Description

DESCRIPTION A CERVICAL IMPLANT Technical Area This invention is placed between two vertebrae, providing easy mobility and cervical spine that helps maintain the intervertebral distance in the preferred position It's about the implant. Prior Art Located in the upper part of the waist, carrying all the weight of this place, and a flexible part of the body. The bone community that allows it to move in this way is called the spine.

The spine, thanks to its mobile structure, is the most important part of the human skeleton and the basic is the axis. It stretches along the back and provides support to the body. The spine in question originates from the vertebrae. The first part of these vertebrae is the neck vertebra (cervical vertebra), the second dorsal vertebra and the third lumbar vertebra, and the last part is the coccyx is bone. Disorders such as accident or tumor in any part of the spinal cord When damage occurs due to surgical methods are applied and different implants are placed. This The implants placed in the neck area from the implants are cervical disc implants.

These implants are placed on the patient as a result of various surgeries. This One of the surgeries is pain, numbness or strength related to cervical disc disease. These are surgeries applied to relieve complaints and findings such as loss of life. Spine soft disc called disc, which acts as a natural shock absorbing cushion between the bones, jelly-like structures. The soft part in the middle part of the discs For reasons, it may herniate from the disc wall and compress the neighboring nerves and spinal cord.

Likewise, bone protrusions (bone protrusions) caused by the wear of the discs spurs, calcifications) can compress nerves and spinal cord. With this surgery Head of neck region due to hernia on spinal cord or nerve roots is attempted to be resolved. Herniated disc and bone between the two affected vertebrae The protrusions are usually removed by a surgical operation on the front of the neck.

After the disc is removed, fusing the upper and lower vertebrae together, two neighboring bones Pre-prepared to Prevent collapse by filling the gap between implants are used. Thus, the neck movements of the operated patient is not restricted.

Many different blade opening systems in implants used today is used. However, eccentric movement in these implants used today. As a result, a moving element comes out of the implant. not used.

They can move freely to a certain extent. This In this way, the relative movements of the vertebrae relative to each other can be easily achieved. is carried out.

In the cervical implant (l), which is included in one embodiment of the invention, there is also a mobile element (4) and actuator (5). Said moving element (4) and the activator (5) is located in both the upper part (2) and the lower part (3), and the upper part (2) to the upper vertebra and the lower part (3) to the lower vertebrae. it provides. The movable element (4), at least one body (4.1), in said body At least one eccentric hole (4.2) located in (4.1) and located on the vertebral side facing surface area consists of more than one tooth (4.3). of said eccentric hole (4.2) The two diameters perpendicular to each other are different from each other and one diameter is slightly larger than the other. is big. In the cervical implant (1), besides the movable element (4), there is also a activator (5) is located. The said activator (5) has at least one cylinder (5.1) is the largest cylinder located at one end of the cylinder (5.1) and in which a converter is placed. a minimum of one rotator head (5.3), the actuator (5) the upper hole (2.2) or the lower hole (3.2) When it is placed, it is opened to prevent it from coming out of its position. a small channel (5.2), located off-center in the cylinder (5.1), also positioned in the eccentric hole (4.2) so that the actuator (5) by applying force to the movable element (4) as it is rotated about its axis. at least one enabling the moving element (4) to be moved in the preferred direction has the extension (5.4). When the cervical implant (1) is ready for use extension (5.4) located in the actuator (5), the extension (5.4) located in the movable element (4) eccentric hole (4.2) is in the recessed position. Extension (5.4), converter placing a turning apparatus per head (5.3) and placing a around the central axis of the actuator (5) in case of torque can rotate in a circle. with a word If the actuator (5) rotates about its axis, the extension (5.4) is also in a certain circular orbit because it is off the center axis of the cylinder (5.1). is forced to move. This movement of the extension (5.4) is both horizontal and It also causes the application of a force in the vertical direction. However, in the horizontal the force applied is one diameter of the eccentric hole (4.2) larger than the other diameter Since the movable element (4) is not forced to move sideways, hinders. However, the diameter of the eccentric bore (4.2) on the vertical side Since it is almost in diameter with (5.4) diameter, the force applied in this direction causes the moving element (4) to be exposed to movement in the vertical direction.

The movement of the movable element (4) from the upper part (2) and the lower part (3), this extension (5.4) thanks to its circulating in the eccentric bore (4.2) and the application of force is carried out.

In the cervical implant (1) included in one embodiment of the invention, there is also a retainer (6). is located. The said holder (6) is attached to both the upper part (2) and the lower part (3). is placed and the actuator (5) is positioned by sitting in the channel (5.2). prevents it from coming out of the ground.

In the cervical implant (1) in one embodiment of the invention, there is also a rib (7) is located. The ribs (7) in question are the upper part (2) and the lower part (3). It is positioned on the surfaces in contact with the vertebrae and sinks into the vertebrae in the upper part (2) and lower part (3) provide better adhesion to the vertebrae. The use and operation of the cervical implant (1) is as follows: is carried out. When the cervical implant (1) is ready for use, the upper part (2) and lower part (3) fit together and therefore curved. (3.3) is in the position that it has entered into the cavity (2.3). Location in the cervical implant (1) The movable element (4) that receives it in its first position is in the upper part (2) and the lower part (3). It is in a hidden location. While the cervical implant (1) is in this state, It is placed between them and brought to the region where it is preferred to be positioned.

Subsequently, one spinner apparatus per spinner (5.3) located in the actuator (5). is inserted and a torque is applied to said converter apparatus, thus it is ensured that the actuator (5) is rotated around its own axis.

If the actuator (5) is rotated about its axis, the extension (5.4) is also forced to turn and the extension (5.4) is also the eccentric hole (4.2) inside the eccentric hole (4.2) both in the vertical direction and moves in the horizontal direction. Horizontal diameter of eccentric hole (4.2) to vertical diameter The horizontal movement of the extension (5.4) is movable because it is larger than the prevents the element (4) from moving horizontally. However, the eccentric hole (4.2) since its vertical diameter is similar to the diameter of the extension (5.4), the rotation in question Due to its motion, a force is applied to the movable element (4) and the movable element (4) is forced to move in the vertical direction. Per converter (5.3) the more rotation angle applied, the more vertical the moving element (4) movement is also 0. Extension (5.4), upper part (2) or lower part (3) When it comes to the closest position to the surface that touches the vertebra, the movable element (4) also It reaches the maximum level that it can move in the vertical direction. in this location while it penetrates the vertebra the most, thus maximizing its adhesion. raises the level. In the case of flipping after this moment, this time it is moving. element (4) moves in the opposite direction and again the upper part (2) or the lower part (3) tends to enter. In short, the activator (5) the more it is rotated around its axis, the movable element (4) will likewise be 0. From there it can move forward and backward in the vertical direction.
