Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a disposable sterile endoscope sleeve. Background Technology

[0002] Technological advancements have made it possible to perform surgery through smaller incisions. This results in less tissue damage compared to traditional surgery. Through a keyhole-sized incision, surgeons can insert tiny light sources, cameras, and surgical instruments. The surgeon then uses images transmitted to a monitor to guide the manipulation of these instruments, a process known as laparoscopic surgery.

[0003] However, the cameras used in laparoscopic surgery need to be kept sterile. Clinically, to save costs, reduce damage to the cameras and cables during the sterilization process, and extend their lifespan, sterile laparoscopic sleeves are often used. Traditional sterile laparoscopic sleeves require surgeons to strap on the lenses, stretch them open, and string them together on the operating table. This process is cumbersome, increases surgical preparation time, and can cause leakage problems in arthroscopic and UBE surgeries.

[0004] How to provide a waterproof and easy-to-use disposable sterile endoscope sleeve is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0015] Beneficial effects:

[0016] This utility model provides a disposable sterile endoscope sleeve. When not in use, the pull ring on the cylindrical sleeve rolls along the sleeve's body towards one end of the rubber ring. The sleeve body rolls up with the pull ring until it reaches the rubber ring. Simultaneously, the hanging rope is arranged parallel to the cylindrical sleeve and is rolled inside the sleeve as it rolls up. Since the length of the hanging rope is not less than the length of the cylindrical sleeve, a portion of the rope remains outside the rolled-up sleeve. When protection of the endoscope is needed, the rubber ring is first placed over the endoscope lens, with the pull ring and the sleeve body positioned on one side of the endoscope equipment and cables. The operator simultaneously pulls on a portion of the extended hanging ropes towards the endoscope cables. Rubber rings engage with the endoscope lens. As the ropes are pulled, the rolled-up cylindrical sleeve flips outwards, continuously rolling until the entire sleeve is exposed. At this point, the sleeve is positioned over the endoscope cables, effectively protecting both the endoscope's handle and the cables. This device is simple in structure and easy to operate; simply pull the ropes. The cylindrical sleeve and rubber rings provide protection and isolation for the endoscope equipment and cables, reducing damage to the camera and cables during sterilization and preventing liquid ingress.

Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification are within the protection scope of this utility model.

[0028] Furthermore, in the embodiments of this specification, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present.

[0029] Please see Figure 1-3 This embodiment provides a disposable sterile endoscope sleeve, which includes: a cylindrical sleeve 1, the diameter of one end of the cylindrical sleeve 1 being adapted to the size of the endoscope camera; a rubber ring 2, the diameter of the rubber ring 2 being adapted to the diameter of one end of the cylindrical sleeve 1, and the rubber ring 2 being sleeved on one end of the cylindrical sleeve 1; a pull ring 3, the diameter of the pull ring 3 being adapted to the diameter of the other end of the cylindrical sleeve 1, and the pull ring 3 being sleeved on the other end of the cylindrical sleeve 1; and several hanging ropes 4, the length of the hanging ropes 4 being not less than the length of the cylindrical sleeve 1, and the several hanging ropes 4 being evenly spaced on the pull ring 3.

[0030] Specifically, when not in use, the pull ring 3 on the cylindrical sleeve 1 of the endoscope rolls along the body of the sleeve 1 towards one end of the rubber ring 2. The body of the sleeve 1 rolls up with the pull ring 3 until it reaches the rubber ring 2. At the same time, the hanging rope 4 is also arranged parallel to the cylindrical sleeve 1 and is rolled inside the sleeve 1 as it rolls up. The length of the hanging rope 4 is not less than the length of the cylindrical sleeve 1, so a section of the hanging rope 4 is still outside the rolled-up cylindrical sleeve 1. When protection of the endoscope is needed, the rubber ring 2 is first placed on the endoscope lens, with the pull ring 3 and the body of the cylindrical sleeve 1 located on one side of the endoscope equipment and cables. Medical personnel simultaneously pull on the rubber ring 2. Several hanging ropes 4 extend outwards and are pulled towards the endoscope cable. The rubber ring 2 is secured to the endoscope lens. When the hanging ropes 4 are pulled, the rolled-up cylindrical sleeve 1 flips outwards along with the hanging ropes 4, and the pull ring 3 rolls continuously until the pull ring 3 is fully exposed and the cylindrical sleeve 1 is also fully exposed. At this time, the pull ring 3 is located at the endoscope cable, and the cylindrical sleeve 1 completes the complete wrapping and protection of the endoscope's handle and cable section. The device has a simple structure and is easy to operate. Simply pull the hanging ropes 4. The cylindrical sleeve 1 and rubber ring 2 complete the protection and isolation of the endoscope equipment and cable, reducing damage to the camera and cable during the disinfection and sterilization process and preventing liquid seepage.

[0031] In some possible implementations, the cylindrical sleeve 1 includes a winding section 11 and a lens sleeve section 12. Both the winding section 11 and the lens sleeve section 12 are frustoconical. The bottom diameters of the winding section 11 and the lens sleeve section 12 are the same. The bottom end of the winding section 11 is connected to the bottom end of the lens sleeve section 12. A rubber ring 2 is sleeved on the top end of the lens sleeve section 12, and a pull ring 3 is sleeved on the top end of the winding section 11.

[0032] Specifically, the bottom diameter of the frustum is larger than the top diameter. The cylindrical sleeve 1 is divided into a winding section 11 and a lens sleeve section 12. The winding section 11 needs to be rolled up with the pull ring 3. As the pull ring 3 rolls up continuously, the cylindrical sleeve 1 on the pull ring 3 becomes thicker and the diameter of the pull ring 3 and the cylindrical sleeve 1 on the pull ring 3 increases. The cylindrical sleeve 1 that is far away from the pull ring 3 needs to be continuously rolled up on the cylindrical sleeve 1 on the pull ring 3. Therefore, the cylindrical sleeve 1 that is farther away from the pull ring 3 will be stretched wider. When the winding section 11 is frustum-shaped, the end with the smaller diameter of the frustum is connected to the pull ring 3, and the end with the larger diameter of the frustum is far away from the pull ring 3. When the pull ring 3 drives the cylindrical sleeve 1 to roll up, the winding section 11 of the cylindrical sleeve 1 will not be stretched open due to the increasing diameter of the cylindrical sleeve 1 on the pull ring 3, resulting in damage. The lens sleeve section 12 is relatively short and does not need to be rolled up, making it fit more closely to the head of the endoscope device.

[0033] In some possible implementations, there are two hanging ropes 4, both of which are longer than twice the length of the tubular sleeve 1. The two ends of one hanging rope 4 are installed at a distance on one side of the pull ring 3, and the two ends of the other hanging rope 4 are installed at a distance on the other side of the pull ring 3.

[0034] Specifically, two hanging ropes 4 are located on both sides of the pull ring 3. Both ends of each hanging rope 4 are connected to the pull ring 3. The four ends of the two hanging ropes 4 are evenly distributed on the pull ring 3. The middle of each hanging rope 4 extends to one end of the rubber ring 2 of the tubular sleeve 1. When the tubular sleeve 1 is rolled up, the middle of each hanging rope 4 is located outside the rolled-up ring of the tubular sleeve 1. When in use, medical staff pull the middle of the two hanging ropes 4 at the same time, and the four sections of the two hanging ropes 4 simultaneously unfold the tubular sleeve 1, making the unfolding of the tubular sleeve 1 more uniform.

[0035] In some possible implementations, a pull rod 41 is provided in the middle of the hanging rope 4.

[0036] Specifically, when medical staff pull the hanging rope 4, they can pull it through the lever 41, which makes the lever 41 more convenient to use.

[0037] In some possible implementations, the cross-section of each hanging rope 4 is flat.

[0038] Specifically, the hanging rope 4 has a flat cross-section, and when the tubular sleeve 1 is rolled up, the flat surface is in close contact with the tubular sleeve 1. The hanging rope 4 will not protrude too much inside the tubular sleeve 1, causing the rolled-up tubular sleeve 1 to be uneven, and thus the tubular sleeve 1 to wrinkle.

[0039] In some possible implementations, the pull ring 3 is made of a rigid material, and the rubber ring 2 is made of medical-grade rubber. Adhesive is applied to the rubber ring 2.

[0040] Specifically, when the pull ring 3 is made of a rigid material, the cylindrical sleeve 1 will not deform due to pressure when rolled onto the pull ring 3. The rubber ring 2 needs to be tightly attached to the endoscope equipment. The rubber material is relatively soft and will not cause damage to the equipment. The rubber material has good elasticity, which makes it easy for the rubber ring to pass through and stick to the lens when using this protective sleeve. At the same time, when the rubber ring 2 is tightly attached to the lens of the endoscope equipment, it is bonded to the lens with adhesive, which further increases the tightness of the connection between the rubber ring 2 and the lens of the endoscope equipment. While preventing the rubber ring 2 from shifting, it can further prevent water from seeping into the endoscope equipment.

[0041] In some possible implementations, the diameter of the rubber ring 2 is 1 cm, and the diameter of the other end of the cylindrical sleeve 1 is 10 cm. The cylindrical sleeve 1 is made of medical-grade polypropylene.

[0042] Specifically, medical-grade polypropylene has good chemical stability and will not produce chemical reactions during the disinfection and sterilization process. It is also not easily damaged. The cylindrical sleeve 1 needs to pass through the endoscope equipment and cables, etc. A 10cm diameter ensures the protection of its passage. The endoscope needs to pass through the rubber ring 2 and restrict the entire endoscope equipment within the rubber ring 2. A 1cm rubber ring 2 is more suitable.
