal end of the protective film 120 is set in the through hole 1111 of the film sleeve mold 110, and the protective film 120 is turned outward at the proximal end port of the through hole 1111 of the film sleeve mold 110. At this time, the proximal end port and / or part of the outer surface of the protective film 120 at the through hole 1111 of the film sleeve mold 110 are in a taut state, and a glass slide 130 for docking with the insertion part 210 is set at the distal end of the protective film 120. When the user needs When the inserting part 210 is covered with film, the inserting part 210 can be directly inserted into the through hole 1111 of the covering mold 110, and the distal end of the inserting part 210 is brought into contact with the glass slide 130, and then the inserting part 210 or the covering mold 110 is pushed so that the protective film 120 can gradually and tightly fit on the outer surface of the inserting part 210. Since the outer surface of the protective film 120 and the outer surface of the covering mold 110 are in a taut state, when the protective film 120 is in contact with the surface of the inserting part 210, it is also in a taut state, thereby achieving the operation of covering the outer surface of the inserting part 210.
