Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a spinal frame. Background Art
[0002] Patients with ankylosing spondylitis and kyphosis have spinal fusion and overall or partial kyphosis, which affects normal vision (inability to look straight), walking, sitting and lying posture (in severe cases, inability to stand upright or lie flat), cardiopulmonary and digestive functions, and the patient's mentality and mental health. The current surgical treatment method is spinal osteotomy to reduce the kyphotic spine or change it to lordosis. The commonly used method is pedicle osteotomy. After osteotomy, correction is required, which is also the most critical step of the operation.
[0003] There are two commonly used methods in clinical practice: using human power to lift the patient's lower limbs or chest to close the osteotomy gap. The disadvantage of this method is that the force is unstable and can easily cause displacement of the osteotomy end. In severe cases, it can cause nerve damage or paraplegia. It also increases the risk of contaminating the surgical area and causing infection. Another method is to use intraoperative pressure on the screw to close the osteotomy gap, but this method has limited correction strength and is prone to complications. Summary of the invention
[0004] In view of the above deficiencies in the prior art, the utility model provides a spinal frame suitable for clinical use, with good stability, large correction force and high degree of automation.
[0005] To solve the technical problems, the utility model provides the following technical solutions: a spinal frame, comprising a base, on which a correction component is installed, the correction component comprising arc-shaped plates arranged opposite to each other and a driving member for driving the arc-shaped plates to rotate, the driving member comprising a retractable push rod, the inner ends of the arc-shaped plates arranged opposite to each other are hinged on the base, the outer ends of the arc-shaped plates are hinged on one end of the push rod, and the other end of the push rod is hinged on the base, the arc-shaped plate is driven to rotate around the hinge between the inner end of the arc-shaped plate and the base by extending or shortening the push rod, and the push rod rotates around the hinge between the inner end of the push rod and the base, and the rotation plane of the push rod and the rotation plane of the arc-shaped plate are in the same plane.
[0006] Furthermore, connecting plates are installed on opposite sides of the base, the connecting plates are connected through a first hinge shaft, and the arc plate is hinged on the first hinge shaft.
[0007] Furthermore, the inner end of the arc-shaped plate includes a plurality of connecting sleeves, and the plurality of connecting sleeves are sleeved on the first hinge shaft.
[0008] Furthermore, first ear plates are installed on the base and are arranged opposite to each other. The first ear plates are connected through a second hinge shaft, and the driving member is hinged on the second hinge shaft.
[0009] Furthermore, the driving member includes a driving motor, and the driving motor electrically controls the extension or shortening of the push rod.
[0010] Furthermore, the driving motor is connected to a control module for extending or shortening the push rod, and the user connects to the control module through an external controller.
[0011] Furthermore, the spine frame is made of carbon fiber material.
[0012] Furthermore, the lower end surface of the arc-shaped plate is provided with second ear plates which are arranged opposite to each other, and the outer end of the push rod is arranged between the second ear plates which are arranged opposite to each other.
[0013] Furthermore, the spinal column frame includes a displacement sensor for measuring the push-out length of the push rod.
[0014] Furthermore, the spinal column frame includes a display screen for displaying data, and the displacement sensor data is displayed on the display screen.
[0015] Beneficial Effects
[0016] The utility model provides a spinal frame, which adopts an arc-shaped plate for support and correction, and the arc-shaped plates are relatively arranged and hinged on a base, and rotate around a hinge point to form an arched "seagull-shaped" angle, so as to meet the need for resetting the spine during surgery, and one end of a push rod is hinged to the outer section of the arc-shaped plate, and the other end of the push rod is hinged to the base. The push rod is extended and retracted to drive the arc-shaped plate to rotate, and the arc-shaped plate, the push rod and the base are hinged to each other to achieve a stable triangular structure, so that the whole is more stable during operation and has stronger supporting force.
[0017] The control module controls the drive motor, which in turn controls the extension and retraction of the push rod, thus reducing human involvement, making it more labor-saving, convenient, and more stable.
[0018] The length of the push rod is calculated by the displacement sensor. Since the push rod drives the arc plate to rotate, the rotation angle of the arc plate is calculated through the lengths of each side and displayed on the display screen, so that medical staff can see the correction angle of the arc plate more intuitively, making adjustment more convenient.

[0033] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.
[0034] See also Figure 1-3 As shown in this embodiment: a spinal frame includes a base 1, on which a correction component is installed, the correction component includes arc-shaped plates 2 arranged opposite to each other and a driving member 3 for driving the arc-shaped plates 2 to rotate, the driving member 3 includes a retractable push rod 3.1, the inner ends of the arc-shaped plates 2 arranged opposite to each other are hinged on the base 1, the outer ends of the arc-shaped plates 2 are hinged to one end of the push rod 3.1, and the other end of the push rod 3.1 is hinged to the base 1, and the arc-shaped plate 2 is driven to rotate around the hinge between the inner end of the arc-shaped plate 2 and the base 1 by extending or shortening the push rod 3.1, and the push rod 3.1 rotates around the hinge between the inner end of the push rod 3.1 and the base 1, and the rotation plane of the push rod 3.1 and the rotation plane of the arc-shaped plate 2 are in the same plane.
[0035] The arc-shaped plates 2 arranged opposite to each other include a left arc-shaped plate 2 and a right arc-shaped plate 2 .
[0036] For example, when used, Figure 2As shown, the patient lies prone on the top surfaces of two pairs of arc-shaped plates 2, wherein the front chest lies on the top surface of the left arc-shaped plate 2, and the crotch lies on the top surface of the right arc-shaped plate 2. The abdomen is exposed on the gap between the left arc-shaped plate 2 and the right arc-shaped plate 2.
[0037] An arc plate 2 is used for support correction, and the arc plate 2 is relatively arranged and hinged on the base 1. By rotating around the hinge point, the arched rotation is formed into a "seagull-shaped" angle to meet the needs of spinal repositioning during surgery. One end of the push rod 3.1 is hinged to the outer section of the arc plate 2, and the other end of the push rod 3.1 is hinged to the base 1. The push rod 3.1 is extended and retracted to drive the arc plate 2 to rotate. The arc plate 2, the push rod 3.1 and the base 1 are hinged to each other to achieve a stable triangular structure, which makes the whole more stable during operation and has stronger supporting force.
[0038] In some embodiments, Figure 6 As shown, connecting plates 4 are installed on the opposite sides of the base 1, and the connecting plates 4 are connected by a first hinge shaft 5. The arc plate 2 is hinged on the first hinge shaft 5. It should be noted that through the setting of the connecting plates 4, a gap is directly left between the relatively arranged arc plates 2 to prevent the relatively arranged arc plates 2 from causing wear and collision during rotation.
[0039] In some embodiments, Figure 4-Figure 5 As shown, the inner end of the arc plate 2 includes a plurality of connecting sleeves 2.1, and the plurality of connecting sleeves 2.1 are sleeved on the first hinge shaft 5. It should be noted that the connection between the connecting sleeves 2.1 and the first hinge shaft 5 is more tightly connected by the setting of the connecting sleeves 2.1.
[0040] In some embodiments, Figure 6 As shown, the base 1 is provided with first ear plates 6 which are arranged opposite to each other. The first ear plates 6 are connected via a second hinge shaft 7. The driving member 3 is hinged on the second hinge shaft 7. It should be noted that, through the connection between the first ear plate 6 and the second hinge shaft 7, the driving member 3 is more tightly connected to the base 1 and the operation is more stable.
[0041] In some embodiments, Figure 6 As shown, the driving member 3 includes a driving motor 3.2, and the driving motor 3.2 electrically controls the extension or shortening of the push rod 3.1. It should be noted that the extension or shortening of the push rod 3.1 is controlled by the driving motor 3.2, which reduces human involvement, is more labor-saving, and is more stable.
[0042] In some embodiments, Figure 7 As shown, the driving motor 3.2 is connected to a control module 8 for extending or shortening the push rod 3.1. The user connects the control module 8 via an external controller 9. It should be noted that the driving motor 3.2 is controlled by the control module 8, thereby achieving control of the push rod 3.1, which is more convenient.
[0043] In some embodiments, Figure 1 As shown, the spinal frame is made of carbon fiber material. It should be noted that carbon fiber material has good X-ray perspective effect, and can achieve X-ray to irradiate the user through the spinal frame.
[0044] In some embodiments, Figure 4-Figure 6 As shown, the lower end surface of the arc plate 2 is installed with second ear plates 10 arranged opposite to each other, and the outer end of the push rod 3.1 is arranged between the second ear plates 10 arranged opposite to each other. It should be noted that by arranging the outer end of the push rod 3.1 between the second ear plates 10 arranged opposite to each other, the relative movement between the arc plate 2 and the push rod 3.1 is prevented, so that the arc plate 2 and the push rod 3.1 are more tightly connected, and the operation of the whole device is more stable.
[0045] In some embodiments, Figure 1 As shown, the spine frame includes a displacement sensor 11 for measuring the push rod 3.1 push length. It should be noted that the push rod 3.1 length is calculated by the displacement sensor 11. Since the push rod 3.1 drives the arc plate 2 to rotate, the rotation angle of the arc plate 2 is calculated by the length of each side.
[0046] In some embodiments, Figure 1 As shown, the spinal frame includes a display screen 12 for displaying data, and the data of the displacement sensor 11 is displayed on the display screen 12. It should be noted that the rotation angle of the curved plate 2 is displayed on the display screen 12, so that medical staff can more intuitively see the correction angle of the curved plate 2, thereby making adjustment more convenient. This solves the problem that the state of the equipment cannot be observed during surgery, the position of the spine cannot be adjusted well, and the angle cannot be displayed.
[0047] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
