Description

Technical Field

[0001] This utility model relates to the field of human daily necessities, and more particularly to medical devices, especially a protective device for a medical endoscope. Background Technology

[0002] In endoscopic diagnosis and treatment, fiber optic beams are essential for light transmission. These beams, composed of glass fiber optic leads, can break if bent or squeezed by the surgeon, concentrating light energy at the break point and potentially burning the surgeon or surgical attachments. Fiber optic beams are consumables, expensive, and not supplied sterile; improper handling can lead to infection. Currently, two sterile protective sleeves are used in clinical practice to isolate the imaging system and beam to achieve sterility. However, scrub nurses must prepare these sleeves before surgery. Scrub nurses and circulating nurses must maintain sterility during the connection of the endoscopic system, but the limited operating space, lack of physical isolation, and easy hand contact by the operator can contaminate the surgical field, making the procedure time-consuming and labor-intensive. If the sterile protective sleeve dislodges during surgery, it disrupts the sterile barrier, adding extra work and delaying the procedure.

[0003] In the prior art, for example, CN211834518U discloses a laparoscopic protective sleeve device, which uses a detachable snap-fit ​​component to connect with the camera system. Although it can protect the camera system, it does not protect the beam guide. The beam guide and the snap-fit ​​component are prone to squeezing and bending, which may cause damage to the beam guide.

[0004] Furthermore, CN219021111U discloses a disposable beam guide protective sleeve, consisting of two elastic sleeves and a pre-tightening mechanism, used to attach and fix the beam guide. However, it does not establish a sterile barrier during the connection process, and the preparation steps are cumbersome; the sterile barrier is easily damaged during the connection and use of the endoscope system. Summary of the Invention

[0005] The purpose of this invention is to provide a medical endoscope protection device that solves the technical problem of poor beam guide protection in the prior art, which may lead to damage.

[0006] This utility model discloses a medical endoscope protection device, comprising a first body and a second body. Both the first body and the second body are flexible cylindrical structures with openings at both ends. One end of the second body is a lens outlet, and a connecting interface is provided on the side of the lens outlet. The opening at one end of the first body is sealed to the connecting interface. A support and protective frame is provided on the inner side of the first body at the connection with the connecting interface. The lens outlet is a converging port.

[0007] Furthermore, both the first and second sleeves are transparent plastic film sleeves.

[0008] Furthermore, the support and protective frame is funnel-shaped.

[0009] Furthermore, the support and protective frame includes multiple ring-shaped bodies arranged from top to bottom, with the diameter of the multiple ring-shaped bodies decreasing sequentially from top to bottom, and adjacent ring-shaped bodies being connected by ribs.

[0010] Furthermore, the height of the support and protective frame is 15cm, the diameter of the upper ring is 10cm, and the diameter of the lower ring is 5cm.

[0011] Furthermore, a pull cord is provided inside the lens outlet.

[0012] Compared with existing technologies, the advantages of this invention are positive and significant. The first and second sets of this invention are connected via an interface, preventing the protective sleeve from detaching during the connection and use of the endoscope system, thus preventing damage to the sterile barrier. The support and protective frame prevents the beam guide from bending or being squeezed during surgery, thus preventing damage to the beam guide. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0018] like Figures 1-2As shown, a protective device for a medical endoscope according to this utility model includes a first body 1 and a second body 2. Both the first body 1 and the second body 2 are flexible cylindrical structures with openings at both ends. One end of the second body 2 is a lens outlet 5, and a connection interface 4 is provided on the side of one end of the lens outlet 5. The opening at one end of the first body 1 is sealed to the connection interface 4. A support and protective frame 3 is provided on the inner side of the connection between the first body 1 and the connection interface 4. The lens outlet 5 is a converging port. Specifically, the first body 1 and the second body 2 can be flexible, foldable, or retractable cylindrical structures. The lens end of the endoscope 7 extends from the lens outlet 5. The central axis of the first body 1 intersects perpendicularly with the central axis of the second body 2, so that the direction of the first body 1 is adapted to the optical fiber end of the endoscope 7. The lens outlet 5 is a constriction port, which can be a conical structure or a flexible constriction structure. The constriction port wraps around the rear outer side of the lens end of the endoscope 7, so that the second body 2 and the endoscope 7 form a sterile barrier, and the lens end of the endoscope 7 can work.

[0019] Furthermore, both the first sleeve 1 and the second sleeve 2 are transparent plastic film sleeves. Specifically, the first sleeve 1 and the second sleeve 2 can be made of polypropylene material, and the unfolded length of the first sleeve 1 and the second sleeve 2 can be 2m and the width is 20cm, which can adapt to most usage scenarios.

[0020] Furthermore, the support and protective frame 3 is funnel-shaped. The lower end of the funnel-shaped support and protective frame 3 has a smaller diameter, which can be fitted over the optical fiber end of the endoscope 7 to limit the position of the support and protective frame 3. The upper end has a larger diameter, which allows the beam guide 8 to move within a certain range and provides support for the beam guide 8 through the upper end of the support and protective frame 3.

[0021] Furthermore, the support and protective frame 3 includes a plurality of annular bodies 31 arranged from top to bottom, the diameter of which decreases sequentially from top to bottom, and adjacent annular bodies 31 are connected by ribs 32. Specifically, the support and protective frame 3 can be made of polyethylene material, and the rib structure 32 provides a certain degree of elasticity between the annular bodies 31, allowing the support and protective frame 3 to flexibly support the beam guide 8.

[0022] Furthermore, the support and protective frame 3 has a height of 15cm, a diameter of 10cm for the upper ring 31, and a diameter of 5cm for the lower ring 31. These dimensions of the support and protective frame 3 are suitable for most applications of endoscopes 7.

[0023] Furthermore, a pull cord 6 is provided inside the lens outlet 5. Specifically, the material at one end of the lens outlet 5 of the second body 2 can be flipped to form a sealed ring, and a cotton rope is inserted into the ring as a pull cord 6. The lens outlet 5 is controlled by the pull cord 6, which can accommodate endoscope lenses 7 of different diameters.

[0024] When this utility model is used, Figure 3 As shown, firstly, the first set 1 and the second set 2 are folded together. Then, the endoscope 7 is inserted into the second set 2. The lens end of the endoscope 7 extends from the lens outlet 5 of the first set 1. The fiber optic end of the endoscope 7 is aligned with the interface 4. Then, the beam guide 8 passes through the first set 1 and the support and protective frame 3 and is connected to the beam guide interface of the endoscope 7. The camera cable 9 passes through the second set 2 and is connected to the camera interface of the endoscope 7. Finally, the first set 1 and the second set 2 are stretched so that the first set 1 covers the outside of the beam guide 8 and the second set 2 covers the outside of the camera cable 9.

[0025] The first sleeve 1 and the second sleeve 2 form a sterile barrier, maintaining a sterile environment outside the first sleeve 1 and the second sleeve 2 during the operation; the first sleeve 1 and the second sleeve 2 are connected by a sealed interface 4 to prevent the protective sleeve from falling off and to keep the connection sealed; the support and protection frame 3 provides support and protection for the beam guide 8 inside the first sleeve 1, preventing the beam guide 8 from bending and being squeezed during the operation; the lens outlet 5 is a constriction port that can fix and seal the second sleeve 2 and the endoscope 7.
