Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a surgical incision protection device. Background Technology
[0002] Surgical incision protection devices are crucial auxiliary instruments in clinical surgery, primarily providing incision protection and shape maintenance for medical personnel performing various surgeries, isolating the surgical area from surrounding tissues. These devices typically consist of a flexible protective sleeve, positioning clasps, an incision guide structure, fixation components, and a protective layer that adheres to the tissue; some are equipped with basic adjustment components. In use, the device is first precisely inserted into the incision via the guide structure, then locked in position using the clasps and fixation components. The protective sleeve maintains the incision's expanded shape, making it an important auxiliary device for ensuring sufficient operating space during clinical surgery.
[0003] Traditional surgical incision protection devices typically consist of a main channel, a fixing ring, and a support structure. The fixing ring secures the main channel to the surgical incision, which in turn opens the incision to create a surgical access channel, facilitating the insertion of instruments such as thoracoscopes for tissue separation and resection, while preventing direct friction between instruments and incision tissue to reduce damage. However, existing surgical incision protection devices only provide basic incision opening and protection. When using instruments such as electrocautery to remove tissue during surgery, a large amount of smoke is easily generated. This smoke remains in the thoracic cavity and cannot be expelled in time. It not only severely interferes with the visual effect of the thoracoscope, causing blurred surgical vision and affecting the accuracy and efficiency of the surgery, but also diffuses into the surgical environment. The harmful particles and gases contained in this smoke may be inhaled by medical staff, causing potential damage to their respiratory system. Summary of the Invention
[0004] This invention addresses the shortcomings of existing technologies by providing a surgical incision protection device. Through the cooperation of structures such as sliding grooves and smoke exhaust components, it solves the problems of surgical smoke retention and inability to be discharged in a timely manner, which interfere with the thoracoscopic field of view, affect the accuracy of surgery, and endanger the health of medical staff.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A surgical incision protection device includes a protective sleeve with a retaining ring, an insertion ring at the bottom of the protective sleeve, an arc-shaped plate on the insertion ring, a protective layer at the bottom of the arc-shaped plate, a pull rod on the protective sleeve, a lifting plate on the pull rod, and sliding grooves on the protective sleeve and retaining ring. The device is guided smoothly and accurately into place by the insertion ring and arc-shaped plate, conforming to the shape of the incision and reducing tissue friction and damage. It also includes a smoke extraction component installed within the sliding groove, which collects and filters surgical smoke to ensure clear vision and medical staff safety.
[0006] Preferably, the smoke exhaust component includes an elastic block that is slidably connected inside a sliding groove. A spring is installed on the elastic block, with one end of the spring mounted on the elastic block and a clip plate installed at the end of the spring away from the elastic block. This allows the smoke exhaust component to flexibly adjust its position along the sliding groove to meet smoke collection needs, and facilitates the elastic support of the clip plate by the spring, thereby improving the ease of adjustment of the smoke exhaust component.
[0007] Preferably, a limiting groove is provided on the inner wall of the sliding groove, and a limiting block adapted to the limiting groove is installed on the spring clip. The limiting block is located in the limiting groove, which helps to limit the sliding range of the spring clip in the sliding groove, prevent it from deviating from the track, facilitate the structural stability of the smoke exhaust component during adjustment, and prevent displacement.
[0008] Preferably, the elastic block has a smoke inlet hole, a smoke exhaust pipe is installed on the elastic block, and a base is installed on the elastic block. Both the base and the elastic block have matching positioning holes, and positioning bolts are threaded into the positioning holes. This facilitates the rapid introduction of surgical smoke into the smoke exhaust pipe through the smoke inlet hole, improves the smoke collection efficiency, and makes it easy to securely connect the base and the elastic block with the positioning bolts to prevent the base from loosening.
[0009] Preferably, a damping rotary joint is movably connected to the base, and a bracket is installed on the damping rotary joint. The end of the bracket away from the damping rotary joint is clamped and fixed to the exhaust pipe. This allows for flexible adjustment of the bracket angle through the damping rotary joint to adapt to different installation positions of the exhaust pipe, and facilitates the bracket to firmly clamp the exhaust pipe, preventing the exhaust pipe from shifting.
[0010] Preferably, a filter canister is installed on the exhaust pipe, a filter screen is installed inside the filter canister, and a smoke concentration sensor is installed on the filter screen. This helps the filter screen to filter harmful particulate matter in the smoke, reduce the emission of harmful gases, and allows the smoke concentration sensor to monitor the smoke concentration in real time and keep track of the smoke exhaust situation.
[0011] Preferably, the filter canister is equipped with a control valve, and the control valve is equipped with a guide tube. This allows for precise adjustment of the smoke discharge rate through the control valve, preventing smoke retention and facilitating the directional discharge of filtered smoke through the guide tube, thus ensuring a clean surgical environment.
[0012] Preferably, a support plate is installed on the inner wall of the clasp, a clamping ring is installed on the support plate, and an anti-displacement pad is installed on the clamping ring. This helps the support plate provide stable support for the clamping ring, enhances the strength of the clamping structure, and facilitates the anti-displacement pad to increase the friction between the clamping ring and the instrument, thus preventing the surgical instrument from shifting.
[0013] Preferably, a fixing plate is installed on the outside of the retaining ring. The fixing plate has anti-slip texture, which helps to increase the contact area between the device and the surgical area, improve the fixing effect of the device, and facilitates the anti-slip texture to increase friction and prevent the device from sliding during surgery.
[0014] Preferably, the filter canister is made of medical-grade ABS material, and the filter screen is woven from medical-grade stainless steel. This design ensures the durability of the filter canister with the medical-grade ABS material, facilitates the improvement of smoke filtration effect with the medical-grade stainless steel filter screen, and is also corrosion-resistant and easy to clean.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through its designed smoke extraction component, enables the smoke extraction pipe to adjust its angle and flexibly move along the sliding groove during surgical procedures such as thoracoscopic surgery, when the position and concentration of smoke generated by the electrocautery cutting tissue change. This differs from traditional devices that can only open the incision without smoke extraction. It ensures that during surgery, both concentrated smoke deep in the incision and diffuse smoke can be quickly introduced through the smoke inlet and efficiently filtered by the filter screen. This truly achieves the integration of incision protection and real-time smoke purification and directional extraction, greatly improving the clarity of the surgical field and the occupational health protection of medical staff.
[0016] 2. This invention, through the synergistic structure of the designed guide ring, arc-shaped plate, support plate, clamping ring, and fixation plate, enables the guide ring to guide the incision contour during thoracoscopic and other surgeries, the arc-shaped plate to provide buffering and fit with the protective layer, the support plate to provide stable support for the clamping ring, the clamping ring to limit the instrument through friction, and the fixation plate to increase the contact area and enhance fixation. This, in turn, drives the protective sleeve to be inserted smoothly and accurately to reduce tissue friction and stabilize and limit the surgical instrument to prevent displacement. Unlike traditional protective devices that can only simply open the incision without precise guidance and instrument clamping functions, this invention ensures that throughout the entire surgical process, whether it is the adaptation and protection of different incision shapes or the prevention of displacement of intraoperative instruments, the corresponding structure can effectively achieve the integration of basic incision protection, insertion adaptation, and instrument limiting.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1: like Figures 1-8 As shown in the diagram, a surgical incision protection device includes a protective sleeve 1, a retaining ring 2 mounted on the protective sleeve 1, an inlet ring 3 mounted on the bottom of the protective sleeve 1, an arc-shaped plate 4 mounted on the inlet ring 3, a protective layer 5 covering the bottom of the arc-shaped plate 4, a pull rod 6 mounted on the protective sleeve 1, a lifting plate 7 mounted on the pull rod 6, and sliding grooves 8 formed on the protective sleeve 1 and the retaining ring 2. The device is guided smoothly and accurately by the inlet ring 3 and the arc-shaped plate 4 to conform to the shape of the incision and reduce tissue friction and damage. A smoke extraction component 9 is also installed in the sliding groove 8 to collect and filter surgical smoke, ensuring clear vision and medical staff safety.
[0021] The following is in conjunction with the appendix Figures 1-8 The smoke exhaust component 9 includes an elastic block 10, which is slidably connected inside the sliding groove 8. A spring 11 is installed on the elastic block 10, with one end of the spring 11 installed on the elastic block 10 and a spring clip 12 installed at the end of the spring 11 away from the elastic block 10. This allows the smoke exhaust component 9 to flexibly adjust its position along the sliding groove 8 to meet the smoke collection requirements, and facilitates the elastic support of the spring clip 12 by the spring 11, thereby improving the ease of adjustment of the smoke exhaust component 9. Then, through the designed smoke exhaust component 9, during thoracoscopic and other surgical operations, when the electrocautery cuts tissue and generates smoke, and the position and concentration of the smoke change, the elastic block 10 is subjected to the elastic force of the spring 11 and the limiting effect of the sliding groove 8, which in turn drives the smoke exhaust pipe 16 to adjust its angle through the damped rotation joint 20 and move flexibly along the sliding groove 8. Unlike traditional devices that can only open the incision without smoke exhaust function, this ensures that during the operation, whether it is concentrated smoke deep in the incision or diffuse smoke, it can be quickly introduced by the smoke inlet 15 and efficiently filtered by the filter screen 23. It truly realizes the integration of incision protection and real-time smoke purification and directional exhaust, which greatly improves the clarity of the surgical field and the occupational health protection effect of medical staff.
[0022] In addition, a limiting groove 13 is provided on the inner wall of the sliding groove 8, and a limiting block 14 that matches the limiting groove 13 is installed on the spring clip 12. The limiting block 14 is located in the limiting groove 13, which helps to limit the sliding range of the spring clip 12 in the sliding groove 8, prevent it from leaving the track, and facilitate the structural stability of the smoke exhaust component 9 during adjustment, preventing displacement. Meanwhile, the elastic block 10 is provided with a smoke inlet hole 15, a smoke exhaust pipe 16 is installed on the elastic block 10, and a base 17 is installed on the elastic block 10. Both the base 17 and the elastic block 10 are provided with matching positioning holes 18. The positioning holes 18 are internally threaded with positioning bolts 19, which facilitates the rapid introduction of surgical smoke into the smoke exhaust pipe 16 through the smoke inlet hole 15, improves the smoke collection efficiency, and makes it easy to securely connect the base 17 and the elastic block 10 with the positioning bolts 19 to prevent the base 17 from loosening. Example 2: Figures 1-8 As shown, this embodiment further explains Example 1.
[0023] The base 17 is movably connected to a damping rotary joint 20, on which a bracket 21 is installed. The end of the bracket 21 away from the damping rotary joint 20 is clamped and fixed to the exhaust pipe 16. This allows for flexible adjustment of the bracket 21's angle via the damping rotary joint 20 to accommodate different installation positions of the exhaust pipe 16. It also facilitates the bracket 21's stable clamping of the exhaust pipe 16 and prevents displacement of the exhaust pipe 16. A filter canister 22 is installed on the exhaust pipe 16, and a filter screen 23 is installed inside the filter canister 22. A smoke concentration sensor 24 is installed on the filter screen 23. This allows the filter screen 23 to filter harmful particulate matter in the smoke, reducing the emission of harmful gases. It also allows the smoke concentration sensor 24 to monitor the smoke concentration in real time and promptly grasp the smoke exhaust situation.
[0024] In addition, a control valve 25 is installed on the filter canister 22, and a guide tube 26 is installed on the control valve 25. This allows for precise adjustment of the smoke discharge rate through the control valve 25, preventing smoke from accumulating and facilitating the directional discharge of filtered smoke through the guide tube 26, thus ensuring a clean surgical environment.
[0025] Meanwhile, a support plate 27 is installed on the inner wall of the retaining ring 2, a clamping ring 28 is installed on the support plate 27, and an anti-displacement pad 29 is installed on the clamping ring 28. This helps the support plate 27 to provide stable support for the clamping ring 28, enhances the strength of the clamping structure, and makes it easier for the anti-displacement pad 29 to increase the friction between the clamping ring 28 and the instrument, thus preventing the surgical instrument from shifting.
[0026] Specifically, a fixing plate 30 is installed on the outside of the retaining ring 2. The fixing plate 30 is provided with anti-slip texture 31, which helps to increase the contact area between the device and the surgical area, improve the fixing effect of the device, and facilitates the anti-slip texture 31 to increase friction and prevent the device from sliding during surgery.
[0027] Finally, the filter canister 22 is made of medical-grade ABS material, and the filter screen 23 is woven from medical-grade stainless steel material. The medical-grade ABS material helps ensure the durability of the filter canister 22, and the medical-grade stainless steel filter screen 23 can improve the smoke filtration effect, and is also corrosion-resistant and easy to clean.
[0028] In summary, when using this device: First, medical staff must perform routine disinfection of the surgical incision area. Then, holding the retaining ring 2 and pull rod 6 of the device, they align the guide ring 3 at the bottom of the protective sleeve 1 with the surgical incision. Using the guiding action of the guide ring 3 and the conforming design of the arc-shaped plate 4, the protective sleeve 1 is slowly pushed into the incision. The protective layer 5 at the bottom of the arc-shaped plate 4 directly contacts the surrounding tissue, effectively reducing friction and scratching damage to the skin and subcutaneous tissue during device insertion. During insertion, the insertion depth of the protective sleeve 1 can be flexibly adjusted by pulling the lifting plate 7 at the top of the pull rod 6, ensuring that the protective sleeve 1 completely covers the incision and forms a stable surgical operating channel. After the protective sleeve 1 is in position, the fixing plate 30 on the outside of the retaining ring 2 will conform to the skin or dressing around the surgical area. The anti-slip texture 31 on the fixing plate 30 increases the friction with the contact surface, preventing the device from shifting during subsequent surgical operations and providing a stable foundation for incision protection during the surgery.
[0029] Secondly, after the main body of the device is fixed, the smoke exhaust component 9 in the sliding groove 8 needs to be adjusted. Medical personnel, according to the expected operating area of instruments such as the electrosurgical unit in the surgical plan, push the elastic block 10 along the sliding groove 8 to adjust the initial position of the smoke exhaust pipe 16. The spring 11 between the elastic block 10 and the spring clip 12 provides elastic support, ensuring that the spring clip 12 always fits against the inner wall of the sliding groove 8. Simultaneously, the limiting block 14 on the spring clip 12 slides along the limiting groove 13 on the inner wall of the sliding groove 8, preventing the elastic block 10 from disengaging from the track of the sliding groove 8 during movement. The base 17 is fixed to the elastic block 10 by positioning bolts 19. The angle of the bracket 21 is then adjusted by the damping rotation joint 20 on the base 17, ensuring that the end of the bracket 21 away from the damping rotation joint 20 precisely clamps the smoke exhaust pipe 16, ensuring that the smoke inlet of the smoke exhaust pipe 16 is aligned with the expected smoke generation point.
[0030] Then, once the surgery officially begins, when the electrocautery cuts tissue and generates smoke, the smoke first diffuses into the surgical channel opened by the protective sleeve 1. Subsequently, guided by the natural airflow in the surgical area and the negative pressure created by the external negative pressure device of the exhaust pipe 16, it enters the interior of the exhaust pipe 16 through the smoke inlet 15 on the elastic block 10. When the smoke is transported to the filter canister 22 along the exhaust pipe 16, the filter screen 23 inside the filter canister 22 traps harmful particles in the smoke, reducing the direct emission of harmful gases and particles. At the same time, the smoke concentration sensor 24 on the filter screen 23 monitors the smoke concentration in real time. If the concentration is too high, medical staff can adjust the control valve 25 on the filter canister 22 to increase the smoke discharge rate and prevent smoke from lingering in the surgical channel, causing blurred vision. If the concentration is low, the opening of the control valve 25 can be appropriately reduced to maintain stable airflow in the surgical area. In addition, when using instruments such as thoracoscopic instruments during surgery, the instruments need to pass through the clamping ring 28 on the inner wall support plate 27 of the clamping ring 2. The anti-displacement pad 29 on the inner wall of the clamping ring 28 will be in close contact with the instrument surface, limiting the radial movement of the instrument through friction, ensuring the accuracy of the surgical operation, and further working with the smoke exhaust component 9 to ensure a clear surgical field.
[0031] Finally, after the surgery, medical staff must first shut off the negative pressure device connected to the drainage tube 26 and the control valve 25 on the filter canister 22 to prevent external air from backflowing and carrying contaminants into the surgical area. Since the positioning bolt 19 is used to fix the base 17 and the elastic block 10, the positioning bolt 19 must be loosened first to release the base 17 from its fixed state. At this time, the base 17 can move flexibly with the damping rotation joint 20, thereby removing the clamping of the exhaust pipe 16 by the bracket 21. Then, slide the elastic block 10 along the sliding groove 8 to a position easy to remove, and then remove the drainage tube 26, filter canister 22, and exhaust pipe 16 in sequence. Inspect the filter screen 23 inside the filter canister 22. If it is a disposable component, replace it directly; if it is a reusable component, sterilize and clean it at high temperature. Afterwards, holding the lifting plate 7 on the pull rod 6, slowly pull the protective sleeve 1 out of the surgical incision. The guide ring 3 and the arc-shaped plate 4 can again serve as a guide to prevent the protective sleeve 1 from scraping the incision healing tissue when it is removed. Finally, the retaining ring 2, fixing plate 30 and other components are cleaned and disinfected, and the elasticity of spring 11 and the flexibility of damping rotary joint 20 are checked to prepare for the subsequent storage and reuse of the device.
