Description

Insert membrane module and endoscope module

Technical Field

The invention relates to the field of endoscopes, in particular to an insertion part membrane assembly and an endoscope assembly.

Background

Endoscopes are one of the diagnostic and therapeutic tools widely used in the field of modern medicine, and particularly play an irreplaceable role in gastroenteroscopy, bronchoscopy, cystoscopy and the like. However, since the endoscope directly contacts the digestive tract, respiratory tract, etc. of the patient, there is a high risk of infection, strict cleaning and sterilization must be performed after each use to ensure patient safety. This sterilization process typically involves multiple steps of mechanical cleaning, chemical sterilization, oven sterilization, etc., requiring very expensive equipment and consumables, and long periods of time. Therefore, the cost of disinfection and reprocessing of endoscopes has become a significant cost burden for medical institutions, especially in the case of large patient volumes.

To reduce the cost of sterilization and to increase the efficiency of use, disposable endoscopes have been developed. The disposable endoscope solves the problems of high cost, complex disinfection flow and high infection control difficulty caused by repeated disinfection by reducing the disinfection steps of the traditional endoscope. The quick use and safety of disposable endoscopes is particularly important in departments that are particularly sensitive to risk of infection, such as emergency treatment, intensive care, and the like. However, although disposable endoscopes have significant advantages in certain situations, the production costs are still high, and in particular, the manufacture of the core components such as endoscope lenses, sensors, etc. requires elaborate technical processes. In addition, disposable endoscopes are discarded after use, producing a large amount of medical waste. Because medical waste needs to be subjected to a special treatment program to avoid negative effects on the environment and public health, new environmental burden and treatment cost are generated, and the comprehensive expenditure of hospitals is further improved.

The following describes in detail an insertion portion membrane module 10 and an endoscope module 1 provided by the present application with reference to fig. 1 to 8 by way of specific embodiments and application scenarios thereof.

Referring to fig. 1 and 2, an embodiment of the present application provides an insert film assembly 10, where the insert film assembly 10 may be used for an endoscope 90, the endoscope 90 may include an insert 80, and the insert film assembly 10 may be used to be sleeved on an outer surface of the insert 80, so as to prevent the insert 80 from being polluted by an external environment.

Referring also to fig. 2-4, the insert membrane assembly 10 may include a front end housing 110, a membrane body 20, and an instrument tube 30. Both the membrane 20 and the instrument tube 30 may be connected to the front end housing 110, in this embodiment the front end housing 110 may serve as a mounting base. The embodiment of the present application 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, so that the membrane body 20 and the instrument tube 30 may be conveniently connected to the front end seat 110, and the embodiment of the present application also does not limit the connection manner of the membrane body 20 and the front end seat 110, and does not limit the connection manner of the instrument with respect to the front end seat 110, so long as the connection is sealed, for example, in one embodiment, the connection may be performed by adopting a welding manner, and may be specifically set according to practical situations.

Further, the distal end of the front end seat 110 may be disposed in a transparent manner, so that the endoscope 90 can observe the external environment, and the front end seat 110 has a sealing area 111 and an open area 112 in the radial direction, the sealing area 111 may be used to accommodate the insertion portion 80, so as to prevent the insertion portion 80 from being contaminated by the external environment, and the open area 112 may be used to accommodate the instrument tube 30, so that the medical instrument extends out of the instrument tube 30, and thus the operator can perform the operation on the patient. It will be appreciated that the instrument tube 30 and medical instrument may be of disposable construction, and that these elements may be produced at low cost, with a disposable arrangement being advantageous for saving time and additional costs associated with the sterilization process. It will be appreciated that in some other embodiments, the instrument tube 30 and the medical device may be configured to be reusable, and also because the instrument tube 30 and the medical device are manufactured at low cost, a large number of instrument tubes 30 and medical devices may be prepared, and after use, the medical devices may be sterilized in a low-cost and long-time sterilization manner for reuse, thereby reducing the cost of use of the endoscope 90.

Further, in some embodiments, the front end seat 110 may be provided with a limiting block 113 protruding into the mounting channel 210, and the limiting block 113 may be used to assist in clamping the insertion portion 80, so that the insertion portion 80 is more tightly connected with the film body 20 after the film is sleeved, which reduces the probability that the film body 20 falls off from the insertion portion 80, and is beneficial to ensuring that the insertion portion 80 is not polluted by the external environment. It should be understood that the specific positions and numbers of the limiting blocks 113 are not limited in the embodiments of the present application, and may be specifically and adaptively set according to the specific structure of the front end seat 110, for example, in this embodiment, a partial area of the front end seat 110 may extend in the second direction 50, and the limiting blocks 113 may be disposed on the inner wall of the aforementioned area extending in the second direction 50.

The membrane body 20 may have a mounting channel 210 formed therein, and the membrane body 20 may be sealingly coupled to the front end housing 110 and extend in the first direction 40. Specifically, in the present embodiment, the membrane 20 may be configured as a cylindrical structure, and the membrane 20 may have a first surface and a second surface opposite to each other, where the first surface may be an inner surface, the second surface may be an outer surface, and the first surface may be sealingly connected to the front end seat 110. When the user performs the film coating operation on the insert portion 80, the insert portion 80 may be aligned with the mounting channel 210, at this time, the insert portion 80 contacts the first surface of the film body 20, and then the user may push the insert portion 80 to move in the first direction 40 to implement reverse film coating, in this process, the first surface is attached to the insert portion 80, and after the user completes film coating, the first surface is changed from the original inner surface to the outer surface.

Referring to fig. 5-7, in one embodiment, the distal end of the membrane body 20 may be provided with a support ring 220, and the support ring 220 may have a larger dimension than the membrane body 20, and it is understood that the dimension herein refers to a cross-sectional dimension along the axial direction of the membrane body 20, which may facilitate the use of the support ring 220 for more convenient membrane sheathing during membrane sheathing. It should be noted that the distal end refers to the distal end of the membrane 20 before being sleeved on the insertion portion 80, and the support ring 220 is located at the proximal end of the membrane 20 after the membrane 20 is sleeved on the insertion portion 80. It will be appreciated that as the membrane 20 is gradually nested toward the proximal end of the insertion portion 80, the proximal end of the insertion portion 80 will generally be sized slightly larger than the front end of the insertion portion 80, so that the support ring 220 may be configured to more closely match the portion of the membrane 20 that is in contact with the insertion portion 80.

The instrument tube 30 may be sealingly connected to the open area 112 and extend in the second direction 50, with the interior of the instrument tube 30 disposed therethrough to form an instrument channel 310, the instrument channel 310 being operable for passage of a medical instrument therethrough. In the present embodiment, the second direction 50 is opposite to the first direction 40, and when the user performs the film coating operation on the insertion portion 80, the insertion portion 80 and the instrument tube 30 may be simultaneously moved in the first direction 40 together to perform the film coating process on the insertion portion 80 and the instrument tube 30. That is, in the present embodiment, the instrument channel 310 is located inside the mounting channel 210 and occupies a part of the area of the mounting channel 210, and the remaining area of the mounting channel 210 can be used as the area for accommodating the insertion portion 80.

With continued reference to fig. 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, an instrument plug, etc., and may be specifically set according to circumstances, for example, when the operator needs to aspirate foreign objects in the patient using the endoscope 90, the functional device 910 may be provided as a negative pressure valve and apply a negative pressure thereto to aspirate foreign objects in the patient. It should be noted that, in this embodiment, the functional device 910 may be detachably connected to the instrument tube 30, so that an operator may conveniently connect different functional devices 910 for different situations.

With continued reference to fig. 5-7, in one embodiment, the insert membrane assembly 10 may further include an auxiliary assembly 60, wherein the auxiliary assembly 60 may be used to assist a user in straightening the insert 80 to facilitate a membrane covering operation of the insert 80. The auxiliary assembly 60 is removably disposed at the distal end of the instrument channel 310 and extends beyond the area encompassed by the membrane 20 in the first direction 40 to facilitate pulling of the auxiliary assembly 60 by a user.

In one particular embodiment, the auxiliary assembly 60 may include a plug 610 and a tether 620, the plug 610 being removably disposed at the distal end of the instrument channel 310, the tether 620 being attachable to the plug 610 and extending in the first direction 40 and out of the area enclosed by the membrane 20. It should be noted that, in the embodiment of the present application, the specific connection manner of the rope 620 and the plug 610 is not set, for example, in one embodiment, the rope 620 may be integrally formed with the plug 610, so that the consistency of the rope 620 and the plug 610 may be improved, and further the possibility of tearing the rope 620 and the plug 610 may be avoided or reduced.

In addition, referring to FIGS. 5-7, in some embodiments, the insert membrane assembly 10 may further include a support assembly 70, wherein the support assembly 70 may be sleeved outside the front end seat 110. It will be appreciated that since the membrane 20 is a soft elastic material and the insertion portion 80 is also a soft elastic material, there may be a case where the covering film is slow in the process of fitting the membrane 20 into the insertion portion 80. The support assembly 70 may thus be used to support the membrane 20, thereby facilitating the insertion of the membrane 20 over the insert 80.

The embodiment of the present application is not limited to the specific structure of the support assembly 70, for example, in some embodiments, the insertion assembly may be configured to resemble a funnel, that is, the support assembly 70 may have a first end 710 and a second end 720 opposite to each other, wherein the second end 720 has a size larger than that of the first end 710, the first end 710 is sleeved outside the front seat 110, and the foregoing configuration may facilitate the sleeving of the support assembly 70 to the front seat 110.

In addition, in one embodiment, the support assembly 70 may be configured in a hollow cylindrical configuration, and after the insertion portion 80 is completely covered, it is generally necessary to coat the outer surface of the membrane body 20 with a layer of lubricating oil so that the insertion portion 80 can move more smoothly in the patient's body. The foregoing construction of the support assembly 70 thus facilitates oiling the exterior of the film body 20. Specifically, when the user needs to apply oil, the lubricant may be directly poured into the support assembly 70 from the second end 720, and the user may finish the oil applying operation to the membrane body 20 during the process of taking out the support assembly 70 from the insertion portion 80.

In one embodiment, the support assembly 70 may further have a stop collar 730, where the stop collar 730 may be disposed between the first end 710 and the second end 720, where the stop collar 730 may be disposed to protrude away from the instrument channel 310, where the stop collar 730 may be used to limit the position of the membrane 20 so that the membrane 20 is in a tight condition prior to contact with the insert 80, and thus may facilitate a better fit of the membrane 20 to the outer surface of the insert 80.

Further, referring to fig. 7 and 8, in an embodiment, a portion of the membrane 20 may be folded or folded, so that the length occupied by the membrane 20 may be reduced, and thus the insertion portion membrane assembly 10 may be stored or transported. In a more specific embodiment, the pleated or folded region of the membrane 20 is disposed adjacent the support ring 220.

The assembly process and the working principle of the insert membrane assembly 10 according to the embodiment of the present application will be described below:

The membrane body 20 may be aligned first with the sealing region 111 and the front end seat 110 sealingly coupled to the membrane body 20, with the membrane body 20 extending in the first direction 40, then the instrument tube 30 aligned with the open region 112, then the instrument tube 30 sealingly coupled to the front end seat 110, with the instrument tube 30 extending in the second direction 50, then the insertion portion 80 aligned with the mounting channel 210. Then, the front end seat 110 is fixed, and the insertion portion 80 and the instrument tube 30 are pushed towards the first direction 40 at the same time, so that the insertion portion 80 and the instrument tube 30 are sleeved inside the membrane body 20, and the membrane assembly 10 of the insertion portion performs membrane sleeving operation on the insertion portion 80 and the instrument tube 30.
