[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 As shown, this utility model provides a handheld rapid surface skin debridement device, including a fixing plate 1. Multiple fixing sleeves 21 are fixedly installed inside the fixing plate 1. Multiple square grooves 4 are formed on the outer side of each fixing sleeve 21. A reinforcing ring 2 is slidably installed inside the fixing sleeve 21. Buckles 3 are fixedly installed on both sides of the bottom surface of the reinforcing ring 2, and the buckles 3 engage with the square grooves 4. A first tension rope 9 is fixedly installed inside the buckles 3, and the first tension rope 9 passes through the reinforcing ring 2. A connecting shaft 5 is fixedly installed on the bottom surface of the reinforcing ring 2. The bottom of the connecting shaft 5 is fixed... The device is equipped with a nail head 6, and metal hooks 7 are fixed on both sides of the nail head 6. Pushing the bottom end of the two side buckles 3 or pulling the first tension rope 9 will cause the buckles 3 to lose contact with the square groove 4. At this time, the connecting shaft 5 can slide inside the fixing sleeve 21, thereby adjusting the height of the bottom nail head 6 and metal hooks 7 to adapt to the position of the patient's wound. Then, the skin or scab at the patient's wound site can be cleaned by the nail head 6 and metal hooks 7, which facilitates subsequent examination, disinfection and medication.

[0023] Specifically, a linear bearing 8 is fixedly installed on the bottom inner side of the fixed sleeve 21, and the connecting shaft 5 slides inside the linear bearing 8. The linear bearing 8 is mainly used to reinforce the connecting shaft 5 here, and at the same time increase the smoothness of the sliding of the connecting shaft 5.

[0024] Furthermore, threaded sleeves 10 are fixedly installed on both sides of the bottom surface of the fixing plate 1, and the threaded sleeves 10 are internally threaded with threaded shafts 11. Since most human skin has a certain curvature, the height of the threaded shafts 11 can be adjusted to adapt to the curvature of the skin.

[0025] Furthermore, a connecting sleeve 12 is fixedly provided at the bottom of the threaded shaft 11, and a ball bearing 13 is rotatably provided on the inner side of the bottom of the connecting sleeve 12. The ball bearing 13 can reduce the friction when the device slides.

[0026] It is worth noting that a limiting shaft 17 is fixedly installed on the inner bottom of the threaded sleeve 10, and a spring 16 is sleeved on the outer side of the limiting shaft 17. One side of the spring 16 is fixedly connected to the threaded sleeve 10, and a locking block 15 is fixedly connected to the other side of the spring 16. The locking block 15 is slidably connected to the limiting shaft 17. A straight shaft 14 is fitted inside the locking block 15 and is fixedly connected to the threaded shaft 11. When the straight shaft 14 moves the position of the locking block 15, the spring 16 will pop out the locking block 15 to lock the straight shaft 14, thereby preventing the threaded shaft 11 from being accidentally unscrewed during subsequent operations.

[0027] It is worth noting that a second tension rope 18 is fixedly installed on the outside of the locking block 15, and the second tension rope 18 passes through the threaded sleeve 10. The threaded sleeve 10 can prevent the locking block 15 from popping out too much, and pulling the second tension rope 18 will also drive the locking block 15 to move backward, thereby retracting the threaded shaft 11.

[0028] It is worth mentioning that a connecting rod 19 is fixedly installed on the top outer side of the fixation plate 1, and a handle 20 is fixedly installed on the outer side of the connecting rod 19. Medical staff can hold the handle 20 and pull the fixation plate 1 through the connecting rod 19, which makes it more convenient for medical staff to clean wounds.

[0029] Among them, spring 16 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle:

[0031] When using the handheld rapid surface skin debridement device, firstly, adjust the length of the threaded shaft 11 according to the location of the patient's wound. Rotating the threaded shaft 11 via the connecting sleeve 12 causes the threaded shaft 11 to move the ball bearing 13 downwards, ensuring it is in close contact with the patient's skin. This also increases the smoothness of the device's overall movement. To prevent medical personnel from completely unscrewing the threaded shaft 11, a locking block 15 is installed inside the threaded sleeve 10. When the top straight shaft 14 of the threaded shaft 11 is screwed to the position of the locking block 15, the locking block 15 is ejected by the spring 16 outside the limiting shaft 17, thus locking the threaded shaft 11 and preventing it from being unscrewed. Pulling the second tension rope 18 causes the locking block 15 to move backward, allowing the threaded shaft 11 to be retracted. After adjusting the length of the threaded shaft 11, adjust the length of the connecting shaft 5 by pushing the latches 3 on both sides. The latches 3 disengage from the square groove 4. When there is obstruction, the length of the connecting shaft 5 can be adjusted. The linear bearing 8 on the inner side of the bottom of the fixing sleeve 21 is to make the sliding of the connecting shaft 5 smoother, while the first tension rope 9 prevents the connecting shaft 5 from sliding directly out of the fixing sleeve 21. At the same time, pulling the first tension rope 9 will drive the bottom of the buckle 3 to move inward. At this time, the length of the connecting shaft 5 can also be adjusted. The reinforcing ring 2 is used to reinforce the top of the connecting shaft 5 and fix the buckle 3. Then, the medical staff holds the handle 20 and pulls the connecting rod 19. The connecting rod 19 drives the fixing plate 1 and its related parts to move. At the same time, the nail head 6 and the metal hook 7 will scrape off the skin on the surface of the patient's wound. This utility model can scrape off the skin or scab of the wound, thereby speeding up the cleaning efficiency of the wound and making it easier for medical staff to change dressings, cut off, etc., and avoid more serious consequences of the wound due to slow wound treatment.
