Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a disposable sterile drape for endoscopes. Background Technology

[0002] With the advancement of endoscopic technology, the range of endoscopic surgeries is constantly expanding, and the number of instruments used in endoscopic surgery is also increasing. Currently, the traditional method for using instruments is to first lay a sterile drape on the instrument cart, then place the endoscopic instruments on top of the sterile drape, and select the instruments as needed during the procedure.

[0003] However, the instruments used in endoscopic surgery are characterized by being long, thin, and slippery. Instruments such as biopsy forceps and electric snares include handles, slip rings, cables, and outer tubes, with an effective length of 1600mm-2300mm. Endoscopic instruments are extremely prone to springing off from the sterile drape and slipping onto the ground, rendering the instruments unusable and even causing injury to medical staff. Furthermore, different instruments can easily become entangled, making them very inconvenient to retrieve and seriously affecting the progress of the surgery.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a disposable sterile towel for endoscopy in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solution: a disposable sterile drape for endoscopes, comprising a sterile covering body, wherein a sterile instrument storage bag for placing medical devices is connected to the side of the sterile covering body, and the sterile instrument storage bag comprises: The rear panel is connected to the sterile covering body; The front piece connects with the rear piece to form a receiving cavity; The partition piece is provided in several sections, which are arranged along the depth direction of the receiving cavity and are connected to the rear piece at both ends and connected to the front piece at the middle position. To form an independent partition chamber between the rear and front pieces of the adjacent partition pieces.

[0007] The present invention is further configured such that: a gap is formed between the middle part of the partition piece and the rear piece, and the front piece passes through the gap and fits against the middle part of the partition piece.

[0008] The present invention is further configured such that: the front piece is provided with a plurality of folding areas, and in the initial state, the folding areas are located in the area that fits with the middle part of the partition piece.

[0009] The present invention is further configured such that the folding area is configured as an isosceles triangle structure, wherein the apex of the triangle points to the bottom of the receiving cavity.

[0010] The present invention is further configured such that: a plurality of extension limit marking lines for indicating the maximum unfolding range are sewn onto the front piece, each of the extension limit marking lines is sewn onto each folding area, and the two ends of the extension limit marking lines are respectively symmetrically arranged on both sides of the central axis of the folding area passing through the sharp corner position, for indicating the extreme position when the folding area unfolds along the base direction of the isosceles triangle structure.

[0011] The present invention is further configured such that: the two ends of the side of the sterile covering body away from the sterile instrument storage bag are sewn together with a main body fixing strap, and the end of the main body fixing strap away from the sterile covering body is movable.

[0012] The present invention is further configured such that: the two ends of the back piece near the sterile covering body are sewn together with a back fixing strap, and the end of the back fixing strap away from the back piece is movable.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Firstly, the independent compartments formed by the partitions enable the positioning and storage of instruments, creating a precise retrieval mechanism. This prevents instruments from slipping or becoming tangled, which would affect retrieval. At the same time, the independent compartment design reduces rummaging time, and the extended limit lines visually display the space utilization rate. Furthermore, the accordion-style "sliding layer" allows nurses to adjust the sterile space with one hand, further shortening the retrieval time. Secondly, the honeycomb hot-pressed structure of the rear panel and the partition increases torsional strength by 30%, allowing it to withstand 15kg of instrument pressure without deformation. A 0.3mm thick support strip ensures the partition has a bending strength of 8N·m, guaranteeing the instruments won't tip over when stored vertically. The gaps created by the partition disperse localized pressure to the frame, and tear strength tests show a 60% improvement over traditional designs. Third, the vertical height of the isosceles triangular folding area increases by 20-30% after unfolding, and the high elasticity of the front piece achieves a 30% volume expansion. The extended limit marking line generates a 2.5N reverse pull when the maximum unfolding range is reached to prevent excessive stretching. Fourth, the rear fixing strap design ensures even weight distribution, reduces swaying by 80% when the instrument cart moves, prevents the instruments from slipping, and achieves optimized instrument protection.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Example

[0017] Disposable sterile drapes for endoscopy, such as Figure 1 As shown, the device includes a sterile covering body 1, with a sterile instrument storage bag 2 for placing medical devices connected to the side of the sterile covering body 1. The sterile instrument storage bag 2 includes a rear piece 3 connected to the sterile covering body 1, a front piece 4 connected to the rear piece 3 to form a receiving cavity, and several partition pieces 5. The partition pieces 5 are arranged along the depth direction of the receiving cavity, and their ends are connected to the rear piece 3, while the middle part of the partition piece 5 is connected to the front piece 4. This divides the receiving cavity between the rear piece 3 and the front piece 4 between adjacent partition pieces 5 into several independent compartments. The independent compartments formed by the partition pieces 5 can guide the precise placement of instruments, reducing the average time for nurses to pick up and place instruments by 15-20 seconds, optimizing instrument retrieval and placement, improving operational efficiency, and better avoiding the risk of instruments slipping in traditional methods.

[0018] The back piece 3 and the front piece 4 are covered with an EPTFE (polytetrafluoroethylene) membrane on their adjacent surfaces. The EPTFE membrane has a microporous structure that enables it to be waterproof and breathable. It is highly weather-resistant and corrosion-resistant, and is widely used in medical protective clothing. It is suitable for high-requirement scenarios, thus giving the sterile instrument storage bag 2 waterproof performance while also meeting the usage requirements of the medical industry.

[0019] A gap is formed between the middle of the partition piece 5 and the rear piece 3. The front piece 4 passes through this gap and fits against the middle of the partition piece 5, thus forming a fixed-moving combination design. The rigid support frame is constructed through the fixed connection between the rear piece 3 and the partition piece 5. Even if the front piece 4 is displaced by the pressure of the machine, the integrity of the frame structure can still ensure the overall stability.

[0020] The gap design allows the front panel 4 to distribute pressure onto the frame formed by the rear panel 3 and the partition panel 5 when under stress, preventing localized stress concentration that could lead to tearing. Furthermore, the rear panel 3 and the partition panel 5 utilize a honeycomb hot-pressed structure instead of a planar connection, increasing torsional strength by 30%, thereby enhancing the frame's ability to withstand pressure. Figure 2 As shown, a 0.3mm thick PE support strip 10 is embedded in the partition 5. The PE support strip 10 enhances the structural strength of the partition 5 and further improves the load-bearing capacity of the frame.

[0021] Furthermore, the design of the front panel 4 passing through the gap essentially creates a "sliding layer". When it is necessary to expand the sterile space, simply pull the front panel 4 outward to freely adjust the volume of the sterile space, just like stretching an accordion bellows.

[0022] The back panel 3 is made of nonwoven or coated nonwoven fabric to ensure sterility and is sterilized with ethylene oxide, making it safe and effective.

[0023] The anterior panel 4 is made of medical-grade silicone-coated composite fabric that meets ISO 10993 biocompatibility standards, enhancing durability and sealing. Furthermore, a heat-sealing process is added at the connection between the posterior panel 3 and the anterior panel 4 to eliminate seams. Based on the elongation of the medical-grade high-elasticity silicone-coated fabric, this fixed-movable combination design expands the sterile space by 30% compared to traditional fixed-separation designs, allowing for more endoscopic accessories such as biopsy forceps and snares, reducing the number of instrument changes during surgery.

[0024] Furthermore, by utilizing the independent sterile space formed by the partition piece 5, combined with the elastic seal of the front piece 4, it is equivalent to creating multiple "sterile isolation chambers" inside the sterile bag, achieving an upgrade in physical isolation. Even if a sterile space is accidentally contaminated, the shrinkage characteristics of the front piece 4 can quickly isolate the contaminated area, prevent its spread, and block the contamination path.

[0025] At the same time, such as Figure 1 As shown, the front piece 4 is provided with several folding areas 6. The folding structure of the folding areas 6 provides a basis for the expansion of sterile space, ensuring storage and transportation needs. In the initial state, that is, before instruments are placed, the folding areas 6 are located in the area that fits with the middle of the partition piece 5. The partition piece 5 restricts the volume of the folding areas 6, avoiding the problem of structural bulkiness caused by the folding areas 6.

[0026] like Figure 1 As shown, the folding area 6 is designed as an isosceles triangle with the apex pointing towards the bottom of the receiving cavity. When the inverted triangular folding area 6 is unfolded, the apex acts as a fulcrum, causing the two wings to expand outward, forming a three-dimensional structure similar to a "tent". Compared with the flat folding design, the inverted triangular structure can increase the vertical height of the sterile space by 20-30%, achieving better expansion of the vertical space. This allows for the accommodation of more long-handled instruments such as endoscopic biopsy forceps, reducing the number of instrument changes during the procedure.

[0027] Furthermore, the sharp corner position will restrict the partition plate 5 and prevent it from expanding outward, thus forming a good restraint effect, ensuring that the instrument fits on the rear plate 3, further reducing the risk of tipping over, and the inverted triangular structure has about 40% higher shear strength than the traditional rectangular folding area 6.

[0028] At the same time, such as Figure 1 As shown, the front piece 4 is sewn with several extension limit marking lines 9 to indicate the maximum unfolding range. Each extension limit marking line 9 is sewn onto each folded area 6, and the two ends of the extension limit marking lines 9 are symmetrically positioned on both sides of the central axis passing through the sharp corner of the folded area 6. Thus, when the inverted triangular folded area 6 is unfolded, the positions of the two ends of the extension limit marking lines 9 move away from each other, causing the extension limit marking lines 9 to change from a relaxed state to a taut state. When the extension limit marking lines 9 are fully taut, the folded area 6 reaches its maximum unfolding range, thereby avoiding excessive stretching and ensuring usability. At the same time, the extension limit marking lines 9 generate reverse constraint tension to control the unfolding range of the folded area 6.

[0029] like Figure 1 As shown, the two ends of the side of the sterile covering body 1 away from the sterile instrument storage bag 2 are sewn together with a main body fixing strap 7. The end of the main body fixing strap 7 away from the sterile covering body 1 is movable. The main body fixing strap 7 can fix one side of the sterile covering body 1, thereby preventing the sterile covering body 1 from sliding after the sterile instrument storage bag 2 is placed.

[0030] like Figure 1 As shown, the two ends of the back piece 3 near the sterile covering body 1 are sewn together with a back fixing strap 8. The end of the back fixing strap 8 away from the back piece 3 is movable and connected to the instrument cart through the back fixing strap 8 to achieve a lifting effect on the back piece 3. This prevents the sterile instrument storage bag 2 from pulling the sterile covering body 1 down together after the instrument is placed. In addition, the back fixing strap 8 bears the weight of the instrument and reduces the tension on the connection between the sterile covering body 1 and the sterile instrument storage bag 2.

[0031] Working principle: The nurse first lays out the sterile covering body 1 on the instrument cart, and then uses the main body fixing strap 7 and the rear fixing strap 8 to tie it to the instrument cart to fix its position. Then, the sterile instrument storage bag 2 is flipped down so that the sterile instrument storage bag 2 is located on the side of the instrument cart. Then, the instruments can be placed into the independent compartment as needed. At the same time, before placement, the nurse can pull the front panel 4 outward according to the size of the instrument, so that the front panel 4 located in other areas can move accordingly, thereby expanding the volume and achieving a better placement effect.

[0032] Furthermore, when placing instruments in sequence, the folding area 6 will be stretched open by the instruments, thereby pulling the extension limit indicator line 9 from a relaxed state to a taut state. By observing the extension limit indicator line 9, the current extension state can be determined. When the extension limit indicator line 9 is in a taut state, the placement method of the instruments needs to be adjusted to avoid further enlargement of the independent compartment space.
