Description

Technical Field

[0001] The invention relates to a surgical sheet, and in particular to a surgical sheet fluid drainage and collection device. Background Art

[0002] Arthroscopic surgery is a minimally invasive surgical method that is widely used in orthopedic clinical practice. In knee arthroscopy, the patient's affected limb is usually required to extend from the window of the surgical sheet so that the doctor can perform the operation. The standard surgical position requires the patient's knee joint to be internally rotated and flexed 90 degrees at the same time. This position is convenient for the surgeon to perform the operation and can fully expose the surgical area.

[0003] During the operation, the doctor needs to establish a surgical approach in the lateral joint space of the knee. Specifically, an incision is made between the posterior edge of the iliotibial band and the anterior edge of the biceps femoris at the proximal part of the fibula head. However, during the operation, it is necessary to continuously use saline and other flushing fluids to flush the joint cavity to keep the surgical field clear. These flushing fluids are mixed with the accumulated fluid in the joint cavity and will continue to flow out from the incision. Because the affected limb is located on the surgical sheet, these mixed fluids will flow uncontrollably along the surface of the surgical sheet and eventually flow onto the floor of the operating room.

[0004] This situation brings about many adverse effects. First, a large amount of accumulated fluid and flushing fluid will make the floor of the operating room slippery, increasing the risk of medical staff slipping during surgery. Second, these fluids may contain biological contaminants such as blood and tissue debris, which will cause environmental pollution and increase the risk of cross-infection when flowing directly to the ground. In addition, the flow of liquid will also wet the surgical shoes and shoe covers of medical staff, which will not only affect comfort, but may also cause medical staff to come into direct contact with contaminants.

[0048] The following describes in detail the fluid drainage and collection device for the surgical sheet 30 according to an embodiment of the present invention with reference to the accompanying drawings.

[0049] Reference Figures 1 to 4 As shown, the fluid diversion and collection device for a surgical sheet 30 provided according to an embodiment of the present invention includes a waterproof membrane 10 and a water retaining and collecting structure 20 .

[0050] Specifically, the waterproof film 10 is attached to the surface of the surgical sheet 30, and the upper end of the waterproof film 10 is adjacent to the window H30 on the surgical sheet 30. The waterproof film 10 can be made of medical grade waterproof material, such as PVC, PP material, with a thickness of 0.2-0.5 mm, and has good waterproofness and certain toughness. A certain distance, such as 10-15 mm, is reserved between the upper end of the waterproof film 10 and the edge of the window H30 of the surgical sheet 30 to prevent interference with the surgical operation area.

[0051] The water retaining and collecting structure 20 includes two retaining bars 201 and a collecting bucket 202 . The two retaining bars 201 are arranged on both sides of the waterproof membrane 10 in the width direction. The collecting bucket 202 is arranged at the lower end of the waterproof membrane 10 and connected to the two retaining bars 201 .

[0052] The two baffles 201 in the water-retaining and collecting structure 20 can be made of the same material as the waterproof membrane 10 and formed in one piece, or made of a different material from the waterproof membrane 10, for example, made of medical-grade soft silicone material, with a width of 3-5 mm and a height of 12-18 mm. The function of the baffle 201 is to prevent the accumulated fluid from flowing out to the ground on both sides of the surgical sheet 30 during surgery. The collecting hopper 202 is arranged at the lower end of the waterproof membrane 10, and can be manufactured by an integrated injection molding process, and is formed as a whole with the baffle 201. The upper opening width of the collecting hopper 202 matches the distance between the two baffles 201, and a liquid outlet 2021 is provided at the bottom thereof. Under the water-retaining effect of the baffle 201, it is ensured that the accumulated fluid can be gathered and flow to the collecting hopper 202 below, and the accumulated fluid flowing on the waterproof membrane 10 is collected by the collecting hopper 202.

[0053] A guide structure is arranged on the waterproof membrane 10, and the guide structure is located between the two baffles 201, and the guide structure is configured to slow down the flow rate of the accumulated liquid on the waterproof membrane 10 and guide the accumulated liquid to the collecting bucket 202. When the liquid accumulates on the waterproof membrane 10 too quickly, the accumulated liquid may splash around, causing pollution to the surrounding environment. Therefore, a guide structure is provided on the waterproof membrane 10, and these guide structures are arranged between the two baffles 201. When the accumulated liquid on the waterproof membrane 10 flows through the collecting bucket 202, it first passes through these guide structures. The guide structure can slow down the flow rate of the accumulated liquid and guide it to the collecting bucket 202 according to a predetermined path. In this way, through the deceleration and diversion effect of the guide structure, the problem of liquid accumulation caused by the accumulated liquid flowing too quickly on the waterproof membrane 10 can be prevented.

[0054] According to the surgical sheet 30 effusion diversion and collection device provided by the embodiment of the present invention, a waterproof film 10 is attached to the surface of the surgical sheet 30, and a water retaining and collecting structure 20 composed of a baffle 201 and a collecting bucket 202 is arranged on the waterproof film 10, and a diversion structure arranged between the two baffles 201 is formed to form an effusion diversion and collection device. The waterproof film 10 can block the effusion from penetrating into the surgical sheet 30 to prevent the surgical sheet 30 from being soaked; the baffles 201 on both sides can limit the lateral diffusion of the effusion to prevent the effusion from overflowing the surgical area; the diversion structure slows down the flow rate of the effusion to avoid splashing when the effusion flows at high speed, and guides the effusion to flow to the collecting bucket 202 along a preset path, and finally realizes the directional collection of the effusion. This structural design can not only effectively prevent the floor of the operating room from being wetted by the effusion and becoming slippery, reducing the risk of medical staff slipping, but also prevent the effusion containing biological contaminants from polluting the environment and reducing the risk of cross infection. At the same time, it also creates a drier and safer surgical environment for medical staff, improves the comfort and safety of surgical operations, and has significant clinical practical value.

[0055] In one embodiment of the present invention, a drainage tube and a waste liquid bag are further included, one end of the drainage tube is connected to the bottom of the collection bucket 202, and the other end of the drainage tube is connected to the waste liquid bag, so that the accumulated liquid is collected by the waste liquid bag. Exemplarily, a liquid outlet 2021 is provided at the bottom of the collection bucket 202, and the liquid outlet 2021 is connected to the waste liquid bag through the drainage tube.

[0056] Preferably, a drain valve is provided at the bottom of the waste liquid bag, so that the waste liquid bag can be emptied when needed. A scale line is provided on the front of the waste liquid bag for observing the amount of waste liquid collected. To ensure that the waste liquid can flow smoothly into the waste liquid bag, in actual use, the waste liquid bag is hung at a lower position of the operating table, and gravity is used to allow the accumulated liquid to flow in naturally.

[0057] This embodiment provides a diversion tube and a waste fluid bag, and ensures that the accumulated fluid can flow stably into the waste fluid bag through the principle of gravity flow, thereby realizing closed-loop management of surgical fluid accumulation.

[0058] In one embodiment of the present invention, the flow guiding structure includes a plurality of groups of flow guiding lines, and the plurality of groups of flow guiding lines are arranged at intervals along the up-down direction.

[0059] Each group of the guide lines includes a plurality of stripes 203 protruding from the outer surface of the waterproof membrane 10 . The plurality of stripes 203 are arranged at intervals along the width direction of the waterproof membrane 10 , and a guide gap H201 is formed between two adjacent stripes 203 .

[0060] Specifically, the stripe portion 203 is made of the same material as the waterproof membrane 10 and is manufactured in an integrated manner through an injection molding process to ensure the connection strength between the stripe portion 203 and the waterproof membrane 10. The cross-sectional shape of each stripe portion 203 is a rectangular, trapezoidal, etc., with a width of 1.5-3.5 mm and a height of 2.0-5 mm. In each group of guide ribs, the guide gap H201 between two adjacent stripes 203 has a width of 5-10 mm. The setting of the guide gap H201 can slow down the flow rate of the effluent without causing stagnation of the effluent.

[0061] This embodiment achieves precise control of the flow of effluent by providing guide lines on the surface of the waterproof membrane 10. The guide gaps H201 between the lines 203 ensure smooth flow of effluent; the multi-level guide line design can not only effectively slow down the flow rate of effluent and prevent splashing, but also achieve uniform distribution of effluent by changing the flow direction of the liquid, and finally ensure that the effluent can be stably introduced into the collection bucket 202.

[0062] Preferably, each group of guide lines is arranged in a staggered manner. Specifically, the stripe portions 203 in the two adjacent groups of guide lines are staggered in the horizontal direction, and the staggered distance is 1 / 2 of the length of the stripe portion 203. This staggered arrangement can ensure that the accumulated liquid changes direction multiple times during the flow process, significantly reducing the flow rate. At the same time, the staggered arrangement can also prevent the formation of a channel for the liquid to fall directly, thereby improving the deceleration effect.

[0063] In one embodiment of the present invention, the stripe portion 203 in each group of the guide stripes is formed into an inclined straight line or an "S" shape. For example, the length direction of the stripe portion 203 forms an angle of 45-75 degrees with the width direction of the waterproof membrane 10.

[0064] In this embodiment, the purpose of the inclined stripe portion is to extend the actual flow path of the effluent within the limited area of ​​the waterproof membrane 10. When the effluent flows through the inclined stripe portion 203, the travel path is elongated, and when the fluid flows in a zigzag manner, a large flow resistance will be generated, thereby naturally reducing the flow rate. Therefore, through this inclined linear or "S"-shaped curve design, the effect of slowing down the flow rate of the effluent can be greatly improved without increasing the number of stripe portions 203.

[0065] Advantageously, the inclined directions of the stripes 203 in the two adjacent groups of guide lines are opposite. In order to further enhance the control ability of the guide structure over the flow of the effluent, in this example, in the two adjacent upper and lower groups of guide lines, although the stripes 203 inside each group maintain a uniform inclined direction, the stripes 203 between the two adjacent groups are designed to have opposite inclined directions. With this inclined reverse design of the upper and lower adjacent groups, when the effluent flows from top to bottom through the first group of inclined stripes 203, it will first flow to one side of the horizontal direction, and then when it reaches the next group, it will be forced to change to flow to the other side of the horizontal direction opposite to the previous group. This repeated alternating disturbance greatly increases the number of turns and twists of the effluent during the entire flow process, which not only further extends the actual flow path, but also generates more turbulence, greatly increasing the flow resistance.

[0066] Reference Figure 4 As shown, in some embodiments of the present invention, the fluid diversion and collection device of the surgical sheet 30 further includes a water absorbing layer 11 , and the water absorbing layer 11 is disposed on the inner surface of the waterproof membrane 10 .

[0067] The waterproof membrane 10 is provided with a plurality of water-permeable holes H202, which are distributed in a matrix on the waterproof membrane 10 and located in the corresponding flow-guiding gaps H201, so that part of the accumulated liquid flowing through the waterproof membrane 10 passes through the water-permeable holes H202 and is absorbed by the water-absorbing layer 11. When the accumulated liquid flows along the flow-guiding pattern, it can just pass through these water-permeable holes H202, and part of the accumulated liquid penetrates into the waterproof membrane 10 through the water-permeable holes H202. The size of the water-permeable holes H202 is usually controlled in the range of 2-3 mm.

[0068] In this embodiment, the water-absorbing layer 11 on the inner side of the waterproof membrane 10 cooperates with the flow-guiding structure on the outer surface to form a double-layer structure for guiding and absorbing the accumulated liquid. The outer layer of the flow-guiding structure controls the flow rate of the accumulated liquid and guides it to flow smoothly to the collection bucket 202 through the design of the ribbed portion 203 and the flow-guiding gap H201. At the same time, part of the accumulated liquid penetrates into the interior through the permeable holes H202 and is quickly absorbed by the water-absorbing layer 11 with a high liquid absorption rate. This dual action mechanism ensures that most of the accumulated liquid is collected smoothly, avoids disordered splashing and residue, and further reduces the risk of pollution.

[0069] In one embodiment of the present invention, the water-absorbing layer 11 includes an upper water-absorbing layer 11 and a lower water-absorbing layer 11, the upper water-absorbing layer 11 is made of hydrophilic non-woven fabric, and the lower water-absorbing layer 11 is made of polymer water-absorbing material; the aperture of the multiple water-permeable holes H202 gradually increases from top to bottom.

[0070] In this embodiment, the water-absorbing layer 11 is designed to have an upper and lower two-layer structure, each made of different materials. The upper water-absorbing layer 11 is made of a hydrophilic non-woven material, which mainly plays the role of rapid penetration and preliminary absorption. The lower water-absorbing layer 11 uses a polymer water-absorbing material, such as a super-absorbent polymer hydrogel, which has a higher continuous liquid absorption capacity than non-woven fabrics. The combination of the upper and lower layers of water-absorbing materials gives full play to their respective advantages and realizes the combination of fast absorption and high absorption. When the accumulated liquid penetrates into the waterproof membrane 10 through the permeable hole H202, it is firstly quickly absorbed by the highly permeable hydrophilic non-woven fabric to avoid liquid accumulation and retention. Subsequently, the liquid in the non-woven fabric is continuously absorbed by the polymer hydrogel with high water absorption capacity in the lower layer through capillary action, so that the liquid absorption of the entire water-absorbing layer 11 is greatly improved. This design of fast absorption first and high absorption later ensures that the accumulated liquid can be efficiently transferred from the outer layer of the waterproof membrane 10 to the internal absorption channel, realizing efficient up and down transfer.

[0071] In one embodiment of the present invention, the periphery of the waterproof membrane 10 is sealed to the surface of the surgical sheet 30 by ultrasonic heat-sealing process, or the periphery of the waterproof membrane 10 is bonded to the surface of the surgical sheet 30 by a self-adhesive layer. By ultrasonic heat-sealing process, a surgical sheet 30 with an integrated structure can be manufactured, and the fluid diversion and collection device of the surgical sheet 30 is integrated on the waterproof membrane 10. By using the self-adhesive layer bonding method, it can be used as an independent accessory, which is convenient to configure according to needs.

[0072] In one embodiment of the present invention, the surface of the stripe portion 203 is covered with a hydrophobic coating, and the surface of the flow-guiding gap H201 is covered with a hydrophilic coating.

[0073] In this embodiment, two different surface coatings with different properties, hydrophobic and hydrophilic, are used in different areas of the surface of the waterproof membrane 10. Specifically, the surface of the stripe portion 203 in each group of guide lines is covered with a hydrophobic coating with good hydrophobic properties, such as a fluorocarbon coating. The guide gap H201 area between the stripe portions 203 is covered with a hydrophilic coating with excellent hydrophilic properties, such as a coating made of hydrophilic polymer materials such as polyvinyl alcohol. This partitioning arrangement of hydrophobic and hydrophilic areas makes full use of the difference in affinity between the two coating materials, and further optimizes the guiding effect of the guide structure on the flow of liquid accumulation. Since the surface of the stripe portion 203 is covered with a hydrophobic coating, the stripe portion has a strong repulsive effect on the liquid, and the liquid will automatically avoid it when flowing through these stripe portions. On the contrary, the guide gap H201 area is covered with a hydrophilic coating, which has a strong attraction and affinity for the liquid, so the liquid will actively move closer and penetrate into the area when flowing through the gap.

[0074] Preferably, the width between the upper ends of the two baffles 201 gradually decreases from top to bottom. By designing a geometric shape in which the width between the upper ends of two adjacent baffles 201 gradually decreases from top to bottom, the wider upper area provides space for flow, which is conducive to more accumulated liquid being collected by the upper area. The narrowed lower area can concentrate the flow and facilitate its drainage to the collection bucket 202.
