Abstract
Description
Technical Field
[0001] This invention relates to a scab removal device, and more particularly to a scab removal device for burn wound care. Background Technology
[0002] Debridement of eschar after deep burns is a crucial step in burn treatment. While surgical escharotomy is the gold standard, it is highly invasive. As a supplementary or alternative method, mechanical escharotomy physically removes necrotic tissue using a high-speed rotating abrasive head, offering advantages such as intuitive operation and good adaptability to uneven wound surfaces. However, this technique suffers from two interconnected and unresolved core drawbacks in clinical application, severely limiting its efficacy and safety.
[0003] First, regarding the issue of tissue thermal damage during the abrasion process. Current abrasion devices generally employ primitive and inefficient heat management methods. They primarily rely on spraying room-temperature or chilled saline solution onto the wound for cooling during abrasion. This method has inherent limitations, interfering with the surgical field and manipulation: large amounts of irrigation fluid mix with blood and tissue debris, severely obscuring the surgical field and affecting the surgeon's judgment of debridement depth and boundaries. Simultaneously, the liquid may cause the equipment to slip, affecting the precision of the operation.
[0004] Secondly, there is the issue of tissue debris contamination from dermabrasion. The large amount of tiny tissue particles, blood, and exudate mixture generated during escharotomy presents another significant challenge. Current techniques typically employ simple lateral suction tubes or postoperative irrigation, which are ineffective. Delayed removal and secondary contamination occur because the lateral suction tube, located behind or to the side of the dermal head, cannot capture debris immediately upon its generation. A large amount of debris initially splashes and contaminates the area surrounding the wound, potentially being carried into deep interstitial spaces or open small blood vessels and lymphatic vessels, posing a theoretical risk of embolism and exacerbating the inflammatory response, before being partially removed.
[0005] In summary, existing eschar removal techniques are limited by two intertwined problems: the cooling spray affecting the surgical field of vision and interfering with the procedure, and the untimely removal of debris leading to secondary contamination. This invention aims to fundamentally solve these problems. Summary of the Invention

[0028] Advantages of this invention:
[0029] 1. The technical solution of this application adopts an internal circulation cooling method for eschar removal, maintaining a dry and clear surgical field. Through internal closed-loop cooling rather than external spraying, there is no excess liquid interference in the eschar removal area. The surgeon can clearly and unobstructedly observe the color, texture, and bleeding of the eschar removal wound, thereby more accurately determining the debridement boundary (the boundary between necrotic and healthy tissue), significantly improving the precision and safety of the surgery.
[0030] 2. The technical solution of this application achieves "immediate removal upon generation" of debris, enabling in-situ, synchronous, and real-time collection. Through airflow ejected from above the grinding surface, debris is instantly engulfed and directionally removed from the wound surface the moment it is generated. This mechanism completely changes the passive "contaminate first, clean later" mode of traditional techniques, achieving a cleaner surgical procedure. Simultaneously, the blown-out debris is drawn back into the collection component, and the real-time removal mechanism almost completely prevents tissue debris and blood from contaminating the surrounding healthy skin, surgical field, and deep tissue spaces, greatly reducing the risk of postoperative infection and inflammatory reactions, and significantly improving patient safety.

[0044] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.
[0045] This application provides a burn wound debridement device.
[0046] Example 1, such as Figure 1-7 As shown.
[0047] A burn wound debridement device includes an outer casing 1, which is a hollow box structure with an open bottom. An operating handle 11 is provided on the top surface of the outer casing 1. Doctors perform debridement by holding the operating handle 11. The operating handle 11 has an inner groove in the middle for easy gripping by the doctor.
[0048] A burn wound descaling device includes a descaling component 2, which is installed inside the outer casing 1;
[0049] The descalding assembly 2 includes a descalding box 21, a telescopic push rod 22, a descalding motor 23, a motor support 24, a support slider 25, a support slide rail 26, a transmission rod 27, and a descalding cutter head 28. The descalding box 21 is provided on the top surface of the inner cavity of the outer housing 1. The descalding box 21 is a hollow structure with an open bottom. The telescopic push rod 22 is installed on the top surface of the descalding box 21. Several support slide rails 26 are vertically installed on the side wall of the descalding box 21. The support slider 25 is slidably connected in the support slide rail 26. The other end of the support slider 25 is fixedly connected to the motor support 24. A motor is installed on the top surface of the motor support 24. The output end of the telescopic push rod 22 is fixedly connected to the descalding motor 23. The output end of the descalding motor 23 extends to the bottom of the motor support 24 and is provided with a transmission rod 27. The bottom end of the transmission rod 27 is provided with a descalding cutter head 28.
[0050] The telescopic push rod 22 is an electric push rod. Its extension and retraction cause the motor support 24 to slide up and down along the support slide rail 26, thereby causing the eschar removal blade 28 to extend or retract from the lower opening of the eschar removal box 21. Normally, when not removing eschar, the eschar removal blade 28 retracts to the inside of the eschar removal box 21 under the action of the telescopic push rod 22. When eschar removal is needed, the telescopic push rod 22 extends the eschar removal blade 28, and the doctor, holding the operating handle 11, can remove the eschar from the wound surface using the eschar removal blade 28. During eschar removal, the eschar removal motor 23 operates, driving the eschar removal blade 28 to rotate and grind away the eschar.
[0051] The descaling head 28 includes a blade disc 281 and descaling blades 282. Several descaling blades 282 are mounted on the bottom surface of the blade disc 281. The descaling blades 282 contact the eschar and perform grinding.
[0052] The blade disc 281 has a hollow structure, and the top surface of the eschar removal blade 282 is equipped with heat dissipation fins 283. These fins penetrate the bottom surface of the blade disc 281 and extend to the center of its inner cavity. The blade disc 281 is filled with coolant. During eschar removal, the heat dissipation fins 283 are immersed in the coolant, allowing the heat generated by the eschar removal blade 282 during grinding to be dissipated in a timely manner, thus cooling the blade. This prevents secondary damage to the wound from the heat generated during grinding. Furthermore, cooling within the blade disc 281 maintains a dry and clear surgical field of vision. Through internal closed-loop cooling rather than external spraying, there is no excess liquid interference in the eschar removal area. The surgeon can clearly and unobstructedly observe the color, texture, and bleeding of the eschar removal wound, thereby more accurately determining the debridement boundary (the boundary between necrotic and healthy tissue), significantly improving the precision and safety of the surgery.
[0053] A cooling assembly 3 is installed on the top surface of the cutter head 281 to further enhance the cooling effect of the descaling head 28.
[0054] The cooling assembly 3 includes an air-cooled duct 31, an inlet ring 32, an outlet ring 33, a circulating pump 34, an axial flow fan 35, an air duct 36, and a mesh screen 37. An inlet ring 32 is installed at the bottom of the side wall of the cutter disc 281. An inlet hole is opened through the inner side wall of the inlet ring 32. All inlet holes are opened at an angle, and the central axis of the inlet hole is perpendicular to the diameter of the circle in which the inlet ring 32 is located. The inlet hole extends into the inner cavity of the cutter head 281. A plurality of air-cooled pipes 31 are installed on the top surface of the cutter head 281, and an outlet ring 33 is installed on the top surface of each air-cooled pipe 31. The air-cooled pipes 31 are spiral-shaped, with both ends connected to the inner cavities of the cutter head 281 and the outlet ring 33, respectively. A circulation pump 34 is installed on the top surface of the cutter head 281. The input end of the circulation pump 34 is connected to the outlet ring 33, and the output end of the circulation pump 34 is connected to the inlet ring 32 via pipes. Air ducts 36 are installed through both sides of the outer casing 1. The inner ends of the air ducts 36 extend into the inner cavity of the descaling box 21. An axial flow fan 35 is installed on the side of the air duct 36 near its outer end, and a mesh screen 37 is installed on the outer end of the air duct 36. The two axial flow fans 35 rotate in the same direction.
[0055] During the descaling process, the two axial flow fans 35 are activated, causing air to flow in from one duct 36 and out from the other, creating a directional airflow. The high-speed airflow cools the air ducts. Heat from the descaling blade 282 is transferred to the coolant through the heat dissipation fins 283. The coolant is drawn and pumped out by the circulation pump 34 for circulation. During circulation, the circulation pump 34 pumps the coolant into the inlet ring 32, and then into the inner cavity of the blade disc 281 through the inlet hole. Because the central axis of the inlet hole is perpendicular to the diameter of the circle containing the inlet ring 32, the coolant flows within the inner cavity of the blade disc 281 and contacts the heat dissipation fins 283, which transfer heat from the descaling blade 282 to the coolant. Coolant flows from the top of the inner cavity of the cutter head 281 into the air-cooling pipe 31. The air-cooling pipe 31 is directly blown by the directional airflow formed by the two air ducts 36. The coolant transfers heat to the air-cooling pipe 31, and then the high-speed airflow further cools the air-cooling pipe 31. Therefore, the high-temperature coolant flows through the air-cooling pipe 31, is cooled, and then flows to the outlet ring 33. Finally, the circulating pump 34 pumps the coolant out of the outlet ring 33. This completes one full circulation of the coolant, achieving rapid internal cooling of the grinding tool.
[0056] The cutter head has many structures installed and set on its top surface, so the various structures are symmetrically distributed, which makes the cutter head remain stable during rotation.
[0057] The bottom surface of the blade disc 281 is equipped with a puncture element 29. This element is used to puncture the eschar, thereby draining the blood clots, pus, and other fluids inside.
[0058] The puncture device 29 includes a puncture box 291, a puncture push rod 292, and a puncture needle 293. The puncture box 291 is installed at the center of the bottom surface of the inner cavity of the blade disc 281. A puncture hole is formed at the center of the bottom surface of the puncture box 291. The puncture push rod 292 is installed on the top surface of the inner cavity of the puncture box 291, directly above the puncture hole. The puncture needle 293 is installed at the output end of the puncture push rod 292. Driven by the puncture push rod 292, the puncture needle 293 extends from the puncture hole to below the puncture box 291. The puncture push rod 292 is an electrically operated push rod that can extend and retract. The puncture push rod 292 drives the puncture needle 293 to extend from the puncture hole at the bottom of the puncture box 291, thereby performing a puncture operation on the eschar.
[0059] During puncture, the puncture push rod 292 drives the puncture needle 293 to extend, and then the desquamation motor 23 starts, driving the puncture needle 293 to rotate, so as to puncture the eschar.
[0060] A burn wound eschar removal device includes a collection component 4 installed at the lower end of the eschar removal component 2, which "removes as it is generated" during the eschar removal process, achieving in-situ and synchronous immediate collection.
[0061] The collection assembly 4 includes a collection box 41, a collection mesh bag 42, a back suction pump 43, a back suction ring 44, and an inner shrink plate 45. The back suction ring 44 is provided at the bottom of the inner cavity of the scab removal box 21, and the back suction ring 44 is flush with the lower end face of the scab removal box 21. The suction ring 44 is adapted to the inner shape of the descaling box 21. The suction ring 44 is a hollow structure with an open bottom. An inner shrink plate 45 is provided on the bottom surface of the suction ring 44. The inner shrink plate 45 is an inclined structure, with the side of the bottom surface closer to the descaling component 2 being higher than the side farther away from the descaling component 2. A plurality of collection holes 451 are evenly spaced through the surface of the inner shrink plate 45. A collection box 41 is installed on the top surface of the outer box 1. The collection box 41 is an openable structure. A collection mesh bag 42 is fitted inside the collection box 41. A suction pump 43 is installed on the outside of the collection box 41. The suction pump 43 sucks in debris and other impurities generated during the descaling process and transports them to the collection mesh bag. After each descaling operation, the collection box 41 is opened and the collection mesh bag 42 is replaced. The suction pump 43 is connected to the collection box 41 and the suction ring 44 through pipes. The back-suction pump 43 draws air from the back-suction ring 44 into the collection mesh bag 42 inside the collection box 41, creating a negative pressure state inside the back-suction ring 44. This allows the scabbed debris and blood generated during grinding to be drawn into the collection mesh bag 42 through the collection holes 451 on the surface of the inner shrink plate 45. This "generation-and-removal" approach achieves in-situ, synchronous, and immediate collection of debris generated during the descabbing process.
[0062] The collection component 4 includes a blower pump 46, a cooling air duct 47, and a high-speed gas ring 48. The blower pump 46 is installed on the top surface of the cutter head 281. The cooling air duct 47 is provided in the inner cavity of the cutter head 281. Several high-speed gas rings 48 are provided below the cutter head 281. The blower pump 46 and the cooling air duct 47, and the cooling air duct 47 and several high-speed gas rings 48 are all connected by pipes. Several gas ducts are inclined through the high-speed gas rings 48, and the lower end of the gas ducts is inclined towards the edge of the cutter head 281.
[0063] The blower pump 46 pumps air into the cooling air duct 47, which is located inside the blade disc cavity and is immersed in coolant, thus cooling the air inside to a certain extent. The cooled air then flows into the high-speed gas ring 48 and is ejected through the gas duct to the abrasive wound. The airflow ejected from above the abrasive surface can instantly engulf and directionally remove debris from the wound. This mechanism completely changes the passive "contaminate first, clean later" mode of traditional technology, achieving a cleaner surgical procedure. At the same time, the blown debris is drawn back by the collection hole 451, and the immediate removal mechanism almost completely prevents tissue debris and blood from contaminating the surrounding healthy skin, surgical field, and deep tissue gaps, greatly reducing the risk of postoperative infection and inflammatory response, and significantly improving patient safety.
[0064] A burn wound eschar removal device includes a softening component 5, installed between the outer casing 1 and the eschar removal component 2. The softening component 5 uses ultrasound to soften the eschar, loosening it to facilitate subsequent eschar removal, while protecting viable tissue and creating conditions for healing.
[0065] The softening assembly 5 includes an electrical box 51, a softening box 52, an ultrasonic generator 53, transducers 54, a softening plate 55, and a connecting ring 56. The electrical box 51 is mounted on the top surface of the outer casing 1, and the ultrasonic generator 53 is installed inside the electrical box 51. The softening box 52 is located on the top surface of the inner cavity of the outer casing 1. The softening box 52 is a hollow structure with an open bottom and is located outside the descaling assembly 2. A connecting ring 56 is detachably mounted on the bottom end of the side wall of the softening box 52. The bottom surface of the connecting ring 56 is provided with the softening plate 55. Several transducers 54 are mounted on the top surface of the softening plate 55, and the transducers 54 are connected to the ultrasonic generator 53 via an electrical circuit. When the transducers 54 are mounted on the top surface of the softening plate 55, they are designed for resonance. Multiple transducers 54 work simultaneously to ensure uniform vibration distribution across all positions of the softening plate 55.
[0066] During the softening procedure, after applying a suitable medium such as coupling agent or saline solution to the eschar surface, the ultrasound generator 53 is activated to drive the transducer 54. The doctor holds the eschar abrasive and brings the softening plate 55 into contact with the eschar on the wound surface, using ultrasound to soften the eschar.
[0067] A shock-absorbing ring is detachably installed between the softening plate 55, the scab removal component 2, and the outer casing 1. This reduces vibration felt by medical staff holding the device and increases operational comfort.
[0068] A burn wound care eschar removal device includes an application component 6, which is installed on the outside of the outer casing 1 to apply a medium such as a coupling agent.
[0069] The application assembly 6 includes an extension plate 61, a motor frame 62, a transmission motor 63, a transmission gear 64, a transmission gear ring 65, a suspension frame 66, an application push rod 67, an application motor 68, and an application plate 69. The bottom surface of the outer casing 1 is provided with several extension plates 61. A transmission gear ring 65 is slidably connected to the top surface of each extension plate 61. A motor frame 62 is mounted on the top surface of any one of the extension plates 61. A transmission motor 63 is mounted inside the motor frame 62. A transmission gear 64 is provided at the output end of the transmission motor 63, and the transmission gear 64 meshes with the transmission gear ring 65. A suspension frame 66 is provided on the bottom surface of the transmission gear ring 65. An application push rod 67 is mounted inside the suspension frame 66. An application motor 68 is mounted at the output end of the application push rod 67. An application plate 69 is mounted on the output shaft of the application motor 68. Several nozzles 691 are mounted on the bottom surface of the application plate 69. The application push rod 67 is an electric push rod that can be extended and retracted to move the application plate 69 to the bottom of the outer casing 1 for application, thus avoiding contact between other parts of the scab remover and the wound surface during the application process.
[0070] A storage box 661 is provided on the outside of the suspension frame 66, and an application pump 662 is installed on the outside of the storage box 661. The application pump 662 is connected to the storage box 661 and the application plate 69 through pipes.
[0071] During application, the drive motor 63 starts, driving the drive gear ring 65 to rotate via the drive gear 64, thereby adjusting the position of the application push rod 67. Once adjusted, the application push rod 67 extends, moving the application plate 69 downwards. Then, the application motor 68 is started to adjust the position of the application plate 69, aligning it with the wound surface. Finally, the application pump 662 is started to pump the medium from the storage tank 661 into the application plate 69, which is then sprayed onto the patient's wound surface through the nozzle 691. This completes the medium application operation.
[0072] When using this invention:
[0073] To pre-treat the eschar softening process, the application unit is activated to apply the medium required for ultrasonic softening to the eschar surface.
[0074] To perform ultrasonic softening, the ultrasonic generator is activated to drive the transducer. The doctor holds an eschar remover and places the softening plate in contact with the eschar on the wound surface, using ultrasound to soften the eschar. After the softening process is complete, the suction assembly is activated to suck back the media and detached debris.
[0075] To perform the eschar removal procedure, the cooling assembly is first activated. Then, the telescopic push rod extends the eschar removal head, the eschar removal motor operates, and the eschar removal head rotates. The doctor holds the operating handle and can then use the eschar removal head to grind and remove the eschar from the wound surface.
