Description

Technical Field

[0001] This invention relates to the field of surgical aids, and more particularly to a surgical incision protection device for thoracic surgery patients. Background Technology

[0002] Thoracic surgery incision protection devices are medical devices used to protect thoracic surgical incisions and promote wound healing. They are widely used in thoracic surgery and can effectively prevent incision tissue from being contaminated by surrounding organs and tissues, reduce the risk of infection, and prevent excessive traction and compression of the incision, thus helping to maintain the integrity of the incision and providing a clear view for surgical procedures.

[0003] When performing incision surgery with the aid of incision protection devices, instruments used to remove diseased tissue, enter the body for other operations, or administer medications all need to pass through a channel in the protection device. This increases the risk of cross-infection within the channel, leading to a decrease in the practicality of the incision protection device. Summary of the Invention

[0004] The purpose of this invention is to address the problem that when using instruments to remove diseased tissue, perform other operations inside the body, or administer drugs, the surgical incision protection device needs to be accessed and exited through a channel of the protective device, which increases the risk of cross-infection within the channel and reduces the practicality of the incision protection device. Therefore, this invention proposes a surgical incision protection device for thoracic surgery patients.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a surgical incision protection device for thoracic surgery patients, comprising a top ring with a circular hollow structure, a thin wall coaxially fixedly connected to the bottom end of the top ring along its axial direction, the thin wall being a flexible transparent membrane structure that can be rolled up or folded down along its own axial direction (e.g., rolled up and wrapped around the outer peripheral wall of the top ring), a soft ring coaxially fixedly connected to the bottom end of the thin wall along the same axis, the soft ring being made of elastic silicone material that can undergo radial contraction deformation under external pressure (e.g., shrinking from a circle to an ellipse) to adapt to surgical incisions of different sizes, the top ring and the compression ring described below both having the characteristics of being manually shaped and maintaining their shape after deformation (e.g., being fixed into an arc shape, semi-circle, etc. after being bent by external force), an auxiliary structure is fixedly provided inside the thin wall along its radial direction (i.e., perpendicular to the axis), the auxiliary structure being used to separate the internal space of the thin wall, reduce cross-infection, and improve the overall stability of the device.

[0006] Preferably, the auxiliary structure includes a separator membrane, two sheaths, and a connecting tube. The separator membrane is a flexible medical film, completely fixed to the inner wall of the thin-walled structure radially (e.g., extending from one edge to the other), dividing the cylindrical cavity inside the thin-walled structure into two independent semi-cylindrical channels (for different purposes such as surgical instruments and drug delivery). Both sheaths are hollow tubular structures, and the connecting tube is a solid rod-like structure. Both ends of the connecting tube are inserted from one end of each of the two sheaths, forming a retractable annular support assembly of sheath-connecting tube-sheath (the entire annular structure can be adjusted when the connecting tube slides along the axial direction of the sheath). The diameter of the component), the sleeve and connecting tube are both made of modified medical-grade polypropylene reinforced hard plastic strip material, which has the characteristics of being manually foldable and deformable (such as being bent into an arc shape to fit the inner wall of the thin wall) and maintaining its shape after deformation, so as to stably support the separator membrane and the thin wall. The top outer wall of the sleeve is vertically fixedly connected to a support rod in a direction perpendicular to the axis of the sleeve. The support rod and the top ring are made of the same material (both are malleable medical hard plastic). The top of the support rod bends and extends in the direction toward the top ring to form a hook. The hook can be elastically deformed and then snapped into the outer peripheral edge of the top ring (such as the inner wall of the hook fitting with the outer wall of the top ring to achieve the fixation of the support component and the top ring).

[0007] The aforementioned components achieve the following effects: When using an incision protection device during thoracic surgery, the soft ring is squeezed to create an opening that can pass through the patient's skin. The soft ring is then inserted into the patient's body and fixed in place. The outer surfaces of the top ring are then pinched to control its inward curling, wrapping excess thin wall material around the outer surface of the top ring. Subsequently, the diameter of the loop formed by the sleeve and connecting tube can be adjusted by sliding the two ends of the connecting tube along the inner wall of the cannula. The connecting tube or cannula is then bent to deform it, placing the cannula and connecting tube between the thin wall and the septum. The end of the hook furthest from the support rod is bent, securing the hook to the outer edge of the top ring. The cannula and connecting tube provide support for one side of the thin wall and the septum. The shape of the space inside the thin wall located on both sides of the septum is controlled by the shape of the cannula and connecting tube. Instruments can then be used to enter and exit through both sides of the septum for surgical procedures.

[0008] Preferably, at both ends of the outer surface of the connecting tube, a plurality of convex rings are linearly distributed at equal intervals along the axial direction (i.e., the length direction) of the connecting tube. The convex rings are annular protrusions integrally formed with the connecting tube (with a semi-circular cross-section, protruding 0.5-1mm from the outer wall of the connecting tube). When the connecting tube slides in the hollow cavity of the sleeve, the outer peripheral wall of the convex ring is in close contact with the inner wall of the sleeve. By increasing the sliding friction between the two, the connecting tube is prevented from accidentally sliding axially in the sleeve (such as the diameter of the annular component changing due to vibration during surgical operation).

[0009] The effect achieved by the above components is that by setting the convex ring, the friction between the two ends of the connecting pipe and the inner wall of the sleeve can be increased, thus minimizing the possibility of accidental sliding of the two ends of the connecting pipe inside the sleeve.

[0010] Preferably, a protruding rod is vertically fixed to the outer wall of the top end of the connecting tube in a direction perpendicular to the axis of the connecting tube. The protruding rod is made of the same material as the support rod (moldeable medical hard plastic). The top end of the protruding rod is bent downward in the direction toward the diaphragm (bending angle is 30-45°) to form a hook-like structure. When the annular assembly composed of the sleeve and the connecting tube is placed between the thin wall and the diaphragm, the bent part of the top end of the protruding rod can be hooked to the top edge of the diaphragm (such as the flange structure at the top of the diaphragm), forming a double fixation with the hook engaging the top ring, further improving the support stability of the annular assembly for the diaphragm.

[0011] The effect achieved by the above components is that after the sleeve and connecting pipe are fixed inside the thin wall by the hook, the bent part of the top of the protruding rod can be hung on the top of the separator membrane, further loading the sleeve and connecting pipe and improving the stability of the auxiliary structure during use.

[0012] Preferably, on the side of the hook away from the support rod (i.e., the outer peripheral wall of the hook), several anti-slip strips are linearly arranged along the length direction of the hook (from the support rod connection end to the free end). The anti-slip strips are longitudinal protrusions integrally formed with the hook (with a serrated cross-section and a height of 0.3-0.5mm). When medical staff pinch the hook with their fingers to adjust its locking position, the anti-slip strips can increase the friction between the fingers and the hook, preventing the hook from accidentally falling off due to slippage, and improving the ease of operation.

[0013] The effect achieved by the above components is that the anti-slip strip on the outer surface of the hook makes it easier to pull the hook and prevents the hand from slipping, thus improving the usability of the auxiliary structure.

[0014] Preferably, the outer peripheral wall of the top ring has a number of protrusions evenly distributed along its circumference. The protrusions are cylindrical structures (diameter 2-3mm, height 1-1.5mm) protruding outward from the outer wall of the top ring. The central angle between adjacent protrusions is 15-20°. When the hook is engaged with the outer peripheral edge of the top ring, the inner wall of the hook will be embedded in the gap between two adjacent protrusions. Through the blocking effect of the protrusions, the hook is restricted from sliding along the circumference of the top ring, thus preventing the support rod from shifting and causing the ring assembly support position to be misaligned.

[0015] The effect achieved by the above components is that when the hook is hung on the outer surface of the top ring, the protrusion can minimize the possibility of the hook sliding on the outside of the top ring, which could cause the support rod to deviate.

[0016] Preferably, both ends of the inner wall of the cannula (i.e., near the cannula port) are coaxially fixedly connected to compression rings. The compression rings are made of medical-grade silicone, and their inner diameter is smaller than that of the cannula (e.g., when the inner diameter of the cannula is 10mm, the inner diameter of the compression ring is 8mm). When the connecting tube is inserted into the cannula, the compression rings are stretched open by the connecting tube and undergo elastic deformation. Their inner walls are tightly fitted to the outer peripheral wall of the connecting tube. The elastic compression force of the silicone further restricts the axial sliding of the connecting tube within the cannula. At the same time, the compression rings can fill the gap between the cannula and the connecting tube, reducing the entry of body fluids and impurities into the cannula during the operation and improving the sealing performance of the device.

[0017] The effect achieved by the above components is that when the two ends of the connecting tube are pulled and moved inside the sleeve, the silicone extrusion ring will deform. The extrusion ring can further restrict the position of the connecting tube inside the sleeve, and increase the effect of maintaining the shape of the sleeve and the outer surface of the connecting tube after the position of the connecting tube is manually moved.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, by setting an auxiliary structure, a separator membrane is set inside the thin wall to divide the space inside the thin wall. The space inside the separator membrane is supported by a sleeve and a connecting tube, and the shape and size of the space on both sides of the separator membrane inside the thin wall are controlled. This makes it convenient for instruments to enter and exit through both sides of the separator membrane to perform surgery, and improves the practicality of the protective device.

[0021] Example 1, as Figure 1-3As shown, a surgical incision protection device for thoracic surgery patients includes a top ring 1 with a circular hollow structure. The top ring 1 is made of medical-grade rigid plastic that can be manually shaped and maintain its shape after deformation. This material not only has sufficient support strength but also allows it to adjust its shape and remain stable after external force is applied by medical staff, making it convenient to adapt to different surgical operation scenarios. A thin wall 3 is coaxially fixed to the bottom end of the top ring 1 along its own axis. The thin wall 3 is a flexible transparent medical film with uniform thickness, made of medical-grade polyetheretherketone film. It not only has good flexibility and is easy to roll, but its high transparency also allows medical staff to clearly observe the color changes of the internal tissues and the position of instruments, avoiding operational errors caused by unclear vision. The thin wall 3 can be rolled up or folded down along its own axis. After rolling, it can tightly wrap around the outer peripheral wall of the top ring 1. By adjusting the length of the roll, it can adapt to the depth requirements of different surgical incisions, ensuring that the thin wall 3 is neither too long and redundant, affecting the operation, nor too short and unable to cover the incision area. A soft ring 4 is coaxially fixed to the bottom end of the thin-walled ring 3 along the same axis. The soft ring 4 is made of elastic silicone, and its inner edge is rounded to avoid sharp edges scratching the soft tissue around the patient's incision. The outer surface of the soft ring 4 has a slightly raised anti-slip texture. When the soft ring 4 is unfolded in the patient's body, the anti-slip texture can form a slight friction with the surface of the internal tissue, further enhancing the fixation effect of the soft ring 4 in the body and preventing the device from shifting during the operation. The soft ring 4 can undergo radial contraction deformation under external pressure, such as shrinking from an initial circle to an ellipse, thereby adapting to surgical incisions of different sizes. At the same time, the elasticity of the soft ring 4 allows it to fit tightly to the tissue around the patient's incision, reducing the gap between the device and the tissue and reducing the risk of external contaminants entering the incision. Both the top ring 1 and the compression ring 210 mentioned later have the characteristics of being manually shaped and maintaining their shape after deformation, and can be flexibly adjusted according to the actual needs during the surgical operation. An auxiliary structure 2 is fixedly installed radially within the thin-walled structure 3, perpendicular to its own axis. This auxiliary structure 2 is mainly used to separate the internal space of the thin-walled structure 3, reduce cross-infection during surgery, and improve the stability of the entire device during use, ensuring smooth surgical procedures. The auxiliary structure 2 includes a separating membrane 21, two sleeves 22, and a connecting tube 25. The separating membrane 21 is a flexible medical film, with a material similar to the thin-walled structure 3 but with greater toughness, capable of withstanding slight traction during the delivery of instruments or drugs during surgery. The separating membrane 21 is completely fixed to the inner wall of the thin-walled structure 3 radially, specifically extending from one edge to the other. The edge of the separating membrane 21 is connected to the inner wall of the thin-walled structure 3 using a medical-grade heat-sealing process. The heat-sealed joint has good sealing performance, effectively preventing leakage of bodily fluids or impurities between the two independent channels, ensuring the effectiveness of channel separation. At the same time, the heat-sealed connection is strong enough not to detach due to slight external forces during surgery.Through this fixing method, the separator 21 divides the original cylindrical cavity inside the thin-walled 3 into two independent semi-cylindrical channels. These two channels can be used for different operations. For example, one channel is used for surgical instruments to enter and exit for lesion removal, hemostasis, etc., while the other channel is used for delivering drugs, saline, or inserting a suction device to remove body fluids. This avoids cross-contamination of the instrument surface by impurities or body fluids caused by sharing a single channel for different operations. Both sleeves 22 are hollow tubular structures. The inner wall of the sleeve 22 is polished to reduce the resistance when the connecting tube 25 slides, while also preventing the rough inner wall from causing wear on the surface of the connecting tube 25, thus extending the service life of the components. The connecting tube 25 is a solid rod-shaped structure. The end of the connecting tube 25 that inserts into the sleeve 22 has a tapered transition, which facilitates the smooth insertion of the connecting tube 25 into the sleeve 22. The surface of the tapered transition is smooth and will not scratch the compression ring 210 on the inner wall of the sleeve 22. Both ends of the connecting tube 25 are inserted into the interior of the two sleeves 22 from one end, forming a retractable annular support assembly of "sleeve 22-connecting tube 25-sleeve 22". Medical staff can adjust the diameter of the entire annular assembly by pushing the connecting tube 25 along the axial direction of the sleeve 22 to precisely adapt to different space requirements inside the thin-walled 3, ensuring that the support assembly can fit tightly against the thin-walled 3 and the septum 21. Both the sleeves 22 and the connecting tube 25 are made of modified medical-grade polypropylene reinforced hard plastic strip material. This material has good plasticity and stability, allowing the sleeves 22 and the connecting tube 25 to be manually folded and deformed, for example, bent into a corresponding arc shape according to the curvature of the inner wall of the thin-walled 3, and to maintain their current shape after deformation. They will not return to their original shape due to slight vibration or external force during surgery, thus stably supporting the septum 21 and the thin-walled 3 and preventing the septum 21 from collapsing due to lack of support and causing channel blockage. A support rod 23 is vertically fixed to the outer wall of the top end of the cannula 22 in a direction perpendicular to the axis of the cannula 22. The support rod 23 and the top ring 1 are made of the same material, both being malleable medical hard plastic. The length of the support rod 23 is designed to ensure that the hook 24 at its top end can extend exactly to the edge of the top ring 1. The top end of the support rod 23 bends and extends in the direction toward the top ring 1 to form the hook 24 structure. The hook 24 has a certain elastic deformation capability, and its bending angle is optimized so that it can fit tightly against the outer peripheral edge of the top ring 1 when snapped in. Medical staff can gently bend the hook 24 to deform it and snap it against the outer peripheral edge of the top ring 1. After snapping in, the inner wall of the hook 24 will fit tightly against the outer wall of the top ring 1, thereby fixing the annular support component to the top ring 1 and preventing the support component from shifting up and down during the operation.At both ends of the outer surface of the connecting tube 25, several convex rings 26 are linearly distributed at equal intervals along the length of the connecting tube 25. These convex rings 26 are annular protrusions 29 integrally formed with the connecting tube 25. The cross-section of the convex rings 26 is arc-shaped. The arc-shaped design increases the friction while preventing excessive wear between the convex rings 26 and the inner wall of the sleeve 22 when the connecting tube 25 slides, thus extending the service life of the component. The uniform spacing between adjacent convex rings 26 ensures that the connecting tube 25 receives stable friction at any position within the sleeve 22, preventing uneven local force distribution. When the connecting tube 25 slides within the hollow cavity of the sleeve 22, the outer peripheral wall of the convex rings 26 will make close contact with the inner wall of the sleeve 22. By increasing the sliding friction between them, the connecting tube 25 is prevented from accidentally sliding axially within the sleeve 22 due to vibrations or instrument collisions during surgical procedures. This ensures that the diameter of the annular support component remains stable and does not affect the normal use of the channel. A protruding rod 27 is vertically fixed to the outer wall of the top end of the connecting tube 25 in a direction perpendicular to the axis of the connecting tube 25. The protruding rod 27 and the support rod 23 are made of the same material, both being malleable medical rigid plastic. The length of the protruding rod 27 is slightly shorter than that of the support rod 23. Its top end is bent downwards in the direction towards the septum 21. The bending angle is precisely designed to form a structure similar to a hook 24, and the bent end is rounded to prevent scratching the septum 21 during attachment. The top edge of the septum 21 is pre-formed with a uniformly wide attachment edge through a heat-sealing process. The thickness of the attachment edge is slightly greater than that of the main body of the septum 21, providing a certain load-bearing capacity. The bent part of the protruding rod 27 can fit precisely below the attachment edge. After attachment, the protruding rod 27 provides slight upward support to the septum 21, which works in conjunction with the lateral support of the annular support component to keep the septum 21 flat and prevents wrinkles or displacement due to external forces during surgery. On the side of the hook 24 away from the support rod 23, several anti-slip strips 28 are linearly arranged along the length of the hook 24 (i.e., from the connecting end of the support rod 23 to the free end of the hook 24). These anti-slip strips 28 are longitudinal protrusions 29 integrally formed with the hook 24. The anti-slip strips 28 have the same height and the spacing between adjacent anti-slip strips 28 is small, forming a dense anti-slip structure. Even if the medical staff's fingers are contaminated with saline, disinfectant, or bodily fluids that may come into contact with them during the operation, they can still maintain a stable grip through the interlocking action between the anti-slip strips 28 and their fingers, preventing the hook 24 from slipping out of their hands. At the same time, the top of the anti-slip strips 28 is blunted to prevent scratching the medical staff's fingers. The outer peripheral wall of the top ring 1 has several protrusions 29 evenly distributed along the circumference of the top ring 1. These protrusions 29 are cylindrical structures that protrude outward from the outer wall of the top ring 1 and are distributed at equal angles along the circumference. The top of each protrusion 29 is hemispherical. The hemispherical design can prevent the protrusions 29 from scratching the fingers of medical staff or the surface of the hook 24.The gap width formed between two adjacent protrusions 29 is adapted to the thickness of the hook 24. When the hook 24 is engaged in the gap between adjacent protrusions 29, the protrusions 29 can limit the hook 24 from both sides, preventing the hook 24 from sliding clockwise or counterclockwise on the top ring 1. This avoids the support rod 23 from shifting due to the sliding of the hook 24, thereby preventing the support position of the annular support assembly from being misaligned, ensuring that the surgical operation can always be performed within a stable channel space. At both ends of the inner wall of the sleeve 22, compression rings 210 are coaxially fixedly connected. The compression rings 210 are made of high-elasticity medical silicone, which has a large elastic deformation range. Even if the diameter of the connecting tube 25 deviates slightly due to production errors, the compression rings 210 can still tightly fit the outer wall of the connecting tube 25 through their own elastic deformation. In addition, the inner wall of the compression rings 210 has fine anti-slip textures, which can further enhance the fixation effect on the connecting tube 25. The compression ring 210 is fixed to the inner wall of the sleeve 22 with a medical-grade adhesive. The bonding is seamless, which not only ensures the stability of the compression ring 210 inside the sleeve 22, but also prevents bodily fluids from leaking from the connection between the compression ring 210 and the sleeve 22 after entering the sleeve 22. This further improves the sealing and hygiene of the entire device and reduces the risk of infection.

[0022] Working principle: Before using the incision protection device during thoracic surgery, the entire device must be sterilized under high temperature and pressure. The sterilization process must strictly follow medical device sterilization standards to ensure that there are no bacteria, viruses, or other microorganisms remaining on the surface of all components. After sterilization, the device is removed and placed on a sterile operating table for later use. Medical staff must wear sterile gloves to ensure that all subsequent operations are performed in a sterile environment to avoid external contamination affecting surgical safety. After the surgery begins, when the protective device needs to be used, medical staff first apply a uniform external force to the soft ring 4 according to the actual size and shape of the patient's surgical incision, causing the soft ring 4 to undergo radial contraction deformation. If the surgical incision is small, a sterile dilator can be used to gently open the edge of the incision. The dilator should be used with moderate force to avoid excessive dilution that could damage the patient's incision tissue. Then, the deformed soft ring 4 is slowly inserted into the incision. During insertion, the patient's vital signs and limb responses must be closely monitored. If the patient experiences discomfort, the operation must be stopped immediately and adjustments made. After the soft ring 4 is fully inserted into the patient's body, the mouth diffuser is slowly withdrawn. The soft ring 4 gradually unfolds under its own elasticity, and the anti-slip texture on its outer surface forms a slight friction with the surface of the internal tissue. At the same time, the elasticity of the soft ring 4 allows it to fit tightly into the internal tissue, achieving stable fixation. At this time, medical staff need to gently pull the top ring 1 with their fingers to confirm whether the soft ring 4 is fixed firmly. If obvious resistance is felt when pulling and the soft ring 4 does not shift, it means that it is fixed in place. If it becomes loose, the position of the soft ring 4 needs to be readjusted until it is fixed firmly. Next, the medical staff pinched two opposite points on the outer surface of the top ring 1 with their thumb and forefinger, applying a uniform inward force to gradually curl the top ring 1 into an arc shape. During the curling process, it is important to control the force to avoid excessive force that could damage the top ring 1 or tear the thin wall 3. At the same time, it is necessary to pay attention to the curling direction of the thin wall 3 to ensure that the thin wall 3 can evenly wrap around the outer periphery of the top ring 1, and to avoid local wrinkles in the thin wall 3 that would affect subsequent visual observation and channel use. When the effective length of the thin wall 3 can be precisely matched to the depth of the surgical incision (that is, the soft ring 4 at the bottom of the thin wall 3 is fixed in the body, and the top ring 1 at the top is located at a suitable height outside the incision), the force is stopped. The top ring 1 will maintain its curled shape due to its own material properties and can be stabilized without additional fixation.Afterwards, based on the internal space size of the thin-walled 3 and the specific needs of the surgical procedure for the passage, the medical staff began to adjust the diameter of the annular support component. During the adjustment, one hand held one section of the sleeve 22 to ensure that the sleeve 22 was stable, while the other hand pinched one end of the connecting tube 25 and slowly pulled the connecting tube 25 to slide along the axial direction of the sleeve 22. During the pulling process, a slight resistance could be felt between the convex ring 26 and the inner wall of the sleeve 22. This resistance can be used as a reference for adjustment to help the medical staff judge the sliding state of the connecting tube 25. When the diameter of the annular support component was adjusted to fit the space between the inner wall of the thin-walled 3 and the septum 21 (that is, the support component can provide effective support for both without deforming the thin-walled 3 or the septum 21 due to excessive tightness), the pulling of the connecting tube 25 was stopped. At this time, the friction between the convex ring 26 on the connecting tube 25 and the inner wall of the sleeve 22 would temporarily fix the position of the connecting tube 25 and prevent it from sliding on its own. Subsequently, medical staff gently bend the connecting tube 25 or the sleeve 22 by hand, and bend the annular support component into the corresponding arc shape according to the curvature of the inner wall of the thin wall 3. During the bending process, it is necessary to ensure that the component deforms evenly and avoid excessive bending in some areas, which may cause damage. After the deformation is completed, the annular support component is slowly placed into the space between the thin wall 3 and the separator 21. When placing it, care should be taken to avoid the component scratching the thin wall 3 or the separator 21 to ensure that the surfaces of both are intact. Next, the medical staff pinched the anti-slip strip 28 on the hook 24 and gently bent the hook 24 to make it elastically deform, so that the hook 24 was snapped into the outer edge of the top ring 1. After snapping, the support rod 23 was gently shaken to confirm whether the hook 24 was snapped in place. If the support rod 23 did not move significantly when shaken, it means that the hook 24 was snapped in place firmly. If it was loose, the position of the hook 24 was readjusted and snapped in place again. At the same time, the bent part of the protrusion 27 at the top of the connecting tube 25 was aligned with the hanging edge at the top of the separator membrane 21. The protrusion 27 was slowly snapped into place below the hanging edge to complete the double fixation. At this time, the ring support assembly can stably support the thin wall 3 and the separator membrane 21. The separator membrane 21 remains flat under the support, dividing the interior of the thin wall 3 into two independent and stable channels. During the surgery, medical staff can allocate the use of the two channels according to the needs of the operation. For example, instruments such as electrocautery hooks and surgical scissors can be inserted through the channel closer to the surgeon to remove diseased tissue, ligate blood vessels, or perform hemostasis. The suction device can be inserted through the other channel to remove body fluids and tissue debris from the surgical area, or to deliver saline solution to rinse the incision and deliver the necessary surgical medications. The two channels can be used independently, which not only avoids interference between different instruments, but also prevents cross-contamination of tissue debris, body fluids, and other impurities carried on the instrument surface, effectively reducing the risk of cross-infection.Throughout the surgical procedure, the friction between the protruding ring 26 on the connecting tube 25 and the inner wall of the sleeve 22, and the elastic compression of the connecting tube 25 by the squeezing ring 210, work together to prevent the connecting tube 25 from accidentally sliding inside the sleeve 22, ensuring the diameter of the annular support assembly remains stable. The protrusion 29 on the top ring 1 limits the hooks 24 from both sides, preventing the hooks 24 from sliding along the circumference of the top ring 1, ensuring the position of the support assembly remains unchanged. The anti-slip strip 28 on the hooks 24 allows medical staff to stably grip the hooks 24 when the position needs to be temporarily adjusted. The synergistic effect of all components provides a stable operating space for the surgery. After the surgery, medical staff need to clean the two channels of any remaining tissue debris, drug residues, or bodily fluids. The channels can be rinsed and cleaned with saline solution using a suction device to ensure no foreign objects remain. After cleaning, gently pry the hook 24 to detach it from the top ring 1, then remove the protruding rod 27 from the hook edge of the diaphragm 21. Next, hold the sleeve 22 of the annular support assembly by hand and slowly remove it from between the thin wall 3 and the diaphragm 21. The removal process should be gentle to avoid scratching the diaphragm 21 or the thin wall 3 and causing damage. Finally, medical staff should hold both sides of the top ring 1 to keep it stable and slowly pull it outwards. During the pulling process, the condition of the patient's incision should be closely observed. If significant resistance is encountered, do not force it; gently adjust the pulling angle to ensure the device can be removed smoothly, avoiding damage to the patient's sutured or unsutured surgical incisions during removal. Once the soft ring 4 is completely removed from the patient's body, the removal operation of the entire device is complete. The device can then be disposed of according to medical waste disposal regulations.

Claims

1. A surgical incision protection device for thoracic surgery patients, characterized in that: The device includes a top ring (1) with a hollow annular structure. The bottom end of the top ring (1) is coaxially fixedly connected to a thin wall (3) along its axial direction. The thin wall (3) is a flexible transparent membrane structure. The thin wall (3) can be rolled up or down along its own axial direction. The bottom end of the thin wall (3) is coaxially fixedly connected to a soft ring (4) along the same axis. The soft ring (4) is made of elastic silicone material. The soft ring (4) can undergo radial shrinkage deformation under external pressure to adapt to surgical incisions of different sizes.

2. The surgical incision protection device for thoracic surgery patients according to claim 1, characterized in that: An auxiliary structure (2) is fixedly arranged radially inside the thin wall (3). The auxiliary structure (2) is used to separate the internal space of the thin wall (3), reduce cross-infection, and improve the overall stability of the device.

3. The surgical incision protection device for thoracic surgery patients according to claim 2, characterized in that: The auxiliary structure (2) includes a separator (21), two sleeves (22), and a connecting tube (25). The separator (21) is a flexible medical film. The separator (21) is completely fixed to the inner wall of the thin wall (3) along the radial direction. The separator (21) divides the cylindrical cavity inside the thin wall (3) into two independent semi-cylindrical channels for different purposes such as surgical instruments and drug delivery. The two sleeves (22) are both hollow tubular structures. The connecting tube (25) is a solid rod-shaped structure. The two ends of the connecting tube (25) are inserted from one end of the two sleeves (22). Both the sleeves (22) and the connecting tube (25) are made of modified medical grade polypropylene reinforced hard plastic strip material to stably support the separator (21) and the thin wall (3). The top outer wall of the sleeve (22) is vertically fixed with a support rod (23) in a direction perpendicular to the axis of the sleeve (22). The support rod (23) is made of the same material as the top ring (1).

4. The surgical incision protection device for thoracic surgery patients according to claim 3, characterized in that: The top end of the support rod (23) bends and extends toward the top ring (1) to form a hook (24), which can be elastically deformed and then snapped onto the outer periphery of the top ring (1).

5. The surgical incision protection device for thoracic surgery patients according to claim 4, characterized in that: At both ends of the outer surface of the connecting pipe (25), the connecting pipe (25) has several convex rings (26) linearly distributed at equal intervals along the axial direction of the connecting pipe (25). The convex rings (26) are annular protrusions integrally formed with the connecting pipe (25). When the connecting pipe (25) slides in the hollow cavity of the sleeve (22), the outer peripheral wall of the convex ring (26) is in close contact with the inner wall of the sleeve (22) to increase the sliding friction between the two and prevent the connecting pipe (25) from sliding axially in the sleeve (22) unexpectedly.

6. The surgical incision protection device for thoracic surgery patients according to claim 5, characterized in that: The top outer wall of the connecting pipe (25) is vertically fixed with a protruding rod (27) in a direction perpendicular to the axis of the connecting pipe (25). The protruding rod (27) is made of the same material as the support rod (23).

7. The surgical incision protection device for thoracic surgery patients according to claim 6, characterized in that: The top of the protruding rod (27) bends downward in the direction toward the separator membrane (21) to form a hook-like structure. When the annular assembly composed of the sleeve (22) and the connecting tube (25) is placed between the thin wall (3) and the separator membrane (21), the bent part of the top of the protruding rod (27) can be hooked to the top edge of the separator membrane (21) and the hook (24) is engaged with the top ring (1) to form a double fixation, which further enhances the support stability of the annular assembly for the separator membrane (21).

8. The surgical incision protection device for thoracic surgery patients according to claim 7, characterized in that: On the side of the hook (24) away from the support rod (23), there are several anti-slip strips (28) arranged linearly along the length of the hook (24). The anti-slip strips (28) are longitudinal protrusions integrally formed with the hook (24). When medical staff pinch the hook (24) with their fingers to adjust its locking position, the anti-slip strips (28) can increase the friction between the fingers and the hook (24) to prevent the hook (24) from accidentally falling off due to slippage.

9. The surgical incision protection device for thoracic surgery patients according to claim 9, characterized in that: The outer peripheral wall of the top ring (1) has several protrusions (29) evenly distributed along its circumference. The protrusions (29) are cylindrical structures that protrude outward from the outer wall of the top ring (1). When the hook (24) is engaged with the outer peripheral edge of the top ring (1), the inner wall of the hook (24) will be embedded in the gap between two adjacent protrusions (29). Through the blocking effect of the protrusions (29), the hook (24) is restricted from sliding along the circumference of the top ring (1), thus preventing the support rod (23) from shifting and causing the ring assembly support position to be misaligned.

10. The surgical incision protection device for thoracic surgery patients according to claim 9, characterized in that: The inner walls of the sleeve (22) are coaxially fixed with compression rings (210) at both ends. The compression rings (210) are made of medical silicone and their inner diameter is smaller than that of the sleeve (22). When the connecting tube (25) is inserted into the sleeve (22), the compression rings (210) will be stretched open by the connecting tube (25) and undergo elastic deformation. Their inner walls are tightly attached to the outer peripheral wall of the connecting tube (25). The elastic compression force of the silicone further restricts the axial sliding of the connecting tube (25) in the sleeve (22). At the same time, the compression rings (210) can fill the gap between the sleeve (22) and the connecting tube (25), reduce the entry of body fluid and impurities into the sleeve (22) during the operation, and improve the sealing of the device.
