Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a limb supporting device and a bed used after skin grafting surgery. Background Art

[0002] Limb skin grafting is a widely used repair technique in plastic surgery, primarily used to repair skin defects in the limbs caused by various causes, such as burns, scalds, trauma, scar excision, and chronic ulcers. The core of limb skin grafting is to harvest skin tissue of appropriate size from other healthy areas of the patient's body (the donor site) and then transplant it to the defect site of the limb. The goal is to achieve skin coverage and functional restoration in the defect area, while also promoting the successful survival of the transplanted skin.

[0003] When performing skin grafting on the extremities, the selection of the donor site is crucial. Two key principles are generally followed: first, the color and texture must match the grafted area as closely as possible to minimize discomfort or cosmetic effects caused by color and texture differences after surgery; second, the donor site should be as concealed as possible to minimize the impact on the patient's appearance and improve their quality of life and psychological acceptance after surgery.

[0004] After skin grafting surgery, ensuring that the grafted area is free from pressure is key to ensuring graft survival and promoting wound healing. In addition, to maintain wound cleanliness and dryness, regular application of medication and dressing changes have become an indispensable part of postoperative care. In clinical practice, doctors will now instruct patients to adopt appropriate postures or place special support pads on the affected limbs to disperse pressure. However, the problem is that although support pads can disperse pressure to a certain extent, the affected limb will inevitably be subjected to a certain degree of pressure, especially when maintaining the same posture for a long time. In addition, when applying medication or changing dressings, the affected limb needs to be lifted for ease of operation, which undoubtedly increases the risk of accidental contact with the wound.

[0005] Therefore, how to design a limb support device for post-skin grafting surgery that can prevent the affected limb from being compressed and can be conveniently cared for without lifting the affected limb is a technical problem that has not yet been solved in the prior art. Utility Model Content

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that although the support pad can relieve pressure, the affected limb will still be under pressure when in the same posture for a long time, and the affected limb needs to be lifted when applying medicine or changing dressings, which increases the risk of accidental contact with the wound.

[0046] This embodiment provides a limb support device for post-skin grafting surgery, such as Figure 1 、 3 -5, comprising: a support rod 1, a fixed rod 2 and a lifting member 3; wherein, the support rod 1 is suitable for being detachably fixed on the bed guard; there is at least one fixed rod 2, which can be fixed on the support rod 1 and adjusted back and forth along the axial direction of the support rod 1 through a fixing structure; there is at least one lifting member 3, comprising an arc-shaped lifting member 4 and a connecting rod 5; the arc-shaped lifting member 4 is installed on the connecting rod 5 with an adjustable angle, and the connecting rod 5 is installed on the fixed rod 2 with an adjustable height.

[0047] When used on patients undergoing skin grafting surgery, the support rod 1 is first fixed to the bed rail, and then the fixing rod 2 is adjusted to the appropriate position according to the patient's needs. The height of the connecting rod 5 and the inclination angle of the arc-shaped lifting member 4 are adjusted according to the patient's physical comfort. After the adjustments are completed, the affected limb is placed on the arc-shaped lifting member 4 so that the skin graft area is located between the two arc-shaped lifting members 4. This embodiment of the limb support device for post-skin grafting surgery can prevent compression of the skin graft area and ensure the patient's comfort during the recovery process. During the nursing process, nursing work can be completed conveniently without lifting the affected limb, reducing the risk of accidentally touching the wound and improving the efficiency of nursing work.

[0048] The curved support member 4 comprises a curved support plate 41 and a connector 43.

A first fixing bolt 61 is threadedly engaged with the first threaded hole 6 and is used to press against the spherical portion 45 to secure the spherical portion 45 in position. A first operating lever 62 is fixedly mounted on the operating end of the first fixing bolt 61. To adjust the angle of the arc-shaped lifting member 4, the first fixing bolt 61 is first rotated outward to remove the pressure from the spherical portion 45. The spherical portion 45 is then rotated to adjust the arc-shaped lifting member 4 to a comfortable angle for the patient. The first fixing bolt 61 is then rotated inward to re-press against the spherical portion 45, securing the spherical portion 45 in position.

[0051] One end of the fixing rod 2 defines a mounting hole 21, within which the L-shaped rod 51 is mounted for vertical movement. A side wall of the fixing rod 2 defines a second threaded hole 63 communicating with the mounting hole 21. A second fixing bolt 64 is threadedly engaged with the second threaded hole 63, configured to press against the L-shaped rod 51 to secure the rod 51 in position. A second operating lever 65 is fixed to the operating end of the second fixing bolt 64. To adjust the height of the L-shaped rod 51, the second fixing bolt 64 is first rotated outward to release the pressure from the second fixing bolt 64 against the L-shaped rod 51. The L-shaped rod 51 is then rotated to a comfortable height for the patient. The second fixing bolt 64 is then rotated inward to re-press the L-shaped rod 51, securing the rod 51 in position.

[0052] The fixing structure includes: a movable fixing part 7 and a third fixing bolt 67; wherein the movable fixing part 7 is movably mounted on the support rod 1, and a third threaded hole 66 is opened on the top; the third fixing bolt 67 is screwed into the third threaded hole 66, and a third operating rotating rod 68 is fixedly provided on the operating end.

[0053] A fixing through-hole 71 is formed on a side wall of the movable fixing member 7, and the fixing rod 2 is movably inserted into the fixing through-hole 71. The third fixing bolt 67 is threadedly engaged with the third threaded hole 66, and is used to press against the fixing rod 2 to limit the position of the fixing rod 2. When adjusting the position of the fixing rod 2, the third fixing bolt 67 is first rotated outward so that it no longer presses against the fixing rod 2. The movable fixing member 7 is then slid on the support rod 1 to adjust the fixing rod 2 to the appropriate position. The third fixing bolt 67 is then rotated inward so that it presses against the fixing rod 2 again, thereby limiting the position of the fixing rod 2.

[0054] The support rod 1 is provided with at least one long opening 12 for installing the fixing rod 2, and mounting rods 13 are fixedly arranged on the same side of both ends of the long opening 12; the axis of the mounting rod 13 forms an angle of 90° with the axis of the support rod 1, and a fixing part 14 is fixed on the free end.

[0055] like Figure 2 As shown, the fixing member 14 includes two oppositely arranged arc-shaped clamping plates 15, one end of which is rotatably connected and the other end is designed to be opened and closed, and the other end can be closed and fixed by a bolt assembly 16. When fixing the support rod 1, the two arc-shaped clamping plates 15 are opened and the bed guard is placed between the two opened arc-shaped clamping plates 15; after confirming the fixed position, the two arc-shaped clamping plates 15 are clamped and fixed by the bolt assembly 16, and the clamping force of the arc-shaped clamping plates 15 is used to fix the support rod 1 to the bed guard.

[0056] The limb support device used after skin grafting surgery in this embodiment is used as follows:

[0057] When used on patients after skin grafting surgery, the two curved splints 15 are first opened, and the bed guard is placed between the two opened curved splints 15; after confirming the fixed position, the two curved splints 15 are clamped and fixed by the bolt assembly 16, and the support rod 1 is fixed to the bed guard by the clamping force of the curved splints 15;

[0058] When adjusting the position of the fixing rod 2, first turn the third fixing bolt 67 outward so that the third fixing bolt 67 no longer presses against the fixing rod 2; then adjust the fixing rod 2 to the appropriate position by sliding the moving fixing member 7 on the support rod 1; then turn the third fixing bolt 67 inward so that the third fixing bolt 67 presses against the fixing rod 2 again and fixes the fixing rod 2 in a limited position;

[0059] When adjusting the height of the L-shaped rod 51, first rotate the second fixing bolt 64 outward so that the second fixing bolt 64 no longer presses against the L-shaped rod 51; then rotate the L-shaped rod 51 to a height that is comfortable for the patient; then rotate the second fixing bolt 64 inward so that the second fixing bolt 64 presses against the L-shaped rod 51 again, thereby limiting and fixing the L-shaped rod 51;

[0060] When adjusting the angle of the arc-shaped supporting member 4, first rotate the first fixing bolt 61 outward so that the first fixing bolt 61 no longer presses against the spherical portion 45; then rotate the spherical portion 45 to adjust the arc-shaped supporting member 4 to an angle that the patient feels comfortable with; then rotate the first fixing bolt 61 inward so that the first fixing bolt 61 presses against the spherical portion 45 again and limits the spherical portion 45 to fix it; after the adjustment is completed, place the affected limb on the arc-shaped supporting member 4 so that the skin grafting area is located between the two arc-shaped supporting members 4.
