Description

Technical Field

[0001] The present invention relates to the field of auxiliary devices for lower limb postoperative recovery, and particularly to a leg support device with a skin flap avoidance function. Background Art

[0002] A skin flap refers to a piece of skin with a blood supply and its attached subcutaneous fat tissue, which not only includes the epidermis, but also the dermis and part of the subcutaneous tissue, and may even include structures such as muscles and tendons. In a skin flap operation, a surgeon will transplant the patient's own skin, subcutaneous tissue or muscle and transplant it to the site that needs to be repaired. This kind of operation can help restore the function and appearance of the injured site. Skin flap operations can be used to repair skin and tissue defects caused by severe trauma, burns or other external injuries. After a surgical operation, sometimes a skin flap operation may be required to repair the tissue defect at the surgical site. Preventing infection and promoting blood circulation after a skin flap operation are the keys to the survival of the skin flap. Therefore, the limb needs to be isolated from the bedsheet and the limb needs to be placed in a predetermined posture to prevent foreign body contact infection and promote blood supply.

[0003] In the prior art, after a lower limb skin flap operation, a lower limb elevation pad disclosed in CN221888613U is used to support the patient's lower limb.

Detailed implementation manners

[0040] To make the objectives, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0043] In the prior art, after a lower limb skin flap operation, a lower limb elevation pad disclosed in CN221888613U is used to support the lower limbs of a patient. The problem of the prior art is that the support pad does not have the function of avoiding the skin flap part of the patient. When the part where the patient's transplanted skin flap is located is on the lower side, the skin flap is easily squeezed due to posture adjustment, and even the skin flap necrosis may occur.

[0044] Based on the above problems in the prior art, the present invention provides a leg support device with a skin flap avoidance function, as Figure 1 and Figure 2As shown in the figure, the leg support device with a flap avoidance function includes: a groove body 100, in which a plurality of support blocks 200 are arranged side by side and slidably along the length direction of the groove body 100. Locking members 210 extending out of the groove body 100 are respectively arranged at both ends of the support blocks 200, and the locking members 210 are detachably and snap-fitted with a sliding groove 110 arranged along the height direction of the groove body 100 on the groove body 100; a bottom plate 300, one end of the bottom plate 300 is rotatably connected to the bottom of the groove body 100, and an adjusting assembly 400 is arranged at the other end of the bottom plate 300, and the adjusting assembly 400 is used to fix the relative angle between the bottom plate 300 and the groove body 100.

[0045] In the present invention, a plurality of support blocks 200 arranged side by side are provided inside the groove body 100. The locking members 210 on both sides of the support blocks 200 are engaged with the sliding grooves 110 on the groove body 100, so as to realize the adjustment of different heights of different support blocks 200, thereby realizing the avoidance of the flap part while supporting the lower limbs of the patient and the adjustment for patients of different body sizes. By fixing the relative angle between the bottom plate 300 and the groove body 100 through the adjusting assembly 400, the effect of lifting the lower limbs of the patient at different angles can be satisfied. The adjustment process does not require the patient to move, and the requirements such as lifting the lower limbs of the patient and avoiding the flap part can be met, creating better conditions for the survival of the flap.

[0046] In the above embodiment, as Figure 1 and Figure 2 shown, the inside of the groove body 100 is hollow, and the groove body 100 includes two side plates arranged in parallel. The support blocks 200 are located between the two side plates of the groove body 100 and are slidably connected to the groove body 100, so that the support blocks 200 can slide up and down inside the groove body 100. A plurality of support blocks 200 are arranged side by side to form a plurality of adjusting structures along the length direction of the groove body 100. At the same time, sliding grooves 110 are arranged on the side plates of the groove body 100. The locking members 210 at both ends of the support blocks 200 penetrate to the outside of the side plates and are combined with the corresponding sliding grooves 110 to form a connection structure detachably and snap-fitted with the sliding grooves 110. By holding and moving the locking members 210, the support blocks 200 can be moved along the sliding grooves 110 arranged along the height direction of the groove body 100, so as to adjust the height of different support blocks 200. For example Figure 2 as shown in the adjustment style, if the height of some support blocks 200 is lower and the height of other support blocks 200 is higher, the effect of avoiding the flap part while supporting the lower limbs of the patient can be realized. At the same time, by adjusting the support blocks 200 at different positions, patients with different lower limb lengths can be adapted.

[0047] In actual application, since the support for the lower limbs should have a certain angle to promote blood circulation in patients, a bottom plate 300 is further provided below the groove body 100 in this embodiment. One end of the bottom plate 300 is rotatably connected to the bottom of the groove body 100, and an adjusting assembly 400 is provided at the other end. The relative angle between the bottom plate 300 and the bottom of the groove body 100 can be fixed through the adjusting assembly 400, thereby realizing the adjustment of the placement angle of the groove body 100. In actual application, the adjusting assembly 400 can be adjusted according to the lower limb placement requirements of different patients to meet the comfort of patients during use and the effect of promoting blood circulation.

[0048] In this embodiment, the adjustment of the support block 200 and the angle adjustment between the bottom plate 300 and the groove body 100 can be operated when the lower limbs of the patient are placed. Moreover, the operation process is simple and there is no complex operation such as disassembly. Therefore, it can meet the fine adjustment during the use of the patient, and then cooperate with the recovery progress of the flap. Compared with the leg support devices in the prior art, the operation convenience is greatly improved, and the probability of the flap being squeezed due to moving the patient or adjusting the patient's posture is reduced.

[0049] In another implementable manner of the present invention, as Figure 4 shown, to achieve the detachable cooperation between the locking member 210 and the sliding groove 110, a mounting seat 220 is provided inside the support block 200. One end of the locking member 210 located inside the support block 200 is slidably connected to the mounting seat 220 and elastically connected to the mounting seat 220, so as to form an effect that during operation, medical staff can pull the locking members 210 on both sides to change the combined state of the locking member 210 and the support block 200 to adjust the height of the support block 200; correspondingly, to fix the position of the support block 200 after adjusting the height, as Figure 1 and Figure 2 shown, in this embodiment, a plurality of gear slots 111 are evenly arranged along the length direction of the sliding groove 110 on the sliding groove 110. The gear slots 111 are perpendicular to the sliding groove 110 and are arranged in a penetrating manner with the sliding groove 110, forming a partial cross-shaped hollow structure;

[0050] At the same time, a tenon 211 is provided on the locking member 210 corresponding to the position of the sliding groove 110. Please combine Figure 4 and Figure 5The cross-sectional shape of the tenon 211 is a cross shape, and is adapted to the shape of the intersection of the above-mentioned slide groove 110 and the gear groove 111. The side edge of the tenon 211 is inclined at a predetermined angle. In actual use, since the locking member 210 is elastically and slidably connected to the above-mentioned mounting seat 220, two structural states can be formed in which the locking member 210 is pulled out relative to the two side walls of the support block 200 and reset relative to the side walls of the support block 200. When the locking member 210 is reset relative to the side walls of the support block 200, The U-shaped latch 211 can be engaged with the intersection of the cross-shaped slide groove 110 and the gear slot 111 at the corresponding position, so as to fix the height position of the support block 200; when the medical staff operates the locking member 210 to pull out, the latch 211 and the intersection of the cross-shaped slide groove 110 and the gear slot 111 at the corresponding position are released, and the locking member 210 can move along the length direction of the slide groove 110, that is, the effect of directional adjustment of the position of the support block 200 is achieved. The actual adjustment effect can be referred to Figure 1 and Figure 2 By raising some support blocks 200 and lowering some support blocks 200, it is possible to support the patient's lower limbs while avoiding the skin flap, and to adapt the leg support device with the skin flap avoidance function to the length of the patient's lower limbs.

[0051] Furthermore, if Figure 4 As shown, in order to make the combined structure of the locking member 210 and the support block 200 more secure, the partial structure of the locking member 210 inside the support block 200 is set to a rigid rod shape. In this embodiment, a base 230 is fixedly set inside the support block 200, and a limiting hole 231 is set on the base 230 corresponding to one side of the mounting seat 220. One end of the locking member 210 is slidably sleeved in the limiting hole 231, and a relative slot and protrusion structure can be set to limit the sliding limit of the locking member 210. The locking member 210 is positioned in the position to prevent the locking member 210 from being disengaged from the limiting hole 231. At the same time, a compression spring 240 is sleeved on the outer side of the locking member 210. A limiting ring 212 is arranged on the outer side of the locking member 210. One end of the compression spring 240 is fixedly connected to the limiting ring 212, and the other end is fixedly connected to the mounting seat 220. Through the pre-pressure of the compression spring 240, the limiting ring 212 is abutted against the base 230 on the side away from the mounting seat 220. At this point, the two moving limit positions of the locking member 210 are limited.

[0052] like Figure 4 As shown, of the two extreme movement positions, one is the illustrated state, that is, the limiting ring 212 on the locking member 210 abuts against the base 230 under the action of the compression spring 240, which corresponds to the state in which the locking member 210 is engaged with the intersection of the slide groove 110 and the gear groove 111; the other is that the locking member 210 is pulled out, that is, Figure 4The locking member 210 shown in the figure moves to the left and right by a certain distance respectively. In this case, the locking member 210 is released from the intersecting part of the slide groove 110 and the gear groove 111. The medical staff can adjust the position of the support block 200 along the length direction of the slide groove 110. At the same time, the compression spring 240 is in a compressed state. When the medical staff adjusts the position and cancels the force, the locking member 210 is reset to Figure 4 state, so as to engage with the intersecting parts of the slide groove 110 and the gear groove 111 at the corresponding parts, and lock the adjusted position of the support block 200.

[0053] Through the structural coordination of the above-mentioned base 230, mounting seat 220 and locking member 210, the movable direction of the locking member 210 is limited. At the same time, since the contact part between the locking member 210 and the slot body 100 is the main load-bearing part when the support block 200 supports the patient's lower limbs, the arrangement of the base 230 and the mounting seat 220 can share the force of the locking member 210, thereby increasing the service life. On the other hand, in combination with the arrangement of the compression spring 240, the locking member 210 has the function of automatic reset and engagement, and in combination with the side of the tenon 211 inclined at a predetermined angle, it can assist in locking the position of the support block 200, thereby simplifying the operation of medical staff and improving the operating efficiency of medical staff.

[0054] In the above embodiment, if Figure 1 and Figure 2 As shown, in order to facilitate medical staff to grasp and apply force to the locking member 210, the ends of the locking member 210 that extend out of the groove body 100 on both sides can be set to a spherical shape during actual setting. At the same time, another advantage of such a setting is that it can prevent the patient from contacting the locking member 210 when adjusting the body position, causing discomfort.

[0055] In another embodiment of the present invention, Figure 2 and Figure 3 As shown, the above-mentioned adjustment component 400 is specifically composed of a telescopic rod 410 and a fixed seat 420, wherein one end of the telescopic rod 410 is rotatably connected to the bottom of the above-mentioned slot body 100, and the other end of the telescopic rod 410 is provided with a universal ball 415. Correspondingly, the fixed seat 420 is detachably arranged on the bottom plate 300, and an adjustment cavity adapted to the shape of the universal ball 415 is arranged inside the fixed seat 420, and a clearance hole is arranged above the fixed seat 420. The telescopic rod 410 penetrates into the adjustment cavity along the clearance hole, and the universal ball 415 is engaged and rotatably arranged in the adjustment cavity. When the length of the telescopic rod 410 is adjusted, the relative angle between the bottom of the slot body 100 and the bottom plate 300 can be adjusted, thereby forming a support effect of different support angles for the patient's lower limbs.

[0056] Specifically, when adjusting the length of the telescopic rod 410, the end of the telescopic rod 410 rotatably connected to the bottom of the base 230 rotates adaptively, and the universal ball 415 rotates adaptively within the fixed seat 420, thereby forming an adaptation to the current support angle.

[0057] Furthermore, the telescopic rod 410 is specifically composed of a first rod body 411 and a second rod body 412. One end of the first rod body 411 is sleeved and slidably arranged inside the second rod body 412 to form a sliding sleeve connection. To lock the relative positions of the first rod body 411 and the second rod body 412, in this embodiment, a lock catch 413 is provided at one end of the first rod body 411 corresponding to the inside of the second rod body 412. The lock catch 413 is elastically connected to the first rod body 411 and partially protrudes outside the first rod body 411. The protruding part outside the first rod body 411 is cylindrical with a hemispherical end. Correspondingly, a plurality of adjustment holes 414 are arranged along the length direction of the second rod body 412. The diameter size of the adjustment holes 414 is adapted to the diameter size of the protruding part of the lock catch 413, and the lock catch 413 forms a detachable snap connection with the plurality of adjustment holes 414. During actual use, by combining the lock catch 413 with the adjustment holes 414 at different positions, the telescopic rod 410 can be adjusted to different lengths, and further, the relative angle between the bottom plate 300 and the bottom of the groove body 100 can be fixed.

[0058] In another feasible embodiment, to enable the leg support device with a flap avoidance function of the present invention to have a more comfortable usage experience, as Figure 1 and Figure 2 shown, during actual setting, it is preferably set that both ends of the groove body 100 in the length direction are open. At the same time, a transition support member 500 is provided at one end of the groove body 100. The upper side of the transition support member 500 is arranged along a predetermined arc for forming a transition support for the popliteal fossa part of the patient, thereby increasing the contact area between the leg support device with a flap avoidance function and the lower limb of the patient, and at the same time making the support arc adapt to the lower limb of the human body to avoid the fatigue caused by the long-term suspension of the leg muscles.

[0059] In this embodiment, the transition support member 500 is fixedly connected to the groove body 100, and the upper side of the transition support member 500 is elastically arranged to prevent the occurrence of pressure sores. Based on this structural setting, one end of the bottom plate 300 should be rotatably arranged on the transition support member 500 to ensure that after the angle between the groove body 100 and the bottom plate 300 is adjusted, the arcs of the support block 200 and the transition support member 500 are adapted to the arc of the lower limb of the human body.

[0060] A functional component 600 is provided at the other end of the trough body 100. The functional component 600 includes a number of functional surfaces. When the patient places the lower limbs on the above-mentioned transition support member 500 and a number of support blocks 200, the sole part of the patient corresponds to the functional component 600, so as to perform rehabilitation operations such as massaging and assisting the movement of the patient's feet, or fixing the patient's feet.

[0061] In actual setting, the above-mentioned functional component 600 should be slidably arranged along the length direction of the trough body 100 for use by patients with different lower limb lengths. At the same time, the functional component 600 should be rotatably connected to the trough body 100 for switching different functional surfaces of the functional component 600. In a specific embodiment, adjustment grooves 120 can be provided in a hollow manner at the positions corresponding to the functional component 600 on both side walls of the trough body 100. The adjustment grooves 120 are arranged along the length direction of the trough body 100, and locking handles 601 are respectively provided at both ends of the functional component 600. The locking handles 601 clamp the trough body 100 and are threadedly connected to the functional component 600. In actual use, the locking handle 601 can be rotated in a predetermined direction so that the locking handle 601 abuts against the side wall, and the functional component 600 is clamped by the two side walls of the trough body 100. At this time, the position of the functional component 600 is locked and cannot rotate relative to the trough body 100; when the medical staff rotates the locking handle 601 in another predetermined direction, the locking handle 601 is separated from the side wall, and the functional component 600 is loosened from the trough body 100. At this time, the relative position of the functional component 600 in the trough body 100 can be adjusted along the length direction of the adjustment groove 120, so as to adapt to the lower limb size of the patient. At the same time, the relative angle between the functional component 600 and the trough body 100 can also be adjusted in this loosened state to achieve the effect of making different functional surfaces correspond to the patient's sole.

[0062] The following takes a specific embodiment as an example:

[0063] The cross-sectional shape of the above-mentioned functional component 600 is triangular. Therefore, the functional component 600 includes three functional surfaces provided on the side wall of the functional component 600. For the convenience of distinction, they are named the first functional surface 610, the second functional surface 620, and the third functional surface 630 in this embodiment;

[0064] As Figure 6 shown, a number of convex balls 611 are arrayed and fixed on the first functional surface 610. When the patient's sole contacts the first functional surface 610, relative movement between the sole and the convex balls 611 can be formed in an active or passive manner, so as to achieve the effect of frictional massage. Through the stimulation of the convex balls 611, the perception function of the patient's lower limbs can be promoted to recover, so as to exercise the nerve function of the patient's lower limbs and promote recovery.

[0065] As Figure 7As shown in the figure, a roller 621 is fitted and rotatably arranged on the second functional surface 620. When the patient's sole contacts the second functional surface 620, the joint angle at the ankle can be actively adjusted to exercise the ankle. During this process, the roller 621 has the effect of assisting in supporting and moving the patient's sole, realizing the function of assisting exercise.

[0066] As Figure 8 shown in the figure, a clamping seat 631 is fixedly arranged on the third functional surface 630. Both sides of the clamping seat 631 are bent at a predetermined angle to form a U-shaped limiting structure. The function of the clamping seat 631 is to fix the patient's sole. In some cases, it is necessary to fix the patient's sole during treatment or subsequent recovery to ensure the stable recovery state of other parts of the lower limb. The position of the patient's sole can be restricted through the clamping seat 631, thereby preventing the patient's lower limb from moving. In one embodiment of the present invention, a restraint structure such as a restraint band can also be arranged on the clamping seat 631 to further achieve the function of fixing the sole and lower limb.

[0067] In the above embodiment, since the leg support device with the flap avoidance function of the present invention needs to be reused, in order to avoid discomfort caused by indirect contact between different patients, a dressing layer 201 can be detachably attached to the upper side of the support block 200. The dressing layer 201 adopts the common foam dressing in medical institutions in the prior art, which can directly form a fit with the support block 200 and is convenient for removal. At the same time, it avoids the direct contact between the patient's skin and the leg support device with the flap avoidance function. Other structures of the support device with the flap avoidance function can be made of metal materials that are not easy to rust, so as to facilitate the medical staff to clean and disinfect.

[0068] The dressing layer 201 can also be arranged on the above transition support member 500 to ensure the hygiene when the medical equipment is used crossly.

[0069] In addition, the upper side of the above-mentioned forming block can be inclined at a predetermined angle to form a groove-shaped limiting structure to assist in fixing the patient's lower limb. The specific shape can be set by those skilled in the art according to actual use requirements, and the present application does not limit this.

[0070] Based on the above embodiment, the actual use process of the leg support device with the flap avoidance function of the present invention is as follows:

[0071] As Figure 1 and Figure 2As shown, a leg support device with a flap avoidance function is prepared, a dressing layer 201 is attached to several support blocks 200, and the medical staff determines the specific position of the patient's flap transplantation site, and determines the support block 200 at the corresponding position according to the position. For the adjustment of a single support block 200, the medical staff holds the spherical ends of the locking pieces 210 on both sides with both hands, and pulls to unlock the locking pieces 210 from the slide groove 110 and the gear slot 111, and drags the support block 200 downward while maintaining the force, so that a height difference is formed between the support block 200 and the other support blocks 200, and the locking piece 210 is released after the position is suitable, so that the locking piece 210 is locked with the slide groove 110 and the gear slot 111 at the corresponding position, and the multiple support blocks 200 that need to be adjusted are adjusted in turn so that there is no contact with the patient's flap site, and the support block 200 at one end of the slot body 100 is adjusted to adapt to the length of the patient's lower limb. According to the support angle requirement of the lower limbs, the telescopic rod 410 is adjusted to form a required angle between the slot body 100 and the bottom plate 300, forming a similar Figure 2 The patient's lower limbs can be placed in the style shown.

[0072] After the placement position of the patient's lower limb is determined, the position of the functional part 600 and the orientation and angle of the functional surface are adjusted so that the functional part 600 fits against the sole of the patient's foot to achieve a specific function, thereby completing the use process of the leg support device with a flap avoidance function of the present invention.

[0073] In summary, the present invention provides a leg support device with a flap avoidance function, and the leg support device with a flap avoidance function includes: a slot body, a plurality of support blocks are arranged in parallel and slidingly along the length direction of the slot body, and locking pieces passing through the slot body are respectively arranged at both ends of the support blocks, and the locking pieces are detachably engaged with sliding grooves arranged on the slot body along the height direction of the slot body; a base plate, one end of the base plate is rotatably connected to the bottom of the slot body, and the other end of the base plate is provided with an adjustment component, and the adjustment component is used to fix the relative angle between the base plate and the slot body. The present invention arranges a plurality of support blocks in parallel inside the trough body, and realizes adjustment of different support blocks to different heights by engaging locking pieces on both sides of the support blocks with sliding grooves on the trough body, thereby achieving the effect of supporting the patient's lower limbs while avoiding the flap site, and adjusting for patients of different body shapes. By adjusting the relative angle between the bottom plate and the trough body of the fixed component, the effect of lifting the patient's lower limbs at different angles can be met. The adjustment process does not require the patient to move, and can meet the needs of lifting the patient's lower limbs and avoiding the flap site, thereby creating better conditions for the survival of the flap.
