Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a leg care support for orthopedic surgery. Background Technology

[0002] Orthopedic surgery is a medical discipline that specializes in the study of diseases and injuries of bones, joints, muscles, ligaments and related soft tissues. After a patient undergoes surgery on their leg, it is usually necessary to support and immobilize the patient's leg to promote blood circulation, wound healing and prevent secondary injury.

[0003] A leg support bracket is a device that provides external support and fixation to the leg through a mechanical structure after surgery. Existing leg support brackets mainly consist of components such as a support frame, a support plate, and straps. When in use, the support frame and support plate are used to lift the leg, and then the support plate is fixed to the leg with straps to achieve stable maintenance of the leg position.

[0004] However, patients who have undergone knee ligament surgery need to get out of bed frequently for rehabilitation training during the rehabilitation period. Existing braces rely on external support structures for fixation, which only support and fix the patient's legs while in bed. When patients get out of bed, the braces need to be completely removed. During the transition from bed to sitting or even standing on one leg, the legs lose the support and fixation of the braces, which can easily cause secondary damage to the ligaments and is not conducive to the rehabilitation after ligament surgery. Summary of the Invention

[0005] The purpose of this invention is to address the problem that traditional leg supports only provide leg support when the patient is in a bedridden position, and that the patient's legs are prone to secondary injury when they get out of bed and are transferred to the rehabilitation training room, as the support of the leg supports is lost. Therefore, this invention proposes a leg care support for orthopedic surgery.

[0006] To achieve the above objectives, the present invention employs the following technology: a leg care bracket for orthopedic surgery, comprising a support rod and a stabilizing mechanism, wherein the stabilizing mechanism includes a connecting frame, one end of which is slidably connected to a slider, the slider being provided with a locking unit, and a support component being installed on one side of the slider and the end of the connecting frame away from the slider. The support assembly includes a support plate, which is rotatably connected to a connecting frame and a slider via a rotating shaft. An end cap is fixed to the end of the rotating shaft, and the end cap can be fixed to the connecting frame via a threaded knob. When the patient is lying down, the two support plates support and lift the thighs and calves respectively; when the patient is standing, the stabilizing mechanism is worn on the legs, with the two support plates supporting the back of the thighs and the front of the calves respectively.

[0007] As a further description of the above-mentioned leg care bracket for orthopedic surgery: a fitting seat is fixed to the top of the support rod, and the connecting frame is horizontally fitted between the support rod and the fitting seat.

[0008] As a further description of the above-mentioned leg care bracket for orthopedic surgery: the bracket is provided with Velcro, the Velcro including a hook-and-loop strap fixed to one side of the bracket, and a looped strap is attached to the outer wall of the bracket.

[0009] As a further description of the above-mentioned leg care bracket for orthopedic surgery: the locking unit includes a threaded rod rotatably connected to one side of the slider, the external thread of the threaded rod being slidably connected to a fixing block of the connecting frame.

[0010] As a further description of the above-mentioned leg care support for orthopedic surgery, it also includes an airbag protection mechanism, which includes an airbag strap attached to and fixed to the inner wall of the support plate.

[0011] As a further description of the above-mentioned leg care bracket for orthopedic surgery: the airbag bands on the inner walls of the two brackets are connected by a hose.

[0012] As a further description of the above-mentioned leg care bracket for orthopedic surgery: the airbag belt is composed of several strip-shaped airbags, and a fitting component is provided on the inner wall of the bracket corresponding to the position of each strip-shaped airbag.

[0013] As a further description of the above-mentioned leg care bracket for orthopedic surgery: the fitting assembly includes a fitting plate fixed to the inner wall of the support plate by two plastic sheets, the connection between the plastic sheets and the support plate and the fitting plate is flexible, and the two plastic sheets are inclined in the same direction.

[0014] As a further description of the above-mentioned leg care bracket for orthopedic surgery: a plurality of sponge blocks are fixed on the surface of the adhesive plate in a straight line at equal intervals.

[0015] As a further description of the above-mentioned leg care bracket for orthopedic surgery: the support rod is mounted on one side of the hospital bed via a mounting seat, the support rod is slidably connected to the mounting seat and can be fixed by a threaded knob, and the mounting seat is fixed to the hospital bed by a threaded knob.

[0016] In summary, due to the adoption of the above-mentioned technology in the orthopedic leg care bracket, the beneficial effects of this invention are: 1. This application uses two adjustable support plates to support and lift the thigh and lower leg respectively. The height of the support plate for lifting the lower leg is adjustable. Therefore, the two support plates can support and lift the leg according to the position and angle of the thigh and lower leg respectively, restricting knee joint movement and ensuring the healing effect after knee ligament surgery. Moreover, the stabilizing mechanism is designed to be wearable, so that it can be worn on the leg when the patient gets out of bed, continuously maintaining the flexion of the leg, avoiding damage to unhealed ligaments, and facilitating the patient to get out of bed and carry out rehabilitation training.

[0017] 2. Position the two support plates at the bottom and front of the leg respectively to form a clamping and limiting state for the leg. This state can lock the joint at a preset angle through the support and pressing structure, strictly control the joint flexion angle, avoid the leg from being unconsciously straightened or excessively bent, effectively prevent stress on the ligament repair site, and reduce the risk of secondary injury. The support plate for the lower leg can be adjusted in position via a slider. Adjusting the support position of the lower leg allows the operated leg to hang naturally while the patient is wearing the stabilizing device, reducing the strain on the thigh, making it more effortless and comfortable, facilitating patient movement, and aiding in postoperative recovery of the leg.

[0018] 3. When the patient moves, the two airbags expand alternately under the natural pressure of the legs, lifting the adhesive plate and causing the sponge block to press on the legs, promoting blood circulation in the legs. At the same time as the adhesive plate is lifted, it moves axially, changing the contact position between the sponge block and the legs, further improving the pressure effect, and preventing the sponge block from continuously pressing on local areas of the legs, which can cause discomfort.

[0020] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a leg care bracket for orthopedic surgery according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-14 As shown, the present invention provides a leg care support for orthopedic surgery: including a support rod 10, a mounting base 11, and a stabilizing mechanism. The support rod 10 slides with the mounting base 11 and is mounted on one side of the hospital bed through the mounting base 11. The support rod 10 and the mounting base 11 can be fixed together by a threaded knob. The height of the stabilizing mechanism can be adjusted by adjusting the height of the support rod 10 extending from the mounting base 11, thereby providing stable support for the patient's leg according to the actual situation. The mounting base 11 is clamped and mounted on one side of the hospital bed and can be fixed to the hospital bed through a threaded knob. The stabilizing mechanism includes a connecting frame 21, with a slider 23 slidably connected to one end of the connecting frame 21. Supporting components 24 are installed on one side of the slider 23 and the end of the connecting frame 21 away from the slider 23. A locking unit 26 is provided on the slider 23 to fix the slider 23 to the connecting frame 21. The support assembly 24 includes a semi-circular tube-shaped support plate 241. Both ends of the support plate 241 are bent towards the back to prevent the edges from being squeezed against the legs. A rotating shaft 242 is fixed to one side of the support plate 241. The rotating shafts 242 on one side of the two support plates 241 respectively pass through the connecting frame 21 and the slider 23 and are rotatably connected to the connecting frame 21 and the slider 23. An end cap 243 is fixed to the end of the rotating shaft 242. The end cap 243 can be fixed to the connecting frame 21 by a threaded knob. Both trays 241 can rotate around the pivot 242 in a vertical plane to adjust the opening orientation. After adjusting the orientation, the end cap 243 is locked to the connecting frame 21 using a threaded knob to fix the trays 241. When the patient is in bed, the two trays 241 can be adjusted to the following position: Figure 1 As shown, the two support plates 241 support and lift the patient's thigh and calf respectively, promoting venous return, reducing postoperative edema, and providing a good blood circulation environment for ligament healing. In addition, the semi-circular support plate 241 restricts lateral movement of the leg, preventing secondary damage to the ligament surgery site caused by leg movement when the patient is lying down.

[0022] Reference Figure 4 and Figure 5 The support component 24 located on one side of the slider 23 can be height adjusted by the slider 23. The locking unit 26 includes a threaded rod 261 rotatably connected to one side of the slider 23. A strip hole is opened on the end face of the connecting frame 21 near the slider 23. The outer end of the threaded rod 261 passes through the strip hole. The external thread of the threaded rod 261 is connected to a fixing block 262 that is slidably connected to the connecting frame 21. Twisting the threaded rod 261 causes the fixing block 262 to move away from the slider 23, so that the fixing block 262 contacts and presses against the inner wall of the connecting frame 21. The position of the slider 23 is locked by the friction between the fixing block 262 and the connecting frame 21, and the slider 23 is fixed after the height is adjusted.

[0023] After knee ligament surgery, joint movement needs to be restricted to avoid excessive stretching or loosening of the ligament repair area. The angles of the two support plates 241 can be adjusted independently, and the height of the support plate 241 used to support the lower leg is adjustable. Figure 10 and Figure 11 As shown, the two support plates 241 can support the legs according to the position and angle of the thigh and calf, respectively, restricting knee joint movement and ensuring the healing effect of ligaments.

[0024] Reference Figure 12 and Figure 13During the patient's rehabilitation transition period, it is necessary to precisely maintain the joint flexion angle to avoid traction or relaxation of the ligament repair site due to slight movement. At this time, the position and angle of the two support plates 241 are adjusted according to the actual situation so that the two support plates 241 are located at the bottom and front of the leg respectively. The two support plates 241 form a clamping and limiting state for the leg. Compared with the two support plates 241 supporting the thigh and calf respectively, this state can lock the joint at the preset angle through the support and pressing structure, strictly control the joint flexion angle, avoid the leg from unconsciously straightening or excessively bending, effectively prevent the ligament repair site from being stressed, and reduce the risk of secondary injury.

[0025] Considering that patients need to get out of bed frequently for rehabilitation training during rehabilitation care, in order to make full use of the support and avoid damage to unhealed ligaments caused by changes in leg flexion during patient movement, the stabilizing mechanism is designed to be wearable. The connecting frame 21, slider 23 and support component 24 can all be made of aluminum alloy or titanium alloy to ensure strength while reducing the weight of the wearer. Reference Figure 2 The top of the support rod 10 is fixed with a fitting seat 22, and the connecting frame 21 is horizontally fitted between the support rod 10 and the fitting seat 22. In this state, the connecting frame 21 can only be dislodged vertically upward from between the support rod 10 and the fitting seat 22 to ensure the stability of the support leg of the support component 24.

[0026] Reference Figure 3 , Figure 4 and Figure 7 The tray 241 is provided with Velcro 25, which includes a hook-and-loop strap 251 fixed to one side of the tray 241. A looped strap 252 is attached to the outer wall of the tray 241. The hook-and-loop strap 251 is wrapped around the leg and attached to the looped strap 252, so that the tray 241 is tied to the leg to achieve wearing.

[0027] Before the patient gets out of bed, adjust the angles of the two support plates 241 so that they fit against the back of the patient's thigh and the front of the lower leg, respectively. Then, use Velcro 25 to secure the support plates 241 to the legs. After the patient stands upright, the legs and the stabilizing mechanism are in the following position. Figure 14 As shown, at this time, the two support plates 241 are respectively supported at the bottom of the thigh and the front of the calf, restricting the bending posture of the thigh and calf, thereby avoiding damage to the unhealed ligaments.

[0028] It needs to be emphasized that, Figure 14 This refers to the support the stabilizing device provides to the patient's legs when they are standing. Figure 12 The stability of the device for supporting the patient's legs while lying in bed. Figure 14 and Figure 12 The difference is that, Figure 14In this state, the slider 23 adjusts the support plate 241 of the lower leg to be located on the connecting frame 21, so that the patient's surgical leg can hang naturally, making it more effortless and comfortable to stand, which helps the leg to recover after surgery.

[0029] Reference Figure 2 and Figure 6 Based on the above design, in order to improve the comfort of the support component 24, an airbag protection mechanism is provided inside the support plate 241. The airbag protection mechanism includes an airbag band 31 attached and fixed to the inner wall of the support plate 241. The airbag band 31 is composed of several strip-shaped airbags connected to each other. The airbag band 31 can cushion the thigh and calf muscles to avoid pressure pain caused by long-term support of the support plate 241.

[0030] The airbag straps 31 on the inner walls of the two support plates 241 are connected by a hose 32. The hose 32 has redundant length. When the angle of the two support plates 241 is adjusted, the hose 32 always connects the two airbag straps 31. To prevent the hose 32 from getting tangled around the legs or swinging too long, the excess hose 32 can be fixed with a cable tie after the angle of the support plate 241 is adjusted.

[0031] When the patient wears the stabilization device, two support plates 241 are placed on the back of the thigh and the front of the calf, respectively. Two airbag straps 31 are located between the leg and the support plates 241. When the patient moves, the leg will continuously compress the two airbag straps 31. When there is a difference in the compressive force on the two airbag straps 31, the air inside the airbag strap 31 with greater pressure will be squeezed into the other airbag strap 31, causing the airbag strap 31 to inflate and increase the pressure between it and the leg. This design allows the two airbag straps 31 to inflate alternately when the patient wears the stabilization device, thereby compressing the leg, promoting blood circulation, and reducing the risk of deep vein thrombosis.

[0032] Reference Figure 7 , Figure 8 and Figure 9 On the inner wall of the support plate 241, a fitting component 33 is provided at each position of the strip airbag. The fitting component 33 includes a fitting plate 331 fixed to the inner wall of the support plate 241 by two plastic sheets 332. The two ends and the two side edges of the fitting plate 331 are bent towards the inner wall of the support plate 241 to limit the position of the strip airbag and avoid the sharp corners squeezing the legs and causing discomfort. The connection between the plastic sheet 332 and the support plate 241 and the fitting plate 331 is flexible. The two plastic sheets 332 are inclined in the same direction. Several sponge blocks 333 are fixed on the surface of the fitting plate 331 in a straight line at equal intervals. When each strip-shaped airbag in the airbag belt 31 inflates, it will push up the bonding plate 331 above it, causing the bonding plate 331 to drive the sponge block 333 to press on the leg. At the same time, the bonding plate 331 will drive the plastic sheet 332 to deflect in the vertical direction. Therefore, the bonding plate 331 will move axially while being pushed up, changing the contact position between the sponge block 333 and the leg, and further improving the pressing effect. Furthermore, the sponge block 333 will change its contact position with the leg according to the degree of inflation of the airbag belt 31, avoiding prolonged massage pressure on the same part of the patient's leg, preventing muscle soreness, eliminating pressure sores, and promoting blood circulation in the leg.

[0033] Working principle: The mounting base 11 is clamped to one side of the hospital bed and fixed to the hospital bed by the threaded knob; When the patient is in bed, the angle of the support plate 241 is adjusted according to the required support posture of the patient's legs. The support plate 241 drives the end cover 243 to rotate through the pivot 242. After the angle is adjusted, the end cover 243 is fixed to the connecting frame 21 through the threaded knob. Then, the support rod 10 is pulled up, which drives the connecting frame 21 and the support assembly 24 to move up, so that the support plate 241 contacts the patient's legs and supports and lifts the legs. Finally, the support rod 10 and the mounting base 11 are fixed through the threaded knob. When it is necessary to strictly control the flexion angle of the patient's leg joint, flip one of the support plates 241, release the lock of the slider 23 through the locking unit 26, leave space for the leg to pass through, and let the patient's leg pass through the inside of the two support plates 241 so that the leg and the support plate 241 connected to the connecting frame 21 through the pivot 242 fit against the leg. Then adjust the position of the slider 23 so that the other support plate 241 fits against the leg. Then bind and fix the leg to the support plate 241 with Velcro 25, and restrict the bending movement of the leg through the two support plates 241. When the patient needs to get out of bed, the position of the support plate 241 connected to it is adjusted by the slider 23, and the angle of the two support plates 241 is adjusted so that the patient's legs wearing the stabilizing mechanism are comfortable while standing. Then the height of the support rod 10 is lowered so that the connecting frame 21 is disengaged from the support rod 10 and the fitting seat 22. At this time, the two support components 24 and the connecting frame 21 support and restrict the patient's legs, so that the patient can get out of bed and move around. When a patient wearing the stabilization device gets out of bed, their legs continuously compress the two airbag bands 31. When there is a difference in the compressive force on the two airbag bands 31, the air inside the airbag band 31 with greater pressure is squeezed into the other airbag band 31, causing that airbag band 31 to inflate. Therefore, the two airbag bands 31 inflate alternately. When the strip-shaped airbags of the airbag bands 31 inflate, they push up the adhesive plate 331 above them. This causes the adhesive plate 331 to move the sponge block 333 to press on the legs. At the same time, the adhesive plate 331 causes the plastic sheet 332 to deflect vertically. Therefore, the adhesive plate 331 moves axially as it is pushed up, changing the contact position between the sponge block 333 and the legs, further improving the compression effect and preventing continuous pressure on certain parts of the legs, which can cause discomfort.
