Description

Technical Field

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

[0002] An endoscope is a medical diagnostic instrument that integrates an image sensor, optical lens, light source, and mechanical devices. It can enter the human body to capture images for diagnosis. When storing an endoscope after use, a protective sleeve is usually used to cover the end with the lens, providing good protection for the critical parts of the endoscope.

[0003] Currently, there are two common types of protective sleeves used for endoscopes. One type is designed with a corresponding inner diameter size for endoscopes of different outer diameter sizes. The disadvantage of this type of protective sleeve is that, since each protective sleeve is only adapted and compatible with one type of endoscope, the number of protective sleeve types also increases when there are many types of endoscopes.

[0004] Therefore, some manufacturers have developed another type of protective sleeve that can accommodate various sizes of endoscopes. This type of sleeve has multiple silicone films along the length of the lumen used to house the endoscope, and these films have cross-shaped slots. These cross-shaped slots serve as mounting and positioning openings for the protective sleeve. When the endoscope passes through these slots, the silicone films clamp the surface of the endoscope, preventing it from slipping out of the sleeve and thus protecting it.

[0005] This type of protective sleeve has the following drawbacks: when the radial dimension of the endoscope is large, the silicone film can still clamp the surface of the endoscope and provide protection; however, when the radial dimension of the endoscope is small, the silicone film often cannot clamp the surface of the endoscope well, which will cause the endoscope to loosen from the protective sleeve, resulting in the endoscope not being well protected. Utility Model Content

[0006] To address the shortcomings of existing technologies, this application provides an endoscope protective sleeve that solves the problems of not being able to be used with multiple different endoscopes simultaneously and the sleeve not clamping securely.

[0007] To achieve the above objectives, this application provides the following technical solution: an endoscope protective sleeve, comprising a tube sleeve, wherein one end of the tube sleeve is provided with a tube opening, and the interior of the tube sleeve is a cavity connected to the tube opening;

[0008] The lumen includes tubes of various radial dimensions, and the tubes of different radial dimensions are adapted to endoscopes of different radial dimensions respectively;

[0009] Within the pipe, the radial dimension of the pipe gradually decreases from the pipe opening in a direction away from the pipe opening.

[0010] Preferably, the tube sleeve includes a tube frame and several semi-ring sleeves; the tube frame includes two fixed rods; each semi-ring sleeve spans between the two fixed rods, and its two ends are respectively connected to the two fixed rods.

[0011] Preferably, the two center lines of the two fixed rods form a central plane; the plurality of semi-rings are arranged in an array to form a first semi-ring group and a second semi-ring group.

[0012] The first semi-ring sleeve group is distributed on the first side of the axial center plane, and the second semi-ring sleeve group is distributed on the second side of the axial center plane; and the semi-ring sleeves that make up the first semi-ring sleeve group and the semi-ring sleeves that make up the second semi-ring sleeve group are staggered on the pipe rack.

[0013] Preferably, the thickness of the middle part of the semi-ring is less than the thickness of the two ends of the semi-ring; the middle part of the semi-ring refers to the portion of the semi-ring that connects to the two ends.

[0014] Preferably, each of the semi-rings has an opening in the middle.

[0015] Preferably, the sleeve is provided with a lug at the other end away from the tube opening.

[0016] Preferably, the sleeve is made of an elastic material; the elastic material includes rubber or silicone.

[0017] Preferably, the nozzle is covered with a film made of the elastic material, and the film has grooves.

[0018] Preferably, the groove is configured as one of the following shapes: a cross shape, a rice-shaped shape, and a letter "Y".

[0019] Preferably, the film is further provided with dashed grooves, which are distributed along the groove.

[0020] Preferably, the film includes a first state and a second state, and the film can be unidirectionally transformed from the first state to the second state. When the film is in the first state, the endoscope does not enter the lumen, and when the film is in the second state, the endoscope can at least partially enter the lumen.

[0021] Preferably, the raw materials include the following parts by weight: PLA 40%-50%, peanut protein powder 20%-30%, lignocellulose 10%-5%, surface-modified chitin whiskers 10%-5%, silicone rubber 5-2.5%, hard clay 5-2.5%, photosensitizer 5-2.5%, toughening agent 2.5-1%, amylose 10%-5%, and dehydroacetic acid 5-2.5%.

[0022] Working principle: PLA (polylactic acid), also known as polylactide, is a polyester polymer obtained by polymerization of lactic acid as the main raw material. PLA products are biodegradable and have good biocompatibility, gloss, transparency, feel, and heat resistance. Peanut protein powder refers to peanut oil produced from selected high-quality peanuts through processes such as removing the red skin, cold pressing at 60℃, and filtration. Cold-rolled cake is a product obtained through crushing, subcritical biotechnology low-temperature extraction, crushing, and sterilization. Lignocellulose is non-toxic, odorless, pollution-free, and non-radioactive, possessing excellent flexibility and dispersibility. Surface-modified chitin whiskers are soluble in dimethylacetamide containing 8% lithium chloride or concentrated acid. Silicone rubber refers to rubber whose main chain consists of alternating silicon and oxygen atoms, with two organic groups usually attached to the silicon atoms. Silicone rubber is non-toxic, odorless, tasteless, does not adhere to human tissue, and has anticoagulant properties. It exhibits very low reactivity to body tissues, making it particularly suitable as a medical material. Hard clay is malleable; wet clay can be molded into various shapes without breaking and can remain unchanged for a long time. Photosensitizers prevent yellowing and aging of the cured protective sleeve. Toughening agents increase the flexibility of the adhesive film layer of the protective sleeve. Amylose has properties similar to fiber; films made from amylose have good transparency, flexibility, tensile strength, and water insolubility, and can be used in the production of sealing materials, packaging materials, and water- and pressure-resistant materials. It has certain antibacterial effects under acidic and alkaline conditions, especially against mold. Endoscope protective sleeves made from the above raw materials have good degradability, as well as certain transparency, toughness, and anti-aging properties, and also have certain antibacterial effects.

[0023] This application provides an endoscope protective sleeve. It has the following beneficial effects:

[0024] This application utilizes the lumen of the endoscope protective sleeve to accommodate endoscope tips of different radial dimensions. When an endoscope tip with a corresponding outer diameter passes through the tube opening, the endoscope tip can be correspondingly snapped into the tube of the corresponding outer diameter, allowing the endoscope tip to be stably assembled inside the sleeve after passing through the tube opening.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0033] Example 1:

[0034] like Figure 1 and Figure 2 As shown, the endoscope protective sleeve 100 provided in this application embodiment may include: a tube sleeve 10.

[0035] The sleeve 10 has an opening 11 at one end, and the inside of the sleeve 10 is a cavity 12 that communicates with the opening 11. The opening 11 is for the end of the endoscope with a lens (hereinafter referred to as "endoscope end") to pass through, and the cavity 12 is for accommodating the endoscope end that passes through the opening 11.

[0036] The lumen 12 includes tubes of various radial dimensions (first tube 121, second tube 122, and third tube 123), with each tube of different radial dimensions being adapted to an endoscope of different radial dimensions. Within the tubes, the radial dimensions of the tubes gradually decrease from the opening 11 in the direction away from the opening 11.

[0037] Specifically, the conduit may include a first conduit 121, a second conduit 122, and a third conduit 123. Within the lumen 12, the radial dimensions of the first conduit 121, the second conduit 122, and the third conduit 123 gradually decrease from one end of the opening 11 towards a direction away from the opening 11, respectively corresponding to large, medium, and small endoscopes. In this embodiment, the radial dimension of the large endoscope may be 13–20 mm, the radial dimension of the medium endoscope may be 8–12 mm, and the radial dimension of the small endoscope may be 2.5–5 mm.

[0038] It should be noted that the term "gradual" refers to the radial dimension of the endoscope lumen 12 within the endoscope protective sleeve 100, from the orifice 11 towards the direction away from the orifice 11, being a set of values ​​that gradually decrease from large to small, exhibiting a step-like change. This differs from the continuous tapering decrease from the orifice 11 towards the direction away from the orifice 11. Of course, the radial dimension of the endoscope lumen 12 can also decrease continuously in a tapering manner from the orifice 11 towards the direction away from the orifice 11.

[0039] Through the above design, the endoscope protective sleeve 100 allows its lumen 12 to be adapted to endoscope tips of different radial dimensions. When an endoscope tip with a corresponding outer diameter passes through the opening 11, the endoscope tip can be correspondingly snapped into the pipe of the corresponding outer diameter, so that the endoscope tip can be stably assembled in the sleeve 10 after passing through the opening 11. In some situations (such as transportation, storage, and disinfection), the endoscope protective sleeve 100 can reliably cover and protect the endoscope tip.

[0040] In this embodiment, the sleeve 10 or endoscope protective sleeve 100 can be made of an elastic material, and the elastic material can be, but is not limited to, the currently more common rubber or silicone.

[0041] In some embodiments, in order to prevent the endoscope from falling out of the endoscope protective sleeve 100 after the endoscope tip is housed in the endoscope protective sleeve 100, the radial dimension of each channel of the endoscope protective sleeve 100 can be designed to be slightly smaller than the radial dimension of the endoscope tip to which each channel is fitted.

[0042] When the endoscope tip passes through the tube opening 11, because the radial dimension of the endoscope protective sleeve 100 is smaller than the radial dimension of the endoscope tip, the endoscope tip can squeeze the inner wall of the tube, causing the tube to deform under pressure. As a result, the tube generates an elastic covering force of a certain magnitude, so that the endoscope tip can be securely covered within the tube opening 12.

[0043] like Figure 2 In some embodiments, the tube sleeve includes a tube frame and a plurality of semi-ring sleeves 13. The tube frame includes two fixing rods 14; each semi-ring sleeve 13 spans between the two fixing rods 14, with its two ends connected to the two fixing rods 14 respectively. Thus, the two fixing rods 14 and the plurality of semi-ring sleeves 13 are connected to form the overall base frame of the endoscope protective sleeve 100.

[0044] Specifically, the two fixed rods 14 can be parallel to each other or they can approach each other at a predetermined angle. The centerlines of the two fixed rods 14 (first centerline X1 and second centerline X2) form a plane, which is referred to as the axial plane for ease of description.

[0045] like Figure 3 On the sleeve 10, with the axial plane formed by the axis lines (first axis line X1 and second axis line X2) as the boundary, multiple semi-ring sleeves 13 can be divided into a first semi-ring sleeve group R1 and a second semi-ring sleeve group R2. The multiple semi-ring sleeves 13 are arranged in an array to form the first semi-ring sleeve group R1 and distributed on the first side of the axial plane. The multiple semi-ring sleeves 13 are arranged in an array to form the second semi-ring sleeve group R2 and distributed on the second side of the axial plane. Furthermore, the semi-ring sleeves 13 of the first semi-ring sleeve group R1 and the semi-ring sleeves 13 of the second semi-ring sleeve group R2 are staggered on the pipe rack.

[0046] Of course, the semi-ring sleeve 13 of the first semi-ring sleeve group R1 and the semi-ring sleeve 13 of the second semi-ring sleeve group R2 can also be arranged opposite to each other on the pipe rack. That is, the two ends of the semi-ring sleeve 13 on the first side (first semi-ring sleeve group R1) and the two ends of the semi-ring sleeve 13 on the second side (second semi-ring sleeve group R2) are connected at the same position on the two fixed rods 14, and the semi-ring sleeve 13 on the first side (first semi-ring sleeve group R1) and the semi-ring sleeve 13 on the second side (second semi-ring sleeve group R2) form a ring.

[0047] Compared to the opposite arrangement of the two semi-ring sleeves 13, the staggered arrangement of the two semi-ring sleeves 13 can distribute the covering force along the length of the endoscope to the endoscope tip. The endoscope protective sleeve 100 distributes the covering force of the endoscope tip more dispersedly, which can prevent the endoscope tip from being unable to enter the lumen 12 smoothly or be unable to be smoothly removed from the lumen 12 due to excessive covering force.

[0048] like Figure 1 In some embodiments, the thickness of the middle portion 131 of the semi-ring sleeve is less than the thickness of the end portion 132 of the semi-ring sleeve. It should be noted that the middle portion 131 of the semi-ring sleeve refers to the part of the semi-ring sleeve 13 connected between the two ends 132 of the semi-ring sleeve, and the end portions 132 of the semi-ring sleeve refer to the two ends of the semi-ring sleeve 13 used to connect with the fixing rod 14; the thickness refers to the radial dimension of the endoscope protective sleeve 100.

[0049] The advantage of this design of the semi-ring sleeve 13 is that the semi-ring sleeve 13 is connected to the fixing rod 14 with the thicker end 132, which can ensure the connection strength between the semi-ring sleeve 13 and the fixing rod 14. During the process of the endoscope tip entering the lumen of the endoscope protective sleeve 100, the thinner middle part 131 of the semi-ring sleeve is conducive to better deformation, allowing the endoscope tip to enter the lumen 12 of the endoscope protective sleeve 100 more easily.

[0050] Please continue reading. Figure 1 In some embodiments, each semi-ring sleeve 13 may have a through-hole 133 in the middle. The design of the through-hole 133 is beneficial to further improve the elastic deformation capability of the middle part 131 of the semi-ring sleeve, so that after the endoscope tip enters the lumen 12, each semi-ring sleeve 13 can cover the surface of the endoscope with a more suitable elastic covering force, which becomes a pre-tightening force to prevent the endoscope from loosening from the endoscope protective sleeve 100.

[0051] The opening 11 is provided with a thin film 15 made of the aforementioned elastic material, which covers the opening 11. The thin film 15 is provided with a groove 151, and the thickness of the thin film 15 in the groove 151 is less than the thickness of the thin film 15 outside the groove 151. This is to facilitate the endoscope tip to be easily pierced by the thinner groove 151 when the endoscope tip is covered by the endoscope protective sleeve 100, so that the endoscope tip can smoothly enter the lumen 12.

[0052] In this embodiment, the groove 151 can be set to a cross shape, a rice-shaped shape, or a letter "Y" shape. Its shape can be designed into a suitable shape according to actual needs. This embodiment does not specifically limit the shape of the groove 151.

[0053] like Figure 4 In some embodiments, to facilitate better puncture of the film 15, a plurality of slots 152 communicating with the cavity 12 can be formed on the film 15 along the extending direction of the groove 151 at the bottom of the groove 151. The plurality of slots 152 are distributed in a dotted line shape within the groove 151. For ease of description, the plurality of slots 152 distributed in a dotted line shape will be referred to as "dotted line slots 152" below.

[0054] When the endoscope tip punctures the membrane, due to the dotted groove 152 design, the membrane will be directionally torn open along the direction of the dotted groove 152, allowing the endoscope tip to pass through the opening and enter the lumen 12. Therefore, the dotted groove 152 design effectively reduces burrs generated at the edge of the opening after the membrane 15 is torn, improving the membrane 15's coverage and positioning effect on the endoscope tip.

[0055] It should be noted that the groove 151 and the dotted groove 152 on the aforementioned membrane 15 not only facilitate the endoscope tip to pierce the membrane 15, but also serve a certain marking function. That is, the user can determine whether the endoscope protective sleeve 100 has been used by observing the state of the groove 151 and the dotted groove 152, thereby avoiding the user from using the endoscope protective sleeve 100 repeatedly. For example, when the groove 151 and the dotted groove 152 are pierced and an opening is made in the membrane 15, the endoscope protective sleeve 100 is clearly in use or has been used, and the user can replace it with another endoscope protective sleeve 100.

[0056] In some embodiments, the film 15 includes a first state and a second state, and the film 15 can unidirectionally change from the first state to the second state. When the film 15 is in the first state, the endoscope does not enter the lumen 12. When the film 15 is in the second state, the endoscope can at least partially enter the lumen 12. It is understood that the first state of the film 15 refers to the state where the groove 151 and / or the dotted groove 152 located thereon are not punctured, at which time the endoscope does not enter the lumen 12. The second state of the film 15 refers to the state where the groove 151 and / or the dotted groove 152 located thereon are punctured, at which time an opening is made on the film 15, and the endoscope tip can be inserted into the lumen 12 through the opening.

[0057] like Figure 2 In some embodiments, a hanging ear 20 may be provided at the other end of the sleeve 10, which is separate from the opening 11, as needed. The hanging ear 20 is connected between the ends of the two fixing rods 14. After the endoscope is assembled inside the endoscope protective sleeve 100, the endoscope protective sleeve 100 containing the endoscope can be hung in a designated position through the hanging ear 20, saving space.
