Description

Technical Field

[0001] This invention relates to the medical field, specifically to a medical orthopedic examination leg posture adjustment device. Background Technology

[0002] Orthopedics primarily studies the anatomy, physiology, and pathology of the musculoskeletal system, using medication, surgery, and physical methods to maintain and develop the normal morphology and function of this system. Orthopedics is an essential outpatient department in all types of hospitals and is a relatively common outpatient department. The most common method of leg orthopedic examination is to examine the patient's legs. In modern life, most examinations involve placing the patient's legs on a fixed table or chair and then having medical staff examine the leg posture. This method is not conducive to the examination by medical staff and makes it difficult to adjust the patient's leg posture. Using medical orthopedic examination leg posture adjustment equipment can facilitate the examination by medical staff.

[0003] The currently disclosed Chinese patent CN202011234361.4 discloses a medical orthopedic examination leg posture adjustment device, including a base and a support block. The base has a rectangular groove on its side wall, and a cover plate is sealed against the inner wall of the rectangular groove. The upper end of the base has a placement groove, and a rectangular block is slidably connected to the inner wall of the placement groove. A sliding cavity is formed on the side wall of the rectangular block, and a sliding plate is slidably connected to the inner wall of the sliding cavity. Multiple guide rods are welded to the upper end of the sliding plate, and all guide rods penetrate the inner top of the sliding cavity. All guide rods are slidably connected to the rectangular block, and the upper ends of the multiple guide rods are welded together. The support block is equipped with a support plate. A rotating groove is formed at the bottom of the support block, and a deep groove ball bearing is welded to the inner wall of the rotating groove. A connecting block is welded to the inner wall of the deep groove ball bearing. A threaded groove is formed at the bottom of the connecting block, and a threaded rod is rotatably connected to the inner wall of the threaded groove. The bottom of the threaded rod is welded to the upper end of the support plate. The upper end of the support block is arc-shaped inwards. A protective layer made of rubber is glued to the upper end of the support plate. An adjustment device is provided inside the rectangular block. A winding device is provided on the side wall of the support block. Two symmetrically arranged quick-installation devices are provided at the upper end of the base.

[0004] According to the aforementioned patent, the height of the leg can be adjusted. However, the adjustment range of the leg height is limited.

[0039] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0040] See Figures 1-10 As shown, a medical orthopedic examination leg posture adjustment device is installed on a seat 1, including a pair of swing frames 2, which are symmetrically arranged in front of the seat 1. Each swing frame 2 is provided with a slider 3, a locking member 4, and a position adjustment mechanism 5. The slider 3 is slidably arranged on the swing frame 2. The locking member 4 is arranged on the slider 3. The position adjustment mechanism 5 is arranged on the swing frame 2 and is connected to the slider 3. A swing drive assembly 6 is installed at the bottom of the seat 1 at the position of each swing frame 2, and each swing frame 2 is connected to the corresponding swing drive assembly 6.

[0041] When the doctor examines the patient's legs, the patient sits in chair 1 with their knees bent and resting on the front of chair 1. The patient's legs are secured by locking device 4. The doctor adjusts the position of sliding device 3 on the swing frame 2 according to the length of the patient's legs. During the process of securing the patient's legs, the swing frame 2 is in a vertical position, and the sliding device 3 is adjusted to the appropriate position. The locking device 4 is also adjusted to the appropriate position along with the sliding device 3. Then, the patient's legs are secured within the locking device 4. However, the doctor activates the swing drive assembly 6. Under the drive of the swing drive assembly 6, the swing frame 2... The swing frame 2 swings upwards within a 90° range. The doctor controls the start and stop of the swing drive component 6, which allows for examination of the patient's legs in different postures. When the patient's legs are adjusted from a drooping position to a straight position, the swing drive component 6 automatically stops, and the swing frame 2 reaches the end of its swing. Since the part of the patient's leg that is fixed by the locking part 4 cannot be examined, the doctor needs to adjust the position of the locking part 4 on the patient's leg by controlling the position adjustment mechanism 5, so that the unexamined part is exposed, achieving the effect of comprehensive examination.

[0042] See Figures 4-8 As shown, the swing frame 2 includes a support cylinder 2a, a hinge block 2b, and a hinge plate 2c. The support cylinder 2a is horizontally positioned at the front of the seat 1, and the seat 1 has an insertion opening for mounting the support cylinder 2a. The surface of the support cylinder 2a is flush with the upper surface and front of the seat 1. There are two hinge blocks 2b, which are symmetrically arranged at both ends of the support cylinder 2a. Each hinge block 2b is fixedly connected to the seat 1. There are two hinge plates 2c, each of which is connected to one hinge block 2b. One end of the hinge plate 2c is hinged to the hinge block 2b, and the other end of the hinge plate 2c is connected to the swing drive assembly 6. The two hinge plates 2c are arranged parallel to each other, and the locking member 4 is installed between the two hinge plates 2c.

[0043] After the patient sits on the seat 1, the patient places their legs between the two hinge plates 2c, with the patient's bent knee resting on the support cylinder 2a. Then, the patient's legs are fixed by the locking member 4, and the swing drive assembly 6 drives the two hinge plates 2c to rotate on the corresponding hinge block 2b, thus completing the adjustment of the patient's leg posture.

[0044] See Figure 8As shown, the sliding member 3 includes a sliding plate 3a, a first sliding sleeve 3b, and a fixing clip 3c; there are two sliding plates 3a, each of which is mounted on a hinge plate 2c and is located between the two hinge plates 2c; there are two pairs of first sliding sleeves 3b, each pair of first sliding sleeves 3b is slidably mounted on a hinge plate 2c, and each sliding plate 3a is fixedly mounted on the corresponding two first sliding sleeves 3b; there are two fixing clips 3c, each of which is mounted on a sliding plate 3a, and a locking member 4 is installed between the two fixing clips 3c.

[0045] When the doctor adjusts the locking member 4 to fix the position of the patient's leg using the slider 3, the doctor manually moves the slide plate 3a. The slide plate 3a slides on the hinge plate 2c through the first sliding sleeve 3b. After adjusting to the appropriate height, the doctor uses the position adjustment mechanism 5 to maintain the position of the slide plate 3a to prevent it from sliding down. The locking member 4 is installed between the two fixing clamps 3c. The patient's leg passes through the two fixing clamps 3c and is thus fixed by the locking member 4.

[0046] See Figure 8 As shown, the locking component 4 includes a ring 4a and an airbag 4b; the ring 4a is fixedly disposed between two fixing clamps 3c, and the axial direction of the ring 4a is perpendicular to the axial direction of the support cylinder 2a; the airbag 4b is disposed in the inner ring of the ring 4a, and an air port 4a1 for air supply to the airbag 4b is provided on the ring 4a.

[0047] When the locking element 4 secures the patient's leg, air is pumped into the air inlet 4a1 via the existing air pump, causing the airbag 4b to expand. The expanded airbag 4b then compresses the patient's leg, thus holding it tightly. Since the airbag 4b is made of flexible material, it will not cause any harm to the patient's leg.

[0048] See Figures 8-10 As shown, the position adjustment mechanism 5 includes a second sliding sleeve 5a, a support roller 5b, and a connecting member 5c; there are two second sliding sleeves 5a, which are slidably mounted on a hinge plate 2c, and each second sliding sleeve 5a is located below a corresponding first sliding sleeve 3b; there are two support rollers 5b, which are respectively mounted on a hinge plate 2c, and each second sliding sleeve 5a is supported on a corresponding support roller 5b; the connecting member 5c is disposed between the two hinge plates 2c, and each second sliding sleeve 5a and its adjacent first sliding sleeve 3b are connected to the connecting member 5c.

[0049] After the sliding member 3 is adjusted to the appropriate position, the doctor installs the support roller 5b onto the hinge plate 2c to support the sliding member 3. Since there is a second sliding sleeve 5a between the first sliding sleeve 3b and the support roller 5b, after the support roller 5b supports the second sliding sleeve 5a, the first sliding sleeve 3b is also supported on the second sliding sleeve 5a, and the position of the locking member 4 is maintained. When the doctor examines the part of the patient's leg that is fixed by the locking member 4, the doctor controls the connecting member 5c to raise the sliding member 3 upward again, so that the first sliding sleeve 3b gradually moves away from the second sliding sleeve 5a, and the part of the patient that has not been examined is exposed, and the doctor then examines that part.

[0050] See Figures 8-10 As shown, each hinge plate 2c has several first insertion holes 2c1 evenly spaced along its length direction. Each support roller 5b is fixed to the hinge plate 2c by a first positioning pin 5b1 cooperating with the corresponding first insertion hole 2c1.

[0051] When the support roller 5b is fixed in position on the hinge plate 2c, since the hinge plate 2c has several first insertion holes 2c1, after the support roller 5b is placed at the position corresponding to the second sliding sleeve 5a, the doctor then inserts the first positioning pin 5b1 through the support roller 5b into the first insertion hole 2c1, and the support roller 5b is fixed on the hinge plate 2c, thereby ensuring the support of the sliding member 3.

[0052] See Figures 8-10 As shown, each hinge plate 2c has several second insertion holes 2c2 evenly spaced along its length. The several first insertion holes 2c1 and several second insertion holes 2c2 are interleaved. Each first sliding sleeve 3b supported on the corresponding second sliding sleeve 5a is fixed to the hinge plate 2c by a second positioning pin 3b1 cooperating with the corresponding second insertion hole 2c2.

[0053] After the position of the slider 3 is adjusted again, the doctor inserts the second positioning pin 3b1 through the first sliding sleeve 3b into the corresponding second insertion hole 2c2, so that the first sliding sleeve 3b will not slide down, and the part of the patient's leg that has not been examined is exposed, which makes it easier for the doctor to examine.

[0054] See Figures 8-10As shown, the connector 5c includes a handle 5c1, a first link 5c2, and a second link 5c3. The handle 5c1 is horizontally positioned on the outer side between the two hinge plates 2c. There are two first links 5c2, each mounted on a first sliding sleeve 3b. One end of each first link 5c2 is axially connected to the corresponding first sliding sleeve 3b, and the other end of each first link 5c2 is axially connected to the end of the handle 5c1. There are two second links 5c3, each mounted on a second sliding sleeve 5a. One end of each second link 5c3 is axially connected to the corresponding second sliding sleeve 5a, and the other end of each second link 5c3 is axially connected to the end of the handle 5c1.

[0055] When the doctor adjusts the position of the slider 3 through the connector 5c, the doctor holds the handle 5c1 and pushes the handle 5c1 toward the hinge plate 2c. Since the first link 5c2 and the second link 5c3 connect the first sliding sleeve 3b and the second sliding sleeve 5a together, the second sliding sleeve 5a is pressed on the support roller 5b, while the first sliding sleeve 3b is pushed upward. After the first sliding sleeve 3b is positioned again by the second positioning pin 3b1, the positioned part of the patient's leg is exposed.

[0056] See Figure 6 and Figure 7 As shown, the swing drive assembly 6 includes a slide rail 6a, a slider 6b, and a push rod 6c. There are two slide rails 6a, each positioned below a hinge plate 2c, horizontally positioned between them. The length direction of each slide rail 6a is perpendicular to the axis of the hinge point of the hinge plate 2c. The slider 6b is slidably positioned between the two slide rails 6a. There are two push rods 6c, symmetrically positioned at both ends of the slider 6b. One end of each push rod 6c is hinged to the end of the slider 6b, and the other end of each push rod 6c is hinged to the lower end of the corresponding hinge plate 2c. A lead screw slide 6d for driving the slider 6b is installed between the two slide rails 6a.

[0057] When the doctor controls the swing drive assembly 6 to swing the hinge plate 2c, the lead screw slide 6d drives the slider 6b to slide on the slide rail 6a. As the slider 6b moves, the push rod 6c pushes the hinge plate 2c to swing upward until it is adjusted to a suitable position for the doctor's examination.

[0058] See Figure 7 As shown, the length of push rod 6c is equal to the length of hinge plate 2c. When hinge plate 2c is in a horizontal state, push rod 6c and hinge plate 2c remain perpendicular to each other.

[0059] When the push rod 6c pushes the hinge plate 2c to swing, since the push rod 6c and the hinge plate 2c are of the same length and the slide rail 6a is located at the bottom when the hinge plate 2c is in a drooping state, the hinge plate 2c will remain in a horizontal state until the push rod 6c is in a vertical state, thus ensuring the comprehensiveness of the patient's leg posture adjustment.

[0060] This application enables doctors to perform a comprehensive examination of the patient's legs by using the swing drive component 6 to drive the swing frame 2 and the position adjustment mechanism 5 to adjust the position of the locking member 4, thereby avoiding insufficient examination and improving the examination effect.

[0061] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
