Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a surgical debridement device. Background Technology

[0002] Surgical debridement is a common surgical procedure involving the removal of necrotic and inflamed tissue around a wound to promote healing and prevent infection. The techniques involved in surgical debridement include using tools such as scalpels, scissors, and suture forceps to remove and excise necrotic and inflamed tissue around the wound. During debridement, the surgeon must carefully observe the wound to ensure complete removal of all necrotic and inflamed tissue while avoiding damage to healthy tissue. The background techniques for surgical debridement include knowledge of the physiological processes of wound healing and infection prevention, proficiency in the use of surgical tools and equipment, and the ability to accurately assess and manage the patient's wound condition. Furthermore, surgeons need extensive clinical experience and surgical skills to ensure the safe and effective execution of the debridement procedure.

[0003] A search revealed Chinese patent number CN202020035838.5, which discloses a surgical debridement device for limbs, comprising a base plate, a storage box, a height-adjustable pneumatic rod, a support column, a disinfectant collection device, a debridement table, a debridement fixation device, a fixation column, and an ultraviolet disinfection lamp. The height-adjustable pneumatic rod is mounted on the base plate for adjusting the height. The storage box is mounted on the height-adjustable pneumatic rod and can be used to place medical devices. The support column is mounted on the height-adjustable pneumatic rod. The debridement table is mounted on the support column and is used to place the patient's wound requiring debridement. The disinfectant collection device is located inside the debridement table.

[0004] The beneficial effects of the above-mentioned device are: simple operation, compact structure, and reasonable design. It utilizes the principle that applying an electric field to an electrorheological solution will cause the solution to solidify. By wrapping the patient's arm or leg with the liquid electrorheological solution and then applying an electric field, the solution solidifies and is used for fixation. It can be adapted to most patients and is highly practical. In addition, it is equipped with a disinfectant collection device, which avoids the waste disinfectant from contaminating the wound cleaning table and causing cross-infection. It greatly improves the work efficiency of medical staff and reduces the difficulty of their work.

[0005] While existing wound debridement devices can assist medical staff in performing debridement procedures, the process involves multiple steps. Cleaning the wound requires experienced physicians, while disinfection, cleaning, medication application, and drying require lower skill levels and can therefore be automated. Current devices still require multiple medical personnel to work together to complete the various steps, further increasing manpower waste and reducing efficiency. Therefore, we propose a new wound debridement device for surgical care. Summary of the Invention

Detailed Implementation

[0032] Example

[0033] Please see Figure 1-11 The present invention provides a technical solution:

[0034] A surgical debridement device includes a mounting frame 1 with a fixedly connected device box 2. The device box 2 contains multiple functional units to assist in patient debridement, thereby automating debridement care, reducing manpower and labor intensity for medical staff, and improving work efficiency. The device box 2 has an opening 3 on its surface, and a limb support device 4 and a shelf 5 are fixedly connected thereto. The limb support device 4 is located on one side of the opening 3. The limb support device 4 and the shelf 5 are vertically arranged, forming a debridement work area. The patient places their limb on the surface of the limb support device 4, allowing medical staff to clean the wound at this work area. Simultaneously, the surface of the shelf 5 is used to place medical equipment, further facilitating access and improving the efficiency of debridement. The equipment box 2 houses a motor A6, and a turntable 7 is mounted on the output shaft of motor A6. Multiple sets of movable function boxes 8 are mounted on the surface of the turntable 7, each containing a different functional unit. These movable function boxes 8 are arranged circumferentially on the surface of the turntable 7, enabling the device to assist in various debridement operations. Furthermore, the turntable 7 is rotated when motor A6 is activated, further controlling the position switching of the multiple sets of movable function boxes 8. This allows the movable function boxes 8 to push out the functional units to be used from the opening 3, further controlling the functional units to cover the limb placed on the surface of the limb support device 4, enabling different operations such as cleaning, disinfection, drying, and medication application on the patient's limb.

[0035] The limb support device 4 includes a support plate 401 fixedly connected to the surface of the equipment box 2. The upper surface of the support plate 401 is flush with the lower surface of the opening 3, allowing the patient's limb to be placed on the surface of the support plate 401. The movable functional box 8 can then drive the functional unit to cover the patient's limb, facilitating care of the patient's limb injury. The surface of the support plate 401 is provided with a V-shaped groove 402. A drainage hole 403 is located at the lowest point of the groove 402. A waste liquid tank 404 is fixedly connected to the lower surface of the support plate 401, and the drainage hole 403 and the waste liquid tank 404 are interconnected. This allows contaminants to fall onto the surface of the groove 402 during wound cleaning, and further facilitates the collection of contaminants and prevents leakage when the patient's limb wound is cleaned.

[0036] The support plate 401 has two sets of symmetrically distributed latches 405 on its surface. Each set of latches 405 has a pressure plate 406 hinged inside, and the pressure plate 406 contains a torsion spring. The torsion spring controls the relative rotation of the two pressure plates 406, further controlling the patient's limb after it is placed on the surface of the support plate 401. The two pressure plates 406 clamp and fix the patient's limb, preventing movement of the limb during debridement and subsequent care, thus avoiding errors in the debridement and care procedures and preventing further secondary injury to the patient. Furthermore, a protective pad 407 is fixedly connected to the surface of the pressure plate 406. The protective pad 407, by contacting the patient's limb surface, improves patient comfort, allowing the patient to maintain a fixed posture during debridement.

[0037] The surface of the turntable 7 is equipped with limiting slide rails 9. The movable function box 8 includes a box body 801 installed between the limiting slide rails 9. By sliding the box body 801 within the limiting slide rails 9, the movable function box 8 can be extended and retracted from the equipment box 2. This allows the functional units installed within the movable function box 8 to cover the patient's limb wound for wound care. Slide strips 802 are fixedly connected to both sides of the box body 801. The limiting slide rails 9 are arranged in four sets, symmetrically arranged in pairs. The slide strips 802 are appropriately inserted between two sets of limiting slide rails 9 on the same side, further enabling the box body 801 to slide stably between the limiting slide rails 9. Furthermore, the upper and lower surfaces of the slide bar 802 are provided with spherical limiting holes 803 that are linearly distributed at equal intervals. At the same time, ball bearings 804 are inserted into the spherical limiting holes 803. The ball bearings 804 are adapted to abut against the surface of the limiting slide rail 9, so that when the housing 801 slides between the limiting slide rails 9, the sliding friction force can be converted into rolling friction force through the ball bearings 804, which further improves the smoothness and stability of the sliding of the housing 801 and realizes the efficient operation of this device.

[0038] A mounting column 10 is fixedly connected to the upper surface of the turntable 7. The movable functional box 8 also includes a mounting plate 805 connected to the surface of the mounting column 10. The mounting plates 805 are arranged in two sets, one above the other. A vertically distributed lead screw A806 is inserted between the two sets of mounting plates 805. A matching slider 808 is mounted on the surface of the lead screw A806. A motor B807 is fixedly connected to the surface of the mounting plate 805. The output shaft of the motor B807 is connected to the lead screw A806. When the motor B807 is turned on, it drives the lead screw A806 to rotate, further controlling the slider 808 to slide linearly on the surface of the lead screw A806. A protrusion A809 is fixedly connected to the surface of the lead screw A806. A hinge shaft 810 is inserted inside the protrusion A809, and a connecting rod 811 is hinged to the hinge shaft 810. The other end of the connecting rod 811 is hinged to the protrusion B812 fixedly connected to the surface of the box 801 through the hinge shaft 810. Furthermore, when the slider 808 slides on the surface of the lead screw A806, it controls the connecting rod 811 to rotate, which in turn controls the connecting rod 811 to pull the housing 801 to slide between the limiting slide rails 9. When the motor A6 is turned on to drive the turntable 7 to rotate and controls the relative movable functional housing 8 and opening 3 to align, the housing 801 can automatically pass through the opening 3 and cover the patient's limb by controlling the sliding between the limiting slide rails 9, facilitating subsequent nursing care.

[0039] The functional unit 8 contains three functional modules: a cleaning and disinfection unit, a drying unit, and a medication application unit. The cleaning and disinfection unit cleans and disinfects the surface of the patient's limb wound, facilitating multiple wound cleanings by medical staff. This ensures the removal of necrotic and inflamed tissue, and after removal, the wound surface is disinfected to prevent infection. The drying unit quickly dries the wound surface after cleaning, promoting healing. The medication application unit applies medication to the wound surface to further aid healing and improve the overall effectiveness of the device. The cleaning, disinfection, drying, and medication application units can be used repeatedly in any order to accommodate complex wound cleaning procedures and enhance the overall cleaning effect.

[0040] The cleaning and disinfection unit includes a fixed base 11 and a motor C12 installed on the inner wall of the housing 801. A lead screw B13 is inserted inside the fixed base 11, and the output shaft of the motor C12 is connected to the lead screw B13. A matching slide A14 is mounted on the surface of the lead screw B13. A ring frame 15 is fixedly connected to the lower surface of the slide A14, and nozzles 16 distributed equidistantly are fixedly connected to the lower surface of the ring frame 15. After the cleaning water or disinfectant is delivered into the nozzles 16, it can be sprayed out through the nozzles 16 to clean and disinfect the surface of the patient's limb wound. When the housing 801 covers the patient's limb, the motor C12 drives the lead screw B13 to rotate, further controlling the slide A14 to slide on the surface of the lead screw B13. This allows the ring frame 15 to slide above the patient's limb surface, enabling the nozzles 16 to clean or disinfect wounds at any location on the patient's limb surface, further ensuring effective cleaning or disinfection of the patient's limb wound surface. Furthermore, the ring frame 15 is designed in a semi-circular shape, allowing for the cleaning and disinfection of wounds on different surfaces of the patient's limb. The cleaning and disinfection unit also includes a clean water tank 17 and a disinfectant tank 18 installed inside the housing 801. The clean water tank 17 and the disinfectant tank 18 are used to store cleaning water and disinfectant, respectively. Both the clean water tank 17 and the disinfectant tank 18 are connected to the nozzle 16 via a telescopic hose 19, further ensuring a continuous supply of cleaning water or disinfectant to the telescopic hose 19 during the sliding of the ring frame 15, thus ensuring the cleaning and disinfection of the wound surface of the patient's limb by the cleaning and disinfection unit.

[0041] The drying unit includes a heating lamp 20 installed inside the housing 801. After the drying unit is placed over the patient's limb wound, the heating lamp 20 is activated to dry the surface of the wound, further reducing surface moisture and achieving rapid drying after cleaning. Furthermore, after applying medication to the wound, drying the medication on the wound surface accelerates the drying efficiency of the ointment, increasing its adhesion to the skin and allowing it to remain more stably on the affected area, thus promoting drug absorption and therapeutic efficacy. Simultaneously, the ointment solidifies on the wound surface to form a protective layer, ensuring a seal around the wound and reducing the risk of external contamination and infection.

[0042] The medication application unit includes a medication box 21 mounted on the inner wall of the housing 801. A spray head 22 is mounted on the lower surface of the medication box 21, allowing the housing 801, after sliding to the surface of the patient's limb wound, to spray the medication from the medication box 21 through the spray head 22, thus controlling the application of the medication to the wound surface and achieving rapid application. The medication application unit also includes a motor D23 mounted on the inner wall of the housing 801. A lead screw C24 is fixedly connected to the output shaft of the motor D23, and a matching slide B25 is mounted on the surface of the lead screw C24. The slide B25 is T-shaped, with two symmetrically distributed vertical rods 26 inserted into its lower surface. A hinge block 27 is fixedly connected to the lower end of each set of vertical rods 26, and a mounting shaft 28 is inserted between the two sets of hinge blocks 27. Massage rollers 29 are fixedly connected to the surface of the mounting shaft 28. Simultaneously, a limiting plate 30 is fixedly connected to the upper surface of the vertical rod 26. A spring B31 is sleeved on the surface of the vertical rod 26. One end of the spring B31 is fixedly connected to the surface of the slide table B25, and the other end of the spring B31 is fixedly connected to the surface of the limiting plate 30. This further ensures that the massage roller 29 is always pushed downwards under the elastic force of the spring B31. Furthermore, after the housing 801 containing the medication application unit slides above the patient's limb wound, the massage roller 29 is in contact with the surface of the patient's limb wound. Under the elastic force of the spring B31, it remains in contact with the surface of the patient's limb wound. This further ensures that when the motor D23 drives the lead screw C24 to rotate, it controls the slide table B25 to slide linearly on the surface of the lead screw C24, further controlling the massage roller 29 to contact the surface of the patient's limb wound. During rotation, the medication can be evenly applied to the surface of the patient's limb wound, achieving rapid medication application.

[0043] An annular limiting rail 32 is fixedly connected to the inner wall of the equipment box 2. The annular limiting rail 32 and the limiting slide rail 9 are flush, and the front end of the limiting slide rail 9 is tangent to the annular limiting rail 32, which further allows the box body 801 to slide from the surface of the limiting slide rail 9 to the surface of the annular limiting rail 32, ensuring the stability of the box body 801 sliding out of the opening 3.

[0044] The storage platform 5 includes a platform 501 fixedly connected to the outer surface of the equipment box 2. A cleaning tank 502 is fixedly connected to the lower surface of the platform 501. A cleaning groove 503 is provided on the surface of the platform 501 and communicates with the inside of the cleaning tank 502. The platform 501 is used to place medical equipment to be used, and after use, the medical equipment can be placed into the cleaning tank 502 through the cleaning groove 503 for convenient subsequent cleaning. The storage platform 5 also includes a sleeve 504 fixedly connected to the inner wall of the equipment box 2, with one end of the sleeve 504 extending into the interior of the equipment box 2. A sliding rod 505 is inserted inside the sleeve 504, and a rotating block 33 is fixedly connected to the output shaft of the motor A6. A rotating rod 34 is fixedly connected to the surface of the rotating block 33, and the rotating rod 34 and the sliding rod 505 are horizontally distributed. The end of the slide rod 505 facing the rotating rod 34 is set with an inclined surface, which further causes the rotating rod 34 to periodically abut against the surface of the slide rod 505 during rotation, further pushing the slide rod 505 to slide within the sleeve 504. A spring A506 is fixedly connected to one end of the slide rod 505 inserted inside the sleeve 504, and the other end of the spring A506 is fixedly connected to the inner wall of the sleeve 504. Therefore, the slide rod 505 is always pushed out of the sleeve 504 under the elastic force of the spring A506. This further ensures that when the rotating rod 34 pushes the slide rod 505, the slide rod 505 will quickly return to its original position under the elastic force of the spring A506, further causing the slide rod 505 to slide back and forth within the sleeve 504. Furthermore, the two sides of the sleeve 504 are provided with limiting grooves 507, and the surface of the slide rod 505 is provided with limiting protrusions 508. The limiting protrusions 508 are inserted into the limiting grooves 507 in a matching manner, further ensuring the smoothness and stability of the slide rod 505 in the sleeve 504.

[0045] A push rod A509 is fixedly connected to one end of the slide rod 505 inserted into the sleeve 504. The other end of the push rod A509 extends into the interior of the cleaning tank 502. A U-shaped tube 511 is fixedly connected inside the cleaning tank 502. A sealing piston A512 is fixedly connected to one end of the push rod A509 inserted into the U-shaped tube 511. A cleaning plate A510 is fixedly connected to the surface of the push rod A509, located on one side of the U-shaped tube 511. A sealing piston B513 is inserted into the other end of the U-shaped tube 511. A push rod B514 is fixedly connected to the surface of the sealing piston B513. A cleaning plate B515 is fixedly connected to the surface of the push rod B514. The cleaning plates B515 and A510 are parallel to each other. The cleaning tank 503 is located between the cleaning plates A510 and B515. After the used medical device is inserted into the cleaning box 502 through the cleaning tank 503, the motor A6, while driving the movable functional box 8 for adjustment, controls the push rod A509 to push the cleaning plate A510 to slide within the cleaning box 502. Simultaneously, the push rod A509 drives the sealing piston A512 to slide within the U-shaped tube 511, drawing compressed air from inside the U-shaped tube 511. This causes the sealing piston B513, under negative pressure or air pressure, to synchronously drive the push rod B514 to slide within the U-shaped tube 511, further controlling the synchronous sliding of the cleaning plates B515 and A510. When the used medical device is inserted between the cleaning plates B515 and A510, the sliding motion of the cleaning plates cleans the surface of the medical device, achieving rapid cleaning and facilitating subsequent wound cleaning.
