[0029] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, wherein the drawings form a part of the present application and are used to explain the principles of the present application, and are not intended to limit the scope of the present application.

[0030] Example 1

[0031] In one specific embodiment of the present application,Figure 1 、 Figure 2 and Figure 3 shows a foldable protective cover for laparoscope, including a main frame 1, a protective layer 2 and a sealing strip 3.

[0032] The structure of the main frame 1 is shown in Figure 1 、 Figure 2 . The main frame 1 includes two end faces 11, two side faces 12 and a top face 13. The two side faces 12 and the top face 13 are designed in an accordion style (i.e. telescopic design), each face is connected by hinges with multiple equal-width metal sheets 15, and adjacent metal sheets 15 can rotate relative to each other to achieve the unfolding or folding of the main frame 1. The folded state is shown in Figure 3 .

[0033] Referring to Figure 4 , both side edges of each metal sheet 15 are designed with grooves 16 for fixing the protective layer 2 (the red part in Figure 4 ), ensuring airtight and seamless combination. This design ensures that the protective layer will not fall off or shift in various use scenarios (such as bumps during equipment transportation, frequent operations during surgery, etc.), ensuring the protection effect.

[0034] The grooves 16 are strip-shaped grooves with moderate width and depth, the width is sufficient to accommodate the edge part of the protective layer 2, and the depth can ensure that the protective layer 2 is firmly embedded to prevent it from easily falling out. For example, the width of the groove 16 is 3-5 mm, and the depth is about 2-3 mm, and the specific size can be adjusted according to the thickness of the protective layer 2 and the required fixing strength.

[0035] The main frame 1 is a telescopic structure, and the two side faces 12 and the top face 13 can be folded (as shown in Figure 3 ) or unfolded (as shown in Figure 1 ). In the unfolded state, the size is 42×52×52cm, which can completely cover common laparoscope instruments and provide all-round protection; after folding, the size is 12×6×6cm, which is convenient for storage and carrying. When the equipment needs to be quickly transferred in a field hospital, it can be quickly folded to save space; when it is not used in the operating room of a daily hospital, it can also be easily stored.

[0036] The main frame 1 is made of 2219 aluminum alloy, which has excellent corrosion resistance, strength and toughness, and can withstand 300℃ high temperature. This material can maintain structural stability in harsh environments (such as high-temperature field environments, high-humidity coastal rescue scenarios, etc.), providing solid support for the protective cover.

[0037] The protective layer 2 is made of multi-layer composite material, including flame-retardant nylon and polytetrafluoroethylene (PTFE) coating. The flame-retardant nylon can effectively prevent the spread of fire when encountering a fire source, and the PTFE coating provides excellent waterproof performance, ensuring that the instrument is not damaged in a humid or water-splashed environment (such as a temporary operating room in flood rescue medical rescue). The protective layer 2 covers the outside of the main frame 1, and the joint is sealed with heat sealing technology to ensure waterproof performance.

[0038] The manufacturing steps of the protective layer 2 are as follows: first, lay the flame-retardant nylon material as the base layer evenly on a specific mold or workbench. Then, apply the PTFE coating uniformly to the surface of the flame-retardant nylon by spraying, brushing or dipping, etc. After the coating is applied, use a hot press or similar equipment to laminate the composite material. During the lamination process, appropriate temperature, pressure and time are applied to make the PTFE coating fully integrate with the flame-retardant nylon material, forming a tightly bonded composite structure. The temperature control should be able to make the PTFE coating melt and produce good adhesion with the flame-retardant nylon, without damaging the performance of the flame-retardant nylon; the pressure ensures that there are no bubbles or gaps between the coating and the base layer, and the coating is evenly attached; the time is adjusted according to the thickness of the material and the performance of the equipment to achieve the best composite effect.

[0039] The protective layer 2 is fixed to the outer surface of the metal sheet 15 by adhesive, and the two side edges of the protective layer 2 extend into the grooves 16 on both sides of the metal sheet 15.

[0040] After the multiple metal sheets 15 are assembled into a surface, a special heat sealing equipment can be used to apply certain temperature and pressure to the joint between the two adjacent protective layers 2, so that the molecules of the material at the joint diffuse and intermingle, forming a continuous and seamless whole.

[0041] The tightly bonded joint after heat sealing can effectively prevent small particles and liquids such as dust and water droplets from penetrating from the joint, ensuring that the waterproof and dustproof performance of the protective layer 2 meets high standards, providing reliable protection for the laparoscope instrument.

[0042] At the same time, the protective layer 2 becomes a continuous whole, enhancing the structural strength and stability of the protective layer 2. During daily use, folding and unfolding, it can better withstand external forces and is less likely to crack or break, prolonging the service life of the protective layer.

[0043] The adjacent protective layers 2 can also be bonded by special glue, which is compatible with the protective layer materials such as flame-retardant nylon and PTFE coating. This glue does not negatively affect the performance of the protective layer materials, such as not affecting the flame retardancy, waterproofness and corrosion resistance, while providing sufficient bonding force to ensure that the composite material is firmly connected at the joint.

[0044] This method can be used for some local repair of the protective layer 2 or as a supplement to the heat sealing technique in special cases. For example, when there is a small area of damage to the protective layer 2 that needs to be repaired, or when heat sealing is not convenient in some complex shape areas, special glue can be used for bonding.

[0045] The sealing strip 3 is arranged at the opening 14 of the protective cover, as shown in Figure 5 Figure 5 The middle yellow part is the sealing strip 3), which surrounds the edge of the entire opening 14.

[0046] When the protective cover is unfolded and covers the laparoscope instrument, the sealing strip 3 is exactly at the contact interface between the protective cover and the instrument, playing the role of sealing the gap between them, preventing harmful substances such as dust, liquid or flame from entering the inside of the protective cover from the opening, thereby protecting the internal laparoscope instrument. Whether in a conventional surgical environment or in a complex outdoor rescue scene, the sealing strip 3 can ensure that the protective cover and the instrument are tightly attached, preventing harmful substances such as dust, moisture and flame from entering. Whether the protective cover is in an unfolded use state or a folded storage state, the sealing strip 3 is always located at the edge of the opening 14 to ensure that it can maintain good sealing performance in different situations. When folded, the elasticity of the sealing strip 3 also allows it to adapt to the deformation of folding, without affecting its sealing function and service life.

[0047] The sealing strip 3 is made of silicone material with high elasticity, which has good ductility and high temperature resistance, ensuring the sealing effect in the folded state. When the device is frequently folded and unfolded (such as during multiple transfers of the device), it can still maintain good sealing to prevent dust and moisture from entering.

[0048] Using the sealing strip 3 ensures the sealing effect and adapts to different shapes and sizes of instruments. Whether it is a conventional shape laparoscope instrument or some specially designed new equipment, the sealing strip 3 can tightly adhere to ensure the protective effect.

[0049] The sealing strip 3 plays a key sealing role in the protective cover, and its use method is as follows:

[0050] Preparation before installation: Before installing the sealing strip 3, make sure that the main frame 1 of the protective cover and the surface of the instrument to be sealed are clean, dry, free of dust, oil stains and other impurities, so as not to affect the sealing effect of the sealing strip 3.

[0051] Installation process: In the folded state of the protective cover, install the sealing strip 3 along the edge of the opening 14 of the protective cover, so that it tightly adheres to the opening.

[0052] ​The protective cover is unfolded and covers the instrument to be sealed, and the sealing strip 3 is elongated in the process of unfolding the protective cover due to the elasticity of the sealing strip 3. After the protective cover covers the laparoscope instrument, the sealing strip 3 is retracted under the action of the elasticity of the sealing strip 3 and is tightly attached to the surface of the instrument. Due to the elasticity of the sealing strip 3, the sealing strip 3 can adapt to the irregular shape of the surface of the instrument and thus provide a good sealing effect at different positions. The sealing strip 3 is kept in close contact with the instrument without any gap or wrinkle at the entire edge of the opening 14 to prevent dust, water droplets or flames from entering the inside of the protective cover through the gap.

[0053] The foldable protective cover for a laparoscope of the utility model is unfolded to a proper size to cover the laparoscope instrument during use, and adjustment is made to ensure tight attachment without leakage risk. In a tense operation environment of a field hospital, medical staff can quickly install the protective cover in place to provide instant protection for the operation instrument. The protective cover is easily folded into a compact form for storage when not in use. After the rescue mission is completed, the protective cover can be conveniently stored for quick use next time.

[0054] Compared with the prior art, the foldable protective cover for a laparoscope provided in the embodiment has comprehensive protection performance, is flexible and portable, is durable and reliable, and is easy to operate.

[0055] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the utility model, and all the changes or replacements should be covered in the protection scope of the utility model.
