Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-7 This utility model discloses a traction device for wound repair with disinfection function, including a support plate 1. Two T-shaped plates 2 are fixed to the top of the support plate 1. Two rotating shafts 3 are rotatably connected to the side walls of the T-shaped plates 2 through bearings. Traction clamps 4 are fixed to the surfaces of the two rotating shafts 3 respectively. Gears 5 are fixed to the surfaces of the rotating shafts 3 respectively. The two corresponding gears 5 are meshed with each other. A motor 12 is fixed to one side wall of one of the T-shaped plates 2. The output end of the motor 12 is fixedly connected to one end of one of the rotating shafts 3. A support platform 6 is attached to the top of the two T-shaped plates 2. An adjustment mechanism 7 for adjusting the height of the support platform 6 is provided on the top of the support plate 1. A protective box 8 is provided outside the support plate 1. A cover plate 9 is hinged to the top of the protective box 8. An ultraviolet disinfection lamp 10 is installed on the inner wall of the top of the cover plate 9. A lifting mechanism 11 for pushing out the traction clamps 4 is provided inside the protective box 8.

[0027] Specifically, the adjustment mechanism 7 includes a mounting base 701 fixed to the top of the support plate 1. A guide seat 702 is fixed to the top of the mounting base 701. Two lead screws 703 are rotatably connected to the guide seat 702 via bearings. The threads on the surfaces of the two lead screws 703 are opposite. A dual-axis motor 704 is fixed to the guide seat 702. One end of each of the two lead screws 703 is fixedly connected to the corresponding output end of the dual-axis motor 704. Each lead screw 703 has a moving block 705 threadedly connected to its surface thread. Two connecting plates 706 are rotatably connected to the mounting base 701 via pins. Each connecting plate 706 is rotatably connected to an adjustment plate 707 via pins. The top ends of the adjustment plates 707 are rotatably connected to the bottom of the support platform 6 via pins. The bottom ends of the two adjustment plates 707 are rotatably connected to the corresponding moving blocks 705 via pins.

[0028] In this embodiment, during use, the dual-axis motor 704 with self-locking function can be started to drive the two lead screws 703 with opposite threads to rotate synchronously. After the two lead screws 703 rotate, they will drive the two moving blocks 705 to move away from each other. After the moving blocks 705 move, with the cooperation of the connecting plate 706 and the adjusting plate 707, the support platform 6 can be moved upward to adjust the wound position to a suitable height, so that the wound position can be accurately clamped and pulled by the traction clamp 4.

[0029] Specifically, the top of the support plate 1 is fixed with a slide rail 708 that is compatible with the moving block 705, and both moving blocks 705 slide on the slide rail 708.

[0030] In this embodiment, the slide rail 708 can guide and limit the two moving blocks 705, so that when the lead screw 703 rotates, the moving blocks 705 will not rotate synchronously with it.

[0031] Specifically, the lifting mechanism 11 includes four square guide tubes 1101 fixed inside the protective box 8. Each square guide tube 1101 is slidably connected to a lifting rod 1102. The top of each lifting rod 1102 is fixedly connected to the bottom of the support plate 1. A bearing seat 1103 is fixed between the four lifting rods 1102. Two side plates 1104 are fixed to the top of the bearing seat 1103. Two rotating rods 1105 are rotatably connected between the two side plates 1104 through bearings. Two actuating rods 1106 are fixed to the surface of each rotating rod 1105. The actuating rods 1106 are respectively limited and movably connected to the corresponding lifting rods 1102.

[0032] In this embodiment, when in use, the two rotating rods 1105 are rotated, which drives the actuating rods 1106 on both sides to rotate synchronously in opposite directions. After the actuating rods 1106 rotate, they drive the corresponding lifting rods 1102 to move upward. At this time, the support plate 1 can be driven to move upward, and the support platform 6 and the traction clamp 4 and other components can be lifted to the outside of the protective box 8 for use. The square guide tube 1101 can support and guide the lifting rods 1102.

[0033] Specifically, a U-shaped plate 1107 is fixed to the top of the bearing seat 1103. A worm gear 1108 is rotatably connected to the top of the U-shaped plate 1107 via a bearing. The bottom end of the worm gear 1108 is rotatably connected to the bearing seat 1103 via a bearing. Worm wheels 1109 are fixed to the surface of the rotating rod 1105. The worm wheels 1109 are meshed with the worm gear 1108. A second motor 1110 is fixed to the top of the U-shaped plate 1107. The output end of the second motor 1110 is fixedly connected to the top end of the worm gear 1108.

[0034] In this embodiment, starting the self-locking motor 1110 can drive the worm 1108 to rotate. After the worm 1108 rotates, it can drive the two worm wheels 1109 to rotate synchronously in opposite directions. Therefore, it can synchronously drive the two rotating rods 1105 to rotate. After the worm 1108 and the worm wheels 1109 drive the two rotating rods 1105 to rotate, the two have a self-locking function, so that when the two rotating rods 1105 rotate, it can further prevent the situation from loosening.

[0035] Specifically, a sponge pad 13 is fixed to the top of the support platform 6, and four telescopic sleeves 14 are fixed to the bottom of the support platform 6. The bottom ends of the telescopic sleeves 14 are all fixedly connected to the support plate 1.

[0036] In this embodiment, the sponge pad 13 makes it more comfortable for the patient to place their limbs on top of the support platform 6, while the telescopic sleeve 14 provides auxiliary support for the support platform 6, making it more stable when the support platform 6 moves up and down.

[0037] Specifically, a circular ventilation slot 15 is provided on the back of the protective box 8, and a circular filter screen 16 is fixed inside the circular ventilation slot 15.

[0038] In this embodiment, the circular ventilation slot 15 can be used to ventilate and dissipate heat for the lifting mechanism 11 inside the protective box 8, while the circular filter 16 can prevent dust and other impurities in the outside air from entering the interior of the protective box 8 through the circular ventilation slot 15.

[0039] Specifically, each of the surfaces of the traction clamp 4 is fixed with a U-shaped anti-slip pad 17, which is made of silicone.

[0040] In this embodiment, the U-shaped anti-slip pad 17 can increase the friction between the traction clip 4 and the skin surface, so that the traction clip 4 can play an anti-slip role when it clamps and pulls the skin wound.

[0041] Specifically, the outer wall of the protective box 8 is fixed with two handle plates 18.

[0042] In this implementation plan, the handrail 18 is designed to facilitate close-range movement and handling of the protective box 8 by medical staff.

[0043] Specifically, gears 5 are fixed on the surface of the rotating shaft 3, and two corresponding gears 5 are meshed and connected to each other.

[0044] In this embodiment, by providing gears 5 on the surfaces of all four rotating shafts 3, the four rotating shafts 3 can be driven to rotate simultaneously under the drive of a motor 12, thereby enabling the two traction clamps 4 to rotate synchronously in opposite directions.

[0045] The working principle and usage process of this utility model are as follows: In use, after opening the cover plate 9, the lifting mechanism 11 can be activated to push the support plate 1 upwards. After the support plate 1 moves upwards, it will push the support platform 6 and the traction clamp 4 into the protective box 8. Then, the patient's limb can be placed on top of the support platform 6. To facilitate the protection of the surface of the support platform 6, a disposable protective pad can be placed on top. Due to the different thicknesses and body shapes of the patient's arms and legs, the required traction height for the wound varies. To facilitate precise traction of the wound by the traction clamp 4, the height of the support platform 6 can be adjusted by operating the adjustment mechanism 7. After adjustment, the self-locking motor 12 can be activated to drive one of the rotating shafts. 3. With the cooperation of the four gears 5, the traction clamps 4 on both sides can rotate synchronously in opposite directions. After the two traction clamps 4 rotate synchronously in opposite directions, they will squeeze the skin on both sides of the wound, thereby achieving the traction effect. After use, the traction clamps 4 and other parts can be wiped and disinfected. Then, the lifting mechanism 11 is started to move the support plate 1 down, so that the used traction clamps 4 can be stored in the protective box 8 for protection. After the cover plate 9 is closed with the protective box 8, the support platform 6 and traction clamps 4 and other parts can be continuously sterilized and disinfected under the action of the ultraviolet disinfection lamp 10 for the next use. The protective box 8 and the cover plate 9 are fixed by two sets of spring buckles, which are not shown in the figure.

[0046] In summary, this wound repair traction device with disinfection function solves the problems of current skin traction devices being unstable and the use of bone screws causing secondary skin damage to patients.
