Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of surgical equipment and instruments, and specifically to a flexible clamping device for limb wound repair. Background Art
[0002] A wound is the damage caused to normal skin (tissue) by external injuring factors such as surgical operations, external forces, heat, electric current, chemical substances, low temperature, and internal factors within the body such as local blood supply disorders. It is often accompanied by the destruction of skin integrity and the loss of a certain amount of normal tissue. At the same time, the normal functions of the skin are impaired. It is also called a wound or trauma. Wound repair is the same as wound repair. The application of flexible clamping technology in the medical field is mainly reflected in its ability to provide a gentle and adaptable clamping force, which is crucial for delicate medical operations without damaging tissues. For example, during the recuperation of orthopedic trauma or the repair of limb wounds, flexible clamping technology can ensure gentle contact between surgical instruments or repair materials and damaged tissues, thus avoiding secondary injuries caused by excessive clamping.
[0003] Currently, the wound clamping devices widely used clinically have technical limitations. The static clamping structure is difficult to adapt to the diameter changes during the dynamic healing process of the limbs, resulting in the need for most patients to make mid-course adjustments. At the same time, when applying medicine to the wound, the clamp needs to be removed before applying the medicine. Removing the clamp when the wound has not healed easily increases the risk of infection and is not conducive to the recovery of patients. Therefore, we propose a flexible clamping device for limb wound repair. Summary of the Invention

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0017] Embodiment 1: As Figures 1-9As shown in the figure, a flexible clamping device for limb wound repair in the figure includes a right bracket 1, and a left bracket 2 is detachably provided on one side of the right bracket 1. It further includes: a jacket 13 installed on the right bracket 1 and the left bracket 2. The jacket 13 includes a base layer 31, and the base layer 31 is made of a material with good flexibility and biocompatibility, such as polyurethane elastomer. This material can conform to the surface of the limb, providing a stable support foundation for the entire jacket 13, and at the same time being non-irritating to the skin, reducing the discomfort caused by contact. On one side of the base layer 31, there is a functional layer 32. A hydrogel composite film (PVA / PEG cross-linking density 85%) and a shape memory alloy woven mesh (wire diameter 0.2mm, weaving angle 55°) together constitute the functional layer 32. The hydrogel composite film has excellent water absorption and water retention properties, can absorb wound exudate, maintain a moist environment for the wound, and is conducive to wound healing; in practical applications, when the jacket 13 is installed on the limb, with the effect of the human body temperature, the shape memory alloy woven mesh can gradually return to the shape that conforms to the limb, providing uniform pressure, promoting blood circulation, and accelerating wound repair; outside the functional layer 32, there is a surface layer 33, and ventilation holes 39 are evenly opened above the surface layer 33. The surface layer 33 has good air permeability and waterproofness. The design of the ventilation holes 39 enables the wound to exchange gas with the outside world, preventing bacteria from growing due to damp and airtight conditions. At the same time, the silicone rubber material is soft and durable, which can effectively protect the wound from secondary external damage. Inside the jacket 13, sensors 37 are evenly arranged in an array, and the optimal clamping force distribution is calculated through the Hopfield neural network algorithm. The sensors 37 can dynamically adjust the clamping force according to the needs of different parts of the limb, ensuring that the most suitable pressure environment is provided for the wound without affecting blood circulation, promoting healing. On the right bracket 1 and the left bracket 2, an adjusting component 3 is installed. The adjusting component 3 is used to adjust the size of the jacket 13; and a medicine adding mechanism 4 installed on the jacket 13, and the medicine adding mechanism 4 is used to apply medicine to the affected area; and a quick-release component 5 installed on the right bracket 1 and the left bracket 2, and the quick-release component 5 is used to quickly connect the right bracket 1 and the left bracket 2.
[0018] Further, please refer to Figure 1 and Figure 6 , the adjusting component 3 includes connecting rods 6 uniformly and fixedly connected to the right bracket 1 and the left bracket 2. Outside two of the connecting rods 6, a driving motor 38 is installed. The driving motor 38 serves as a power source. The output shaft of the driving motor 38 is fixedly connected to a driving wheel 7 through a coupling. Outside both of the driving wheels 7, there are belts 8. Inside one end of the two belts 8 away from the driving wheels 7, there are driven wheels 9. The belts 8 play a role in power transmission, transmitting the rotational motion of the driving wheel 7 to the driven wheel 9. Driven by the belts 8, the driven wheel 9 rotates synchronously with the driving wheel 7. Inside both of the driving wheels 7 and the driven wheels 9, there are rotating rods 10 coaxially and fixedly connected. A plurality of the rotating rods 10 are all rotatably connected to the connecting rods 6.
[0019] Further, please refer to Figure 6 , coaxial fixed connections are provided on the exteriors of multiple rotating rods 10 with gears 11. Rack bars 12 are meshed and connected to the exteriors of multiple gears 11. Multiple rack bars 12 penetrate and are slidably connected to the right support 1 and the left support 2. One end of each of the multiple rack bars 12 away from the right support 1 and the left support 2 is fixedly connected to a jacket 13. By controlling the forward and reverse rotation and speed of the drive motor 38, the opening and closing degree of the jacket 13 can be precisely controlled to meet the requirements of different limb thicknesses.
[0020] Further, please refer to Figure 4 , the medicine adding mechanism 4 includes a medicine storage box 14, which is made of medical-grade transparent plastic material for convenient observation of the remaining amount of medicine. The medicine storage box 14 is fixedly connected to one of the jackets 13. A connecting head 15 is fixedly connected to the top of the medicine storage box 14. A connecting cap 16 is threadedly connected inside the connecting head 15. This connection method facilitates the opening of the connecting cap 16 to add medicine, while ensuring the sealing of the medicine storage box 14 to prevent medicine leakage and contamination. A regulating valve 17 is installed at the bottom of the medicine storage box 14. The regulating valve 17 can precisely control the outflow of medicine. A long tube 18 is fixedly connected to the bottom of the regulating valve 17. The long tube 18 is located inside the jacket 13 to guide the medicine from the medicine storage box 14 to near the wound surface.
[0021] In addition, it should be noted that flexible hoses 19 are uniformly fixedly connected to the bottom of the long tube 18. The flexible hoses 19 are made of soft and elastic medical-grade silicone material, which can adapt to the shape change of the jacket 13 to ensure the stability of medicine delivery. Pressure sensors 20 are installed on the exteriors of multiple flexible hoses 19. The pressure sensors 20 monitor the pressure of the medicine in the flexible hoses 19 in real time. When the pressure is abnormal, it can be timely fed back to the control system to adjust the opening degree of the regulating valve 17 to ensure stable medicine delivery. One end of each of the flexible hoses 19 away from the long tube 18 is fixedly connected to a micro nozzle 21. Multiple micro nozzles 21 are used to spray the medicine onto the wound surface. The micro nozzles 21 adopt a special atomization design, which can evenly spray the medicine onto the wound surface to improve the absorption efficiency of the medicine and promote wound repair.
[0022] Embodiment 2: As Figure 5 and Figure 9 shown, this is a further description of Embodiment 1. In this embodiment, the quick-release component 5 includes fixed blocks 22 symmetrically and fixedly installed on the left support 2. Through grooves 23 are opened inside both fixed blocks 22. Clamping blocks 24 are clamped inside both through grooves 23. This clamping method provides convenience for the connection of the right support 1 and the left support 2. Both clamping blocks 24 are fixedly connected to the right support 1. Slots 25 are symmetrically opened on the exteriors of both clamping blocks 24 for cooperation with the locking structure inside the fixed blocks 22.
[0023] Specifically, the two fixed blocks 22 are symmetrically provided with mounting grooves 26 communicating with the through grooves 23, and the multiple mounting grooves 26 are slidably connected with sliders 27, and the ends of the two sliders 27 that are away from each other are fixedly connected with adjustment rods 28, and the adjustment rods 28 are used to control the position of the sliders 27, and the ends of the two adjustment rods 28 that are away from each other are fixedly connected with shifting caps 30, which are convenient for manual operation by operators, and the sides of the two shifting caps 30 that are close to each other are fixedly connected with return springs 29, and the return springs 29 keep the sliders 27 in the locked position under normal conditions, that is, a part of the sliders 27 is inserted into the slots 25, so as to achieve the locking of the right bracket 1 and the left bracket 2. The ends of the two return springs 29 that are close to each other are fixedly connected with the fixed blocks 22, and when disassembly is required, the operator shifts the shifting caps 30 outwards, driving the adjustment rods 28 and the sliders 27 to overcome the elastic force of the return springs 29 and move outwards, so that the sliders 27 are separated from the slots 25, so that the right bracket 1 and the left bracket 2 can be easily separated.
[0024] Furthermore, the right bracket 1 and the left bracket 2 are fixedly connected with connecting blocks 34, one of the connecting blocks 34 is equipped with an electromagnetic suction 35, and the other connecting block 34 is equipped with a magnetic suction block 36. After the right bracket 1 and the left bracket 2 are initially connected through the clamping block 24 and the fixing block 22, the electromagnetic suction 35 is energized to generate magnetic force to attract the magnetic suction block 36, thereby further enhancing the stability of the connection and preventing the right bracket 1 and the left bracket 2 from accidentally separating during use.
[0025] In summary, when using this device, first, the through slot 23 in the symmetrical fixing block 22 on the left bracket 2 is engaged with the block 24 on the right bracket 1 to achieve a preliminary connection. When disassembling, the operator moves the cap 30 to drive the adjustment rod 28 and the slider 27 to overcome the elastic force of the reset spring 29 and move outward, so that the slider 27 is disengaged from the slot 25 to achieve separation. In addition, the electromagnetic suction 35 and the magnetic suction block 36 are respectively installed on the connecting block 34 of the right bracket 1 and the left bracket 2. After the right bracket 1 and the left bracket 2 are initially connected, the electromagnetic suction 35 is energized to generate magnetic force to attract the magnetic suction block 36, thereby enhancing the connection stability and preventing accidental separation; When the jacket 13 needs to be adjusted, start the drive motor 38, and its output shaft drives the driving wheel 7 connected to it through a coupling to rotate. The driving wheel 7 transmits power to the driven wheel 9 with the help of the belt 8, so that the two rotate synchronously. The rotating rod 10 coaxially fixed inside the driving wheel 7 and the driven wheel 9 rotates in the connecting rod 6, thereby driving the gear 11 coaxially fixed outside the rotating rod 10 to rotate. The gear 11 meshes with the rack 12, converting the rotational motion of the gear 11 into the linear motion of the rack 12, thereby driving the size of the jacket 13 to adjust. By controlling the forward and reverse rotation and speed of the drive motor 38, the opening and closing degree of the jacket 13 can be accurately controlled to adapt to different limbs; When medicine needs to be added, unscrew the connecting cap 16, add the medicine into the interior of the medicine storage box 14 through the connecting head 15, and then by starting the regulating valve 17, the medicine is evenly sprayed through the long tube 18 and the flexible tube 19 via the micro nozzle 21. The pressure sensor 20 can monitor the medicine pressure in real time and feed back to the control system when the pressure is abnormal, and adjust the opening degree of the regulating valve 17 to ensure stable medicine delivery.
