Description

Technical Field

[0001] The invention relates to medical related fields, in particular to a chair mechanism of a medical spine correction machine. Background Art

[0002] Spinal curvature is an orthopedic disease that is difficult to cure quickly. The most common symptom is abnormal kyphosis of the thoracic spine, commonly known as hunchback. The most common type of hunchback is active kyphosis which can be corrected. Active kyphosis mainly includes postural kyphosis caused by long-term poor sitting posture, paralytic kyphosis caused by trunk muscle weakness due to disease, and compensatory kyphosis secondary to excessive lumbar lordosis. In addition to damaging the human body's appearance, hunchback also brings a lot of inconvenience to daily life.

[0003] When receiving treatment through a spinal correction machine, the patient is usually required to sit with the waist straightened;

[0004] Most of the seat mechanisms on the market are close to the main body of the spinal correction machine, which makes it very inconvenient for patients to adjust their position after sitting. In addition, the people who need treatment are different, and their heights and weights are also different, which makes the fixed seat mechanism more limited. Usually, the height of the seat mechanism is adjusted in reverse so that the patient can be treated in the correct position. The seat mechanism adjustment process is relatively cumbersome and is usually completed by medical staff, which increases the workload of medical staff.

[0005] In this regard, the present application provides a chair mechanism for a medical spine correction machine. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0039] See also Figure 1-7 In an embodiment of the present invention, a chair mechanism of a medical spine correction machine comprises a base 1 and a spine correction machine installation position 2 arranged at a side end of the base 1, and a notch 11 is provided on a side of the base 1 away from the spine correction machine installation position 2;

[0040] A receiving plate 4 is slidably installed in the base 1 through a guide member, a support plate 5 is installed on the receiving plate 4 through a lifting structure, a correction auxiliary structure is installed on the support plate 5, and the lifting structure is connected to a driving structure installed on the receiving plate 4.

[0041] The lifting structure includes two sets of symmetrically arranged lifting members installed on the receiving plate 4;

[0042] The lifting member comprises two lifting plates 33 connected in rotation, and first guide blocks 12 are rotatably mounted at both ends of the two lifting plates 33, and the first guide blocks 12 are slidably matched with second guide grooves 17 provided on the opposite side of the receiving plate 4 and the supporting plate 5, and one group of two first guide blocks 12 at the bottom is fixed to another group of two first guide blocks 12 at the bottom through the connecting plate 13;

[0043] The two connecting plates 13 are both fixedly mounted with a second threaded sleeve 22, and the receiving plate 4 is rotatably mounted with a bidirectional screw rod 14 threadably matched with the two second threaded sleeves 22, and the bidirectional screw rod 14 is connected to the driving structure;

[0044] Furthermore, when the driving structure is working, the bidirectional screw rod 14 is driven to rotate, and when the bidirectional screw rod 14 rotates, it cooperates with the second threaded sleeve 22 to drive the two connecting plates 13 to move relative or oppositely;

[0045] When the connecting plate 13 moves, the first guide block 12 fixed thereto follows the movement, thereby driving the four first guide blocks 12 at the bottom to move relatively, so as to lift the support plate 5 through the lifting plate 33;

[0046] The lifting and lowering of the lifting plate 33 adopts the scissor lift principle in the prior art.

[0047] The correction auxiliary structure includes two symmetrically arranged sleeve plates 6 fixedly mounted on the support plate 5, and a slide plate 7 is slidably mounted inside the sleeve plate 6. A baffle plate 8 is hinged on one of the slide plates 7, and a clamping piece that cooperates with the baffle plate 8 is mounted on the other slide plate 7. A distance detection piece is installed at the bottom of the slide plate 7.

[0048] The engaging member includes two symmetrically arranged mounting tubes 23 fixedly mounted on one of the slides 7, each of which has a clamping block 25 slidably mounted therein, a spring 24 fixed to the end of the clamping block 25, a side of the spring 24 away from the clamping block 25 being fixed to the bottom of the mounting tube 23, and a clamping groove 26 cooperating with the clamping block 25 being provided on the baffle plate 8.

[0049] Furthermore, when the baffle plate 8 is flipped, the two support plates 5 are driven to move in opposite directions by the baffle plate 8, and the spring 24 is compressed at the same time, so that the spring 24 reserves a certain amount of elastic potential energy. When the baffle plate 8 is flipped to the end of the stroke, the card slot 26 is concentric with the card block 25, and the card block 25 is driven to return to the inner side of the card slot 26 by releasing the elastic potential energy stored in the spring 24 to limit the baffle plate 8.

[0050] When the baffle plate 8 is subjected to a relatively large turning force in the opposite direction, the support plate 5 will be driven to give way, so that the baffle plate 8 can turn in the opposite direction;

[0051] It should be noted that when adjusting the height of the baffle 8, force needs to be applied from the side away from the engaging member.

[0052] Furthermore, when the patient sits on the support plate 5, the baffle plate 8 is turned over, and the baffle plate 8 is limited by the engaging member, and then the baffle plate 8 is adjusted to the chest, so that the patient's waist is straightened, which is conducive to the treatment of the spinal correction machine;

[0053] When the patient adjusts the height, the distance detection element detects the sitting height of the patient after the adjustment is completed.

[0054] The driving structure includes a motor 16 fixedly mounted on the receiving plate 4 , and an output shaft of the motor 16 is connected to the bidirectional screw rod 14 via a first transmission belt 15 .

[0055] Furthermore, when the motor 16 is working, the output shaft drives the bidirectional screw rod 14 to rotate clockwise or counterclockwise through the first transmission belt 15;

[0056] Among them, the motor 16 in this embodiment adopts a servo motor that rotates forward and reverse. Of course, a DC motor or a stepper motor can be selected according to actual production needs, and this application does not make specific limitations.

[0057] The base 1 is provided with a mounting groove 20 , and a pushing structure is installed inside the mounting groove 20 . The pushing structure is connected to the lifting structure through a transmission structure.

[0058] The pushing structure includes a screw rod 9 rotatably installed in the installation groove 20, the screw rod 9 is threadedly matched with a first threaded sleeve 10 at the bottom of the receiving plate 4, and the screw rod 9 is connected to the bidirectional screw rod 14 through a transmission structure.

[0059] Furthermore, when the bidirectional screw 14 rotates, the support plate 5 is driven to be lifted. At the same time, the screw 9 is driven to rotate through the transmission structure. When the screw 9 rotates, it drives the receiving plate 4 to move horizontally through the cooperation with the first threaded sleeve 10.

[0060] The transmission structure includes a second transmission rod 27 rotatably mounted in the mounting groove 20 , a transmission sleeve 30 slidably matched with the second transmission rod 27 is sleeved on the second transmission rod 27 , and the transmission sleeve 30 is connected to the screw rod 9 through a differential.

[0061] The differential member includes a gear 31 coaxially fixed on the screw rod 9, and the gear 31 cooperates with a gear set 32 ​​coaxially fixed on the transmission sleeve 30;

[0062] The gear set 32 ​​includes a plurality of driving gears fixed on the transmission sleeve 30 at equal intervals, and the number of teeth of the plurality of driving gears is arranged in an increasing manner.

[0063] Furthermore, the gear set 32 ​​is respectively a first driving wheel, a second driving wheel, a third driving wheel, and a fourth driving wheel. When the first driving wheel has a toothed portion that meshes with the gear 31, the gear 31 is driven to rotate through the first driving wheel. When the gear 31 rotates, the screw rod 9 is driven to rotate. At this time, the first driving wheel rotates one circle and the gear 31 rotates five circles. When the second driving wheel, the third driving wheel, and the fourth driving wheel cooperate with the gear 31, the number of circles of the gear 31 gradually increases.

[0064] It should be noted that, due to the different heights of the patients, the heights at which the lifting is performed are also different. By adjusting the transmission relationship between the transmission sleeve 30 and the screw rod 9, when the support plate 5 is lifted by the lifting structure, the screw rod 9 can be driven to rotate at the same speed when it is lifted to any height, so that the screw rod 9 can drive the receiving plate 4 to move to the end of the stroke when it rotates;

[0065] It should also be noted that the transmission ratio between the gear set 32 ​​and the gear 31 can be adjusted according to actual production, and this application only explains the principle.

[0066] An electric telescopic rod 28 is also fixedly installed in the installation groove 20. The movable rod of the electric telescopic rod 28 is rotatably connected to the transmission sleeve 30 through a transmission plate 29, and the second transmission rod 27 is also connected to the bidirectional screw rod 14 through a second transmission structure.

[0067] Furthermore, when the bidirectional screw 14 rotates, the second transmission rod 27 is driven to rotate through the second transmission structure, and the second transmission rod 27 rotates to drive the transmission sleeve 30 to follow the rotation. At the same time, the transmission sleeve 30 can slide radially along the second transmission rod 27, and when the transmission sleeve 30 rotates, the screw 9 is driven to rotate through the differential structure;

[0068] Among them, when the distance detection detects the sitting height of the patient after adjustment, the electric telescopic rod 28 is driven to work by converting the data. When the electric telescopic rod 28 works, the transmission sleeve 30 is driven to move radially along the second transmission rod 27 through the transmission plate 29, so that the differential drives the screw 9 to rotate, and the speed between the transmission sleeve 30 and the screw 9 is adjustable.

[0069] The second transmission structure includes a first transmission rod 18 rotatably mounted in the base 1 , the first transmission rod 18 slidingly cooperates with a transmission groove coaxially provided on the bidirectional screw rod 14 , and the first transmission rod 18 is connected to the second transmission rod 27 via a second transmission belt 19 .

[0070] Furthermore, when the bidirectional screw rod 14 rotates, the first transmission rod 18 is driven to rotate accordingly, and when the first transmission rod 18 rotates, the second transmission rod 27 is driven to rotate through the second transmission belt 19;

[0071] The second transmission rod 27 is provided with a guide bar on the outside, and the guide bar is slidably matched with the slide groove provided on the inside of the transmission sleeve 30. The first transmission rod 18 has the same structure as the second transmission rod 27, and the transmission groove has the same structure as the slide groove.

[0072] When the receiving plate 4 moves horizontally, the bidirectional screw rod 14 is driven to follow the movement, which does not affect the transmission relationship between the first transmission rod 18 and the bidirectional screw rod 14 .

[0073] The guide member includes second guide blocks 21 fixedly mounted on both sides of the receiving plate 4 , and the second guide blocks 21 are slidably matched with the first guide grooves 3 provided on the inner wall of the base 1 .

[0074] In summary, the present application elevates the support plate 5 through the lifting structure, so that the patient can align the designated position with the designated height of the spinal correction machine, and pushes the receiving plate 4 and the support plate 5 to the designated position of the spinal correction machine through the pushing structure;

[0075] Because the heights of patients are different, the heights when lifting are also different. By adjusting the transmission relationship between the transmission sleeve 30 and the screw rod 9, when the support plate 5 is lifted by the lifting structure, the screw rod 9 can be driven to rotate at the same speed when it is lifted to any height, so that the screw rod 9 can drive the receiving plate 4 to move to the end of the stroke when rotating;

[0076] This application has a high adaptability and can be adjusted according to patients of different heights. Patients can be transported to designated locations and heights during work. In addition, this application has a high degree of automation, which reduces the workload of medical staff and is highly practical.

[0077] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
