Description

TECHNICAL FIELD

[0001] The present application belongs to the field of medical devices, and more particularly relates to a device for measuring the height of a calf raise after Achilles tendon rupture repair. BACKGROUND

[0002] In recent years, the number of patients with Achilles tendon rupture and Achilles tendon end disease continues to increase, among which acute Achilles tendon rupture is usually high in male sports enthusiasts, and Achilles tendon end disease is more common in athletes, dancers and long-term overuse groups. As the strongest tendon in the human body, the Achilles tendon can withstand a load of up to 12 times the body weight when walking or running. Once it is ruptured or has end disease, it often leads to plantar flexion weakness, difficulty in kicking, and even inability to complete the calf raise, significantly limiting daily activities and work capacity. Acute rupture is often accompanied by severe pain and local depression; end disease is characterized by morning stiffness, chronic pain that worsens after activity, and advanced calcification or bone spur formation that further damages the tendon structure; in addition, patients also face the risk of muscle atrophy, traumatic arthritis, Achilles tendon shortening or adhesion, and other complications.

[0003] Such patients generally have poor prognosis. Although structural healing can be achieved through surgery or conservative treatment, a small number of patients still have long-term ankle stiffness or limited mobility. The re-rupture rate after conservative treatment is higher than that after surgical treatment, and the Achilles tendon may heal in an extended state, leading to loss of strength and gait abnormalities. Among the patient's prognosis, the calf raise ability is particularly poor, as the mechanical properties of the Achilles tendon decrease (such as reduced shear resistance and abnormal viscosity) and the triceps surae muscle atrophies, resulting in a significant decrease in calf raise height and endurance.

[0004] For such patients, the patient's calf raise ability needs to be recorded during re-examination. In related technology, a ruler method or a laser range finder is usually used for measurement. However, after a period of time after surgery, patients often have lower limb muscle atrophy and wound pain, resulting in decreased calf raise ability, low calf raise height, and short calf raise maintenance time. When using a ruler method or a laser range finder to measure the calf raise height of these patients, it is difficult to accurately measure the reading within the patient's short calf raise time, and it is also difficult to ensure that the ruler is completely perpendicular to the ground, resulting in inaccurate readings and measurement errors.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0023] The present application discloses a heel height measuring device for Achilles tendon rupture repair, which can accurately and quickly read the ankle heel height compared with the traditional ruler method or the use of laser range finder measurement, solves the problems of poor ankle heel ability of patients with Achilles tendon rupture after operation, short heel time, difficulty in measuring ankle heel height, and cannot guarantee perpendicularity with the ground when using a ruler to measure the heel height, and the naked eye reading is not accurate.

[0024] Referring to Figures 1-4 The heel height measuring device specifically comprises a shell body 1, a contact detection rod 2, a contact sensing panel 3, a digital display panel 4 and a reset assembly 5, wherein the shell body 1 serves as the bearing matrix of the whole measuring device, the contact detection rod 2, the contact sensing panel 3, the digital display panel 4 and the reset assembly 5 are all installed on the shell body 1; one end of the contact detection rod 2 directly contacts the heel and can be pushed to displace for real-time sensing of the heel height; the contact detection rod 2 contacts the contact sensing panel 3 after displacement, the contact sensing panel 3 can convert the displacement of the contact detection rod 2 into an electrical signal, the contact sensing panel 3 is a commonly used component in the art, which can trigger a response after receiving pressure, and an electrical signal is generated after the corresponding height sensor in the contact sensing panel 3 responds; the digital display panel 4 is electrically connected with the contact sensing panel 3, and the digital display panel 4 can display the heel height value in real time after receiving the electrical signal transmitted by the contact sensing panel 3; the reset assembly 5 can reset the contact detection rod 2 after displacement, so that the digital display returns to zero after one measurement, facilitating re-measurement.

[0025] Specifically, the shell body 1 is horizontally placed in use, and a plurality of installation channels 11 are formed through the shell body 1 in the horizontal direction. The front end of the shell body 1 is the front end of the installation channels 11. When the device is in use, the front end of the shell body 1 faces the heel of the patient, and the rear end of the shell body 1 is the rear end of the installation channels 11. The number of contact detection rods 2 is also set to be the same as the number of installation channels 11. The plurality of contact detection rods 2 are respectively and one-to-one installed in the installation channels 11. The axis direction of the contact detection rod 2 is the same as the arrangement direction of the installation channel 11, and the contact detection rod 2 can be movably arranged in the axial direction. The inner diameter of the installation channel 11 is slightly larger than the diameter of the contact detection rod 2, so that the contact detection rod 2 can smoothly move in the axial direction and will not shake greatly. The plurality of contact detection rods 2 are arranged densely, so that the plurality of contact detection rods 2 at the same height can be simultaneously contacted with the heel and be pushed to be displaced, to ensure that the contact sensing panel 3 accurately senses, so that the digital display panel 4 can display the accurate heel-lifting height. The measurement device is designed by the structure of dense array and multi-rod synchronous triggering. When the heel is lifted, the plurality of contact detection rods 2 at the same height are simultaneously pushed, a plurality of point synchronous signals are generated, the height value is output by the digital display panel 4 after being collected by the contact sensing panel 3, and the measurement accuracy and repeatability are improved.

[0026] Reference Figures 5-6 More specifically, the contact detection rod 2 is of a segmented structure, which includes a panel contact section 21 and a foot contact section 22. The end of the panel contact section 21 is a panel contact end, which cooperates with the contact sensing panel 3. The end of the foot contact section 22 is a foot contact end 221, which is a smooth round end and directly contacts the heel. The panel contact end of the contact detection rod 2 is located inside the shell body 1, and the foot contact end 221 of the contact detection rod 2 is located outside the shell body 1. The panel contact section 21 and the foot contact section 22 are detachably connected, so as to facilitate the installation, disassembly and replacement of the contact detection rod 2 in the measurement device. The panel contact section 21 and the foot contact section 22 are detachably connected by a threaded connection. In other embodiments, the panel contact section 21 and the foot contact section 22 can also be detachably connected by magnetic attraction.

[0027] Further, the contact sensing panel 3 is vertically fixedly connected to the shell body 1 and located at the rear end of the mounting channel 11, and a buffer protection layer is arranged on the contact surface of the contact sensing panel 3, when any contact detection rod 2 moves a distance to the rear end of the mounting channel 11, the panel contact end thereof abuts against the contact sensing panel 3, and the buffer protection layer can effectively reduce the pressure of the contact detection rod 2 on the contact sensing panel 3, so as to prolong the service life of the contact sensing panel 3. The digital display panel 4 is fixedly installed on the shell body 1 or the contact sensing panel 3, or the digital display panel 4 is installed on both the shell body 1 and the contact sensing panel 3, so that the measurer can read from different angles, and after the overall installation of the measuring device, the digital display panel 4 is electrically connected with the contact sensing panel 3, when the contact detection rod 2 contacts the contact sensing panel 3, the contact sensing panel 3 can obtain the reading of the height at which the corresponding contact detection rod 2 is located, and the reading is displayed on the digital display panel 4 for reading, and when multiple contact detection rods 2 contact the contact sensing panel 3, the maximum reading is taken as the display reading on the display panel, that is, the heel height. When the patient lifts the heel, the rear malleolus heel is the most protruding point of the patient's sagittal plane, and after moving the overall measuring device to make the several contact detection rods 2 contact the heel, the contact detection rod 2 corresponding to the rear malleolus heel is pushed and triggers the contact sensing panel 3, and the digital display panel 4 instantly displays the corresponding height data, so as to read the ankle heel height, and the reading is the height of the height of the sensing panel perpendicular to the ground, after the detection is completed, the overall measuring device is removed, and the reset assembly 5 can reset the pushed contact detection rod 2, so as to be used again, that is, the reset assembly 5 can drive the contact detection rod 2 to move away from the contact sensing panel 3.

[0028] Referring to Figure 4 In order to prevent the contact detection rod 2 from being pulled out of the mounting channel 11, in the embodiment, a limiting cavity 12 communicating with the mounting channel 11 is formed in the shell body 1 near the rear end of the mounting channel 11, and the panel contact end of the contact detection rod 2 is located in the limiting cavity 12, the panel contact end is provided as an integral first ball 211, and the diameter of the first ball 211 is greater than the inner diameter of the mounting channel 11, the first ball 211 is always located in the limiting cavity 12, and the limiting of the overall contact detection rod 2 is realized through the first ball 211, so that the contact detection rod 2 can freely slide in the axial direction under the action of the reset assembly 5, but will not be pulled out of the mounting channel 11.

[0029] Referring to Figure 4Further, the shell body 1 is internally provided with an installation cavity 13 communicated with the installation channel 11, the installation cavity 13 is located at the middle of the installation channel 11, the contact detection rod 2 penetrates the installation cavity 13 and a part of the contact detection rod 2 in the installation cavity 13 is fixedly connected with a second ball 222, the second ball 222 is integrally formed on the foot contact section 22 of the contact detection rod 2, a reset assembly 5 is arranged in the installation cavity 13 and acts on the second ball 222, in the embodiment, the reset assembly 5 comprises a reset plate 51 and a reset spring 52, the reset plate 51 is arranged in the installation cavity 13, a plurality of through holes for the contact detection rod 2 to penetrate are arranged on the reset plate 51, and the diameter of the through holes is smaller than the diameter of the second ball 222, so that the reset plate 51 can effectively act on the second ball 222, the second ball 222 is located at the side of the reset plate 51 close to the front end of the installation channel 11, the reset spring 52 is arranged at least four, and is arranged at the four corners of the reset plate 51, the reset spring 52 is fixedly connected between the reset plate 51 and the inner wall of the installation cavity 13, and drives the reset plate 51 and the second ball 222 to move away from the contact sensing panel 3 by elastic force.

[0030] In the embodiment, one end of the reset spring 52 is fixedly connected to the reset plate 51, the other end is fixedly connected to the side of the installation cavity 13 close to the contact sensing panel 3, the side of the reset plate 51 away from the reset spring 52 is fixedly connected with a damping piece to reduce the impact force during resetting, when the contact detection rod 2 is subjected to the foot pushing force, the second ball 222 drives the reset plate 51 to compress the reset spring 52, when the pushing force disappears, the reset plate 51 and the contact detection rod 2 are reset under the elastic force of the reset spring 52, the distance between the reset plate 51 and the contact sensing panel 3 when being compressed to the limit is equal to the distance between the first ball 211 and the second ball 222, so that the contact detection rod 2 just touches the contact sensing panel 3 when the reset spring 52 is compressed to the limit, and the contact detection rod 2 touching the contact sensing panel 3 too much is avoided to interfere with the reading.

[0031] Referring to Figure 3More specifically, in order to facilitate the maintenance of the measuring device, the shell body 1 comprises a first mounting member 14, a first annular connecting member 15, a second mounting member 16 and a second annular connecting member 17 arranged in sequence along the horizontal direction, the first mounting member 14 and the second mounting member 16 are detachably connected with the first annular connecting member 15, the inside of the first annular connecting member 15 is provided with a cavity to form an installation cavity 13, the second mounting member 16 and the contact sensing panel 3 are detachably connected with the second annular connecting member 17, the inside of the second annular connecting member 17 is provided with a cavity to form a limiting cavity 12, the first mounting member 14 and the second mounting member 16 are both solid bodies provided with a plurality of through holes, and the through holes on the same axis on the first mounting member 14 and the second mounting member 16 jointly form an installation channel 11. The side of the first mounting member 14 and the second mounting member 16 close to each other is integrally formed with a first stepped groove, the first annular connecting member 15 is sleeved outside the first stepped groove and fixed by screws, the side of the second mounting member 16 and the contact sensing panel 3 close to each other is integrally formed with a second stepped groove, the second annular connecting member 17 is sleeved outside the second stepped groove and fixed by screws, and after the first mounting member 14, the first annular connecting member 15, the second mounting member 16, the second annular connecting member 17 and the contact sensing panel 3 are connected in sequence, the overall assembly of the measuring device is completed, and the outer surface forms a continuous and smooth whole. The modular assembly structure of the measuring device makes the device easy to disassemble and reassemble, and facilitates later calibration and maintenance.

[0032] When the patient performs the heel height measurement, the patient stands back to the measuring device, and when the patient lifts the heel, the device is placed horizontally on the ground and then pushed slowly to the back ankle. Since the heel is the most protruding point of the sagittal plane, the contact detection rod 2 corresponding to the heel is first pushed to the back contact sensing panel 3, the contact sensing panel 3 immediately triggers a signal, and the digital display panel 4 generates a reading. The digital display panel 4 can instantaneously output the vertical distance between the contact point and the ground, which is the heel height of the ankle on that side. The device can complete the reading and automatically reset in an instant through multiple independent detection and elastic reset, support continuous multiple measurements, avoid errors caused by angle deviation and time delay in traditional ruler measurement or laser ranging, and provide objective and repeatable height data for ankle heel height measurement. As shown in FIG. Figure 7 When the measuring device is in use, the contact detection rod 2 at a height of 12 cm contacts the contact sensing panel 3 after being moved by the pushing force of the heel, at which time the digital display panel 4 displays a reading of 12 cm. It can be seen that the ankle heel height measurement this time is 12 cm, and according to the measurement data, the recovery degree diagnosis of the patient can be facilitated.
