Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an orthopedic lower limb weight-bearing monitoring tool. Background Art

[0002] The lower limbs are the main part that supports the human body, especially when standing, walking, running and jumping, the weight of the whole body is distributed to the lower limbs through the bones and muscle structures. Because the lower limbs of the human body not only bear most of the body weight and the burden of daily activities, but also the impact and pressure from the outside world will directly act on the lower limbs. At the same time, the lower limbs include multiple complex joints such as the knee joint, ankle joint and hip joint. There are many ligaments, tendons, cartilage and other structures inside the joints. The stability of the joints themselves is relatively complex, making the lower limbs of the human body prone to injuries, such as fractures and dislocations. When the lower limbs of the human body are injured, after treatment with drugs or surgery, the patient's lower limbs need to undergo a series of rehabilitation exercises. During the rehabilitation exercises, the bones, muscles and other tissues of the lower limbs are appropriately stimulated to speed up the recovery of the lower limbs.

[0003] Lower limb rehabilitation exercises generally include the following periods: 1. Initial stage of rehabilitation: mainly starting with non-weight-bearing exercises, the purpose is to restore the range of motion of joints (ROM) and muscles; 2. Partial weight-bearing exercises: allowing the lower limbs to gradually bear part of the body weight, and the patient can gradually increase the weight-bearing ratio, gradually transitioning from 50% to 100%, which helps to gradually strengthen muscles and bones and reduce the risks of full weight-bearing, so as to help patients gradually adapt to the weight-bearing; 3. Full weight-bearing exercises (recovery period): through certain weight-bearing exercises, it can help to enhance lower limb strength, improve bone density, and promote fracture healing; 4. Functional training (late recovery period): through some more challenging functional training, to help patients restore normal life and motor ability of the lower limbs.

[0004] However, during rehabilitation exercises, once the pressure on the patient's lower limbs exceeds their load-bearing capacity, it is very easy to aggravate the condition and cause complications or delay recovery. Especially during partial weight-bearing and full weight-bearing exercise stages, the joints, bones and other tissues of the patient's lower limbs are unstable, and it is necessary to ensure that the patient performs weight-bearing exercises reasonably. In order to ensure the safety of the patient's rehabilitation exercises, orthopedic doctors need to evaluate the patient's lower limb load-bearing capacity, so as to guide the patient to accurately grasp the load-bearing intensity during exercise.

[0005] When evaluating the weight-bearing capacity of a patient's lower limbs, it is necessary to monitor the weight-bearing capacity of the patient's lower limbs regularly. This is usually done using a weight scale. The patient places the foot of the affected lower limb on the scale and the other foot on the ground. The patient gradually shifts the center of gravity to one side of the scale. When the patient feels pain, the number on the scale is the maximum weight-bearing value of the patient's affected lower limb. However, during measurement, the patient needs the support of a caregiver to prevent him from falling, which makes this method of measurement extremely inconvenient. In addition, since the caregiver provides partial support when supporting the patient, the measured value on the scale is often far lower than the patient's actual weight-bearing capacity, which reduces the accuracy of weight-bearing monitoring and makes it difficult to provide effective guidance for the patient's lower limb rehabilitation exercises.

[0006] At present, the existing technology mostly uses professional measuring instruments to replace the weight scale. The measuring instrument mainly includes: a bracket, a pedal and an elastic member. The pedal can move up and down on the bracket. The elastic member provides resistance for the movement of the pedal. The patient is in a sitting state and steps on the foot of the injured lower limb on the pedal, and then continuously pushes the pedal downward until the patient feels pain. The maximum weight value is calculated using the distance the pedal moves downward. The measuring instrument can be measured independently by the patient, while avoiding external factors from interfering with the weight measurement, thereby improving the accuracy of weight monitoring. However, when the weight value obtained by the measuring instrument is used to guide the patient to perform rehabilitation weight-bearing exercises, the patient's lower limbs often cannot adapt to the weight, resulting in increased pain in the patient's lower limbs. After investigation, it was found that when the patient's lower limbs are performing weight-bearing exercises, the lower limbs need to continue to bear the weight, and the weight value obtained by the measuring instrument is the instantaneous maximum pressure on the elastic member when the patient feels pain, resulting in the obtained weight value being greater than the actual weight-bearing capacity of the patient's lower limbs. Therefore, the accuracy of lower limb weight monitoring by existing measuring instruments is limited. Summary of the invention

[0018] The present invention provides an orthopedic lower limb weight monitoring tool, which is combined with Figures 1 to 6The present invention is described with reference to the structural schematic diagram of FIG.

[0019] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] At present, the existing technology mostly uses professional measuring instruments to replace the weight scale. The measuring instrument mainly includes: a bracket, a pedal and an elastic member. The pedal can move up and down on the bracket. The elastic member provides resistance for the movement of the pedal. The patient is in a sitting state and steps on the foot of the injured lower limb on the pedal, and then continuously pushes the pedal downward until the patient feels pain. The maximum weight value is calculated using the distance the pedal moves downward. The measuring instrument can be measured independently by the patient, while avoiding external factors from interfering with the weight measurement, thereby improving the accuracy of weight monitoring. However, when the weight value obtained by the measuring instrument is used to guide the patient to perform rehabilitation weight-bearing exercises, the patient's lower limbs often cannot adapt to the weight, resulting in increased pain in the patient's lower limbs. After investigation, it was found that when the patient's lower limbs are performing weight-bearing exercises, the lower limbs need to continue to bear the weight, and the weight value obtained by the measuring instrument is the instantaneous maximum pressure on the elastic member when the patient feels pain, resulting in the obtained weight value being greater than the actual weight-bearing capacity of the patient's lower limbs. Therefore, the accuracy of lower limb weight monitoring by existing measuring instruments is limited.

[0021] Based on the above problems, an orthopedic lower limb weight-bearing monitoring tool provided by an embodiment of the present invention is used in conjunction with a barrel body, a support plate, an elastic member, a slide bar and a pressure monitoring element on a base. When monitoring the lower limb weight-bearing, the patient's feet step on the two slide bars respectively, and the patient's lower limbs push the slide bar to move downward, so that the slide bar abuts against the lower side of the first slide groove to overcome the resistance of the elastic member, and then swings back and forth alternately to drive the slide bar to move on the support plate, so that the patient's lower limbs are subjected to the same pressure for a certain period of time, and the rebound force of the elastic member is synchronously collected by the pressure monitoring element. When the patient's lower limbs feel pain, the weight-bearing value of the patient's lower limbs is obtained, and at the same time, the slide bar can move downward layer by layer along the first slide groove, thereby gradually increasing the pressure continuously borne by the patient's lower limbs. Each time the patient increases the pressure borne by the lower limbs, the pressure needs to be maintained for a period of time, so that the lower limb weight-bearing value obtained by monitoring is consistent with the patient's actual weight-bearing capacity for rehabilitation exercises, thereby improving the accuracy of the patient's lower limb weight-bearing monitoring, and providing important data support for doctors to guide patients to perform rehabilitation exercises. The weight-bearing monitoring tool of the present invention is easy to use, has good effects, is highly practical, and is worthy of promotion.

[0022] Reference Figure 1 , Figure 1 FIG. 1 is a top view of the lower limb weight-bearing monitoring tool of this embodiment. Figure 1 As shown, an orthopedic lower limb weight monitoring tool includes a base 1, two barrels 2 are respectively fixed vertically on the base 1, two support plates 3 are respectively arranged horizontally in the barrels 2, the support plates 3 are vertically slidably connected to the barrels 2, two elastic members 4 are respectively arranged in the barrels 2 and are located directly below the support plates 3, one end of the elastic member 4 is connected to the support plate 3, and the other end is connected to the inner bottom of the barrel 2 to drive the support plates 3 to move upward, two sliding rods 5 are respectively arranged horizontally on the support plates 3, the two sliding rods 5 are coaxial with each other, the sliding rods 5 are in contact with the support plates 3, and the inner walls of the barrel 2 on both sides near the ends of the sliding rods 5 are vertically connected. A plurality of first slide grooves 21 are opened horizontally at equal intervals, and the ends of adjacent first slide grooves 21 are alternately connected. Both ends of the slide bar 5 extend into the first slide grooves 21, and the outer diameter of the slide bar 5 is smaller than the width of the first slide groove 21. The patient's feet are respectively stepped on the two slide bars 5, and the patient's lower limbs swing alternately to drive the slide bar 5 to move downward layer by layer along the first slide groove 21 to gradually increase the weight of the patient's lower limbs. Two pressure monitoring elements 6 are respectively arranged on the inner bottom of the barrel body 2, and the pressure monitoring element 6 is in contact with the end of the elastic member 4 away from the support plate 3, so as to collect the rebound force of the elastic member 4 to monitor the weight of the patient's lower limbs.

[0023] In this embodiment, the base 1 is placed on the ground, and the patient now places the foot of the uninjured lower limb on the slide bar 5 in one of the barrels 2, and the slide bar 5 is just located at the center of the foot, so that the front sole and the back sole of the foot are in contact with the support plate 3, and then the uninjured foot is used to press the slide bar 5 and the support plate 3 to prop up the body upward, and the foot of the injured lower limb is placed on the slide bar 5 and the support plate 3 in the other barrel 2 in the same way. After the patient is ready, the lower limb pushes the slide bar 5 and the support plate 3 downward to overcome the resistance of the elastic member 4, so that the slide bar 5 abuts against the lower inner wall of the first slide groove 21, and the two lower limbs are swung back and forth alternately. The slide bar 5 is driven to move back and forth on the support plate 3, so that the patient's lower limbs are subjected to the same pressure for a period of time. After the slide bar 5 enters the first slide groove 21 of the next layer, the patient does not feel pain, and the measurement can be continued according to the above process until the patient feels pain when pushing the slide bar 5. The rebound force collected by the pressure monitoring element 6 is the patient's actual weight-bearing capacity. Every time the patient increases the pressure on the lower limbs, the pressure needs to be maintained for a period of time, so that the lower limb weight-bearing value obtained by monitoring is consistent with the patient's actual weight-bearing capacity for rehabilitation exercises, thereby improving the accuracy of monitoring the patient's lower limb weight.

[0024] In this embodiment, when the patient's lower limbs push the sliding bar 5 and feel pain, the patient only needs to lift the lower limbs slightly to separate them from the sliding bar 5. At the same time, the sliding bar 5 will abut against the upper inner wall of the first sliding groove due to the rebound force of the elastic part, thereby preventing the rebound force from impacting the patient's lower limbs when the patient retracts force, thereby improving the safety of lower limb weight monitoring.

[0025] In order to be able to directly view the test pressure value, the load monitoring tool in this embodiment can be provided with an electronic display on the base 1, the electronic display is electrically connected to the pressure monitoring element 6, and the load value is directly displayed by the electronic display.

[0026] Reference Figure 5 , Figure 5 FIG. 1 is an enlarged schematic diagram of the lower limb weight-bearing monitoring tool of this embodiment at position D. Figure 5 As shown, as a further optimization scheme, in this embodiment, a second slide groove 22 is opened on the barrel body 2 on the side of the first slide groove 21 away from the support plate 3. The second slide groove 22 has the same trajectory as the first slide groove 21. Both ends of the slide rod 5 extend into the second slide groove 22 and are respectively fitted with gears 51. A rack 23 is fixed on the upper inner wall of the second slide groove 22 along its trajectory. The rack 23 is meshed with the gear 51. When the slide rod 5 abuts against the lower inner wall of the first slide groove 21, the rack 23 is separated from the gear 51.

[0027] In this embodiment, a second slide groove 22 is provided on the outer side of the first slide groove 21, and the end of the slide rod 5 extends into the second slide groove 22 and is provided with a gear 52. By utilizing the cooperation between the gear 51 and the rack 23 in the second slide groove 22, it can be achieved that when the slide rod 5 is not pushed downward, the gear 52 and the rack 23 can clamp the slide rod 5, thereby preventing the slide rod from being moved even when the pressure on the patient's lower limbs does not reach the set value, thereby preventing the measured weight from being greater than the patient's actual weight-bearing capacity. When the downward thrust applied by the patient's lower limbs causes the slide rod 5 to abut against the lower inner wall of the first slide groove, the gear 51 is separated from the rack 23, and the patient can push the slide rod 5 to move along the first slide groove 21 normally. The weight measured in this state is consistent with the patient's actual weight-bearing capacity, thereby further improving the accuracy of monitoring the patient's lower limb weight.

[0028] As a further optimization scheme, in this embodiment, sliding sleeves 52 are respectively provided on both sides of the sliding rod 5 close to the first sliding groove 21, and the sliding sleeves 52 are rotatably connected to the sliding rod 5 around its circumference. When the sliding sleeve 52 abuts against the lower inner wall of the first sliding groove 21, the rack 23 is separated from the gear 51.

[0029] In this embodiment, a sliding sleeve 52 is provided on the sliding rod 5. When the patient pushes the sliding rod 5 downward and the sliding sleeve 52 abuts against the lower inner wall of the first sliding groove 21, the sliding rod 5 is pushed to move along the first sliding groove 21, thereby avoiding the first sliding rod 5 from getting stuck during the measurement process and improving the stability of lower limb weight monitoring.

[0030] Reference Figure 3 , Figure 3 BB is a cross-sectional view of the lower limb weight-bearing monitoring tool of this embodiment, as shown in Figure 3 As shown, as a further optimization scheme, in this embodiment, the longitudinal sections of the first slide groove 21 and the support plate 3 are both arc-shaped, and their center lines are coaxial with each other, the arc-shaped opening is vertically upward, and a shell 31 is arranged on the support plate 3. The bottom of the shell 31 is arc-shaped and abuts against the upper side of the support plate 3, and the top of the shell 31 is arranged through. The patient's feet are placed in the shell 31, and the slide bar 5 is divided into two sections and respectively arranged on both sides of the shell 31. One end of the slide bar 5 is fixedly connected to the shell 31, and the other end extends into the first slide groove 21.

[0031] In this embodiment, the first slide groove 21 and the support plate 3 are both set to be arc-shaped, and the bottom of the shell 31 is also arc-shaped and abuts against the upper side of the support plate 3. The patient's feet step into the shell 31, and the patient's lower limbs push the shell 3 and the slide bar 5 downward to move. After the sliding sleeve 52 abuts against the lower inner wall of the first slide groove 21, the patient's lower limbs swing back and forth alternately to drive the shell 3 and the slide bar 5 to move along the first slide groove 231, so that the patient's lower limbs can swing back and forth with the hip joint as the node, simulating the patient's posture when running with weight. When the patient's lower limbs do not feel pain at any angle of swinging back and forth, it means that the patient's lower limbs can fully bear the weight, further reducing the occurrence of accidents during rehabilitation exercises, and further improving the accuracy and effect of monitoring the patient's lower limb weight.

[0032] As a further optimization scheme, in this embodiment, an arc-shaped slide groove 32 is opened on the upper side of the support plate 3, and the arc-shaped slide groove 32 is coaxial with the center line of the first slide groove 21. A ball 33 is provided at the bottom of the shell 31, and the ball 33 is slidably connected to the shell 31, and the ball 33 is embedded in the arc-shaped slide groove 32.

[0033] In this embodiment, the arc groove 32 on the support plate 3 is used in conjunction with the ball 33 at the bottom of the shell 31 to improve the stability of the shell 31 and the slide rod 5 moving along the first groove 21 after the patient's lower limbs push the shell 31 downward.

[0034] Reference Figure 2 , Figure 2 AA is a cross-sectional view of the lower limb weight-bearing monitoring tool of this embodiment, as shown in Figure 2 As shown, as a further optimization scheme, in this embodiment, a connecting tube 34 is vertically fixed in the middle of the bottom of the support plate 3, and a column 35 is vertically fixed to the inner bottom of the barrel body 2. The column 35 extends into the connecting tube 34 and is slidably connected to the connecting tube 34 along the length direction. The pressure monitoring element 6 is fixed at the top of the column 35, and the elastic member 4 is a spring, which is arranged in the connecting tube 34, one end of the spring abuts against the bottom of the support plate 3, and the other end abuts against the pressure monitoring element 6.

[0035] In this embodiment, by using the connecting tube 34, the column 35 and the spring together, the patient's lower limbs can push the shell 31 downward to overcome the resistance of the spring, and stably transmit the pressure to the pressure monitoring element 6, thereby reducing the impact of external factors on the accuracy of weight monitoring.

[0036] As a further optimization scheme, in this embodiment, a cross bar 7 is horizontally arranged between the two barrel bodies 2, the cross bar 7 and the connecting tube 34 are perpendicular to each other, and support rods 8 are vertically arranged at both ends of the cross bar 7, one end of the support rod 8 is connected to the cross bar 7, and the other end is connected to the barrel body 2.

[0037] In this embodiment, a handrail is formed by a cross bar 7 and a support bar 8 between the two barrels 2, which facilitates the patient to put the lower limbs into the shell 3 and get off the monitoring tool, and at the same time ensures the stability of the patient's body during the load-bearing capacity test.

[0038] Reference Figure 4 , Figure 4 : is a CC cross-sectional view of the lower limb weight-bearing monitoring tool of this embodiment, as shown in Figure 4 As shown, as a further optimization scheme, in this embodiment, a third slide groove 24 is vertically opened on the side where the two barrel bodies 2 are close to each other, one end of the support rod 8 is hinged to the cross bar 7, and the other end is provided with an L-shaped connecting rod 25, the vertical end of the L-shaped connecting rod 25 is fixedly connected to the support rod 8, and the horizontal section thereof passes through the third slide groove 24 and extends into the barrel body 2, and the horizontal end of the L-shaped connecting rod 25 is fixedly connected to the lower side of the connecting tube 34.

[0039] In this embodiment, the third slide groove 24 on the barrel body 2 is utilized. When the patient's lower limbs continuously push the slide bar to move downward layer by layer along the first slide groove, the cross bar 7 can also move downward synchronously. The patient holds the cross bar 7 with his hands to maintain body balance, avoiding upward support for the patient, thereby further improving the accuracy of monitoring the patient's lower limb weight.

[0040] In the present embodiment, when the patient is performing lower limb weight-bearing monitoring, no matter one lower limb is injured or both lower limbs are injured and weight-bearing monitoring is required, the patient's two lower limbs alternately push the slide bar to move downward layer by layer along the first slide groove (that is, when one lower limb is not injured, the same action as the injured lower limb on the other side is required to keep the cross bar 7 balanced).
