Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to a spinal position frame. Background Art

[0002] During spinal surgery, in order to keep the patient in a specific position and fully expose the surgical site of the spine, a positioning frame is needed to constrain the patient's position. In actual applications, patients with spinal diseases often suffer from cardiopulmonary diseases due to scoliosis, which can cause chest deformity and compress the heart and lungs. When the patient lies prone on the positioning frame, the positioning frame will exert pressure on the patient's chest and restrict the movement of the chest, making it more difficult for the patient to breathe in a specific position.

[0003] To this end, we propose a spinal position frame. Summary of the invention

[0004] The main purpose of the present invention is to provide a spinal position frame.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A spinal position frame comprises a base and a load plate, wherein two first electric push rods and a second electric push rod are installed on the load plate, and a left adjustment frame and a right adjustment frame are installed on the driving ends of the first electric push rod and the second electric push rod respectively, and a plurality of guide frame plates for supporting one end of the left adjustment frame and the right adjustment frame are installed on the top of the load plate, and the guide frame plates are hinged to one end of the left adjustment frame and the right adjustment frame, and a plurality of arc support plates are arranged on the left adjustment frame and the right adjustment frame, and a mounting groove is opened on one of the arc support plates, and an adjustment support plate is slidably connected to the inner wall of the mounting groove, so that Several airbags for supporting the bottom of the adjustment support plate are installed on the inner wall of the installation groove, and the two airbags are connected by a connecting pipe. A pressure detection module for detecting pressure is installed on the top of the airbag, and a pressure regulating valve for regulating the gas pressure in the airbag is installed at the bottom of the arc support plate. The pressure detection module and the pressure regulating valve are connected by a PLC control unit signal. Side panels are installed on both sides of one of the arc support plates, and an arc splint is hinged at one end of the side plate. A third electric push rod for supporting one side of the arc splint is installed on one side of the side plate.

[0007] A further improvement of the present invention is that two symmetrical adjustment push plates are slidably connected to the inner wall of the base, two height adjustment rods are hinged on one side of the two adjustment push plates, and each two height adjustment rods are hinged to each other. A guide plate is slidably connected to the bottom of the load plate, and the guide plate is hinged to the other end of the height adjustment rod.

[0008] A further improvement of the present invention is that two symmetrical driving motors are installed on the base, and the driving ends of the two driving motors are respectively threadedly connected to the two adjusting push plates, and a make way channel for making way for the height adjustment rod is opened on the base, and a connecting hole is opened on the guide plate, and a guide rod matching the connecting hole is fixedly connected to the bottom end of the load plate.

[0009] A further improvement of the present invention is that a plurality of left columns and right columns for supporting part of the bottom of the arc-shaped support plate are respectively installed on the left adjustment frame and the right adjustment frame, and support pads for reducing patient pressure are installed on the top of the arc-shaped support plate and the adjustment support plate.

[0010] A further improvement of the present invention is that two support columns are installed at the bottom end of the adjustment support plate, guide holes for limiting the support columns are opened on the installation groove, and the outer wall of the support column is fixedly connected to a limiting ring.

[0011] A further improvement of the present invention is that a spinal position frame comprises:

[0012] S1. When a patient needs to undergo kyphosis surgery, the load plate is supported by two sets of mutually hinged height adjustment rods, and the patient lies prone on a number of arc-shaped support plates supported above the load plate. When the arc-shaped support plates support the patient, the overall height of the arc-shaped support plates can be adjusted according to the actual needs of the surgery. The position of the adjustment push plate threadedly connected to the load plate can be adjusted by rotating the driving end of the driving motor. One end of the height adjustment rod is hinged to one side of the adjustment push plate, so that the adjustment push plate can push the bottom of the height adjustment rod. The angle between the two mutually hinged height adjustment rods will change, so that the top positions of the two sets of mutually hinged height adjustment rods can be raised. The guide plate slidably connected to the bottom of the load plate can be hinged to the top of the height adjustment rod, so that it can be supported by the height adjustment rod. After the adjustment push plate is pushed and displaced, the position of the load plate can be changed accordingly, so that the height of the load plate can be appropriately adjusted, so that the height of the arc-shaped support plate can be adjusted according to the actual needs of the surgery.

[0013] S2. During the operation, medical staff need to adjust the convexity of the support surface composed of several arc-shaped support plates supporting the patient according to the different degrees of spinal deformity of the patient. When adjusting, the left adjustment frame and the right adjustment frame are pushed respectively by controlling the load plate and the first electric push rod. Several arc-shaped support plates are divided into two parts and are supported and fixed on the left adjustment frame and the right adjustment frame by the left column and the right column. Since the other ends of the left adjustment frame and the right adjustment frame are hinged with the guide frame plate, the arc-shaped support plates of the two parts can be adjusted in angle under the push of the load plate and the first electric push rod, so that the convexity of the several arc-shaped support plates when supporting the patient can be adjusted, and appropriate tension or pressure can be applied to the spine, so as to assist doctors in achieving a more ideal deformity correction effect;

[0014] S3. After the convexity is adjusted, when the convexity decreases, the supporting pressure of the thorax by the adjusting support plate increases. For patients with respiratory dysfunction, the thorax cannot fully expand, which will lead to reduced lung ventilation and make inhalation more difficult. After the pressure on the adjusting support plate increases, the third electric push rod pushes the arc splint hinged on the side plate to temporarily clamp the arc splint on both sides of the thorax to fix the position of the patient's chest. The pressure increase information is then transmitted to the PLC control unit through the pressure detection module, and the pressure regulating valve is controlled by the PLC control unit to control it. The pressure regulating valve controls the flow and pressure of the gas by adjusting the opening of the valve. When the pressure in the airbag exceeds the set value, the pressure regulating valve will automatically open to discharge the excess gas. After the airbag gas is discharged, the support height of the adjustment support plate will be lowered, reducing the pressure on the patient's chest, so that the patient can maintain good breathing when performing kyphosis surgery in the prone position. The arc-shaped splint clamps both sides of the patient's chest to prevent slight movements of the patient's chest from causing movement deviation of the patient's spine during surgery.

[0015] Compared with the prior art, when performing kyphosis surgery on patients, the convexity of the two sets of arc-shaped support plates can be adjusted by the first electric push rod and the second electric push rod, and the height of the load plate can be adjusted to adjust the convexity and height of the patient's spine. When the adjustment support plate is subjected to high pressure, part of the gas can be discharged through the airbag to reduce the pressure between the adjustment support plate and the patient's thorax, so as to facilitate medical staff to perform osteotomy treatment on the patient's spine during surgery, and enable the patient to breathe well when performing kyphosis surgery in the prone position.

[0023] Example 1

[0024] See also Figure 1-Figure 5, including a base 1 and a load plate 2, on which two first electric push rods 21 and a second electric push rod 22 are installed, and the driving ends of the first electric push rod 21 and the second electric push rod 22 are respectively installed with a left adjustment frame 23 and a right adjustment frame 231, and the top of the load plate 2 is installed with a plurality of guide frame plates 232 for supporting one end of the left adjustment frame 23 and the right adjustment frame 231, and the guide frame plates 232 are hinged to one end of the left adjustment frame 23 and the right adjustment frame 231, and the left adjustment frame 23 and the right adjustment frame 231 are provided with a plurality of arc-shaped support plates 3, one of which is provided with a mounting groove 32, and the inner wall of the mounting groove 32 is slidably connected with an adjustment support plate 34, and the installation Several air bags 33 for supporting the bottom of the adjustment support plate 34 are installed on the inner wall of the groove 32. The two air bags 33 are connected by a connecting pipe 331. A pressure detection module 35 for detecting pressure is installed on the top of the air bag 33. A pressure regulating valve 36 for regulating the gas pressure in the air bag 33 is installed at the bottom of the arc support plate 3. The pressure detection module 35 and the pressure regulating valve 36 are connected by a signal through a PLC control unit 37. Side panels 4 are installed on both sides of one arc support plate 3. An arc splint 41 is hinged at one end of the side panel 4. A third electric push rod 42 for supporting one side of the arc splint 41 is installed on one side of the side panel 4.

[0025] In this embodiment, the base 1 is used to be placed flat on the operating table when performing spinal kyphosis surgery on the patient, so that the entire device can be on the operating table and can provide support for the patient in the prone position. During the spinal kyphosis surgery, since osteotomy and reduction are required, the patient lies prone on the device, and the distance between the load plate 2 arranged above the base 1 and the base 1 can be adjusted by adjusting the angle between two sets of mutually hinged height adjustment rods 14, so that the load plate 2 can adjust the height of several arc-shaped support plates 3 above the load plate 2 during the operation, so that when the arc-shaped support plates 3 support the patient, the overall height of the several arc-shaped support plates 3 can be adjusted according to the actual needs of the operation, thereby adjusting the height of the patient's spine for the convenience of medical treatment. During the operation, the nursing staff performs osteotomy treatment on the patient's spine and cooperates with the device to support the patient in a prone position, so that the patient's back can face upward and the spine can be fully exposed to the surgical field of view, which is convenient for the doctor to operate. When the patient lies prone on several arc-shaped support plates 3, the patient's chest position is adjusted to a position corresponding to an arc-shaped support plate 3 in the front and middle position before the operation, so that the adjustment support plate 34 installed on the arc-shaped support plate 3 supports the patient's chest, and then the patient's body is fixed so that the patient can be firmly supported on the arc-shaped support plate 3 during the operation. After the patient lies prone on the arc-shaped support plate 3, the doctor can adjust the supporting convexity of the patient for the patient by the several arc-shaped support plates 3 according to the convexity of the patient's spine, and adjust the left and right sides of the patient's back respectively through the first electric push rod 21 and the second electric push rod 22. The adjusting frame 23 and the right adjusting frame 231 are supported at one end, while the other ends of the left adjusting frame 23 and the right adjusting frame 231 are supported by the guide frame plate 232. The guide frame plate 232 is hinged to one end of the left adjusting frame 23 and the right adjusting frame 231, so that the output ends of the first electric push rod 21 and the second electric push rod 22 can support the bottom of the left adjusting frame 23 and the right adjusting frame 231, and the output ends of the first electric push rod 21 and the second electric push rod 22 can push one end of the left adjusting frame 23 and the right adjusting frame 231, so that the arc-shaped support plate 3 supported on the left adjusting frame 23 and the right adjusting frame 231 can move to both sides, so that the angle between it and the load plate 2 changes, so that the convexity of several arc-shaped support plates 3 when supporting the patient can be adjusted, so that the device can be used for different degrees of Spinal deformity. At the same time, in spinal osteotomy surgery, precise convexity adjustment can better cooperate with the surgery to correct spinal deformity. By adjusting the convexity of the frame composed of several arc-shaped support plates 3, appropriate tension or pressure can be applied to the spine to assist doctors in achieving a more ideal deformity correction effect. When the adjusting support plate 34 supports the patient's thorax, the patient's thorax is under its own pressure and the pressure fixed on the arc-shaped support plate 3. The adjusting support plate 34 continuously exerts a large pressure on the thorax, which directly restricts the movement of the thorax during the patient's breathing. Especially after the convexity is adjusted, when the convexity is reduced, the center of gravity of the body moves forward, making the front of the thorax more closely in contact with the body frame, and the pressure on it increases. The increased pressure limits the mobility of the thorax.Especially during inhalation, the thorax cannot fully expand, which will lead to a decrease in lung ventilation and make inhalation more difficult, thus causing difficulty in breathing for the patient. When the adjusting support plate 34 supports the patient's thorax, the two air bags 33 installed in the mounting groove 32 on the arc-shaped support plate 3 support the adjusting support plate 34 horizontally. After the convexity is adjusted, when the thorax exerts a greater pressure on the adjusting support plate 34, the pressure can be detected by the pressure detection module 35 between the adjusting support plate 34 and the air bag 33. When the pressure detection module 35 is subjected to a greater pressure, the information is transmitted to the PLC control unit 37. The pressure regulating valve 36 is controlled by the PLC control unit 37 to control the opening of the valve to control the flow and pressure of the gas. When the pressure in the air bag 33 exceeds the set value, the pressure regulating valve 36 will automatically open to discharge excess gas to keep the pressure in the air bag 33 stable. When the pressure in the air bag 33 is lower than the set value, the pressure regulating valve 36 can allow external gas to enter the air bag 33 for replenishment. When the device is used to adjust the convexity, if the patient's thorax is subjected to a greater supporting pressure from the adjusting support plate 34, the height of the airbag 33 supporting the adjusting support plate 34 can be lowered to reduce the pressure on the patient's thorax, so that the patient can breathe well when the patient is in a prone position for kyphosis surgery, thereby allowing the device to alleviate the patient's discomfort during surgery and the difficulty in breathing that affects the surgery. At the same time, the two airbags 33 can be connected through the connecting tube 331 to ensure that their internal pressures remain consistent, thereby adjusting the supporting plate 34. For horizontal support, before the airbag 33 is exhausted to lower the support height of the patient by the adjustment support plate 34, the arc splint 41 connected to the top of the side plates 4 fixed on both sides of the arc support plate 3 can apply pressure to the inner part of the arc splint 41 at the output end of the third electric push rod 42, so that it can push the arc splint 41, so that the arc splints 41 on both sides can clamp the two sides of the thorax in advance to prevent the adjustment support plate 34 from moving down. After the support force on the thorax is withdrawn, the thorax will shake slightly, affecting the medical staff's spinal correction surgery on the patient.

When the arc-shaped support plates (3) support the patient, the overall height of the plurality of arc-shaped support plates (3) can be adjusted according to the actual needs of the surgery. The position of the adjustment push plate (11) threadedly connected to the adjustment push plate (11) can be adjusted by rotating the driving end of the driving motor (12). One end of the height adjustment rod (14) is hinged to one side of the adjustment push plate (11), so that the adjustment push plate (11) can be adjusted in height. The bottom of the rod (14) is pushed, and the angle between the two mutually hinged height adjustment rods (14) changes, so that the top positions of the two sets of mutually hinged height adjustment rods (14) can be raised, and the guide plate (15) slidably connected to the bottom of the load plate (2) can be hinged to the top of the height adjustment rod (14), so that it can be supported by the height adjustment rod (14).

S2. During the operation, the medical staff needs to adjust the convexity of the support surface composed of a plurality of arc-shaped support plates (3) for supporting the patient according to the different degrees of spinal deformity of the patient. When adjusting, the load plate (2) and the first electric push rod (21) are controlled to push the left adjustment frame (23) and the right adjustment frame (231) respectively. The plurality of arc-shaped support plates (3) are divided into two parts and are located on the left adjustment frame (23) and the right adjustment frame (231) and are supported and fixed by the left column (24) and the right column (241). Since the other ends of the left adjustment frame (23) and the right adjustment frame (231) are hinged to the guide frame plate (232), the arc-shaped support plates (3) of the two parts can be adjusted in angle under the push of the load plate (2) and the first electric push rod (21), so that the convexity of the plurality of arc-shaped support plates (3) when supporting the patient can be adjusted, and appropriate tension or pressure is applied to the spine, thereby assisting the doctor in achieving a more ideal deformity correction effect.
