Therefore, they cannot be understood as limitations on the present invention.

[0030] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Embodiment: A surgical debridement device, such as Figure 1-Figure 5 and Fig.11 As shown, including: The gripping frame 1 is a frame body with a gripping rod for the operator to grip and operate. A vertical plate 11 is symmetrically arranged at the top middle of the gripping frame 1. The rotating seat 2 is hingedly disposed between the two vertical plates 11, allowing the rotating seat 2 to realize a rotating operation; The flip plate 3 is fixedly connected to the front end of the rotating seat 2 so that the flip plate 3 can rotate synchronously with the rotating seat 2. The left and right sides of the front end of the flip plate 3 are fixedly provided with mounting plates 31. In the initial state, the rotating seat 2 and the flip plate 3 are both located at the front side of the holding frame 1, so that the mounting plate 31 as a whole tends to extend forward; The debridement mechanism 4 for cleaning wounds is arranged on the mounting plate 31. The debridement mechanism 4 includes a double-axis motor 41 fixedly mounted on the front side of the flip plate 3. A rotating cylinder 42 rotates in each of the two mounting plates 31. The rotating cylinder 42 is connected to the output end on the same side of the double-axis motor 41, so that the double-axis motor 41 can drive the rotating cylinders 42 on both sides to operate synchronously. A group of bearings 43 is arranged on the front side of the mounting plate 31. The number of a group of bearings 43 is two. The two bearings 43 in the same group are arranged at intervals on the left and right. A pulley group 44 is arranged between the rotating cylinder 42 and the bearing 43 on the same side. The front pulley of the pulley group 44 is located on the inner ring of the bearing 43. An internal The hollow straight cylinder 45 allows the straight cylinder 45 to be embedded in the inner ring parts of the bearings 43 on both sides. From then on, when the dual-axis motor 41 is started, the rotating cylinders 42 on both sides are driven to rotate, and then the power is transmitted to the bearings 43 through the pulley set 44, thereby driving the straight cylinder 45 embedded therein to rotate accordingly, so that under the lubrication of the bearings 44, the rotational movement of the straight cylinder 45 is made more stable and smooth. A bidirectional screw rod 46 rotates between the left and right ends of the straight cylinder 45, and the ends of the bidirectional screw rod 46 are placed outside the straight cylinder 45, and the left and right ends of the bidirectional screw rod 46 are fixedly provided with a clamping frame 47 that is clamped with the pulley of the pulley set 44 on the same side, which is used to fix the position of the bidirectional screw rod 46 after the position adjustment. For details, see Figure 5, it can be seen that the positioning frame 47 is a frame body with symmetrical extension ends, and the outward side of the extension ends on both sides are provided with protrusions. Under the restriction of the protrusions on both sides, the initial diameter of the positioning frame 47 is larger than the inner diameter of the corresponding pulley. In order to realize the clamping action of the positioning frame 47, the extension end of the positioning frame 47 is made of a metal material with shape memory, so that the diameter of the positioning frame 47 is reduced by pinching the extension end to deform and smoothly extend into the interior of the pulley. Under the action of the metal memory, the extension end of the positioning frame 47 will return to its original state, and then the protrusion of the extension end will be reset and snapped into the corresponding pulley, so as to fix the position of the bidirectional screw rod 46. There are movable seats 48 sliding symmetrically on the straight cylinder 45 on the left and right. The two movable seats 48 are respectively threadedly connected to one side of the bidirectional screw rod 46. The surfaces of the movable seats 48 on both sides are provided with protruding ends at intervals along the circumferential direction, and a brush plate 49 for brushing the wound is clamped between the two opposite protruding ends on the left and right.

[0032] Specifically, the brush plate 49 is composed of a deformable metal base plate and soft bristles arranged on the metal base plate. By rotating the bidirectional screw 46, the movable seats 48 on both sides can be driven to slide towards or away from each other, forcing the metal base plate to deform accordingly. When moving towards each other, the metal base plate is squeezed and then bulges, and the metal base plate becomes shorter, which reduces the use area of ​​the soft brush plate and makes the area covered by the soft bristles more concentrated, so as to be suitable for brushing smaller wounds; conversely, when the movable seats 48 on both sides move away from each other, the metal base plate of the brush plate 49 is pulled and then stretched, and the length of the metal base plate is extended, so that the soft bristles on it can be unfolded, so that the brush plate 49 can cover a larger area of ​​wounds for brushing larger wounds.

[0033] Therefore, it can be seen from the above that through the setting of the adjustable brush plate 49, the device as a whole can be adjusted to adapt to different wound sizes, so as to provide adaptive debridement treatment for different wounds. Combined with the portable design of the holding frame 1, it not only improves the convenience and simplicity of operation, but also effectively enhances the overall treatment effect, thereby ensuring the patient's wound treatment effect.

[0034] like Figure 1 , Figure 6-Figure 8 , Fig.11 and Fig.12As shown, a disinfection mechanism 5 for disinfecting wounds is arranged on the holding frame 1, and the disinfection mechanism 5 includes an infusion tube 51 arranged in the holding frame 1, and the infusion tube 51 is equipped with a power source (a small pump body) to provide the power required for subsequent infusion, and the two ends of the infusion tube 51 pass through and are exposed at the bottom and front end of the holding frame 1 respectively, and the left and right sides of the front end of the infusion tube 51 are connected with injection tubes 52; two groups of guide plates 53 are symmetrically arranged at the front end of the flip plate 3, and the two guide plates 53 of the same group are arranged at an interval up and down, and a nozzle with the same number of nozzles as the injection tube 52 is hingedly arranged between the guide plates 53 of the same group. A drainage frame 54 is adapted to the amount, and a torsion spring (not shown in the figure) is arranged between the drainage frame 54 and the corresponding guide plate 53. The setting of the torsion spring can ensure the reset operation of the drainage frame 54 after rotation. Concave grooves for accommodating the drainage frame 54 on the same side are respectively opened on the left and right sides of the holding frame 1, so that the drainage frame 54 can be completely embedded in the concave groove on the same side after closing, thereby reducing unnecessary usage area. The injection pipe 52 extends into the drainage frame 54 on the same side and the nozzles of the two are aligned accordingly. The drainage frame 54 is rotated to make the corresponding injection pipe 52 bend or unfold, so as to control the overall spraying effect.

[0035] like Figure 6-Figure 8 , Fig.11 and Fig.12 As shown, the disinfection mechanism 5 also includes a drawstring 55 arranged at the hinge of the drainage frame 54, and the drawstring 55 slides through the holding frame 1, and arc grooves 21 are opened on both sides of the rotating seat 2. The arc groove 21 is located at the rear lower side of the rotating seat 2, and the opening of the arc groove 21 forms an angle of 90 degrees with the hinge center of the rotating seat 2. The end of the drawstring 55 is slidably embedded in the arc groove 21 on the same side; for details, see Figure 8 and Fig.12 , Figure 8 is the initial state of the pull rope 55, Fig.12 The state after the pull rope 55 is pulled is shown. Under the restriction of the arc groove 21, the pull rope 55 can pull the corresponding drainage frame 54 to expand by 90 degrees, thereby extending the spraying area of ​​the disinfectant and ensuring the required disinfection effect.

[0036] like Figure 1 , Fig. 9 and Fig.10As shown, a flushing mechanism 6 for flushing the wound is provided at the front end of the flip plate 3, and the flushing mechanism 6 includes a shunt tube 61 arranged at the bottom of the holding frame 1, and the shunt tube 61 is equipped with a power source (a small pump body) for conveying a cleaning agent (physiological saline or clean water), and the shunt tube 61 has two tube heads, and the tube ends of the shunt tube 61 pass through the holding frame 1 and penetrate the flip plate 3, so that the tube head position of the shunt tube 61 is adjacent to the extension plate 3, and a transverse plate 62 is provided at the front end of the flip plate 3, and a sliding frame 63 is slidably provided on the transverse plate 62, and the sliding frame 63 is slidable in the up and down directions, and a liquid spraying tube 64 is provided on the left and right sides of the sliding frame 63 at intervals, and the liquid spraying tube 64 is respectively connected to one side of the tube head of the shunt tube 61, and an extension frame 65 slidably matched with the transverse plate 62 is provided on the left and right sides of the sliding frame 63, so as to extend the moving path of the sliding frame 63, so that the moving range of the sliding frame 63 is wider.

[0037] like Fig.10 As shown, the flushing mechanism 6 also includes two groups of guide rods 66 respectively arranged on the left and right sides of the cross plate 62, and a card plate 67 is slidably inserted between the guide rods 66 of the same group. The upper and lower end surfaces of the card plate 67 are both provided with inclined surfaces, and a spring is arranged between the guide rods 66 and the cross plate 62 to provide the necessary elastic support for the movement of the card plate 67. The extension frame 65 is symmetrically provided with card slots 651 which are both fitted with the card plate 67 on the same side to fix the position of the extension frame 65 after displacement. By pushing the extension frame 65 up and down, the inclined surface of the card plate 67 can be squeezed, thereby pushing the card plate 67 to move. The spring conforms to the deformation, and when the card plate 67 is close to the card slot 651, under the resetting action of the spring, the card plate 67 is carded into the card slot 651 and the card operation is realized.

[0038] Specifically, due to the extension of the length of the extension frame 65, the span of the sliding frame 63 and its upper parts increases accordingly, thereby presenting the flushing effect at different positions. When the card plate 67 is engaged with the lower slot 651, the spray pipe 64 is flush with the brush plate 49, so that the flushing agent is sprayed toward the brush plate 49 to soak the soft bristles and cooperate with the debridement operation to flush and guide the discharge of impurities in the wound; conversely, when the card plate 67 is engaged with the upper slot 651, the spray pipe 64 is located in a lower position, so that the flushing agent is sprayed toward the lower part of the wound, thereby effectively cleaning the edge of the wound.

[0039] like Figure 1 and Fig.11 As shown, it also includes a collecting frame 7 arranged at the rear end of the holding frame 1 to accommodate the brush plate 49 after the flip position for placement and subsequent cleaning processing.

[0040] like Figure 1 and Fig.11As shown, it also includes a protective frame 8 symmetrically hinged on the left and right sides of the holding frame 1. The protective frame 8 is adapted to the recessed groove on the same side to shield and protect the drainage frame 54 after closing. Magnets 81 that are magnetically compatible with the holding frame 1 are also fixed at intervals on the protective frame 8 to fix the position of the protective frame 8 after closing.

[0041] like Figure 2 and Fig.11 As shown, it also includes a positioning frame 32 slidably arranged on the flip plate 3, and the positioning frame 32 is plugged into and matched with the holding frame 1 to fix the position of the flip plate 3 in different use states.

[0042] First, place the patient's injured limb on the debridement table, then the operator holds the holding frame 1 to ensure that the flip plate 3 is in the forward flip position, that is, the brush plate 49 is also at the front end, and then pushes the positioning frame 32 to insert it between the flip plate 3 and the holding frame 1 to fix the positions of the two, and then adjusts the width of the brush plate 49 according to the size of the wound, first pinch the positioning frames 47 on both sides to make the positioning frames 47 loosen the pulleys of the pulley group 44, release the locking restriction on the bidirectional screw rod 46, and then rotate the bidirectional screw rod 46. As the bidirectional screw rod 46 rotates, the corresponding Under the action of the thread, the corresponding moving seat 48 follows the thread trend and slides along the straight tube 45, that is, the moving seats 48 on both sides move closer to or away from each other, forcing the brush plate 49 to be squeezed and bulged, or stretched and expanded, so as to achieve the effect of width adjustment. After the state of the brush plate 49 is adjusted, the positioning frames 47 on both sides can be reinserted into the corresponding pulleys to lock the position state of the bidirectional screw rod 46; then the ends of the infusion tube 51 and the shunt tube 61 are respectively connected to the required disinfectant and flushing agent (physiological saline or clean water) for use. , then the wound cleaning treatment of the patient begins. First, the double-axis motor 41 is started. Driven by the double-axis motor 41, the connected rotating cylinder 42 is driven to rotate. As the rotating cylinder 42 rotates, the corresponding pulley group 44 and the bearing 43 are synchronously driven to rotate. Under the rotation of the bearing 43, the straight cylinder 45 and its upper parts are driven to rotate together, so that the brush plate 49 can rotate and operate in coordination with the flushing mechanism 6. At this time, the nozzle position of the spray pipe 64 is directly opposite to the brush plate 49, so that the flushing agent (physiological saline or clean water) transported by the shunt pipe 61 is sprayed toward the brush plate 49 through the spray pipe 64. The brush bristles of each rotating brush plate 49 are then wetted by the flushing agent, and the wound is scrubbed with the soaked brush plate 49, so that foreign matter (such as dirt, debris, etc.), necrotic tissue and pollutants in the wound are discharged along with the flushing water, thereby cleaning the wound. After the wound is cleaned, the extension frame 65 is pressed down, and then the sliding frame 63 and the spray pipe 64 are moved down, so that there is a gap between the nozzle of the spray pipe 64 and the brush plate 49, and the flushing agent is sprayed to the edge of the wound through the spray pipe 64 by utilizing the height difference, so as to flush the edge of the wound; After the wound is flushed, the operation of the debridement mechanism 4 and the flushing mechanism 6 is stopped, the protection frames 8 on both sides are rotated to open, and then the positioning frame 32 is pushed open to make it out of contact with the holding frame 1, so that the flip plate 3 is released from the restriction, and then the flip plate 3 is flipped backward, and the flip plate 3 together with its upper parts are transferred backward until the flip plate 3 is in contact with the rear side of the holding frame 1, and the brush plate 49 is placed in the collection frame 7, and then the position between the flip plate 3 and the holding frame 1 can be fixed by the positioning frame 32. At the same time, with the rotation of the flip plate 3, the rotating seat 2 connected thereto is synchronously rotated between the vertical plates 11. When the rotating seat 2 rotates 90 degrees, the arc groove 21 rotates from the initial rear lower position to the front lower position, so that the pull rope 55 can be fixed without being pulled. Under this circumstance, the rope end is slid along the arc groove 21 whose position changes, and then the rope end of the pull rope 55 is changed from the initial front end to the rear end position. As the flip plate 3 flips ninety degrees again, that is, the rotating seat 2 operates synchronously, the arc groove 21 moves synchronously with the operation of the rotating seat 2, and pulls the rope end at the rear end, thereby pulling the pull rope 55 backward. As the pull rope 55 is pulled backward, the drainage frame 54 connected to it rotates along the guide plate 53 until the flip plate 3 is completely attached to the top rear side of the holding frame 1, the drainage frames 54 on both sides are unfolded, and the injection tube 52 is also extended and unfolded. Then the disinfectant can be transported through the infusion tube 51, so that the disinfectant is sprayed through the injection tube 52 to disinfect the wound, thereby completing the overall debridement operation.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
